Answer: A)1/2
Step-by-step explanation: m = y2-y1/x2-x1
I will use the values (1,2) and (3,3) from the table
1=x1, 2=y1, 3=x2, 3=y2
m = 3-2/3-1
m=1/2
Answer:
The volume of figure is 310.86 cm³
Step-by-step explanation:
First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :
Cone,




Cylinder,




Next, you have to add up both volumes as the figure are made from cone and cylinder :


Answer:
Given:
mean, u = 6.2
sample size, n = 180
Sample mean, X' = 6.3
s.d
= 0.9
Significance level = 0.05
The null and alternative hypothesis will be:
H0 : u = 6.2
H1 : u > 6.2
Degree of freedom = 180 - 1 = 179
Using t table, the t critical value,
t> t(0.05, 179) = 1.6534
The test statistic:
Since the test statistic(t calculated value) 1.4907 < t critical value (1.6534), we fail to reject the null hypothesis H0.
If the question is the best way to factor it I would say: (x-4)(x-3)(x+5)
