Answer:

[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]

Step-by-step explanation:

The objective of this question is to find the probability that:

Exactly 11 of them major in STEM

So, Let assume X to be the random variable that follows a binomial distribution:

Then [tex]X \simeq Bin ( 36, 0.31)[/tex]

The probability that exactly 11 of them major in STEM can be computed as:

[tex]P(X =11 ) = ^{36} C_{11} (0.31)^{11} (1-0.31) ^{36-11}[/tex]

[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]P(X =11 ) =600805296 \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]

Thus; the probability that exactly 11 of them major in STEM is 0.1429

Answer:

x=20

Step-by-step explanation:

Since supplementary angles =180 degrees, we need to write the equation as follows:

5x-30+x+90=180

Then you need to add like terms:

6x+60=180

Then you need to subtract 60 from both sides (60 and 180)

6x=120

Then divide both sides by 6 to get

x=20

Answer: C=-3t+30

Step-by-step explanation:

The equation of remaining chocolate C  in terms of t could be C =30 - 3t.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given that the Initial number of chocolates in box = 30

Also after 8 nights, number of remaining chocolates = 6

Then we have

In 8 nights, 24 chocolates were treated.

In 1 night, 3 chocolates were treated.

The equation of remaining chocolate C  in terms of t can be written by;

C =30 - 3t.

Answer:

The answer is 74 cm

Step-by-step explanation:

The area of a rectangle = length × width

Since we are finding the width

We have

From the question

area = 6216 cm²

length = 84 cm

The width is

We have the final answer as

74 cm

Step-by-step explanation:

Answer: 64%

Step-by-step explanation:

Given: Size of photo = 7-by-5-inch

Area of photo = 7 x 5 = 35 sq. inches   [ Area = Length x width]

Required size = 4.2 inches by 3 inches

Area of required size = 4.2 x 3 =12.6 sq. inches

Area reduced =Area of photo  - Area of required size = 35-12.6 =22.4 sq. inches

Percentage of the photo need to be reduced to in order for it to fit in the allotted space

[tex]=\dfrac{22.4}{35}\times100=64\%[/tex]

Percentage of the photo need to be reduced to in order for it to fit in the allotted space = 64%

Answer: 33 & 1/5

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 332 by 10 and keep only what is to the left of the decimal point:

332 / 10 = 33.2000 = 33

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

332 - (10 x 33) = 2

Step 3 - Put Together

Keep the original denominator and use the answers from Step 1 and Step 2

Step 4 - Minimize

Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 332/10 as a Mixed Number.

Answer:

x=6,0

y=0,-18

Step-by-step explanation:

Answer:

x-intercept: (6,0)

y-intercept: (0,-18)

Step-by-step explanation:

To find the x-intercept, set y=0 and solve for x.

2y=+17=6x-19

0+17=6x-19

6x=36

x=6

(6,0)

To find the y-intercept, set x=0 and solve for y.

2+17=6x-19

2y+17=0-19

2y=-36

y=-18

(0,-18)

Answer: $14

Step-by-step explanation: You have to multiply 20 by .3 (30%) which is 6. Now you subtract 6 from 20 and get 14.

Answer:

A = (1/2)*b*h

objective: find dA/dt

given: b = 26, db/dt = 2, b = (1/2)*h

since we are given db/dt lets get area in terms of b

since b = (1/2)h that means h = 2b

so A = (1/2)*b*(2b) = b^2

Take derivative wrt time, t

dA/dt = 2b*db/dt

Answer:

The boxes are classified as underweight or not. X, the number of underweight boxes will be approximately ___normally___distributed

Step-by-step explanation:

For a normal distribution the sample size must be less than or equal to 30.

The central limit theorem states that if a variable X from a population has a mean u and a finite variance σ² then the sampling distribution of the sample mean x bar approaches  a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.

In the given question the sample size n= 10 and population size N= 3000.

Here n < 30 . But if the population is normal this theorem holds true for sample size n < 30.

The number of underweight boxes should be normally distributed.

It is the distribution where the sample size should be lower than or equal to 30

Since the size of the sample is n = 10 and the size of the population is N = 3000

So here n should be less than 30

Therefore, it is normally distribution.

Answer:

Step-by-step explanation:

take 4a okay

so you take the first box and multiply it with the one that is in its spot in the other box.

so -6/7 times 0

-1/7 times -1

-1 times -7

0 times 6

so next you would write the answers to those problems in the spots you multiplied

soooo....

-6/7 times 0

that answer goes in the top left
