g Use the information below for questions 1 through 5. A San Francisco-based tech firm is able to keep 80% of its new employees after one year. Assume that the retention probability of each new employee is independent of other employees. Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
Answer:
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A San Francisco-based tech firm is able to keep 80% of its new employees after one year.
This means that [tex]p = 0.8[/tex]
Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
This is P(X = 2) when n = 2. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.8)^{2}.(0.2)^{0} = 0.64[/tex]
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year

The car they will be using uses 6.3 litre/100km and runs on 50 ppm
diesel which will cost them R17.82/litre. Determine their fuel cost in
cents per kilometre.
(5)
Answer:
[tex]Cost = 112.266[/tex] cent/km
Step-by-step explanation:
Given
[tex]Unit\ cost = R17.82/litre[/tex]
[tex]Rate = 6.3litre/100km[/tex]
Required
The fuel cost in [tex]cent\ per\ km[/tex]
This is calculated using:
[tex]Cost = Unit\ cost * Rate[/tex]
[tex]Cost = R17.82/litre * 6.3litre/100km[/tex]
[tex]Cost = R17.82 * 6.3/100km[/tex]
[tex]Cost = R1.12266/km[/tex]
Multiply by [tex]100[/tex] to get the cost in cents
[tex]Cost = 1.12266 * 100[/tex] cent/km
[tex]Cost = 112.266[/tex] cent/km

Outcome a b c d e f
X 0 0 1.4 1.4 2 3
Determine the probability mass function of X. Use the probability mass function to determine the following probabilities.
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
Answer:
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6 ;
0 ;
1/2 ;
0 ;
2/3 ;
1/2
Step-by-step explanation:
Each has the same probability ;
X ___ : 0 ___ 0 ___ 1.4 ____1.4 ___ 2 ___ 3
P(x) __ 1/6 __1/6 ___ 1/6 ___ 1/6 ___1/6 __ 1/6
Probability : required outcome / Total possible outcomes
X = 0
P(x = 0) = 1/6 + 1/6 = 2/6 = 1/3
X = 1.4
P(x = 1.4) = 1/6 + 1/6 = 2/6 = 1/3
X = 2
P(X) = 1/6
X = 3
P(x) = 1/6
Hence ;
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
A.)
P(X = 1.6) = 0
B.)
P(0.5 < X < 2.7) = p(x = 1.4) + p(x = 2)
P(0.5 < X < 2.7) = 1/3 + 1/6 = (2 + 1) / 6 = 3/6 = 1/2
C.)
P(X > 3) = 0
D.)
P(0 ≤ X < 2) = P(0) + P(1.4)
P(0) + P(1.4) = 1/3 + 1/3 = 2/3
E.)
P(X = 0 or X = 2) = 1/3 + 1/6 = (2 + 1)/6 = 3/6 = 1/2

Someone answer this question if you know the answer.
Answer: F. 1/2
Step-by-step explanation:
If you add all the bows together, you get 10. The question is asking the probability of just 1 bow. This means you have a 1/10 chance. If you simply that, you end up with 1/2.

what is the answer to 4t−t+2
Answer:
3t+2
Step-by-step explanation:
First, we focus on the part with the "t" variable. Then we subtract the values with variables which gets us 3t. Finally, we can't do anything with the +2, so our solution is 3t+2.

What kind of triangle is shown?
I’m sorry for the blurry picture but please help
Answer:
Right scalene
Step-by-step explanation:
Which equation shows a correct relation for triangle RSQ?
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

Answer:
x+y=5...i
x²-y²=5...ii
from i, x+y=5

the length of the Boston Marathon is about 26 miles. A mile is equal to 1.609 kilometers. How many kilometers does a runner cover if he or she completes in the race
Answer:
41.834
Step-by-step explanation:
The complete length of the boston marathon is 26 miles
A mile is 1.609 kilometers
Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows
= 26 × 1.609
= 41.834
Hence the runner needs to run 41.834 kilometers
