Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 degrees
so
70 + 35 + x = 180 add like terms
105 + x = 180 subtract 105 from both sides
x = 75
Answer:
a- the sum = 0.0031
b- the fly is 0.0013 grams heavier
Answer:
c = 20d + 15

c = 20d + 15
Answer:
The 95% confidence interval is 
.
Step-by-step explanation:
The information provided is:
The critical value for 95% confidence level is:
Compute the margin of error as follows:
Then the 95% confidence interval is:
Thus, the 95% confidence interval is .
5/6 + 1/3
To add both sides need the same denominator. To give he fractions a common denominator, multiply the second fraction (1/3) by 2.
5/6 + 2/6
Add the numerators
7/6
Change into mixed number
1 and 1/6
