Bill spent a total of $35 at the grocery store. Of this amount, he spent $28 on fruit. What percentage of the total did he spend
on fruit?
Answer:
80%
Step-by-step explanation:
28/35 as a percent =
First, simplify the fraction.
28/35 = 4/5
Next, turn the simplified fraction into a denominator of 100.
4/5 = 80/100
80/100 = 80%

Which compares the medians of the data?
The median for the students is 4 and the median for the teachers is 8.
The median for the students is 2 and the median for the teachers is 3.
The median for the students is 4 and the median for the teachers is 3.
The median for the students is 2 and the median for the teachers is 8.
Answer: The median for the students is 2 and the median for the teachers is 3.
Step-by-step explanation:
Ordering the data for the students from the dot points:
0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4.
n = 20 which is positive so median position is average of:
= (n / 2) and = (n + 1) / 2
= 20 / 2 = 21 / 2
= 10 = 10.5
2 is in position 10 2 is in position 10.5
Average = (2 + 2) / 2 = 2
Student median is 2.
Teachers
0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8
3 is in position 10 as well as in position 10.5.
= (3 + 3) / 2
= 3
Teacher median is 3.

Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each tool contains 10 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. An inspector chooses 2 part(s) from among the 10 at random. Two cavities are affected by a temperature malfunction that results in parts that do not conform to specifications.
a. How many samples contain exactly 1 nonconforming part?
b. How many samples contain at least 1 nonconforming part?
Answer:
16 ;
17
Step-by-step explanation:
Number of cavities = 10
Number of parts chosen = 2
Number of cavities affected by temperature malfunction = 2
A.)
Number of samples that contain exactly one conforming part :
2C1 * 10-2C2-1
2C1 * 8C1
Combination formula :
nCr = n! ÷ (n-r)! r!
Using calculator :
2C1 * 8C1 = 2 * 8 = 16
B)
b. How many samples contain at least 1 nonconforming part?
10C2 - 8C2 = 45 - 28 = 17

11. In rhombus MATH, MS = 6 and SA = 8. Find the perimeter of the rhombus.
M
А
8
A
S
I
T
Answer:
40
Step-by-step explanation:
A rhombus diagonals form perpendicular angles. It also bisects and form 4 right triangles. Looking at triangle MAS, we can use pythagorean theorem to find the side MA.
[tex]ms {}^{2} + sa {}^{2} = {ma}^{2} [/tex]
ms=6, sa =8 so we plug that in.
[tex]6 {}^{2} + {8}^{2} = ma {}^{2} [/tex]
Simplify
[tex]36 + 64 = ma {}^{2} [/tex]
[tex]100 = ma {}^{2} [/tex]
take sqr root
[tex] \sqrt{100} = ma[/tex]
[tex]ma = 10[/tex]
Now let find the perimeter
Since perimeter of a Rhombus is 4a where a is the length of a side. We plug it in
[tex]4(10) = 40[/tex]
The answer is 40
At the end of the year, cars made in the current year are marked down to make room for next year's models. One particular model has a sale price of $12,806, which is 24% less than it sold for when it was new. What was the original price of the vehicle?
9514 1404 393
Answer:
$16,850
Step-by-step explanation:
The sale price is 1 -24% = 76% of the original price (p). An equation is ...
12806 = 0.76p
12806/0.76 = p = 16850
The original price of the vehicle was $16,850.

Find the equation of a line parallel to the equation y = 5x + 7 through the point (2,7).
Answer:
y = 5x + 7
Step-by-step explanation:
1. Substitue the numbers into their spots.
7 = 5(2)+b
2. Find b by simplifying
7 = 10 + b
-3 = b
3. Substitute it back in since parallel lines have the same slope.

x
1 mm (width)
x
1 mm (height)
is 1 mm

Suppose that f(x) = 3 (8x - x^2)/256 for 0 < x < 8
Determine the following probabilities. Round all of your answers to 3 decimal places (e.g. 98.765).
a. P(X < 5)
b. P(X< 9)
c. P(5 < X < 7)
d. P(X > 3)
e. Determine x such that P(X < x) = 0.95
Answer and Step-by-step explanation: This function is a probability density function of a random variable X:
[tex]f(x)=\frac{3(8x-x^{2})}{256}[/tex]
and to calculate probabilities, we will have to integrate it:
[tex]P(X<x)=\int\limits^x_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]
Solving:
[tex]P(X<x)=\frac{3}{256}(4x^{2}-\frac{x^{3}}{3} )[/tex]
Then:
a. P(X < 5)
[tex]P(X<5)=\int\limits^5_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]
[tex]P(X<5)=\frac{3}{256}(100-\frac{125}{3} )[/tex]
[tex]P(X<5)=\frac{3}{256}(\frac{300-125}{3} )[/tex]
[tex]P(X<5)=\frac{175}{256}[/tex]
P(X < 5) = 0.683
b. P(X < 9)
Since density function's upper limit is 8, probability of x < 9 is 100% or 1.
So, P(X < 9) = 1
c. P(5 < X < 7)
[tex]P(5<X<7)=\int\limits^7_5 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]
[tex]P(5<X<7)=\frac{3}{256}[4(7)^{2}-\frac{7^{3}}{3}-4(5)^{2}+\frac{5^{3}}{3}][/tex]
[tex]P(5<X<7)=\frac{3}{256}[96-\frac{218}{3} ][/tex]
[tex]P(5<X<7)=\frac{70}{256}[/tex]
P(5 < X < 7) = 0.273
d. P(X > 3)
[tex]P(X>3)=\int\limits^8_3 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]
[tex]P(X>3)=\frac{3}{256}[256-\frac{512}{3}-36+9 ][/tex]
[tex]P(X>3)=\frac{3}{256}(229-\frac{512}{3} )[/tex]
[tex]P(X>3)=\frac{175}{256}[/tex]
P (X > 3) = 0.683
e. P(X < x) = 0.95
[tex]0.95=\int\limits^x_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]
[tex]\frac{3}{256}[\frac{12x^{2}-x^{3}}{3} ] =0.95[/tex]
[tex]\frac{12x^{2}-x^{3}}{256}=0.95[/tex]
[tex]12x^{2}-x^{3}=243.2[/tex]
[tex]-x^{3}+12x^{2}-243.2=0[/tex]
Solving this cubic equation, we have three values for x:
x₁ = -3.909
x₂ = 8.992
x₃ = 6.917
The value of x will the one between 0 and 8, which are the limits of the function. So, value of x which gives a probability of 0.95 is x = 6.917.
