Answer: A:60%
Step-by-step explanation:
Since the scores for a golf tournament are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = scores for the tournament.
µ = mean score
σ = standard deviation
From the information given,
µ = 210
σ = 80
We want to find the probability percent of golfers that scored less than Ella. It is expressed as
P(x < 230)
z = (230 - 210)/80 = 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.5987
Therefore, the percent of golfers that scored less than Ella is
0.5987 × 100 = 59.87
Approximately 60%
Answer:
the answer is 9271
Step-by-step explanation:
if 7300 is 73%, then you need to add 27% to get 100% which is 9271
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12
Square root of 1.6 is 1.265
8.2 —- 2.864
24—— 4.89
26—— 5.09
Hope this helped :)
Answer:
x >7
Step-by-step explanation:
There is an open circle at 7, which means it cannot equal 7. The line goes to the right
x >7
