) At a certain college, students are allowed to choose between online and in-person learning. 70% of the students choose online learning and 30% choose to come to campus for in-person instruction. Assume that the probability that a person studying online will contract the coronavirus is .02 and the probability that a person attending class in-person contracts the virus is .35 . (a) What is the probability that a person attending this college (either online or in-person) will contract the virus
Answers
Answer:
Probability = 0.119
Step-by-step explanation:
P (Coronavirus) = P(Person online & corona) or P(Person offline & corona)
(0.70 x 0.02) + (0.30 x 0.35)
0.014 + 0.105
0.119

Explanation:
On the first pass, you know ...
- g = 80° . . . vertical angles
- I = 110° . . . vertical angles
- m = 20° . . . alternate interior angles (WX║ZY)
Then on the second pass, you can figure ...
- f = h = 180° -80° = 100° . . . linear angles
- j = k = 180° -110° = 70° . . . linear angles
- b = n = 180° -110° -m = 50° . . . sum of angles of a triangle
And the remaining angles can be determined using external angle and sum-of-angle relationships.
- a = o = h -70° = 30°
- c = 80° -b = 30°
- d = 360° -80° -20° -I = 150°
- L = c - m = 10° . . . c and L+m are alternate interior angles
- e = L +70° or 110° - o = 80°

Explanation:
1) Question: divide 8x⁴+2x³-7x²+3x-2 by 4x² - x + 1
2) First term of the quotient
8x⁴ + 2x³ - 7x² + 3x - 2 | 4x² - x + 1

Hello there!
35/100 watch more then 10 hours a week
3000 is 30 times greater than 100 so we can simply multiply 35/100 by 30.
35/100 x 30 = 1050/3000
Therefore, if the company had 3,000 subscribers, 1,050 subscribers would be watching more than 10 hours a week.

This is a division problem since we would need to divide in order to answer the question.
Divide the amount of rides she rode to the number of hours she was there.
Input the numbers below:
amount of rides she rode/number of hours there
14/7=2
At this rate, Ramona rode 2 rides per hour.
7÷14=0.5

Answer:
49 days
Step-by-step explanation:
The spread of the disease is modeled as
where n = number of infected people
t = time (in days)
When the number of infected people is 1400, the number of days t will be:
It will take 49 days for the number of infected people to reach 1400.
Final answer:
Given the function n=200 Square root t where n is the number of infected, and t is time, it will take 49 days for the number of infected people to reach 1400.
Explanation:
To find out how long it will take until the number of infected people reaches 1400, we are going to set n = 1400 (number of infected people) in the given equation, and then solve for t (time in days).
So, 1400 = 200 √t. Dividing both sides by 200, we get √t = 7. Then, squaring both sides give us t = 49 days. So, it will take 49 days for the number of infected people to reach 1400.
Given the function n=200 Square root t where n is the number of infected, and t is time, it will take 49 days for the number of infected people to reach 1400.
