Answer:
u=1/2
Step-by-step explanation:
-3(-6u+6)-3u=5(u-2)-3
18u-18-3u=5u-10-3
15u-18=5u-13
15u-5u-18=-13
10u-18=-13
10u=-13+18
10u=5
u=5/10
simplify
u=1/2
Answer:
95%.
Step-by-step explanation:
We have been given that the lifetimes of light bulbs of a particular type are normally distributed with a mean of 370 hours and a standard deviation of 7 hours.
We are asked to find the percentage of the bulbs whose lifetimes lie within 2 standard deviations to either side of the mean using empirical rule.
The empirical rule (68-95-99.7) states that approximately 68% of data points lie within 1 standard deviation of mean and 95% of data points lie within two standard deviation of mean. 99.7% of data points lie within three standard deviation of mean.
Therefore, approximately 95% of data points lie within two standard deviation of mean.
The quadratic equation that would model this scenario is
Let us take the side of the square = x
Area of the square = x²
Length of the rectangular garden = 2x
Width of the rectangular garden = x-16
So, the area of the new vegetable garden = length*width
Area of the new or rectangular vegetable garden = 2x(x-16)
<h3>What is a quadratic equation?</h3>
The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by 
coefficient 
non-zero.
Since it is given that
Area of square garden = area of the rectangular garden
Thus, the quadratic equation that would model this scenario is

Answer:
Convert each fraction to its percentage form:
= 36 / 40
= 90%
= 1/3
= 33.3%
= 70/100
= 70%
= 1 / 8
= 12.5%
Looking at the percentages:
= 36 / 40 is closest to 1.
= 1/3 <u>and</u> 70/100 are closest to one half which is 50%
= 1/8 is closest to 0.
