Answer:
B-Tickets
B-15x-500≥1000
C-x≥100
Step-by-step explanation:
X is the variable because you need to find how many tickets need to be sold
The answer is B because they need to raise $1000 or more
15x-500≥1000 (add 500 to both sides)
15x≥1500
x≥100
A researcher wishes to determine whether there is a difference in the average age of elementary school, high school, and community college teachers. Teachers are randomly selected. Their ages are recorded below. A suitable hypothesis test will be conducted to test the claim that there is no difference in the average age of each group. Find the test statistic. g
Answer:
F- test
Step-by-step explanation:
Testing the hypothesis about the equality of k (k>2) population means
Test statistic F is used to find the whether there is no difference in the average age of each group.
Test statistic to be used
F= Between Mean Square/ Within Mean Square
F= s1²/s2² where s1 and s2 are independent unbiased estimates of the variance and their values do not differ greatly.
Which have v1= k-1 and v2= n-k degrees of freedom
The analysis of variance F -t est is always a one tailed test with rejection region located in the right tail of the F- distribution.
Is the first one correct and what are the ages?

Choose all the weights that are equal to 1 ton 200 pounds.
A.
35,000 ounces
B.
1,200 pounds
C.
2,200 pounds
D.
1,200 pounds 100 ounces
E.
1 ton 100 pounds 1,600 ounces please answer this
Answer:
C. and E. i did the test
Step-by-step explanation:
The only options that are equal to 1 ton 200 pounds are C and E.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We are given that;
1 ton 200 pounds.
Now,
We can compare this value with the given options and see which ones are equal to it. We can use the conversion factors from the search results34 to convert ounces to pounds. We get:
A. 35,000 ounces = 35,000 / 16 pounds 35,000 ounces = 2,187.5 pounds This is not equal to 2,200 pounds.
B. 1,200 pounds = 1,200 pounds This is not equal to 2,200 pounds.
C. 2,200 pounds = 2,200 pounds This is equal to 2,200 pounds.
D. 1,200 pounds 100 ounces = (1,200 + (100 / 16)) pounds 1,200 pounds 100 ounces = (1,200 + 6.25) pounds 1,200 pounds 100 ounces = 1,206.25 pounds This is not equal to 2,200 pounds.
E. 1 ton 100 pounds 1,600 ounces = ((1 x 2,000) + (100 + (1,600 / 16))) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + (100 + 100)) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + 200) pounds 1 ton 100 pounds 1,600 ounces = 2,200 pounds This is equal to 2,200 pounds.
Therefore, by the conversion the answer will be 1 ton 200 pounds are C and E.

d-I don't know what u were asking 423/4,000 is 0.10575
Step-by-step explanation:
Finding decimals from fractions is easy just divide the top number by the bottom a fraction sign is the same as a division sign I don't know why you use the other one with the dots on both sides instead of just always using this one.
1) you deposit $2,300 in a bank account. find the balance after 5 years for each of the following situations: is) the account pays 2.5% annual interest compounded monthly.
Answer:
Well, After 5 years No interest you'd still have only 2,300 dollars in the bank.
But 5 years with interest you'd have 5750$ in the bank.
Step-by-step explanation:
With no interest, their is nothing added to your bank account, if you don't take anything away from it either then you'd still have the exact same amount.
With 2.5% monthly interest you'd get 3250$ because...5years * 12 months = 60 months...60 months * 2.5% = 150%...2,300$ + 150% = 5750$.

Which statement is true about the relationship between the height of the plant and the number of days? This relationship is a function because the plant can only be one height at a time. This relationship is not a function because the plant can only be one height at a time. This relationship is a function because the plant can be more than one height at a time. This relationship is not a function because the plant can be more than one height at a time.
Answer:
This relationship is a function because the plant can only be one height at a time.
Step-by-step explanation:
Functions occur when the recorded x-value is varied each time. Since the height of the plant (the x-value) varies each day, it is a function.

Is the point (-4, 1/2) on the graph of y= 1\2 x-4 ? How do you know? Show your work/thinking.
9514 1404 393
Answer:
no, when x is even, y will be an integer, not a fraction
Step-by-step explanation:
We observe that the coefficient of x is 1/2, so the x-term will be an integer only if x is a multiple of 2 (even). If the x-term is an integer, y will be an integer.
The given point has x even (-4), so we expect y to be an integer. The given point has y=1/2, not an integer, so the point will NOT be on the graph.
