The correct answer is B.
In order to prove which of the function rules provided is the one corresponding to the schedule represented by the table, the different y-values need to be sustituted in the function rules. <u>Only the correct function rule will yield the corresponding x-value. </u>
<u>Let's prove that option B is the correct one</u>
FUNCTION B y= 5x - 14
- If x= -4 --> substituting: 5(-4) - 14= -20 - 14= -34 therefore, y= -34 <u>CORRECT</u>
- If x= -1 --> 5(-1)-14 = -5 - 14= -19 therefore y= -19 <u>CORRECT</u>
- If x= 2 --> 5(2) - 14= 10-14= -4, therefore y= -4 C<u>ORRECT</u>
- If x= 4 --> 5(4)-14= 20-14= 6, therefore y=6<u> CORRECT</u>
- If x= 7 --> 5(7) -14= 35-14= 21, therefore y=21 <u>CORRECT</u>
Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205
Answer:
The girls and boys heights are equal and none are shorter or taller.
You get this answer from identifying the numbers, seeing if there is any number that is larger or shorter than 40-60.
Hope this helped!
