The sides with the little stroke between the lines “B” and “E” are congruent to each other. Also, within the top of the triangles by the very tip of the triangle by “C” that are facing each other are congruent, and of course angle B and E are also congruent angles. I’ll show a picture so you can get a better understanding of what am exactly meaning. This is an AAS Triangle by the way. 1 side is congruent and 2 angles are congruent with this diagram. I really hope this answer and the picture helps!

9x^2 +x = 3^4 solve exponential equation
Answers
Answer:
Review both cases and pick the most appropriate answer
Step-by-step explanation:
First case where it's 9(x^2):
9x^2 + x = 3^4
9x^2 + x = 81
9x^2 + x - 81 = 0
x = b±√(b²-4ac) / 2a
x = 1±√(1²-4(9)(-81)) / 2(9)
x = 1±√(1+2916) / 18
x = 1±√(2917) / 18
x = 1+√(2917) / 18
x = 1-√(2917) / 18
Second case where it's (9x)^2:
(9x)^2 + x = 3^4
(9x)^2 + x = 81
81x^2 + x = 81
81x^2 + x - 81 = 0
x = b±√(b²-4ac) / 2a
x = 1±√(1²-4(81)(-81)) / 2(81)
x = 1±√(1+26244) / 162
x = 1±√(26245) / 162
x = 1+√(26245) / 162
x = 1-√(26245) / 162

The given number of observations is odd,
So the middle term is the median of the observation that is 81 (Ans)
Answer:
Your answer is 81.
Step-by-step explanation:
The median means the middle number, so you put the numbers in order from least to greatest, and the middle number is your median. However, if you have an even set of numbers, you chose the direct number in the middle of those 2 numbers for an example, if 6&7 were both your medians, it'd be 6.5

A rectangle has a perimeter of 36 centimeters. The length of the rectangle is five centimeters more than the width. What is the length of the rectangle?
Answers
Answer:
11.5 cm
Step-by-step explanation:
Set up a system of equations and simplify.
l = w + 5
2l + 2w = 36
Substitute w + 5 for l
2w + 10 + 2w = 36
4w + 10 = 36
4w = 26
w = 6.5
l = 6.5 + 5
l = 11.5

Answer:

Step-by-step explanation:
From the question we are told that:
Tangent [tex]AB=9[/tex]
Length [tex]AO=10[/tex]
Generally the angle at tangent [tex]\theta=90 \textdegree[/tex]
Therefore
Generally the equation for raduis R is mathematically given by

Find the value of each variable
Answers
Answer:
z = 77
y = 103
Step-by-step explanation:
The angle where 103 and z meet is supplementary, which means it is 180. Since we know one side is 103, we just have to subtract this value from 180 to find the other side, 77.
The total angle measure of a trapezoid is 360. Since we have all the values now except for one, we can simply add them all together: 95 + 77 + 85 = 257. Then, subtract this number, 257, from 360, to get the final angle measure as 103.
Hope this helped.

On a standardized exam, the scores are normally distributed with a mean of 350 and
a standard deviation of 40. Find the Z-score of a person who scored 346 on the exam.
Answers
Answer:
[tex]\boxed {\boxed {\sf z= -0.1}}[/tex]
Step-by-step explanation:
A z-score helps describe the relationship between a value and the mean of a group of values. Basically, it tells us how many standard deviations away from the mean a value is. The formula is:
[tex]z= \frac{x- \mu}{\sigma}[/tex]
where x is the value, μ is the mean, and σ is the standard deviation.
For this standardized exam, the mean is 350 and the standard deviation is 40. We want to find the z-score for a value of 346.
x= 346 μ= 350 σ= 40
Substitute the values into the formula.
[tex]z= \frac{ 346-350}{40}[/tex]
Solve the numerator.
[tex]z- \frac{ -4}{40}[/tex]
Divide.
[tex]z= -0.1[/tex]
The z score is -0.1, so the person with a score of 346 on the exam was 0.1 standard deviations lower than the mean.
