in the figure AB/CD. What are the values of x and y?
A: x=32, y=140
b: x=140, y=52
c: x=52, y=140
d: x=38, y=154
Answer:
C.
Step-by-step explanation:
interior angles for ABCD is 360° and for ABO(triangle above) is 180°
from triangle,
you will get angle for OBA which is 180° - 38° - 90° = 52°
from angle B, we know that, straight line is 180°.
so,
180° = 52° +y- 12°
y = 140°
so, we can calculate x.
360° = 90° + 90° + 128° + x
x = 52°
Brandy attaches some trim to create a decorative border around the edges of a circular

The Starks spend $84 on a meal out. If they want to leave a 22% tip, which of
the following expressions would determine their total?
84(0.22)
O 84(0.88)
84(0.78)
84 + 84(0.22)
84(1.22)
Help Please I need help Now
Answer:
84 + 84(0.22)
Step-by-step explanation:
In order to find the amount of the tip you need to do 84x0.22 then you add that on to the original price
Some IQ tests are standardized to a Normal model N(100,19). What is the cutoff value for the top 5% of all IQs
Answer:
The cutoff value for the top 5% of all IQs is 131.255.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 100, \sigma = 19[/tex]
What is the cutoff value for the top 5% of all IQs
This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 100}{19}[/tex]
[tex]X - 100 = 19*1.645[/tex]
[tex]X = 131.255[/tex]
The cutoff value for the top 5% of all IQs is 131.255.
The area of a rectangular dining room is 16 square meters. The perimeter is 16 meters. What are the dimensions of the dining room?
Answer:
4
Step-by-step explanation:
The area is 16, and you know that it's 2 sides u need to multiply
The perimeter is 16, and you know that you need to add up all the sides
So....
A = b * h
A = 4 * 4
A = 16 CORRECT
And....
P = S + S + S + S ( s = sides)
P = 4 + 4 + 4 + 4
P = 16 CORRECT
Hope this helped!

AaBbCc x AaBbCc (use for all 3 questions) 1. What is the probability that this individual will: AABBcc 2. What is the probability that this individual will: AaBBcc 3. What is the probability that this individual will: AaBbCc
Answer: 1. P = 1/64
2. P = 1/32
3. P = 1/8
Step-by-step explanation:
In genetics, an ofspring inherits one copy of an allele of each parent, which can be described in the tables below called Punnett Square:
For crossing Aa x Aa:
A a
A AA Aa
a Aa aa
For crossing Bb x Bb:
B b
B BB Bb
b Bb bb
For crossing Cc x Cc:
C c
C CC Cc
c Cc cc
We can separate them because they are assorted independently.
For offspring with genotype AABBcc, probability will be:
P(AA) = 1/4
P(BB) = 1/4
P(cc) = 1/4
As all three probabilities has to happen at the same time, it is a "E" rule:
P(AABBcc) = [tex](\frac{1}{4}) (\frac{1}{4}) (\frac{1}{4})[/tex]
P(AABBcc) = 1/64
Probability for the individual to be AABBcc is 1/64 or 1.56%.
Genotype AaBBcc:
P(Aa) = 2/4 = 1/2
P(BB) = 1/4
P(cc) = 1/4
P(AaBBcc) = [tex](\frac{1}{2}) (\frac{1}{4}) (\frac{1}{4})[/tex]
P(AaBBcc) = 1/32
Probability for the individual to be AaBBcc is 1/32 or 3.12%
Genotype AaBbCc:
P(Aa) = 1/2
P(Bb) = 1/2
P(Cc) = 1/2
P(AaBbCc) = [tex](\frac{1}{2}) (\frac{1}{2}) (\frac{1}{2})[/tex]
P(AaBbCc) = 1/8
Probability for the individual to be AaBbCc is 1/8 or 12.5%.

The width of a rectangle is 4y - 8.5 feet and the length is 8.5y + 10 feet. Find the perimeter of the rectangle.
Answer:
P = 25y + 3
Step-by-step explanation:
Draw out the figure. You should know that 2(width+length) = Perimeter.
Therefore, when you plug everything in, your expression should look like this:
2(12.5y+1.5) = P
In the end, since you don’t have any other information about y, your final answer would be 25y + 3 = P.

Patty wants a triangle garden in her backyard for all of her vegetables. She
is going to use three pieces of fencing that measure 7 feet, 10 feet, and 8
feet. Will her garden be in the shape of a right triangle? Why or why not?
Answer:
Step-by-step explanation:
the hypothenuse is the largest side in the right triangle
we have 2 side, 7,8
in a right triangle, c^2= a^2+b^2
where c is the hypothenuse
c^2=49+64=113
c=sqrt113=aprox 10.6
so, the answer is no if it has to be exactly 10 ft the hypotenuse
