Your goal is to create a college fund for your child. Suppose
you find a fund that offers an APR of 5% How much should
you deposit monthly to accumulate $170,000 in 15 years?
Answers
Answer:
the monthly payment is $636.02
Step-by-step explanation:
The computation of the monthly amount deposited i.e. PMT is given below:
GIven that
NPER = 15 × 12 months = 180
RATE = 5% ÷ 12 = 0.4167%
PV = $0
FV = $170,000
based on the above information
The formula is shown below:
= PMT(RATE;NPER;PV;FV;TYPE)
AFter applying the above formula, the monthly payment is $636.02
Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000.
The inequality 2764 + x Greater-than-or-equal-to 5000 can be used to determine the amount of money the family still needs to save. What is the solution to the inequality?
x Greater-than-or-equal-to 2236
x Greater-than-or-equal-to 7764
x Less-than-or-equal-to 2236
x Less-than-or-equal-to 7764?
Answers
Answer: x greater-than or equal-to 2,236
Step-by-step explanation:
5,000-2,764= 2,236

The national average for the number of students per teacher for all U.S. public schools is 15.9. A random sample of 12 school districts from a moderately populated area showed that the mean number of students per teacher was 19.2 with a variance of 4.41. Assume a normal distribution is appropriate for the number of students per teacher.a)[7 pts] Estimate the true mean number of students per teacher with 95% confidence from the random sample. b) [6 pts] A researcher makes the claim that moderately populated districts have a different number of students per teacher than the national average. Do the data support this claim
Answers
Answer:
The 95% confidence interval of the mean is
(17.8658, 20.5342)
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 15.9
Given that the size of the sample 'n' =12
Mean of the sample x⁻ = 19.2
Given that the variance of the sample = 4.41
The standard deviation of the sample (S) = 2.1
Step(ii):-
Degrees of freedom = n-1
ν = n-1 = 12-1=11
t₀.₀₅ = 2.2010
The 95% confidence interval is determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )[/tex]
[tex](19.2 - 2.2010 \frac{2.1}{\sqrt{12} } , 19.2 + 2.2010 \frac{2.1}{\sqrt{12} } )[/tex]
(19.2 - 1.3342 , 19.2+1.3342)
(17.8658 , 20.5342)
Final answer:-
The 95% confidence interval of mean is
(17.8658 , 20.5342)

Answers
Step-by-step explanation:
1. f(x) = 12x + 1
f(-2) = 12(-2) + 1 = -23
f(0) = 12(0) + 1 = 1
f(3) = 12(3) + 1 = 37
2. p(x) = -8x - 2
p(-2) = -8(-2) - 2 = 14
p(0) = -8(0) - 2 = -2
p(3) = -8(3) - 2 = -26
3. m(x) = -6.5x
m(-2) = -6.5(-2) = 13
m(0) = -6.5(0) = 0
m(3) = -6.5(3) = -19.5
4. s(x) = ⅖x + 3
s(-2) = ⅖(-2) + 3 = -⅘ + 3 = 11/5
s(0) = ⅖(0) + 3 = 3
s(3) = ⅖(3) + 3 = 6/5 + 3 = 21/5
5. h(x) = ¾x - 6
h(-2) = ¾(-2) - 6 = -6/4 - 6 = -30/4
h(0) = ¾(0) - 6 = -6
h(3) = ¾(3) - 6 = 9/4 - 6 = -15/4

Answer:

Step-by-step explanation:
We need to apply Mean Value theorem here.
We just need to calculate the average rate of change for each interval.
A) x=0 to x=4
We have the points (0,8) and (4,0) are the points that correspond to the endpoints of the given interval.
(8-0)/(0-4)
8/-4
-2
Not this choice
B) x=4 to x=8
We have the points (4,0) and (8,2) are the points that correspond to the endpoints of the given interval.
(2-0)/(8-4)
2/4
1/2
Not this choice
C) x=8 to x=12
We have the points (8,2) and (12,10) are the points that correspond to the endpoints of the given interval.
(10-2)/(12-8)
8/4
2
This one works.
D) x=12 to x=16
We have the points (12,10) and (16,1) are the points that correspond to the endpoints of the given interval.
(1-10)/(16-12)
-9/4
The table is an illustration of mean value theorem
[tex]\mathbf{f'(c) =2}[/tex] on the interval (8,12)
If a function is differentiable, then:
[tex]\mathbf{f'(c) =\frac{f(b) - f(a)}{b - a}}[/tex]
(a) (0,4)
This gives
[tex]\mathbf{f'(c) =\frac{f(4) - f(0)}{4 - 0}}[/tex]
[tex]\mathbf{f'(c) =\frac{f(4) - f(0)}{4}}[/tex]
From the table, we have:
[tex]\mathbf{f'(c) =\frac{0 - 8}{4}}[/tex]
[tex]\mathbf{f'(c) =\frac{- 8}{4}}[/tex]
[tex]\mathbf{f'(c) =-2}[/tex]
(b) (4,8)
This gives
[tex]\mathbf{f'(c) =\frac{f(8) - f(4)}{8 - 4}}[/tex]
[tex]\mathbf{f'(c) =\frac{f(8) - f(4)}{4}}[/tex]
From the table, we have:
[tex]\mathbf{f'(c) =\frac{2-0}{4}}[/tex]
[tex]\mathbf{f'(c) =\frac{2}{4}}[/tex]
[tex]\mathbf{f'(c) =\frac{1}{2}}[/tex]
(c) (8,12)
This gives
[tex]\mathbf{f'(c) =\frac{f(12) - f(8)}{12 - 8}}[/tex]
[tex]\mathbf{f'(c) =\frac{f(12) - f(8)}{4}}[/tex]
From the table, we have:
[tex]\mathbf{f'(c) =\frac{10-2}{4}}[/tex]
[tex]\mathbf{f'(c) =\frac{8}{4}}[/tex]
[tex]\mathbf{f'(c) =2}[/tex]
Hence, [tex]\mathbf{f'(c) =2}[/tex] on the interval (8,12)

Answer:

Step-by-step explanation:
Use the right triangle altitude theorem. The three triangles are right triangles and are similar.
MP/FP = FP/EP
MP/12 = 12/(EM + MP)
MP/12 = 12/(10 + MP)
MP(10 + MP) = 144
MP^2 + 10MP - 144 = 0
(MP + 18)(MP - 8) = 0
MP = -18 or MP = 8
Since a side length cannot be negative, the answer is MP = 8

The two triangles are similar, so their angles are the same, but their lengths are different.
If their angles are the same, then 98-6x=63-x.
98-6x=63-x (subtract: 98-63)
35-6x=-x (add 6x-x)
