Answer:
25
Step-by-step explanation:
Given the model:
y=−3.5x+400
Number of children in amusement park = y
Temperature = x
On a certain day:
Temperature = 90°F
Number of children in park = 60
Using the model :
The predicted number of children in park when temperature is 90°F would be :
y = - 3.5(90) + 400
y = - 315 + 400
y = 85
Model prediction = 85 children
Actual figure = 60
Residual :
|Actual - predicted | = |60 - 85| = 25 children

leah makes a guaranteed salary of $200 per week. but is paid commission of 15% of total sales per week. how much would leah make in a week in which she made $225 in sales?how much would leah make in a week if she made x dollars in sales
Answer:
Total earned with $225 sales = $233.75
Total earned with x sales = 0.15x+200
Step-by-step explanation:
Given that:
Base salary of Leah per week = $200
Commission paid = 15%
Sales made by Leah = $225
Commission = 15% of 225
Commission = [tex]\frac{15}{100} * 225[/tex]
Commission = 0.15 * 225
Commission = $33.75
Total earned = 200 + 33.75 = $233.75
Commission when sales are x
Commission = 0.15x
Total earned = 0.15x+200
Hence,
Total earned with $225 sales = $233.75
Total earned with x sales = 0.15x+200

Ocean water freezes at about -2 1/2 so silly fresh water freezes at zero anti-freeze a liquid used in radiators of cars freeze at -64 imagine if the temperature has dropped to the freezing point for ocean water how many degrees more most the temperature Drop for the anti-freeze to turn solid
Answer:
Temperature needs to drop by 61.5°
Step-by-step explanation:
Given that:
Freezing temperature of ocean water = - 2.5
Freezing temperature of fresh water = 0
Freezing temperature = anti-freeze = - 64
If temperature has dropped to freezing point for ocean water, then current temperature = - 2.5
How many more degrees must the temperature drop for temperature to turn solid :
Freezing temperature of anti-freeze - current temperature
-64 - (-2.5)
-64 + 2.5
-61.5
-61.5(the temperature needs to drop by 61.5°)

Answer:
Step-by-step explanation:
plug 20 in for c
f = 1.8(20) + 32
simplify
f = 36 + 32
f = 68

Whats the value? of this equation
Answer:
Option (4)
Step-by-step explanation:
Given equation of the linear graph is,
[tex]y=-\frac{5}{8}x+\frac{2}{3}n[/tex]
By comparing this equation with the slope-intercept form of the linear equation,
y = mx + b
m = [tex]-\frac{5}{8}[/tex]
And b = [tex]\frac{2}{3}n[/tex]
Since, y-intercept 'b' = -12 [given]
[tex]\frac{2}{3}n=-12[/tex]
n = [tex]-12\times \frac{2}{3}[/tex]
n = -8
Therefore, Option (4) will be the answer.

What type of function is y=2^x +8
Answer:
y = 2ˣ + 8 represents the exponential function.
The graph of the function y = 2ˣ + 8 is also attached below.
Step-by-step explanation:
We know that the general exponential function is of the form
f(x) = aˣ
were a > 0
Given the function
y = 2ˣ + 8
Comparing with y = aˣ, it is clear that the function y = 2ˣ + 8 represents the exponential function.
where a = 2
We can also determine the y-intercept of y = 2ˣ + 8 by setting x = 0, and determining the corresponding value of y.
i.e.
y = 2ˣ + 8
y = 2⁰ +8 ∵ 2⁰= 1
y = 1+8
y = 9
Thus, (0, 9) represents the y-intercept of the exponential function y = 2ˣ + 8.
Therefore, y = 2ˣ + 8 represents the exponential function.
The graph of the function y = 2ˣ + 8 is also attached below.

Each of the following four large congruent squares is
subdivided into combinations of congruent triangles or
rectangles and is partially shaded. What percent of the total
area is partially shaded?
I
The original problem
and choices from the
2011 AMC 8 contest
(A) 12 (B) 20
(C) 25 (D) 33 (E) 37
Answer:
[tex]\mathrm{C.\:}25[/tex]
Step-by-step explanation:
Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are [tex]16[/tex] of these parts in total. Because each of these parts make up [tex]\frac{1}{4}[/tex] of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.
The top left and bottom right both have one part shaded each for a total of [tex]2[/tex] parts.
The top right and bottom left have [tex]0.5[/tex] and [tex]1.5[/tex] parts shaded, respectively, for a total of [tex]2[/tex] parts.
Therefore, in total, there are [tex]2+2=4[/tex] parts shaded out of [tex]16[/tex] total parts.
Thus, the percentage of the total area that is shaded is:
[tex]\frac{4}{16}=\frac{1}{4}=\fbox{$25\%$}[/tex].

3. Find the slope and y-intercept of the graph of the following equation.
2y + 4 = -6x
Answer:
slope= -3,y - intercept y = -2
Step-by-step explanation:
- Make y the subject by taking four on the opposite side of the equal sign.
2y = -6x - 4
- Divide throughout by 2 and from there you get the gradient which is also the slope.
- To get the y - intercept,the value of x =0. Thus you get y =-2.

Bradley has ordered a steak from the meat market that weighs 1 5/8 pounds. There is a bone in the steak that weighs 7/8 of a pound. How much does the meat weigh?
Answer:
3/4
Step-by-step explanation:
the bone and the steak weigh = 1 5/8 pounds
The bone weighs 7/8
The meat weighs = 15/8 - 7/8
Converting 1 5/8 to an improper fraction gives 13/8
13/8 - 7/8 = 6/8 = 3/4
