Answer:
See solutions below
Step-by-step explanation:
The product of 46 and 23 2/3 is expressed as;
= 46×23 2/3
= 46 × 71/3
= (46×71)/3
= 3266/3
= 1088.67
Given a•b
If a = 5
b = 8
a•b =5•8
a•b = 40
Since null hypothesis on this data is not rejected.
<h3>Null and Alternative Hypothesis</h3>
Data;
- sample mean x1 = 240993
- population standard deviation σ1 = 25875
- sample size n1 = 35
- sample mean x2 = 249237
- population standard mean σ2 = 27110
- sample size n2 = 35
- significance level α = 0.10
H_o = μ1 = μ2
H_o = μ1 ≠ μ2
This is a two-tailed test and population standard deviation will be used.
<h3>Test Statistic</h3>
The z-stat is
The significance level is α = 0.1 and the critical value for a two-tailed test is
Since , we can assume that the null hypothesis is not rejected.

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then net force acting on the box IS 65N
<h3>What is net force?</h3>
Net force is final force acting on any object .
Here given that
A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left
So we can see it in diagram that force in upper direction and lower direction is same 100N so this force will be cancelled out
Now force in right side is 75N and in left side force is 10N
So net force = (75-10)=65N in right side
