Answer:
99.7%
Step-by-step explanation:
Using the z score formula
z-score is z = (x-μ)/σ
where:
x = raw score
μ = population mean
σ = population standard deviation.
a) for x = raw score = 35
μ = population mean = 44
σ = population standard deviation =3
z = (35 - 44)/3
z = -9/3
z = -3
b) for x = raw score = 53
μ = population mean = 44
σ = population standard deviation =3
z = (53 - 44)/3
z = 9/3
z = 3
We would use the standard normal distribution table to find their probabilities
P(Z<=-3)=0.0013499
P(Z<=+3)=0.99865
So P(-3<=Z<=3)=0.99865 - 0.0013499 = 0.9973
Converting to percentage = 0.9973 × 100 = 99.73%
Therefore, the percentage of auto batteries of this brand that have a life of 35 to 53 months to one decimal place is 99.7%
QUESTION 10:
- The long edge of the paper is 11 inches long
- The frame is 4 long edges long
4 times 11 = 44 inches.
Now for the feet calculation!
- 1 foot = 12 inches
44 inches divided by 12 inches is 3 2/3 feet.
RESULT:
Cameron's poster frame is 44 inches long and 3 2/3 feet (OR 3.66666667 feet).
QUESTION 11:
- First, convert 3 yards into feet.
- 1 yard = 3 feet
- 3 yards = 9 feet
- 9 feet plus 2 feet = 11 feet.
- Converting feet into inches means multiplying the number of feet by 12 (since every foot has 12 inches)
-11 feet times 12 = 132 inches.
RESULT:
Use my explanation to determine that 3 yards and 2 feet = 132 inches.
Answer:
25x-25y
Step-by-step explanation:
The distributive property tells us how to solve expressions in the form of a(b + c).
So, a*b and a*c would be the answer.
25*x and 25*y
