Answer: c)1 solution
y=3x+2
y=4+2x
put the value of either y in another
3x+2 =4+2x
x=2
Answer:
7 units
Step-by-step explanation:
The distance between the points (2,−3) and (−5,−3) is 7 units.
Answer:
The number of student increased each year by 986.58.
Step-by-step explanation:
Given : In 2002, there were 972 students enrolled at Oakview High School.
To find : The number of students has increased by 1.5% each year ?
Solution :
Using the exponential growth function,

Here,
is the initial population
r=1.5%=0.015 is the rate
t=1 time



i.e. the number of student increased each year by 986.58.
Yes it is C if you do the math and simplify it that is what you’ll get
<u>Supposing 60 out of 100 scores are passing scores</u>, the 95% confidence interval for the proportion of all scores that are passing is (0.5, 0.7).
- The lower limit is 0.5.
- The upper limit is 0.7.
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 z-score that has a p-value of
.
60 out of 100 scores are passing scores, hence 
95% confidence level
So
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of all scores that are passing is (0.5, 0.7).
- The lower limit is 0.5.
- The upper limit is 0.7.
