It’s 7 1/2 because 4x3 gives you the length of the bigger rectangle so, you multiply 2 1/2x3 and get 7 1/2 :)
Its D . Subtraction property of equation
Let me show you why
p+5-8
Subtract 5 from both sides
p+5-5=-8-5
p=-13
So , yeah its D
Answer: Answer is C, Associative and Distributive
Step-by-step explanation:
On step one to step two it shows that llz is added to 6z (Both have Z) and from step 2 to 3, 5 is distributed (Multiplied) by 17z which equals 85z and also Distributed (Multiplied) by 29 which gives you 145. Which makes final equation... 85z + 145
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.
