What is the probability that a randomly selected student who lives in Nebraska plans to stay in his or her home state after graduation? Round your answer to the nearest hundredth.
Answer:
[tex]P (Yes | Nebraska) = 0.10[/tex]
Step-by-step explanation:
Given
See attachment for contingency table
Required
[tex]P (Yes | Nebraska)[/tex]
From the contingency table, we have:
[tex]P (Yes\ n\ Nebraska) = 0.044[/tex]
[tex]P (No\ n\ Nebraska) = 0.400[/tex]
The required can be represented as:
[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]
Where
[tex]P (Nebraska) = P (No\ n\ Nebraska) +P (Yes\ n\ Nebraska)[/tex]
So, we have:
[tex]P (Nebraska) = 0.400 + 0.044[/tex]
[tex]P (Nebraska) = 0.444[/tex]
So, we have:
[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]
[tex]P (Yes | Nebraska) = \frac{0.044}{0.444}[/tex]
[tex]P (Yes | Nebraska) = 0.10[/tex] --- approximated

Answer:
[tex]30[/tex]; Obtuse, isosceles triangle OR "[tex]B[/tex]"
Step-by-step explanation:
If you replace the [tex]z^o[/tex] variable with [tex]30^o[/tex] on both angles.
The angles will be:
[tex]30^o[/tex]
[tex]120^o[/tex] ([tex]4(30)=120^o[/tex])
[tex]30^o[/tex]
This angle is isosceles (two sides are equal). It is obtuse (there is one angle that is greater than [tex]90^o[/tex]).

A cone has a radius of 5 cm and a height of 12 cm. What is the volume of the cone rounded to the tenth? Use pi = 3.14
Answer:
942m^3
Step-by-step explanation:
Given data
Radius of cone= 5m
Height= 12 m
We know that volume of a cone is given as
V= πr^2h
V= 3.14*5^2*12
V= 3.14*25*12
V= 942 m^3
Hence the volume is 942m^3

Write each ratio in fraction form. Then write the percent equivalent.
9. 88 out of 132
Answer:
Step-by-step explanation:
=9.88/132 (this is in fraction form)
for calculating percentage just multiply the fraction by 100%
=9.88/132*100%
=9.88*100/132
=988/132
=7.48 %
Anna's class has already collected 74 cans for the annual canned food drive. Her class
must collect more than 200 cans to reach their goal. The class plans to collect 15 cans
each day. Which inequality shows the number of additional days, d, Anna's class
needs to reach the goal?
CLEAR
15d + 74 > 200
15d - 74 > 200
15d + 74 > 200
150 – 74 > 200
Answer:
15d + 74 > 200
d > 8.4 days
Step-by-step explanation:
Total cans needed = over 200
Number of cans they have = 74
Number of cans needed per day = 15
Number of days = d
The inequality is
74 + 15d > 200
Also written as
15d + 74 > 200
15d > 200 - 74
15d > 126
d > 126/15
d > 8.4 days
Answer:
15d + 74 > 200
d > 8.4 days
Step-by-step explanation:
Total cans needed = over 200
Number of cans they have = 74
Number of cans needed per day = 15
Number of days = d
The inequality is
74 + 15d > 200
Also written as
15d + 74 > 200
15d > 200 - 74
15d > 126
d > 126/15
d > 8.4 days

A rolled up sleeping bag and shaped like a cylinder with a radius of 5" and a volume of 1727.9 cubic inches. What is the height of the road up sleeping bag?
Answer:
I think the height is 22.
please answer for points
Answer:
4.9
Step-by-step explanation:
use this equation : [tex]a^2 + b^2 = c^2[/tex] (your hypotenuse is always going to be c)
[tex]7^2 - 5^2 = b^2[/tex]
[tex]49 - 25 = b^2\\[/tex]
[tex]24 = b^2[/tex]
[tex]\sqrt{24} = b[/tex]

what’s the correct answer
Answer:
D
Step-by-step explanation:
I read an article saying that in the full population, there's a significant, positive correlation between the strength of your hand (grip strength) and the strength of your upper arm (arm strength). I want to see if that's true, and I have devices that can measure this accurately. I gathered a sample of average, healthy 21-year-olds and measured these two variables. My results were non-significant. Why didn't I find a significant correlation
Answer:
Restricted Range
Step-by-step explanation:
Required
Reason for insignificant correlation
From the question, we understand that the article discussed the full population while you restricted the correlation to only 21-year-olds age groups.
You left out other age groups included in the original dataset that was analyzed and reported by the article. The term that describes this act is restricted range, because other age groups are not represented in your analysis.

Let which means
Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.
To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.
So, we can rewrite as:
......(1)
Now, let us multiply the above with 10.
....... (2)
Now, let us subtract (1) from (2):
So, in simplified fractions:

Answer:
the surface area is 112 ft^2
Step-by-step explanation:
if you separate listen to two different rectangles you get what's a rectangle a being 3 + 10 + 3 equals 16 * 2 what gives you 32 okay and rectangle b being 3 + 2 + 3 what gives you 8 x 10 that gives you the area of 80 now you add the area both rectangles being 32 + 80 and to get a hundred and twelve feet squared

Write a polynomial in factored form that has the given zeros:
Zero at -4 with multiplicity of 2
Zero at 5 with multiplicity of 3
Answers to choose from.
1. f(x)=(x-4)^2(x+5)^3
2. f(x)=(x-2)^-4(x+3)^5
3. f(x)=(x+4)^2(x-5)^3
4. f(x)=(x+2)^-4(x+3)^5
Answer:
f(x) = (x + 4)^2*(x - 5)^3
Step-by-step explanation:
For a polynomial P(x) with zeros (or roots):
x₁, x₂, ..., xₙ
And a leading coefficient (the one that multiplies the term of highest degree) A, we can write the polynomial as:
P(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
Now, some of these roots can be repeated.
For example if x₁ = x₂
Then we say that the root x₁ has a multiplicity of two.
And we write the polynomial as:
P(x) = A*(x - x₁)^2*(x - x₃)*....*(x - xₙ)
Now, if we have a polynomial with the roots (or zeros):
Zero at -4 with a multiplicity of 2 (we have the root x = -4 two times)
Zero at 5 with a multiplicity of 3 (we have the root x = 5 3 times)
(And a leading coefficient A = 1, I assume)
This polynomial will be written as:
f(x) = (x - (-4))*(x - (-4))*(x - 5)*(x - 5)*(x - 5)
f(x) = (x + 4)*(x + 4)*(x - 5)*(x - 5)*(x - 5)
f(x) = (x + 4)^2*(x - 5)^3
The correct option is the third one:

8 x 4i x -12i -6i^2
6i^2 - 12i x 32
Step-by-step explanation:
Answer:
6i² - 8i + 8
Step-by-step explanation:
1. Expand Brackets: 8 + 4i - 12i - 6i²
2. Simplify equation: 8 - 8i - 6i²
3. Rearrange: 6i² - 8i + 8
Solve 1/3(x-9)=2x+7
X=6
X=2
X=-6
X=-2
Answer:
x = -6
Step-by-step explanation:
1/3(x-9)=2x+7
1/3x - 3 = 2x + 7
-5/3x = 10
x = -6
what's the value of x and y?
Answer:
x = 55
y = 70
Step-by-step explanation:
since it's all sides are equal its an equilateral triangle
each angle of an equilateral triangle is 60°
therefore,
y - 10 = 60 => y = 60 + 10
y = 70
x + 5 = 60 => x = 60 - 5
x = 55
Answer:
x+5=y-10
x-y = -15
y-10+X+5+X+5=180
2x+y =180
x-y+2x+y =180-15
3x.=165
x. =55
2x+y =180
y =180-(110)
y =70
