there are 240 students who attend Elmwood school. Two thirds of the students have brown hair. how many students have brown hair? how many students do not have brown hair?
Answers
Answer:
160 has brown hair while
80 do not have brown hair
Step-by-step explanation:
two third means 2/3
therefore to find how many student have brown hair,
we say- 2/3 x 240 = 160
since we know that 160 students have brown hair, we just subtract it from 240
i.e 240 - 160 = 80

Hope uses the equation, 1 +1+y=4. to represent the situation.
What does the variable y represent in the equation?
Choose 1 answer:
Number of yo-yos Hope made
Number of meters of string in third yo-yo
Total number of meters of string Hope used
Answers
Answer:
The variable Y represents the number of meters of string in the third yoyo
Step-by-step explanation:
In this equation y stands for the unknown variable. The equation tell you that hope made 3 different yo-yos so the number of yo-yos hope made isn't unknown, meaning, it cant be the first answer. The problem also tells you that hope used a total of 4 meters of string which means that the total number of string used isn't the unknown variable. The number of meters of string in the third yo-yo is the only number that isn't. This makes the number of sting used in the third yo-yo the unknown variable, making it y.

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)

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

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.
