Answer:

$y=x$

Step-by-step explanation:

From the graph of the line you can see that this line passes through the points (0,0) and (1,1).

The equation of the line that passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1).$

Therefore, the equation of the graphed line is

$y-0=\dfrac{1-0}{1-0}(x-0),\\ \\y=x.$

ASAP HELP: If a sample proportion is 0.55, which range of possible values best describes an estimate for the population paramete

iris [78.8K]

Answer:

B.(0.4,0.7)

Step-by-step explanation:

We are given that

Sample proportion

$\hat{p}=0.55$

We have to find the range of possible values which describes best an estimate for the population parameter.

Estimate for the population parameter

$\hat{p}\pm Z(SE)$

A.(0.55,0.6)

Difference between 0.55 and 0.55=0

Difference between 0.55 and 0.6=0.05

Difference between 0.55 and 0.55 is not equal to difference between 0.55 and 0.6.

Hence, option A is wrong.

B.(0.4,0.7)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.7=0.15

Difference between 0.55 and 0.4 is equal to difference between 0.55 and 0.7.

Hence, option B is correct.

C. (0.4,0.69)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.69=0.14

Difference between 0.55 and 0.4 is not equal to difference between 0.55 and 0.69.

Hence, option C is not correct.

D.(0.5,0.59)

Difference between 0.55 and 0.5=0.05

Difference between 0.55 and 0.59=0.04

Difference between 0.55 and 0.5 is not equal to difference between 0.55 and 0.59.

Hence, option D is not correct.

Which scenario could be represented by the given graph?

Alex Ar [27]

Answer:

Choice D

Step-by-step explanation:

The distance increases at a steady rate from time = 0 to time = 1.

Then no progress is made between time = 1 and time = 2.

Then the distance increases at the same steady rate from time =2 to time = 3.

Finally, no progress is made between time = 3 and the end of the graph.

Eliminate Choices A, B and C immediately, because none of these scenarios involves a stop and wait.

That leaves only Choice D as a reasonable verbal description of what's happening here.

Convert into slope intercept form?

Alexeev081 [22]

<h3>Answer:</h3>

y = 2x + 5

<h3>Step-by-step explanation:</h3>

<u>Definitions</u>:

Slope Intercept form; y = mx + b

m = slope

b = y intercept

Step 1: Since the slope is given plug it into y = mx

y = 2x + b

Step 2: Plug a points' x and y into their corresponding spots to solve for b

(33) = 2(14) + b

Simplify and solve

33 = 28 + b

-28 -28

5 = b

Plug both your slope in and your y intercept into y = mx + b

y = 2x + 5
