To find the Unit Rate, you have to divide the amount of money by the amount of whatever the product is
5.99/8= 0.74875
Since the question says to round it to the nearest hundredth, that means the price per unit (unit rate, or the price for one battery here) would be about $0.75. Simple, right?
Simplify:
3(8) 0 • (3) –2
a–27
b24/9
c–216
d 1/3
Answer:
-2a-27b.2^3/3c-2161/3

Recent test scores on the Law School Admission Test (LSAT) are normally distributed with a mean of 162.4 and a standard deviation of 15.9. What is the probability that the mean of 8 randomly selected scores is less than 161?
Answer:
0.40166
Step-by-step explanation:
When given random number of samples, we solve using the z score formula:
z = (x-μ)/σ/√n where
x is the raw score= 161
μ is the population mean = 162.4
σ is the population standard deviation = 15.9
n is random number of samples = 8
Hence,
z = 161 - 162.4/15.9/√8
z = -0.24904
Probability value from Z-Table:
P(x<161) = 0.40166
The probability that the mean of 8 randomly selected scores is less than 161 is 0.40166
The graph of a system of equations will intersect at exactly 1 point?
Answer:
A system of equations can intersect at no points; this is when the lines are parallel, which means they have the same slope and different y-intercept. A system of equations can intersect at one point; this is when the lines have different slopes.

QUESTION 10 of 10: You have a need to purchase 30 units of a product and have them delivered to your company in five days. The sale price is $35 each. Sales tax on the product is 8%. Shipping price is $15. But there is also a 25% rush charge on the sales price added for deliveries less than seven days, which is also taxable. What will be the total cost of this purchase? O a) $1,050.00 b) $1,327.50 Oc) $1,396.50 O d) $1,432.50
Answer: d) $1,432.50
Step-by-step explanation:
Sales price = $35
25% rush charge = 35 * 25% = $8.75
Rush charge is taxable = (35 + 8.75) * 8% = $3.5
Total purchase price per unit = 35 + 8.75 + 3.5 = $47.25
Total cost = Total Purchase + Shipping
= (47.25 * 30) + 15
= $1,432.50

Answer:
C
Step-by-step explanation:
(x+7)(x+1)(x+4)=
x^3+12x^2+39x+28 or C
Answer:
C
Step-by-step explanation:
Given
(x + 7)(x + 1)(x + 4) ← expand the second/ third factors using FOIL
= (x + 7)(x² + 5x + 4)
= x(x² + 5x + 4) + 7(x² + 5x + 4) ← distribute both parenthesis
= x³ + 5x² + 4x + 7x² + 35x + 28 ← collect like terms
= x³ + 12x² + 39x + 28 → C

Answer:x=4
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
Since it's a equilateral triangle, all sides are equal
So you can do the equation 3x - 1 = 11
You then add 1 on both sides, leaving the equation as 3x = 12
You divide both sides by 3, which leaves you with x = 4

The sum of the tens digit and the hundreds digit of a number is three times the units digit. 1/5 of the sum of all three digits is 1 less than the units digit. Find all three-digit numbers that satisfy these conditions.
Answer: The numbers are:
965
875
785
695
Step-by-step explanation:
We have a 3 digit number that can be written as:
a*100 + b*10 + c
Where a, b, and c are single-digit numbers.
a is the hundreds
b is the tens
c is the unit.
We know that:
"The sum of the tens digit and the hundreds digit of a number is three times the units digit."
a + b = 3*c
" 1/5 of the sum of all three digits is 1 less than the units digit."
(a + b + c)/5 = c - 1
Then we have the two conditions:
a + b = 3*c
(a + b + c)/5 = c - 1
From the first one, we can write:
(a + b)/3 = c
Replacing that in the other equation we get:
(a + b + a/3 + b/3)/5 = a/3 + b/3 - 1
(4/3)*(a + b)/5 = (a/3 + b/3) - 1
(4/15)*(a + b) = (a + b)/3 - 1
(4/15)*(a + b) - (a + b)/3 = - 1
-(1/15)*(a + b) = -1
a = 15 - b
Then we can give different values for b, and find the values of a and c, where a and c must be positive.
b = 9
a = 15 - 9 = 6
Then:
c = (9 + 6)/3 = 5
(notice that a + b = 15, then c will be always equal to 5, reggardless of the values of b and a).
This number will be:
695.
if b = 8, then:
a = 15 - 8 = 7
and c = 5, same as before.
the number is 785.
If b = 7, then:
a = 15 - 7 = 8
The number is 875
if b = 6, then:
a = 15 - 6 = 9
The number is:
965

If we find that the null hypothesis, Upper H Subscript 0 Baseline colon beta Subscript j Baseline equals 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should:___________
Answer:
Remove the variable from the Model
Step-by-step explanation:
Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.
Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.
So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.
