Answer:

If you multiply it is 44,800 ft

If you add it is 64 ft

Step-by-step explanation:

If you multiply 28 x 16 x 10 x 10 = 44,800 ft

If you add 28 + 16 + 10 + 10 = 64 ft

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: 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:

-3

Step-by-step explanation:

First, identify the different possible ways to multiply 2 monomials and get an m^2 term: we can multiply a constant by an m^2 term, or we can multiply an m term by an m term.

Now, we can identify all the combinations of the products that will give a m^2 term:

m^2*-9=-9m^2

3m*2m=6m^2

Now, we just combine the 2 m^2 terms:

-9m^2+6m^2=-3m^2

Therefore, the coefficient of the term with a degree of 2 is -3.

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

-1/7 times -1

Step-by-step explanation:

If Jefferson Hills East takes 3 vans and each van has xx students, then 3x3x students will ride in vans. If the school takes 6 buses and each bus has yy students, then 6y6y students will ride in buses. The total number of students is then 3x+6y3x+6y. It is given that the school has 408 students so 3x+6y=4083x+6y=408.

If Jefferson Hills West takes 6 vans and each van has xx students, then 6x6x students will ride in vans. If the school takes 7 buses and each bus has yy students, then 7y7y students will ride in buses. The total number of students is then 6x+7y6x+7y. It is given that the school has 516 students so 6x+7y=5166x+7y=516.

The system of equations is then { 3x+6y=408 6x+7y=516  

{

3x+6y=408

6x+7y=516

Answer:

X=3

Step-by-step explanation:

First, the 3 spread to the x and the 4 because of distribution property. Then, 3x is moved to the right, and the left turns into 19. The X's turn into 7x, and the -2 is moved to the left which makes it positive. The equation is simplified to 21=7x which means that x=3.

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:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let A denote the score for students of section A.

Let B denote the score for students of section B.

It is provided that:

[tex]A\sim N(76,64)\\B\sim N(67,36)[/tex]

The scores of the students of the two section are independent.

Compute the mean and variance of A - B as follows:

[tex]E(A-B)=E(A)-E(B)=76-67=9\\\\V(A-B)=V(A)+V(B)-2Cov(A,B)=64+36-0=100[/tex]

Compute the probability that the scores of two students, one in section A and one in section B, differ by no more than 1 point in absolute value as follows:

[tex]P(|A-B|\leq 1)=P(-1\leq X-Y\leq 1)[/tex]

                        [tex]=P(\frac{-1}{10}\leq \frac{(X-Y)-E(X-Y)}{\sqrt{V(X-Y)}}\leq \frac{1}{10})\\\\=P(-0.10<Z<0.10)\\\\=P(Z<0.10)-P(Z<-0.10)\\\\=0.53983-0.46017\\\\=0.07966\\\\\approx 0.08[/tex]

Thus, the probability that the scores of two students, one in section A and one in section B, differ by no more than 1 point in absolute value is 0.08.

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)

Using translation concepts, the coordinates of point C, considering A(x,y), are given as follows:

C(x + 2, - y).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, we have that:

Hence the coordinates of point C, considering A(x,y), are given as follows:

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
