Answer:
Step-by-step explanation:
2(6x+5+2y)
Answer:
You basically multiply the number outside the parentheses by everything inside.
So 2 × 6x = 12x,
2 × 5 = 10,
2 × 2y = 4y.
So your answer is 2(6x + 5 + 2y).

The probability event A is .45, the probability of event B is.20. If A and B are independent events, what is the probability of A and B, P(A and B)?
0 2.25
25
.65
.09
Answer:
.09
Step-by-step explanation:
To find the probability of independent events, you multiply their individual probability.
so, .45 x .20 = .09

please help me i would really appreciate it
i will mark brainliest if you dont play around
Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.
the diameter of a bike wheel is 25 inches. If the wheelmakes 20 Complete rotations, how far does the bike travel?
Answer:
1571 in
Step-by-step explanation:
Given data
Diamter= 25 in
radius= 25/2= 12.5in
Circumference= 2πr
substitute
C=2*3.142*12.5
C=78.55in
In 1 revolution the bike will travel 78.55in
in 20 revolutions the bike will travel
=78.55*20
=1571 in

Answer:
[tex]E(x) = 99[/tex]
Step-by-step explanation:
Given
The attached table
Required
Number of times 3 or 4 will occur
First, we complete the table as follows:
[tex]P(1) + P(2) +......+P(6) =1[/tex]
[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]
Collect Like Terms
[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]
[tex]P(3)= 0.12[/tex]
The expected number of times is:
[tex]E(x)= n * P(x)[/tex]
So, we have:
[tex]E(x) = 300 * (0.12 + 0.21)[/tex]
[tex]E(x) = 300 * (0.33)[/tex]
[tex]E(x) = 99[/tex]

A system of equations is shown. 4x + 2y = 10
2x - 2y = 8
What is the value of x in the solution to the system?
Answer:
x=2
Step-by-step explanation:
2 (4x+2y=10 8x+4y=20
-4 (2x-2y=8 -8x+8y=-32
12y=-12 y=1
4x+2=10
4x=8
x=2
In the system's answer, x has the value of 3.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
We can solve this system of equations using the elimination method.
To eliminate y, we can add the second equation to the first equation. This gives:
(4x + 2y) + (2x - 2y) = 10 + 8
Simplifying the left side and combining the constants on the right side, we get:
6x = 18
Dividing both sides by 6, we get:
x = 3
Therefore, the value of x in the solution to the system is 3.

Luis is 0.25 meters shorter than Harry, if Luis is 1.7 meters tall determine Harry’s height.
Answer: 1.95
Step-by-step explanation:
Luis is Harry's height minus 0.25m, which means Harry is Luis' height plus 0.25m.
Luis + 0.25 = Harry
1.7 + 0.25 = 1.95 m

Answer:
width = 126 ft
Step-by-step explanation:
I'm going to assume that I am solving for width.
Area = width x length
84 = 2/3 x width
Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)
84 x 3/2 = width
width = 126 feet
The sum of two numbers is 11. Twice the first number minus the second number is 7
Find the numbers.
Answer:
6 and 5
Step-by-step explanation:
6 * 2 = 12
12 - 5 = 7
6 and 5 is your answer
Answer: 6; 5
Step-by-step explanation:
Based on the questions, we set up two equations, let the x be the first number, and y be the second number.
x + y = 11
2x - y= 7
x = 11 - y [Subtract y from both side]
2x - y = 7
2(11 - y) - y = 7 [Plug in 11-y for x, solve for y]
22 - 2y - y = 7
22 - 3y = 7
-3y = -15 [Subtract 22 from both side]
y = 5
x + y = 11 [Plug in 5 for y, solve for x]
x + 5 = 11 [Subtract 5 from both side]
x = 6
