A committee must be formed with 3 teachers and 3 students. If there are 10 teachers to choose from, and 9 students, how many different ways could the committee be made?
Answers
Answer:
10080 ways
Step-by-step explanation:
First we find the amount of combinations of teachers who can be chosen, which is denoted by 10 choose 3 (10 nCr 3), shown below:
10! / (3! * 7!) --> 120
Next to find the amount of combinations of students, you evaluate 9 choose 3(9 nCr 3), shown below:
9! / (3! * 6!) --> 84
To find the total number of combinations, you multiply the teachers combinations by the students combinations:
120 * 84 = 10080
A shopper buys cat food in bags of 33 lbs. Her cat eats \frac{3}{4}
4
3
lb each week. How many weeks does one bag last?
Answers
Total of 44 weeks does one bag last.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator
Total amount of cat food = 33 lbs in one bag
Amount of food cat eats each week = 3/4 lb = 0.75 lb
Number of weeks one bag of cat food last = 33 / 0.75
= 44
Hence one bag of cat food will last for 44 weeks.

Step-by-step explanation:
These are independent events because of probability of first event is not affecting the probability of another event .
probability of getting 4 on first try is 1 / 6
probability of getting six on second try is also 1 / 6 and then probability of getting more 6 on next try is again 1/6
so combined probability is 1/6 ×1/6 ×1/6= 1/216
The length of an arc of a circle is one-eighth the circumference of the circle.Find the angle subtended by this arc at the centre if the radius of the circle is 14cm
Answers
Given:
The radius of the circle is 14 cm.
The length of an arc of a circle is one-eighth the circumference of the circle.
To find:
The angle subtended by this arc at the center.
Solution:
Formula for arc length is:
[tex]s=2\pi r\times \dfrac{\theta }{360^\circ}[/tex] ...(i)
Where, r is the radius and [tex]\theta [/tex] is the central angle.
The length of an arc of a circle is one-eighth the circumference of the circle.
[tex]s=\dfrac{1}{8}(2\pi r)[/tex] ...(ii)
Where, [tex]2\pi r[/tex] is the circumference of the circle.
Using (i) and (ii), we get
[tex]2\pi r\times \dfrac{\theta }{360^\circ}=\dfrac{1}{8}(2\pi r)[/tex]
[tex]\dfrac{\theta }{360^\circ}=\dfrac{1}{8}[/tex]
[tex]\theta =\dfrac{360^\circ}{8}[/tex]
[tex]\theta =45^\circ[/tex]
Therefore, the central angle is 45 degrees.

kilometers per minute and the height h(t) of the prism is increasing at a rate of 10
kilometers per minute. At a certain instant to, the base's side is 4 kilometers and the

prism at that instant?
Match each expression with its given value.
Answers
The rate of change of the surface area A(t) of the prism is 136 kilometers per minute.
What does rate of change mean?
An indicator of how one quantity changes in proportion to another is called a rate of change. If x and y are the independent and dependent variables, respectively, then the rate of change is equal to y-to-x conversions. Positive or negative change rates are possible.
Surafce area of a prism is equal to
2(Area of base) + (perimeter of base)(height)

It is given that db/dt= -7 and dh/dt -=10.
At a particular instant b= 4km, h=9 km.
Now we will substitute the values in this formula:
[tex]\frac{ds}{dt}=-4*4*7-4*4*7+ 4*9*10\\\frac{ds}{dt}=136[/tex]

Looking at the options, first check the leading term is a perfect square. They all are so we can’t eliminate anything. Next we check if the last term is a positive perfect square. The third option is not positive so we can eliminate that one.
Finally we check the center term. The first one does not have a middle term so we can eliminate that one.
The center term must be 2 times the square root of the first times the square root of the last.
The second option - square root of first term is 2m, square root of last term is 3n. 2*2m*3n is 12mn. That is not the middle term so the second option is not right.
The last option - square root of first term is 4x, square root of last term is 3y. 2*4x*3y is 24xy. That is the middle term. So the last option is the correct answer.

Mississipi has the lowest income at 40.6 thousand dollars.Mississippi also has about 207 bacherlors degree per 1000 people what does the linear model estimate for that number of bachelors degrees per 1000 per person for Mississippi based on the median income? How good is this estimate?
Answers
Answer: A linear model is a type of mathematical equation that describes the relationship between two variables, such as median income and the number of bachelor's degrees per 1000 people. In order to estimate the number of bachelor's degrees per 1000 people for Mississippi based on the median income, you would need a linear equation that describes that relationship.
Without that equation, it's not possible to estimate the number of bachelor's degrees per 1000 people for Mississippi based on the median income.
Additionally, without more information about the data that the model was trained on, the correlation between median income and the number of bachelor's degrees per 1000 people and how accurate and reliable the model is, it's difficult to determine the goodness of this estimate. However, in general, a linear model may provide only a rough estimate, especially if the relationship between the variables is complex or non-linear.

Factorize the expression, 10ab (a − 2b)³ +24ab² (3a − 6b)²
Answers
Explanation : Group and factor out the greatest common factor (GCF), then combine.
Answer:
226a³b² - 824ab³ + 984b⁴
Step-by-step explanation:
We can factorize the given expression by expanding the two binomials and then combining like terms.
First, expand the two binomials:
10ab (a − 2b)³ +24ab² (3a − 6b)² = 10ab(a³ - 6a²b + 12ab² - 8b³) + 24ab²(9a² - 36ab + 36b²)
Then, combine like terms:
= 10ab(a³ - 6a²b + 12ab² - 8b³) + 24ab²(9a² - 36ab + 36b²)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)
= 226a³b² - 824ab³ + 984b⁴

Answer:

Step-by-step explanation:
A circle is 360 degrees
The angles will add to 360 degrees
x/2 + 59 + x/4 + x = 360
Subtract 59 from each side
x/2 + x/4 +x +59-59 = 360 -59
x/2+x/4+x = 301
Combine like terms
2x/4 +x/4 +4x/4 = 301
7/4x = 301
Multiply each side by 4/7 to isolate x
4/7 * 7/4 x = 301 *4/7
