Answer:
y = -5/2x + 6

y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b
The Table below is a data set that lists how many pairs of shoes are owned by some of your classmates.
Using the data set, what is the median?
Answer:
7.5
Step-by-step explanation:
To find the median, first order the numbers from least to greatest:
2, 4, 5, 7, 8, 8, 10, 12
Then, find the middle number (number in the middle):
There are 2 middle numbers. 7 and 8.
Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.
To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;
7 + 8 = 15
15 / 2 = 7.5

Answer:
y = (x - 2)² - 9
Step-by-step explanation:
Using the method of completing the square
add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 - 5

fred has 15000 in his savings account with an interest rate of 1.8%. assuming he doesn't add or subtract from this amount, find the estimated account balance after 22 years
Answer:
A = $20,940
Step-by-step explanation:
Interest = Principal x Rate x Time
I = prt
I = 15000(.018)(22)
I = 5940
Interest = $5,940
Total Amount = Principal + Interest
A = P + I
A = 15000 + 5940
A = 20940
Point A(2, 5) is dilated from the origin with scale factor 3 , resulting in point A′ . Darius says the coordinates of point A′ are (6, 15) . Marcia says the coordinates of point A′ are (4, 13) . Who is correct?
Answer:
It actually doesn't matter! The key thing is that the dilation value affects the distance between two points. As in the first example (dilation by a factor of 3), A is originally 1 unit down from P and 2 units to the left of P.
1*3 = 3, so A' (the dilated point) should be 3 units down from P.
2*3 = 6, so A' should be 6 units to the left of P.
It doesn't matter if you go left first or down first, because you always determine the location of A' with respect to P based on the location of A (which doesn't move) with respect to P.

13. A bag contains 8 red marbles, 4 purple marbles, 5 green marbles, 2 orange, and 1 blue
marbles. One marble is selected and replaced. A second marble is selected. Find the
probability of each compound event. Show work and simplify your solutions.
a)
Not selecting an orange marble and then a blue marble
b)
Selecting a green or red marble and then a purple marble
Answer:
a) 9 / 200
b) 13 / 100
Step-by-step explanation:
a) The two events are independent because they do not depend each other since the marbles are replaced. To find the total probability of two independent events, you multiply the probability of each event together.
Probability is represented by the amount of desirable outcomes over the total number of outcomes. The total would be the number of marbles, which is: 8 + 4 + 5 + 2 + 1 = 20 outcomes. The number of orange marbles is 2, so the outcomes where you do not pick orange are 20 - 2 or 18 outcomes. The probability of not picking an orange marble would be 18 / 20 or 9 / 10 (using the formula for probability).
There is one outcome where we can pick a blue marble, so the probability of picking a blue marble is 1 / 20. Now, we need to multiply the probabilities for each event: 1 / 20 * 9 / 10 = 9 / 200
b)There are 5 green marbles and 8 red marbles, so the the total outcomes where you pick green or red is 13. We put that over our total to get 13 / 20.
There are 4 purple marbles, so the probability of picking purple is 4 / 20 or 1 / 5. Now we multiply the two probabilities to get the total probability: 1 / 5 * 13 / 20 = 13 / 100
Find the area of the circle. Leave your answers in terms of pi.
Answer:
49pi m^2
Step-by-step explanation:
Area of circle=pi r^2

r=7
Area of circle =7^2pi=49pim^2
Answer:
Step-by-step explanation:
The diameter = 14m
r = d/2
r = 14/2
r = 7
Area = pi * r * r

Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -5 to -4, it increases = [-5, -4]
For x = 1 to 3, it increases = [1, 3]
Answer: [-5, -4] , [1, 3]

Answer:
145
Step-by-step explanation:
Supplementary angles add up to equal 180 degrees
Thus, ∠ABC + ∠DEF = 180°
If ∠ABC = 35
Then 35 + ∠DEF = 180
180 - 35 = 145
Hence, ∠DEF = 145

Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in, high. Her paper is 12 in, wide and 24 in. tall. She decides to use the scale 1 in. = 4
in. Is this a reasonable scale?
Step-by-step explanation:
1:4=.25 or 25%
so 12/47=.25 or 25%
24/120=.2 or 20%
that ratio does not match the height ratio
Sarah's scale is reasonable.
What is a scale drawing?
A scale drawing is a smaller diagram in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.
Is Sarah's scale reasonable?The first step is to determine the how larger the paper is in terms of the painting.
48 / 12 = 4
120 / 24 = 5
This makes her scale of 1 in to 4 in reasonable.

PLEASE HELP ME ASAP!!! Alex has 64 cubes with dimensions in feet like the one shown. (1/2 ft). He uses all the cubes to fill a box shaped like a larger rectangular prism. What is the volume, in feet, of the larger rectangular prism?
Answer: MARK AS BRAINLIST PLZ:)
A) First, find the volume of each cube:
V = s³
= (1/2)³
= 1/8 ft³
We have a total of 64 cubes, therefore the maximum volume will be:
Vmax = 64 · (1/8) = 8 ft³
B) The volume of a rectangular prism is given by:
V = w × l × h
Therefore any combination of w × l × h = Vmax = 8 will be fine.
Examples:
2 × 2 × 2
4 × 2 × 1

Find the area of the figure.
9514 1404 393
Answer:
7 square inches
Step-by-step explanation:
We take the "3 in" dimension at the left to be the length of the line segment below the 1" square, so the height of the right triangle is 3+1 = 4 in.
The triangle area is ...
A = 1/2bh
A = 1/2(3 in)(4 in) = 6 in²
The square area is ...
A = s²
A = (1 in)² = 1 in²
Then the total area of the figure is ...
1 in² + 6 in² = 7 in²

At a point on the ground 50 feet from the foot of a tree, the angle of
elevation to the top of the tree is 53 degrees. Find the height of the tree.
Round to the nearest hundredths.
Answer:
66.35 feet
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent
= tan θ = Opposite/Adjacent
θ = 53°
Opposite = Height of the tree = h
Adjacent = Point of the ground from the foot of the tree = 50 ft
Hence,
tan 53 = h/50ft
Cross Multiply
h = tan 53 × 50ft
h = 66.352241081 ft
Approximately to the nearest hundredth, the height of the tree = 66.35 feet
