Answer:
193.2
Step-by-step explanation:
To solve the triangle:
5.2 × 6= 31.2
You would normally find half of that since it's a triangle but there are two triangles, so each would equal half of 31.2 but if you add both halves that just equals 31.2.
Square one:
9 × 6= 54
All three squares are equal since they have the same measurements.
54 + 54 + 54= 162
162 + 31.2= 193.2
Find the mean ( average):
105 + 104 + 110 + 112 + 114 + 106 + 108 +109 = 868
Mean = 868 / 8 = 108.5
Standard deviation:
108.5 - 105 = 3.5, 3.5^2 = 12.25
108.5 - 104 = 4, 4^2 = 16
110 - 108.5 = 1.5, 1.5^2 = 2.25
112 - 108.5 = 3.5, 3.5^2 = 12.25
114 - 108.5 = 5.5, 5.5^2 = 30.25
108.5 - 106 = 2.5, 2.5^2 = 6.25
108.5 - 108 = 0.5, 0.5^2 = 0.25
109 - 108.5 = 0.5, 0.5^2 = 0.25
12.25 + 16 +2.25 + 12.25 + 30.25 +6.25+0.25+0.25 = 79.75
79.75/8 = 9.96875, SQRT(9.96875) = 3.1573
Standard Deviation = 3.1573
108.8 +/- 1.96 *(3.1573/sqrt(8) = 110.687 and 106.312
110.687 - 108.5 = 2.19
108.5 - 106.312 = 2.19
Margin of error = +/- 2.19
Answer:
B- $38.00
Step-by-step explanation:
Since there are two adults, you would multiply the cost of adults by number of adults. in this case that would be $10.75 x 2= $21.50. do the same for the kids and you will get $5.50 x 3 = $16.50. add 16.50 and 21.50 and you will get $38.00 which is your answer
hope this helped :D
Answer:
The correct option for the answer is C.) $3.29 / $2.96
Step-by-step explanation:
i) national average for a gallon of gas = $2.74
ii) for transportation New York is 1.2 times the National average
therefore one gallon of gas in New York will cost = 1.2 
$2.74 = $3.29
iii)for transportation Los Angeles is 1.08 times the National average
therefore one gallon of gas in New York will cost = 1.08 $2.74 = $2.96
Therefore you should expect to pay for gas in New York versus Los Angeles C.) $3.29 / $2.96
