if angle 3 and angle 4 are corresponding angles, then their vertical angles are also corresponding angles
always sometimes or never
Answers
Explanation:
Drawing out a diagram usually helps with these types of problem. See the diagram below.
We have angle 3 and angle 4 as corresponding angles (since they are both in the north east corner of each four-corner configuration). Angle 1 = angle 3 is one pair of vertical angles and angle 2 = angle 4 is another pair of vertical angles. We see that angles 1 and 2 are corresponding angles in the south west corners of each four-corner configuration. That's why the original statement is always true.

Step-by-step explanation:
Shortest side = [tex]\frac{1}{4}x[/tex]
Other side = [tex]\frac{3}{4}x[/tex]
Longest side = [tex]x[/tex]
[tex]24 = x + \frac{1}{4}x + \frac{3}{4}x\\24 = 2x\\12 = x[/tex]

Answer:
The Availability of tablets A,B and C are equal
Step-by-step explanation:
Computation for Which tablet has better Availability
Using this formula
Availability of Tablet=MTBF/ ( MTBF + MTTR)
Where,
MTBF represent Mean Time Between Failures
MTTR represent Mean Time To Repair
Let plug in the formula
Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)
Availability of Tablet A= 0.999
Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )
Availability of Tablet B= 0.999
Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)
Availability of Tablet C= 0.999
Based on the above calculation the Availability of all the 3 tablets are equal
Therefore the Availability of tablets A,B and C are equal.

Baseball - Part A
Rodney played in a baseball tournament.
During the first game, Rodney attempted to hit the ball 6 times, but only hit the ball 4 times.
During the second game. Rodney attempted to hit the ball 2 more times than the first game,
and hit the ball a total of 4 times.
In the first game, what is the ratio of Rodney's actual hits to Rodney's attempts to hit the ball?
(1 Point)
Answers
Answer:
8:8 or 1:1
Step-by-step explanation:
You need to add 6 and 2 together because those are the two numbers of times Rodney attempted to hit the ball. You should get 8. You also, need to add 4 and 4 together because those are the times Rodney actually hit the ball. You should also get 8. To get the ratio you need to compare the two outcomes and put them into this format: 8:8. But since they're both the same number, that means you can simplify it. Just divide them both by 8 to get 1:1. I hope this helps, Brandon!

BC = 1.7
Step-by-step explanation:
Since, cosine of any angle (except right angle) represents the ratio of base length and hypotenuse.
Cosθ = [tex]\frac{\text{Base}}{\text{Hypotenuse}}[/tex]
From the given right triangle ΔACB,
[tex]\text{Cos}(\angle B) = \frac{\text{Base}}{\text{Hypotenuse}}[/tex]
[tex]=\frac{BC}{AB}[/tex]
Cos(70°) [tex]=\frac{BC}{5}[/tex]
BC = 5Cos(70°)

Answers
112 employees work full time.
Explanation:
To approach this problem, we can first find the number of employees who work part time and subtract that number from the number of employees who work full time.
1) To find the number of part time employees, we multiply 0.72 by 400.
0.72*400
=288
2) Now, we subtract 288 from 400.

z=1.34 for the following null and alternative hypotheses:
0:=50
HA:μ>50
The p - value is
Answers
Look at a z table and look up z = 1.34.
The number associated with z = 1.34 is 0.9099
The p value is that value subtracted from 1.
P value = 1 − 0.9099 = 0. 0901
The p - value for the test statistic should be considered as the 0.0901.
Calculation of the p-value:Since there is null and alternative hypotheses
so here we look at the z table and then the value should be 1.34
So, the value of z in 1.34 should be 0.9099
So, here the p-value should be
= 1 - 0.9099
= 0.0901
hence, The p - value for the test statistic should be considered as the 0.0901.
