Suppose you want to save in order to purchase a new boat. Take the APR to be 6.0%.
You want to have $15,000 toward the purchase of a boat in three years. How much do you need to deposit each month? (Round your answer to the nearest cent.)
Answer:
Amount deposit each month = $365.26
Step-by-step explanation:
Given:
Amount deposit = $15,000
Rate = 6% = 6% / 12 = 0.005
Number of time = 3 x 12 = 36
Find:
Amount deposit each month
Computation:
Amount deposit each month = [(15,000) x 0.005]/[(1.005){(1.005)³⁶-1}]
Amount deposit each month = $365.26
The amount needed to be deposited each month is;
P ≈ $393.23
We are given;
APR = 6% = 0.06
Total accumulated amount; A = $15000
number of years; n = 3 years
To calculate the amount needed to be deposited each month, we will use the formula;
A = [P(1 + APR/12)¹²ⁿ - 1)] ÷ (APR/12)
Plugging in the relevant values gives;
15000 = [P(1 + (0.06/12))⁽¹²*³⁾ - 1] ÷ (0.06/12)
Rearrange to get;
[P(1 + (0.06/12))³⁶ - 1] = 15000 × 0.06/12
⇒ [P(1 + 0.005)³⁶ - 1] = 75
⇒ P(0.19073) = 75
⇒ P = 75/0.19073
⇒ P ≈ $393.23

-5(2× - 4)=2(x - 8) with work please :)
Answer:
Step-by-step explanation:
−5(2)(−4)=2(x−8)
Simplify both sides of the equation.
−5(2)(−4)=2(x−8)
−5(2)(−4)=(2)(x)+(2)(−8)(Distribute)
40=2x+−16
40=2x−16
Step 2: Flip the equation.
2x−16=40
Step 3: Add 16 to both sides.
2x−16+16=40+16
2x=56
Step 4: Divide both sides by 2.
2x/2 = 56/2
x=28

A polling agency is investigating the voter support for a ballot measure in an upcoming city election. The agency will select a random sample of 400 voters from one region, Region A, of the city. Assume that the population proportion of voters who would support the ballot measure in Region A is 0.46.
Required:
What is the probability that the proportion of voters in the sample of Region A who support the ballot measure is greater than 0.50?
Answer:
0.0544
Step-by-step explanation:
From the given information;
The population proportion of the voters that would support the ballot measures in region A = 0.46
The random sample n = 400 voters
The required probability can therefore be computed as follows:
[tex]P[p_1>0.5] = P \bigg [ \dfrac{p_1-P_1}{\sqrt{\dfrac{P_1(1-P_1)}{n_1}}}>\dfrac{0.5-0.46}{\sqrt{\dfrac{0.46(1-0.46)}{400}}} \bigg][/tex]
[tex]P[p_1>0.5] = P \bigg [ Z>\dfrac{0.04}{\sqrt{\dfrac{0.46(0.54)}{400}}} \bigg][/tex]
[tex]P[p_1>0.5] = P \bigg [ Z>\dfrac{0.04}{\sqrt{6.21\times 10^{-4}}} \bigg][/tex]
[tex]P[p_1>0.5] = P \bigg [ Z>1.605 \bigg][/tex]
[tex]P[p_1>0.5] = 1- P [ Z<1.605 ][/tex]
Using the Excel Function =NORMDIST(1.605)
[tex]P[p_1>0.5] = 1- 0.9456[/tex]
[tex]P[p_1>0.5] =0.0544[/tex]
Therefore, the required probability = 0.0544

Pregnancy length (in days) is a normally distributed random variable with a mean of 266 days and a standard deviation of 16 days. Calculate the z-score for a pregnancy lasting 286 days. Do not round.
Answer:
it=552
Step-by-step explanation:
with rounding it = 550
The value of z-score for a pregnancy lasting 286 days will be;
⇒ z - score = 1.25
What is Standard deviation?Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given that;
Mean = 266 days
Standard deviation = 16 days
Now,
We know that;
⇒ z - score = (X - μ) / σ
Substitute all the values, we get
⇒ z - score = (286 - 266) / 16
⇒ z - score = 20/16
⇒ z - score = 1.25
Thus, The value of z - score = 1.25

the first term of GP where second term is 2 and sum of infinity is8 it will be
Answer:
a = 4
Step-by-step explanation: Given that
ar=2 where a is the first term and is the common ratio.
ar=2 ............1
Also give that a/1-r = 8 where a is the first term and r is the common ratio as well.
a/1-r = 8 ......... 2
From equation 1 make r the subject
ar=2
r= 2/a...........3
Put equation 3 into 2
a/1-2/a =8
a÷1-2/a
a = 8(1-2/a)
a= 8/1-16/a
a/1= 8a-16
a^2= 8a-16
Rewriting the above equation
a^2-8a+16=0
This will eventually be
a^2-8a+16=0
(a-4)^2= 0
a =4

A company that makes hair-care products had 7,000 people try a new shampoo. Of the 7,000 people, 56 had a
mild allergic reaction. What percent of the people had a mild allergic reaction?
Answer:
0.8
Step-by-step explanation:
i believe it would be 56/7000 and you multiply your answer 0.008 by 100 so 0.8 had a mild reaction
Answer:
0.8%
Step-by-step explanation:
Think of it as a fraction: 56/7,000. To get a percent you want to simplify the denominator to 100. Then what you do to the denominator, you must do to the numerator, so simplify 56 by the number you simplified 7,000 to get to 100. Then you will have your answer of 0.8%.
Last year Mr Peterson had a fence all the way around his garden. He can reuse all of the fence he had around the garden last year but he needs to buy more fencing to go around this years garden. How many more meters of fencing is needed for this years garden than last years?
Complete Question:
Last year Mr. Petersen’s rectangular garden had a width of 5 meters and an area of 20 square meters. This year he wants to make the garden three times as long and two times as wide.
Last year, Mr. Petersen had a fence all the way around his garden. He can reuse all of the fence he had around the garden last year, but he needs to buy more fencing to go around this year’s garden.
How many more meters of fencing is needed for this year’s garden than last year’s?
Answer:
26 meters of fencing needed
Step-by-step explanation:
Given
Last Year:
[tex]Width = 5m[/tex]
[tex]Area = 20m^2[/tex]
This Year:
[tex]Length = 3\ times\ longer[/tex]
[tex]Width = 2\ times\ wider[/tex]
Required
Determine how many more meters is needed
Represent last year's length of Fence with L and last year's width with W
First, we need to calculate L
[tex]Area = L * W[/tex]
Where
[tex]Area = 20m^2[/tex]
[tex]W = 5m[/tex]
[tex]20m^2 = L * 5m[/tex]
Divide both sides by 5m
[tex]\frac{20m^2}{5m} = \frac{L * 5m}{5m}[/tex]
[tex]\frac{20m^2}{5m} = L[/tex]
[tex]L = \frac{20m^2}{5m}[/tex]
[tex]L = 4m[/tex]
So, we have that:
For Last Year
[tex]Length = 4m[/tex] and [tex]Width = 5m[/tex]
For this year:
[tex]Length = 3\ times\ longer[/tex]
[tex]Length = 3 * 4m[/tex]
[tex]Length = 12m[/tex]
[tex]Width = 2\ times\ wider[/tex]
[tex]Width = 2 * 5m[/tex]
[tex]Width = 10m[/tex]
So, for this year, we have:
[tex]Length = 12m[/tex] and [tex]Width = 10m[/tex]
Next, we calculate perimeter of fencing in both years.
[tex]Perimeter = 2 * (Length + Width)[/tex]
Last Year:
[tex]Perimeter = 2 * (4m + 5m)[/tex]
[tex]Perimeter = 2 * 9m[/tex]
[tex]Perimeter = 18m[/tex]
This Year:
[tex]Perimeter = 2 * (12m + 10m)[/tex]
[tex]Perimeter = 2 * 22m[/tex]
[tex]Perimeter = 44m[/tex]
To get the meters of fencing needed this year, we simply calculate the difference in the calculated perimeters.
[tex]Difference = 44m - 18m[/tex]
[tex]Difference = 26m[/tex]
Hence, there are 26 meters of fencing needed

Find the equation of the line.
The line is perpendicular to y = 1/2x +5 and passes through the point (4,7).
The equation of the line is: y =
Answer:
y=-2x+15
Step-by-step explanation
A perpendicular line always has the opposite reciprocal slope of the line it is 90 degrees from.
Since the slope of the other line is 1/2, the slope of this line must be -2. And with the slope of a line -2 with point (4,7), you can start plugging in numbers.
y=-2x+b
7= -2(4)+b
7= -8+b
15=b
Therefore, the equation of the line is y=-2x+15

Refrigerators in a random sample of 55 refrigerators, the mean repair cost was $150.00 and the standard deviation was $15.50. Construct a 90% confidence interval for the population mean repair cost. Interpret the results.
Answer:
146.5619<x<153.4381
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as:
CI = xbar±(z*s/√n)
xbar is the mean = 150
s is the standard deviation = 15.50
n is the sample size = 55
z is the z score at 90% CI = 1.645
Substitute and get CI
CI = 150±(1.645*15.50/√55)
CI = 150±(1.645*15.50/7.4162)
CI = 150±(1.645*2.09)
CI = 150±(3.4381)
CI = (150-3.4381, 150+3.4381)
CI = (146.5619, 153.4381)
CI = 146.5619<x<153.4381
Hence a 90% confidence interval for the population mean repair cost 146.5619<x<153.4381
The minimum cost is approximately $147 while the maximum cost of the refrigerator is $153

Slope intercept form is y=mx+b
m is the slope, and b is the y intercept
FIrst we have to find the slope which is rise/run
Since our points are (-2,0) and (0,5) the equation will be:
5-0/0-(-2)
5/2
The slope is 5/2
