Answer:
17/3 = 68/12
Step-by-step explanation:
17/3 =? 68/12
Get a common denominator of 12
17/3 * 4/4
68/12
They are equal so this is true
Answer:
The store can be 90% confident that the interval from 0.293 to 0.355 captures the proportion of all customers of this store who have moved in the past 5 years.
Step-by-step explanation:
The confidence interval provides a range of values (lower and upper bound) based on a certain confidence level at which the true proportion or mean value of a given sample mean or proportion exists. In the scenario above, the confidence level is 90% and the confidence interval is 0.293 to 0.355. Hence, we can be 90% confident that the true proportion of all customers of the store who have moved within the last five years exists within this interval.
the answer would (d) graph D
#2 Is Complementary because angle 1 and 2 are equal to 90 degrees
#4 Is Adjacent. That mean front he middle point/vertex both angles are on the same side and don’t over lap.
To finish the rest i have some notes.
Answer:
Given - (a-b)²=7
(a²+b²) =29
To find - ab
Solution -
( a- b) ^2 = 7
(a^2 + b^2) = 29
Expanding the bracket by using identity
a^2 + b^2 -2ab = 7
29 - 2ab = 7 (given a^2 + b^2 = 29 )
-2ab = 7 -29
-2ab = (-22)
ab = (-22) /(-2)
ab = 11
