Step 1: Seperate the mixed numbers from their fractions.
$- 5 - \frac{5}{7} + 8 - 3 - \frac{2}{7}$
Step 2: Add -5 and -3. The sum of that is -8, thus we have an additive inverse. 8 and -8 cancel out, becoming a 0.
$- 8 - \frac{5}{7} + 8 - \frac{2}{7} = - \frac{5}{7} - \frac{2}{7}$
$\frac{ - 5 - 2}{7} = \frac{ - 7}{7} = - 1$
Therefore, the answer is -1

Given that P(E) = 0.38, P(F) = 0.38, and P(E ∩ F) = 0.12. Find P(E ∪ F, how do I work this out?

natulia [17]

Answer: The value of P(E∪F) = 0.64.

Step-by-step explanation:

Since we have given that

P(E) = 0.38

P(F) = 0.38

P(E∩F) = 0.12

So, we need to find the P(E∪F).

As we know the formula for the sets.

$P(E\cup F)=P(E)+P(F)-P(E\cap F)\\\\P(E\cup F)=0.38+0.38-0.12=0.64\\\\P(E\cup F)=0.64$

Hence,the value of P(E∪F) = 0.64.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each

Ostrovityanka [42]

Answer:

There were 7 small boxes and 14 large boxes shipped.

Step-by-step explanation:

This problem may be solved by a system of equations:

I am going to say that:

x is the number of small boxes used

y is the number of large boxes used

There were twice as many large boxes shipped as small boxes shipped

This means that $y = 2x$

Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.

This means that $45x + 80y = 1435$

So we have to solve the following system:

$y = 2x$

$45x + 80y = 1435$

$45x + 80(2x) = 1435$

$205x = 1435$

$x = \frac{1435}{205}$

$x = 7$

$y = 2x = 2(7) = 14$

There were 7 small boxes and 14 large boxes shipped.
