Answer:
Floor 76
Step-by-step explanation:
4*6=number of floors in 60 second
100-24=floor 76
If a number is divisible by 5, 6, and 7,
<span>it's divisible by 5 x 6 x 7 = 210, the least </span>
<span>common multiple of the numbers. So her number </span>
<span>is a multiple of 210. The only 4-digit multiple </span>
<span>is 210 that starts 210 _ is 2100, so that's her number.</span>
Answer:
Step-by-step explanation:
Let x be the random variable representing the algebra test scores of the students. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 81.5
σ = 5.1
the probability that a student scores below 76.4 is expressed as
P(x ≤ 76.4)
For x = 76.4
z = (76.4 - 81.5)/5.1 = - 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
For x = 8
z = (8 - 6)/1 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.159
Therefore, the number of students that scored below 76.4 is
0.159 × 130 = 21 students
