Answer:The required interval is (0.196, 0.030).
Step-by-step explanation:
Since we have given that
n = 432
x = 108
So,
at 99% level of confidence, z = 2.576
So, Margin of error would be
So, margin of error = 0.0536
Now, confidence interval would be
Hence, the required interval is (0.196, 0.030).
If AB||CD and AD||BC,
then,
two adjacent pair of angles forms a linear pair.
which means,
Angle B+Angle C = 180°
3x-9 + 39 = 180°
3x+30 = 180
3x = 150
x = 50°
Value of x is 50°.

I think the answer is Y=-7/4+6
Answer:
The predicted number of customers for APP in 2022 is of 1.37 million, and of BPP is of 2.59 million.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
In which is the initial value and r is the rate of change.
11% of a city's population switches from phone service provider APP to phone service provider BPP each year, and about 5% of the populaton switches from BPP to APP each year.
This means that each year, the BPP amount increases by 11 - 5 = 6%, and the APP decreases by 6%. So the equations are:
BPP:
APP:
In 2018, there were 1.75 million customers of APP and 2.05 million customers of BPP.
This means that
Thus
Find the predicted number of customers for each provider in 2022.
2022 - 2018 = 4, so we have to find A(4) and B(4).
The predicted number of customers for APP in 2022 is of 1.37 million, and of BPP is of 2.59 million.
