Answer:
C. The cost of mailing 10 pounds of books is twice the cost for 5 pounds of books
Step-by-step explanation:
The equation below shows the formula for calculating the shipping cost, C for book orders,
where p is the weight of the books in pounds. There is a $3 handling fee on every order.
C = $0.75p + $3
Which statement is not true about the cost?
A. The cost for shipping books varies according to the weight of the order.
Yes
C = $0.75p + $3
A change in the weight of books changes the cost for shipping the books
B. The cost of mailing books increases by 0.75 for each additional pound of books.
Yes
C. The cost of mailing 10 pounds of books is twice the cost for 5 pounds of books
C = $0.75p + $3
For 10 pounds
C = $0.75p + $3
= 0.75(10) + 3
= 7.5 + 3
C = $10.5
For 5 pounds
C = $0.75p + $3
= 0.75(5) + 3
= 3.75 + 3
C = $6.75
D. The cost of the handling fee is unrelated to the weight of the books.
C. The cost of mailing 10 pounds of books is twice the cost for 5 pounds of books.

The distance from Alison's house to the mailbox is 2/5 mile. The distance from the mailbox to the bus stop is 1/3 mile. What is the total distance from Alison's house to the bus stop? 3/15 11/15 5/6 3/8
Answer:
Option B is correct
Step-by-step explanation:
Given
Distance from Alison's house to the mailbox = [tex]\frac{2}{5}[/tex] miles
Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles
The total distance between Alison's house to the bus stop is
[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]
Hence, option B is correct

A model train is 9 centimeters long. The actual engine is 18 meters long. What is the scale of the model? Tracy has a model train set that is 59 centimeters long. How long would the train be in real life?
Answer:
1 cm : 2m
1 cm = 2m
118m
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
18 / 9 = 2 : 1
59 x 2 = 118

Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change = [tex]\frac{-8-0}{3-1}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4 → C
1. Average Senior High School annual cost of tuition fee for all private schools in Cavite last year was 46,300 a random sample of costs this year for 45 private schools indicated that the sample mean was 47,800 and a sample standard deviation was 5600 at the 0.10 level of significance, is there sufficient evidence to conclude that the cost has increased?
Solution:
1. State of hypotheses
2. The level of significance, critical region, and df if any
3. Compute for the value of one sample z-test or t-test
4. Decision rule
5. conclusion
Answer:
Step-by-step explanation:
H0 : μ = 46300
H1 : μ > 46300
α = 0.05
df = n - 1 = 45 - 1 = 44
Critical value for a one tailed t-test(since population standard deviation is not given).
Tcritical = 1.30
The test statistic :(xbar - μ) ÷ (s/sqrt(n))
The test statistic, t= (47800-46300) ÷ (5600√45)
t = 1500
t = 1500 / 834.79871
t = 1.797
The decision region :
Reject H0: if t value > critical value
1. 797 > 1.30
Tvalue > critical value ; We reject H0
Hence, there is sufficient evidence to conclude that cost has increased.

A soccer ball went on sale from $30 to $24. By what percentage was the price of the
soccer ball reduced?
A. 6%
B. 60%
C. 40%
D. 20%
help me please :,)
Answer:
D. 20%
Step-by-step explanation:
if you subtract 24 from 30 you get 6.
6 times 5 is 30
therefore, 6 is one fifth of 30.
what is 1/5 of 100%?
20%
hope this helps ya out ;)
20 percent of original price reduced. Therefore, option D is the correct answer.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a soccer ball went on sale from $30 to $24.
Reduce in percentage = (Original price - New price)/Original price ×100
= (30-24)/30 ×100
= 6/30 ×100
= 1/5 ×100
= 0.2×100
= 20%
Therefore, option D is the correct answer.
