Answer:
a = 1500
b = 0.97
Step-by-step explanation:
Let's define 2014 as our t = 0.
Then t = 1 will be 2015, and so on.
We know that in 2014 the population was 1500.
It decreases at an annual rate of 3% or 0.03 in decimal form.
Then in 2015, the population was: 1500 - 1500*0.03 = 1500*(0.97)
In 2016, the population was: 1500*(0.97) - 1500*(0.97)*0.03 = 1500*(0.97)^2
We already can see the pattern.
t years after 2014, the population will be:
f(t) = 1500*(0.97)^t
Now, answering the question:
using f(t)=a(b)^t what is the value of a and b?
a = 1500
b = 0.97

Joe Summers buys a gas grill and accessories. The cost, including tax, amounts to $850.00. Joe finances the grill over 12 months after making a $150 down payment. The true annual Interest rate is 14%. What are Joe's monthly payments (principal plus Interest)?
To the nearest penny, c = $ Total of payments = amount financed + c = $ Total of payments = number of payments = monthly payment = $
Answer:
"$66.5
Step-by-step explanation:
The cost, including tax, amounts to $850.00.
Down payment =$150
Amount after paying down payment = $850-$150=$700
Interest rate = 14 %
So, interest on $700 =
So, c = $98
Total payment = amount financed + c = 700+98=$798
Now Joe finances the grill over 12 months
So, no. of payments = 12
Now Monthly payment = Total of payments ÷ number of payments
=798 ÷ 12
=$66.5
Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!

the largest orange in a bag has the circumference of 9 5/8 inches. The smallest orange has a circumference
of 7 13/16 inches. Write the difference of the circumferences of the smallest orange and the largest orange
Answer:
1.81 inches
Step-by-step explanation:
Given that,
The circumference of the largest orange in a bag is [tex]9\dfrac{5}{8}\ \text{inches}[/tex] and that of smallest orange is [tex]7\dfrac{13}{16}\ \text{inches}[/tex].
Difference = largest orange - smallest orange
= [tex]9\dfrac{5}{8}-7\dfrac{13}{16}\\\\=\dfrac{77}{8}-\dfrac{125}{16}\\\\=\dfrac{29}{16}\\\\=1.81\ \text{inches}[/tex]
So, difference of the circumferences of the smallest orange and the largest orange is 1.81 inches
An EWMA control chart uses λ = 0.5. What is the value of L such that the control limits of this EWMA control chart in the steady state have the same width with a 3σ X_bar control chart?
Answer:
5.199
Step-by-step explanation:
From the information provided;
We know that λ = 0.5.
However, the control limits for a steady-state EMWA control chart is:
[tex]\mu_o \pm L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
where;
[tex]UCL = \mu_o + L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
[tex]LCL = \mu_o- L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
Given that the data is chosen from an individual sample;
Then; we can express the width as:
[tex]L \sigma \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3 \sigma[/tex]
[tex]L \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(2-0.5)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(1.5)}}= 3[/tex]
[tex]L \sqrt{0.333}= 3[/tex]
[tex]L\times 0.577= 3[/tex]
[tex]L=\dfrac{ 3 }{0.577}[/tex]
L = 5.199

bob needs to mix 2 cups of orange juice concentrate with 3.5 cups of water to make orange juice. bob has 6 cups of concentrate. how much orange juice can he make? please explain
Answer:
10.5
Step-by-step explanation:
First, divide 6 by 2. You get 3, right? So now you know that you multiply by three to get the answer. 3.5 * 3 will equal 10.5
If 2 cups of orange juice concentrate and 3.5 cups of water are needed to make a glass of orange juice, then 6 cups of orange juice concentrate will make 3 cups. This is because 6/2 is 3.
However, this answer is only correct if you also have the necessary amount of water. (2 x 3 is 6, so you will need to multiply 3.5 x 3 to determine how much water you'll need: 3.5 x 3 = 10.5).
Thus, given that you have the necessary amount of water, you will be able to make 3 cups of orange juice with 6 cups of concentrate.
Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below.
Original claim: Less than 51% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0148
a. State a conclusion about the null hypothesis. (Reject Upper H0 or fail to reject Upper H0
Choose the correct answer below.
A.Reject Upper H0 because the P-value is less than or equal to to α.
B. Reject Upper H0 because the P-value is greater than α.
C. Fail to reject Upper H0 because the P-value is greater than α.
D. Fail to reject Upper H0 because the P-value is less than or equal to α.
b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?
A. The percentage of adults that would erase all of their personal information online if they could is less than or equal to 51%.
B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
C. The percentage of adults that would erase all of their personal information online if they could is more than 51%.
D. There is not sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
Answer:
A.Reject Upper H0 because the P-value is less than or equal to to α.
B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
Step-by-step explanation:
Given the claim :
Less than 51% will erase their personal information :
We take this as the null ;
H0 < 0.51 ;
Alternative hypothesis which is the opposite of the Null
H1 > 0.51
P value = 0.0148
α = 0.05
At α = 0.05 ; if p value is less than α ; reject the the Null
If p value is greater than Null ; then we fail to reject the Null
Pvalue < α
The P value is less than 0.05; then we reject the Null
B.) There is significance evidence to support the Alternative hypothesis claim, that the percentage of adult that would erase all their personal information online if they could is more Than 51%
