Answer:
6x^7.
Step-by-step explanation:
The exponent property for this would be that
x^a * x^b = x^a + b.
So x^2 * x^5 = x^2 + 5 or x^7.
The other part is just multiplying the coefficients 3 and 2, which is 6.
Put these together and you get your answer 6x^7.
Answer:
Yes
We fail to reject the alternative hypothesis Hₐ < 30, that is the average age of students is less than 30
Step-by-step explanation:
Yes because, there is an average age of a sample which can be tested against a null hypotheses
We put
Null hypothesis as H₀ = 30
The alternative hypothesis as Hₐ < 30
We have

With
= 29
μ = 30
σ = 5.2
n = 65
α = 10%
We have
Here we have z = -1.55 and critical z = -1.28
Which gives a critical
of 29.83 with the probability P = 0.061 < 0.1 Hence we reject the null hypothesis as there is sufficient evidence to suggest that the average age is less than 30 years.
