Determine the sum of the measures of the indicated angles.
Answer: 720 deg
Step-by-step explanation:
The given angles are just all the interior angles in 2 quadrilaterals
So since the sum of the int. angles in 1 quadrilateral is 360 deg, the sum in 2 is 720 deg
Solve for x. Explain.
Show your work in the space provided
Answer:
X=7
Step-by-step explanation:
Both are equal angles( the little 2 arrows prove that) so we set up the equation like this
75=11x-2
We need to isolate x to solve for it so we add 2 to both side since it's the opposite of subtraction.
our equation will then look like this
77=11x
last but not least, we divide 11 to both sides since it's the opposite of multiplication which 11 and X are doing
the answer is 7

CAN SOMEONE GIVE A EXPLAINATION ABOUT CLOSURE PROPERTY WITH A SIMPLE EXAMPLE THAT IS EASY TO UNDERSTAND
Explanation:
A set is "closed" for a particular operation if performing that operation on members of the set always gives a member of the set.
closed example
For example, the set {0, 1} is closed for multiplication:
0 × 0 = 0
0 × 1 = 0
1 × 1 = 1 . . . all result values are members of the set
Performing multiplication on any two members of the set gives a member of the set.
__
not closed example
The same set {0, 1} is not closed for addition:
0 +0 = 0
0 +1 = 1
1 +1 = 2 . . . not a member of the set
Performing addition on any two members of the set does not always give a member of the set.
_____
Additional comment
Sometimes you are asked to demonstrate closure of a particular set using a particular example. As we see with addition, above, some examples may seem to demonstrate closure, while another example may prove the set is not closed. In short, you can demonstrate that the set is closed for a particular operation on a particular example, but that does not demonstrate closure in general.

Error Analysis Allie says JKL ~ XYZ
What is Allie's error?
Similar triangles may or may not have equal measures
Allie's error is that Allie did not state the similarity theorem
How to determine Allie's errorThe statement JKL ~ XYZ means that:
Triangles JKL and XYZ are similar triangles
From the complete question, we have the following highlights:
Angles J and X have equal measures of 55 degreesThe side lengths of triangle XYZ are 3 multiplied by the corresponding side lengths of triangle JKLThe above means that, both triangles are similar by SAS or SSS
In Allie's statement, the similarity theorem is not stated
Hence, Allie's error is that Allie did not state the similarity theorem

Rationalize the denominator!
Question in the picture
Answer:
A
Step-by-step explanation:
[tex]\frac{10}{9+\sqrt{7} }[/tex]
To rationalise the denominator multiply the numerator and denominator by the conjugate of the denominator.
the conjugate of 9 + [tex]\sqrt{7}[/tex] is 9 - [tex]\sqrt{7}[/tex]
= [tex]\frac{10(9-\sqrt{7}) }{(9+\sqrt{7})(9-\sqrt{7}) }[/tex] ← expand denominator using FOIL
= [tex]\frac{90-10\sqrt{7} }{81-7}[/tex]
= [tex]\frac{90-10\sqrt{7} }{74}[/tex] ( divide terms on numerator/ denominator by 2 )
= [tex]\frac{45-5\sqrt{7} }{37}[/tex] → A
Answer:
A[tex]\frac{45-5\sqrt7}{37}[/tex]
Step-by-step explanation:
Easy. First let's multiply numerator and denominator by [tex]9-\sqrt7[/tex] since we will create a difference of squares to get rid of the root, then start doing the calculations
[tex]\frac{10(9-\sqrt7)}{(9+sqrt7)(9-\sqrt7)}=\frac{10(9-\sqrt7)}{81-7} = \frac{10(9-\sqrt7)}{74} =\\\frac{5(9-\sqrt7)}{37}=\frac{45-5\sqrt7}{37}[/tex]
A candy company claims that 31% of the candies are orange. We randomly sample 100 candies. We wish to know the probability our sample is 29% orange candies or less. Round answers to 4 decimal places and answer numerically (0.31, not 31%)
Find the probability our sample is 29% orange candies or less P(x<0.29)
Using the normal distribution and the central limit theorem, it is found that:
P(x < 0.29) = 0.2981.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It 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, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].In this problem:
31% of the candies are orange, hence p = 0.31.We randomly sample 100 candies, hence n = 100.Then, the mean and the standard error are given by:
[tex]\mu = p = 0.31[/tex]
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.31(0.69)}{100}} = 0.04625[/tex]
The probability our sample is 29% orange candies or less is the p-value of Z when X = 0.29, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.29 - 0.31}{0.04625}[/tex]
[tex]Z = -0.43[/tex]
[tex]Z = -0.43[/tex] has a p-value of 0.2981.
Hence:
P(x < 0.29) = 0.2981.
