I hope I didn't just confuse myself it's been YEARS since i've had simple questions like this (i can edit if needed)

Answer:

The significance test that would be used to investigate whether there is convincing evidence at 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream is option C;

C. A linear regression t-test for slope

Step-by-step explanation:

The linear regression t-test for slope is a test for determining the existence of a statistically significant linear relationship between two variables, a independent variable, X and an dependent variable Y in the following form;

Y = B₀ + B₁·X

The test is used to test the regression line slope where we have;

B₀ = The constant

B₁ = The slope also known as the regression coefficient

The given information tested in the question is if an increase in the peaches in the ice cream is associated with an increase in the density of the ice cream, therefore, the test to investigate the relationship between the rate of both variables is the linear regression t-test for slope.

Therefore, we have

Y = B₀ + B₁·X

Where;

X = The percentage of peaches in the ice cream

Y = The density of the ice cream

Answer:

The triangles are not similar

Step-by-step explanation:

The sides are not proportional

36/73 does not equal to 15/30

Answer:

This is an Exponential Decay

Step-by-step explanation:

A = 1200(0.85)⁶

The above expression is an Exponential Decay because 0.85 is less than 1

The formula for Exponential Decay

= y = a (1 - r)^t

We equate both equation together

Where

a = 1200

1 - r = 0.85

t = 6

Solving for r

1 - r = 0.85

r = 1 - 0.85

r = 0.15

Converting to Percentage

r = 15% decay rate

Answer:

X= 7

Step-by-step explanation:

Well first combine like terms

27x-9=180

Isolate from the variable

27x=189

x=7

The final answer is 7

Answer:

x =7

Step-by-step explanation:

( 10x -1) +(17x -8 ) =180

step 1 : since you have a plus sign in between it make it easy

so take care of the parentheses first

10x -1 + 17x - 8 = 180

step 2 : put together thw variable x

10x + 17x -1 -8 = 180

27x -9 =180

step 3 : take out -9 to the right and the sign will change

27x = 180 +9

27x = 189

x = 189 ÷ 27

x = 7

D. 2x − 3y = 18

Answer:

155

Step-by-step explanation:

The problem sounds complicated, but it's not. Let's analyse.

The city manager have come up with an equartion y=11x +12, with Y is the total number of the stores and X stands for how long it has been since 2003.

We can't explain how the manager came up with this equation, so iwe don't need to think of if the equation is real or not. Let's just base on what we have.

Because the equation aboce is a trendy line, it means that it would likely to be true with any X ( number of years since 1990).

In Tracy's case, the year is 2003, so it has been 2003 - 1990 = 13 years since 1990. This is the X in the equation. Now we only need to find Y in the equation, which is the number of retail stores there were in 2003, exactly what the problem asks.

y= 11x + 12

=> In Tracy's case: y= 11*13 + 12= 155

So the number of retail stores there were in 2003 was 155

Step-by-step explanation:

I got it right on edg.

Answer:

[tex] {h =}^{2} = {p}^{2} \: + {b}^{2} [/tex]

[tex] {h}^{2} = {16}^{2} + {12}^{2} [/tex]

[tex] {h}^{2} = 256 + 144[/tex]

[tex]h = \sqrt{400} [/tex]

[tex]h = 20[/tex]

therefore the length of the ladder is 20ft

i can see the question in ascending order

Answer:

100 people

Step-by-step explanation:

In the attached image below we can see that the original survey was done on a total of 50 individuals (12 + 3 + 20 + 15 = 50). Out of these 50, 20 of them answered basketball.

20 / 50 = 0.40 ... multiply by 100 to get percentage

0.40 * 100 = 40%

We can see that this is 40% of the original survey sample population. If we use this same percentage, we can predict how many individuals out of 250 would answer basketball. We calculate this by multiplying 250 by 40% in decimal form, like so...

250 * 0.40 = 100

Finally, we can predict that 100 people would most likely answer basketball.

Step-by-step explanation:

90 + 40 = 130

180 - 130 = 50

Answer:

population = 5652 people

Step-by-step explanation:

area = πr² = (3.14)(6²) = 113.04 mi²

at 50 people/mi², then 113.04 x 50 = 5652 people

Answer:

34.98 yds²

Step-by-step explanation:

To find surface area, we add together the area of each side. We have six sides, but there are three sets of identical sides, so it's easier to calculate.

We begin with the sides with dimensions 2.40 and 2.50. Multiply these together.

2.40 · 2.50 = 6

Since there are two of these sides, we can already say that the combined area of them is 12. So, we start the equation with 12.

Next, the two sides with dimensions 2.34 and 2.50. Multiply these together as well, to get 5.85. Multiply this by two to find the area of both sides, 11.7.

Add to our equation, for 12 + 11.7.

For the final two sides, we have the dimensions 2.34 and 2.40. Multiply to get 5.64. Multiply this again by two to find the area of both sides. We get 11.28. Add this to the equation as well, for 12 + 11.7 + 11.28= 34.98.

The answer is 34.98 yds². Good luck :)

Answer:

45.36 square inches

Step-by-step explanation:

Given the following

Surface area of a triangular prism  = 18 square inches

If it is enlarged by a scale factor of 2.52, the area of the enlarged solid is expressed as;

Area of enlarged solid = area of original sold * scale factor

Area of enlarged solid = 18 * 2.52

Area of enlarged solid = 45.36 square inches

hence the surface area of a similar solid that has been enlarged by a scale factor of 2.52 is 45.36 square inches

Answer:45.36 square inches

Step-by-step explanation:

How far is the campsite from their car?

4 miles

(0,4)

Write an equation that describes the relationship between d and h.

d = 3h + 4

After how many hours will the hikers be 16 miles from their car?

16 = 3h + 4

12 = 3h

4 = h

After 4 hours

Answer:

12.16

Step-by-step explanation:

1:Reduce the fraction 100 38 ​ to lowest terms by extracting and canceling out

2:Express 50/19 ​ ×32 as a single fraction.

3:Multiply 19 and 32 to get 608.

4:Reduce the fraction 608/50 ​ to lowest terms by extracting and canceling out 2.

5:304/25=(12.16).

Answer:

x≥11

Step-by-step explanation:

The information provided indicates that you have to hike minimum 11 miles each day to be able to complete the trip in the time you have and this means that the number of miles you hike each day has to be greater than or equal to 11 and this can be expressed as:

x≥11, where:

x is the number of miles you must hike each day.

Answer:

24

Step-by-step explanation:

Multiples of 16 are [tex]16,32,48,64,80,...[/tex]

Find product of each of the multiple of 16 until a number is obtained, the product of whose digits is a multiple of 12.

[tex]16=1(6)=6\\32=3(2)=6\\48=4(8)=32\\64=6(4)=24[/tex]

Here, 24 is a multiple of 12.

So,

24 is the least positive integer such that it is a multiple of 16 and the product of its digits is a multiple of 12.

Answer:

v=-16

Step-by-step explanation:

-2=2+v/4

(we know that 2+-4=-2 so we can see if that works)

(4*-4=-16)

2+-16/4=-2

(-16/4=-4)

2+-4=-2

we can easily solve this one by splitting theiddle term

x2 - 9x -10

x2 -10x + x - 10

x(x - 10) 1( x - 10)

(x + 1) (x-10)

x = -1 or 10
