Answer:
7/22
Step-by-step explanation:
From the question given above, the following data were:
Drama n(D) = 25
Sport n(S) = 140
Both drama and sport n(DnS) = 60
Not in drama or sport n(DnS)ᶜ = 105
Total or sample space n(S) = 330
Probability of not in drama or sport P(DnS)ᶜ =?
The probability that the student chosen is not in drama or sport can be obtained as follow:
P(DnS)ᶜ = n(DnS)ᶜ / nS
P(DnS)ᶜ = 105 / 330
Express the above to its lowest terms
P(DnS)ᶜ = 7/22
Therefore, the probability that the student chosen is not in drama or sport is 7/22
The figure shown has two parallel lines cut by a transversal: A pair of parallel lines is shown, crossed by a transversal. Angles are identified as 1, 2, 3, 4, 5, 6, 7, and 8. Angles 1-4 are on the top line clockwise from upper left. Angles 5-8 are on the lower line clockwise from upper left. Use the figure to complete the sentence. ∠7 and ____ are alternate exterior angles. ∠2 ∠1 ∠5 ∠8
*see attachement for the diagram of the figure being referred to
Answer:
<1
Step-by-step explanation:
Alternate exterior angles are a pair of angles which are located on the opposite side of the transversal, outside the two parallel lines.
From the figure given, you would see that <7 and <1 lie on opposite side of the transversal and they lie on the outside of the two parallel lines that are cut across by the transversal.
Therefore:
<7 and <1 are alternate exterior angles.
help me please asap!!!
Answer:
122°
Step-by-step explanation:
<ADC is an inscribed angle and its measure is equal to half of the arc it sees (minor arc AC)
if ADC is 61° then minor arc AC is 2 × 61 = 122
ABC is the center angle and so its measure is equal to the arc it sees which is 122°

The zoo has 4 tigers and plans to adopt more tigers soon. Gabby meets with Chloe, the manager of the tiger exhibit, to discuss the tigers’ habitat. They want to make sure there is enough space for the new tigers.
The Natureland Zoo has these requirements for a tiger habitat:
The trees, feeding station, and drinking station need at least 300 square feet all together.
Each tiger needs at least 225 square feet of space.
How many square feet of space is the zoo required to have for 4 tigers? Show your work.
Answer:
multiple 4×225 because there are 4 tigers and one Tiger needs 225 square feet so mutiple 4×225 and you got 900 so the answer will be 900 square feet
A report describes the results of a large survey that was conducted for the Center for Disease Control (CDC). The sample was selected in a way that the CDC believed would result in a sample that was representative of adult Americans. One question on the survey asked respondents if they had learned something new about a health issue or disease from a TV show in the previous 6 months. Data from the survey was used to estimate the following probabilities, where
L = outcome that a randomly selected adult American reports learning something new about a health issue or disease from a TV show in the previous 6 months
and
F = outcome that a randomly selected adult American is female
Data from the survey were used to estimate the following probabilities:
P(L)= 0.58 P(F)= 0.50 P(L and F)= 0.31
Are the outcomes L and F independent? Use probabilities to justify your answer.
Answer:
Since [tex]P(L \cap F) \neq P(L)P(F)[/tex], the outcomes L and F are not independent.
Step-by-step explanation:
Independent events:
Two events, A and B are independent, if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
Are the outcomes L and F independent?
We are given that:
[tex]P(L \cap F) = 0.31[/tex]
Multiplication of the probabilities:
[tex]P(L)P(F) = 0.58*0.5 = 0.29[/tex]
Since [tex]P(L \cap F) \neq P(L)P(F)[/tex], the outcomes L and F are not independent.

Which statements describe valid ways to rewrite a percent as a fraction? Check all that apply.
Write a fraction using the percent over 10 and simplify.
Write a fraction using the percent over 100 and simplify.
Divide the percent by 100, write it as a fraction, and simplify.
Multiply the percent by 100, write it as a fraction, and simplify.
Answer:
Write a fraction using the percent over 100 and simplify. AND. Divide the percent by 100, write it as a fraction, and simplify.
Step-by-step explanation:
Let's test all the answers and see which statements are true.
Let's just use 50 as the percent to test it. These statements should end up looking like [tex]\frac{1}{2}[/tex]
Write a fraction using the percent over 10 and simplify.
[tex]\frac{50}{10} =5[/tex], half of ten is 5, so this makes it invalid.
Write a fraction using the percent over 100 and simplify.
[tex]\frac{50}{100} =\frac{1}{2}[/tex], this is valid.
Divide the percent by 100, write it as a fraction, and simplify.
[tex]\frac{50}{100} =\frac{1}{2}[/tex], valid!
Multiply the percent by 100, write it as a fraction, and simplify.
[tex]50*100=500[/tex], invalid.
The two valid statements are: Write a fraction using the percent over 100 and simplify. AND. Divide the percent by 100, write it as a fraction, and simplify.

Help!! Pythagorean theorem
Answer:
The Pythagorean theorem only works for right triangles. This is not a right triangle.
x = 23
All interior angles of a triangle = 180 degrees.
A + B + C + 180
(3x) + (2x+12) + (2x+7) = 180
7x + 19 = 180
7x = 161
x = 23
A = 3(23) = 69 degrees
B = 2(23) + 12 =58 degrees
C = 2(23) + 7 = 53 degrees
Answer:
x=23
Step-by-step explanation:
u see this is how the Pythagorean theorem works a^2 + b^2 = c^ i hope this helps have a great day bye please mark as brainliest :D

How do u turn 4 into a fraction
Answer:
4/1
Step-by-step explanation:
Multiply both the numerator and denominator by the value you chose in step 2. So to turn the whole number 4 into halves, you would multiply 4/1 by 2/2 and reach a value of 8/2. This completes the conversion of the whole number four into a fraction.
Answer:
4/1
Step-by-step explanation:
u put it over 1. Any whole number over one is considered a fraction, but its still the same number.
Five houses in the neighborhood sold this month for the following prices:
$328,000, $297,500, $415,000, $389,000, $345,000.
The house with the highest selling price sold for how much more than the median selling price?
Answer:
70,000
Step-by-step explanation:
Median= 345,000
Higest selling house= 415,000
415,000-345,000= 70,000

increasing on 0 < x < 2f(2) = 4decreasing on 2 < x < 5Step-by-step explanation:
You need to know that an even function is symmetrical about the y-axis. The graph to the right of the y-axis is the mirror image of the graph to the left. With that in mind, the questions are easily answered.
It might help to draw the function graph, as we did in the attached. Then it is more straightforward to see what is happening in each of the intervals.
The function is increasing in the interval 0 < x < 2.
The function value at x=2 is 4: f(2) = 4.
The function is decreasing in the interval 2 < x < 5.
