Answer is E

Step-by-step explanation:

did the test, also person who answered before was wrong

Considering the situation described, the appropriate test is given by:

E) A two sample t-interval for difference between population means.

In this problem, we will have the data from the sample, hence it is a t-test. We will compare the population means of the two groups, hence a two-sample t-interval is used, and option E is correct.

Answer:

hyperbola with a solid line boundary

(4, -2)

(0, -4)

Step-by-step explanation:

Took one for the team Edge 2021

The shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .

Conic section is a curve obtained by the intersection of the surface of a cone with a plane.

we have,

[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]

And,

The general form of a Conic Section is,

[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]

And,

The Standard form of a  is,

[tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex]

So,

Now,

[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]

Then,

[tex]4x^2-32x-9y^2-36y\leq8[/tex]

Now, taking common,

[tex]4(x^2-8x)-9(y^2+4y)\leq8[/tex]

Now,

Adding 64 and subtracting 36 to both sides ,

We get,

[tex]4(x^2-8x+16)-9(y^2+4y+4)\leq8+64-36[/tex]

Now,

factor the perfect square,

i.e.

[tex]x^2-8x+16=(x-4)^2[/tex]

Now,

[tex]y^2+4y+4=(y+2)^2[/tex]

Now,

[tex]4(x-4)^2-9(y+2)^2\leq36[/tex]

Now,

Divide both sides by 36,

i.e.

[tex]\frac{4(x-4)^2}{36} -\frac{9(y+2)^2}{36} \leq\frac{36}{36}[/tex]

We get,

[tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex]

So, this is the standard form of the given cubic inequality.

Hence, we can say that the shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .

Answer:

Charlie 55 miles per hour

Violet 65 miles per hour

Step-by-step explanation:

Charlie and Violet met for lunch at a restaurant between Memphis and New Orleans. Since, Charlie left Memphis and drove towards New Orleans, and Violet left New Orleans and drove towards Memphis, the total distance that they covered altogether is the total distance between Memphis and New Orleans.

It is given that the distance between Memphis and New Orleans is 394 miles. This means, the total distance both covered = 394 miles

Charlie drove for 4.8 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour

Since, distance = speed multiplied by time

Distance covered by Charlie = 4.8x

Distance covered by Violet = 2(x + 10)

Altogether they covered 394 miles,

So,

394 = Distance covered by Charlie + Distance covered by Violet

394 = 4.8x + 2(x + 10)

394 = 4.8x + 2x + 20

374 = 6.8x

x = 55

Since, x represents the speed of Charlie, the speed of charlie was 55 miles per hour and speed of Violet was 65 miles per hour

1 0.41

2 0.38

3 0.13

4 0.03

5 0.01

X= 1

.13+.03+.01=0.17 (the amount with 3 or more cars)  

0.17/1(Total amount of all probability)= 0.17 has 3 or more cars.

Probability is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability that an adult resident has 3 or more is 0.17

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

The probability distribution of the number of vehicles is given as,

P(x) where x is the number of vehicles.

P(0) = 0.4

P(1) = 0.41

P(2) = 0.38

P(3) = 0.13

P(4) = 0.3

P(5) = 0.1

The probability that an adult resident has 3 or more.

= P(3) + P(4) + P(4)

= 0.13 + 0.03 + 0.01

= 0.17

Thus,

The probability that an adult resident has 3 or more is 0.17
