Answer:

Emily: \frac{20.99}{83.90}

Ally: \frac{28.47}{83.90}

Rosalie: \frac{19.47}{83.90}

Rosaline: \frac{14.97}{83.90}

Step-by-step explanation:

We know that the total is 83.90. Each person's fraction will be \frac{person}{83.90}.

suppose you randomly choose an integer n between 1 to 5, and then draw a circle with a radius of n centimetres. What is the expe
const2013 [10]
The set of possible integers is 1, 2, 3, 4, and 5.

The area of a circle with radius of n centimeters = π(n)^2.

So, the set of possible values are:

n       area = π(n^2)

1       π

2       4π

3       9π

4       16π

5       25π

And the expected value of the area may be determined as the mean (average) of the five possible areas:

expected value of the area = [ π+ 4π + 9π + 16π + 25π] / 5 = 11π ≈ 34.5575, which rounded to the nearest hundreth is 34.56

Answer: 34.56

I tried to answer this one and got it wrong the question is “find the measure of each angle indicates”
kondor19780726 [428]

Answer:

48

Step-by-step explanation:

Hi!

Remember, the sum of the angles on a straight angle is 180 degrees. Additionally, the sum of the measures of a triangle are 180 degrees.

Now, let's label the angles of the given triangle.

<DCE = y and <CDE=x

x+y+92=180

x+y= 88

Now, y+140 = 180 --> y= 40

x+40 = 88

x=48

The answer is 48 degrees.

Hope this is correct! Have a good day!

Check all the statements that are true:
Dahasolnce [82]

Answer:

The true statements are;

A, B, G, H, I, J

Step-by-step explanation:

To answer the question, we test each option as follows

A. If a and b both divide c, then ab divides c².

The above statement is true as c/a exists,

c/b exits therefore c²/ab = c/a×c/b

B. If p and q are distinct primes, then p2q2 has exactly 11 positive divisors.

The above statement is true as p² and q² each have 3 positive divisors, therefore, p²q² will also have pq and p²q² as possible divisors, therefore, true

C. If p and q are distinct primes, then p+q is prime as well.

The above statement is not correct as 5 + 7 = 12 an even number

D. If a divides b and c divides d, then a+c divides b+d.

The above statement is not correct as

8 is divisible by 2 and

9 is divisible by 3

but 17 is not divisible by 5

E. If p is prime, then so is p+2.

The above statement is not correct as 7 + 2 = 9 which is divisible by 3

G. If a and b both divide c, and a and b are relatively prime, then ab divides c.

The above statement is true as both a and b are factors of c

H. There are infinitely many prime numbers.

The above statement is true as there are infinitely many numbers

I. If p is prime, then p2 has exactly 3 positive divisors.

The above statement is true

1, p and p²

J. There are three consecutive odd numbers that are prime.

The above statement is true

3, 5, 7.
