Find m∟1 and m∟2. Tell which theorem can be use
Answer: Angle 1 = 150 - corresponding angles
Angle 2 = 150 - alternate exterior angles
Step-by-step explanation:
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
From the given figure measure of one of the angle is 150°.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size. They are either both obtuse or both acute.
Here, ∠1 = 150° (Corresponding angles)
∠1 =∠2 = 150° (Vertically opposite angles are congruent)
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.

A recent report indicated that 22 percent of the households in a certain community speak a
language other than English at home. A reporter will randomly select a household from the
community until the first houehold that speaks a language other than English at home is
selected. Let random variable Q represent the number of attempts needed until the first
household that speaks a language other than English at home is selected. The random variable
Q has a geometric distribution with p = 0.22. Which of the following is closest to the variance
of the random variable?
Answer:
16.1157
Step-by-step explanation:
The random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.
What is the variance of the random variable?A spread measure for a random variable distribution quantifies how much the values of a random variable deviate from the value that is predicted.
For a discrete random variable, the variance is determined by adding the square of the difference between the value of the random variable and the anticipated value, together with the chance that the value of the random variable will occur, across all of the values of the random variable.
It is given that 22 percent of people in the community speak a language other than English at home.
The required number of tries should be represented by the random variable Q.
The geometric distribution of the random variable Q has a p-value of 0.22.
The variance of a random variable is
V(Q) = (1-p)/p²
V(Q) = (1-0.22)/(0.22)²
V(Q) =0.78/0.484
V(Q) =16.1157
Thus, the random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
Request you to finish this please
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.

Need help with a few geometry questions !?!?
Answer:
1. ACB, CDB and ADC are all similar to eachother.
2. 10
3. CD=8, AD=10.666667, AC=13.33333
4. X=2.4
5. X=√10
6. X=√15
Step-by-step explanation:
1. To prove triangles are similar, prove they share at least two angles.
Triangle ACB is similar to triangle CDB because they both share a 90° angle and ∠B.
Triangle ACB is similar to triangle ADC because they both share a 90° angle and ∠A.
Since ACB is similar to both CDB and ADC respectively, CDB is similar to ADC.
2. Use similar triangles to find AB
ACB is similar to CDB
AB/CB=CB/DB
AB/10=10/6
AB=100/6=16.666667
Geometric mean: √(16.66667*6)=10
3.
Find CD using Pythagorus:
10²=6²+CD²
CD²=100-36
CD=√64=8
Use similar triangle ratios to find AD:
CDB is similar to ADC.
CD/DB=AD/DC
8/6=AD/8
AD=8(8/6)=10.6666666667
Find AC using Pythagorus:
AC²=10.66666666667²+8²
AC=√177.7777777778
AC=13.333333333
4. √(40²+30²)=50
30/50=X/40
X=2.4
5. (√35)²=X²+5²
35=X²+25
X=√10
6. √((√10)²-(√6)²=√(10-6)=2
√6/2=X/√10
6/4=X²/10
X²=10(1.5)
X=√15

We could simply the ratio to?
Answer:
See below.
Step-by-step explanation:
3.)
There are 4 oranges and 6 apples so the fraction would be 4/6 which we can reduce to 2/3.
a.) As we stated beforehand, the fraction was 2/3. That means for every 2 oranges, there are 3 apples.
b.) We did this already. 4/6 was reduced to 2/3.
