Answer:
301 sandwiches were made with whole wheat bread
Oh my gosh I used to have that same workbook I HATED it. Anyways, the formular for volume is length x width x height, so for this rectangular prism you would multiply 4 2/5 x 10 x 3. Also it doesn’t matter which order you multiply because you should still have the same end result.
Hope this helps! If you need anymore answers from this book then ask me. My teacher made us do like 10 pages a day all school year.
Answer:
10x + 30 = 600
Step-by-step explanation:
Johnny gets $10 per week, which is $10x for x number of weeks.
He already has $30, so his money becomes 10x + 30.
His goal is to have $600, so our equation becomes 10x + 30 = 600
Answer:
4
5
Step-by-step explanation:
From the question we are told that
The percentage of hair dryers that are defective is p=2%
The sample size is
The random number is x = 219
The mean of this data set is evaluated as
substituting values
The standard deviation is evaluated as
substituting values
Since it is a one tail test the degree of freedom is
df = 0.5
So
Now applying normal approximation
substituting values
From the z-table
Considering Question 5
The random number is x = 90
The mean is
Where n = 100
and p = 0.85
So
The standard deviation is evaluated as
substituting values
Since it is a one tail test the degree of freedom is
df = 0.5
Now applying normal approximation
substituting values
From the z-table
