Answer: m = 0
Step-by-step explanation:
Answer:
m=0
Step-by-step explanation:
The slope formula is: m=y1=y2/x2=x1
where (x₁, y₁) and (x₂,y₂) are the points on the line.
The points given are (-2,8) and (-22,8). Therefore,
x1=-2
y1=8
x2=-22
y2=8
Substitute the values into the formula.
m=8-8/-22-2
Solve the numerator. Subtract 8 from 8.
m=0/-22+2
Zero divided by any number is zero, so we automatically know the slope is zero.
m=0
The slope of the line is 0
Another geometry problem
Answer:
70 degrees
Step-by-step explanation:
2x+15=4x-5
subtract 2x from both sides
15=2x-5
add 5 to both sides
2x=20
divide both sides by 2 to get x by itself
x=10
You now have to add the equations together and plug in the x
(2(10)+15) + (4(10)-5)
(20+15) + (40-5)
35+35= 70
70 degrees

A sample of 18 randomly selected women is obtainedand the blood platelet count of each subject is measured. The mean is 253.9 and the standard deviation is 63.6. What is the margin of error (round to the nearest tenth)?
Answer:
Margin of error = E = 40
Step-by-step explanation:
Assuming 99% confidence level
Given that x = 253.9
s.d = 63.6
n = 18
Degrees of freedom = df = n - 1 = 18 - 1 = 17
At 99% confidence level the t is, α = 1 - 99% = 1 - 0.99 = 0.01
α/2 = 0.01 / 2 = 0.005
t α/2,df = t,0.005 = = 2.680 (using student t table)
Margin of error = E = t α/2,df * (s.d/√n)
Margin of error = 2.680*63.6/√18
Margin of error = 2.680*63.6/4.242641
Margin of error = 2.680*14.99066265564303
Margin of error = 40.17
Margin of error = E = 40

Anthony and Michelle have £65.25 between them. Anthony's amount is two thirds of Michelle's amount. How much money does each have?
Answer:
43.50
Step-by-step explanation:
MULTIPLE THE 2 NUMBERS
a. The amount of money that Anthony has is £26.1.
b. The amount of money that Michelle has is £39.15.
Let Anthony's amount be A.Let Michelle's amount be M.Given the following data:
Total amount = £65.25To find the amount of money each of them have:
In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):
Translating the word problem into an algebraic expression, we have;
Anthony's amount is two thirds of Michelle's amount:
[tex]A = \frac{2M}{3}[/tex] ....equation 1
Anthony and Michelle have £65.25 between them:
[tex]A+M=65.25[/tex] ...equation 2
Substituting eqn 2 into eqn 1, we have:
[tex]\frac{2M}{3} +M=65.25\\\\2M +3M =195.75\\\\5M = 195.75\\\\M= \frac{195.75}{5}[/tex]
M = £39.15
To find the value of A:
[tex]A = \frac{2M}{3}\\\\A = \frac{2\times39.15}{3}\\\\A = \frac{78.3}{3}[/tex]
A = £26.1

This is a special cube, which has numbers from 1 to 6 marked on its six faces. (Each number is marked on exactly one face.) Also, the sum of each pair of opposite faces is the same
Answer:
This is a die used to play games. Well we generally use more than one, so we use dice. The addition of each pair of opposite sides always yields 7:
1 + 6 = 72 + 5 = 73 + 4 = 7Dice games are very popular and they can also help understand how math and probability work. As with all games, probability always favors the house, but the risk of loss is part of the entertainment.

Determine the pattern rule for the table and write it as an equation.
Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:
[tex]y = mx+b[/tex]
Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the values
[tex]m = \frac{65-75}{2-1}\\m = -10[/tex]
Putting the value of slope
[tex]y = -10x+b[/tex]
Putting a pair of input-output in the equation (1,75)
[tex]75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85[/tex]
Putting the value of b
[tex]y = -10x+85[/tex]
Hence,
The rule is: y = -10x+85

A shape is shown on the centimetre grid below.
+
Work out the area of the shape
after it has been enlarged by
scale factor 2
State the units of your answer.
The area of the figure after dilation would be 20 square units.
What is scale factor? How it is used in Dilating coordinates?
Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-
K = a/b.
If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).
Given is the 2 - D figure as shown.
Assume the length of each side as 1 units. Then after the dilation by K = 2, each side would be of 2 units. Then, the area of the figure would be -
A = 5(2 x 2) = 5 x 4 = 20 square units
Therefore, the area of the figure after dilation would be 20 square units

Maria and Franco are mixing sports drinks for a track meet. Maria uses 23 cup of powdered mix for every 2 gallons of water. Franco uses 114 cups of powdered mix for every 5 gallons of water.
Answer:
Maria
Step-by-step explanation:
Find the ratio of powdered mix to water for each drink.
For Maria:
(2/3 cup) / (2 gallon)
= 1/3 cup per gallon
For Franco:
(1 1/4 cup) / (5 gallon)
= (5/4 cup) / (5 gallon)
= 1/4 cup per gallon
Since 1/3 is bigger than 1/4, Maria's sports drink is stronger.
