Hi! 6 questions, find the slope of the line through the given points, ty! They should be practice questions
Answer:
3. undefined (vertical line)
4. 1
7. -4
8. 3
11. undefined (vertical line)
12. -1/3
Step-by-step explanation:
You can use the slope formula to calculate the slope which is (y2-y1)/(x2-x1)
3. (-4 - (-2)) / (6-6) denominator is 0 here so the slope is undefined (vertical line)
4. (7 - 1) / (-2 - (-4)) = 6 / 6 = 1
7. (1 - (-7)) / (2 - 4) = 8 / -2 = -4
8. (-1 - 5) / (0 -2 ) = -6 / -2 = 3
11. (3 - 0) / (-6 - (-6)) = 3 / 0 = undefined (vertical line
12. (2 - 3) / (-5 - (-2) = 1 / -3 = -1/3

A television has increased in price by 5%
the new price is £194.25. what was the original price?
Answer:
let the original price be X
now new price = original price + increment
increment = 5 % of X = X/20
new price = 194.25
now, 194.25 = X + X / 20 = 21X / 20
X = 194.25 * 20 / 21
X = 185
original price = 185

Please help me solve problems a - d.
By defining and solving systems of equations, we will see that:
a) the fraction is 40/56
d) the fraction is 15/21.
How to write the equations?
We have the fraction 5/7 and we want to write it in different ways.
a) First we want to find a number a/b such that:
a/b = 5/7
a + b = 96
This is a little system of equations, to solve this, first we can rewrite the first equation as:
7a = 5b
Now we can isolate a on the second equation:
a = 96 - b
And replace that on the other equation:
7*(96 - b) = 5b
And now we can solve this for b.
672 - 7b = 5b
672 = 5b + 7b = 12b
672/12 = b = 56
And we know that:
a = 96 - b = 96 - 56 = 40
Then the fraction is 40/56
d) This time we want the denominator to be 9 less than twice the numerator.
in a/b, a is the numerator and b is the denominator.
So this time we have:
a/b = 5/7
b = 2a - 9
We can rewrite the first equation again:
7a = 5b
And then replace the other equation in the right side:
7a = 5*(2a - 9)
And now solve this for a.
7a = 10a - 45
45 = 10a - 7a = 3a
45/3 = a = 15.
And:
b = 2a - 9 = 2*15 - 9 = 21
Then the fraction is 15/21.

The number of DVDs in a random person's home collection is counted for a sample population of 80 people. The mean of the sample is 52 movies, the entire population is known to have a standard deviation of 12 movies. Assuming a 99% confidence level, find the margin of error.
A) 59.4671
B) 2.6296
C) 38.6536
D) 3.4547
In a case whereby the number of DVDs in a random person's home collection is counted for a sample population of 80 people the mean of the sample is 52 movies, the entire population is known to have a standard deviation of 12 movies then the margin of error is 3.46 moves.
How can the the margin of error be calculated?The concept that will be used here is the formular to find the error
E=z∝/2 σ/√ n
n= number of the samples= 80
σ = standard deviation = 12 moves
confidence level = (1-∝) = (1- 0.99) = 0.001
σ/2 = 0.005
Then the looking up for Z value of Z(0.005) = 2.58
E= 2.58 *12/√80

Jose paid $1.12 for a dozen eggs at his local grocery store. Determine the cost of 18 eggs.
Answer:
$1.68
Step-by-step explanation:
1 dozen is 12.
18 is the same as 12 + 6
6 eggs is half of 12 eggs.
Since 12 eggs cost $1.12, then 6 eggs cost half of $1.12, or $1.12/2 = $0.56.
18 = 12 + 6, so
the price of 18 eggs = the price of 12 eggs + the price of 6 eggs.
price of 18 eggs = $1.12 + $0.56 = $1.68
