Answer:
The probability percentage that both players will be seniors is 15.38%.
Step-by-step explanation:
Given that a football team has 5 freshman, 8 sophomores, 11 juniors, and 16 seniors, if two are chosen at random to participate in the coin toss, to determine what is the probability that both players chosen will be seniors the following calculation must be done:
5 + 8 + 11 + 16 = 40
16/40 = X
4/10 = X
0.4 = X
15/39 = X
5/13 = X
0.38 = X
0.4 x 0.38 = X
0.1538 = X
Thus, the probability percentage that both players will be seniors is 15.38%.

(11x-28) + (10x-17) combine like terms
Answer:
21x-45
Step-by-step explanation:
(11x-28)+(10x-17)=11x-28+10x-17=21x-45
Hope this helps =]
Hey there!
(11x - 28) + (10x - 17)
= 11x - 28 + 10x - 17
COMBINE the LIKE TERMS
= (11x + 10x) + (-28 - 17)
= 11x + 10x - 28 - 17
= 21x - 45
Therefore, your answer is: 21x - 45

Two numbers are in the ratio 2:3 and have sum of 25...
What are the numbers?
Answer:
Use this as an example.
Step-by-step explanation:
a/b = 2/6 = 1/3
a/b = 1/3
b = 3a
a + b = a + 3a = 192
4a = 192
a = 192/4 = 48
b = 3a = 3(48) = 144

Answer:
You cant, because Ben is WRONG, unless you made a typo while writing the question
Step-by-step explanation:
If you subsitute N for 5, then the equation would be 7 x 5 = 45. However, this is not true. The correct equation is 7 x 5 = 35, so Ben is wrong UNLESS you made a typo while writing the question.

Monica bought a new house and she is looking to get cable and wifi. She is looking for reasonable prices. Monica is trying to compare two different companies. Comcast is charging $60 per month and $4 for any extra channels. On the other hand, Verizon is charging $45 per month and $6 for any extra channels.
=4+60
=6+45
PLEASE HELP ASAP
Answer:
I think she should get the Verizon house hold Wifi because when you compare the prices even if Monica doesn't want any extra channels she would still save $15. Even tho the extra channel was $4 for the Comcast when you add it up you get $64 instead when you use Verizon even tho you pay $6 for extra channels you still don't get the amount for the Comcast which you save $13 by getting Verizon with $51.

im an idiot sorry for waisting your time
The annual percentage rate is 6.5%.
Given that,
Sue bought a six-month CD for $5000. She said that at maturity it paid $162.50 in interest.Based on the above information, the calculation is as follows:
[tex]= (162.50 \times 2 \times 100\%) \div \$5,000[/tex]

6 Which equation has a solution of s = 9.5 ? F -5s = -47.5 G -3 + s = 12.5 H --2s 19 J –1 + s = 10.5
Answer:
F. -5s = -47.5
Step-by-step explanation:
F. -5s = -47.5
s = -47.5 / -5
s = 9.5
This is the correct option
G. -3 + s = 12.5
s = 12.5 + 3
s = 15.5 (Incorrect option)
J. –1 + s = 10.5
s = 10.5 + 1
s = 11.5 (Incorrect option)
Account (A) is a saving account , the interest earned after 1 year is $12 .If the interest rate is 3.2% for account (A). How much is the principle for account (A) ?3
Answer:
The principal for the account is $375.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
The interest earned after 1 year is $12 .If the interest rate is 3.2% for account (A).
This means, respectively, that [tex]t = 1, E = 12, I = 0.032[/tex]
We want to find P.
[tex]E = P*I*t[/tex]
[tex]12 = P*0.032*1[/tex]
[tex]P = \frac{12}{0.032}[/tex]
[tex]P = 375[/tex]
The principal for the account is $375.
The extract of a plant native to Taiwan has been tested as a possible treatment for Leukemia. One of the chemical compounds produced from the plant was analyzed for a particular collagen. The collagen amount was found to be normally distributed with a mean of 65 and standard deviation of 7.7 grams per mililiter. Round all answers to 4 decimal places.
Required:
a. What is the probability that the amount of collagen is greater than 60 grams per.
b. What is the probability that the amount of collagen is less than 90 grams per.
c. What percentage of compounds formed from the extract of this plant fall within 1 standard deviation of the mean?
Answer:
a) 0.2578 = 25.78% probability that the amount of collagen is greater than 60 grams per mililiter.
b) 0.9994 = 99.94% the probability that the amount of collagen is less than 90 grams per mililiter.
c) 68.26% of compounds formed from the extract of this plant fall within 1 standard deviation of the mean
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The collagen amount was found to be normally distributed with a mean of 65 and standard deviation of 7.7 grams per mililiter.
This means that [tex]\mu = 65, \sigma = 7.7[/tex]
a. What is the probability that the amount of collagen is greater than 60 grams per.
This is 1 subtracted by the pvalue of Z when X = 60. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 65}{7.7}[/tex]
[tex]Z = -0.65[/tex]
[tex]Z = -0.65[/tex] has a pvalue of 0.2578
0.2578 = 25.78% probability that the amount of collagen is greater than 60 grams per mililiter.
b. What is the probability that the amount of collagen is less than 90 grams per.
This is the pvalue of Z when X = 90.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{90 - 65}{7.7}[/tex]
[tex]Z = 3.25[/tex]
[tex]Z = 3.25[/tex] has a pvalue of 0.9994
0.9994 = 99.94% the probability that the amount of collagen is less than 90 grams per mililiter.
c. What percentage of compounds formed from the extract of this plant fall within 1 standard deviation of the mean?
Between Z = 1 and Z = -1, so the proportion is the pvalue of Z = 1 subtracted by the pvalue of Z = -1
Z = 1 has a pvalue of 0.8413
Z = -1 has a pvalue of 0.1587
0.8413 - 0.1587 = 0.6826
0.6826*100% = 68.26% of compounds formed from the extract of this plant fall within 1 standard deviation of the mean
Trever invested $10,000 in an account that earns 8.5%
interest that is compounded monthly.
(a) Write an exponential model for the balance of the
account.
(b) Determine the amount of money in the account
after 15 years.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Trever invested $10,000 in an account that earns 8.5% interest that is compounded monthly.
First, we need to calculate the monthly interest rate:
i= 0.085 / 12= 0.00708
Now, to calculate the future value of the investment, we need to use the following formula:
FV= PV*(1+i)^n
PV= initial investment
i= interest rate
n= number of periods
In this case:
FV= 10,000*(1.00708^n)
Finally, for 15 years:
n= 15*12= 180 months
FV= 10,000*(1.00708^180)
FV= $35,605.31
