Three-sevenths of the T-shirts in a T-shirt shop are blue. Seven-eighths of those T-shirts are on sale. One-third of the blue
T-shirts that are on sale are size medium. What fraction of the shop's T-shirts are blue T-shirts that are on sale and are
size medium? Explain.
The fraction of T-shirts that are blue, medium, and on sale is
Out of all the T-shirts in shop, the fraction of T-shirts that are blue, medium, and on sale is x/8.
Let us assume the total number of shirts be x. So, the number of blue shirts in the shop are 3x/7.
Number of blue shirts on sale = 3x/7 × 7/8
Cancelling 7 common in numerator and denominator and performing multiplication
Number of blue shirts on sale = 3x/8
Number of blue shirts on sale medium in size = 3x/8 × 1/3
Cancelling 3 common in numerator and denominator and performing multiplication
Number of blue shirts on sale medium in size = x/8
Hence, the required fraction of T-shirts are x/8.

A spinner is spun 400 times.
The probabilities it lands on each colour are shown below.
The probability it lands on red is the same as the probability it lands on yellow.
Colour Red Green Brown Yellow
Probability 0.14 0.4
How many times would you expect it to land on each colour?
The likelihood that it will land on red is the same as the likelihood that probability it will land on yellow. In this case, 52.
What exactly is probability?
Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.
The probability of an event is a number between 0 and 1, with 0 generally denoting impossibility and 1 roughly denoting certainty.
based on the available facts;
Given, color likelihood Green Brown Yellow Red
P(R) + P(a) + P(B) + P(Y) = 1
2P(CR) + 0-74=1
P(R) 0.26/2
= 0.13 P(Y)
As it is span 400 times -
No. of times green= 0.2 off 400

A retired woman has $30,000 to invest but needs to make $3,000 a year from the interest to meet certain living expenses. One bond investment pays 15% annual interest. The rest of it she wants to put in a CD that pays 7%.
If we let x be the amount the woman invests in the 15% bond, how much in dollars will she be able to invest in the CD?
On the basis that the woman invests in the 15% bond, she be will able to invest $18,750 in the CD
What is the total expected interest from both investments?
The investment is based on the fact the investor is able to make $3,000 in interest from the bond and CD investments
total expected interest=$3,000
interest on bond investment=15%*x=0.15x
amount invested in CD=30000-x
interest on CD=(30000-x)*7%
interest on CD=2100-0.07x
total interest=0.15x+2100-0.07x
total interest=3000
3000=0.15x+2100-0.07x

8) The sum of four times a number, -1, six times a number, and 3
The expression for the statement is 4y - 1 = 3y + 4 and the number is 4.
The outcome of adding two or more numbers or phrases is known as the sum in mathematics. The sum is a method of bringing things together as a result.
Let's assume the number to be y.
Then,
4 times the number = 4y
6 times the number = 6y
Now, the sum of four times a number and -1 is equal to 6 times a number and 3.
4 × ( the number) + (-1) = 3 × ( the number) + 3
4 × (y) + (-1) = 3 × (y) + 3
4y - 1 = 3y + 3
Now, add 1 on each side:
4y - 1 + 1 = 3y + 3 + 1
4y = 3y + 4
Subtracting by 3y from each side:
4y - 3y = 3y + 4 - 3y

The term percentile and the related term percentile rank are often used in the reporting of scores from norm-referenced tests. For example, if a score is at the 86th percentile, where 86 is the percentile rank, it is equal to the value below which 86% of the observations may be found. In contrast, if it is in the 86th percentile, the score is at or below the value of which 86% of the observations may be found. Every score is in the 100th percentile.
The 25th percentile is also known as the first quartile (Q1), the 50th percentile as the median or second quartile (Q2), and the 75th percentile as the third quartile (Q3). In general, percentiles and quartiles are specific types of quantiles.

The formula for moose population, P, in terms of t, the years since 1990 would be P(t) = -110t + 4730.
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Let's consider x on the graph to be years since 1990 and y on the graph to be the number of Moose.
We have two points on the graph as (4, 4290) and (8, 3850)
Now we can find the slope of this line:
m = (y2 - y1)/(x2 - x1)
Substitution;
m = (3850 - 4290)/(8 - 4)
Solve the subtraction in the parenthesis;
m = -440/4
m = -110
Then we have the slope of the line, we can use the point-slope formula to find the equation for the line.
y - y1 = m(x - x1)
Substitution;
y - 4290 = -110(x - 4)
y - 4290 = -110x + 440
y - 4290 + 4290 = -110x + 440 + 4290
y = -110x + 4730
Since the formula that is being sought is supposed to be in terms of P and t, we will replace y with P and x with t.
P(t) = -110t + 4730
To predict the population in 2006, we have to determine the years from 1990 to 2006.
2006 - 1990 = 16
P(16) = -110 (16) + 4730
P(16) = -1760 + 4730
P(16) = 2970
Hence, The formula for moose population, P, in terms of t, the years since 1990 would be P(t) = -110t + 4730.

x = number of weeks
so, we need to see, what is the number of weeks it takes for both to have the same balance.
it takes both the same amount of weeks, of course.
so,
250 + 15x = 750 + 10x
