The sampling is a an example of random sampling.
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here: A truck manufacturer selects 3 trucks at random from each of 6 models for safety testing.
From each of six models selects 3 models and Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
Thus clearly the sample is random sampling.
Hence, The sampling is a an example of random sampling.

The first five terms of a sequence are 7, 10, 13, 16, and 19.
Which of the following functions define this sequence for all integers n ≥ 1?
Answer:
Option B is correct
For , the function for the given sequence is defined as;
Step-by-step explanation:
An arithmetic sequence is a sequence in which the difference between each consecutive term is constant.
An explicit formula for this arithmetic sequence given by;
where a represents first term
Since, the given sequences; 7 , 10 , 13 , 16 and 19
⇒ common difference(d) = 3 and a = 7
Since.
10 -7 = 3
13- 10 = 3 ....
The function which defined this sequence is;
using distributive property:
therefore, the function for the given sequence for all integers is;

Answer:
Input --- Output
1 ------------ 4
6 ------------9
8--------------11
Step-by-step explanation:
Given
Rule:
Output = Input + 3
Required
Complete the table
Represent the input with x and the output, y
So, the rule becomes
[tex]y = x + 3[/tex]
When Input = 1
[tex]x = 1[/tex]
[tex]y = x + 3[/tex]
[tex]y = 1 + 3[/tex]
[tex]y = 4[/tex]
This means:
Output = 4
When Input = 6
[tex]x = 6[/tex]
[tex]y = x + 3[/tex]
[tex]y = 6+3[/tex]
[tex]y = 9[/tex]
This means:
Output = 6
When output = 11
[tex]y = 11[/tex]
[tex]y = x + 3[/tex]
[tex]11 = x + 3[/tex]
[tex]x = 11 -3[/tex]
[tex]x = 8[/tex]
This means
Input = 8
So, the complete table is:
Input --- Output
1 ------------ 4

Answer: 38 for x, 61 for bottom left angle, 81 for top angle.
Step-by-step explanation:
Since all angles must add up to 180 degrees, that means that (2x+5) + (2x-15)+x must equal to 180. If you add and simplify correctly, x equals 38. The other angles can be figured out once you found x.

2 Cassie has a family photograph that measures 5-inches wide and 7-inches long. She wants to enlarge the photograph and hang it on the wall. If the length of the enlarged photograph is 87.5 inches, what is the width of the enlarged photograph?
Answer:
62.5 inches
Step-by-step explanation:
We would solve this using ratio
Width : Length = Width/Length
For the Original photo
5 inches : 7 inches = 5/7
For the enlarged phots
x : 87.5 inches = x/87.5
Equating both ratios together, we have:
5/7 = x /87.5
Cross Multiply
7x = 5 × 87.5
7x = 437.5
x = 437.5/7
x = 62.5 inches
Hence, the width of the enlarged photo is 62.5 inches

In one year, a school uses 13,270 pieces of white paper, 6,570 fewer pieces of blue paper than white paper, and 2,600 fewer pieces of yellow paper than blue paper. How many pieces of paper does the school use in all?
Answer:
24,070 the school uses in all
Step-by-step explanation:
You subtract 13,270 by 6,570 and you get 6,700 pieces of blue paper. Then, you subtract 6,700 by 2,600 and you get 4,100 pieces of yellow paper. Finally, you add the total of pieces of white, blue, and yellow paper and you get 24,070 for the total.
