Answer:
It is a ratio. Is it?
If so, I think the answer is 773 : 6
Answer:
72
Step-by-step explanation:
Consecutive even integers have a difference of 2 between them
let n be the first integer, then
n + 2, n + 4, n + 6 are the second, third and fourth, then
n + 2 + n + 6 = 76 ( sum of second and fourth )
2n + 8 = 76 ( subtract 8 from both sides )
2n = 68 ( divide both sides by 2 )
n = 34
Thus the 4 even integers are
34, 36, 38, 40
sum of first and third = 34 + 38 = 72
That is a direct division, if you are confused by the decimal point, lets get rid of it! We can get rid of the decimal point multiplying the upper and lower parts of the division by 10, lets do it:
<span>62.8 / 3
= 10*</span><span>62.8 / 10*3
= </span><span>628 / 30
we can try to reduce the fraction dividing by 2 the upper and lower parts:
= 314/15
and now we have to make the operation:
= 20.93</span>
Answer:
Yes; Since the confidence interval limits are both greater than 50%, we can reasonably conclude that more than half of all adults would take a ride in a fully self-driving car.
Step-by-step explanation:
From the question we are told that
The sample size is n = 500
The sample proportion is 
The 95% confidence interval is (0.5266, 0.6134)
Looking at the 95% confidence level interval we see that the sample proportion is within the interval and given that the confidence interval limits are both greater than 50%, we can reasonably conclude that more than half of all adults would take a ride in a fully self-driving car.
Answer:
-15 plus or minus the square root of 65 all over 4 (All over means fraction)
