the average rate of change of the function f(x) on the interval -3≤x≤3 is -2.5. If (-3)=14 then which of the following is the value of f(3)?
The average rate of change of f(x) on -3 ≤ x ≤ 3 is given to be
(f (3) - f (-3)) / (3 - (-3)) = -2.5
If f (-3) = 14, then
(f (3) - 14) / (3 + 3) = -2.5
(f (3) - 14) / 6 = -2.5
f (3) - 14 = -15
f (3) = -1

Craig works at a restaurant for 21 hours in January. at this rate, how many hours will he work after 7.5 months?
Answer:
around 4725
Step-by-step explanation:
Answer:
157.5 hours
Step-by-step explanation:
If Craig continued to work 21 hours for 7.5 months he would work a total of 157.5 hours.
Why?
Because if you multiply 21 seven times you get a total of 147 hours, but we still have the .5 of the month so take 21 and divide it by 2 which gives us 10.5 hours.
When you have both you outcomes ready you add 147 and 10.5 hours
Which gives us 147+10.5=157.5 hours.
Good luck :)
Ravi purchased 3 DVDs for $19.99 each. Find the total cost for the DVDs including 5% GST and 6% PST.
Answer:
$66.57
Step-by-step explanation:
Cost of one DVD = $19.99
Cost of 3 DVDs = $19.99*3 =$59.97
Rate of GST = 5%
Amount of GST
= 5%* $59.97
= 0.05*59.97
= $2.9985
Rate of PST = 6%
Amount of PST
= 6%* $59.97
= 0.06*59.97
= $3.5982
Total cost of DVDs
= $59.97 + $2.9985 + $3.5982
= $66.5667
= $66.57

A recent Gallop poll showed that 672 of 1019 adults nationwide think that marijuana should be legalized. a) Find the margin of error that corresponds to a 95% confidence interval.
Answer:
the margin of error is 0.029
Step-by-step explanation:
The computation of the margin of error is as follows;
Point estimate = sample proportion
[tex]= \hat p[/tex] = x ÷ n = 672 ÷ 1019 = 0.659
Now
= 1 - [tex]\hat p[/tex]
= 1 - 0.659
= 0.341
[tex]Z\alpha/2[/tex] = Z_0.025 = 1.96
Now
a) Margin of error = E is
[tex]= Z\alpha / 2 \times \frac{((\hat p \times (1 - \hat p ))}{(\sqrt / n)} \\\\= 1.96 (\sqrt \frac{ (0.659 \times 0.341)}{(1019)} \\\\= 0.029[/tex]
Hence, the margin of error is 0.029

Belle's dad lends her $10. Then Belle borrows another $15 from him. Write and evaluate an expression that shows the change in the amount of money Belle's dad has.
The expression that shows the change in the amount of money Belle's dad has is (x - 25) and this can be determined by forming the linear equation in one variable.
Given :
Belle's dad lends her $10. Then Belle borrows another $15 from him.
The following steps can be used to determine the expression that shows the change in the amount of money Belle's dad has:
Step 1 - Let the total amount of money Belle's dad have be 'x'.
Step 2 - Then it is given that Belle's dad lends her $10. So the expression becomes:
= x - 10b
Step 3 - Now, it is also given that Belle borrows another $15 from her dad. So, the above expression becomes:
= x - 10 - 15
Step 4 - Simplify the above expression.
= x - 25
So, the expression that shows the change in the amount of money Belle's dad has is (x - 25).

Answer:
H) Slope -1/4 and y-intercept -1.5
Step-by-step explanation:
The slope of the line is determined by the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
We can use any two points on the line lets use the ones that are shown, (-6 , 0) and (2 , -2).
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-2-0}{2-(-6)} \\\\m=\frac{-2}{8}\\\\m=-\frac{1}{4} \\[/tex]
and the y-intercept is shown in the graph where the line crosses the y-axis
In this case the line crosses the y-axis between -1 and -2 which is -1.5
so the value of slope is -1/4 and the value of y-intercept is -1.5 .So third option is our answer.

which equation is equivalent to the formula below?
Y = A ( X - H) ^2 + K
Answer:
B. a = y - k/(x-h)²
Step-by-step explanation:
Given the expression y = a (x-h)² + k
First make a the subject of the formula
Subtract k from both sides
y = a (x-h)² + k
y- k = a (x-h)² + k - k
y - k = a (x-h)²
Divide through by (x-h)²
y - k/(x-h)² = a
a = y - k/(x-h)²
Hence option B is correct
Answer:
a=y-k/(x-h)^2

Antonio completed the right column of the table to help him find the sum of 2/ and 1/5.
In which step did his first error occur?
Step ( )
Answer:
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Step-by-step explanation:
In order to add or subtract two fractions, a common denominator is found and then the denominators of both fractions are made equal to the common denominator.
The given fractions are:
[tex]\frac{2}{9}\ and\ \frac{1}{5}[/tex]
The common denominator is the number which is the multiple off denominators of both fractions involved.
Antonio made his first error in first step. Instead of finding a common multiple denominator, he add the denominator of both fractions which is wrong.
The correct method is:
[tex]\frac{2}{9} + \frac{1}{5}\\= \frac{2*5}{9*5} + \frac{1*9}{5*9}\\=\frac{10}{45}+\frac{9}{45}\\=\frac{19}{45}[/tex]
Hence,
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
