Answer:
b. 710
Fail to reject H0
Step-by-step explanation:
Forecast for July 14 :
Assume there are 4 wwwks in each month :
January to June = ( 4 * 6 months) = 24 weeks in 6 months ;
July - July 14 = 2 weeks :
2 + 24 = 26 weeks
The model given :
Y = 450 + 10t
Y = 450 + 10(26)
Y = 450 + 260
Y = 710
2.)
Test is a 2 tail test :
Zstatistic = - 1.07
At 95% confidence = ±1.96
Zcritical = - 1.96
Hence,
Reject H0 if ;
Zstatistic < Zcritical
-1.07 > 1.96
Hence, fail to reject H0.

Answer:
square, parallelogram, rectangle, rhombus
Step-by-step explanation:
Considering the answer choices:
Square
Regular pentagon
Parallelogram
Rectangle
Rhombus
It can't be a pentagon because it only has four sides.
Properties of the shapes:
Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.
Rhombus - quadrilateral with four congruent sides.
Square - quadrilaterals with all properties of rectangles and rhombi.
Parallelogram - rectangles, rhombi, and squares are parallelograms.
This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.

How much did they pay
Answer:
The answer is B
Step-by-step explanation:
I know the answer is $102.20 because since there are 15 members in total I would suggest that you would subtarct by 8 and you would get 7 . Beacuse 8 out of the 15 memebers already payed the first day
So that means 7 memebers have to pay each member has to pay 14.60...
That means 7 memeber times $14.60 will equal $102.20\
Hope this helps!!
Answer:
B. $102.2
Step-by-step explanation:
You will subtract the 8 members who payed their dues on the first day of the month, getting 7 members left to pay their dues. Then you will multiply 7 • $14.60 = $102.2 payed the second day of the month.

Please help me solve Im so confused
Answer:
m<1=117
m<2=99
Step-by-step explanation:
Answer:
Angle 1 is 117 degrees.
Angle 2 is 59 degrees.
Step-by-step explanation:
Let angle 1 be x, and angle 2 be y.
By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.
Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.

Which of the following could represent the question: How many 4/9s are in 6/5 as a multiplication equation?
x*4/9=6/5
x*6/5=4/9
6/5*4/9=x
4/9*6/5=x
Answer:
Select the third answer listed which states: 6/5 * 9/4
Step-by-step explanation:
To find how many of a quantity x are in another quantity y, we normally divide in the following fashion:
y divided by x = y ÷ x = y / x
Then we do the same here: 6/5 divided by 4/9 = 6/5 ÷ 4/9 = 6/5 * 9/4

For the following compound interest problem, how much interest would you earn if you put $600 in the bank at 5.5% for 2.25 year.
Answer:
$74.25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 600 × 0.055 × 2.25 = 74.25
I = $ 74.25
The simple interest accumulated
on a principal of $ 600.00
at a rate of 5.5% per year
for 2.25 years is $ 74.25.

Find the degree measure of each angle in the triangle.
Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.

The drive from savannah to Milwaukee takes approximately 15.5 hours how long is the drive in minutes
Answer: the result is 930 minutes.
Step-by-step explanation:
15.5 hours to minutes has been calculated by multiplying 15.5 hours by 60
The drive from Savannah to Milwaukee takes approximately 930 minutes .
To convert the drive time from hours to minutes, we can multiply the number of hours by 60, as there are 60 minutes in an hour .
Given that the drive from Savannah to Milwaukee takes approximately 15.5 hours, we can calculate the drive time in minutes as follow s:
The time in minutes is equal to the time in hours multiplied by 60 .
15.5 hours = 15.5 hours * 60 minutes/hour .
15.5 hours = 930 minutes .
Therefore, the drive from Savannah to Milwaukee takes approximately 930 minutes .

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online file below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error.
Answer:
A. 384.16
B. 2,401
C. 9,604
D. No
Step-by-step explanation:
Calculation to determine how large a sample should be taken for each desired margin of error
First step is to find σ which represent Population Standard deviation
σ=($50,000-$30,000)/4
σ=$20,000/4
σ = 5,000
Now let calculate how large a sample should be taken for each desired margin of error
Using this formula
n = (Za/2*σ/E)^2
Where,
Za/2=1-0.95/2
Za/2=0.05/2
Za/2=0.025
Z-score 0.025=1.96
Za/2=1.96
σ =5,000
E represent Desired margin of error
Let plug in the formula
a. $500
n = (1.96* 5,000/$500)^2
n=(9,800/$500)^2
n=(19.6)^2
n = 384.16
b. $200
n = (1.96*5,000/200)^2
n=(9,800/$200)^2
n=(49)^2
n = 2,401
c. $100
n = (1.96*5,000/$100)^2
n=(9,800/$100)^2
n=(98)^2
n = 9,604
Therefore how large a sample should be taken for each desired margin of error will be :
A. $500= 384.16
B. $200= 2,401
C. $100= 9,604
d.NO, Based on the information calculation i would NOT recommend trying to obtain the $100 margin of error reason been that it is highly costly compare to $500 margin of error and $200 margin of error.

Simplifying
35 + -1X = 5
Solving
35 + -1X = 5
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-35' to each side of the equation.
35 + -35 + -1X = 5 + -35
Combine like terms: 35 + -35 = 0
0 + -1X = 5 + -35
-1X = 5 + -35
Combine like terms: 5 + -35 = -30
-1X = -30
