Answer:
Three times the difference of two times a number and five is equal to 24, what is x?
Step-by-step explanation:
To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.
Answer:
<u>A. Mean = 402.5</u>
<u>B. Variance = 77,556.25</u>
<u>C. Standard Deviation = 278.49</u>
Step-by-step explanation:
Let's calculate the mean, variance and standard deviation of the set of numbers given:
A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 =<u> 402.5</u>
B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =<u> </u><u>77,556.25</u>
C. Standard Deviation = √Variance = √77,556.25 =<u> 278.49</u>
Ouch, kinda crippled w/o answer choices.
But with my calculating, i've made it out to be <span>92.07 %
Please do respond & rate based on my accuracy.

Answer: 0.1122
Step-by-step explanation:
Let A denotes the event that it snows in Greenland.
Then A' denotes the event that it does not snow in Greenland.
Let G be the event that glaciers grows.
Given : Suppose that it snows in Greenland an average of once every 27 days.
i.e.
Then,
Also, P(G|A)=0.23 and P(G|A')=0.07
By Bayes theorem , we have
Hence, the probability that it is snowing in Greenland when glaciers are growing= 0.1122
Eight and eighty-four hundredths in standard decimal form is 8.84 because 8 is the whole number, the 8 on the right of the decimal is in the tenths place, and 4 is in the hundredths place. :)
