It will take Mr. White at least 3 years to earn $165 in interest at an annual simple interest rate of 5% on his $550 deposit.
To solve the given problem, we can use the formula for simple interest:
I = P × r × t
P = $550 is the initial deposit
r = 0.05 is the annual interest rate
I = $165 is the amount of interest earned
We can rearrange the formula to solve for t:
t = I ÷ (P × r)
Substituting in the values we know,
t = $165 × ($550 × 0.05)
t = 3 years

If the rate of potato increases by 20% and the rate of onion decreases by 10%, the total cost of 5 kg potato and 7 kg onion will be Rs. 618. By what percent the cost of 1 kg onion is more
Step-by-step explanation:
Here , the eqn is given as,
Let 1 kg onion cost Rs. y and 1kg potato cost Rs. y then,
3x + 2y= 240....eqn i
The When rate of potato increases by 20 percent,
New rate of unit kg potato becomes,
[tex]x \: + \: 20\% \: of \: x[/tex]
i.e. Rs.6x/5
And when price of onion decreases by 10% ,
New unit price is ,
[tex]y - 10\% \: of \: y[/tex]
i.e. Rs.9y/10
Now the second eqn becomes ,
20x + 21y= 2060
By using elimination method we get x= Rs 40 and y= Rs.60
Finally, we have to find percent change i.e
{(cost of 1kg onion - cost of 1kg potato)/ cost of 1kg potato}x 100%
This gives the ans as 50%
Suppose the weights of sumo wrestlers are normally distributed with a mean of 330lbs and a standard deviation of 15lbs. An up and coming competitor wants to defeat wrestlers whose weights are in the top 10%. What is the minimum weight of the sumo wrestlers at the highest weight of the league? Round your answer to the nearest whole number, if necessary.
I have to figure out how to use Excel's NORM.INV() function to solve this.
Answer: To use Excel's NORM.INV() function to solve this problem, we can follow these steps:
Determine the z-score corresponding to the top 10% of the distribution. We can use the NORM.INV() function to find this value. Since we want the top 10%, we'll use a probability of 0.9 and a mean of 330lbs and a standard deviation of 15lbs. In Excel, we can use the formula:
=NORM.INV(0.9,330,15,TRUE)
This gives us a z-score of 1.281552.
Once we have the z-score, we can use the formula for a normal distribution to find the corresponding weight. The formula is:
z = (x - μ) / σ
where z is the z-score, x is the weight we're trying to find, μ is the mean weight (330lbs), and σ is the standard deviation (15lbs).
Rearranging this formula to solve for x, we get:
x = z * σ + μ
Substituting in the values we know, we get:
x = 1.281552 * 15 + 330
This gives us a weight of approximately 349lbs.
Therefore, the minimum weight of the sumo wrestlers at the highest weight of the league is about 349lbs, rounded to the nearest whole number.
Step-by-step explanation:
For the function f(x) = 2 (x − 1), find ƒ−¹(x).
Answer:
To find ƒ⁻¹(x), we need to solve for x in terms of ƒ⁻¹(x).
So, we start with the equation:
x = 2 (ƒ⁻¹(x) - 1)
We isolate ƒ⁻¹(x) by dividing both sides by 2 and adding 1 to both sides:
ƒ⁻¹(x) = (x/2) + 1
Therefore, the inverse of the given function f(x) is:
ƒ⁻¹(x) = (x/2) + 1
DIlate by a scale factor of 3
Dilation is a transformation that changes the size of an object while keeping its shape the same.
In this case, the scale factor of 3 tells us that the triangle will be three times larger than the original triangle.
To perform the dilation, you would take each vertex of the triangle and multiply the x-coordinate and y-coordinate by 3. For example, if one vertex of the original triangle had coordinates (x, y), the coordinates of that same vertex in the dilated triangle would be (3x, 3y).
It's also worth noting that the dilation is done with respect to a fixed point called the center of dilation. You can think of this point as the "pivot" around which the dilation occurs.
The center of dilation is typically represented by the letter "O".

Since the triangle was rotated by 30 degrees, the angle AOA' is 30 degrees, as is the angle A'OC. Thus, m/AOC is equal to 60 degrees. To demonstrate that BD is perpendicular to CD, OB = OC, angles AOB and COA are both 60 degrees, and angles BOD and COD are both 60 degrees. BD and CD are both perpendicular to the diameter through A.
What is an equilateral triangle?A triangle is said to be equilateral if all three of its sides are the same length and all three of its angles are exactly 60 degrees. It has three regular sides and is a polygon. When dividing an equilateral triangle into two congruent 30-60-90 triangles, the altitude, median, and angle bisector from any vertex are also the same line.
5. Let's identify the circle's intersection points as the equilateral triangle's A, B, and C. All angles in a triangle that is equilateral are 60 degrees. Point A will change locations when the triangle is rotated by 30 degrees; let's designate this new position A'. Since O is the centre of the circle, the angle AOC remains at 60 degrees. Since the triangle has been turned by 30 degrees, the angle AOA' is 30 degrees, as is the angle A'OC. Thus, m/AOC is equal to 60 degrees.
6. The center of the circle is O, and D is the point where the diameter through B intersects the diameter through C. To demonstrate that BD is perpendicular to CD, the center of the circle, OB = OC, and angles AOB and COA are both 60 degrees, so angle BOC is 120 degrees. Angle BOD is a right angle, and angle OBD is half of angle BOC, so it is 60 degrees. Angle COD is also a right angle, and angle OCD is half of angle BOC, so it is also 60 degrees. Since angles OBD and OCD are both 60 degrees, and they are angles in a triangle, the third angle (angle BDC) must also be 60 degrees.
Therefore, triangle BDC is equilateral, and BD = CD. Since BD and CD are both perpendicular to the diameter through A, BD is perpendicular to CD.

What is central limit theorem?A fundamental idea in statistics known as the central limit theorem (CLT) argues that, under specific circumstances, the sampling distribution of the mean of a random sample from any population tends to resemble a normal distribution as the sample size rises.
1. For 95% confidence interval we have:
CI = x ± z*(σ/√n)
Substituting the values:
CI = 400 ± 1.96*(39/√30) = (364.97, 435.03)
2. For 99% confidence interval we have:
CI = p-cap ± z*(√(p - cap(1- p-cap)/n))
Substituting the values:
CI = 165/360 ± 2.58*(√((165/360)*(195/360)/360)) = (0.407, 0.500)
Hence, we can be 99% confident that the true population proportion of married men, 18 or older, is between 0.407 and 0.500.
3. 95% estimate of the mean:
CI = x ± t*(s/√n)
Substituting the values:
CI = 47,000 ± 2.064*(1,050/√26) = (45,424, 48,576)
4. For sample size:
CI = 47,000 ± 2.064*(1,050/√26) = (45,424, 48,576)

uno de los catetos del triangulo rectángulo mide 77cm y la hipotenusa excede al otro cateto en 49 cm.
CALCULA LA HIPOTENUSA
La hipotenusa mide 137 cm.
Podemos utilizar el teorema de Pitágoras para resolver este problema, que establece que en un triángulo rectángulo, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos.
Sea "a" la medida del otro cateto, entonces:
a² + 77² = (a+49)²
Desarrollando los cuadrados y simplificando, tenemos:
a² + 5929 = a²+ 98a + 2401
Restando a ambos lados a², obtenemos:
5929 = 98a + 2401
Restando 2401 a ambos lados, obtenemos:
3528 = 98a
Dividiendo por 98, obtenemos:
a = 36
Por lo tanto, el otro cateto mide 36 cm, y la hipotenusa se puede calcular utilizando el teorema de Pitágoras:
h² = a² + b²
h2 = 36² + 77²
h² = 12996 + 5929
h² = 18925
Tomando la raíz cuadrada en ambos lados, obtenemos:
h = 137
Por lo tanto, la hipotenusa mide 137 cm.

The radius of a circle is 1. What is the length of an arc that subtends an angle of
6radians?
Answer:
pi/6
Step-by-step explanation:
the full arc of the circle is the circumference = 2pi×r.
since r = 1, we get circumference = 2pi.
the full arc of 2pi is for 360° or 2pi radians (hence the definition).
an angle given in radians for the norm circle with radius = 1 IS therefore already the arc length for that angle.
for 2pi the arc length is 2pi.

UV is tangent to ⨀T. What is
Step-by-step explanation:
if we extend the line VT to reach also the opposite side of the circle, we see that this line cuts the circle in half.
the whole arc angle of a half-circle is 360/2 = 180°.
now we can use the exterior angle rule :
the vertex angle (V) = 1/2 × difference of the angles of the intersected arcs.
the intersected arcs are
shorter = angle at T : the arc from U to the circle intersection with the line VT.
longer : the arc from U to the circle intersection with the extended line VT.
shorter + longer = 180°
longer = 180 - shorter
30 = 1/2 × ((180 - shorter) - shorter) =
= 1/2 × (180 - 2×shorter) = 90 - shorter
-60 = -shorter
shorter = 60°

Emilie has a drawer full of color for ribbons the probability of randomly selecting a green ribbon is 84% which of the following describes the likelihood of selecting a green ribbon
When the probability of an event is high, we can say that the likelihood of that event occurring is also high. Conversely, when the probability of an event is low, the likelihood of that event occurring is also low.
What is probability?
In mathematics, probability is a measure of the likelihood that an event will occur. It is a way of quantifying the uncertainty or randomness associated with an event or set of events. The probability of an event is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to occur. For example, the probability of flipping a fair coin and getting heads is 0.5, or 50%, since there are two equally likely outcomes (heads or tails) and getting heads is one of them. Probability theory is a fundamental branch of mathematics that has applications in many areas, including statistics, finance, engineering, and computer science, among others.
Here,
The likelihood of selecting a green ribbon from Emilie's drawer is high, since the probability of randomly selecting a green ribbon is 84%. This means that out of all the ribbons in the drawer, 84% of them are green.
Another way to interpret this is that if Emilie were to randomly select a ribbon from her drawer without looking, there is an 84% chance that the ribbon she selects will be green.

For function F(x)=-4x+8, evaluate and simplify the different quotient
Thus, the simplification of the given function using difference quotient formula is found as 4.
Explain about the difference quotient formula:The difference quotient is the product of the difference between the function values, f(x + h) - f(x), and indeed the difference between the input values, (x + h) - x, given a function f(x) and two input values, x as well as x + h (where h is indeed the distance between x and x + h).
For the given question:
function F(x) = -4x+8
difference quotient formula:
[f(x + h) -f(x)] / h
Put x = x + h
F(x+ h) = -4(x + h) + 8
F(x+h) = -4x -4h + 8
F(x) = -4x+8
Now,
[f(x + h) -f(x) ]/ h = [-4(x + h) + 8 + 4x - 8]/ h
On simplifying:
[f(x + h) -f(x) ]/ h = 4h/h = 4
Thus, the simplification of the given function using difference quotient formula is found as 4.

a) Parent functionThe parent function is the function that remains after scale factors and translations are removed. In general, a transformed function will look like ...
g(x) = c·f((x-a)/b) +d
which scales the function f(x) horizontally by a factor of b, vertically by a factor of c, and translates the result by (a, d).
Here, we recognize that ...
g(x) = -(x -2)³
has c = -1, a = 2, b = 1, d = 0
and the parent function is ...
f(x) = x³
b) g in terms of fUsing the values for a, b, c, d that we recognized above, we have ...
g(x) = -f(x -2)

Additional comment
When scale factors are negative, they reflect the function over the relevant axis. Here, the negative vertical scale factor reflects the function vertically over the x-axis. The translation is 2 units to the right.
Please help me describe how to simplify this expression.
we have successfully simplified the expression x⁵-x³ into x³(x + 1)(x - 1). This can be useful for further algebraic manipulation or simplification in larger expressions.
How to simplify?
To simplify the expression x⁵-x³, we can factor it using the distributive property of multiplication. First, we can factor out x³ from both terms:
x⁵ - x³ = x³(x² - 1)
Now, we can further simplify by recognizing that x² - 1 is a difference of squares, which can be factored into (x + 1)(x - 1). So, we have:
x⁵ - x³ = x³(x² - 1) = x³(x + 1)(x - 1)
This is the fully simplified form of the expression. We can also expand the expression to verify that it is equivalent to the original expression:
x³(x + 1)(x - 1) = (x³ * x) + (x³ * -1) + (x³ * 1) + (x³ * -1) = x⁴ - x³ + x³ - x³ = x⁴ - x³
So, we have successfully simplified the expression x⁵-x³ into x³(x + 1)(x - 1). This can be useful for further algebraic manipulation or simplification in larger expressions.

given: MATH is a parallelogram
prove: MT bisects AH
Answer:
Step-by-step explanation:
In a parallelogram, opposite sides are parallel and equal.
MA // HT & AH is transversal.
∠MAG ≅ ∠GHT {Alternate interior angles are equal} --Angle
MA = HT {MATH is a parallelogram} ---> Side
MA // HT & MT is transversal.
∠AMG ≅ ∠HTG {Alternate interior angles area equal} ---->Angle
ΔMGA ≅ ΔTGH { Angle side angle congruent}
AG = HG {CPCT}
