Answer:
.
Step-by-step explanation:
Two angles are supplements of one another if their sum is
.
Two angles are complements of one another if their sum is
.
Let
be the measure of the angle in question.
The supplement of this angle would be
.
The complement of this angle would be
.
According to the question:
.
Solve this equation for
:
.
Thus, this angle would measure should
.
The supplement of this angle would measure
. The complement of this angle would measure
.
Three times the complement of this angle would be
, which is indeed
greater than the supplement of this angle.
Answer:
24.7 feet
Step-by-step explanation:
This is a Pythagorean theorem question
The ladder is the hypotenuse or c
the distance from the wall is a leg or a
and the wall is the other leg or b
a² + b² = c²
a² + 17² = 30²
a² + 289 = 900
-289 -289
b² = 611
√ √
b = √611
b = 24.7 feet
Answer: 3.712 hours or more
Step-by-step explanation:
Let X be the random variable that denotes the time required to complete a product.
X is normally distributed.

Let x be the times it takes to complete a random unit in order to be in the top 10% (right tail) of the time distribution.
Then, 
![P(z>\dfrac{x-3.2}{\sigma})=0.10\ \ \ [z=\dfrac{x-\mu}{\sigma}]](https://tex.z-dn.net/?f=P%28z%3E%5Cdfrac%7Bx-3.2%7D%7B%5Csigma%7D%29%3D0.10%5C%20%5C%20%5C%20%5Bz%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5D)
As,
[By z-table]
Then,

So, it will take 3.712 hours or more to complete a random unit in order to be in the top 10% (right tail) of the time distribution.
First, plug in 448 for y:
448=7x+294
Secondly, subtract 294 from both sides to isolate x:
154=7x
Divide both sides by 7:
22=x
Refine:
x=22
The answer is D)22
