Answer:
190 ft^2
Step-by-step explanation:
So first we need to find which equation we're using and since it's a rectangular prism we're going to use:
2Lw + 2wh + 2Lh
Now what we need to do is plug in the values
2*9*2 + 2*2*7 + 2*9*7
Now just multiply everything and then add it together.
36 + 28 + 126
Once you add everything together you get:
190
The question says to include the correct unit. It says that its feet, but we need to know if its feet squared (^2) or cubed (^3)
If it were area of the whole object, it would be cubed because it is all the area that the object takes up but since it's just the area of the surface it's going to be squared. Therefore, the answer is:
190 ft^2
Answer:
Cost of one glove pair is $ 8.50 and the cost of one hat is $6.50
Step-by-step explanation:
Let g represents the cost of one gloves pair
h represents the cost of one hat
Then
Cody brought two pairs of gloves and four hats for $43.00
This can be written as
2g + 4h = 43-------------------(1)
Tori bought two pairs of gloves and two hats for 30.00
This can be written as
2g + 2h = 30------------------(2)
Subtracting (2) from (1)
2g + 4h = 43
2g + 2h = 30
(-)
--------------------------
0g + 2h = 13
------------------------------------
2h =13
h = 13 / 2
h = 6.5---------------------(3)
Substituting (3) in (2)
2g + 2(6.5) = 30
2g + 13 = 30
2g = 17
g = 17 / 2
g = 8.5
So one hat is $6.50 and one pair of gloves is $8.50.

b) The relative frequency histogram as attached diagram.
As shown, the plot is skewed to the left.
c)
i) mean = 62.7
ii) median = 72
iii) Standard deviation = 24.87923
Step-by-step explanation:
a) The first approach is to sort the data in ascending or descending order. Next, we Identify the minimum grade and the maximum grade. We then list the stems based on the minimum and maximum. And we construct the stem and leaf diagram as show. The first digit represents the stem and the last digit represents the leaf.
As shown, all the grade are two digits value, with minimum as 06 and maximum as 98. In this case, the first stem is 0 and the last stem is 9.
Others (b & c) are just the usual calculations.
C. (0,2) if you plot these points correctly on a graph, the center is at 0,2. hope this helped.
