Answer:15
Step-by-step explanation:The formula for volume of a square pyramid is A^2 * h/3 with A being base side length and h being height, so just plug in 3 for a and 5 for h, getting you (3)^2 * 5/3, then 9* (5/3) then 45/3 then 15
Answer:
=(4x+10)x3/5
Step-by-step explanation:
3(4x+10/2+3)
=3x4x+10/2+3
=3x4x+10/5
=(4x+10)x3/5
Answer:
The average life of the mice that are placed on this diet is less than 40 months.
Step-by-step explanation:
Consider the provided information.
When 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ < 40.
The null and alternative hypothesis are:
64 mice that are placed on this diet have an average life is 38 months with a standard deviation of 5.8 months.
Therefore,
Use the formula:
Substitute the respective values in the above formula.
Now using the table
The p value is smaller than 0.05 so reject the null hypothesis.
Therefore, the average life of the mice that are placed on this diet is less than 40 months.
Answer:
Step-by-step explanation:
<u>Method 1:</u>
$300 on school supplies
1/10 on notebooks
As you're finding how much is left:
10/10-1/10=9/10
Convert 9/10 into a decimal
9/10=0.9
300*0.9=$270
OR
<u>Method 2: </u>
1/10=0.1
300*0.1=$30
Take away 30 from $300
$300-30=$270
By using either method, You would still have $270 left.
How this helps!!!
Have a nice day :)
