What is the ratio of the radius to the circumference of any circle, using 3.14 for pi?

Answers

Answer 1

Answer:

1 : 6.28

Step-by-step explanation:

The circumference formula is

C = 2πr orC = 2(3.14)r = 6.28r

The ratio of the radius to the circumference is

r/C = 1/6.28

or

r : C = 1 : 6.28
Answer 2

r : C = 1 : 6.28

Formula's:

circumference of any circle: 2πr

radius: r

Their ratio:

radius : circumference

r : 2πr

r : 2(3.14)r

1 : 6.28

C. z = ±29/7
D. no real solutions

Answers

The answer is A. Z=+-13/5

Answer:

Option A, [tex]z =[/tex] ± [tex]13/5[/tex]

Step-by-step explanation:

Step 1:  Add 140 both sides

[tex]25z^2 - 140 = 29[/tex]

[tex]25z^2 - 140 + 140 = 29 + 140[/tex]

[tex]25z^2 = 169[/tex]

Step 2:  Divide both sides by 25

[tex]\frac{25z^2}{25} = \frac{169}{25}[/tex]

Annabelle uses models to compare two decimal numbers. She says 0.24 is greater than 0.4 because 24 > 4.

Which of these explains Annabelle's mistake?

A. Annabelle incorrectly shaded the models. She should shade six more tenths.

B. Annabelle incorrectly counted the number of shaded parts in the models. She should compare 3 shaded parts to 4 shaded parts.

C. Annabelle incorrectly compared hundredths to tenths. She should compare 24 hundredths to 40 hundredths.

Which of the following statements are TRUE about the normal distribution? Check all that apply.
a. A z-score is the number of standard deviations a specific data value is from the mean of the distribution.
b. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean.
c. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean.
d. The mean corresponds to the z-score of 1.
e. The area to the left of a z-score plus the area to the right of that same z-score will always equal 1.

Answers

Using the normal distribution, it is found that statements a, b, c and e are correct.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Hence, only statement D is false, as the mean corresponds to z-score of 0.

​ −3x+y=2
7x−8y=1

Answers

you could use the substitution method. in this you’ll solve one equation for one variable. we’ll do the first one for y.
add 3x to both sides, so y = 3x + 2
then add that into the other equation for y.
7x - 8(3x +2) = 1
7x- 24x - 16 = 1
-17x - 16 = 1
-17x = 17
x= -1
now that you know what x is, you can find out y with the equation we made earlier. y = 3x+2
y = 3(-1) + 2
y = -3 + 2
y = -1

Using a graph is probably the easiest way to compare an exponential function with a polynomial function. There are no algebraic methods for finding points of intersection. ("Trial and error," or "table of values" will work.)

A graph of these two functions shows f(x) > g(x) except on the interval [1, 2]. That is, f(x) > g(x) for x > 2.

If the attendance at a baseball game is to be predicted by the equation Attendance = 16,500 − 75 Temperature, what would be the predicted attendance if Temperature is 90 degrees?

Answers

Attendance = 16,500-75(90)
=16,500-6,750
= 9750

The predicted attendance if Temperature is 90 degrees will be 9750.

How to calculate the equation?

From the information given, the attendance at a baseball game is to be predicted by the equation Attendance = 16,500 − 75 Temperature.

The predicted attendance will be:

= 16500 - 75(90)

= 16500 - 6750

What is Quadratic equation?

The polynomial equations of degree 2 for a single variable of type f(x) = ax2 + bx + c = 0, where a, b, c, ∈ R, and a ≠ zero, are known as quadratic equations. The leading coefficient is referred to as "a," and the absolute term of the quadratic equation is referred to as "c." The roots of the quadratic equation (α, β). are the values of x that satisfy the equation.

Given initial velocity of a projectile = 98 m/s

equation h = -4.9t² + 98t

where t = time and h = height of projectile,

time taken by projectile to hit the ground,

where h = 0

equation will be

-4.9t² + 98t = 0

4.9t² = 98t

4.9t = 98

t = 98/4.9

t = 20 second

Hence time taken is 20 second.

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.
Find the base and the height of the triangle...
.

Answers

Answer:

base(b)=10 and height(h)=6

Step-by-step explanation:

From the question,

base(b)=x feet

height(h)=(x-4) feet

Area(A)=30 square feet

Now,

We know,

Area of triangle(A)=1/2*b*h

or, 30=1/2*x*(x - 4)

or, 30=1/2*x^2 -4x

or, 30*2=x^2 -4x

or, 60=x^2 -4x

or, 0 = x^2 -4x -60

or, 0 = x^2 +6x - 10x -60

or, 0 = x(x + 6) -10(x + 6)

or, 0 = (x+6) (x-10)

Either,

x+6=0. or, x-10=0

or,x= -6. or, x= 10

Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet

Lastly,

Height(h)=X - 4

=10 - 4

=6 feet
