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

First, find the probability that you will pull a yellow marble. There are 9 yellow marbles and 22 total, so the probability is 9/22. Then, find the probability that you will pull a green marble. There are 7 green out of 22 so the probability is 7/22. To find the probability of both, multiply them.
9/22 * 7/22 is 63/484

Step-by-step explanation:
We can first multiply the 2 and 4 together to get 8.
Wow we already eliminated A.
When you have negative powers, you can just replace it with their inverse and turn the power positive.
For example, 2 to the power of -3 (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).
So we now have 8 (x^4 / yx^2
We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.
For example, x^5 divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.
So we have 8 ( x^2y)
So 8x^2 y

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°

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.

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

In the xy-plane, what is the y-intercept of the graph of the equation y = square root of 4-x
a. 16
b. 4
c. 2
d. no y-intercept
y intercept of the graph of equation y = square root of 4-x is 2
Hence option c 2 is correct.
y = [tex]\sqrt{4-x}[/tex]
equation is the relationship between variable and represented as is example of polynomial equation.
at x = 0
y = [tex]\sqrt{4-0}[/tex]
y = 2
Hence, y intercept is 2
Thus, y intercept of the graph of equation y = square root of 4-x is 2

Split this figure out. Find the area of the square, as well as the rectangle.
First, the square
A= 4 x 3
A= 12 ft^2
Therefore, the square has an area of 12ft^2.
Then, the rectangle.
We must first find the length of the unknown side.
We have two measurements of 3ft on each side, as well as the middle measurement of 4ft.
So,
3+3+4=10
Now, find the area.
A= 2 x 10
A=20ft^2
Add the areas.
20+12=32ft^2
Therefore, the area of the figure is 32ft^2.
I hope this is correct. Best of luck.
