153.86 square units
Step-by-step explanation:
The radius of the circle is 7 units. The area is given by ...
A = πr²
A = (3.14)(7²) = 153.86 . . . . square units
The area of the circle is about 153.86 square units.
The equation of the line that goes through the point ( 3 , 4 ) and is parallel to the line 3 x + 4 y = 2 can be written in the form y = m x + b
Answer:
y = -3x/4 + 25/4
Step-by-step explanation:
3x + 4y = 2
-3x -3x
4y= -3x + 2
4y/4 = -3x/4 + 2/4
y = -3x/4 + 1/2 mx= -3x/4
y = -3x/4 + ?
-3x/4 = Right 4, Down 3 on a graph
( 3, 4)
-4 +3
Also goes thru the point (-1, 7)
+1 -3/4
(0, 25/4 or 6.25)
y = -3x/4 + 25/4

What is the mean absolute deviation of the data: 3, 7, 8, 12, 16, 18 of each number. I tried to take a picture but it is too blurry. But pls hurry hurry!!!
Answer:
[tex]M = 4.67[/tex]
Step-by-step explanation:
Given
[tex]Data: 3, 7, 8, 12, 16, 18[/tex]
Required
The mean absolute deviation
Start by calculating the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{3+ 7+ 8+ 12+ 16+ 18}{6}[/tex]
[tex]\bar x = \frac{64}{6}[/tex]
[tex]\bar x = 10.67[/tex]
The mean absolute deviation is then calculated using:
[tex]M = \frac{1}{n}\sum\limits^n_{i=1}|x _i - \bar x|[/tex]
So, we have:
[tex]M = \frac{1}{6}(|3 - 10.67| +|7 - 10.67| + |8 - 10.67| + |12 - 10.67| + |16 - 10.67| + |18 - 10.67|)[/tex]
[tex]M = \frac{1}{6}(|-7.67| +|- 3.67| + |-2.67| + |1.33| + |5.33| + |7.33|)[/tex]
Remove absolute brackets
[tex]M = \frac{1}{6}(7.67 +3.67 + 2.67 + 1.33 + 5.33 + 7.33)[/tex]
[tex]M = \frac{1}{6}*28[/tex]
[tex]M = 4.67[/tex]

The diagram shows a playground in the shape of a trapezium.
50 m
U
32m
90 m
Work out the area of the playground.
Answer:
[tex] 2240 {m}^{2} [/tex]Step-by-step explanation:
Given,
Parallel sides of the trapezium = 50m, 90m
Height of the trapezium = 32m
Therefore,
Area of the trapezium
[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \: \times \: height[/tex]
[tex] = \frac{1}{2} \times (50 + 90)m \times 32m[/tex]
= (50 + 90) m × 16m
= 140m × 16m
[tex] = 2240 {m}^{2} (ans)[/tex]
Answer:
A = 2240 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 32 , b₁ = 90 and b₂ = 50 , then
A = [tex]\frac{1}{2}[/tex] × 32 × (90 + 50) = 16 × 140 = 2240 m²

Morris climbs up a fruit tree and tosses a pear to his brother. The graph shows the height of the pear as a function of x, the distance of the pear from the tree. What is the range for this situation?
Answer:
Range → {7, 9, 0}
Step-by-step explanation:
Range of a function is a set of y-values or output values of the function.
Similarly, Domain of a function is the set of x-values or input values of the function.
Given points in the graph are (0, 7), (3, 9) and (9.4, 0)
Therefore, set of y-values {7, 9, 0) will be the Range.
Range of the function → {7, 9, 0}
The volume of a box(V) varies directly with its length(l). If one of the boxes has a volume of 325 cubic inches and a length of 13 inches, what is the constant of proportionality for the group of boxes?
1/25
4,225
25
Answer:
k = 25
Step-by-step explanation:
Given the following data;
Volume = 325 in³
Length = 13 inches
To find the constant of proportionality, k;
Mathematically, direct proportion is given by the expression;
V = kL
k = V/L
Substituting into the formula, we have;
k = 325/13
k = 25

Based on these results, express the probability that a seventh grader chosen at
random will play the drums as a decimal to the nearest hundredth.
Answer:12/77
Step-by-step explanation:
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is 0.76.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The total event for seventh grade is given as,
Total = 9 + 9 + 11 + 9
Total = 38
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is calculated as,
P = 9/38 + 11/38 + 9/38
P = 29/38
P = 0.76

If you have $4.00, how many pounds of apples can you buy?
A. 7 pounds
B. 7/4 of a pound
C. 4/7 of a pound
D. 2 2/7 pounds
Answer:
[tex]2 \frac{2}{7}[/tex] pounds, D
Step-by-step explanation:
1 pound of apples = 1.75 dollars.
Set the number of pounds of apples as x.
Then, we can write this equation.
1.75x = 4
[tex]\frac{7}{4}[/tex]x = 4
Divide both sides by [tex]\frac{7}{4}[/tex]
x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]
x = [tex]\frac{16}{7}[/tex]
x = [tex]2 \frac{2}{7}[/tex]
Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds

a gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month. find the price per wind chime that will maximize revenue.
Answer:
The price per wind chime that will maximize revenue = $ 315
Step-by-step explanation:
Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.
To find - Find the price per wind chime that will maximize revenue.
Proof -
Given that,
Total Wind chimes selling = 160
Price of each Wind chime = $150
Now,
Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.
So,
Let the price = 150 + 15x
So,
Number of wind Chimes sold per month = 160 - 5x
So,
Total Revenue, R = (150 + 15x)(160 - 5x)
= 24000 - 750x + 2400x - 75x²
= 24000 + 1650x - 75x²
⇒R(x) = 24000 + 1650x - 75x²
Differentiate R with respect to x , we get
R'(x) = 1650 - 150x
Now,
For Maximize Revenue, Put R'(x) = 0
⇒1650 - 150x = 0
⇒150x = 1650
⇒x = 1650/150
⇒x = 11
∴ we get
Price per Wind chime = $ 150 + 15(11)
= $ 150 + 165
= $ 315
So,
The price per wind chime that will maximize revenue = $ 315
