What percent is 29 dollars out of 122.50 and what percent of 122.50 is it?

29/122.50*100% = 23.67%

What percent is 28.50 dollars out of 122.50 and what percent of 122.50 is it?

28.50/122.50*100% = 23.27%

What percent is 33 dollars out of 122.50 and what percent of 122.50 is it?

33/122.50*100% = 26.94%

What percent is 32 dollars out of 122.50 and what percent of 122.50 is it?

32/122.50*100% = 26.12%

Note: all results are rounded to the nearest hundredths

Answer:

19 days

Step-by-step explanation:

1 - Make an equation with the variables provided.

150 + 200 + 12.50x = 587.50

2 - Simplify both sides.

350 + 12.50x = 587.50

3 - Subtract 350 from both sides.

12.50x = 237.50

4 - Divide by 12.50 to find your x variable.

x = 19 days

QveST [7]

Answer:

y= 7

Step-by-step explanation:

Plug in values into y=mx+b

m= slope

b= y intercept

Since slope is 0, y will always be at 7.

y= 0(x) +7

y= 7

The probability that an electronic device produced by a company does not function properly is equal to 0.1. If 10 devices are bo

Answer:

Correct option: A. P=0.057

Step-by-step explanation:

Binomial Distribution

The binomial distribution fits the case of n independent events each one with a probability of success equal to p where k successes have been achieved.

The PMF (Probability Mass Function) of the binomial distribution is

$\displaystyle P(k,n,p)=\binom{n}{k}p^kq^{n-k}$

Where $q = 1-p$

The individual probability that an electronic device does not function properly is p=0.1. We know n=10 devices have been bought and we want to compute the probability that 7 devices function properly. Please notice that this is not the value of k since p is the probability of failure. The correct value of k=10-7=3. The required probability is

$\displaystyle P(3,10,0.1)=\binom{10}{3}0.1^30.9^{10-3}$
