Answer:
It is given that a car traveling at 23 mi/h accelerates to 46 mi/h in 5 seconds.
This means that in 5 seconds it's speed continuously increases to reach 46 mi/h from 23 mi/h.
It maintains that speed for 5 seconds and then slows to a stop in 5 seconds.
This means that the speed of the car is constant i.e. 46 mi/h i.e. the graph is a straight horizontal line parallel to the time axis.
And then it decreases to reach 0 mi/h.
Answer:
(C) 4
Step-by-step explanation:
I am going to solve this by trial and error:
(A) 1
Is: 
?
So 1 is not the digit of N.
(B) 2
Is: 
?
So 2 is not the digit of N.
(C) 4
Is: 
?
Correct, so the answer is c.
(D) 5
(E) 6
Answer:
1/5
Step-by-step explanation:
Since the surveys are chosen with replacement (the first one is replaced before the second is chosen), the events are independent. This means that the probability of both together is the product of each event's probability.
The probability of choosing a survey that indicates 4 children in the family is 8/60, since there are 8 surveys with 4 children out of a total of (9+18+22+8+3) = 60 surveys.
The probability of choosing a survey that indicates 1 child is 9/60, since there are 9 surveys with 1 child out of a total of 60.
Together this gives us
8/60(9/60) = 72/360 = 1/5
You’ll pay $775 since 25 pairs were $625
The interquartile range is from Q1 to Q3 and to get this you have to subtract Q2 by Q3. The 10 units represent that only 10 units are fit in the given range.
