Answer:

a is the ans;8/15

Step-by-step explanation:

6 times 7 to the second power

Travka [436]

Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6.

7 to the second power simply means 7x7.

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer.

6 x 49 = 294

I hope this helps answer your question! Have a great day!

The scale drawing of a rectangular room will be enlarged by a scale factor of 4 to create the actual room. The actual area of th

bearhunter [10]

Answer:

The expression is equal to $\frac{150}{4^{2}}$

The area of the scale drawing is $9.375\ ft^{2}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

let

z------> the scale factor

x------> the area of the actual room

y-----> the area of the scale drawing

so

$z^{2}=\frac{x}{y}$

we have

$z=4$

$x=150\ ft^{2}$

substitute and solve for y

$4^{2}=\frac{150}{y}$

$y=\frac{150}{4^{2}}=9.375\ ft^{2}$

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

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.
