Find the distance on maple street, in miles, from M to P
Answer:
8
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

Help please !!! ❗️❗️❗️❗️❗️❗️
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

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
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)

Solve : t+2t squared
Answer:
t=0 or t=-1/2
Step-by-step explanation:
Solve for t over the real numbers:
t (2 t + 1) = 0
Split into two equations:
t = 0 or 2 t + 1 = 0
Subtract 1 from both sides:
t = 0 or 2 t = -1
Divide both sides by 2:

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?
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

The table above gives selected values for the differentiable function f. in which of the following intervals must there be a number c such that f’(c)=2 PHOTO ATTACHED
Answer:
C.
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)

1: One shelf is 65cm long. Another shelf is 78cm long. What
is their total length in metres?
Answer:
1.43 Metres
Step-by-step explanation:
Since 1 Metre is equal to 100 centimetres, and 65 + 78 is 143 centimetres, to convert it to METRES we need to divide 143 by a hundred, making the output become 1.43 METRES.
The sum of the lengths of the shelves are 143 cm.
What are some alternative names for arithmetic operations?Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.
Given, One shelf is 65cm long. Another shelf is 78cm long.
Therefore, The sum of the lengths of the two trucks would be the sum of the individual lengths of the shelf which is,
= (65 + 78) cm.
= 143 cm.
