If the mean is 50 and the standard division is 10 what is the probability that a randomly selected item is between 20 and 60
Answer:
84%
Step-by-step explanation:
Okay, I want to work out the chance that was between 20 and 60. Other words will find the area. 20 2 60 this area here. And the answer is because the area under the curve is always one in total. So the workout p of 20, less than x. Less than 60 here. I need a calculator And the input on the TI 84 plus is as follows, you press the second blue button, second, followed by vars V A R S, that's by the arrow keys on the right, that brings up the menu for distributions and what you want is normal C D E F Number two on the list, so normal C D E F. You press enter and it was a lower upper, lower is 20 upper is 60. The mean is 50 and the standard deviation is 10, There's a four number input. So 20 for lower 60 for upper 50 for the mean And 10 for the s. d. Standard deviation so, and then paste that onto the screen and press enter and we get 0.83999. And hear what they want. There's a percent to have some more places.
Therefore, it will be 84.00 percent. The two decimal places
in the figure, p||q. On a recent math test, Jacob incorrectly listed the value of w as 101.
Find the value of w.
What mistake did Jacob likely make?
Answer:
x = 79
Step-by-step explanation:
Part A:
It's stated that line p and line q are parallel, if it is so then the angle represented with w and the angle with measure 79 are alternate and their measure is equal to each other:
Part B:
Jacob likely thought angle represented with W and the angle with the measure 101 are alternate so he made a mistake and found wrong result.
In the diagram, A||B and B||C. Find the values of X.
Answer:
31
Step-by-step explanation:
3x + 12 and 105 are alternate exterior angles because A || B and B || C.
If the two or more lines are parallel, then the alternate exterior angles are equal.
3x + 12 = 105
Substract 12 on both sides,
3x = 105 - 12
3x = 93
Divide 3 on both sides,
x = 93 / 3
x = 31

per hour. Which one?
A. -12i
B. -12j
C. 12i
D. 12j
E. 12i + 12j
Answer:
B
Explanation:
The north is opposite to the south
So the vector [tex]j[/tex] represents 1 mile per hour south.
Maria is jogging south at 12 miles per hour.
Therefore, the vectors [tex]12j[/tex] represents Maria's velocity. The correct answer is B.
The vector used to represent the position of Maria is -12j.
What is Vector?A measurement with a magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity. A vector does not have position, while having magnitude and direction.
Given:
vector i represents 1 mile per hour east
and, vector j represents 1 mile per hour north
Now, the position of north is opposite to south
Now, Maria is jogging south at 12 miles per hour.
So, the vector used to represent the position of Maria is -12j.

Which equation represents the slope-intercept form of the line below
Answer:
[tex]y = \frac{1}{2}x + 8[/tex]
Step-by-step explanation:
The general slope-intercept equation is: y = mx + b.
In this equation, "m" is equal to the slope and "b" is equal to the y-intercept.
Since the slope is "1/2", then this is the "m" value.
Since the line passes the y-axis at "8" when x = 0, then "b" must be "8".
Therefore, the equation of the function in slope-intercept form is [tex]y = \frac{1}{2}x + 8[/tex].

Find the equation of a line that passes through the points (2,5) and (2,12)
We know the following:
[tex]\text{Slope formula} = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Note: Slopes can only be determined if the lines are not vertical.
Since the x-coordinate of the points that pass through the line are the same, when the points are substituted in the slope formula, the slope will result in "undefined" (Work shown below).
[tex]\text{Slope formula} = \dfrac{12 - 5}{2 - 2}[/tex]
[tex]\text{Slope formula} = \dfrac{7}{0} = \text{unde}\text{fined} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Any non-number divided by 0 is unde}\text{fined}][/tex]
Now, let's see if the vertical line will intersect the x-axis or a y-axis.
Determining if the line will intersect the x or y-axisTo determine if the vertical line will intersect the x or y-axis, we must look for the intersection of the line on the x or y-axis. The vertical line will be parallel to the y-axis and will intersect the x-axis.
Therefore, the line will intersect the x-axis.
Replacing values in an equation:Since the line does not intersect the y-axis, the equation of the line on the left-hand side will have an x-variable.
⇒ x = ?
The x-intercept will be substituted on the right-hand side of the equation. Since the line that passes through the two points [(2,5) and (2,12)] have the "2" as their x-coordinates, the x-intercept will also be 2. Therefore,
⇒ x = 2

1. You have to find the gradient / slope from y = 5x + 20
y = 5x + 20
y = mx + c
With using a general form, we known that the gradient of the line is 5.
2. Use the formula "[tex]y - y_1 = m.(x - x_1)[/tex]" to find the line.
[tex]y - y_1 = m.(x - x_1)[/tex]
[tex]y - 10 = 5.(x - 0)[/tex]
[tex]y = 5x - 0 + 10[/tex]
[tex]y = 5x + 10[/tex]
Answer:
y = 5x + 10.
Step-by-step explanation:
Y = 5x + 20
The gradient m = 5
So the line parallel to it has a gradient of 5 also.
Using the point slope form of straight line:
y - y1 = m(x - x1)
Here, m = 5, x1 = 0 and y1 = 10:
y - 10 = 5(x - 0)
y - 10 = 5x
y = 5x + 10.
