Answer:

0.284

Step-by-step explanation:

To carry out this calculation, we begin by describing the sampling distribution of the sample proportion.

The sample size is n = 50 and the population proportion of teachers who made an apparel purchase is 0.56.

Shape: Because np = (50)(0.56) = 28 and n(1 – p) = (50)(0.44) = 22 are both at least 10, the shape of the sampling distribution of the sample proportion is approximately Normal.

How does water help living things? Check all that apply.

Triss [41]

Hey there!

The answers would be

A. reproduction
B. temperature regulation
C. oxygen transportation
D. heat absorption
E. nutrient reproduction or ALL OF THE ABOVE

Water keeps all of your organs and cells functioning properly including the reproductive cells (egg, sperm) and reproductive organs (brain, ovaries, uterus, testes, thyroid). It also naturally flushes out toxins in the body. For men, semen production and semen volume can be reduced by not drinking enough water.

Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells.

Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.

Living organisms need water to survive. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.

Hope this helps!

Pls help i dont care how u do it jast pls help me

Airida [17]

Answer:

1. 35 boys and 28 girls

2. 42 long-sleeved shirts

3. 40 total outfits

Step-by-step explanation:

1.

Ratio of Boys to Girls is 5 is to 4, that means that there are "5" parts boys and "4" parts girls. So that makes:

5 + 4 = 9 parts in total

Total there are 63 kids, so each part would be:

63/9 = 7 kids per part

Now,

5 part are boys so 5 * 7 = 35 boys

and

4 parts are girls so 4 * 7 = 28 girls

2.

Long Sleeved Shirts = 60% of the total

Total is 70

So, we basically need 60% of 70

First, we want to convert 60% to decimal. We divide by 100, that's it! So:

60/100 = 0.6

Now to get the number we simply multiply the decimal of 60% we got, which is 0.6 with the total, which is 70. Thus,

0.6 * 70 = 42

Thus, there are 42 long-sleeved shirts

3.

Lily has 30 dress, WHICH ARE 75% of the total outfits she has.

First of all, what is 75% in decimal?

We divide by 100:

75/100 = 0.75

We can now write:

30 is 0.75 times the total

Right?

Which number's 75% (or 0.75) is 30? This is what we need to figure out!

0.75 * which number would give us 30?

We have to simply divide 30 with 0.75 to get total number of outfits:

30/0.75 = 40 total outfits
