Answer:
Probably Dog.
Step-by-step explanation:
Since there is more dogs than anything else, it would probably be a dog.
Answer:
Total pets available
20 pets
Cat 0.2 --> 20%
Dog 0. 35 --> 35%
Snake 0.05 --> 5%
Rabbit 0.15 --> 15%
Bird 0.25--> 25%
Step-by-step explanation:
Total pets are:
cats + dogs + snakes + rabbits + birds
4 + 7 + 1 + 3 + 5 = 20 pets available for adoption
To find probability dived the number available of each pet by the total number of pets available.
Cat
4/20 = 0.2 --> 20%
Dog
7/20 = 0. 35 --> 35%
Snake
1/20 = 0.05 --> 5%
Rabbit
3/5 = 0.15 --> 15%
Bird
5/20 =0.25--> 25%

Professor Plum is standing 10 feet from a streetlamp. The light from the lamp is making his
shadow 8 feet long. He estimates that the angle of elevation from the tip of his shadow to the
top of the streetlamp is 40. About how high is the streetlamp? (6 points)
Answers
Answer:
15.10 ft
Step-by-step explanation:
It would be helpful to draw the figure from the problem statement above. Drawing it, would give you a right triangle shape where the base is equal to 10 ft + 8 ft = 18 ft with the angle of 40 degrees. We use knowledge on trigonometric functions to solve this.
tan (theta) = opposite side / adjacent side
tan 40 = x / 18
x = 15.10 ft

Answers
Answer:
105 degrees
Step-by-step explanation:
The sum of the angles on a triangle must always equal 180 degrees. We know that two angles are 28 and 47, so the third angle must be 105.
28 + 47 + x = 180
75 + x = 180
75 - 75 + x = 180 - 75
x = 105
Answer:
105 degrees
Step-by-step explanation:
28+47=75
180-75=105

Answer:
13/2 = 6.5
12 x 6.5 = 78
? = 78
13/2 = 78/12
Step-by-step explanation:
13 apples ÷ 2 pies = 6.5 apples per pie
12 pies x 6.5 apples per pie = 78 apples for 12 pies
? = 78 apples for 12 pies
13/2 = 78/12

scatterplot.
Answers
Answer:C
Step-by-step explanation:
By visual inspection, the best-fitting regression model for the data plot is the linear regression.
What is a regression model?A regression model determines a relationship between an independent variable and a dependent variable, by providing a function.
Determining the regression model :-
From the graph, we can see that the points appears to be on a straight line such that, as the x values increases, the y values also increases,
This type of model is a linear regression model.

Answer:
235.2
Step-by-step explanation:
147 * 1.60 -> this way is an all in one calculation but to double check you can take 60% of 147 (147 * .60 = x ) and add that value to 147 so... 88.2+147=235.2

Step-by-step explanation:
So all you have to do is this 147 * .60 = 88.2
8) Lea and Elisa each improved their yards by planting hostas and geraniums. They
bought their supplies from the same store. Lea spent $69 on 11 hostas and 7
geraniums, Elisa spent $64 on 10 hostas and 7 geraniums. What is the cost of one
hosta and the cost of one geranium?
Answers
Answer:
hosta = $5 each
geranium = $2 each
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
Leas's cost: 11 h + 7 g = 69
Elisa’s cost: 10h + 7g = 64
Where h is the price of one hosta and g is the price of one geranium.
Subtracting Elisa's cost to Leas's cost:
11 h + 7 g = 69
-
10h + 7g = 64
____________
h = $5
Replacing h in one equation:
11 (5) + 7 g = 69
55 +7g =69
7g = 69-55
7g= 14
g= 14/7
g= $2

3. The probability that an egg will break when kept in the store is 5 out of every 200. How many broken eggs do you expect from a crate containing 600 eggs?
Answers
Answer:
Step-by-step explanation:
The outcomes table is shown in the attached diagram. From the table, the total number of outcomes is 36.
i) the number of outcomes whose sum is 7 are 6 (1,6 2,5 3,4 4,3 5,2 6,1)
The probability that the sum of the two numbers that show up is 7 is
6/36 = 1/6
ii) the number of outcomes whose sum is even are 18
The probability that the sum of the two numbers that show up is even is
18/36 = 1/2
ii) the number of outcomes whose sum is greater than 9 is 6(4,6 5,5 6,4 5,6 6,5 6,6)
The probability that the sum of the two numbers that show up is greater than 9 is
6/36 = 1/6
3) this is a poisson distribution. We want to determine the mean.
Mean = np
p = 5/200 = 0.025
n = 600
Therefore,
Mean = 0.025 × 600 = 15 eggs
15 eggs are expected to be broken from a crate containing 600 eggs

The area of the patio is 216 square feet. Write an equation that represents the area of the patio
Answers
Answer:
[tex]216=2w \times w[/tex]
Step-by-step explanation:
Assuming that the patio is a rectangle, we have
[tex]A= l\times w[/tex]
Where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Now let's assume that the length of the patio is double than the width.
[tex]l=2w[/tex]
So, the equation that represents this problem is
[tex]216=2w \times w[/tex]
Answer:
x(x+6)=216
Step-by-step explanation:
It would actually be x instead of w because in the equation, they are using x's.
The equation would then be solved by making the equation x^2+6x=216.
By completing the square using (b/2)^2, you would then get the width to be 12 and the length to be 18.

[tex](3x-1)^{2} + 12x-4=0[/tex]
Can someone help me solve this. I am stuck at [tex]3(3x^{2} + 2x-1)[/tex]
Answers
To solve I would start by expanding the bracket and then collecting like-terms, and then re-factoring:
(3x - 1)² + 12x - 4 = 0
9x² - 6x + 1 + 12x - 4 = 0
9x² + 6x - 3 = 0
3(3x² + 2x - 1) = 0
From here you can factorise the bracket even further:
3(3x - 1)(x + 1) = 0
Then divide by 3:
(3x - 1)(x + 1) = 0
3x - 1 = 0
x = 1/3
x + 1 = 0
x = -1
I hope this helps! Let me know if you have any questions :)
Corey brought $54.50 to the art supply store. He bought a brush, a sketchbook, and a paint set. The brush was 1 6 as much as the sketchbook, and the sketchbook cost 3 4 the cost of the paint set. Corey had $2.00 left over after buying these items. What was the cost of each item?
Answers
Answer: The items cost as follows;
(a) Brush = $3.50, (b) Sketchbook = $21 and (c) Paint set = $28
Step-by-step explanation: First of all we shall assign letters to the unknown variables, hence we shall call the brush x, the sketchbook y, and the paint set we shall call z.
The total amount spent by Corey was $52.50 because after buying all he needed, he had $2.00 left out of a total of $54.50. This means his transaction can be expressed as follows;
x + y + z = 52.50
However, we know that the brush was 1/6 as much as the sketchbook, that is, if the sketchbook is y, then the brush which is x shall be 1/6 of y. Simply put, x = 1/6y or x = y/6.
Similarly, the sketchbook cost 3/4 of the paint set. If the paint set is z, that means y = 3/4z or y = 3z/4.
Note however that, if y = 3z/4, then by cross multiplication,
4y = 3z
4y/3 = z
Having derived that x = y/6 and z = 4y/3, we can substitute for the values of x and z into the original equation
x + y + z = 52.50
y/6 + y + 4y/3 = 52.5
using a common denominator which is 6, you now have;
(y + 6y + 8y)/6 = 52.5
By cross multiplication, you now have
15y = 52.5*6
15y = 315
Divide both sides of the equation by 15
y = 21
Therefore, if the sketchbook is y, then the sketchbook costs $21.
Also if the brush is x, then the brush costs
x = y/6
x = 21/6
x = 3.50 (The brush costs $3.50)
Also if the sketchbook costs 3/4 of the paint set, then
y = 3z/4
21 = 3z/4
21*4 = 3z
84 = 3z
Divide both sides of the equation by 3
28 = z (The paint set costs $28)

I bought 45 oz of flour. She used 15.6 oz to make a loaf of bread, 0.71 oz for each muffin. How many muffins were made if you have 18.04 oz left over?
Answers
Answer:
16
Step-by-step explanation:
Total weight of flour =45 ozWeight of flour used for bread =15.6 ozLeftover =18.04 ozTherefore:
Weight of flour used for muffin =Total weight of flour-(Weight of flour used for bread+Leftover)
=45-(15.6+18.04)
=45-33.64
=11.36 oz
Since each muffin is made with 0.71 oz of flour
Number of muffins made=11.36/0.71
=16
16 muffins were made.
