Answer:
<u>84 students </u>
Step-by-step explanation:
See the attached table
As shown there are 20 students from Math club, 7 of them would like to choose calculators.
so, the probability of students who choose calculators = 7/20
If there are 240 students in the Math club
So, the number of students expected to choose calculators = 240 * 7/20
<u>So, the number of students = 84 students </u>
Answer:
I'd say go to Wikipedia and look it up. It is something that cannot be summarized into just a few words.
Step-by-step explanation:
74 units would be your answer for the length segment
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%
