Step-by-step explanation:
According the a University Center for Logistics Management, 7% of all merchandise sold in the United States gets returned. A Seattle department store samples 89 items sold in January and found that 10 of the items were returned. H0: p = 0.07 H1: p < 0.07 Calculate the test statistic: Group of answer choices 1.31 2.33 0.99 1.15 1.57
Answer:
The test statistic is 1.57.
Step-by-step explanation:
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A Seattle department store samples 89 items sold in January and found that 10 of the items were returned.
This means that [tex]n = 89, X = \frac{10}{89} = 0.1124[/tex]
7% of all merchandise sold in the United States gets returned.
This means that [tex]\mu = 0.07[/tex]
For a proportion, the standard deviation is [tex]\sigma = \sqrt{p(1-p)} = \sqrt{0.07*(1-0.07)} = 0.2551[/tex]
Test statistic:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.1124 - 0.07}{\frac{0.2551}{\sqrt{89}}}[/tex]
[tex]t = 1.57[/tex]
The test statistic is 1.57.
How to solve 4x+25+10
Answer:
first you would move the x to the other side of the equation so it would be 25+10= -4x next you would add the 25 and the 10 and that would be 35=-4x than you divide 35 by -4 and your answer would be -8.75

Find the point slope equation of the line through (10, -4) with a slope of -6.
Answer:
y=-6x+56
Step-by-step explanation:
The point-slope equation of a line is given as
y=mx+c where m is slope and c is y-intercept of a line.
We are given m=-6 and a point (10,-4) which can be put into y=mx+c to find the only unknown c. Thus,
c=-4+6x10=56.
Now we can easily form the point-slope equation of the line
y=-6x+56.
The population of a town is 30,000, and it grows at a
rate of 7.2% per year.
What will the population be in 6 years?
Answer:
The population in 6 years will be 42,960.
Step-by-step explanation:
First, multiply 7.2% or 0.072 and 30,000 which will give you 2,160.
Then, 2,160 by the number of years (6) which is 12,960.
Lastly add 12,960 and 30,000 to get 42,960.

what is the least whole number that has the remainders 10,12, and 15 when divided by 16, 18. and 21, respectively
Answer:
[tex]1002[/tex]
Step-by-step explanation:
First find difference between the divisors and remainders.
[tex]16-10=6\\18-12=6\\21-15=6[/tex]
Here, the difference between the divisors and remainders is equal.
So, the required number is equal to LCM of [tex](16,18,21)-6[/tex]
[tex]16=2^4\\18=2(3^2)\\21=3(7)[/tex]
LCM of [tex](16,18,21)=2^4(3^2)(7)=1008[/tex]
Required Number [tex]=1008-6=1002[/tex]
What is 2y+4x =10 in y=mx+b
Answer:
The answer should be y = -2x + 5
Step-by-step explanation:
Subtract 4x to move it to the other side.
(2y = -4x + 10)
Then you divide both sides by 2 to get y by itself.

Answer:
5/12
Step-by-step explanation:
Probability of getting either heads or tails of a coin : 1/2
Probability of getting 1,2,3,4, or 6 on a dice: 5/6
Multiply those two probabilities : 1/2 * 5/6 = 5/12
You have a 5 out of 12 chances of getting heads on a coin AND any number but a 5 on a dice.
Hope this helps!

The owner of a ballroom dance studio has 8 locations in the Houston area. Each studio is a 30 foot by 30 ft. room. If each couple requires 72 inch by 72 inch area, what is a reasonable estimate for the total number of people the dance company can accommodate in the city of Houston for all of it's locations?
Answer: 400
Step-by-step explanation:
Area required by each couple = 72 inch by 72 inch
= 6 feet by 6 feet [ 1 feet = 12 inches and [tex]72\text{ inches}=\dfrac{72}{12}\text{ feet}=6 \text{ feet}[/tex]]
= 36 square feet
Area in each studio = 30 ft by 30 ft = 900 square feet
Then, Area of 8 studios in Houstan = 8 x (900 feet) = 7200feet
Total couple the dance company can accommodate in the city of Houston for all of it's locations = [tex]\dfrac{7200}{36}=200[/tex]
Total people = 2 x (Total couples)= 2 x 200=400
Hence, a reasonable estimate for the total number of people the dance company can accommodate in the city of Houston for all of it's locations = 400

Members of a softball team raised $2039.50 to go to a tournament. They rented a bus for $1157.50 and budgeted $49 per player for meals. Write and solve an equation which can be used to determine xx, the number of players the team can bring to the tournament.
Answer:
18 = number of players
Step-by-step explanation:
Giving the following information:
Members of a softball team raised $2039.50 to go to a tournament. They rented a bus for $1157.50 and budgeted $49 per player for meals.
To calculate the total number of players they can bring, we need to use the following formula:
Total amount of money= fixed cost + unitary variable cost*number of players
2,039.5= 1,157.5 + 49*number of players
882/49= number of players
18 = number of players
Answer:
49x+1157.50=2039.50
