There are 15 boys what are you asking the sentence is not complete
Answer:
Option d (7.84 or less) is the right alternative.
Step-by-step explanation:
Given:
Random sample,
The level of significance,
= 0.95
or,
hence,
The margin of error will be:
⇒
By putting the values, we get
a test to see if it is a function is a vertical line test, if you draw a straight line and the line intersects at 2 points, it is not a function.
in this case, (-2,-2) is an open hole, which means the value where it is placed is just around that value so not exact.
the vertical line test would work if it was a closed hole, and one or both points (-2,3) and (-2,-2) would have to be removed.
the mistake that deshawn made was that he mixed up the vertical line test with horizontal instead and has deduced that since a horizontal line has intercepted both points, they must be removed.
this graph is, in fact, a function since the open hole is not exactly under (-2,3)
Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
