What are the answer options?
Answer:
C
Step-by-step explanation:
Given
A = 
Substitute the given values with h = a, then
16.5 = 
( multiply both sides by 2 )
33 = a(a + 8) ← distribute
33 = a² + 8a ( subtract 33 from both sides )
0 = a² + 8a - 33 ← in standard form
0 = (a + 11)(a - 3) ← in factored form
Equate each factor to zero and solve for a
a + 11 = 0 ⇒ a = - 11
a - 3 = 0 ⇒ a = 3
However, a > 0 thus a = 3
Hence the height is 3 feet
Answer:
238.2905
Step-by-step explanation:
you find out how many liters are in a gallon. then you divide 25.05 by the numbers you get when you find out how many liters are in a gallon. then you multiply 36.05 and the numbers you get when you divide 25.05 and the numbers of liters in a gallon.
Answer:
The actual height is 4.896
m
<em></em>
Step-by-step explanation:
Given
Required
Determine the actual height in metres
Represent the actual height with x.
So, the ratio of Scale Height to Actual Height as:
To calculate x, both ratios must be equal
Convert to fraction
Cross Multiply
Convert mm to metres
<em>The actual height is 4.896
m</em>
A mean is an arithmetic average of a set of observations. The mean number of visits the students made to the library in the last month is 2.32 visits.
<h3>What is Mean?</h3>
A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
For the given frequency table, the sum of the mean and the total number of values can be written as,
Sum = (0×284) + (1×218) + (2×76) + (3×64) + (4×42) + (5×320) = 2330
Total number of values = 284 + 218 + 76 + 64 + 42 + 320 = 1004
The mean for the table can be written as,
Mean = sum/ Total number of values = 2330/1004 = 2.32
Hence, the mean number of visits the students made to the library in the last month is 2.32 visits.
