The point-slope form:
We have the points (5, -3) and (-2, 9). Substitute:
Answer:
3
Step-by-step explanation:
Each of the lines lengths multiply by 3.
Step-by-step explanation:
You want the to find the value of k such that the y coordinate of the vertex is 0.
0=x2−6x+k
The x coordinate, h, of the vertex is found, using the following equation:
h=−b2a
h=−−62(1)=3
Evaluate at x = 3:
0=32−6(3)+k
k=9
Answer:
Probability of choosing number = 0.9192
Step-by-step explanation:
Given:
New mean = 87.8
Mean = 85
Standard deviation = 14
Number picked = 49
Find:
Probability of choosing number
Computation:
Probability of choosing number = [New mean - Mean] / [Standard deviation / √Number picked]
Probability of choosing number <= [(87.8-85)]/[(14/7)]
Probability of choosing number = 0.9192
Answer:
The bottom boxes should be $100, $150, $200, $250, $300. The top box should be 8.
Step-by-step explanation:
So, at time 0 you only pay the rental fee of $100 (no time has passed yet). At 1 hour, it is $100 plus the $50 per hour rental fee. At 2 hours, it would then be $100+$100=$200. At 3 hours, it is $100+$150=$250. And at 4 hours, it is $100+$200=$300. By 8 hours, your fee is $100+$400=$500.
