V = PI x r^2 x H
1348.79 = 3.14 x 5.5^2 x H
1348.79 = 94.985 x h
h = 1348.79 / 94.985
h = 14.2 cm ( round answer if needed)
Answer:
(1,4)
Step-by-step explanation:
Which ordered pair is a solution of the equation? y = 7 x − 3
a. (1,4) b. (-1,-4) c. both d. neither
Solution
y=7x-3
Solve by trying each ordered pair
a. (1,4)
x=1, y=4
Substituting the value of x and y into the equation
y=7x-3
4=7(1)-3
4=7-3
4=4
This is a true statement
b. (-1,-4)
x=-1, y=-4
Substitute the value into the equation
y=7x-3
-4=7(-1)-3
-4= -7-3
-4= -11
This is not a true statement
This true statement is when x=1 and y=4
So, the ordered pair (1, 4) is the solution
Answer:
$1912.50
Step-by-step explanation:
5.5% of $1500 is 82.50
so 82.50×5(years)
=412.5 + 1500
=1912.50
Answer:
a) The average of compy heights is 33.5 cm
b) The 68.3 % of all compy heights are in the interval:
(30.94,36.06)
Step-by-step explanation:
a) Meaning of the mean
The mean is a number expressing the central or typical value in a set of data.
The average of compy heights is 33.5 cm. If the select one height randomly its height will be in average 33.5 cm
b) Meaning of standard deviation
The standard deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.
The 68.3 % of all compy heights are in the interval
(33.5cm - 2.56cm, 33.5cm + 2.56cm) = (30.94,36.06)
It means that the 68.3 % of all data is in the interval:
(μ - δ, μ +δ)
Where: μ is the mean
δ is the standard deviation
