Answer:

Option D: The area will be multiplied by 16.

Step-by-step explanation:

Given that the area of the figure is 13 sq. in.

Let is say the figure is of dimensions: a & b.

Therefore, a.b = 13 sq. in

When each of the dimension is multiplied by 4, the dimensions would become 4a and 4b.

Therefore, the area would be: 4a . 4b = 16 a . b = 16(13) sq. in.

Hence, the area is multiplied by 16.

Answer:

3

Explanation:

4 is half of 8 on the right side, so that means X has to be half of 6, so it’s 3. Also, it couldn’t be 2 because it is too big, and it can’t be 4 because it isn’t the same length as the other 4, so it’s 3

Sales prices of baseball cards from the 1960s are known topossess a skewed-right distribution with a mean sale price of $5.25and

Serga [27]

Answer:

c. Skewed-right with a mean of $5.25 and a standard error of$0.28

Step-by-step explanation:

As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.

Now, We know that if standard deviation = σ

then, standard error = $\frac{\sigma}{\sqrt{n}}$

As, we have standard deviation = $2.80

then standard error will be $\frac{2.80}{\sqrt{100}}$

⇒ Standard error = $0.28

Hence, Option (c) is the correct option.
