Answer:

7/10

Step-by-step explanation:

Set up an equation to solve the problem

1/5 = 9/10 - x

Lets make them all have a common denominator

1/5 = 2/10

Subtract the 9/10

2/10 = 9/10 - x

- 9/10 - 9/10

-7/10 = -x

Since -x equals -7/10, that means positive x equals 7/10

The answer then comes out to:

x = 7/10

Jordans have a rectangular garden. want to build a diagonal pathway across he garden. the length of pathway is 90 ft. width of g

blondinia [14]

So we see the pythagorean theorem
a^2+b^2=c^2
diagonal=c
width=a or b, pick one
width=a
legnth=b
width is 5 times more than 2 times legnth of garden
w=5(2legnth)
this doesn't make sense since the legnth is normally longer than the width, but we'll stick with that
w=5(2l)
w=10l
a=10b
(10b)^2+b^2=90^2
100b^2+b^2=8100
101b^2=8100
divide by 101
b^2=80.198 aprox 80.2
square root
8.95533
legnth of garden =8.96
to find width subsitue
w=10l
w=89.56

legnth=8.96
width=89.56

What is the value of x in the equation 1/2x - 3/4 = 3/8 - 5/8

Kitty [74]

The answer

x = 1

step by step

$\frac{1}{2} x - \frac{3}{4} = \frac{3}{8} - \frac{5}{8} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{3}{4} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{6}{8} \\ \frac{1}{2}x = \frac{4}{8} \\ \frac{1}{2} x = \frac{1}{2} \\ x = 1$

In a randomly selected sample of 1169 men ages 35–44, the mean total cholesterol level was 210 milligrams per deciliter with a s

Aneli [31]

Answer:

The highest total cholesterol level a man in this 35–44 age group can have and be in the lowest 10% is 160.59 milligrams per deciliter.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 210, \sigma = 38.6$
