A construction crew is lengthening a road. The road started with a length of 59 miles, and the crew is adding 2 miles to the roa
Illusion [34]
The answer is L = 59 + 2(d). If we plug in our numbers, we will get L = 59 + 2(32). 2*32 is 64, and if you add 59 you get 123 miles.

This isn’t apart of the question, but 59 would be the y-intercept. 2 miles per day (2/1) is the slope.

in a classroom training student has to create a triangle pyramid using various items. Each group then used measurement to determ
balandron [24]

The formula for the volume of pyramid is,

V=\frac{Bh}{3}

Here, B is base area and height of pyramid.

The volume expression for group 4 is,

V=\frac{1}{3}\cdot(\frac{8\cdot4}{2})\cdot9

Here, expression,

\frac{8\cdot4}{2}

represents the base area and 9 represent the height of pyramid.

So height of the pyramid created by group 4 is 9.

If the average weight for cats is 12
Mariulka [41]

Answer:

3 standard deviations

from the mean is 6 pounds to 18 pounds.

Step-by-step explanation:

The above question is solved using empirical rule

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

From the above question

μ = 12 pounds

σ = 2 pounds

Hence:.

3 standard deviations from the mean is calculated as

μ - 3σ

[12 - 3(2)] pounds

=( 12 - 6) pounds

= 6 pounds

μ + 3σ

[12 + 3(2)] pounds

=( 12 + 6) pounds

= 18 pounds

Hence,3 standard deviations

from the mean is 6 pounds to 18 pounds.
