The average speed Mr and Mrs Ozawa should drive is 62 miles per hour.
What is the difference between average and instantaneous speed?The average speed is calculated for a period of time while instantaneous speed is calculated at certain instant of time.
For instantaneous speed and average speed are equal for an object moving with constant speed.
The total distance travelled is given as 496 miles.
And, the total time taken is 8 hours.
Average speed can be calculated by taking the ratio of total distance and time as follows,
Total distance ÷ Total time
⇒ 496 ÷ 8
⇒ 62
Hence, the average speed is given as 496 miles per hour.

A) Total number of old plans = 3500 + 4700 = 8200
In the new month, the unlimited plans increased by 55%, which adds
0.55 • 3500 = 1925
unlimited plans, while the limited plans decreased by 25%, which subtracts
0.25 • 4700 = 1175
limited plans. Then
Total number of new plans = (3500 + 1925) + (4700 - 1175) = 8950
which corresponds to a percent change of
(8950 - 8200)/8200 ≈ 0.0915 = 9.15%
That is, percent change is given by
(new value - old value) / (old value)
B) The percent change is positive, so it's a percent increase.
can anyone help me pls
Answer:
88 degrees, 44 degrees
Step-by-step explanation:
The total of angles in a triangle is 180 degrees
so, 48+x+x-44=180
48-44+x+x=180
4+2x=180
-4 on both sides
2x=176
x=88
Mr. Jackson likes to play a game in which rolling a 4 on a number cube doubles your score. He wants to know the probability that he will roll a 4 exactly 3 times out of 10 rolls. Define the variables for describing a binomial probability, and identify their values in this experiment.
Answer:
Step-by-step explanation:
Binomial Probability
P(x) = n!/(n-x)!x! * p^x q^(n-x)
P(x) = probability there will be x required outcomes (here x is 3)
n = number of trials (here it is 10)
p = probability of 1 required outcome (getting a 4) on a single roll ( = 1/6).
q = probability of required outcome not occurring on a single roll.
p = 1/6
q = 1 -1/6 = 5/6
n = 10
x = 3
So the required probability
= 10!/ 7!3! (1/6)^3 (5/6)^7
= 0.155.

It takes Jada 20 minutes to walk to school. It takes Andre 80% as long to walk to school. How long does it take Andre to walk to school?
____ minutes
WARNING GIVE A DETAILED ANSWER
Time required to walk to school is, t=20 mins
Since, Andre takes 80% of time required to walk to school. Which means
Time taken by Andre = 80% of 20 minutes
t-80/100x20
t=16 minutes
Andre takes 16 minutes to walk to school.
