If you spun the spinner 1 time, what is the probability of landing on either a white piece or a gray?
the circle in the picture has 3 gray and 5 white
there are 9 pieces in total
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
So, there are 8 pieces with color and 1 piece without the wanted color.
The equation for finding the probability is: [tex]\frac{sum of terms }{number of terms }[/tex]
Therefore: 3 + 5 = 8 and 9 pieces in total
so the correct answer should be 8/9

(20 POINTS) One side of a trapezoid is extended and the dotted line forms a right angle with the extended line.
Answer: p = 115* (degrees)
Explanation:What we know:
The trapezoid forms a right triangleThe right triangle has the angles 25*, 90*, and an unknownThe internal angles of a triangle add up to 180*The unknown value p is a supplementary angle to the right triangle's unknown angleHow to solve:
By finding the degree of the 3rd angle in the right triangle, we can use the rules of supplementary angles to find the value of p.
We will use D to represent the total amount of degrees, which will equal 180*. X will represent an unknown angle. An asterisk represents the degree symbol.
Process:Missing right triangle angle
Set up equation D = 25 + 90 + x
Substitute 180 = 25 + 90 + x
Simplify 180 = 115 + x
Isolate variable -115 -115
Solution 65* = x
Value of p using supplementary angles
Set up equation D = x + p
Substitute 180 = 65 + p
Isolate variable -65 -65
Solution 115* = p
Answer: p = 115*Check:
We can do a check based on estimation. Assuming that the trapezoid and triangle form a box with all 90* corners and that p = 115*, then adding p and all of the other trapezoid angles should result in 360*
Firstly, we need the values of these 4 angles.
The first angle, labeled p, should be 115*. If our equation is untrue, then this value will fail the check.
The second angle will be the one at the bottom-left, which is 90* according to our box statement.
The third angle is the one located at the bottom-right, which is also 90* from the box statement.
The fourth angle is not 90* or 115*, but we can solve its value.
Because we have stated that the right triangle and trapezoid form a box with 4 90* corners, the sum of the fourth angle and the 25* from the right triangle must form a right angle. Let's find the value:
D = 25 + x
90 = 25 + x
(90 = 25 + x) - 25
65* = x
Therefore, the fourth angle has 65*
Now, adding the degrees from all 4 angles should result in a total of 360*. If it does, then our value of p = 115* will pass the check.
D = 90 + 90 + p + x
360 = 90 +90 + 115 + 65
360 = 180 + 180
360 = 360
Therefore, p = 115*
Answer:
C
Step-by-step explanation:
A and B are out because we can already tell that 65 and 75 are smaller than the 90 degrees whichs this angle is even higher than.If you see or use a protrater you can see it seems more likely to 115 because 155 would be much more open.

Martin tracked the amount of water he drank for an entire week. The bar graph shown here displays the information about his water consumption. What is the mode of the daily data A)8 B) 10 C)12 D)14
Answer:
c)12
Step-by-step explanation:
since on the bar graph 12 occurs the most that is the mode so hope this helps!
The mode of the daily data is 12 cups.
How to identify skewed graph?A skewed distribution is a distribution having bias on one of the two sides (either left or right).
It is like leaning mountain on one side (left or right).
A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph. This graph usually has mean < median < mode.
A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph. This graph usually has:
Mode < median < mean.
We are given that;
The bar graph show 8cups on monday, 12 cups on tuesday, 10 cups on wednesday, 16 cups on thrusday, 12 cups on friday, 14 cups on saturday and 18 cups on sunday.
Now,
The mode of a set of data is the value that occurs most frequently.
Looking at the bar graph, we can see that the values 8, 10, 12, 14, 16, and 18 all occur once, but only one value occurs more than once, which is 12 cups on Tuesday and Friday.
Therefore, by skewed distribution the answer will be 12.
