<u>Answer:</u>
42%
<u>Step-by-step explanation:</u>
We know that the number of times red side is faced up = 21; and
the total number of times colored chip is thrown = 50
Frequency of red side = (No of times red side is faced up / Total number of times colored chip is thrown) * 100%
Frequency of red side = (21 / 50) * 100% = 0.42 * 100 = 42%
Therefore, the relative frequency of the chip landing with the red side facing up is 42%.
Please send more context as of the "green numbers".
For the multiplication,
i 49 x 10 = 490
490 ÷ 10 = 49
ii 2.3 <span>÷ 10 = 0.23
0.23 x 10 = 2.3
iii 0.034 x 1000 = 34
34 </span><span>÷ 1000 = 0.034
iv 876 </span><span>÷ 100 = 8.76
8.76 x 100 = 876
Hope this helps :)</span>
Answer:
A. y-axis only
Step-by-step explanation:
We have the graph of as given below.
It can be seen that passes through the points (0,0), (4,0) and (6,0).
Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.
Hence, the axis of symmetry of is the y-axis only.
Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15
If 1 inch is .25 miles then all you have to do is multiply .25 miles by 5 inches and u get 1.25 miles.
