P(a triangle or a square is chosen first)

Step-by-step explanation:

Probability of an outcome is the ratio of number of favorable outcome to total number of outcomes.

Total number of outcomes= 5 + 2 + 2 + 4 = 13

P(a triangle or a square is chosen first) = P(a triangle chosen first) + P(a square chosen first)

P(a triangle or a square is chosen first)

There total quantity of shapes is 5 + 2 + 2 + 4 = 13. The total quantity of triangles and squares is 2 + 5 = 7. The probability of choosing a triangle or a square first is 7/13

Question
Which scatter plot represents the data in the table? Park patrons Number of dogs 7 4 6 2 9 7 8 6 5 3 7 7 3 1 4 3
Solution 1
In order to answer this question, you need to know what should be in the x axis and what should be in the y axis.

As for this one, you have given the information of the table:
Park patrons Number of dogs
7 4
6 2
9 7
8 6
5 3
7 7
3 1
4 3

The value in the x axis should be the
Park patrons
The value in the y axis should be the Number of dogs
Question
There are 10 grams of fat in a serving of sausage. Each serving is 100 calories. How many calories are from fat
Solution 1
10 calories i believe because if you divide 100 divided by 10 that will equal 10
Solution 2
10 calories I think because
100/10=10
Question
What is the 10th term in the pattern with the formula 5n + 100?
Solution 1
Easy
first term is n=1
so 10th term is n=10

5(10)+100=50+100=150

150 is 10th term
Question
Gavin and Seiji both worked hard over the summer. Together, they earned a total of $425. Gavin earned$25 more than Seiji. How much did each of them earn? (a) Write a system of two equations with two variables to model this problem. (b) Use substitution or the elimination method to solve the system. (c) Graph both equations. (d) Answer the question.
Solution 1
Let the money Seiji got be x and Gavin, y.

Total is 425.

So, x + y = 425

Gavin got 25 more than Seiji.

So, y = x + 25

I will use substitution method.

Substitute y = x + 25 in x + y = 425.

x + x + 25 = 425

2x + 25 = 425

2x = 400

x=$200 So, x is Seiji and he got$200.

For Gavin, substitute x in the equation of y.

y = x + 25

y = 200 + 25

y = $225 So, y is Gavin and he got$225.

For the graph part, I don't know how to show you. Hope you will be able to do the rest by yourself. If you need help with graphing, you may use desmos.com
Solution 2
200 for Seiji, and 225 for Gavin.
Question
2. The length of a rectangle is 5 mm longer than its width. Its perimeter is more than 30 mm. Let w equal the width of the rectangle. (a) Write an expression for the length in terms of the width. (b) Use expressions for the length and width to write an inequality for the perimeter, on the basis of the given information. (c) Solve the inequality, clearly indicating the width of the rectangle.
Solution 1
P=2(L+W)
L=5+W
P>30
30<2(L+W)
divide 2
15<L+W
15<5+W+W
15<5+2W
minus 5
10<2W

5<W

A. L=5+W
B. P=2(5+W+W)
C. 5<W
Question
Find two consecutive whole numbers that 52 lies between.
Solution 1
Im going to go with a wild guess and say 49 and 64
Solution 2
Think about which perfect squares lies on the immediate left of 52 and which lies on the immediate right of 52. 49 ---- 52 ------- 64 After that, take the square roots of each of the three numbers.
Question
1. Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. Find the number of liters of 20% acid solution in the new mixture. Construct a table to organize the information, and show all of your work to solve the problem.

-------
Equation:
acid + acid = acid
0.08*12 + 0.20x = 0.16(12+x)
-------

8*12 + 20x = 16*12 + 16x
4x = 8*12
x = 24 Liters (amt. of 20% solution needed)
