1 and 1/2
Step-by-step explanation:
Which of the following is correct? Multiple Choice When the sample size increases, both α and β may decrease. Type II error can only occur when you reject H0. Type I error can only occur if you fail to reject H0. The level of significance is the probability of Type II error.
Answer:
(A) When the sample size increases, both α and β may decrease.
Step-by-step explanation:
Which of the following is correct?
(A) This option is right.
When a sample's size increases, the values for alpha and beta may decrease; if and only if sample size is the denominator in the slope equation (in each case) and the numerator stays the same (that is, ceteris paribus; all other things being equal). The larger the denominator, the smaller the slope value for alpha and beta.
(B) This option is wrong
Type 2 error can only occur when you fail to reject a true H0
(C) This option is wrong
Type 1 error can only occur if or when you don't reject a false H0
(D) This option is wrong
The level of significance is the probability of a Type 1 error, not the probability of a Type 2 error.

Answer:
divide 25.5 by 6
or change them to fractions
51/2 divided by 6 = 51/2 x 1/6 = 51/12 = 4 3/12 = 4 1/2 feet each
Step-by-step explanation:
Answer:
He will have 10 shorter pieces
To find this, divide 12.5 from 1.25

A 2-column table with 5 rows titled Length Conversion. Column 1 is labeled Inches, x with entries 2, 4, 7, 10, 13. Column 2 is labeled Centimeters, y with entries 5.08, 10.16, 17.78, 25.4, 33.02. What is the range of the relation of centimeters as a function of inches? {5.08, 10.16, 17.78, 25.4, 33.02} all positive integers x greater-than-or-equal-to 0 y greater-than-or-equal-to 0
Answer:
d
Step-by-step explanation:
The range of the relation of centimeters as a function of inches y ≥0.
What is Range of Function?A function's range includes all conceivable values for y. Y = f(x) is the formula to determine a function's range. It is only a function in a relation if each x value has exactly one y value.
Given:
Column 1 Column 2
2 5.08
4 10.16
7 17.78
10 25.4
13 33.02
As, we know the range is the output values.
So, range is {5.08, 10.16, 17.78, 25.4, 33.02}
Thus, the range is ≥ 0.
Hence, the range of the y ≥0.

Calculate the acceleration of gravity on the surface of Mars
Express your answer with the appropriate units.
Given :
Los Angeles and Las Vegas.
Mass of Mars , [tex]M=6.42\times 10^{23}\ kg[/tex].
Radius of Mars ,
[tex]R=3397\ km\\\\R = 3.397\times 10^6\ m[/tex]
To Find :
The acceleration of gravity on the surface of Mars.
Solution :
Acceleration due to gravity is given by :
[tex]g_m = \dfrac{GM_m}{R_m^2}\\\\g_m =\dfrac{(6.67\times 10 ^{-11}\ m^3\ kg^{-1}\ s^{-2})(6.42\times 10^{23}\ kg) }{(3.397\times 10^6\ m)^2}\\\\g_m = 3.71\ m/s^2[/tex]
Therefore, the acceleration of gravity on the surface of Mars is 3.71 m/s².
Hence, this is the required solution.
Steven Starr has an idea for a desert he is preparing to sell via food truck for restaurant week- grilled bananas with Belgian chocolate ganache. The bananas go through a 4-step process consisting of pealing, filling, grilling, and the last 2 steps are performed simultaneously- splashing and wrapping. Pealing takes 1 minute, filling takes 2 minutes and grilling takes 5 minutes. Splashing takes 3 minute and wrapping takes 3 minutes. a. The bottleneck of the process is _____, with an hourly capacity of _____.
Answer:
a) grilling
b) 12 grilling process per hour
Step-by-step explanation:
the bottleneck in this process is grilling, which slows down production by taking a considerable amount of time.
Grilling takes 5 minutes, which is the longest of any other stage of process
In one hour there are 60 minutes
The hourly rate of grilling is therefore 60/5 = 12 grilling process per hour

In one region, the September energy consumption levels for single-family homes are normally distributed with a mean of 1050 kWh and a standard deviation of 218 kWh. For a randomly selected home, find the probability that the September energy consumption level is between 1100 kWh and 1225 kWh.
a. 0.1971
b. 0.3791
c. 0.2881
d. 0.0910
e. 0.8029
Answer:
a. 0.1971
Step-by-step explanation:
Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]
Given that:
μ = 1050 kWh, σ = 218 kWh
For x = 1100 kWh
[tex]z=\frac{x-\mu}{\sigma}=\frac{1100-1050}{218} =0.23[/tex]
For x = 1225 kWh
[tex]z=\frac{x-\mu}{\sigma}=\frac{1225-1050}{218} =0.80[/tex]
From the normal distribution table, P(1100 < x < 1225) = P(0.23 < z < 0.8) = P(z < 0.8) - P(z < 0.23) = 0.7881 - 0.5910 = 0.1971

solve for b
A=h(a+b)2
Answer:
B = (A/(2h)) - a
Step-by-step explanation:
A = h(a+b)2
divide both sides of the equation by 2h
A/(2h) = a+b
subtract a from both sides
(A/(2h)) -a = b
Class Scheduling Enormous State University's Math Department offers two courses: Finite Math and Applied Calculus. Each section of Finite Math has 80 students, and each section of Applied Calculus has 70 students. The department will offer a total of 150 sections in a semester, and 11,200 students would like to take a math course. How many sections of each course should the department offer in order to fill all sections and accommodate all of the students
Answer:
70 section of Finite math and 80 section of Applied calculus
Step-by-step explanation:
As in each section, finite math has 80 student and applied calculus has 70 students
80x + 70Y = 11,200................(i)
There are 150 sections in a semester
x + y = 150..................................(ii)
Multiply equation (ii) by -70
-70x - 70y = 10,500
Add equation (i) and equation (iii)
80x + 70Y = 11,200
-70x - 70y = 10,500
10x = 700
x = 700/100
x= 70
Substitute x in equation (ii)
x + y = 150
70 + y = 150
y = 150 - 70
y = 80
Hence, 70 section of finite math and 80 section of applied calculus should the department offer in order to fill all sections and accommodate all of the students.

What percent of the circle is shaded?
Can you also explain to me please?
Answer:
75%
Step-by-step explanation:
Look at it this way since there is 8 what u could do is 1/4 so 2 of them are 25% 4 of them are 50% 6 of them are 75% and all 8 are 100%
Answer:
75%
Step-by-step explanation:
The circle is divided into 8 parts and 6 of those are shaded.
so as a fraction it would be 6/8
simplified it would be 3/4
percent is out of 100 so you have to make the denominator as 100
25 x 4 (the denominator of 3/4) is 100
25 x 3 ( the numerator of 3/4) is 75 you have to multiply both the numerator and denominator by the same number.
now you have 75/100
which is 75 percent

Molly took part in a math quiz and scored 55 points on 30 questions. Of the questions, there were 3-point word problems, 2-point calculation questions, and 1-point multiple-choice questions. She answered 5 more 2-point questions than 1-point questions correctly. Find how many of each type of question she answered correctly.
Answer:
[tex]3\ point\ word = 5[/tex]
[tex]2\ point\ word = 15[/tex]
[tex]1\ point\ word = 10[/tex]
Step-by-step explanation:
Given
Represent
3-point word with T;
2-point with U and
1-point with V
[tex]U = 5 + V[/tex] --- (1)
If total questions is 30, then
[tex]T + U + V = 30[/tex] --- (2)
If total points is 55, then
[tex]3T + 2U + V = 55[/tex] --- (3)
Substitute 5 + V for U in (2) and (3)
[tex]T + U + V = 30[/tex] --- (2)
[tex]T + 5 + V + V = 30[/tex]
[tex]T + 5 + 2V = 30[/tex]
[tex]T + 2V = 25[/tex] ---- (4)
[tex]3T + 2U + V = 55[/tex] --- (3)
[tex]3T + 2(5 + V) + V = 55[/tex]
[tex]3T + 10 + 2V + V = 55[/tex]
[tex]3T + 10 + 3V = 55[/tex]
[tex]3T + 3V = 55 - 10[/tex]
[tex]3T + 3V = 45[/tex]
Divide through by 3
[tex]T + V = 15[/tex] ---- (5)
Subtract (5) from (4)
[tex](T + 2V = 25 )- (T + V = 15)[/tex]
[tex]T - T + 2V - V = 25 - 15[/tex]
[tex]V = 10[/tex]
Recall that:
[tex]U = 5 + V[/tex]
[tex]U = 5 + 10[/tex]
[tex]U = 15[/tex]
Substitute 10 for V in (5)
[tex]T + V = 15[/tex]
[tex]T + 10 = 15[/tex]
[tex]T = 5[/tex]
Explain your steps to solve 3x +4/+2 = 29.
Answer:
X=18
Step-by-step explanation:
3x+4/2 = 29
Multiply both sides by 2 :
2(3x+4)/2 = 29*2
Simplify :
3x+4= 58
Subtract 4 from both sides :
3x + 4 - 4 = 58 - 4
Simplify :
3x = 54
Divide both sides by 3:
3x / 3 = 54 /3
Simplify :
X = 18
