11. Write down three different whole numbers so that: • the median of the three numbers is 13, the range of the three numbers is 5.
Step-by-step explanation:
Let the numbers be a, b, c in ascending order.
Mean is 7, i.e. (a+b+c)/3 = 7 or a+b+c=21
Median(middle number) is 5, i.e. b=5
Range is 8, i.e. c-a=8 or c=8+a
Solving the above three equations simultaneously, we have
a+5+8+a=21
a=4, hence c=12
Therefore the three numbers are 4, 5 and 12

Have a great day✧◝(⁰▿⁰)◜✧Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feet, and the diameters, in inches, recorded from 31 felled trees.

What is a 95 percent confidence interval for the slope of the population regression line?
Measuring the height of a tree is usually more difficult than measuring the diameter of the tree, confidence interval for the slope is mathematically given as
C=(0.396, 1.712)
What is a 95 percent confidence interval for the slope of the population regression line?Generally, the equation for the confidence interval is mathematically given as
[tex]C=\beta-tn-2, \alpha /2 (S.E)[/tex]
Where
[tex]\beta=1.054[/tex]
Therefore
C=(1.054-t29, 0.025*0.322)
C=(0.396, 1.712)
In conclusion, the 95 percent confidence interval is
C=(0.396, 1.712)

Answer:
the right answer is c(5) . because the last digit of the second number is 2 . every number that its last digit is 2 squared , the last digit of the result will always be 4 . also , in every number that its last digit is five , the result will also always be 5 . so if the last digit of the first number is 5 this equasion is correct (because the last digit of the answer is 9 )(5+4)

[tex]\frac{3}{6}=\frac{x}{600} \\[/tex]
Cross multiply to solve for x.
6*x = 3*600
6*x = 1800
x = 300

I’ve worked out that the 1st term is -5 but can’t work out the rest. I thought it was -77 but it’s wrong
Answer:
-5, 22, 292
Step-by-step explanation:

(i) n = 1 , 3n - 8
= 3 x 1 - 8
= -5
(ii) n = 10 , 3n - 8

(iii) n = 100 , 3n - 8
= 3 x 100 - 8

Using a graphing calculator, we have the following calculation summary:
Sum of X = 5956Sum of Y = 680Mean X = 661.7778Mean Y = 75.5556Sum of squares (SSX) = 50569.5556Sum of products (SP) = 7547.1111The regression equation is represented as:
ŷ = bX + a
Where:
b = SP/SSX
b = 7547.11/50569.56
b = 0.14924
a = MY - bMX
a = 75.56 - (0.15*661.78)
a = -23.20961
This gives
ŷ = 0.14924X - 23.20961

ŷ = 0.15x - 23.21

A shopkeeper bought 30 pens for 150 and sold 20 of them for 140. Find his profit or loss percentage
Answer:
Because the cost price of 30 pens = Rs. 150
So, the cost price of 1 pen = 150/30 =5
so, the cost price of 20 pens =
Rs. 5 x 20 = 100
Cp is Rs. 100
Sp is Rs. 140
So, profit = 140-100 = Rs. 40
Profit % = (Profit x 100)xCp
=(40 x 100)/100
= 4000/100
= 40% profit

Basically you would subtract 6.4 and 2.9 because there is a negative sign and they have the same variable. Then you would put it (2.9r)first since it is in order and you can't combine 7 and 2.9r so you leave it like that.
I need help with 15.) 17.) and 19.) I have attached the answers I just need help with how to solve them
Answer:
Step-by-step explanation:
They are all solved kind of the same way. If the vertex of the angle is outside of the circle, subtract the intercepted arcs and divide by 2
for 15) one arc is marked but you can figure out the other arc because there are 360 degrees in a circle 360 - 102 = 258. So the two arcs are 102 degrees and 258 degrees.
some of the problems you can set up the equation and solve.
17) 63 = {(360-x) - x} /2 multiply by 2
126 = {(360-x) - x} combine like terms
126 = 360 - 2x subtract 360
-234 = -2x divide by -2
117 = x
? = 117 degrees
