If you mean equal payments each week like 30x = 2730 then it would be $91 per week for the 30 weeks to pay it
Answer:
(1) The correct option is (A).
(2) The probability that Aadi will get Tails is .
Step-by-step explanation:
It is provided that:
- Eric throws a biased coin 10 times. He gets 3 tails.
- Sue throw the same coin 50 times. She gets 20 tails.
The probability of tail in both cases is:
(1)
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the proportion of tails.
Then according to the Central limit theorem, Sue's estimate is best because she throws it <em>n = </em>50 > 30 times.
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
Thus, the probability that Aadi will get Tails is .
Answer:
24.4
Step-by-step explanation:
since 39% of 40 is 15.6 you have to subtract 15.6 from 40 to get 24.4
Step-by-step explanation:
10=x
7x=70
-10+5x=40
that is my math
Answer:
D: -75 the balloon is descending at a rate of 75ft per minute
Step-by-step explanation:
To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values
450-300=150
0-2=-2
150/-2 = -75
that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.
Hope this helps :)
