What is the correct solution to 1/2(x+18)=4(2x-6)-9x

Mathematics

denis-greek [22]3 years ago

Answer:

x = 22

Step-by-step explanation:

I interpreted your problem as:

\frac{1}{2} (x+18) = 4(2x-6)-9x

I simplified the problem to:

\frac{1}{2} x+9 = 8x-24-9x

I combined like terms:

\frac{1}{2} x+9 = -x-24

I moved all x to one side and all other constants to the other:

\frac{3}{2} x = -33

I divided by 3/2 (1.5) on both sides to isolate x:

x = 22

Hope it helps! (:

Find AB when given angle B 64 degress angle C 75 degrese and side a 19
jeka94

Answer:

about 28

Step-by-step explanation:

you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)

AB = 19* (sin 75/ sin ( 180 -75-64) )

AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...

A sample of 32 observations is taken from an infinite population. The sampling distribution of a.is approximately normal because
Vanyuwa [196]

Answer:

a.is approximately normal because of the central limit theorem.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

Sample limit of 32 > 30, so the distribution is approximately normal because of the central limit theorem, and the correct answer is given by option a.
