16ft= 192 in
8ft= 96 in

192/36= 96/16 = 6

Your drawing is 1/6 of the actual billboard

Eli has bought a shirt and a pair of pants for a total of 600 kr. Simin bought four of those shirts and two of those pants, and

fgiga [73]

Answer:

Step-by-step explanation:

let the price of one shirt be x and one pant be y

Eli--> x+y=600------eq1

Simin-->4x+2y=1500-----eq2

Solve both the equations

multiply eq1 x 4= 4x+4y=2400

now subtract ew2 from 1

you will get y=450 and x=150

so price of one shirt=150 kr

According to the Central Limit Theorem, which statements(s) are TRUE. There may be more than 1 correct answer. A. An increase in

Liono4ka [1.6K]

Answer:

Options A, B and C are correct.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes 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.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

From the Central Limit Theorem, we have that:

The larger the sample size, the closer to the normal distribution the distribution of sample means is.

No matter the sample size, the mean is the same.

The larger the sample size, the smaller the standard deviation.

The smaller the sample size, the larger the standard deviation.

So the correct options are:

A, B, C

Which of the following is an example of rigid transformations?

Liula [17]

Answer:

Moving the glass from one place to other is rigid transformation.

Step-by-step explanation:

The rigid transformation includes rotation, translation, reflection or their combination.

So, Moving the glass from one place to other place is translation. It is example of rigid transformation.

Now, cutting a piece of bread is not rotation or translation or reflection. So, it is NOT rigid transformation.

Squeezing the cherry is not rotation or translation or reflection. So, it is too NOT rigid transformation.
