Which table represents the equation y = -2x + 17?
Alexeev081 [22]
<h3>Answer: Choice A</h3>

Explanation:

Each table has x = 10 in it. Plug this value into the given equation.

y = -2x+17

y = -2*10+17

y = -20+17

y = -3

The input x = 10 leads to the output y = -3. Table A shows this in the middle-most row. So that's why choice A is the answer. The other tables have x = 10 lead to y values that aren't -3 (eg: choice D has x = 10 lead to y = 12), so we can rule them out.

Find the value of x that makes m || n
ch4aika [34]

Answer:

x=133

Step-by-step explanation:

Given: m║n

This means that 147 and x+14 are <em>alternate exterior angles</em>. This also means that they are equivalent. We can use this information to set up an equation:

x+14=147

Subtract 14 from both sides to isolate x

x=133

You have been asked to find the inverse of f(x) = 3+ V2 - 1. What would your first step be?
Aleonysh [2.5K]

Answer:

Add 1 to both sides of the equation.

Subtract 3 from both sides of the equation.

Step-by-step explanation:

The inverse of a function refers to that function that tends to undo another function.

If we intend to find the inverse of the function, f(x) = 3+ V2 - 1, we have to first add 1 to both sides of the equation and subsequently subtract 3 from both sides of the equation before taking the square root of both sides to obtain the inverse function.

In Spring 2017, data was collected from a random selection of STA 2023 students. One of the questions asked how many hours they
Arte-miy333 [17]

Answer: 0.22

Step-by-step explanation:

We know that the best point estimate for the difference between two population mean is the difference between their sample means.

Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.

Let A denotes the population of upperclassmen and B denotes the population of underclassmen .

\overline{x}_A=0.12

\overline{x}_B=0.34

Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

\overline{x}_B-\overline{x}_A=0.34-0.12=0.22

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22

Use linear regression to find a
Inessa [10]

A function that fits the following points (0,5), (2,-13) is y = 9x + 5

<h3>Equation of a line</h3>

The equation of a line in slope-intercept form is expressed as;

y =mx +b

where;

m is the slope

b is the intercept

Given the following coordinates (0,5), (2,-13)

Slope = -13-5/2-0
Slope = -18/-2

Slope = 9

Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5
