Answer:
163°.
Step-by-step explanation:
Sum of any pentagon is 540°.
So.
x + 68° + 121° + 103° + 85° = 540°.
x + 377° = 540°.
x = 540° - 377°
x = 163°.

Lines L and M are parallel find the measure of angle 7
9514 1404 393
Answer:
∠7 = 142°
Step-by-step explanation:
Angle 7 and the one marked 38° form a linear pair. The fact that line L exists and is parallel to line M is irrelevant to this question. Angles of a linear pair are supplementary, so ...
∠7 = 180° -38° = 142°
_____
Additional comment
Because lines L and M are parallel, all of the obtuse angles in this geometry have the same measure as angle 7. Likewise, all of the acute angles are congruent to 38°.
∠1 = ∠3 = ∠5 = ∠7 = 142°
∠2 = ∠4 = ∠6 = 38°

Ana has a bag of skittles. The number of skittles and the different colors of the skittles are listed: 8 red , 6 blue , 3 green , 6 yellow Ana will choose two skittles at random. What is the probability that Ana chooses a blue skittle first, eats it, and then selects a skittle that is not yellow?
Answer:
The probability of her not choosing yellow is 6/22.
Step-by-step explanation:
The probability that she chooses a blue skittle is 6/23 since she eats one blue skittle the total decreases to 22. So the probability of her not choosing yellow is 6/22
At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample.
Starting on line 1 of the random-number table, how many left-handed students occur in the first trial of the simulation if we let 00-14 represent left-handed students?
=============================================================
Explanation
We start in the first row at the very left side. The first two digits are the '2' and '4', and they form the value 24. Since 24 is not in the interval from 00 to 14, this means that the first randomly selected student is not left-handed.
The next two digits are 0 and 0. This forms 00 and represents a left-handed student because now we are between 00 and 14. Make a tally of how many left-handed students you count.
As we keep reading across the row, the next two digits are 0 and 7 and they combine to 07. This is another left handed student. However, the student after that is not left-handed since 59 is not in the range from 00 to 14.
Here's a list of all the values we read from the table, and if they're left handed or not:
table value = 24, not left-handedtable value = 00, left-handed (1 so far)table value = 07, left-handed (2 so far)table value = 59, not left-handedtable value = 83, not left-handedtable value = 62, not left-handedtable value = 20, not left-handedtable value = 09, left-handed (3 so far)table value = 15, not left-handedtable value = 18, not left-handedThere are 3 left-handed people in our sample. The table values were: 00, 07, and 09 in that order from left to right.
So that's why the answer is 3.
If you start at another point in the random-number table, then it may be likely that you'll get a different answer. Also, if you decide to read the table in a different way, then you may likely get a different answer.

Answer:
Tn=a + (n-1)d
a= first term = 14
n= This is the term you're looking for... In this case... That's the 73rd term
d=Common difference (since its an AP)
d= second term - first term -- Or 3rd term - 2nd term = 23-14
d=9
T = 14 + (73-1)9
T= 14 + (72)9
T= 14 + 648
T=662.
The 73rd term would be 662.
1 term is +9
10 terms is +90
90x7=630
9x2=18
630+18=648
648+14=662

0 = pi/3 radians. Identify the terminal point and tan 0.
The terminal point is (0.5, 0.866), and the value of the tangent is 0.173.
How to identify the terminal point?For any angle a, the coordinates of the terminal point are given by:
x = cos(a)
y = sin(a).
In this case, the angle is a = pi/3
Then the coordinates of the terminal point are:
x = cos(pi/3) = 0.5
y = sin(pi/3) = 0.866
So the terminal point is ( 0.5, 0.866)
And the tangent of that angle is equal to the quotient between the y-component and the x-component:
tan(pi/3) = 0.866/0.5 = 0.173

Suppose a normal distribution has a mean of 50 and a standard deviation of
5. What is the probability that a data value is between 48 and 52? Round your
answer to the nearest tenth of a percent.
Answer:
27.8% I think
Step-by-step explanation:
Then standardize the two scores
48 and 52
to be able to consult the table.
The formula for changing a raw score x into a z score is
Z=X−μσ.
For this problem, X is normal with
μ=50 and σ=5.
So, by symmetry of the standard normal curve,
P(48<X<52)
=P(48−50<X−50<52−50)
=P(48−505<X−505<52−505)
=P(−25<Z<25)
=P(−.40<Z<.40)
=P(Z<.40)−P(Z<−.40)
=P(Z<.40)−P(Z>.40)
=P(Z<.40)−(1−P(Z<.40))
=2P(Z<.40)−1
=2(.6554)−1
=1.3108−1
=.3108≈.31
=31%.

Determine the scale factor for A ABC to A A'B'C:
A. 1/2
B. 10
C. 5
D. 2
The required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.
The scale factor of the ΔABC to ΔA'B'C' is to be determined, while one of each side of the triangle has lengths 5in and 10 in respectively.
The scale factor is defined as the ratio of modified change in length to original length.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Since the scale factor only applies to similar shapes so as the two triangles are similar then the ratio of the side will describe the scale factor between two triangles.
Scale factor = A'C'/AC
= 10 /5
= 2 in
Thus, the required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.
