Answer:
288 in²
Step-by-step explanation:
The formula used to solve this question is :
Lateral Surface Area = s( P1 + P2)
Where s = slant height = 2 inches
P1 and P2 = Perimeter of the bases
Perimeter of base 1 = 4 × length of the end of the small square
4 × 17 inches = 68 inches
Perimeter of base 2 = 4 × length of the end of the large square
4 × 19 inches = 76 inches
Lateral Surface Area = 2 × (68 + 76)
= 2 × 144
= 288 in²
Answer:
119
Step-by-step explanation:
Angle C= 62
So you add 62 + 57 which gives you 119
All angles must add up to 180 so you subtract 119 from 180 which gives you 61
Since angle A is 61 and a straight line angle is 180 you subtract 61 from 180 to give you angle B
180 - 61 = 119
therefore your answer is 119
The correct answer would be a Right triangle
Answer:
The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
Of the 500 surveyed, 350 said they were going to vote for the Democratic incumbent.
This means that 
80% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.
48 + (2*13) / 110
PE(MD)(AS)
2 * 13 = 26
48 + 26 / 110
26 / 110 = 0.236..
Rounded = 0.24
48 + 0.24 = 48.24….
