You are given a bag of jelly beans. There are 7 red, 8 blue, 4 yellow, and 10 pink. Find the probability of drawing 2 blue in a

miss Akunina [59]

Okay so the probability of drawing a blue bean is

8 / 29 = .276

29 is the total number of jelly beans

When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.

But to find the probability of drawing a blue two times in a row, we must square the probability .

(.276) • (.276) = 0.076

Your answer is 7.6% !

If your have any questions, leave a comment! I hope I helped :)

Mr. Parker's class has 7 feet of white paper and 8 feet of yellow paper to make posters they will cut the paper into 2-foot post

Viktor [21]

Answer:

In total, they will be able to cut 7 posters.

Step-by-step explanation:

Mr. Parker's class has 7 feet of white paper and 8 feet of yellow paper to make posters.

If they cut the paper into 2-foot posters, then from 8 feet of yellow paper they will make $\frac{8}{2} = 4$ posters.

Now, from the 7 feet white paper if they cut 2-foot posters then they will make 3 posters maximum as $\frac{7}{2} = 3.5$ .

Therefore, in total, they will be able to cut (4 + 3) = 7 posters. (Answer)

What is the estimate of forgive 6in by 4in

NNADVOKAT [17]

Find area of the semi circle.

The diameter is, half of that would be the radius, which is 3.

$\frac{\pi \cdot 3^2}{2}$ = 14.1

Find the area of the rectangle.

6 * 4 =24

Add the two areas together.

24 + 14.1 = 38.1

$38.1in^2$

A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and

RUDIKE [14]

Answer:

193 mg

Step-by-step explanation:

Exponential decay formula:

$A_t = A_0e^r^t$
where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = time

Our known variables are:

1998 to the year 2004 is a total of t = 6 years.
The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.

Let's solve for the decay constant of this sample.
