Give a real world example of a sample that was used to make a prediction about a population

olchik [2.2K]

Answer:

Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

Choose the equation of the line that has a slope of 2/3 and y-intercept of -4.

pentagon [3]

The general equation for a straight line is $y=mx+b$ , where m is the slope, and b is the y-intercept. Plugging in numbers, your equation will be $y=\frac{2}{3}x-4$ .

PLEASE HELP AS SOON AS POSSIBLE PLEASE SHOW WORK AND HELP ME UNDERSTAND ASAP WILL GIVE BRAINLIEST

Ivenika [448]

Answer:

y = 2x + 8

Step-by-step explanation:

Recall that two parallel lines have the same slope.

Thus, if we begin with y = 2x - 4, we know that this new line through (-1, 6) will also have slope 2.

Starting from the slope-intercept form y = mx + b, we substitute 2 for m, -1 for x and 6 for y:

6 = 2(-1) + b

and solve for the new y-intercept, b:

6 = -2 + b, or

b = 8

Then the new line has the equation y = 2x + 8

Four roommates want to split the price of a computer. How much will each roommate pay? Write an equation and solve it by using t

The division is one of the four fundamental arithmetic operations. The amount that is needed to be paid by each friend is $74.75.

<h3>What is Division?</h3>

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

As it is given that the total cost of the computer is $299, it is needed to be split between four friends. Therefore, the price will be paid by the four friends equally which can be written as,

$\text{Amount paid by each friend}=\dfrac{\text{Total cost of computer}}{\text{Number of friends}}\\\\\\\text{Amount paid by each friend}=\dfrac{\$299}{4} = \$74.75$

Thus, the amount that is needed to be paid by each friend is $74.75.
