Answer:
8+18W
Step-by-step explanation:
distribute the 2 into the parentheses. 2×4 is 8 and 2×8 is 18.
Answer:
a) mean = 0.2
variance = 0.0391
standard deviation = 0.198
b) The average hurricane is aprox. category 2.* (B)
Step-by-step explanation:
In order to find the mean, variance, and standard deviation, let us for a table for the data:
level x
1 0.411
2 0.278
3 0.221
4 0.080
5 0.010
Calculating the mean ()
∴Mean = 0.2
level x
1 0.411 0.211 0.0445
2 0.278 0.078 0.0608
3 0.221 0.021 0.000441
4 0.080 -0.12 0.0144
5 0.010 -0.19 0.0361
standard deviation = √(variance)
Standard deviation = √(0.0391)
Standard deviation = 0.198
b) the average hurricane is aprox. category 2 (B)
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Vertical compression
Answer:
$21.40
Step-by-step explanation:
List price = $19.95
Sales Tax Rate = 7.25%
Total sales tax = 19.95 x 7.25/100 = $ 1.45
Total cost = 19.95 + 1.45 = $21.40
