A third grade class has 16 girls and 15 boys a fourth grade class has 18 boys and 15 girls when picking for PE captains will mak

Mkey [24]

Answer:

$\dfrac{90}{341}$

Step-by-step explanation:

3rd grade:

Number of girls = 16

Number of boys = 15

Total number of students = 31

4th grade:

Number of girls = 15

Number of boys = 18

Total number of students = 33

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Probability of picking a boy from 3rd grade, $P_{1} = \dfrac{15}{31} ..... (1)$

Probability of picking a boy from 4th grade, $P_{2} = \dfrac{18}{33} ..... (2)$

These are two independent events of picking a boy from 3rd grade and 4th grade.

So, probability the captain chooses 2 boys in the first pick can be found by multiplying (1) and (2) above.

$P = P_{1} \times P_{2}\\\Rightarrow \dfrac{15}{31} \times \dfrac{18}{33}\\\Rightarrow \dfrac{90}{341}$

Based on the spreadsheet below, which of the following is a true statement? A 2-column spreadsheet showing Cash Inflows and Cash

timama [110]

The net cash flow which is the excess of inflows over outflows is $110, hence, the correct option is:

c. The net cash flow is positive

What are inflows and outflows?

The inflows are cash received by the individual which increase cash balance where cash outflows are expenses, which reduce the balance of cash.

Based on the above, the total inflows of the individual is computed thus:

total inflows=disposable income+ interest on deposit +income from investment

total inflows=1600+0+0

total inflows=$1,600

Total outflows are as well summed as below:

total outflows=rent +utilities +cable and telephone +groceries+ car expenses+ recreation+ insurance + miscellaneous

total outflows=575+120+80+320+150+80+115+50

total outflows=$1,490

net cash flow=total inflows-total outflows

net cash flow=$1,600-$1,490

net cash flow=$110

An artist makes a cube-shaped sculpture.

ratelena [41]

All the sides of a cube are always the same.
Area = 12 in x 12 in = 144 in^2
Volume = 12 in x 12 in x 12 in = 1728 in^3

Hence, you can confirm all the side of this cube is 12 in.
