Find the critical value zα/2 that corresponds to a 83% confidence level
The critical value zα/2 that corresponds to a 83% confidence level is 1.37.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that the confidence level (C) = 83% = 0.83
α = 1 - C = 0.17
α/2 = 0.17/2 = 0.085
The z score of α/2 corresponds with the z score of 0.415 (0.5 - 0.085) which is equal to 1.37

Is 3/7 and 10/21 proportional ? 15 points
Answer:
NOT proportional.
Step-by-step explanation:
Get a common denominator of 21 by multiplying 7 and 3 by 3.
[tex]\frac{3}{7}(\frac{3}{3})=\frac{9}{21}[/tex]
When both fractions have the same denominator, their numerators are different. Therefore, they are NOT proportional.
Does anyone know what 1.2 divided by 0.4 is?
Answer:
it's 3. how could u not know that 0.4 x 3 = 1.2 duh
The value of the expression is 3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
1.2 ÷ 0.4
= 1.2 / 0.4
The decimal point gets canceled.
= 12/4
= 3
Thus,
The value of the expression is 3.

She thought the multiplication symbol was the addition symbol
actual answer: 1.39 x 10^12
Step-by-step explanation:
If it was addition, then she’d be correct;
6.75x10^6 + 0.2x10^6
= (6.75 + 0.2)x10^6
= 6.95x10^6
But really, it was a multiplication, meaning the answer really is;
(6.95x10^6)x(0.2x10^6)
= 1.39 x 10^12

Find the volume of the following cone.
Round your answer to one decimal place.
Answer:
429.4 cubic units
Step-by-step explanation:
Volume of a cone = pi*r^2*(h/3)
height = 9
radius = 6.75
pi*6.75^2*(9/3) = pi*45.5625*3 = 136.6875pi
136.6875*pi is around 429.416 -> rounded = 429.4
Answer:
See answer below.
Step-by-step explanation:
[tex]V = \frac{1}{3} \pi r^2h[/tex]
[tex]V = \frac{1}{3}\pi (6.75)^2(9)[/tex]
[tex]V = 3\pi (6.75)^2[/tex]
[tex]V = 136.6875\pi[/tex]
V = 136.68.76(3.14) or use solve with calculator π
[tex]V = 429.19876 \\V = 429.414458[/tex]
*What is the correct value of b?
~50/100 = b/28
-b=14
-b=20
-b=10
*What is the value of n?
~25/100 = 7/n
-n=28
-n=24
-n=32
Answer:
-b = 14
-n = 28
Step-by-step explanation:
For b
50/100=b/28 cross-multiply
1400= 100b divide both sides by hundred
-b = 14
For n
25/100= 7/n cross multiply
25n = 700 divide both sides by 25
-n = 28

Answer:
If there is a system of magnets being held in place, there is potential energy
Step-by-step explanation:
pretty sure you've seen this answer before but 8ts right so just go along with it ok bud?
Answer:
Okay
Magnets work because opposite poles are attracted to each other, this is how the objects move (depending on how the atoms and how to iron is, it could be much stronger or weaker)
If there is a system of magnets there is potential energy, when you let go of the magnets (or when they stick together) it converts the potential energy to kinetic energy because it moved.
