Substitute the x-value and see if you get the corresponding y-value. The corresponding y-value an x-value of 3 in this equation should be
Since the coordinate (3,32) does not represent that, it is a false solution
Step-by-step explanation:
Hope this is correct
HAVE A GOOD DAY!
Answer:
(c)
(b) The probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c) The probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Step-by-step explanation:
The random variable <em>X</em> follows a Uniform (25, 35).
(a)
The probability density function of an Uniform distribution is:
Then the probability density function of the random variable <em>X</em> is:
(b)
Compute the value of P (X > 33) as follows:
Thus, the probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c)
Compute the mean of <em>X</em> as follows:
Compute the probability that cooking or preparation time is within 2 mins of the mean time as follows:
Thus, the probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Answer:
B. (0,6)
Step-by-step explanation:
To solve this question, you'll need to figure out what the final point is after reflecting each point. A quick way to figure this out is by multiplying (-1) to the x-coordinate.
When you reflect A. (2,0) over the y-axis, the point becomes (-2,0).
When you reflect C. (3,3) over the y-axis, the point becomes (-3,3).
When you reflect D. (5,5) over the y-axis, the point becomes (-5,5).
The only answer that does not change location is B. (0,6) as it stays at (0,6). If you multiply 0 by any number, it will always stay 0.
Multiplying the x-coordinate by (-1) to find the reflection point only works if you are reflecting it over the y-axis. You would multiple the y-coordinate by (-1) if you were reflecting over the x-axis.
Answer:
A. 4r=v
Step-by-step explanation:
It says that she ate 4 times as many as Reagen and r represents the number that Reagen at so it would be 4r. While v represents how many Olivia ate which is 4r so 4r = v.
