Answer:
a) 8.23% probability that a piece of pottery will be finished within 95 minutes
b) 0.28% probability that it will take longer than 110 minutes.
Step-by-step explanation:
Normal distribution:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Two variables:
Means 
Standard deviations 
Sum:


In this question:

So


A) What is the probability that a piece of pottery will befinished within 95 minutes?
This is the pvalue of Z when X = 95.



has a pvalue of 0.0823
8.23% probability that a piece of pottery will befinished within 95 minutes.
B) What is the probability that it will take longer than 110 minutes?
This is 1 subtracted by the pvalue of Z when X = 110.



has a pvalue of 0.9972
1 - 0.9972 = 0.0028
0.28% probability that it will take longer than 110 minutes.
Hi there! :)
Answer:

To find the area of the shaded region, we will need to find the areas of both the rectangle and the circle:
Rectangle: A = l × w
A = 11 × 12
A = 132 cm²
Circle: A = πr² (Let π = 3.14)
A = π(2)²
A = 4π
A ≈12.56 cm²
Subtract the area of the circle from the area of the rectangle:
132 - 12.56 = 119.44 cm².
Answer:
Step-by-step explanation:
Ratio is an expression that shows the relationship between two items in terms of quantity. It shows how much of one item can be found in another.
Simon used 3 pears and 9 apples to make a fruit salad.
This is expressed in terms of quantity.
The ratio of the number of pears which simon used to the number of apples which simon used will be
Number of pears which simon used ÷ the number of apples which simon used.
The ratio is 3/9.
Simplifying further to its lowest term,
It becomes 1/3
This is done by dividing the numerator and denominator by 3
Answer:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle, of length l and height h, is given by:

The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet.
This means that 
Estimate of the area:
To use an "easy" multiplication, lets consider
. So

Cameron determines the area of the wall to be 1423.125 square feet.
Very far from the area of 153, which means that he made a confusion with the decimal places. Thus, the correct answer is:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
