Based on a sample survey, a principal claims that 7 out of 10 students like math. If there are 1300 students, how many would you predict do NOT like math?
Answer:
390
Step-by-step explanation:
find the fraction of those that don't like math
10/10 - 7/10= 3/10
then do 3/10 x 1300 to get 390

How might you prove your observations in Question 2 using algebra and x and y-coordinates? Briefly outline an approach using what you know about a midpoint and the slope of a line.
Answer:
I can use variables to represent the coordinates of the vertices for a general triangle, ∆ABC. Then I can calculate the midpoints of the sides in terms of those variables. Using the point-slope formula for the equation of a straight line, I can build the symbolic equations for the three medians, AE, BF, and CD. I can solve for the point of intersection for two of the medians, AE and BF, for example. Finally, I can prove the lines (i.e., medians) concurrent if the point I found also satisfies the equation of the line for CD.

The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers.♀️
Answer:
Smaller number: 12
Larger number: 34
Step-by-step explanation:
Let x represent the smaller number.
Let 3x - 2 represent the larger number (The larger number is two less than three times the smaller number, or x)
x + 3x -2 = 46
Add 3x + x:
4x - 2 = 46
Add 2 to both sides:
4x = 46 + 2
Add 46 + 2:
4x = 48
Divide both sides by 4:
4x/4 = 48/4
x = 12 is the smaller number
Since 12 is the smaller number, and the sum of the two numbers is 46, than the larger number must be 34.

-4(1+ 5-6- (42+5)
I really need the answer asap please and thanksss
Answer:
Read left to right
Do parenthesis first
-4 ( 1 + 5) ^2
-4 (6) ^2
Then exponent
6^2 = 6 x 6 = 36
-4 x 36 = -144
Then divide
-144 / 6 = -24
Then the next parenthesis
(42+5) = 47
-24 - 47 = -71

A homeowner has 32 feet of fencing to build three sides of a rectangular chicken coup. One side of the chicken coup will be against the barn, so the 32 feet of fence will only be used for three sides.
What are the ideal length and width of the chicken coup that would maximize its area?
Answer:
The ideal length is 16 feet
The ideal width is 8 feet
Step-by-step explanation:
The given parameters are;
The length of the fencing available to the homeowner = 32 feet
The number of sides of the rectangular chicken coup the fence will be applied = 3 sides
Let L represent the length and W, represent the width
Therefore, we have;
The perimeter of the fence = 2W + L = 32 feet
L = 32 - 2·W
The area is given by, A = Length, L × Width, W
A = (32 - 2·W) × W = 32·W - 2·W²
Differentiating with respect to W and equating to 0 to find the maximum point gives;
dA/dW = d(32·W - 2·W²)/dW = 0
32 - 4·W = 0
4·W = 32
W = 32/4 = 8
W = 8 feet
Given that the sign of the variable in the equation of the derivative is negative, the value we get is the maximum point
The ideal width W = 8 feet
The length, L = 32 - 2·W = 32 - 2 × 8 = 16 feet
Therefore, the ideal length, L = 16 feet.

1. (MGSE9-12.F.BF.1) This table shows the number of people at a festival at certain times during
the day. Which function best represents the table below?
Hour (PM) 1 2 4 7 8
Number of People 12 19 33 54 61
A. f(x) = 7x + 12
B. f(x) = 7x + 5
C. f(x) = 5x + 7
D. f(x) = 5x + 12
Answer:
[tex] f(x) = 7x + 5 [/tex].
Step-by-step explanation:
The equation that represents the function can be written in the slope-intercept form, [tex] f(x) = mx + b [/tex].
To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.
First, calculate the slope of the function using two points, (1, 12) and (2, 19).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{19 - 12}{2 - 1} = \frac{7}{1} = 7 [/tex]
Next, find b by substituting x = 1, f(x) = 12, and m = 7 into [tex] f(x) = mx + b [/tex].
[tex] 12 = (7)(1) + b [/tex]
[tex] 12 = 7 + b [/tex]
Subtract 7 from each side
[tex] 12 - 7 = b [/tex]
[tex] 5 = b [/tex]
[tex] b = 5 [/tex]
Substitute m = 7 and b = 5 into [tex] f(x) = mx + b [/tex].
✅Thus, the equation that represents the function would be:
[tex] f(x) = 7x + 5 [/tex].

A line passes through the points(4,10) and (9,20) Write a linear function in terms of X and Y for this line
Answer:
y = 2x + 2
Step-by-step explanation:
given : line passes through the points (4,10) and (9,20)
Required : write a linear function in terms of x and y
solution :
substitute the coordinate points into the equation: y = mx + b
(x=9, y=20) _ 20 = 9m + b
(x=4, y=10) 10 = 4m + b
subtracting 10 = 5m
m = 10/5
m = 2
substitute x=2 back into eq.1 to solve for b
20 = 9m + b
20 = 9(2) + b
20 - 18 = b
b = 2
therefore the straight line equation is:
y = mx + b
y = 2x + 2
Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)
Answer:
? = 9
Step-by-step explanation:
you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!
hope this helps!
Explain at least one way solving an
inequality is different than solving an
equality.
Answer:
Inequalities are used to demonstrate relationships between numbers or expressions. An inequality describes a relationship between two different values.
The notation
a
<
b
means that
a
is strictly smaller in size than
b
, while the notation
a
>
b
means that
a
is strictly greater than
b
.
The notion
a
≤
b
means that
a
is less than or equal to
b
, while the notation
a
≥
b
means that
a
is greater than or equal to
b
.
Inequalities are particularly useful for solving problems involving minimum or maximum possible values.
