Answer:

Step-by-step explanation:
Area of a rectangle is simply length times width
{
} * x would be the area
That can be simplified to

Which can be further simplified to

<span>If you want to
convert 1.4 into a fraction, you can do it like this:
<span>
1 <span>equals to </span>1/1 <span>and </span>0.4 <span>equals to </span>4/10 <span>which simplifies to </span>2/5.
<span>The result is </span>1 2/5.
If you want to write the ratio of 1.4/7 in the simplest form, you can do this using the following steps:
1.4/7 = 1 2/5 / 7 = 7/5 / 7 = 7/5 * 1/7 = 1/5 = 0.2
The correct result would be 1/5.</span></span>

Answer:
The probability that the average of the scores of all 400 students exceeds 19.0 is larger than the probability that a single student has a score exceeding 19.0
Step-by-step explanation:
Xi~N(18.6, 6.0), n=400, Yi~Ber(p); Z~N(0, 1);


P(Xi≥19.0)=0.473

p=0.473
Yi~Ber(0.473)

Based on the Central Limit Theorem:

Then:


Based on the Central Limit Theorem:


Then:
the probability that the average of the scores of all 400 students exceeds 19.0 is larger than the probability that a single student has a score exceeding 19.0
