Answer: (1, 0) or 1
Step-by-step explanation:
Since it is parallel to y=2x-7 that means it has the same slope but a different y-intercept. Let's use b for the unknown value
6=2(4)+b
6=8+b
6-8=8+b-8
-2=b
Now we know the equation for the line is y=2x-2
Since we are looking for the x-intercept y will be 0 and we can sub that in to solve
The x-intercept is 1
Answer:
A
Step-by-step explanation:
find there common denominator which is 40
multiply 3 by 8 and 7 by 5 to get 24 and 35
35-24=11
11/40
18-7=11
11 11/40
Answer:
A sample size of 6755 or higher would be appropriate.
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 .
The margin of error M is given by:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
52% of Independents in the sample opposed the public option.
This means that
If we wanted to estimate this number to within 1% with 90% confidence, what would be an appropriate sample size?
Sample size of size n or higher when . So
A sample size of 6755 or higher would be appropriate.
Answer:1.047
Step-by-step explanation:calculate the length of an arc using the formula:
s=θ/360×2×π×r
If the central angle is 20
and a circle has a radius of 3, then the length of the intercepted arc is equal to:
s=20/360×2×π×3
Taking π=3.14:
s=20/360×2×3.14×3≈1.047
