Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).
Answer:
the median score would be between 510 and 520
Step-by-step explanation:
The computation of the median score is shown below
In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it
Here
P(X = median) = 0.5 = 50%
So the median score would be between 510 and 520
Hence, the same is to be considered
A baker sells bread for $3 a loaf and rolls for $1 each. The baker needs to sell $12 worth of baked goods by
the end of the day.
Use the graph to approximate how many loaves of bread the baker must sell if 6 rolls are sold, where b is
the number of loaves of bread and r is the number of rolls.
Answer:
2 loaves of bread
Step-by-step explanation:
3b + r = 12
3b + 6 = 12
b = 2
Answer:
2

Answer:
1) -[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Between 1 whole, there are four lines in it. Thus:
4 lines --- 1 whole
1 line --- [tex]\frac{1}{4}[/tex]
P is at the 3rd line from zero, so its value is [tex]\frac{1}{4}[/tex] × 3 = [tex]\frac{3}{4}[/tex]
Thus, the opposite of P would be -[tex]\frac{3}{4}[/tex].
Answer:
-1/4
Step-by-step explanation:
This is your answer because when you turn the -1/4 to a decimal and you check it on the line it will give you the same point as P is.
Hope this help:)

Which functions are even? Check all of the boxes that apply.
f(x) = x2 – 3x + 2
7x) = -2)
f(x) = |x|
Answer:
C) f(x) = |x|
Step-by-step explanation:
Determine if Odd, Even, or Neither
f (x) = |x|
Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|
Make −x positive.
f(−x) = |x|
A function is even if f(−x) = f(x).
Check if f(−x) = f(x).
|x| = |x|
Since |x| = |x|, the function is even.
If a rectangle has the sides 5x-3 and 6x-4 what is the area and perimeter
Step-by-step explanation:
[tex]A = lw[/tex]
[tex]A=(5x-3)(6x-4)[/tex]
[tex]A=30x^2-20x-18x+12[/tex]
[tex]A=30^2-28x+12[/tex]
[tex]P=2(l + w)[/tex]
[tex]P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14[/tex]
Answer:
[tex]Perimeter = 22x - 14[/tex]
[tex]Area = 30 {x}^{2} - 38x + 12[/tex]
Step-by-step explanation:
Length of rectangle (l) = 5x - 3
Weidth of rectangle (w) = 6x - 4
Perimeter of the rectangle = [tex]2(l + w)[/tex]
[tex] = > 2(5x - 3 + 6x - 4)[/tex]
[tex] = > 2(11x - 7)[/tex]
[tex] = > 22x - 14[/tex]
Area of the rectangle = [tex]l \times w[/tex]
[tex] = > (5x - 3)(6x - 4)[/tex]
[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]
[tex] = > 30 {x}^{2} - 20x - 18x + 12[/tex]
[tex] = > 30 {x}^{2} - 38x + 12[/tex]

f(t) = 2t - 3 f(7) =
Answer:
f(7) = 11
Step-by-step explanation:
t = 7, so we can just plug in the value 7 for (t) in the given equation.
f(t) = 2t - 3
f(7) = (2 × 7) - 3
f(7) = 14 - 3
f(7) = 11

6x + 3
E 17
G
8x-1
C
Answer:
x=8
Step-by-step explanation:
Triangle DCE is similar to EGF
CE/EF=DE/EG
Substitute
(8x-1)/21=(6x+3)/17
Cross multiply
(8x−1)*(17)=(6x+3)*(21)
136x−17=126x+63
Subtract 126x from both sides
10x−17=63
Add 17 to both sides.
10x−17+17=63+17
10x=80
Divide both sides by 10.
x=8
Earl runs 50 meters in 20 seconds. How many meters does Earl run per second?
Answer:
2.5 meters
Step-by-step explanation:
Answer:
Earl can run 2.5 meters in one second.
Step-by-step explanation:
We know that Earl can run 50 meters in 20 seconds. That means he can run 150 meters in one minute and 9,000 meters (or 9 kilometers) in one hour. 50 meters / 20 seconds = ? meters / 1 second
50 meters / 20 seconds = x / 1 second
(50 x 1) = (20) (x)
50 = 20x divide both sides by 20 to get the "x" alone
50 / 20 = x
2.5 = x

Answer:
Hey mate!
Here is your answer > >
C.P of an article=Rs.400
S.P.of an article=Rs.336
C.P.> S.P., there is a loss
Loss=C.P.-S.P.
=> Loss=400-336
=Rs.64
Loss%=Loss/C.P.×100
=64/400×100
=16%
