Answer:
Yes
Step-by-step explanation:
It is a random sample of the green balls in a bag because it never states that he is doing it someone.
3 x 4(hours) = 12
60 - 12 = 48
At 4am the temperature was 48 degrees
We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.
To find the time it took, divide the distance by his speed:
325 miles / 65mph = 5 hours.
Ha. That looks alot like i-ready. (i-ready sucks butt.)
But the horror that is i-ready aside, your answer is the third one : The proportion of grandparents that feel safe entering their account information online is 0.32.
32% converted to a decimal is 0.32, and 68% converted to a decimal is 0.68. That would mean that the proportion for grandparents that feel safe doing so is 0.32, and the number of grandparents that don't feel safe doing so is 0.68.
