Answer: the probability of a student being overdrawn by more than $18.75 is 0.674
Step-by-step explanation:
Since the bank overdrafts of ASU student accounts are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = bank overdraft of Asu students.
µ = mean
σ = standard deviation
From the information given,
µ = $21.22
σ = $5.49
We want to find the probability of a student being overdrawn by more than $18.75. It is expressed as
P(x > 18.75) = 1 - P(x ≤ 18.75)
For x = 18.75,
z = (18.75 - 21.22)/5.49 = - 0.45
Looking at the normal distribution table, the probability corresponding to the z score is 0.326
Therefore,
P(x > 18.75) = 1 - 0.326 = 0.674

Answer:
10 inches
Step-by-step explanation:
the question is asking how much water the pond is losing over 5 weeks the pond loses 2 inches each week so if were going over the time span of 5 weeks the equation would 2×5=10
The value of x in the geometric sequence is -3.
Option (A) is correct.
To find the value of x.
<h3>What is geometric progression?</h3>
A progression of numbers with a constant ratio between each number and the one before .A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. For example, the sequence 1, 2, 4, 8, 16, 32… is a geometric sequence with a common ratio of r = 2.
Given that:
The geometric sequence are x, 3, -1/3.......
Let x = a be the first term
3 = a*r = x *r , is second term
r is the common ratio,
r =3/x
- 1/3 = ar^2 = x r^2
substitute r, and solve for x:
-1/3 = x*3*3/x*x
cancel out the x term from numerator and denominator we have,
-1/3=9/x
By cross multiplication,
x=-9/3
By simplifies
x=-3
first term is x = -3
So, the value of x in the geometric sequence is -3.
