To do this divide set miles (264) by hours (5.5) to give you 48. Then multiply you mph (48) by 7. So in seven hours, Shawna can drive 336 miles.
In other words, you know that 50 percent of a number is 34 and you want to know what that initial number is.
To solve this problem you multiply 34 by 100 and then divide the total by 50 as follows:
(34 x 100) / 50
When we put that into our calculator, we get the following answer:
68
Answer:
Option D. 1
Option E. 1/2
Step-by-step explanation:
we know that
Looking at the graph
The domain is the interval ----> [-1,1]

The domain is all real numbers greater than or equal to -1 and less than or equal to 1
The range is the interval ----> [0,1]

The range is all real numbers greater than or equal to 0 and less than or equal to 1
therefore
The values that are in the range are
1 and 1/2
Answer:
Step-by-step explanation:
Let X be the length of pregnancy.
X is N(268, 15)
a) Prob of pregnancy lasting 307 days or longer
= P(X>307) = 
=0.5-0.4953
=0.0047
b) Lowest 2% is 2nd percentile
Z=-2.55
X score = 268-2.55(15)
= 229.75 days
If length of days >230 days then it is not premature.
Yes, sqrt of 1815, cannot be rationalized
