Answer:
A
Step-by-step explanation:
When a slope is undefined, it is always x = ?
The point (-5, -8) tells us that x = -5
Option A also has a point with x = -5
Answer: 0.75
Step-by-step explanation:
We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.
We now have a triangle with the values of:
x = 4
y =3
h^2= 4^2 + 3^2
h^2 = 16 + 9
h^2 = 25
h = 5
h = 5
Tangent = opposite/adjacent
= y/x
= 3/4
= 0.75
Answer:
18
Step-by-step explanation:
13.5 / 3 = 4.5
so 4 x 4.5 = 16 + 2 = 18
Answer:
0.00084
Step-by-step explanation:
We are given that
Mean,
square feet
Standard deviation, 
square feet
n=50
We have to find the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet.
Using the formula
Hence, the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet=0.00084
