Answer:
48 ft cubed or 576 in cubed
Step-by-step explanation:
The volume of the water is 2304 in cubed. you multiply 12 in by 24 in by 8 in.
the rock makes the water go up 2 in. You then multiply 12 in by 24 in by 10 in. This will equal 2880 in cubed.
2880-2304=
576 in. cubed or 48 ft. cubed
<span>how many services you had if you were charged $115?
set f(x) to 115 and solve for x:
f(x) = 15x + 25
115 = 15x + 25
90 = 15x
6 = x</span>
Answer: Predicted level of social skill will be 46
Step-by-step explanation:
For a linear regression; the general equation is in the form;
y = mx + c
Where is the predicted value or variable
m = slope or gradient (regression coefficient )
c = intercept which is constant (this is where the line of best for crosses the y-axis.
y = predicted value
x = independent variable
Given the following:
Regression coefficient (m)= 3
Regression constant (c)= 16
Score(x) = 10 (independent variable)
From:
y = mx + c
y = 3(10) + 16
y = 30 + 16
y = 46
Predicted level of social skill will be 46
The histogram shows the heights in meters of trees in a certain section of a park.
How many trees are less than 20 meters tall?
Answer: From the given histogram, we clearly see:
There is 1 tree with height less than 8 meters
There are 1 + 2 = 3 trees with height less than 12 meters
There are 3 + 2 = 5 trees with height less than 16 meters
There are 5 + 4 =9 trees with height less than 20 meters.
Therefore, the correct option is B. 9
