Step by step explanation if you see the right angle at 57 degrees it part of x so x plus 57 is 90 and 90 minus 57 is 33 so x is 33 and x and y also form a right angle so x plus y should equal 90 and 90 minus 33 is 7 so that’s Y
Answer:
X=33 degrees
Y= 45
Step-by-step explanation:
The x would've been 90 degrees but the 57 degrees got in the way so if you subtract the 57 from 90 you get 33.
The y is if you look on the opposite side of the y there is a blank space that is the same exact size as the y size. So that would've been a 90 degrees as well but the other 90 degrees cut in the middle of it. Making you divide 90 in half.

21 boys
Step-by-step explanation:
2:3=14:x you cross multiply this to find the amount of boys
2x=42
x=21
There are 21 boys in the class.
Basically, solve what you have there with cross-multiplication.
2x = 14 x 3
2x = 42
Then divide both sides by 2. (edited it bc didn't say what you actually had to do)
2x ÷ 2 = 42 ÷ 2
x = 21.

Step-by-step explanation:
Answer:
I think the answer will be 225. Because 1st she got 100 for starting the job and 25 $ for per hour. She did 5 hours. So five times 25 . It will be 125 and 100 . The answer is 225
Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what percentage of IQ scores are at least 59? Please do not round your answer.
Answers
Answer:
1.35%
Step-by-step explanation:
Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what ? Please do not round your answer.
Empirical rule formula states that:
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .
We don't know the number of Standard deviation yet , hence:
Mean = 104
Standard deviation = 15.
At least 59
Hence:
104 - 15x = 59
104 - 59 = 15x
45 = 15x
x = 45/15
x = 3
Hence, At least 59 is 3 standard deviations away from the mean on one side of the distribution thus,
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .
100% - 99.7%
= 0.003
Since it is on one side of the distribution:
= 1.5% - 0.3%
= 0.015 - 0.0015
= 0.00135
Converting to percentage
= 1.35%
The percentage of IQ scores that are at least 59 is 1.35%
Suppose a researcher wants to make sure that the probability of committing a Type I error is less than 5%. How can the researcher control for this?A. Set the value for a Type II error at 0.05.
B. Set the alpha level at 0.05.
C. Place the rejection region in both tails.
D. Both setting the alpha level at 0.05 and placing the rejection region in both tails.
Answers
Answer:
B. Set the alpha level at 0.05.
Step-by-step explanation:
Hypothesis testing is a procedure whereby a researcher determines if the null hypothesis is rejected or accepted, depending on the significant level or the alpha level. When a type I error is made, the null hypothesis is rejected even though it is correct. To solve this problem, the significant or alpha level is set to 5% or 0.05.

Step-by-step explanation:
The cost to manufacture a product is proportional to the quantity produced, with a cost of $35000 dollars per day when 700 items are produced. The cost to store n items is proportional to the square of n, with a daily storage cost of $3430 dollars when 700 items are stored. In addition, there is a fixed daily cost of $7000. The total daily cost, T when producing and storing n items is the sum of production, storage and fixed costs.
Write a formula for T as a function of n.
Answers
Solution :
[tex]$T_1$[/tex] = k.n (cost proportional to quantity)
35000 = k . 700
k = [tex]$\frac{35000}{700}$[/tex]
= 50
So [tex]$T_1$[/tex] = 50 n
Now [tex]$T_2=Pn^2$[/tex] (cost proportional to square of n)
[tex]$3430= P(700)^2$[/tex]
3430 = 490000 P
[tex]$P = \frac{3430}{490000}$[/tex]
[tex]$P = \frac{7}{1000}$[/tex]
[tex]$T_2=\frac{7}{1000}n^2$[/tex]
Now, [tex]$T_3= 7000$[/tex] (fixed)
Therefore,
Total, [tex]$T=T_1+T_2+T_3$[/tex]
[tex]$T=50n+\frac{7}{1000}n^2+7000$[/tex]
[tex]$T=0.007n^2+50n+7000$[/tex]
The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.
Given that ,
The total daily cost = T
When producing and storing n items is the sum of production, storage and fixed costs.
The manufacturing cost of a product when 700 items produced = $35000 dollars per day.
Daily storage cost of when 700 items are stored = $3430 dollars
We have write the formula in terms of total daily cost T and n stored items.
According to the question,
The cost to manufacture a product is proportional to the quantity produced, with a cost of $35000 dollars per day when 700 items are produced.
Where ,total daily cost T and n stored items.
[tex]T_1 = k . n[/tex]
$35000 = k.700
[tex]k = \frac{35000}{700}[/tex]
k = $50
The cost to store n items is proportional to the square of n, with a daily storage cost of $3430 dollars when 700 items are stored.
[tex]T_2 = pn^{2}[/tex]
$3430 = P [tex](700)^{2}[/tex]
$3430 = P 490000
[tex]P = \frac{3430}{490000} \\\\P = \frac{7}{1000}[/tex]
There is a fixed daily cost of $7000.
[tex]T_3 = 7000[/tex]
Combine all the equation ,
Where T = [tex]T_1 = T_2 = T_3[/tex] and p = k =n
T = 0.000[tex]n^{2}[/tex] + 50 n +7000
Hence, The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.
