Answer:
b= 5/4 or 1 1/4
Step-by-step explanation:
First I will make 1 3/4 into an improper fraction
1/2 + b = 7/4
Then I will make the fractions have common denominators
2/4 + b = 7/4
I subtract 2/4 from 7/4
b= 5/4
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,
= 
r = 0.75 cm
From the formula,
= ( 2 × × 0.75 × 5 ) + ( 2 × × 
)
= ( 7.5 ) + ( 1.125 )
A = 8.625
Result:
The surface area of cylinder is 8.625 , if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Answer:
Mean = $229.32
Median = $231.15
Mode = $268.4
Step-by-step explanation:
Mean = the average.
The average is the sum of variables divided by the number of variables.
x = each variable
N = number of variables = 11
Average = (Σx)/N = (236.09 + 204.43 + 253.82 + 268.4 + 231.15 + 205.7 + 262.18 + 162.77 + 268.4 + 224.45 + 205.17)/11
Mean = 2522.56/11 = $229.32
b) Median is the value that falls at the middle of the data set if all the variables are arranged in ascending or descending order.
So, to find the Median, we first arrange the variables in ascending order.
162.77
204.43
205.17
205.70
224.45
231.15
236.09
253.82
262.18
268.4
268.4
Since there are 11 variables, the Median is the number that falls at the middle of the distribution, that is, at the sixth position.
Median = $231.15
c) Mode is the number that appears the most in a distribution.
In this distribution, only 268.4 appears more than once.
Hence, the more is $268.4

Answer: Look below
Step-by-step explanation:
1(10x-6y)=-16
3(5x+2y)=66
10x-6y=-16
15x+6y=66
-25x=50
x=-2
