Answer:
B. 2x – 1 = 13 and x = 7
Step-by-step explanation:
We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.
Option A.
2x -1 = 13 and x = 6
Using this value in the equation, we get:
2(6) -1 = 13
12 - 1 = 13
11 = 13, which is not true. Hence this option is not valid
Option B.
2x - 1 = 13 and x = 7
Using the value in the equation, we get:
2(7) - 1 =13
14 - 1 =13
13 = 13, which is true. Hence this option is valid.
Option C.
2x + 1 =13 and x = 7
Using the value in the equation, we get:
2(7) + 1 = 13
15 = 13, which is not true. So this option is not valid
Option D.
2x - 1 = 13 and x = 11
Using this value in the equation, we get:
2(11) - 1 = 13
21 = 13, which is not true. Hence this option is not valid.
An equivalent fraction? So.. the fraction has to be equivalent to 3/5, correct?
One question, what do you mean by "tenth-size strip"?
Sorry but this question isn't clear enough.
Sorry :/
[<em>We assume that each piece of apple is identical</em>]
{{{{This part for little more explanation:
There are 12C6 ways that 6 fruits can be taken from the bag
which is equal to
=12!/{(12-6)!*6!}
=(12*11*10*9*8*7*6!) / (6!*6!)
=665280 / (6*5*4*3*2*1)
=924 ways
}}}}}
Your main solution here:
Similarly there are 6C5 ways to get exactly 5 apples out of 6 fruits which is equal to,
=6! / {(6-5)! *5! }
=(6*5!) / (1!*5!)
=6 ways>>>>>>>ANSWER
NOTE: nCx=n! / [(n-x)! *x!] where n=total items and x= no of items choosen
{n is written up in the upper left of C and x is written as Subscript}
Answer:
A
Step-by-step explanation:
Temperature decreased by 12°C : (-12°C)
Expression:
12 + (-12) = 12 - 12
Answer:
<h3>The option b) is correct</h3><h3>The width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>
Increase the value of the sample mean (0.5 point) </u></h3>
Step-by-step explanation:
Given that the width of a confidence interval for one population proportion would decrease, increase, or remains the same.
<h3>
To find the result for the given data :</h3>
By definition we have that "the width for the confidence interval decreases as the sample size increases". The width of the confidence interval increases as same as the standard deviation also increases. The width increases as the confidence level increases between (0.5 towards 0.99999 - stronger).
The width of a confidence interval is affected by 3 measures. they are the value of the multiplier t* , the standard deviation s of the original data, and the sample size of n .
<h3>Therefore the width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>
Increase the value of the sample mean (0.5 point) </u></h3><h3>Therefore the option b) is correct</h3>
