How far does a bus travel in 2.5 hours at 65 mph?
Answers
distance = 65 mi / h * 2.5 h = 162.5 miles
Answer:
Distance traveled = 162.5 miles
Step-by-step explanation:
a bus travel in 2.5 hours at 65 mph
The time taken to travel is 2.5 hours
Speed of the bus is 65mph
To find the distance we use formula
Distance = speed * time
speed = 65
time = 2.5
Distance = 65* 2.5 = 162.5 miles
Distance traveled = 162.5 miles

Answer:
The area of B is 8 cm²
Step-by-step explanation:
From the diagram, we can tell that the scale factor is 2 because the length of A is 6 cm and the length of B is 12 cm so the scale factor is 2. Since diagram A's area is 4 cm², all we need to do is multiply the diagram A's area by 2. That gives diagram B's area which is 8 cm²

Answer:
170.
Step-by-step explanation:
We have that A = W*L where A= Area, W= width, L=length and that W = 13+L. So,
A = (13+L)*L
1764 = 13L + L^2
L^2 + 13L - 1764 = 0.
We use the general formula in the image where a=1, b=13 and c= -1764.
, this result will be negative and the problem is about length so it doesn't apply for this problem. We use L1= 36.
Then, L=36, W = 13 + 36 = 49. Therefore, the perimeter is 2L+2W = 72+98=170.
Here in France we call length the greater side of a rectangle.
So:
Let a the greater side
b the shortest
a=b+13
a*b=1764
==>b*(b+13)=1764
==>b²+13b-1764=0
==>b=(-13-85)/2 to exclude
or (b=(-13+85)/2=36 and a=36+13=49)
P=2(a+b)=2(36+49)=170 (m)
Proof:
49-36=13
36*49=1764

By using relation between standard deviation and variance we got that sample with 0.75 variance has a standard deviation that is greater than the variance
What is standard deviation?
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value
Here we have to find a sample with standard deviation greater than the variance.
We know that Standard deviation is the square root of the variance so if we want a sample with greater Standard deviation than the variance then it's variance should be less than one as we know that if
And here given variances are
2.25, 1.75,0.75 and 1.25
Hence 0.75 is correct answer
By using relation between standard deviation and variance we got that sample with 0.75 variance has a standard deviation that is greater than the variance

Hence, for the standard variation to be greater than the variance, the variance must be between 0 and 1.
Answer: C [0.75]
