Here is the answer to the given problem. So, what Christina wants to find out is the sum of the length after 10 throws given that in each throw, it retracts 70% of the original length. So to continue the given data, here are the results:
4: 1.029
5: 0.7203
6: 0.50421
7: 0.352947
8: 0.2470629
9: 0.17294403
10: 0.12106082
Since she wants to find the sum of the length after 10 throws, we are just going to add the lengths above. So the answer would be this: 9.71752475. To round this off to the nearest hundredth, the answer would be 9.72. Hope this helps.
Simple, what you're basically doing is simplifying,
well, you have 3x and you have
12/3=4
and you can "cancel" out an x, making your answer,
.
Answer:
(x-1)^2 + y^2 = 25
Step-by-step explanation:
center C ( ( xA + xB)/2 , (yA+yB)/2 ) = ( 1 , 0)
AB = 10
radius = AB / 2 = 5
equation formula: (x - xC)^2 + (y-yC)^2 = radius^2
Hence:
(x-1)^2 + y^2 = 25
Answer:x=143
Step-by-step explanation: set 128=X-15 add 15 to both sides
Answer:(c)
Step-by-step explanation:
Given : In a hypothesis testing the null hypothesis has been rejected when the alternative hypothesis has been true.
Find : to find that the given decision is create type I error , type II error or right decision has been taken
Step by step :
In hypothesis testing there are 2 types of error.
(1)Type I error :- if the null hypothesis is rejected when it is true, is known has Type I error .
(2)Type II error:- if the null hypothesis is accepted when alternative hypothesis is true, is known as type II error.
Since here null hypothesis has been rejected when alternative hypothesis has been true,i.e., the correct decision has been made
Hence option (c) is correct.
