Answer:
32% probability that a randomly selected adult in North Dakota will be a female who has enrolled in college.
Step-by-step explanation:
We have these following probabilities:
48.6% probability that a randomly selected adult in North Dakota is a female.
If a randomly selected adult in North Dakota is over 18, 65.9% probability that they have enrolled in college at some point in their lives.
These events are independent.
This means that to find the probability that a randomly selected adult in North Dakota will be a female who has enrolled in college, we can just multiply these probabilities.
P = 0.486*0.659 = 0.32 = 32%
32% probability that a randomly selected adult in North Dakota will be a female who has enrolled in college.
Answer:
the probability that a randomly selected adult in North Dakota will be a female who has enrolled in
college is 32%
Step-by-step explanation:
Given;
48.6% of the North Dakota population over 18 years old is female
P(f) = 48.6% = 0.486
65.9% of the total population of North Dakota over 18 years old has enrolled in college at some point in their lives;
P(c) = 65.9% = 0.659
Since, these two events are independent of each other, the probability that a randomly selected adult in North Dakota will be a female who has enrolled in
college is;
P(f∩c) = P(f) × P(c) = 0.486 × 0.659 = 0.320274
P(f∩c) = 0.32
P(f∩c) = 32%

Can you explain how to find the dimensions fro this rectangle
Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5
Answer:
Length = 7.5 and width =- 4.5.
Step-by-step explanation:
We have the equation:
P = 2L + 2W where P = perimeter, L = length and W = width.
Here P = 24, L = x + 3 and W = x
So plugging in the given values:
24 = 2(x + 3) + 2x
4x + 6 = 24
4x = 24 - 6 = 18
x = 4.5.
So the dimension ar length = x + 3 = 7.5 and width = 4.5.

I predict it will take 23 minutes to drive to my grandma's house today. It actually takes 24 minutes. What is the percent error? Round to the nearest thousandth.
Answer:
4.167%
Step-by-step explanation:
Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.
To find: percent error
Solution:
Predicted time = 23 minutes
Actual time = 24 minutes
Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.
Error = 24 - 23 = 1 minute
Percent error = (error/actual time) × 100
= 4.167%

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking an even number and then picking an even number?
Simplify your answer and write it as a fraction or whole number.
Answer:
Probability of picking an even and then even number = [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Probability of picking a card with even number,
P(even 1) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex] = [tex]\frac{\text{even cards}}{\text{Total number of cards}}[/tex]
= [tex]\frac{2}{4}[/tex]
= [tex]\frac{1}{2}[/tex]
Followed by picking a card which is even without putting the first card back.
So an even card is to be picked out of remaining 3 cards.
P(even 2) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]
= [tex]\frac{1}{3}[/tex]
Now probability of both events = P(even 1) × P(even 2)
= [tex]\frac{1}{2}\times \frac{1}{3}[/tex]
= [tex]\frac{1}{6}[/tex]
Therefore, probability of both the events will be [tex]\frac{1}{6}[/tex].

p = 7000 is the amount deposited, aka the principal
r = 0.15 is the decimal form of 15% interest rate
t = 2 is the number of years the money sits in the account
--------------
B = p*(1+r)^t
B = 7000*(1+0.15)^2
B = 7000*(1.15)^2
B = 7000*(1.3225)
B = 9257.50
Subtract off the deposited amount to get the interest earned
i = B - p = 9257.50 - 7000 = 2257.50

The lengths of the pieces of lumber that a carpenter has are shown in the table.
2 ft 3 ft 6 ft 1.5 ft 4.5 ft 1 ft
3. Find the mean length. 4. Find the median length.
Answer:
The mean length is 3 ft
while the median length is 2.5 ft
Step-by-step explanation:
The mean length is the sum of the lengths divided by the count of the lengths.
Mathematically, that is;
(2 + 3 + 6 + 1.5 + 4.5 + 1)/6 = 18/6 = 3 ft
To calculate the median length, we first need to rearrange the lengths in increasing order
1, 1.5, 2, 3, 4.5, 6
Now, looking at these lengths, the middle lengths are 2ft and 3ft
we can add both together and divide by 2
That would be (2+3)/2 = 5/2 = 2.5 ft
Answer:
Mean length = 3ftMedian length = 2.5ftStep-by-step explanation:
Given the lengths of the pieces of lumber that a carpenter has as shown;
2 ft, 3 ft, 6 ft, 1.5 ft, 4.5 ft, 1 ft
3) The mean length is expressed as the ratio of the sum total of the lengths to the total amount of pieces of lumber given.
Mathematically; Mean ([tex]\overline x[/tex]) = [tex]\frac{\sum Xi}{N}[/tex]
Xi is the individual length
N is the total amount of pieces of lumber = 6pieces
[tex]\overline x = \frac{2+3+6+1.5+4.5+1}{6} \\\overline x = \frac{18}{6} \\\overline x = 3ft[/tex]
4) Median is the value at the middle of the given lengths after rearrangement. Rearrangement can either be ascending or descending.
Rearranging the data in ascending order we have;
1ft, 1.5ft, 2ft, 3ft, 4.5ft, 6ft
The two lengths at the middle are 2ft and 3ft. Taking the average of the two values since we cannot have 2 median values.
Median = 2+3/2
median = 2.5ft

You flip a coin and then roll a fair six-sided die. Find probability the coin lands heads-up and the die shows a five
Answer:
A "fair" coin lands heads-up half of the time and "tails-up" half of the time.
For one flip, the probability of landing heads-up is 1/2.
Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.
So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.
Step-by-step explanation:
The probability that coin lands heads-up and the die shows a five is 0.083.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.
Given that, a person flip a coin and then roll a fair six-sided die.
The probability the coin lands heads-up is 1/2
The probability that die shows a five = 1/6
Now, the probability of an event = 1/2 × 1/6
= 1/12
= 0.083
Therefore, the probability that coin lands heads-up and the die shows a five is 0.083.

How to solve for a missing side length of a triangle (NOT a right triangle) when one side is 4m and another side is 3m, and the only angle is 120 degrees?
Answer:
c ≈ 6.08 m
Step-by-step explanation:
Your question is how to solve for a missing side length of a triangle when given 2 sides length and an angle. The side length can be solved using the cosine rule . We use cosine rule to find the length of a side of a triangle when given two sides and an included angle.
The cosine rule formula for finding a side length are as follows
c² = a² + b² - 2ab cosC
b² = a² + c² - 2ac cosB
c² = a² + b² - 2ab cosC
Using cosine rule
c² = 4² + 3² - 2 × 4 × 3 cos 120°
c² = 16 + 9 - 24 cos 120°
c² = 25 - 24 (-0.5)
c² = 25 + 12
c² = 37
square root both sides
c = √37
c = 6.0827625303
c ≈ 6.08 m

The volume of the figure is about...(whole number as needed).
Answer:
1,590.7 cm^3
Step-by-step explanation:
First, separate this shape into two smaller shapes you can easily find the volume of. In this example, you can separate this figure into a cone and a half-sphere.
Find the volume of the cone using the formula: V=πr^2(h/3). The radius is 7 because 14cm is the diameter, and 17cm is the height. When you solve, you get 872.32 for the volume of this cone.
Then, find the volume of the half-sphere. The volume of a sphere can be found with the formula: V=4/3πr^3. The radius is, again, 7. Now divide this value in half because you only want to find the volume of a half-sphere. You should get 718.38 cm.
Now add the two volumes together to get 1,590.7 cubed centimeters.
Step-by-step explanation:
volume of hemisphere
given
r=d/2=14/2=7cm
V=2/3πr^3
V=2/3×π×7^3
V=2/3×π×343cm^3

r=7cm
h=17cm
V=πr^2×h/3
V=π×7^2×17cm/3
V=π×49cm^2×17cm/3

V=2616.94/3
V=872.31cm^3
