Answer:
27.19% probability that a female driver was involved in an accident
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
74,250 car accidents. Of those, in 20,187, the driver was a female.
Based on this, what is the probability that a female driver was involved in an accident?
p = 20187/74250 = 0.2719
27.19% probability that a female driver was involved in an accident
NightowlIt can be proven that between any two real numbers there exists a rational number. Therefore there exists a rational number r such that
<span>7.7+<span>2–√</span><r<7.9+<span>2–√</span></span>By calculator we can find a rational number r that satisfies these condition, I choose 9.2. Now subtract square root 2.<span>7.7<9.2−<span>2–√</span><7.9
</span>so the answer is between 7.7 and 7.9
rational number : 7.8
<span>irrational number : 9.2 - √2</span>
Answer:
3/4
Step-by-step explanation:
2/5+1/4+1/10=8/20+5/20+2/20=（8+5+2）/20=15/20=3/4
