Multiplication and distributive property are your friends for this problen

Before doing anything, we must convert the unit of feet into the unit of inches so that all the units match. You cannot multiply apples by oranges!

Since 1 ft = 12 inches, then a 17 foot piece of lumber is 204 inches long.

12(17) = 204

Now, we can write an equation.

Let x = the amount of logs that can be cut from the lumber

204 = x(18)

204/18 = x(18)/18

x = 11.333333.....

You do not want .333333.... of a log, so you can cut 11 logs max.

You will then have that .333333333.... inches of lumber left.

Write an equation in slope-intercept form of the line that passes through (7, 2) and (2, 12)
Anika [276]

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope, b is the y-intercept (when x=0).

the slope is the ratio y/x indicating how much y changes, when x changes for a certain amount of units when going from one point to another.

going from (7, 2) to (2, 12) :

x changes by -5 (from 7 to 2), y changes by +10 (from 2 to 12).

so, the slope is 10/-5 = -2

therefore, we have already

y = -2x + b

we get b by using the coordinates of one of the points as x and y. e.g. (7, 2)

2 = -2×7 + b = -14 + b

16 = b

so, the full line equation is

y = -2x + 16

Exhibit 6-2 the weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 poun
Evgen [1.6K]
The question is asking for the lower bound of the 95% two tailed Confidence interval of the normally distributed population.

95% C.I. is given by 200 + or - 1.96(25) = 200 + or - 49 = (151, 249)
Therefore, the minimum weight of the middle 95% of players is 151 pounds.

The lines shown below are parallel.if the green line has a slope of -1,what is the slope of the red line?
vova2212 [387]

Answer:

-1

Step-by-step explanation:

If a line is parallel on a graph, then that means that they will descend/climb at the same rate. Therefore, the slope of this line is also -1.

Hope this helped!
