Answer:
x = 40
Step-by-step explanation:
So a triangle is <u>180 degrees</u>
and thats a right triangle = 90 degrees
you have three corners: 90, 50 & x
90 + 50 + x = 180
140 + x = 180
subtract 140 from both sides
x = 40
hope this helps

Answer: The answer is option C
Step-by-step explanation:
<span>Congruent triangles are
triangles with the same sides and the same measure of angles. You are given
triangle DEF which is similar to triangle FGH. From the figure, side FH is
larger than side DF. So the statement of them being congruent cancels out. Triangle
DEF is smaller in size than triangle FGH. So they are not congruent. The slope
is defined as the rise over run. Side DF has the same slope as side FH. Sides DE
and FE are proportional to sides FG and HG. Only C and D is correct.

Answer:
10.03% probability of getting a cup weighing more than 8.64oz
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
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:
![\mu = 8, \sigma = 0.5](https://tex.z-dn.net/?f=%5Cmu%20%3D%208%2C%20%5Csigma%20%3D%200.5)
What is the probability of getting a cup weighing more than 8.64oz
This is the 1 subtracted by the pvalue of Z when X = 8.64. So
![Z = 1.28](https://tex.z-dn.net/?f=Z%20%3D%201.28)
has a pvalue of 0.8997
1 - 0.8997 = 0.1003
10.03% probability of getting a cup weighing more than 8.64oz
