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.
Additive Identity.
When a number (x) added to zero it will give the number itself as the result.
X + 0 = X
74 + 0 = 74
Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.
<h3>What is
speed?</h3>
Speed is the ratio of distance to time.
For Jada:
Speed = 2 miles / 12 minutes = 0.167 miles per minute
For Jada cousin:
Speed = 1 mile / 24 min = 0.0417 miles per minute.
Hence, in 15 minutes:
Jada distance = 15 min * 0.167 miles per minute = 2.5 miles
Jada cousin distance = 15 min * 0.167 miles per minute = 0.625 miles
In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.
