Answer:
Dependent Events
Step-by-step explanation:
Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.
If the first ball is chosen the probability will 1/3 leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3. In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.
In this the events are called dependent events.
Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.
According to the US Census, the percent of residents aged 65 or older in the 50
states and District of Columbia has mean 13.26% and standard deviation of
1.67%. Find and interpret the standardized scoreſfor the state of Colorado, which
had 9.7% of residents age 65 or older. *
Answer:
z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean.
Step-by-step explanation:
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean

Answer: 7.5 batches
Step-by-step explanation:
60/6 is 10, so she needs to make 10 batches in total.
10-2.5=7.5
Answer:
no. of muffins = 60 muffins
no of muffins in each batch = 6 muffins
no. of batches which got over = 2.5 batches
no. of muffins baked = 6 * 2.5 = 15
no. of muffins to be baked = 60 - 15 = 45
no. of batches required to bake 45 muffins = 45 / 6 = 7.5

what is the solution to the systems of equations? equations - 3x-y= -17 , x-y= -13
Answer:
x=1 y=14
multiply x-y=-13 by 3 so the x would cancel out. solve for y
then plug in y to one of the equations to get x
Answer: the answer is x= -2 , y=11
Step-by-step explanation:
First
1: we have to find the answer for x in x-y= -13
2: add y on both sides of the equation
3: we will get x= -13+y
Second
1: Substitute x in 3x-y= -17 with x=-13+y
2: then you will get 3(-13+y)-y= -17
3: multiply 3 with -13 and y
4: you will get -39+3y-y =-17
5: add 3y and -y
6: you will get -39+2y= -17
7: add 39 on both sides of the equation
8: you will get 2y=22
9: divide 2 on both sides
10: you will get y= 11
Third
1: plug 11 for y in x= -13+y
2: then you will get x= -13+11
3: you will x= -2
So x= -2 and y= 11

Solve:3x+3y=27 and its algebra
Answer: X=9-y
Step-by-step explanation:
Answer:
x = 9 - y
y = 9 - x
Step-by-step explanation:
Solving for X:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]x = 9 - y[/tex]
Solving for Y:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]y= 9 - x[/tex]
Hence, the answer for x is x = 9 - y and the answer for y is y = 9 - x.

What is the length of the outside of a circle called
Answer:
The distance around a circle on the other hand is called the circumference (c).
Step-by-step explanation:
A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference. All points on the edge of a circle are the same distance to the center.
The length of the outside of a circle is called the "circumference."
The circumference is the total distance around the outer boundary of the circle.
The distance cover while completing one full lap around the track is equivalent to the circumference of the circle.
The formula to calculate the circumference (C) of a circle is:
C = πd
where π (pi) is a mathematical constant equal to 3.14159, and d represents the diameter of the circle.
The formula for circumference in terms of the radius is:
C = 2πr

The total length of three sides of the square is in., so the side length of the square is

Image of figure is missing so i have attached it.
Answer:
The total length of three sides of the square = 36 in
Side length of square = 12 in
A_triangle = 48 in²
Area of square = 144 in²
Total area of figure = 192 in²
Step-by-step explanation:
Total perimeter = 56 inches
Let the side of the square be s.
Thus, perimeter of the 3 sides of the square = 3s
Therefore, adding all the external sides of the figure, we have;
3s + 10 + 10 = 56
3s + 20 = 56
3s = 56 - 20
3s = 36
s = 36/3
s = 12
Area of triangle is given by the formula;
A_triangle = ½bh
Where;
b is base
h is height
Thus;
A_triangle = ½ × 12 × 8
A_triangle = 48 in²
Area of square = 12 × 12 = 144 in²
Total area of figure = 144 + 48 = 192 in²
The perimeter of a square is given as 8x+20 expression

This equilateral triangle has side lengths of 6 inches and a height of approximately 5 inches. Find the area, given these dimensions.
To find the area of a triangle we use this equation:
[tex]\frac{1}{2} bh\\[/tex]
b= base
h= height
So since we are given the information that the sides are 6 and the height is 5 we simply can plug the information right into the equation:
