Step-by-step explanation:
y=1
A straight line in slope (m) and intercept (c) form is:y=mx +c
In this example, y is a straight line of slope 0 and y −intercept of 1 ∴ y =0⋅

Copy the figure at right. Calculate the measure
of each lettered angle. Explain
how you determined the
measures d and h.
The angles of each letter are as follows:
∠a = 124°
∠b = 56°
∠c = 56°
∠d = 38°
∠e = 38°
∠f = 76°
∠g = 66°
∠h = 104°
∠k = 76°
∠n = 86°
∠p = 38°
∠a = 180 - 56 = 124°(total angle on a straight line)
∠b = 56°(vertically opposite angles)
∠c = 56°(corresponding angle to ∠b) Note this is possible because there are 2 parallel lines and a transversal.
2∠d + ∠d + 66 = 180 (sum of angles in a triangle)
3∠d = 180 - 66
3∠d = 114
∠d = 114 / 3
∠d = 38°
∠d = ∠e (given)
Therefore,
∠e = 38°
∠d + 66 + ∠f = 180
38 + 66 + ∠f = 180
∠f = 76°
Recall external angle of a triangle is equals to the sum of the opposite angles. Therefore,
∠f + ∠g = ∠d + ∠h
∠f + ∠g = 38 + 104
76 + ∠g = 142
∠g = 66°
∠d is one of the base angles of an isosceles triangle. Therefore base angles of the isosceles triangle are equal. This means the other base angle opposite ∠d in the isosceles triangle is congruent to ∠d.
Therefore,
2∠d + ∠h = 180(sum of angles in a triangle)
76 + ∠h = 180
∠h = 180 - 76
∠h = 104°
∠h + ∠k = 180 (sum of angles on a straight line)
∠k = 76°
∠n = 180 - ∠d - ∠c (angles on a straight line)
∠n = 86°
∠p = 180 - 56 - ∠n (sum of angle in a triangle)
∠p = 38°
Therefore, the angles of the letters are:
∠a = 124°
∠b = 56°
∠c = 56°
∠d = 38°
∠e = 38°
∠f = 76°
∠g = 66°
∠h = 104°
∠k = 76°
∠n = 86°
∠p = 38°

A hotel reservation number consists of 3 digits, followed by 3 letters, followed by 3 digits. How many different reservation numbers are possible?
Step-by-step explanation:
since there are 26 letters in the alphabet
and there are 10 numbers
without restrictions
10×10×10×26×26×26×10×10×10=17,576,000,000 reservation numbers are possible
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The number of different reservation numbers that are possible is 17,576 × 10⁶.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that A hotel reservation number consists of 3 digits, followed by 3 letters, followed by 3 digits.
Since each place can be taken by the digits each place will have 10 possible outcomes, [0,9]. Similarly for each place that can be taken by the alphabet can be taken by 26 different digits.
Therefore, the number of different reservation numbers that are possible is,
Number of different reservations = 10 × 10 × 10 × 26 × 26 × 26 × 10 × 10 × 10
= 17,576 × 10⁶
Hence, the number of different reservation numbers that are possible is 17,576 × 10⁶.

One number exceeds another by 20 and their sum is 30. Find the two numbers.
Answer:
25 & 5
Step-by-step explanation:
x+x+20=30
2x+20=30
2x=10
x=5
x+20=25
If One number exceeds another by 20 and their sum is 30 then the two numbers are 5 and 25.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that One number exceeds another by 20 and their sum is 30.
By the given data the two numbers are x+20 and x
As the sum of two numbers is 30
x+x+20=30
Add the like terms
2x+20=30
Subtract 20 on both sides
2x=10
Divide both sides by 2
x=5
So the two numbers are 5 and 5+20 which is 25
Hence, the two numbers are 5 and 25.

Step-by-step explanation:
Don't worry my friend, we have the power of order of operations!!
Okay, so first start by replacing the variables with the given numbers.
a(b - 1)^2 = 8(4 - 1)^2
Now do whats in the parentheses.
(4 - 1) = (3)
Next, we do 3 x 3 . This is because the three is squared.
(3)^2 = 9
Finally, multiply by 8.

A sample of 50 drills had a mean lifetime of 12.17 holes drilled when drilling a low-carbon steel. Assume the population standard deviation is 6.37.Construct a 95% confidence interval for the mean lifetime of this type of drill
Using the z-distribution, it is found that the 95% confidence interval for the mean lifetime of this type of drill, in holes drilled, is (10.4, 13.94).
We are given the standard deviation for the population, hence, the z-distribution is used. The parameters for the interval is:
Sample mean of [tex]\overline{x} = 12.17[/tex]Population standard deviation of [tex]\sigma = 6.37[/tex]Sample size of [tex]n = 50[/tex].The margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which z is the critical value.
We have to find the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.
In this problem, [tex]\alpha = 0.95[/tex], thus, z with a p-value of [tex]\frac{1 + 0.95}{2} = 0.975[/tex], which means that it is z = 1.96.
Then:
[tex]M = 1.96\frac{6.37}{\sqrt{50}} = 1.77[/tex]
The confidence interval is the sample mean plus/minutes the margin of error, hence:
[tex]\overline{x} - M = 12.17 - 1.77 = 10.4[/tex]
[tex]\overline{x} + M = 12.17 + 1.77 = 13.94[/tex]
The 95% confidence interval for the mean lifetime of this type of drill, in holes drilled, is (10.4, 13.94).
