Ah, not quite. The formula for this, I believe, is 2(wl+hl+hw)
Meaning your equation would look like: 2(5*12+8*12+8*5)
Basically, your final answer is 392 for surface area, I believe.

Well first you would do 2(lw+hl+wh). Which is 2(12(5)+12(8)+8(5). If you do the math that would be 2(60+96+40). Then add to get 186. Multiply by 2 to get 372. I hope this wasn't confusing.

Simplify the following expression please solve correctly<br> −12^12 ^2 / 3^ 5 ^5

nikdorinn [45]

The simplified expression is $-\frac{48}{x^{3} y^{3}}$

Explanation:

The given expression is $\frac{-12x^{2}12y^{2} }{3x^{5} y^{5} }$

Let us simplify the expression.

Multiplying the numbers in the numerator, we have,

$\frac{-144 x^{2} y^{2}}{3 x^{5} y^{5}}$

Dividing the term 144 by 3, which results in 48.

Thus, we have,

$\frac{-48 x^{2} y^{2}}{x^{5} y^{5}}$

Applying the fraction rule $\frac{-a}{b}=-\frac{a}{b}$ , we get,

$-\frac{48 x^{2} y^{2}}{x^{5} y^{5}}$

Applying the exponent rule $\frac{x^{a}}{x^{b}}=\frac{1}{x^{b-a}}$ , we have,

$-\frac{48}{x^{3} y^{3}}$

Thus, the simplified expression is $-\frac{48}{x^{3} y^{3}}$

Assuming that workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year, find the probabi

lord [1]

Answer:

The probability is $P(\$20,000 < X < \$35,000) = 0.6$

Step-by-step explanation:

From the question we are told that

Workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year

Generally the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000 is mathematically represented as

$P(\$20,000 < X \$35,000) = \frac{ 35000 - 20000}{ 40000 - 150000}$

=> $P(\$20,000 < X < \$35,000) = 0.6$

A repeated-measures study and an independent-measures study both produce a t statistic with df = 20. The repeated-measures study

Y_Kistochka [10]

Answer:

B. False

Step-by-step explanation:

We have that both studies have the same production for what the first part of the statement mentions.

"A repeated-measures study and an independent-measures study both produces a t statistic with df = 20"

And they ask us if it is false or true, if one produces more than the other.

Starting from the first statement, the second statement is false because they produce the same, therefore they will be the same subjects.
