Answer:
37.7
Explanation:
Just look at the number behind it if its a 5 or above it rounds up if not it stays the same and the ret of the numbers are zeros
Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
Step-by-step explanation:
(-1,-1) (0,3)
3- -1 / 0 - -1 = 4/1 = 4
slope is 4
Explanation:
AB=7
AC=9
You are looking for R
7+9=16
So R is 16
