A company has 500 employees, and 60% of them have children. Suppose that we randomly select 4 of these
employees.
Which of the following would find the probability that exactly 3 of the 4 employees selected have children?
Answers
The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula ⁴C₃(0.60)³(0.40)
What is a Binomial Distribution?
The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = ⁿCₓ pˣq⁽¹⁻ˣ⁾
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the total number of employees be = 500
Now , the probability of success of selecting employees having children is given by p = 0.60
So , the value of q = 1 - p
q = 1 - 0.60
q = 0.40
So , The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula
where,
P ( x ) = ⁿCₓ pˣq⁽¹⁻ˣ⁾
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Substituting the values in the equation , we get
P ( x ) = ⁴C₃(0.60)³(0.40)
On simplifying the equation , we get
P ( x ) = 4 x 0.246 x 0.4
P ( x ) = 0.3456
Therefore , the value of P ( x ) is 0.3456
Hence , The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula ⁴C₃(0.60)³(0.40)

tance by a motorbike How many km did he

Answers
Answer:
8 km by motorbike.
Step-by-step explanation:
The distance between itahari and Damak is 42 km.
Mr. Dhamala travelled 18.325 km by a bus / 15.675 km by a taxi and the remaining distance by a motorbike.
Let he covered x distance by motorbike. So,
Remaining distance = Total distance -(distance covered by bus + distance by taxi)
= 42 -(18.325 +15.675 )
= 42-34
= 8 km
So, he travelled 8 km by motorbike.

Answers
Answer:
W = 10
L = 20
Step-by-step explanation:
2L + 2W = 60
L = 2W
Substitute for L in the first equation
2(2W) + 2W = 60
4W + 2W = 60
6W = 60
W = 10
Plug in W in the first equation
2L + 2(10) = 60
2L + 20 = 60
2L = 40
L = 20
Plug both answers in both equations to check
2(20) + 2(10) = 60
20 = 2 * 10

Answer:
Step-by-step explanation:
so formula for the volume of a cylinder is:
(πr^2)*h
so the diameter is given to us which is
2r=10 cm
then r=5 cm
h=6 cm and r=5 cm so we just plug it in
(5^2)*6π
25*6π
150π cm^3 or approximately 471.239 cm^3
Answer:
I will give 2 possible answers. One of them involves a pi key and one is jsut 3.14. I don’t know if your suppose to use the Pi key or 3.14.
Possible answer #1 (with Pi key)= The volume would be about 471.24
Possible answer #2 (using 3.14)= The volume would be 471
Explanation:
Well first yoi gotta find the area of the circle. Using a pi key or 3.14 you follow the formula πr^2
The diameter is 10.
To find the radius divide diameter by 2 or multiply by half.
You’d get 5 and then using pi key or 3.14 number.
You’d have your area. Now multiply that by 6 the height and you have your final answer.

hannah is making a fleece tie blanket. it is 36 inches long. each tie will be 3/4 of an inch wide. how many times will she have
Answers
Proportionately, the number of times that Hannah will have to tie the blanket is 48 times.
What is proportion?Proportion is the relationship between two numerical values or variables. It shows the share or portion of a variable to the whole number.
Proportions are expressed as ratios, usually using fractions, decimals, or percentages.
Data and Calculations:The length of the fleece tie blanket = 36 inches
The width of each tie = 3/4 inches
The proportion of 3/4 inches to an inch = 0.75 (3/4)
The number of times to tie the blanket = 48 times (36/0.75)
Thus, the number of times that Hannah will tie the blanket is 48 times.

The length of a rectangular garden is 3 m greater than the width.the area of the garden is 70 m^2. Find the dimensions of the garden
Answers
Cause my dad came back with the milk
Answer:
Step-by-step explanation:
A = L x W
so you know that the length is 3m longer than the width, so you could use a formula to represent that
w = L + 3
you then substitute the second equation into the first to solve for L
70 = L x (l +3)
70 = L^2 + 3l
you could then rearrange the formula and solve for l using the quadratic formula
0 = L^2 + 3l - 70
l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2
then you solve for the two separate roots
l = -3 + 17 /2
l = 14 / 2
l = 7
or
l = -3 - 17 / 2
l = -20 / 2
l = -10
since a length cannot be negative, this root is not viable. therefore l = 7
to solve for w you would use
w = l + 3
w = 7 + 3
w = 10
hope this helps. :)))
