Answer:
At a 5% significance level we reject the Null hypothesis
Step-by-step explanation:
From the question we are told that:
Distance
Mean
Sample size
Sample mean
Standard deviation
significance level
Generally the Hypothesis is mathematically given by
Generally the equation for t test statistics is mathematically given by
Therefore P-Value from table
Therefore
At a 5% significance level we reject the Null hypothesis
Answer:
Step-by-step explanation:
3/(x-2) - 2/(x+3) = 1....multiply everything by (x-2)(x+3)
3/(x-2) * (x-2)(x+3) - 2/(x+3) * (x-2)(x+3) = 1(x-2)(x+3)
3(x+3) - 2(x-2) = 1(x-2)(x+3)
3x + 9 -2x + 4 = (x-2)(x+3)
x + 13 = x^2 + x - 6
x^2 - x + x - 6 - 13 = 0
x^2 - 19 = 0
x^2 = 19....take sq rt of both sides
sqrt(x^2) = sqrt 19
x = sqrt 19 and x = - sqrt 19 <====
500ml ⇒ 80g
2500ml ⇒ x (g)
500x=80*2500 /500
x=80*5=400 (g)

10 +20i you just multiply and look what to write simply
