MatroZZZ [7]4 years ago

So for this i would always drop the decimal from the number so it will be 796 ÷ 5 which would be 159.2 so the was two numbers in the original  problem over from the decimal would be put back in the answer. so you would put the decimal in over two times so the answer will be   1.592

A cube has an edge length of 5 inches, and a side length of 15. What is the volume?
notsponge [240]
The formula of the volume of a cube:
Volume = s^3

Given that the side length is 15. So we can easily get the volume by substituting it to the value of the side.

Volume = s^3
Volume = 15^3
Volume = 3,375 in^3

So the volume given the side length of 15 is equal to 3,375 in^3.

Which is the simplified form of the expression<br> 3<br> 2<br> 21 12<br> x y12<br> 24
MakcuM [25]

Answer:

the second option is solution

Step-by-step explanation:

exponents inside parentheses get multiplied by exponents outside them

so first:  x^-9y^6 divided by x^12y^18

next, when dividing like terms, keep variable and subtract their exponents

-9 - 12 = -21

6 - 18 = -12

Don't leave negative exponents as answer, simplify by putting them into the denominator (where the exponents will now become positive) with 1 as numerator

Bad gums may mean a bad heart. Researchers discovered that 79% of people who have suffered a heart attack had periodontal diseas
zysi [14]

Answer:

(A) 0.297

(B) 0.595

Step-by-step explanation:

Let,

H = a person who suffered from a heart attack

G = a person has the periodontal disease.

Given:

P (G|H) = 0.79, P(G|H') = 0.33 and P (H) = 0.15

Compute the probability that a person has the periodontal disease as follows:

P(G)=P(G|H)P(H)+P(G|H')P(H')\\=P(G|H)P(H)+P(G|H')(1-P(H))\\=(0.79\times0.15)+(0.33\times(1-0.15))\\=0.399

(A)

The probability that a person had periodontal disease, what is the probability that he or she will have a heart attack is:

P(H|G)=\frac{P(G|H)P(H)}{P(G)}\\=\frac{0.79\times0.15}{0.399} \\=0.29699\\\approx0.297

Thus, the probability that a person had periodontal disease, what is the probability that he or she will have a heart attack is 0.297.

(B)

Now if the probability of a person having a heart attack is, P (H) = 0.38.

Compute the probability that a person has the periodontal disease as follows:

P(G)=P(G|H)P(H)+P(G|H')P(H')\\=P(G|H)P(H)+P(G|H')(1-P(H))\\=(0.79\times0.38)+(0.33\times(1-0.38))\\=0.5048

Compute the probability of a person having a heart attack given that he or she has the disease:

P(H|G)=\frac{P(G|H)P(H)}{P(G)}\\=\frac{0.79\times0.38}{0.5048}\\ =0.59469\\\approx0.595

The probability of a person having a heart attack given that he or she has the disease is 0.595.

The measure of an angle is nine times the measure of its complement. find the measure of each angle.
andrew11 [14]
Two angles are complementary when they add up to 90 degrees<span> 

</span><span>smaller angle = x
</span><span>larger angle = 9x
</span>
x + 9x = 90
10x = 90
x = 90/10
x = 9°  ← smaller angle

larger angle = 9x = 9 * 9 = 81°
