If your wondering how to do triple number multiplication then
If you have three numbers like 2x3x4 you'd multiply 2x3=6 then you'd multiply 6x4 and get 24... If you need to know something else I need more info.

Viefleur [7K]

Answer:

52 should be the answer

Step-by-step explanation:

first, love the parathesis. subtract 7-2

second 3 raised to the second power

third times 3 raised to the third power by 5 the answer a few u substrates 7-2

fourth 14 divide 2

finally I would add (14/2) 7 + 45 (which is 9 times 5)

read through it carefully by the end if the problem, you should have 52 as the ans

A market researcher for a provider of music player accessories wants to know the proportion of customers who own cars to assess

Luba_88 [7]

Answer:

Step-by-step explanation:

Hello!

To evaluate the market for a new car charger, a market researcher surveyed 600 customers and found out that 73% of them own a car.

The parameter of interest is the population proportion and the study variable is "the number of customers that own a car out of 600".

Using the Central Limit Theorem you can approximate the distribution of the sampling proportion to normal:

p'≈N(p; $\frac{p(1-p)}{n}$ )

Where p' is the sample proportion

p is the population proportion and the mean of the distribution

$\frac{p(1-p)}{n}$ is the variance of the distribution

Then de standard deviation of the samplig proportion distribution is $\sqrt{\frac{p(1-p)}{n}}$

You can estimate it using the sample proportion:

$\sqrt{\frac{p'(1-p')}{n}} = \sqrt{\frac{0.73*0.27}{600} }=0.0181$

Using the same sample proportion but a sample size of n=150, the estimated standard deviation is:

$\sqrt{\frac{p'(1-p')}{n}} = \sqrt{\frac{0.73*0.27}{150} }=0.0362$

I hope it helps!

You have to find the cube root of 27.
A same number when multiplied 3 times by itself will give the cube.
3√27 = 3 x 3 x 3

So the answer is 3

As θ increases from -pi/2 to 0 radians, the value of cos θ will.

GrogVix [38]

Answer:

4) Increase from 0 to 1

Step-by-step explanation:

We have to analyze the value of cos(Ф) from -π/2 to 0. This can be done if we simplify evaluate the value of cos(Ф) at these two extreme.

$cos(-\frac{\pi}{2}) = cos(\frac{\pi}{2} )=cos(90)=0\\\\ cos(0)=1$

This shows that value of cos(Ф) is 0 at -π/2 or -90 degrees and increased to 0 at 0 degrees.

This answer can be validated if you visualize the graph of cos function. Cos function has a peak at 0 degrees, i.e. a value equal to 1. On right and left side of 0 degrees, the curve starts falling down and eventually touches the horizontal axis at 90 degrees and -90 degrees. This is shown in the graph attached below:
