Answer:
<u>The volume of the pyramid is 16 m³ (cubic meters)</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Length and width of the square pyramid = 4 m
Height of the square pyramid = 3 m
2. What is the volume of the square pyramid?
Let's use the formula of the volume of a pyramid:
Volume = (Length * Width * Height)/3
Volume = 4 * 4 * 3/3
Volume = 48/3 (Dividing by 3)
<u>Volume = 16 m³(cubic meters)</u>

Answer:
The answer would be -10
Step-by-step explanation:
(-2)+2*(-2)-10
4-4-10
-10
16 + h + 43 = 81
h + (16 + 43) = 81
h + 59 = 81
h + 59 - 59 = 81 - 59
h = 22
Answer:
Step-by-step explanation:
The mean SAT score is , we are going to call it \mu since it's the "true" mean
The standard deviation (we are going to call it ) is
Next they draw a random sample of n=70 students, and they got a mean score (denoted by ) of
The test then boils down to the question if the score of 613 obtained by the students in the sample is statistically bigger that the "true" mean of 600.
- So the Null Hypothesis
- The alternative would be then the opposite
The test statistic for this type of test takes the form
and this test statistic follows a normal distribution. This last part is quite important because it will tell us where to look for the critical value. The problem ask for a 0.05 significance level. Looking at the normal distribution table, the critical value that leaves .05% in the upper tail is 1.645.
With this we can then replace the values in the test statistic and compare it to the critical value of 1.645.
<h3>since 2.266>1.645 we can reject the null hypothesis.</h3>
