To solve this
problem, we will have to make use of the z statistic. The formula for the z
score is given as:
z = (x – u) / s
where,
x is the sample value = more than $10.00
u is the sample mean = $8.22
s is the standard deviation = $1.10
Substituting the values into the equation to solve for z:
<span>z = (10 – 8.22) /
1.10</span>
z = 1.78 / 1.10
z = 1.62
We then look for the p value using the standard
distribution tables at the specified z score value = 1.62. Since this is a
right tailed test, therefore the p value is:
p = 0.0526
or
p = 5.26%
<span>Therefore there is a 5.26% probability that a household
spent more than $10.00</span>
Answer: 3/16 of a pie.
Step-by-step explanation: To find the answer, we divide 3/4 by 4 to get 3/16. Thus, each person will get 3/16 of a pie.
Answer:
4. x = 7.5
5. x = 17.9
6. x = 18.4
Step-by-step explanation:
4. Cos(60) = x/15
x = 15*Cos(60)
x = 7.5
5. Tan(50) = x/15
x = 15*Tan(50)
x = 17.9
6. Cos(57) = 10/x
x = 10/Cos(57)
x = 18.4
Fam,
Take the average boundary of it. So it would be 8 * 4 = 32.
Thus, it must be less than 32 and most likely greater than 20 so its B!
I believe it is 1/6 but i'm not sure .
hope that helped
