Answer:
The degrees of freedom for this sample are 27.
The sample size to get a margin of error equal or less than 0.3656 is n=4450.
Step-by-step explanation:
The degrees of freedom for calculating the value of t are:
With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.
The sample size to get a margin of error equal or less than 0.3656 can be calculated as:
C the value of m and b doesn't affect the sign of the x-int
m is the slope of the line and b is the y-int
Answer:
To find the mean , median and mode of the students.
Step-by-step explanation:
The students choose from the three definitions of average to find the mean, median or mode of the students’ height in the school.
Students develop a strategy, collect and record data, and analyse data to answer this question.
The key concepts are
Consolidating the terms mean, median and mode.
The students should find the median of the height for the school if they have collected the median result of each grade.
The volume of the prism:
V = L x W x H,
where L is the length, W the width and H the height.
We can find the volume of the entire figure by adding together the volumes of two smaller figures ( 2 prisms ).
The 1st one has dimensions: 2, 2, 7 and the 2nd has dimensions 2, 3, 8.
Answer:
B . ( 2 x 2 x 7 ) + ( 2 x 3 x 8 )
