1/3(6x+24)-20 < -1/2(6x-36)

Hi there!
The question here gives us an inequality, and it tells us to solve for x. 
\frac{1}{3} (6x+24)-20 \ \textless \  - \frac{1}{2} (6x-36)
First, use the distributive property to simplify both sides of the equation.
2x+8-20\ \textless \ -3x+18
Now, on the left side of the inequality, combine like terms.
2x-12\ \textless \ -3x+18
Add 12 to both sides.
2x\ \textless \ -3x+30
Add 3x to both sides.
5x\ \textless \ 30
Divide 5 from both sides.
x\ \textless \ 6
Therefore, the solution to the inequality is anything less than 6, or x < 6. Hope this helped!

Use Pythagorean theorem!!! Will give b !!
aliina [53]

Answer:

The last one

Step-by-step explanation:

Hey There!

The Pythagorean Theorem states that

the two legs squared added together equal the hypotenuse square

we are given the two legs so to find the missing side we square them, then add them together

1^2=1\\3^2=9\\9+1=10

the missing side length equals

\sqrt{10}

hope this helps!

A set of city temperatures in April are normally distributed with a mean of 19.7 degrees Celsius and a standard deviation of 2 d
Sati [7]

Answer:

19.77% of average city temperatures are higher than that of Cairo

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 question, we have that:

\mu = 19.7, \sigma = 2

What percentage of average city temperatures are higher than that of Cairo?

This is 1 subtracted by the pvalue of Z when X = 21.4.

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

Z = \frac{21.4 - 19.7}{2}

Z = 0.85

Z = 0.85 has a pvalue of 0.8023

1 - 0.8023 = 0.1977

19.77% of average city temperatures are higher than that of Cairo
