Answers

Answer 1

Here is the full question.

In city A, the temperature rises 9° F from A.M to 9 A.M. Then the temperature drops 8°F from 9 A.M. to 10 A.M. in city B, the temperature drops 1°F from  8 A.M. to 9 A.M. Then the temperature drops 3°F from 9 A.M. to 10 A.M.

Write an expression that represents the change In temperature from  8 A.M. to 10 A.M for each city. Simplify and interpret each sum. Use a pencil and paper. Which expression represents the change in temperature for city A?

Answer:

In City A, the expression for the change in temperature is = 9 + (-8)

The amount the temperature changes for City A = 1°F

In City B, the expression for the change in temperature is -1 + (-3)

The amount the temperature changes for City B = -4°F

Thus, City A has a greater change in temperature.

Step-by-step explanation:

From the information above; Given that:

In City A, the rise in temperature from 8 A.M to 9 A.M is = 9°F

In City A, the drop in temperature from 9 A.M to 10 A.M = 8°F

Similarly;

In City B, the drop in temperature from 8 A.M to 9 A.M = 1°F

In City B, the drop in temperature from 9 A.M to 10 A.M = 3°F

For City A

The temperature change from 8 A.M to 10 A.M are :

8 A.M to 9 A.M = +9°F

9 A.M to 10 A.M = -8°F

In conclusion, The sum for the change from 8 A.M to 10 A.M = 9 + (-8) = 1°F

For City B

The temperature change from 8 A.M to 10 A.M are:

8 A.M to 9 A.M = -1°F

9 A.M to 10 A.M = -3°F

In conclusion, The sum for the change from 8 A.M to 10 A.M = -1 + (-3) = -4°F

Let s ( t ) = 6 t 3 − 9 t 2 − 360 t be the equation of motion for a particle. Find a function for the velocity.

Answers

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

Two high schools, Jefferson Hills East and Jefferson Hills West are taking field trips to the state capital. A total of 408
students from Jefferson Hills East will be going in 3 vans and 6 buses. A total of 516 students from Jefferson Hills West
will be going in 6 vans and 7 buses. Each van has the same number of passengers and each bus has the same number of
passengers.

Answers

Answer:

see explanation!

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

Answers

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

C(x + 2, - y).

What is a translation?

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:

The translation two units right is represented by x -> x + 2.The reflection over the x-axis is represented by y -> -y.

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

C(x + 2, - y).

Answers

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]

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

Answer:

X intercept: 8,0

Y intercept ( 0,-4)

Step-by-step explanation:

Answer:

(-8,0) , (0,4) and our answer is D which is not given in the choices i even attached the graph so you can double check.

Step-by-step explanation:

Arrange the equation into the standard form [tex]y=mx+c[/tex]

so,

[tex]3x-6y=-24\\3x+24=6y\\y=\frac{3x+24}{6} \\\\y=\frac{3x}{6} +\frac{24}{6} \\\\y=\frac{x}{2}+4[/tex]

[tex]y=mx+c[/tex]

if we compare we get c=4 where c is the y-intercept now for the x-intercept which means the coordinate should be (x,0) because x-intercept means the function cuts/intersects the x-axis at (x,0) so we put the coordinate and the value of m(slope) and c(y-intercept) in our equation.

[tex]y=\frac{x}{2}+4\\\\ put (x,0) in the function\\\\0=\frac{x}{2} +4\\\frac{x}{2}=-4 \\x=-8[/tex]

so finally our x-intercept is (-8,0) and y-intercept is (0,4)

Two professors teach two sections A and B of the same class. Thecourse scores in section A follow a Gaussian random variable of mean 76 and variance64. The course scores in section B follow a Gaussian random variable of mean 67 andvariance 36. What is the probability that the scores of two students, one in sectionA and one in section B, differ by no more than 1 point in absolute value

Answers

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.

What is the coefficient of the term with a degree of two in the product of (2m-9) and (m^2+3m-4)

Answers

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.
