A bowl contains 28 black, 21 red, 23 blue, and 10 green balls

Licemer1 [7]

Answer:

P (blue) = 23 / 82

Step-by-step explanation:

There are 23 blue out of 82 (28 + 21 + 23 + 10 = 82) balls

or,

23 / 82

So, the probability of a blue ball being chosen is 23/82

(or a 28% chance [rounded])

7100 dollars is placed in an account with an annual interest rate of 5%. To the nearest tenth of a year, how long will it take f

kow [346]

Answer:

After $26.91\ years$ the principle amount value will reach to $26400\ dollars$ .

Step-by-step explanation:

Given that,

Principle Amount $(P)= 7100\ dollars$

Rate of Interest $(R)=$ $5$ %

Total Amount $(A)= 26400\ dollars$

If Principle Amount $(P)$ $=P\ dollars$ , Time $=t\ years$ , Rate of Interest $=R$ % $pa$

when interest is compounded annually:

Total Amount after $t\ years$ $= P(1+\frac{R}{100}) ^{t}$

Now,

$A= P(1+\frac{R}{100}) ^{t}$

⇒ $26400=7100(1+\frac{5}{100}) ^{t}$

⇒ $3.7183=(1+0.05)^{t}$

⇒ $3.7183=(1.05)^{t}$

taking log both sides, we get

$ln(3.7183)=ln {(1.05)^{t}}$

⇒ $1.31327=t\times ln(1.05)$

⇒ $1.31327=t\times 0.04879$

⇒ $t=26.91$

Therefore,

After $26.91\ years$ the principle amount value will reach to $26400\ dollars$ .

Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$

If Ruby plans on making 4 batches of pancakes, how many combined cups of powdered milk and whole wheat flour does she need?

Trava [24]

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

Given the <em>quantities</em> of powdered milk and whole wheat to prepare a batch of pancakes, we can determined the <em>total</em> amount of each ingredient by simple rule of three:

Powdered milk

$x = 4\,batches\times \frac{1}{4}\,\frac{cups}{batch}$

$x = 1\,cup$

Whole wheat

$y = 4\,batches \times \frac{3}{2}\,\frac{cup}{batch}$

$y = 6\,cups$

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.
