Hei has $1,300 in a retirement account earning 4% interest compounded annually. Each year after the first, she makes additional deposits of $1,300. After 5 years, what was her account balance if she did not make any withdrawals? Round each year's interest to the nearest cent if necessary.
The account had a balance of $
after 5 years.
Answers
Answer:
Her account balance after 5 years is $8702.87
Step-by-step explanation:
1500 (1.05) = 1575 --> after one year
1575 + 1500 = 3075
3075 (1.05) = 3228.75 --> after two years
3228.75 + 1500 = 4728.75
4728.75 (1.05) = 4965.1875 --> after three years
4965.1875 + 1500 = 6465.1875
6465.1875 (1.05) = 6788.44688 --> after four years
6788.44688 + 1500 = 8288.44688
8288.44688 (1.05) = 8702.86922 --> after five years = $8702.87

A high school administration is considering making the school day shorter by reducing time between class periods. They conducted a
survey of 25 randomly selected students to get student feedback. From the survey, 20 of the 25 students would prefer the shorter
school day, even if it means less time between classes.
The school administration then administered the survey to five more groups of 25 randomly selected students. The study yielded
similar results in each of the groups. What generalization can be made from the results of this study?
About 80% of the students would prefer the shorter school day
The results are inconclusive; therefore a generalization cannot Je made regarding which option is selected more often.

Step-by-step explanation:
Nielsen Rating: The television show nbc Sunday night football broadcast a game between the colts and patriots and received a share of 22, meaning that among the tv sets in use, 22% are turned to that game (based on data from Nielsen Media Research). An advertiser wants to obtain a second opinion by conducting its own surveys and a pilot survey begins with 20 households having tv sets in use at the time of that same nbc Sunday night football broadcast.
a. Find the probability that none of the households are turned to nbc Sunday night football (3 digits)
b. Find the probability that at least one of the households is turned to nbc Sunday night football.(3 digits)
c. Find the probability that at most one of the households is turned to nbc Sunday night football (3 digits)
d. If at most one household is turned to nbc Sunday night football, does it appear that the 22% share value is wrong? Why or why not?
Answers
Answer:
a. 0.007 = 0.7% probability that none of the households are turned to nbc Sunday night football
b. 0.993 = 99.3% probability that at least one of the households is turned to nbc Sunday night football.
c. 0.046 = 4.6% probability that at most one of the households is turned to nbc Sunday night football
d. 1 is less than 2.5 standard deviations below the mean, so having at most one people watching shouldn't be considered an unusual outcome, which means that the 22% share values does not appear wrong.
Step-by-step explanation:
For each household, there are only two possible outcomes. Either it is tuned to Sunday Night Football, or it is not. The probability of a household being tuned to Sunday Night Football is independent of any other household. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
22% are turned to that game
This means that [tex]p = 0.22[/tex]
Sample of 20 households:
This means that [tex]n = 20[/tex]
a. Find the probability that none of the households are turned to nbc Sunday night football:
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.22)^{0}.(0.78)^{20} = 0.007[/tex]
0.007 = 0.7% probability that none of the households are turned to nbc Sunday night football.
b. Find the probability that at least one of the households is turned to nbc Sunday night football.
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
Since P(X = 0) = 0.007
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.007 = 0.993[/tex]
0.993 = 99.3% probability that at least one of the households is turned to nbc Sunday night football.
c. Find the probability that at most one of the households is turned to nbc Sunday night football (3 digits)
This is
[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.22)^{0}.(0.78)^{20} = 0.007[/tex]
[tex]P(X = 1) = C_{20,1}.(0.22)^{1}.(0.78)^{19} = 0.039[/tex]
[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.007 + 0.039 = 0.046[/tex]
0.046 = 4.6% probability that at most one of the households is turned to nbc Sunday night football.
d. If at most one household is turned to nbc Sunday night football, does it appear that the 22% share value is wrong? Why or why not?
A measure is considered unusually low if it is more than two and a half standard deviations below the mean.
The mean is:
[tex]E(X) = np = 20*0.22 = 4.4[/tex]
The standard deviation is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{20*0.22*0.78} = 1.8526[/tex]
4.4 - 2.5*1.8526 = -0.2.
1 is less than 2.5 standard deviations below the mean, so having at most one people watching shouldn't be considered an unusual outcome, which means that the 22% share values does not appear wrong.
If the sum of a number and one is doubled, the result is four less than the number. Find the number
Answers
Answer:
-6
Step-by-step explanation:
Let the number be 'x'
Sum of a number and one = x + 1
Sum of a number and one is doubled = 2*(x +1) = 2*x + 2*1 = 2x + 2
Four less than the number = x - 4
2x + 2 = x - 4
Subtract 'x' from both sides
2x - x + 2 = x - x - 4
x + 2 = -4
No, subtract 2 form both sides
x + 2 -2 = - 4 - 2
x = -6

The area for the sector of a circle is
[tex]A_s=\frac{theta}{360}*\pi r^2[/tex] where theta is the measure of the central angle. We have some given values to fill in:
Area is 64π and the central angle is 90°, so all we have left to find is the radius. Filling into the equation:
[tex]64\pi =\frac{90}{360}*\pi r^2[/tex]
Let's get that solved for r-squared first:
[tex]\frac{360(64\pi )}{90\pi } =r^2[/tex]
Doing all the math on that gives us:
[tex]256=r^2[/tex]
Take the square root of both sides and get that r = ±16. BUT we know that lengths cannot be negative, so we disregard the -16 and say that the radius is 16 inches.

Choose the option that best answers the question. Paracelsus University has two kinds of professors: academic professors and professional professors. At Paracelsus University, 60% of the professors are academic professors, and 70% of the professors are tenured. If 90% of the professors at Paracelsus University are academic professors or tenured or both, then what percent of the professional professors there are tenured
Answers
Answer:
75%
Step-by-step explanation:
The computation of the percent of the professional professors there are tenured is shown below;
Given that
academic professors A = 60%
professors tenured P = 70%
professors at Paracelsus University = 90%
Based on the above information
As we know that 90% of the professors could be academic professors or tenured or both
so here we can say that the percent of academic professors is
= 60 + 70 - 90
= 40
Therefore professors tenured will be
= 70 - 40
= 30
Now the percentage of professional professor that is tenured is
= 30 ÷ 40 × 100
= 75%

Write an equation for a line perpendicular to y = 2 x + 4 and passing through the point ( − 2 , 3 ) . Express your answer in slope-intercept form.
Answers
Answer:
y = -1/2x + 2
Step-by-step explanation:
A perpendicular line will have a opposite reciprocal slope.
Since the line's slope is 2, the perpendicular line will have a slope of -1/2
Plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
3 = -1/2(-2) + b
3 = 1 + b
2 = b
Plug in the slope and b into y = mx + b
y = -1/2x + 2
So, the equation is y = -1/2x + 2
5 + (1/7)b = -2 find what b equals
Answers
Answer:
