Find the distance between the points (9,0) and (1,6).

Answer:

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

A local bakery has determined a probability distribution for the number of cheesecakes it sells in a given day. The distribution is as follows:

Number sold in a day 0 5 10 15 20 Prob (Number sold) 0.06 0.2 0.13 0.08 0.53

Find the number of cheesecakes that this local bakery expects to sell in a day.

A) 20 B) 14.1 C) 14.16 D) 10

Answer:

Given the data:

14.1

Step-by-step explanation:

X : ____0 ___5 ____10 _____15 _____20

P(X): _0.06 _0.2 __0.13 ___ 0.08 ____ 0.53

Exoectwd number of cheesecakes to be sold per day :

E(X) = ΣX*P(x)

E(X) = (0*0.06) + (5*0.2) + (10*0.13) + (15*0.08) + (20*0.53)

E(X) = 0 + 1 + 1.3 + 1.2 + 10.6

E(X) = 14.1

Find the number of cheesecakes that this local bakery expects to sell in a day.

A) 20 B) 14.1 C) 14.16 D) 10

We have given data is,

P(X):    0.06    0.2      0.13      0.08      0.53

E(X) = ΣX*P(x)

Therefore by using the formula we get,

E(X) = (0*0.06) + (5*0.2) + (10*0.13) + (15*0.08) + (20*0.53)

E(X) = 0 + 1 + 1.3 + 1.2 + 10.6

E(X) = 14.1

Therefore,the number of cheesecakes that this local bakery expects to sell in a day is 14.1

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.

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

-1/7 times -1

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:

V(t) = 18t²-18t-360

Step-by-step explanation:

Given the equation of motion of particle expressed as:

s(t) = 6t³-9t²-360t

Velocity is the change in displacement of a body with respect to time.

V(t) = ds(t)/dt

V(t) = 3(6)t²-2(9)t¹-360

V(t) = 18t²-18t-360

Hence the function of the velocity is V(t) = 18t²-18t-360

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:

Answer:

μ₀ = 89

Step-by-step explanation:

A study has shown that  23 %  of all College textbook cost 95 $ or more,  then if the area under the bell shape curve is 23 % in the right tail, then

z(score ) = 0,74          ( 0,23 ≈  0,2296  from z table )

Then z(score) = ( x - μ₀ ) / σ

0,74  =  ( 95 -  μ₀ ) / 8,5

0,74*8,5 = 95 -  μ₀

6,29 - 95 = - μ₀

μ₀ = 88,71

μ₀ = 89

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:

-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.
