Find m∠1 and m∠2. and Tell which theorem you use in each case.
Answers
The angles in the parallel lines are as follows;
m∠1 = 42 degreesm∠2 = 42 degrees.How to find angles when parallel lines are cut by a transversal?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, linear angles, vertically opposite angles etc.
Therefore, let's find the angles m∠1 and m∠2.
Hence,
138 + m∠1 = 180(angles on a straight line)
The sum of angles on a straight line is 180 degrees.
m∠1 = 180 - 138
m∠1 = 42 degrees
Therefore,
m∠1 = m∠2 (alternate exterior angles)
Alternate exterior angles are the pair of angles that are formed on th outer side of the parallel lines but on the opposite side of the transversal.
Alternate exterior angles are congruent.
Therefore,
m∠1 = m∠2 = 42 degrees.

Find the SURFACE AREA of the composite figure below
ASAP
Answers
Answer:
248.26 cm²
Step-by-step explanation:
Surface area of the composite figure = (surface area of cuboid + surface area of hemisphere) - 2(base area of hemisphere)
Surface area of cuboid = \( 2(lw + lh + hw) \)
Where,
l = 10 cm
w = 5 cm
h = 4 cm
Plug in the values into the formula:
\( SA = 2(10*5 + 10*4 + 4*5) \)
\( SA = 2(50 + 40 + 20) \)
\( SA = 2(110) = 220 cm^2 \)
Surface area of hemisphere = 3πr²
Where,
π = 3.14
r = 3 cm
SA of hemisphere = 3*3.14*3² = 3*3.14*9 = 84.78 cm²
Base area of hemisphere = πr²
BA = 3.14*3² = 3.14*9 = 28.26 cm²
Surface area of the composite shape = (220 + 84.78) - 2(28.26)
= 304.78 - 56.52
SA = 248.26 cm²

Where the above relations are given, note that Options A, D, and E are the relations that represents a function. The others are just relations.
How do you identify the relation that represents a function?To distinguish a function from a relation, look to see if any of the x values are repeated; if not, the relationship is a function. If some x values are repeated but the accompanying y values differ, we have a relation rather than a function.
Note that where you are given domain and range, only the range is represented on the x-axis.
Some of the x values may be seen repeated in B, and C.
How is this so?
B) In a coordinate system, values are represented as (x, y). so
In relations, B 2 is repeated twice to in connection with -5, and -6. That is:
(2, -5) , (2, -6)
Since two is x, then its repetition nullified the relation as a function.
C) On table indicated on C, it is much easier to identify the x and y values. As is seen, -3 is repeated twice in connection with 4 and 2. Thus, its repetition nullified the relation as a function.
As a result, Options A, D, and E are the relations that represent a function.

Answers
To calculate the simple interest, we use the following formula:
(Principal) • (interest rate) • (time) = simple interest
Plugging the values in, we will find that:
$2,750 (our principal) • 0.015% (our interest rate represented by a decimal) • 3 (our time period in years) = $123.75 (our simple interest)
Ultimately, Devi made an investment and in 3 years earned a simple interest of $123.75.

5) One in four people in the US own individual stocks. You randomly select 12 people and ask them if they own individual stocks. a) Find the probability that the number who say they own individual stock is greater than 10. b) Find the probability that the numbers who say they own individual stock is less than 10. c) Find the probability that the numbers who say they own individual stock is at least 10.
Answers
Answer:
a) 0.0002% probability that the number who say they own individual stock is greater than 10.
b) 99.9963% probability that the numbers who say they own individual stock is less than 10.
c) 0.0037% probability that the numbers who say they own individual stock is at least 10.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they own individuals stocks, or they do not. The probability of a person owning stocks is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
One in four people in the US own individual stocks.
This means that \(p = \frac{1}{4} = 0.25\)
You randomly select 12 people
This means that \(n = 12\)
a) Find the probability that the number who say they own individual stock is greater than 10.
\(P(X > 10) = P(X = 11) + P(X = 12)\)
In which
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 11) = C_{12,11}.(0.25)^{11}.(0.75)^{1} = 0.000002\)
\(P(X = 12) = C_{12,12}.(0.25)^{12}.(0.75)^{0} \approx 0\)
\(P(X > 10) = P(X = 11) + P(X = 12) = 0.000002 + 0 = 0.000002\)
0.0002% probability that the number who say they own individual stock is greater than 10.
b) Find the probability that the numbers who say they own individual stock is less than 10.
Either 10 or more say thew own, or less than 10 say. The sum of the probabilities of these outcomes is 1. So
\(P(X \geq 10) + P(X < 10) = 1\)
We want \(P(X < 10)\)
So
\(P(X < 10) = 1 - P(X \geq 10)\)
In which
\(P(X \geq 10) = P(X = 10) + P(X = 11) + P(X = 12)\)
\(P(X = 10) = C_{12,10}.(0.25)^{10}.(0.75)^{2} = 0.000035\)
\(P(X = 11) = C_{12,11}.(0.25)^{11}.(0.75)^{1} = 0.000002\)
\(P(X = 12) = C_{12,12}.(0.25)^{12}.(0.75)^{0} \approx 0\)
\(P(X \geq 10) = P(X = 10) + P(X = 11) + P(X = 12) = 0.000035 + 0.000002 + 0 = 0.000037\)
\(P(X < 10) = 1 - P(X \geq 10) = 1 - 0.000037 = 0.999963\)
99.9963% probability that the numbers who say they own individual stock is less than 10.
c) Find the probability that the numbers who say they own individual stock is at least 10.
\(P(X \geq 10) = P(X = 10) + P(X = 11) + P(X = 12) = 0.000035 + 0.000002 + 0 = 0.000037\)
0.0037% probability that the numbers who say they own individual stock is at least 10.
a) calculate the radius of the original large cone.
b) Calculate the volume of the frustum to the nearest integer.
Answers
a) The radius of the original large cone is approximately 9.4 m.
b) The volume of the frustum is approximately 617 m^3.
a) To calculate the radius of the original large cone, we can use the concept of similar triangles. In the given diagram, we have a frustum formed by removing a smaller cone from a larger cone.
The height of the frustum is 3 m, the radius of the larger base (R1) is 10 m, and the radius of the smaller base (R2) is unknown. The height of the larger cone (H) is 50 m.
Using the similar triangles formed by the frustum and the larger cone, we can set up the following proportion:
(R1 - R2) / h = R1 / H,
where h is the height of the frustum.
Substituting the known values, we have:
(10 - R2) / 3 = 10 / 50.
Simplifying the equation, we find:
(10 - R2) / 3 = 1/5.
Cross-multiplying and solving for R2, we get:
50 - 5R2 = 3,
5R2 = 47,
R2 ≈ 9.4 m.
b) To calculate the volume of the frustum, we can use the formula for the volume of a frustum of a cone:
V = (1/3) * π * h * (R1^2 + R2^2 + R1 * R2).
Substituting the known values, we have:
V = (1/3) * π * 3 * (10^2 + 9.4^2 + 10 * 9.4).
Evaluating this expression, we find:
V ≈ 616.62 m^3.
Rounding this value to the nearest integer, the volume of the frustum is approximately 617 m^3.

⇒ AB² = 49 + 100 - 140cos(73)
⇒ AB² = 149 - 140cos(73)
⇒ AB² = 149 - 140cos(73)
⇒ AB² = 149 - 140(0.292)

It is mentioned that there are 35 more blue balls than red balls. Therefore, the number of blue balls is 30 + 35 = 65.
The remaining balls are green, so the number of green balls is 110 - (30 + 65) = 15.
To find out how many more blue balls there are than green balls, we subtract the number of green balls from the number of blue balls: 65 - 15 = 50.

The salaries of 26 randomly sampled managers are used to estimate the mean of the population. What t-score should be used to find the 95% confidence interval for the population mean
Answers
Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
