Answer:
The solution is the interval (-∞,5]
Step-by-step explanation:
we have
The solution is the interval -----> (-∞,5]
All real numbers less than or equal to 5
In a number line the solution is the shaded area at left of x=5 (close circle)
see the attached figure
Answer:
The probability that you get zero questions correct is 0.4096
The probability that you get one questions correct is 0.4096
The probability that you get three questions correct is 0.0256
Step-by-step explanation:
These probability can be describe with a Binomial Distribution. These distribution can be used when we have n identical and independent situations in which there is a probability p or probability of success and a probability q or probability of fail. Additionally q is equal to 1 - p. The probability of x for a situation in which we can apply binomial distribution is:
Where x is the variable that says the number of success in the n situations
And nCx is calculate as:
From the question we can identify that:
- n is equal to 4 multiple choice question
- p is 1/5 or 0.2, the probability of get one question correct
- q is 4/5 or 0.8, the probability of get one question incorrect
Then the probability of get zero questions correct of 4 questions is:
The probability of get one question correct of 4 questions is:
The probability of get three questions correct of 4 questions is:
Answer:
2,586
Step-by-step explanation:
Add 1000+1000
2000
Since its 999 not 1000 subtract 1
1999
Now add 1 and subtract 1 from 587
Then add 2000 with 586
2,586
Answer:
Kanye run faster.
Step-by-step explanation:
Given that,
Time = 1 min = 60 sec
Suppose, we find the speed of kanye and Jay.
According to number line,
Kanye covers the -160m distance and Jay covers the 140 m distance.
Negative sign shows the opposite direction.
We need to calculate the speed of Kanye
Using formula of speed
Where, v = speed
d = distance
t = time
Put the value into the formula
We need to calculate the speed of Kanye
Using formula of speed
Put the value into the formula
The speed of kanye is more than jay.
Hence, Kanye run faster.
3/5 cause you get the lowest common denominator
