Answer:
Well there are many different ways to find 8x5=40 to 8x6=__
You could add 8 to 40 and get 48.
or you could draw pictures to represent the 48.
8x6=48
0.31 rounded to the nearest tenth would be 0.3

Answer: ゼロ
Step-by-step explanation:
Answer: The value of test statistic is 2.442.
Step-by-step explanation:
Since we have given that
n = 238
Sample mean = 23.2 minutes
Standard deviation = 20.26 minutes
Hypothesis :
So, the test statistic value would be
Hence, the value of test statistic is 2.442.
4/(x+1) = 3/x + 1/15
Should we make common denominators with everything, we get
4*15*x / [15x(x+1)] = 3*15*(x+1)/[15x(x+1)] + x(x+1)/[15x(x+1)]
Multiply both sides of the equation by the denominator to cancel them
60x = 45(x+1) + x(x+1)
60x = 45x + 45 + x^2 + x
x^2 - 14x + 45 = 0
(x-9)(x-5) = 0
The answer to this question is that the solutions are x=9 and x=5.
