Find the slope of the line passing through the points (3, 4) and (8, -3).
Answers
Answer: -7/5x
To find slope, you use the formula (THE FORMULA IS IN A PICTURE ATTACHED BELOW)
So by following this formula we would get
-3 - 4 -7
--------- = -----------
8 - 3 5
So the slope is -7/5x; BTW most teachers prefer if the answer is still in a fraction not a decimal because it is often easier to graph.
We want to find the slope of the line that passes through the points (3, 4) and (8, -3). We will see that the slope is equal to -7/5
We know that for a line that passes through the points (x₁, y₁) and (x₂, y₂) the slope is given by:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case, we know that the line passes through (3, 4) and (8, -3), then the slope is just:
[tex]a = \frac{-3 - 4}{8 - 3} = \frac{-7}{5}[/tex]
So we can see that the slope of that line is equal to -7/5.

Write a list of steps that are needed to find the measure of ∠B.
Answers
Step-by-step explanation:
Angle BCA + Angle BCD = 180 (Sum of angles on a straight line)
Angle BCA + 113 = 180
Angle BCA = 180 - 113
= 67
Angle BCA + Angle A + Angle B = 180 (Sum of angles in a triangle)
67 + 72 + Angle B = 180
139 + Angle B = 180
Angle B = 180 - 139
= 41
The measure of ∠B is m∠B = 41°.
What is a Triangle?A polygon which has three sides and three vertices is called as triangle.
The sum of all the angles of the triangle is 180°.
Given:
The sum of the exterior angle and adjacent angle with is 180°.
So, ∠BCD = 180 - 113 = 67°.
The sum of all the angles of the triangle is 180°.
So,
72° + 67° + ∠B = 180°.
∠B = 180° - 139°.
∠B = 41°.
Therefore, ∠B = 41°.

Where:
y(1) is the y value of the first pointx(1) is the x value of the first pointm is the slopeThe first point is (3,-4) and the second point is (3,8)
Let's first find the slope. The equation of m is given by:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{8-(-4)}{3-3}[/tex]
Here the slope is not defined, so we can not find the equation of this line, because it is not a function.

Answers
Answer:
1/26
Step-by-step explanation:
There is only one 6 of hearts and only one ace of diamonds.
The probability of selecting the 6 of hearts is thus 1/52, and that of selecting the ace of diamonds is also 1/52.
The probability of selecting the 6 of hearts or the ace of diamonds is the SUM of these two results: 1/52 + 1/52 = 2/52 = 1/26.

In a random sample of 8 residents of the state of Montana, the mean waste recycled per person per day was 3.0 pounds with a standard deviation of 0.23 pounds. Determine the 99% confidence interval for the mean waste recycled per person per day for the population of Montana. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answers
Answer:
at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )
Step-by-step explanation:
Given the data in the question;
sample size n = 8
mean x' = 3.0
standard deviation σ = 0.23
To calculate the confidence interval, we use the following expression;
x' ± [tex]t_{\alpha /2, df[/tex]( σ/√n) ------- let this be equation
now, at 99% confidence interval;
∝ = 1 - 99% = 1 - 0.99 = 0.01
degree of freedom df = n - 1 = 8 - 1 = 7
hence t-critical value = 3.499
in equation 1, we substitute in our values;
⇒ 3.0 ± 3.499( 0.23/√8 )
⇒ 3.0 ± 0.2845
⇒ 3.0 - 0.2845, 3.0 + 0.2845
⇒ ( 2.7155, 3.2845 )
Therefore at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )
