A jar of marble ha 5 blue marble, 3 red marble, and 4 green marble. What i the probability of drawing a marble that i blue, and then, after replacing it, drawing a marble that’ green
The probability of drawing a marble that is blue, and then, after replacing it, drawing a marble that’ green is 5/36.
In the given question, a jar of marble has 5 blue marble, 3 red marble, and 4 green marble.
We have to find the probability of drawing a marble that is blue, and then, after replacing it, drawing a marble that’ green.
Total number of marbles = 5 + 3 + 4
Total number of marbles = 12
The probability of choosing the blue marble = Number of Blue Marble/Total number of marble
The probability of choosing the blue marble = 5/12
Now replacing the marble blue and getting the green marble = Number of Green Marble/Total number of marble
Now replacing the marble blue and getting the green marble = 4/12
Now replacing the marble blue and getting the green marble = 1/3
The probability of getting blue marble then green marble = The probability of choosing the blue marble × The probability of choosing the green marble
The probability of getting blue marble then green marble = 5/12 × 1/3
The probability of getting blue marble then green marble = 5/36

What does a residual of 2 mean?
The observed frequency of the cell is fewer than the expected frequency, according to a typical rule of thumb for interpreting the standardized residual: If the residual is less than -2. If the observed frequency is more than the expected frequency, it is greater than 2.
The meaning of a negative residual?
A negative residual indicates an excessively high anticipated value, and a positive residual indicates an excessively low expected value. A regression line's goal is to reduce the total amount of residuals.
A good residual value is what?
Check out the Car Lease Ratings section of our Lease Kit for a complete list of high-residual vehicle brands and models.
A car is probably not a good lease deal if the lease-end residual value is less than 50% of the MSRP (for a 36-month lease). 55% to 65% of MSRP would be a nice residual.

Which of the following is equivalent to 60^1/2?a. 60/2b. √60c. 1/60^2d. 1/√60
b. √60 is equivalent to 60^1/2
60^1/2 represents the square root of 60. The square root of a number is a value that when multiplied by itself, gives the original number. So in this case, √60 * √60 = 60. Therefore, the equivalent of 60^1/2 is √60.
Option a, 60/2 is not equivalent, because it is not the value that when multiplied by itself gives 60.
Option c, 1/60^2 is not equivalent, because it is not the value that when multiplied by itself gives 60.
Option d, 1/√60 is not equivalent, because it is not the value that when multiplied by itself gives 60.
It is important to note that 60^1/2 is not the same as (60^1)^1/2, the first one is finding the square root of 60 while the second one is finding the 1/2 power of 60 which is not the same thing.

What is an example of the midpoint formula?
Mid-point formula is used to determine the mid-point of a line segment. An example of the mid-point formula is discussed below.
What is the mid-point formula?
The centre of a line segment is known as the midpoint. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The formula used to find this mid-point of the line is called the mid-point formula.
[tex](x_{m},y_{m} ) =(\frac{x_{1} +x_{2} }{2} ,\frac{y_{1} +y_{2} }{2})[/tex]
where, [tex](x_{m} ,y_{m})[/tex] = mid-point coordinates
[tex](x_{1} ,y_{1})[/tex] = first point coordinates
[tex](x_{2} ,y_{2})[/tex] = second point coordinates
An example of mid-point formula is given below.
Find the mid-point of a line whose end coordinates are (3,5) and (6,10).
From the question, we can write,
[tex](x_{1} ,y_{1}) = (3,5)\\(x_{2} ,y_{2}) = (6,10)[/tex]
Then as discussed above, we can find the mid-point using the formula,
[tex](x_{m},y_{m} ) =(\frac{x_{1} +x_{2} }{2} ,\frac{y_{1} +y_{2} }{2})[/tex]
[tex]x_{m} = \frac{x_1 + x_2}{2} = \frac{3+6}{2} = 4.5[/tex]
[tex]y_{m} = \frac{y_{1} + y_{2}}{2} = \frac{5+10}{2} = 7.5[/tex]
Therefore the mid-point of the given line found using the mid-point formula is (4.5, 7.5).

The length of bc is 8. The result is obtained by using the concept of conditions for similar triangles.
How are the conditions for similar triangles?For two or more similar triangles, it has two conditions.
Corresponding angles of the triangles are equal.Corresponding sides of the triangles are in proportion to each other.A right triangle abc with altitude bd drawn to hypotenuse ac has the length of sides as follow
ac = 16dc = 4Find the length of bc!
Observe the picture of triangles in the attachment! If we drawn a perpendicular line to the hypotenuse, we'll have three similar triangles.
The corresponding sides of the two triangles are
[tex]\frac{\overline{ac}}{\overline{bc}} = \frac{\overline{bc}}{\overline{dc}} = \frac{\overline{ab}}{\overline{bd}}[/tex]
The length of bc is
[tex]({\overline{bc})^{2} = \overline{ac} \times {\overline{dc}[/tex]
[tex]({\overline{bc})^{2} = 16 \times 4[/tex]
[tex]({\overline{bc})^{2} = 64[/tex]

What is exponent?An exponent is a number or letter placed above and to the right of the base of a mathematical statement. It denotes that the base will be raised to a specific level of power. Exponents are classified into four types: positive, negative, zero, and rational. Positive exponents indicate how many times a base may be multiplied by itself. The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal 23. Keep in mind that a number raised to the power of one is itself.
