Answer: 0.6 cm
Step-by-step explanation:
Given : Over the past 4 years, Grandpa Ernie's height decreased by a total of 2.4 cm.
If the height is decreased by the same amount each year.
Then, the change in Grandpa Ernie's height each year will be =
Total decrease in height ÷ 4
= 2.4 cm ÷ 4 = 0.6 cm
Hence, the change in Grandpa Ernie's height each year = 0.6 cm
Two million, nine hundred forty seven
2,000,000+900+40+7
I really need help on apex in physics can someone help
If she read 21/40, this means that she hasn’t read 19 of the 40 chapters.
You can divide 19/40 to get the decimal
19/40=0.475
Hope this helps!! :)
Answer:
22.51% probability that fewer than 4 of them use their smartphones in meetings or classes.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they use their smartphones in meetings or classes, or they do not. The probability of an adult using their phone is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening
47% use them in meetings or classes.
This means that
10 adult smartphone users are randomly selected
This means that
Find the probability that fewer than 4 of them use their smartphones in meetings or classes.
In which
22.51% probability that fewer than 4 of them use their smartphones in meetings or classes.
