The picture shows the number of colored shirts sold this week at Joan’s Clothing Shop. Joan assumes this trend will continue. She is going to put in an order for 500 colored shirts. How many of these should she order in orange?
Answers
Answer:
She should order 96 orange shirts
Step-by-step explanation:
The picture is shown below.
From the picture below Joan sold 10 blue shirts, 3 gray shirts , 5 orange shirts and 8 green shirts out of the colored Shirts. The ratio of the colored shirt sold are 10 : 3 : 5 : 8 . The total shirt sold that week is 10 + 3 + 5 + 8 = 26 colored shirts.
If she assumes the trend is going to continue the number of orange she should order can be calculated below.
Let us find the ratio of orange shirt sold to the total colored shirt sold.
orange shirt sold / total colored shirt sold = 5/26
This means every group of 26 colored shirts sold will have 5 orange shirt . So they told us she requested a total of 500 colored shirts . Following the same trend, how many group of 26 colored shirt are in 500.
5/26 = x/ 500
cross multiply
2500 = 26x
divide both sides by 26
x = 2500/26
x = 96.15
x = 96 orange shirts
She should order 96 orange shirts
Answer:
The answer would be B) 96 orange shirts is the answer

What is the first step to isolate the variable term on one side of the equation?
What is the second step to solve for x?
Answers
We have been given an equation [tex]gv=-3x +5[/tex]. We are asked to solve our given equation for x.
First of all, we will separate expression with x on one side of equation. We can do it by subtracting 5 from both sides of equation.
[tex]gv-5=-3x +5-5[/tex]
[tex]gv-5=-3x[/tex]
Now we will switch the sides as:
[tex]-3x=gv-5[/tex]
Now we will divide both sides by [tex]-3[/tex] as:
[tex]\frac{-3x}{-3}=\frac{gv-5}{-3}[/tex]
[tex]x=-\frac{gv-5}{3}[/tex]
Therefore, the value of x would be [tex]-\frac{gv-5}{3}[/tex].
Answer:
the first one is add 1/2x to both sides and for the second one is multiply both sides by 6/7

A device tests whether each light on a string of LED lights is functioning properly. A company estimates that 2.3% of LED lights that they produce are defective. The device is 96% accurate for lights that are functioning properly and 94% accurate for lights that are defective. You use the device to test a randomly selected light. What is the probability that the test result is correct? Round your answer to the nearest tenth.
Answers
Answer:
96% probability that the test result is correct
Step-by-step explanation:
We have these following probabilities:
2.3% probability that a randomly selected light is defective.
If the light is defective, 94% probability that the test result is correct.
100-2.3 = 97.7% probability that a randomly selected light is not defective.
If the light is not defective, 96% probability that the test result is correct.
What is the probability that the test result is correct?
94% of 2.3% and 96% of 97.7%. So
p = 0.94*0.023 + 0.96*0.977 = 0.96
96% probability that the test result is correct

Two boys decided to buy a computer. The second boy had 5/6 of the money the first had. The first boy had 7/8 of the price of the computer. Together they had $696 more than they need to pay. What is the price of the computer?
Answers
Answer:
The price of the computer is $1,152
Step-by-step explanation:
Let the price of the computer be $x
The first boy boy had 7/8 of this amount, the amount he has is thus 7/8 × $x = 7x/8
The second boy had 5/6 of what the first boy had. The amount of money he has is thus 5/6 × 7x/8 = 35x/48
Now, the addition of what they have is $696 more than what they need to pay. This amount is x+ 696
Mathematically, this can be represented as;
7x/8 + 35x/48 = x + 696
(42x + 35x)/48 = (x + 696)
77x/48 = (x + 696)
77x = 48(x + 696)
77x = 48x + 33408
77x - 48x = 33408
29x = 33, 408
x = 33,408/29
x = $1,152
In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. Find the length of IJ to the nearest tenth of a foot.
Answers
We have been given that in ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. We are asked to find the length of IJ to the nearest tenth of a foot.
First of all, we will draw a right triangle using our given information as shown in the attachment.
We can see that in triangle HIJ, the side IJ is adjacent side to angle I and JH is opposite side to angle I.
We know that tangent relates opposite side of right triangle to adjacent side.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(29^{\circ})=\frac{88}{IJ}[/tex]
[tex]IJ=\frac{88}{\text{tan}(29^{\circ})}[/tex]
[tex]IJ=\frac{88}{0.554309051453}[/tex]
[tex]IJ=158.7562024638191237[/tex]
Upon rounding to nearest tenth, we will get:
[tex]IJ\approx 158.8[/tex]
Therefore, the length of the side IJ is approximately 258.8 units.

A parks and recreational board in Birch County is interested in estimating the proportion of its residents in favor of having more public parks in that county. A random sample of Birch County residents was selected. All the selected residents were asked, "Are you in favor of having more public parks in your county?" A 98% confidence interval for the proportion of residents in favor of having more public parks in that county was calculated to be 0.54 ± 0.03. Which of the following statements is correct?
a. At the 98% confidence level, the majority of area residents is in favor of having more public parks in that county.
b. At the 98% confidence level, the estimate of 0.54 is within 0.03 of the true proportion of county residents in favor of having more public parks in that county.
c. In repeated sampling, 98% of sample proportions will fall in the interval (0.51, 0.57).
d. In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
e. In repeated sampling, 98% of the time the true proportion of county residents in favor of having more public parks in that county will be equal to 0.54.
Answers
Answer:
B.
Step-by-step explanation:
Trust me.
I just did it.
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
Option D is the correct answer.
What is a confidence interval?A confidence interval is a range of values that is likely to contain the true value of an unknown parameter, such as a population means or proportion, based on a sample of data from that population.
It is a statistical measure of the degree of uncertainty or precision associated with a statistical estimate.
We have,
The 98% confidence interval for the proportion of residents in favor of having more public parks in the county is 0.54 ± 0.03.
This means that we are 98% confident that the true proportion of residents in favor of having more public parks in the county falls within the interval from 0.51 to 0.57.
Now,
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
Option a is incorrect because we cannot determine whether the majority of residents are in favor of having more public parks based solely on the confidence interval.
Option b is incorrect because we cannot determine whether the estimate of 0.54 is within 0.03 of the true proportion of county residents in favor of having more public parks based solely on the confidence interval.
Option c is incorrect because it is a statement about the probability of the sample proportion falling within the interval in repeated sampling, which is not the same as the true proportion falling within the interval.
Option e is incorrect because it is a statement about the probability of the true proportion being equal to 0.54 in repeated sampling, which is not necessarily true based solely on the confidence interval.
Thus,
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).

Jack and Jill both ordered pizzas from Wayne’s pizza for their parties. Jack paid $58.50 for 3 pepperoni pizzas and 2 plain pizzas. Jill paid $67 for two pepperoni pizzas and 4 plain pizzas. How much does Wayne’s pizza charge for a plain pizza and for a pepperoni pizza ?
Answers
Answer:
A plain pizza is $10.50. A pepperoni pizza is $12.50.
Step-by-step explanation:
Solve a system of equations. Call x the price of plain pizzas and y the price of pepperoni pizzas. From the question we are told that for Jack:
[tex]58.50=2x+3y[/tex]
And for Jill:
[tex]67=4x+2y[/tex]
There are several ways to solve this. I'll used elimination. Multiply the first equation by 2:
[tex]117=4x+6y[/tex]
Now subtract the second equation from the first - this will get rid of the x, leaving only y, which can be solved for:
[tex](117-67)=(4x-4x)+(6y-2y)\\50=4y\\y=12.5[/tex]
Now sub the value for y into either of the original equations and solve for x. I'll use the first:
[tex]58.5=2x+3(12.5)\\58.5=2x+37.5\\21=2x\\x=10.5[/tex]
Answer:
One plain pizza would be $10.50 and one pepperoni pizza would be $12.50.

the floor hallaway in the building has an area of 280 square feet. the hallway is 8 feet wide. how many feet long is the hallway?
Answers
Final answer:
To find the length of the hallway, divide the area (280 square feet) by the width (8 feet), resulting in a hallway that is 35 feet long.
Explanation:
The student's question involves the calculation of the length of a hallway when given the area and the width. To solve for the length, we use the formula for the area of a rectangle, which is area = length imes width. Since the area of the hallway is 280 square feet and the width is 8 feet, we divide the area by the width to find the length:
Length = Area / Width
Length = 280 sq ft / 8 ft
Length = 35 feet
Therefore, the hallway is 35 feet long.
