Answer:
x = 3, y = 2
Step-by-step explanation:
Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.
- <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
- <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
- <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
- <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>
Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.
As a result, the letter C is the correct response.

Its A i just took the test
Step-by-step explanation:
The diagram where angles 1 and 2 form a linear pair is D. A horizontal line has 1 line extending from it. Angles 1 and 2 are formed.
<h3>What is a linear pair?</h3>
It should be noted that a linear pair simply means angles that are formed when two lines intersect each other at a single point.
In this case, when a horizontal line has 1 line extending from it. Angles 1 and 2 are formed. This depicts a linear pair
In conclusion, the correct option is D.

Answer:
Step-by-step explanation:
given that certain tubes manufactured by a company have a mean lifetime of 800 hours and a standard deviation of 60 hours.
Sample size n =16
Std error of sample mean = 
x bar follows N(800, 15)
the probability that a random sample of 16 tubes taken from the group will have a mean lifetime
(a) between 790 and 810 hours,
=
(b) less than 785 hours

, (c) more than 820 hours,

(d) between 770 and 830 hours
=
