Step-by-step explanation:
A new test is developed to test for a certain allergy, giving "positive" or "negative" results to indicate that a person does or does not have the allergy. For a person who has the allergy, the test will give a positive result 82% of the time and a negative result (false negative) 18% of the time. For a person who does not have the allergy, the test will give a positive result (false positive) 10% of the time and a negative result 90% of the time. A study included a population of 10,000 people, and 1% of those studied where known to have the allergy. Fill in the missing values in the table below, and complete the statements that follow. Round the percentage to the nearest tenth, if necessary.
Answer:
the first blank is 82, the second blank is 8,910. I got that third blank wrong and it should be 7.1 I think. and the last block is should not. to find the third box all you need to do is:82+990=1,072 then divide 82 by 1,072 and round to the nearest tenthAnswer:

Step-by-step explanation:
Hope this helps <3
Answer:
=1/6
Step-by-step explanation:
First of all you have to find the lcm of the two denominators which are, 3 and 2
Lcm of 2 and 3 =6
Then divide 6 by by the denominators and multiply by numerators, which gives you
(4-3) / 6
After solving the above, we then arrive at 1/6 as our answer.

what is the surface area of the cylinder with height 8 ft and radius 3 ft round your answer to the nearest thousand.
Answer:
207.24
Step-by-step explanation:
[tex]S_{surface} = S_{side} + 2*S_{base} \\S_{side} = 2\pi RH\\ = 2*3.14*3*8=150.72\\S_{base} = \pi R^{2} = 3.14 * 3^{2} = 28.26\\S_{surface} = 150.72 + 2* 28.26 = 207.24[/tex]

Jordan wants to split up his socks and shoes into groups. If he has 6 pairs of shoes and 14 pairs of socks, how many groups must he create so he has an equal number of pairs of shoes and pairs of socks?
Answer:
i amm not sure
Step-by-step explanation:
The number of groups Jordan must create so he has an equal number of pairs of shoes and pairs of socks is 2.
What is HCF?The highest common factor (HCF) is discovered by identifying all common factors of two integers and then picking the greatest one. For example, the common factors of 8 and 12 are 1, 2, and 4. The greatest common factor is four.
Jordan wants to split up his socks and shoes into groups. If he has 6 pairs of shoes and 14 pairs of socks. Therefore, she can divide the pair of socks and shoes only into groups of 2, because two is the HCF of 6 and 14.
Hence, the number of groups Jordan must create so he has an equal number of pairs of shoes and pairs of socks is 2.

Nadia compares the weights, in grams, of some apples and oranges she find the median abs interquartile range of the weights.
Answer:
Apple
Orange
Step-by-step explanation:
Apple has the greater median with a median value of 150 which is more than that of orange at 130
The sample with the greater variability is the orange sample as the interquartile range value of 11 is greater Than 8 for Apple.
Yes it is possible, because of the greater variation on weight shown by the sample of oranges, then it could be possible.
A study by the department of education of a certain state was trying to determine the
mean SAT scores of the graduating high school seniors. The study found that the
mean SAT score was 447 with a margin of error of 21. Write a confidence interval for
the true mean SAT score of the graduating high school seniors.
Answer:
(426 ; 468)
Step-by-step explanation:
Confidence interval :
Mean score ± margin of error
Margin of Error = 21
Mean SAT score = 447
Hence,
447 ± 21
Lower boundary = 447 - 21 = 426
Upper boundary = 447 + 21 = 468

The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
60 ft long bc that would leave 10ft on each side of the banner...Step-by-step explanation:
Hopes this helps. Mark as brainlest plz!Answer:
Solution given:
length [l]=breadth [b]=40ft
Now
length of concession banner[h]=?
we have
perpendicular [p]=base[B]=40ft
by using Pythagoras law
h²=p²+b²
h²=40²+40²
h=√3200
h=40√2
So
the length of the concession stand to determine if the school banner can fit across the length of the concession stand is 40√2 ft or 56.57ft

Suppose that among all U.S. Students, 80% have gone to an amusement park and 45% have gone to a beach. Only 15% have done neither. If you select a student at random, what is the probability that the student has gone to the beach but not to an amusement park
Answer:
5%
Step-by-step explanation:
Let x represent the percentage of people that have gone to both the park and the beach.
The percentage of people that have gone only to the amusement park = 80% - x% = 80 - x
The percentage of people that have gone only to the beach = 45% - x% = 45 - x
Therefore:
100% = (80 - x) + (45 - x) + (x) + (15)
100 = 80 + 45 + 15 -x - x + x
100 = 140 - x
x = 140 - 100
x = 40%
Therefore 40% of the students have gone to both the park and the beach.
The probability that the student has gone to the beach but not to an amusement park = 45% - 40% = 5%

Answer:
Choice B: Only (-1,-5)
Step-by-step explanation:
With this one, first the equation needs to be reduced into point-slope format.
y+5=2(x+1)
Distributive Prop.
y+5=2x+2
Carry over the 5 to the opposite side.
y=2x-3
Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.
Choice A: X is 5; Y is 10
y=2x-3
y=2(5)-3
y=10-3
y=7
This does not give a y value of 10, so it is false.
Choice B: X is -1; Y is -5
y=2(x)-3
y=2(-1)-3
y= -2-3
y= -5
This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.

Which graph represents the equation y = x2-5?
Clay surveys members of his class to find out how many televisions they have in their homes. The thirteen responses he received are shown in the table. Which statement is true?
A) The mean is less than the mode.
B) The mean is less than the range.
C) The mean is greater than the range.
D) The median is greater than the mode.
Answer:
B, the mean is less than the range
Step-by-step explanation:
mean is 3.38 (rounded)
mode is 3
median is 3
range is 5
The mean is 3.38 and the range is 5, So the mean is less than the range. Option B is the correct one.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Mean = [tex]\frac{1+5+2+3+4+6+3+1+3+4+3+5+4}{13}[/tex]
The mean is 3.38 (rounded)
Median represents the middle value of the given data when arranged in a particular order.
So, the Median would be 3.
Mode is that number that appears most frequently in the given set of data.
So, the Mode would be 3.
The range of a given set of data is the difference between the largest value and the smallest value.
So, the range would be 5
