Sarah is doing research on the average age of first-year resident physicians. She wants her estimate to be accurate to within 1 year. From past studies, she knows the population standard deviation is 8.265. How many first-year residents must she survey to be 95% confident?
Answers
Answer: The number of first-year residents she must survey to be 95% confident= 263
Step-by-step explanation:
When population standard deviation ([tex]\sigma[/tex]) is known and margin of error(E) is given, then the minimum sample size (n) is given by :-
[tex]n=(\dfrac{z^*\sigma}{E})^2[/tex], z* = Two-tailed critical value for the given confidence interval.
For 95% confidence level , z* = 1.96
As, [tex]\sigma[/tex] = 8.265, E = 1
So, [tex]n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}][/tex]
Hence, the number of first-year residents she must survey to be 95% confident= 263
A juice shop uses 1/2 of a bag of oranges to make 5 glasses of orange juice. What fraction of a bag of oranges did the shop use to make one glass?
Answers
Answer: 0.1 OR 1/10
Step-by-step explanation:
Think about it: There's 1/2 bag of oranges, and you wanna know what number of oranges used in the juice. Take 1/2, and divided it by 5. You get 0.1, then you should turn it into a fraction, giving you 1/10.

Leyla needs to hire a plumber to fix a few things around her house. She will need plumbing service for a total of 3 hours. Which plumbing service should she go with to save money? How much will she save? Justify your answer.
Answers
Great! So let’s solve for Joe’s Plumbing charges first. To find his price for 3 hours, solve J(3)=45(3)=$135.
Now let’s find Mark’s Plumbing charges. To find his price for 3 hours, plug 3 into M(t)=40t+25. So, M(3)=40(3)+25=$145.
Therefore, Joe’s Plumbing is cheaper than Matt’s plumbing by 10 dollars for a 3 hour job.

Don claims that perpendicular lines are lines that intersect such that at least one of the angles is a right angle.
Determine whether each statement below justifies the claim. Select Yes or No for each statement.
Yes No
Intersecting lines allow for the creation of four angles with a common vertex.

If one of the angles is a right angle, the angle vertical to it must also be a right angle.
Because linear pairs are complementary, the remaining two angles must also be right angles. O

If there are 4 ships at a port and the first one leaves and comes back every three weeks, the second one every nine weeks, the third one every 12 weeks, and the fourth every 24 weeks when will they all be in the port at the same time/when will they be there all at the same week
Answers
Answer: After 72 weeks they will be in the port at the same time.
Step-by-step explanation:
Given, Total ships = 4
The first one leaves and comes back every 3 weeks, the second one every 9 weeks, the third one every 12 weeks, and the fourth every 24 weeks .
So, the number of weeks they will take to be in the port at the same time = L.C.M. (3, 9, 12 , 24) (L.C.M. = least common multiple)
Since, 9= 3 x 3
12 = 2 x2 x 3
24 = 2 x 2x 2 x3
then, L.C.M. (3, 9, 12 , 24)= 2 x 2x 2 x 3 x3 =72
Hence after 72 weeks they will be in the port at the same time.

In the diagram below, find the value of y.
Answers
Answer:

Step-by-step explanation:
1) combine all like terms for the inside angles of the triangle
(3x-19) + (4x+8) + (x+7)3x-19+4x+8+x+78x-42) because the sum of all angles = 180 add that to the sum of all like terms
8x-4=180add 4 on both sides and divide both sides by 8this should be x=233) now you replace the x's with 23
(3(23) -19)69-19504) now we know that (3x-19)=50
5) take 180 and subtract 50
this is because y and (3x-19) creates a supplementary angle which also equals 1806) 180-50=130
3/4(x+8) > 1/2(2x+10)
