Answer:
c = 36.06
Step-by-step explanation:
a² + b² = c²
20² + 30² = c²
400 + 900 = c²
c² = 1300
[tex]\sqrt{c^2} =\sqrt{1300}[/tex]

What is 5/4 minus 1/3?
Answer:
11/12
Step-by-step explanation:
5/4 ---- 15/12
1/3------ 4/12
11/12
Answer:
11/12
Step-by-step explanation:
Hello! The answer to this question is 11/12. In this case, we want to make the denominator the same. To make the denominator the same we need to find the lowest common multiple. In this case the lowest common multiple is 12, (because 12 is the smallest number that 3 and 4 are both factors for.) 4x3=12 so now the denominator in 5/4 is 12 but whatever we do the bottom we do to the top. So since we multiplied the bottom (denominator) by 3 we have to multiply the top (numerator) by 3 as well. 5x3=15. Therefore, we now changed 5/4 to 15/12. Now, we have to do the same to the 1/3. 3x4= 12. 1x4=4. Now we have the two numbers, 15/12 and 4/12. 15/12-4/12=11/12! Therefore, your answer is 11/12. Hope this explanation helps! Happy learning!

g Company A and Company B both produce a part used in a 3D Printer. A random sample of 9 parts from Company A results in a sample mean equal to 128.2 ft-lbs and a sample standard deviation 17.8 ft-lbs. A random sample of 8 parts from Company B gives a sample mean equal to 138.4 ft-lbs and a sample standard deviation 14.9 ft-lbs. If you do a test of hypothesis to see if the population variances of Company A and Company B parts are equal or not, what is the numerical value of the test statistic
Answer:
The value of test statistic is F = 1.427
Step-by-step explanation:
The given data is
n1=9; s1=17.8
n2=8 s2=14.9
1) And significance level is chosen to be α = 0.05.
2) The null and alternate hypothesis are
H0: σ₁²=σ₂² against the claim Ha: σ₁²≠σ₂²
The null hypothesis the population variances of Company A and Company B parts are equal.
against the claim
the population variances are not equal of the two companies.
3) The critical region F∝(υ1,υ2) = F(0.025)8,7 > 4.9
where υ1= n1-1= 9-1= 8 and υ2= n2-1= 8-1= 7
4)Test Statistic
F = s₁²/s₂²
F= 17.8²/ 14.9²= 1.427
5) Conclusion :
As the calculated F lies in the acceptance region therefore we conclude that there is not sufficient evidence to support the claim that the population variances of Company A and Company B parts are not equal. Hence Ha is rejected and H0 is accepted.
Convert the angle 2π/3 radians to degrees.
Answer:
2π/3 radians is equal to 120°.
Step-by-step explanation:
In this problem, we need to convert the angle 2π/3 radians to degrees.
The relation radian and degree is given by :
[tex]D=\dfrac{180}{\pi}\times R[/tex]
Substitute all the values,
[tex]D=\dfrac{180}{\pi}\times \dfrac{2\pi }{3}\\\\D=120^{\circ}[/tex]
So, 2π/3 radians is equal to 120°.

write the log equation as an exponential equation
Given:
The equation is:
[tex]\log_{(x-2)}(x^2-4x-6)=\dfrac{4}{5}[/tex]
To find:
The exponential equation of the given logarithmic equation.
Solution:
We have,
[tex]\log_{(x-2)}(x^2-4x-6)=\dfrac{4}{5}[/tex]
According to property of logarithm,
[tex]\log_ax=b\Leftrightarrow x=a^b[/tex]
Using the property of logarithm, we get
[tex]x^2-4x-6=(x-2)^{\frac{4}{5}}[/tex]
Therefore, the required exponential equation is [tex]x^2-4x-6=(x-2)^{\frac{4}{5}}[/tex].
The radius of the cylindrical construction pipe is 2.5ft, if the pipe is 25ft long, what is the volume? Use the value 3.14 for pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer
Answer:
Step-by-step explanation:
r = 2.5 ft
h = 25 ft
Volume of cylindrical pipe = πr²h
= 3.14 * 2.5* 2.5 * 25
= 490.625 {as tenth place value is ≥ 5, add 1 to the whole number}
= 491 cubic feet
According to the Insurance Institute for Highway Safety, the national rate for 16-year-old males was 210 accidents for every 1000 drivers (21%) during the year 2000. In a large city in the Midwest, a random sample of 150 16-year-old male drivers found that 25 of them had been in an accident during the year 2000. Does this city have a lower proportion of accidents by 16-year-old male drivers than the national proportion?
Answer:
Yes. The city has a lower proportion of accidents by 16-year-old male drivers than the national proportion (16.7% compared to 21%).
Step-by-step explanation:
a) Data and Calculations:
Number of 16-year-old males involved in driver accident during year 2000 = 210
Sample number of drivers = 1,000
National rate of accidents for 16-year-old males for every 1,000 drivers = 21% (210/1,000 * 100)
Random sample of 16-year-old male drivers in a Midwest city = 150
Number of them involved in driver-accidents = 25
Proportion of 16-year-old males involved in driver-accidents = 25/150 * 100 = 16.7%
The city's 16.7% proportion is lower than the national proportion of 21%.

A- 10
B- 8
C- 6
D- 2
Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2

4) If the area of a triangle is
72 square feet and the base is 12 feet, what is the height?
Help ASAP
Answer:
The height is 12 feet.
Step-by-step explanation:
The formula for area of a triangle is 1/2 ⋅ b (base) ⋅ h (height).
Now let's plug in the numbers.
According to the word problem, the base is 12 feet.
As of now, our equation is: 1/2 ⋅ 12 ⋅ h
The only number times 1/2 that would give you an answer of 72 is 144.
12⋅12 = 144.
This means the height is 12.
And, 1/2 ⋅ 12 ⋅ 12 ⋅ = 72.
Because the area of the triangle is 72, 72 is the number we are looking for.
Therefore, the height is 12.
I really hope this made sense, it was a bit rushed.
Wells Fargo has realized that they lose home mortgage business to other banks that can process the loan applications with less variability in the time it takes to process each application. The bank recently studied this problem, and found that the processing time T is normally distributed with a mean of 13 days. They didnt measure the standard deviation, but they know that 50% of all applications were processed in between 10.5 and 15.5 days. After learning all this, they then fired half of their mortgage loan officers and replaced them with new recruits. They then sampled 25 applications, and found a sample mean of 13 days (same as the old) and a sample standard deviation of 2.5 days.
(a) Test whether their actions have significantly changed their processing time T.
(b) Based on the sample of 25 applications, give a 90% confidence interval for the parameter that
has changed.
