<u>Given</u>:
The graph of 
shows the value of a rare coin in year t.
We need to determine the meaning of the y - intercept.
<u>Meaning of the y - intercept:</u>
Here, t represents the x - axis and f(t) represents the y - axis.
The value of y - intercept is the value of y when x = 0.
Hence, the the value of f(t) can be determined by substituting t = 0 in the function
Thus, we have;
Thus, the value of the y - intercept is 4.
The y - intercept represents the value of the rare coin in year 0.
Therefore, the meaning of the y - intercept is "When it was purchased (year 0), the coin was worth $4".
Hence, Option B is the correct answer.
When we want to determine the relative position of two lines, the first thing we can do is to write them in the same form.
We can use the form y=mx+k, where m is the slope.
the given lines are lines in plane. The "skew" case cannot be considered.
i) if 2 lines have same slope, but different k, then they are parallel,
ii) if 2 lines have equal slope (m) and k, then they are coinciding
iii) if the multiplication of their slopes is -1, then they are perpendicular
iv) if the slopes are not equal, and their multiplication is not -1, then the lines are intersecting
2.
4x+2y=8
2y=-4x+8, divide by 2
y=-2x+4
the other line is y=2x+4
-2 and 2 are not the same so the lines are neither parallel, nor intersecting.
-2 * 2 is not equal to -1, so the lines are neither perpendicular.
The lines are intersecting.
Answer:
wow
Step-by-step explanation:
To add
<span> 346
421
+ 152
Starting woth the ones place 6 + 1 + 2 = 9, because, the sum of the digits in the ones place is not upto 10, we will not regroup the ones place.
Thus, the answer to 13a is NO
Since, we did not regroup the ones place, there is no regrouped tens to add, thus the answer to 13b is NO.
Next, for the tens place, 4 + 2 + 5 = 11, because the sum of the digits in the ones place is upto 10, we regroup the tens place.
Thus, the answer to 13c is YES.
</span><span>Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13b is YES.
Finally, for the hundred place, 1 + 3 + 4 + 1 = 9
Therefore, the sum of

Answer: Skewed left, no outlier
Step-by-step explanation: You use the IQR and quartile 1&3 to find the number that defines an outlier. And for this one there are none
