To complete a task In 16 days a company needs 5 people 6 hours a day. How long will it take 8 people 4 hours a day, assuming the
1 answer:
8 people working 4 hours a day will take 15 days to complete the work.
S<u>tep-by-step explanation:</u>
The problem can be solved using chain rule
no of people no of hours no of days
5 6 16
8 4 ?
number of days decreases when the number of people increases from 5 to 8. The decrease of number of hours from 6 to 4 increases the number of days taken for the work to get completed.
8 people working 4 hours a day will take 15 days to complete the work.

Answer:
-36/7 or -5.14287
Step-by-step explanation:
so I would get rid of parentheses you do not need them
=
(because when two negative come before two numbers like -x-y they are being added but negative is present to the result of the sum, when one negative sign comes after a number and the other negative sign comes before a number, like x--y they are being added as well but negative is not present to the result of the sum)
-36/7=-5.1428
hope this helps!
Recall that a slope-intercept form of a linear equation is
Rearrange the given so that it follows that slope intercept form
The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).
Answer:
0.337 = 33.7% probability that one of the eight children has a food allergy.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either they have a food allergy, or they do not. The probability of a child having food allergy is independent of any other child. 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.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
7% of U.S. children 4 years of age or younger have a food allergy.
This means that
A day care program has capacity for 8 children in that age range.
This means that
What is the probability that one of the eight children has a food allergy?
This is P(X = 1).
0.337 = 33.7% probability that one of the eight children has a food allergy.
