.5 as a fraction is 1/2 and .005 as a fraction is 5/1000. You need to find a common denominator. To get the 2 in 1/2 to 1000 you multiply by 500. You do the same to the numerator. So 1 x 500 = 500. So it would read 500/1000. Add these 2 fractions together to get 505/1000. Simplify to 101/200.
The formula is jus y= mx + b
M is the slope (rise over run)
And b is the y- intercept
Hope that helps
Answer with Step-by-step explanation:
Let speed of one car=x miles/h
Speed of second car=x+8 mi/h
Time,t=2 hours
Distance between two cars=208 miles
We have to find the average speed for each car for 2-hour trip.
Distance=
Distance traveled by one car=2x
Distance traveled by second car=2(x+8)
According to question





Speed of one car=48mph
Speed of second car=48+8=56mph
Answer:
, option D
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
.
From a random sample of 50 students, she found that 32 students read at least 1 book last month.
This means that 
90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Confidence interval:


So the correct answer is given by option D.
