If a lineman can install 12 insulators in 183/4 hours, how many insulators should he be able to install in 281/8 hours?

To determine the unit rate, divide 1.19 by 12, which gives the cost per ounce. 1.19/12 =.099 per ounce. Since this involves currency, round your answer to two decimal places unless stated otherwise. Rounding.099 results in $0.10 per ounce.

Answer:

A: With each additional procrastination day, the expected grade drops by 3.64 points.

Step-by-step explanation:

The slope of a Regression Line

A linear equation can be expressed in slope-intercept form:

y = mx + b

Here, m represents the slope and b indicates the y-intercept.

The slope reveals the rate and direction of change in the graph as x varies.

<pif m="" is="" positive="" increases="" in="" x="" result="" y.="">

If m is negative, increases in x lead to decreases in y.

<pthe regression="" equation="" is:="">

ŷ = –3.64x + 96.5

Where:

x = number of procrastination days

ŷ = anticipated grade

<pthus the="" slope="" is="" m="-3.64." this="" indicates:="">

A: With each additional procrastination day, the expected grade drops by 3.64 points.

We understand that a rectangle has been altered into the one shown in Figure 1 using this rule:



It is known that the origin is the center of rotation and two rules apply to perform a rotation of 90 degrees, namely:

1. Clockwise

The rule to convert a point in this case is:



This rule has already been implemented to create the image, so we need to reverse the outcome using this formula, hence:



2. Counterclockwise

Applying the same concept as before but with new rules for the scenario:



Reversing the outcome gives us:

12x2= $24
24 + 28 + 45 = $97

Thus, $97 represents the total amount (100%)

Calculating 100% - 30% gives 70% (with 30% discount)
(noting that 70% equals 70/100 or 0.7)

Therefore, 97 x 0.7 = $67.90
