Answer:
1. Answer is 160 m
2. Answer is 1500 m²
Step-by-step explanation:
perimeter = 2(l+b)
which implies 2( 28.3 + 53.7) m = 160 m
Area is length× breadth
which implies 28.3× 53.7 = 1500 m²

Answer:
<h2>5</h2>
Step-by-step explanation:
Given the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;
∠AOC = ∠BOC+∠AOB
Substituting the given values into the expression, we will have;
21 = x+3+4x-7
collect the like terms
21 = x+4x+3-7
21 = 5x-4
Add 4 to both sides
21+4 = 5x-4+4
25 = 5x
Divide both sides by 5
5x/5 = 25/5
<em>x = 5</em>
<em></em>
<em>Hence the value of x is 5</em>
Answer:
a) Repeated measure ANOVA techniques you can use along with the Hypothesis Testing, and your Null Hypothesis will be that there is no effect between the rat pups you have and the new available as claimed by the salesman.
b) In this part you can use ANOVA for measuring the variance produced by all three factors and Null Hypothesis will be that there is no effect of all these factors, if we get the pvalue less than 0.05 then our Alternate hypothesis will be that the factors has some effect.
c) In this type of problem where we have more than 3 Nos of Independent Variable we have to use Linear Regression to check our hypothesis that whether there is significant variance exist between different variables or not.
d) Okay you can use paired sample t-test in this question since you have only two brands to test and comparing the means over the hypothesis will lead you to the best solution.
