Janice's age is 35 years.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Ross age = x
Now,
Janice age = 5x ____(1)
Janice age = x + 28 _____(2)
From (1) and (2),
5x = x + 28
5x - x = 28
4x = 28
x = 7
Now,
Janice age.
= 5 x 7
= 35
Thus,
Janice's age is 35 years.

Find the distance between the pair of points (2,9) and (3,8).
Answer:
[tex]\sqrt{2}[/tex] units
Step-by-step explanation:
To find the distance between a pair of points, use the distance formula, [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (2,9) and (3,8) into the formula and simplify:
[tex]d = \sqrt{(8-9)^2+(3-2)^2} \\d = \sqrt{(-1)^2+(1)^2} \\d = \sqrt{1+1} \\d= \sqrt{2}[/tex]
So, the distance is [tex]\sqrt{2}[/tex] units.

George, Matthew and Isabelle invest money in a savings account, which pays compound interest of 3% p.A
The question is incomplete. The complete question is :
George, Matthew and Isabelle invest money in a savings account, which pays compound interest of 3% p.a.
a). George invested £ 4800. Work out the total value of his investment after 5 years.
Solution :
It is given that :
George invested amount of, P = £ 4800
Time of investment, t = 5 years
Rate of interest, r = 3 % p. a.
The total value will be :
[tex]$A=P(1+\frac{r}{100})^t$[/tex]
[tex]$A=4800(1+\frac{3}{100})^5$[/tex]
[tex]$A=4800\times (1.03)^5$[/tex]
[tex]A = 4800 \times 1.1592[/tex]
= 5564.16
Therefore the total value after 5 years = £ 5564.16

Find the rate of change for the situation. You run 7 miles in one hour and 14 miles in two hours.
A. 7 miles per hour
B. 2 hours
C. 2 miles per hour
D. 7 miles
Answer:
The answer is A.
To find speed/rate of change, divide distance by time.
7 mi/ 1 hour= 7 mph
14 mi/2 hour= 7mph
Step-by-step explanation:
Answer: A.7 miles per hour
Step-by-step explanation:
Given: You run 7 miles in one hour and 14 miles in two hours.
We know that .. The rate of change of function= (change in distance)/(change in time)
Therefore, the rate of change of function for the given situation= (14-7)/(2-1)= (7)/(1)
Hence the rate of change of function for the given situation= 7 miles per hour.

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.11 is calculated. What would this imply about the football team winning at home?
The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
A.The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
B. The scatter plot would not be represented by a line of best fit with a negative slope. C.There is a weak correlation between the football team playing at home and winning, and a causal relationship exists between the team playing at home and winning.
D. There is no causation and almost no correlation between the football team playing at home and winning.
Answer:
D
Step-by-step explanation:
Given a correlation coefficient of -.11 the correlation would be extremely weak therefore it would have almost no correlation or causation
Why? Well when the value of the correlation is between -.1 and .1 then the relationship is said to have no correlation
-.11 is very close to -.1 thus meaning it would have pretty much no correlation
Answer:
D. There is no causation and almost no correlation between the football team playing at home and winning.
Step-by-step explanation:
A correlation coefficient can be greather than or equal to -1, and less than or equal to 1.
If you have a negative correlation coefficient it means that the correlation between the two variables is a reverse relationship. When one of the variables increase the other one decrease.
The closes the correlation coefficient is to -1 or 1, the correlation is higher,
As -0,11 is not close to -1 it means that the correlation is almost 0 and it is not a correlation between the two variables.

the changes in Mr. Connor’s bank account for five days are $50.25, -$22.50, $50.25, -22.50, and -22.50. What is the mean change in his bank account? show your work
Answer:
8.6
Step-by-step explanation:
-22.50 x 3 = -67.50
50.25 x 2 = 100.50
100.50 + -67.50 = $43
43 divided by 5
=8.6

The mean change in Connor's bank account is $6.6.
What is mean?Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.
Given that,
Changes in Mr. Connor's bank account for five days are $50.25, -$22.50, $50.25, -22.50, and -22.50.
To find mean change in Connor's bank account,
First determine total change in Connor's bank account
Total change = 50.25 -22.50 + 50.25 - 22.50 - 22.50
= 33
Mean change = total change/ number of days
Mean change = 33/5
= 6.6
