Jiyoung spent $82 at Uniqlo on shirts and shorts. She lost the receipt but knows that the shirts are
$11 each, and the shorts were $9 each. If Jiyoung bought 5 shirts, how many shorts did she buy?
its 3 shorts
Step-by-step explanation:
11×5= 55 82-55= 27 27÷9= 3
Answer:
Step-by-step explanation:
Given this information, we can set up an equation
[tex]11x + 9y = 82[/tex], where x is the amount of shirts bought, and y is the amount of shorts bought. Since we know she bough 5 shirts, we can replace x with 5
[tex]11 (5) + 9y = 82[/tex] Now, we have to find for y.
Step 1. Simplify
[tex]55+9y=82[/tex]
Step 2. Subtract 55 from both sides
[tex]55-55+9y=82-55\\9y=27[/tex]
Step 3. Divide both sides by 9
[tex]\frac{9y}{9}=\frac{27}{9}\\y=3[/tex]
If y = 3, this means that Jiyoung bought 3 shorts.

b. If Aaron tunes into this station at 5 randomly selected times, will there be exactly one time when a commercial is playing?
Answer:
Yes, there will be with a probability of 0.4096
Step-by-step explanation:
Given,
p = 0.2
1 - p = 0.8
Number of trials, n = 5
P(x = 1)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 1) = 5C1 * 0.2^1 * 0.8^4
P(x = 1) = 5 * 0.2^1 * 0.8^4
P(x = 1) = 0.4096
Yes, there will be with a probability of 0.4096
Answer:
No. If Aaron tunes into this station at 5 randomly selected times, there will not necessarily be exactly one time when a commercial is playing.

Find the unknown angle measure by solving for the given variable.
Supplementary angles
Step-by-step explanation:
Given that,
∠PSQ = 13x+7
∠QSR = 42x+8
We need to find the measure of angles.
We can use the property of linear pair. ATQ,
13x+7 + 42x+8 = 180 (Linear pair)
Taking like terms,
13x+42x = 180 - 7-8
55x = 165
x = 3
So,
∠PSQ = 13x+7 = 13(3) + 7 = 46°
∠QSR = 42x+8 = 42(3) + 8 = 134°
Hence, this is the required solution.

write the edge of the cube in terms of its volume
Answer:
Step-by-step explanation:
The formula for the volume is given by
(side)3=volume
Since we have the volume, we must take the cube root of the volume to find the length of any one side (since it is a cube, all of the sides are equal).
(side)3−−−−−−√3=side=volume−−−−−−√3
Plugging in 216 for the volume, we end up with
side=6 cm
Answer:
a = ∛v
Step-by-step explanation:
Edge (a) volume (v)
v = a³
a = ∛v
-4 x f (8) + 3 x g(-7) HELP ASAP
Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32
Consider function f. f(x) = sqrt 7x- 21
Place the steps for finding f^-1(x) in the correct order.
please help:)
Answer:
f^-1(x) = (x² + 21)/7
Step-by-step explanation:
Since f(x) = y = √(7x – 21), to find the inverse of f(x) we have to write x in terms of y in order to make x the dependent variable and y the independent variable. The steps involved are:
Step 1: square both sides of the equation, y = √(7x – 21). Doing that, we have:
y² = 7x – 21
Step 2: Add 21 to both sides of the resulting equation. Doing that, we have:
y² + 21 = 7x
Step 3: Divide both sides of the equation by 7. Doing that we have:
x = (y² + 21)/7
Step 4: Replace x with f^-1(x) and y with x. Doing that, we have:
f^-1(x) = (x² + 21)/7

The chair of the operations management department at Quality University wants to construct a p-chart for determining whether the four faculty teaching the basic P/OM course are in control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results Instructor Number of Failures Prof. A 13 Prof. B 0 Prof. C 11 Prof. D 16 What are the .95 (5 percent risk of Type I error) upper and lower control limits for the p-chart
Answer:
Prof B and Prof D
Step-by-step explanation:
Step-by-step explanation:
From the question we are told that
Sample size 100
Instructor Number of Failures
Prof. A 13
Prof. B 0
Prof. C 11
Prof. D 16
Confidence level= 0.95
From Z table
Z=1.96
Generally proportion for failure is mathematically given as
[tex]Proportion\ of\ Failure\ P=\frac{Number\ of\ Failure\ N}{Sample\ size\ S}[/tex]
[tex]P=\frac{N}{S}[/tex]
For Prof A
[tex]P_A=\frac{N_A}{S}[/tex]
[tex]P_A=\frac{13}{100}[/tex]
[tex]P_A=0.13[/tex]
For Prof B
[tex]P_B=\frac{N_B}{S}[/tex]
[tex]P_B=\frac{0}{100}[/tex]
[tex]P_B=0[/tex]
For Prof C
[tex]P_C=\frac{N_C}{S}[/tex]
[tex]P_C=\frac{11}{100}[/tex]
[tex]P_C=0.11[/tex]
For Prof D
[tex]P_D=\frac{N_D}{S}[/tex]
[tex]P_D=\frac{16}{100}[/tex]
[tex]P_D=0.16[/tex]
Generally the average proportional failure is mathematically given as
[tex]P_a_v_g=\frac{0.13+0+0.11+0.16}{4}[/tex]
[tex]P_a_v_g=0.10[/tex]
Therefore having this we calculate for the control limits
Generally the upper control limit UCl is mathematically given as
Upper control limits:
[tex]UCL =P_a_v_g +Z\sqrt{\frac{P_a_v_g(1-P_a_v_g) }{S} }[/tex]
[tex]UCL =0.1 +1.96\sqrt{\frac{0.1(1-0.1) }{100}}[/tex]
[tex]UCL =0.1 +1.96*0.03[/tex]
[tex]UCL =0.1 +0.0588[/tex]
[tex]UCL =0.1588[/tex]
Generally the upper control limit UCl is mathematically given as
Lower limit control limits:
[tex]UCL =P_a_v_g _Z\sqrt{\frac{P_a_v_g(1-P_a_v_g) }{S} }[/tex]
[tex]UCL =0.1 -1.96\sqrt{\frac{0.1(1-0.1) }{100}}[/tex]
[tex]UCL =0.1 -1.96*0.03[/tex]
[tex]UCL =0.1 -0.0588[/tex]
[tex]UCL =0.0412[/tex]
Therefore the Range is 0.0412 to 0.1588
Given the range 0.0412 to 0.1588 Prof B and Prof D are outside the Range making them the correct options

Answer:
AE = 3
Step-by-step explanation:
First of all, we need to find corresponding sides that are defined in both figures. The table below shows the given values.
From the table, we can write the proportion ...
EA/RS = BC/TU . . . corresponding sides are proportional
EA/6 = 4/8 . . . . . . . substitute given lengths
EA = 6(4/8) = 3
The length of AE is 3 units.
