Answer: 0.135
Step-by-step explanation:
if 54 % of internet users have a wireless connection then number of people that do nor have a wireless connection =46%.
Let A be the event that 54% of internet users have wireless connection.
Let B be the event that 25% of these users that have internet connection use twitter to share updates about themselves.
Hence, probability of A and B happening becomes:
P(AnB) = P(A) * P(B)
P(AnB) = 0.54 * 0.25
P(AnB) = 0.135
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
If the line is perpendicular, it will have a opposite reciprocal slope.
So, the slope will be -1/4.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
-6 = -1/4(12) + b
-6 = -3 + b
-3 = b
Plug in the slope and y intercept into y = mx + b
y = -1/4x - 3
So, the correct answer is D. y = -1/4x + 3
Answer:
1. her elevation at noon was 3 meters
2. (-2, 7)
3. (1, 0)
Step-by-step explanation:
1. when x = 0, it is noon, y = 3 when x is 7
2. when x = -2 it is 10 am because when x is 0, it is noon, or 12 pm, her elevation is 7 meters above sea level
3. when x is 1, it is 1 pm, and her elevation is 0 meters
30=12m
you divide both sides by 12
so 30/12 is 2.5
