A shopkeeper bought 50 kg of sugar and sold 1/4th of the sugar. find the mass of sugar that was left
Answer:
12.5 kg
Step-by-step explanation:
50 divided by 4 = 12.5
Answer: 37.5kg
Step-by-step explanation:
When you hear "of", it indicates multiplication. When you multiply by 1/4, you can also divide by 4 to get the same answer. 50/4 = 12.5kg sold
But that isnt our net sugar because thats how much he sold. Subtract that from what he has currently, and youll get the sugar he has after selling the 1/4th.
50 - 12.5 = 37.5kg

Mae Ling earns a weekly salary of $325 plus a 7.5% commission
on sales at a gift shop. How much would she make in a work week if she sold
$5,800 worth of merchandise? Write in money format.
Answer:
$760
Step-by-step explanation:
Given data
weekly = $325
commission= 7.5%
if she sold $5,800 worth of merchandise
Her earnings will be
Week earning= base salary+ 7.5% of sales
Week earning= 325+ 7.5/100*5800
Week earning= 325+ 0.075*5800
Week earning= 325+ 435
Week earning= $760

Which box plot represents the data set 2, 4,4,8,10,12
Answer:
A.
Step-by-step explanation:
Give the data set: 2, 4, 6, 8, 10, 12.
Find the following:
Min, Q1, Median, Q3, and Max.
Min. = 2
Q1 = 4
Median = (6+8)/2 = 7
Q3 = 10
Max = 12
Check the box plot to see which one represents these values above.
Thus:
The correct box plot would have the whisker to your left at 2, representing the min value.
The Q1 would be at represented by the beginning box the edge of the rectangular box that starts at 4.
The median would be represented by the vertical line that divides the box which would be on 7.
The Q3 would be on the end of the box which is at 10.
The max would be represented by the other whisker that goes to our right, representing 12.
The box plot is that represents this data is the box plot given in option A.

Seventy-nine percent of products come off the line ready to ship to distributors. Your quality control department selects 12 products randomly from the line each hour. Looking at the binomial distribution, if fewer than how many are within specifications would require that the production line be shut down (unusual) and repaired?
a. Fewer than 7
b. Fewer than 9
c. Fewer than 6
d. Fewer than 10
Answer:
c. Fewer than 6
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
In the binomial distribution, an outcome is considered unusual if it is more than 2.5 standard deviations below the mean.
Seventy-nine percent of products come off the line ready to ship to distributors.
This means that [tex]p = 0.79[/tex]
Your quality control department selects 12 products randomly from the line each hour.
This means that [tex]n = 12[/tex]
Mean:
[tex]E(X) = np = 12*0.79 = 9.48[/tex]
Standard deviation:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.79*0.21} = 1.41[/tex]
Unusual:
[tex]9.48 - 2.5*1.41 = 5.96[/tex]
So fewer than 6 is considered unusual.
Find the distance from point P to the given line
Answer:
The distance from point P, P(-2,4) to the given line y= 2x-2 is 1.56
Step-by-step explanation:
We need to find the distance from point P to the given line
P(-2,4) , y= 2x-2
The formula used is: [tex]Distance=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }[/tex]
Where A, B and C are points of line i.e Ax+By+C=0
and x_1 and y_1 are points of P
So, y=2x-2 in Ax+By+C=0 is:
2x-y-2=0
A=2,
B=-1
C=1
Point given is P(-2,4)
x_1=-2
y_1=4
Putting values and finding distance
[tex]Distance=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }\\Distance=\frac{|2(-2)+-1(4)+1|}{\sqrt{(-2)^2+(4)^2} }\\Distance=\frac{|-4-4+1|}{\sqrt{4+16} }\\Distance=\frac{|-7|}{\sqrt{20}}\\Distance=\frac{7}{\sqrt{20} }\\Distance=\frac{7}{4.5}\\Distance=1.56[/tex]
So, the distance from point P, P(-2,4) to the given line y= 2x-2 is 1.56

Zach is building a new shed shaped like a square prism. He wants the height of the shed to be 2 feet less than the length and width. If he needs the volume to be as close as possible to 3174 ft 3 , what should the length be
Answer:
[tex]15.394\ \text{feet}[/tex]
Step-by-step explanation:
Let [tex]x[/tex] be the length and width of the base of the prism and,
[tex]y[/tex] be the height of the prism.
Now height of the prism is 2 feet less than the length and width.
So [tex]y=x-2[/tex]
Volume of the the square prism is [tex]3174\ \text{ft}^3[/tex]
[tex]x^2y=3174[/tex]
Now we graph both the functions.
The point at which they intersect each other is [tex](15.394,13.394)[/tex]
So, the length of the prism is [tex]15.394\ \text{feet}[/tex].

A university conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the study, 1.9% of the 457 members of a fitness association died. We are interested in the proportion of people over 50 who ran and died in the same eight-year period.
NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
Define the Random Variables X and P', in words. which of the following?
a.) X is the proportion of people who ran and died in the eight-year period, and P' is the number of people who ran and died in the eight-year period.
b.) X is the proportion of all runners that die, and P' is the number of all runners that die.
c.) X is the number of people who ran and died in the eight-year period, and P' is the proportion of people who ran and died in the eight-year period.
d.) X is the number of all runners that die, and P' is the proportion of all runners that die.

Find the slope of the line:
x - 5 = 0
Answer:
Undefined
Step-by-step explanation:
Add 5 to both sides to get the equation x=5. X=5 is a vertical line. The slope, or change in y / change in x would be undefined since the change in x is always zero. Anything divided by zero is undefined.
