One winter day, the outside temperature, y, was never below −1°. The inside of a car was always warmer than the temperature outs

Response:

Option B.

Step-by-step breakdown:

The general equation for the best fit line is

where a indicates the slope and b the y-intercept.

Utilizing a graphing calculator yields a=-4.54762 and b=43.7143. Hence, the equation for the best fit line can be represented as

Here,

Note: Alternatively, you can apply the following formula to compute the slope.

Accordingly, the correct choice is B.

To determine the result of multiplying 0.003 by 10, you will simply multiply as such. A straightforward method is to shift the decimal point one place to the right (it would shift two places for multiplying by 100, and three for 1000, etc.). The same rule applies when dividing; just ensure to move left instead.

Hence, the result is 0.03.

Answer:

1.5 miles per hour

Step-by-step explanation:

Multiply 132 feet by 60 seconds to get 7920. Subtract 5280, the number of feet in a mile, leaving you with 1 mile and an additional 2640 feet, which amounts to half a mile.

Answer:

Upon solving for y, we find:

By substitution, we have:

Thus, we arrive at:

And for x, we determine:

This gives us a length of 76 and a width of 12.5.

Step-by-step explanation:

We are dealing with a rectangle. The formula for the perimeter is:

Here, x denotes the length and y the width. The following conditions can be established:

Substituting these values yields:

When we solve for y, we find:

By substitution, we obtain:

Thus, we conclude:

The length is found to be 76, while the width measures 12.5.
