948/10 = 94.8^3 = 851,971.392
Answer:
x = 1.2...
Step-by-step explanation:
Start with the given equation and isolate the variable.
6.2x + 1.2 = 8.9
Subtract 1.2 from each side:
6.2x = 7.7
Divide each side by 6.2:
x = 1.2...
X³ - 12x² + 35x
x(x² - 12x + 35)
x(x-5)(x-7)
Answer:
p value = 0.039
t = - 2.169
Step-by-step explanation:
Applying the null and alternate hypothesis

using excel worksheet to calculate for ( t and p )
t = -2.169
p = 0.039
from the results obtained
The conclusion is affected by the significance level because : 0.1 < p > 0.01
so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while
if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01
attached is the excel solution
