Amy plans to spend 1/4 of his next month's income on
rent, 1/12 on transportation, 1/6 on food, $590 on other
expenses, and save $925. How much does he plan to
spend on food?
Answers
9514 1404 393
Answer:
$505
Step-by-step explanation:
Assuming the listed expenses comprise all of Amy's income (x), we have ...
(1/4)x +(1/12)x +(1/6)x + 590 +925 = x
1515 = 1/2x . . . . . . subtract 1/2x
We note that 1/6x is for food. That amount is 1/3 of 1/2x, so the amount spent on food is ...
(1/6)x = (1/3)(1/2x) = (1/3)(1515) = 505
Amy plans to spend $505 on food.

the answer is $505

4 10.40 108.16 10.70 114.49
5 10.20 104.04 10.40 108.16
∑ 51.5 530.49 52.3 547.51
x`= ∑x/n1 = 51.5/5= 10.3; y`= ∑y/n2= 52.3/5= 10.46
Sx² = 1/n1-1[ ∑x² - (∑x)²/n1] = 1/4[ 530.49 - (51.5)²/5]
= 1/4[ 530.49 - 530.45] = 0.01
Sy² = 1/n2-1[ ∑y² - (∑y)²/n2] = 1/4[ 547.51 - (52.3)²/5]
= 1/4[ 547.51 - 547.058] = 0.113
F= Sx²/Sy²= 0.01/0.113= 0.08849
The critical region is F ≥ F(0.025) (5,5)= 7.15
and F ≤ 1/F(0.025) (5,5) = 1/7.15= 0.13986
Since the calculated value of F =0.08849 falls in the critical region we conclude that the two standard deviations for the locations significantly different at the 95% confidence level.
c. t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)
t= 10.3-10.46/ sqrt( 0.01/5 +0.113/5)
t=- 0.16/0.15684
t= -1.020
d. The calculated value t= -1.020 does not fall in the the critical region
t (0.025) (4) = ±2.776 we conclude that the means for the two different locations are not significantly different at the 95% confidence level.

Answers
Answer:
h = 65, g = 115, m = 49, k = 131
Step-by-step explanation:
h and 115 are supplementary angles, so 180 - 115 is 65 degrees.
g and 115 are vertical angles, so both should be 115 degrees.
m and 131 are supplementary angles, so 180 - 131 = 49 degrees.
k and 131 are vertical angles, so both should be 131 degrees.
The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectangle is (p + 5) inches, what is the width?
Answers
Answer:
[tex]Width = p + 4[/tex]
Step-by-step explanation:
Given
[tex]Area = p^2 + 9p + 20[/tex]
[tex]Length = p + 5[/tex]
Required
Determine the width
The area of a rectangle is:
[tex]Area = Length * Width[/tex]
This gives:
[tex]p^2 + 9p + 20= (p+5)* Width[/tex]
Expand
[tex]p^2 + 4p + 5p + 20= (p+5)* Width[/tex]
Factorize
[tex]p(p + 4) + 5(p + 4)= (p+5)* Width[/tex]
[tex](p + 5) (p + 4)= (p+5)* Width[/tex]
Divide both sides by p + 5
[tex]p + 4= Width[/tex]
[tex]Width = p + 4[/tex]

3x+3+3x+3+5x+7+4x-1+4x-1=106
19x+11=106
19x=95
x=5
JL=5(5)+7=32
ST=1/2 of JL = 1/2 of 32 = 16
The length of midsegment ST will be 6. The perimeter of the triangle is given.
What is perimeter?It's the sum of length of the sides used to make the given figure.
The perimeter of AJKL is 106;
⇒KS+SJ+JL+LT+TK=106
⇒3x+3+3x+3+5x+7+4x-1+4x-1=106
⇒19x+11=106
⇒19x=95
⇒x=5
The side JL is obtained by,x=5
JL=5x+7
JL=5×(5)+7
JL=32
The side ST is obtained
ST=(1/2)×JL
ST= 1/2 of 32
ST = 16
Hence, the length of midsegment ST will be 16.

The number of wrongly dialed phone calls you receive can be modeled as a Poisson process with the rate of one per month. For simplicity, assume there are four weeks in one month.
a. Find the probability that it will take between two and three weeks to get the first wrongly dialed phone call.
b. Suppose that you have not received a wrongly dialed phone call for two weeks. Find the expected value and variance of the additional time until the next wrongly dialed phone call.
Answers
Answer:
Part a: P (14/30<x<21/30) = 0.1304
Partb: Expected value= Variance= 0.866
Step-by-step explanation:
The poisson distribution is given by
P(x)= μˣ . e^ -u/ x!
In this question
x= 1
n= 30
μ= 1/30
P(x)= μˣ . e^ -u/ x!
= 0.333. e⁻¹/³⁰/1!
= 0.33*0.967/1
= 0.32208
For 2 weeks
x= 14
n= 30
μ= 14/30
P(x)= μˣ . e^ -u/ x!
= 0.467. e⁻¹⁴/³⁰/14!
= 0.467*0.627/14!
= 0.29285/14!
=3.359*e⁻¹²
= 0.0139
For 3 weeks
x= 21
n= 30
μ= 21/30
P(x)= μˣ . e^ -u/ x!
= 0.7* e⁻²¹/³⁰/21!
= 0.7*0.4965/21!
= 0.3476/21!
=6.8037*e⁻²¹
= 0.11648
Part a:
P (14/30<x<21/30) = P (x= 14/30) + P (x=21/30)
(0.0139 +0.11648) =0.1304
Part b:
Probability of Not receiving the call for two weeks = 1- P (x= 14/30)=0.9861
The mean and the variance of the Poisson distribution are equal to μ
For x= 14
Expected value not getting wrongly dialed phone call in 2 week = μ= 1-14/30 = 1-0.467= 0.533
Variance of not getting wrongly dialed phone call in 2 week= μ=1- 14/30= 1-0.467= 0.533
Expected value of the additional time until the next wrongly dialed phone call
Expected value not getting wrongly dialed phone call in 2 weeks + Expected value of next wrongly dialed phone call in a month
= 0.533+0.33=0.866
Variance of the additional time until the next wrongly dialed phone call
= Expected value of the additional time until the next wrongly dialed phone call =0.866
