What is the average of 66 and 41?
Answer: 53.5
Step-by-step explanation:
To determine the average of any group of numbers
You must first add them all together
Then you must divide the sum by the amount of number in the group
In this case, we have 2 numbers
So let's add them
66 + 41 = 107
Now divide 107 by 2
107/2 =53.5
A coin is flipped 18 times. Three of the times the coin landed on heads and the rest of the times tails. What is the difference between the THEORETICAL and EXPERIMENTAL probability of landing on heads? *
Answer:
the experimental probability is based on the results of the experiment which yielded heads 1 out of 6 times; in theory, the results of flipping a coin and landing on heads would be 1 out of 2

1. Write in interval notation: 2|3-4x|+5>4
2. Write in set builder notation: |2-3x|=|x-3|
Answer:
See bolded below
Step-by-step explanation:
1. First solve the inequality:
2|3-4x|+5>4 [subtract 5 from both sides]
2|3-4x| > - 1 [divide both sides by 2]
|3-4x| > - 1/2
Since all absolute values are always greater than or equal to 0, the solution would be: All Solutions. Respectively in interval notation we have (- ∞, ∞)
2. Start by solving the equation:
|2-3x|=|x-3|,
2-3x = x-3, 2-3x = -(x - 3)
x = 1.25, x = -0.5
In set builder notation: { x | x ∈ {1.25, -0.5} }
EXTRA POINTS---Set up an equation and find the value of x.
Answer:
10)
180-3x =x (corresponding angles are equal)
x=45°
11)180-5x=3x ( same reason)
x=10°
12)180-6x=3x(same reason)
x=20°
Answer: See explanation
Step-by-step explanation:
10) Same side interior angles add up to 180°
3x + x = 180
4x = 180
x = 45
11) Same side interior angles add up to 180°
5x + 3x = 180
8x = 180
x = 22.5
12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well
6x + 3x = 180
9x = 180
x = 20

Step-by-step explanation:
Brooke multiplied 3 and 9 and got 17 Brooke knows her answer is wrong because she know it should be approximately
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30

Answer:
4+2 then 3+7 then what is 10x6=60 so 60 is the area
Step-by-step explanation:
Answer:
if you cut it, you would have a sqaure and a small rectangle, and just use a simple method for this, base times height, and for the sqaure it would be 12, and for the small rectangle all you need to do is subtract to find the side, such as seeing 4 for the side of the square the side, so it would be 3 and 1 which is 3 so 12+3 is 15 the area is 15.

Letter D! That's the answer
Answer:
C. y = 4
Step-by-step explanation:
[tex] \sin \: 30 \degree = \frac{y}{8} \\ \\ \frac{1}{2} = \frac{y}{8} \\ \\ y = \frac{8}{2} \\ \\ y = 4[/tex]
(2j + 5) + (3j + 5)
Answer:
5j+10
Step-by-step explanation:
In this question, you cannot find the answer to j, so you would just be simplifying the equation. So you would break the equation up into different parts and put the like parts together. So that it would be: (2j+3j)+(5+5)
5+5=10. So the answer is: 5j+10
the volume of a soap bubble is 2,308.4 mm ^3. Find the radius and diameter of the soap bubble. Use 3.14 for pi
Answer:
r = 8.2mm
d = 816.4mm
Step-by-step explanation:
Let the soap be spherical in nature
Volume of a sphere = 4/3 πr³
r is the radius
Given that V = 2308.4mm^3
Substitute
2308.4 = 4/3 πr³
2308 = 4/3 (3.14)r³
2308.4 * 3 = 12.56r³
6,925.2 = 12.56r³
r³ = 6,925.2 /12.56
r³ = 551.37
r = 8.2mm
diameter = 2r
diameter = 2(8.2)
diameter = 16.4mm
what are the 3 angle measures in the triangle shown below
9514 1404 393
Answer:
B. 39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
(3x +1) +(11x -4) +(5x -7) = 180
19x -10 = 180 . . . . . collect terms
19x = 190 . . . . . . . . add 10
x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
3·10 +1 = 3111·10 -4 = 1065·10 -7 = 43The appropriate choice is ...
B. 31°, 106°, 43°

Can someone tell me about proportions??? PLEASE I NEED HELP ASAP
Answer: A ratio is one thing or value compared with or related to another thing or value; it is just a statement or an expression, and can only perhaps be simplified or reduced. On the other hand, a proportion is two ratios which have been set equal to each other; a proportion is an equation that can be solved.

Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63
