I think the answer is y=2(17)+1.25.
Answer:
$2+$1.25x=$17
Step-by-step explanation:
You have to add the $2 to the $1.25 for each mile then multiply that by x to get $17. I think but I could be wrong
Which members are in the sample?
Table of Random Digits
126: 47934, 01885, 20967, 94841, 27015, 44184, 05108, 86788
127: 73786, 87922, 17887, 03752, 70494, 09483, 34655, 28603
128: 53537, 96428, 40115, 27467, 90826, 52358, 14570, 54184
129: 20266, 49844, 35186, 57228, 65170, 85907, 44662, 91487
130; 89214, 31076, 93733, 30746, 44086, 20432, 94732, 78616
The correct answer is the first one in the list of choices: 28, 40, 11 and 23.
There are other ways to randomly sample. This problem illustrates how random sampling can be accomplished using a printed random number table.
Mrs. Fuller needs to randomly sample four members from a population of size 47. Each member of the population is given a unique 2-digit number, in order from 01 to 47.
Mrs. Fuller has a random number table she wishes to use to randomly select four members. She chooses a line from the table, line 128, which reads as follows:
53537 96428 40115 27467 90826 52358 14570 54184
The numbers are separated into sets of 5; this is done for readability. The digits 0-9 appear randomly in each set of 5.
If we envision this line of random numbers as a series of 2-digit numbers, we can use the first four unique 2-digit numbers between 01 and 47 to represent the population members in our sample.
Note that we don't use repeats of numbers we have already selected; we need all four to be different.
Let's reformat the line of 5-digit numbers into a series of two-digit numbers instead.
53 53 79 64 28 40 11 52 74 67 90 82 65 23 58 14 57 05 41 84
Now let's go from left to right and look for the first four 2-digit numbers between 01 and 47. We can't use 53, 79 or 64; those are outside of our desired range.
The fifth 2-digit number is 28, so we can use that. Immediately after it are 40 and 11, so those are good. It's a bit further to the last usable 2-digit number, 23. The four numbers we select appear in BOLD below.
53 53 79 64 28 40 11 52 74 67 90 82 65 23 58 14 57 05 41 84
Hence, the correct answer is the first one in the list of choices: 28, 40, 11 and 23.

The time taken to mow the entire lawn will be 23 minutes.
Let the total time taken be represented by x.
Based on the information given, the total time needed will be:
52% × x = 12
0.52 × x = 12
0.52x = 12
x = 12/0.52
x = 23.08
Therefore, the time taken to mow the entire lawn will be 23 minutes.

Measures of the interior angles will be found as below.
Interior angles of a triangle is the three angles formed inside the triangle by its sides.
Exterior angles of a triangle is the three angles formed by extending the sides
Given that triangle has an exterior angle with a measure of 120°.
Let a, b and c be the interior angles of the given triangle.
The sum of the exterior angle and the corresponding interior angle is 180°.
Let a be the corresponding interior angle.
a + 120 = 180
a = 180 - 120
a = 60°
One of the interior angles is 60°.
Sum of the interior angles of a triangle is 180°.
Then a + b + c = 180
b + c = 120
If the triangle is equilateral, then all the angles will be 60°.
If it is right angle, angles will be 30° and 60°.
Hence the interior angles can be found as above.
