Answer:
a
The null hypothesis is 
The alternative hypothesis is 
b
c
d
The decision rule is
Reject the null hypothesis
e
There is sufficient evidence to support the researchers claim
Step-by-step explanation:
From the question we are told that
The first sample size is 
The sample variance for elementary school is 
The second sample size is 
The sample variance for the secondary school is 
The significance level is 
The null hypothesis is
The alternative hypothesis is
Generally from the F statistics table the critical value of at first and second degree of freedom 
and 
is
Generally the test statistics is mathematically represented as
=> 
=>
Generally from the value obtained we see that 
Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to support the researchers claim

Answer:
see explanation
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
= a + (n - 1)d
where a is the first term and d the common difference
d = 25 - 20 = 30 - 25 = 5 and a = 20, hence
= 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula
Answer:
4p+9=
(first start with multiple or division division from right to left then with addition from right to left)
4*4+9=
16+9=25
Given:
The table of values of an exponential function.
To find:
The missing values in the exponential function.
Solution:
The general exponential function is defined as:
...(i)
Where, a is the initial value and b is the growth factor.
First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).
...(ii)
Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).
...(iii)
Dividing (iii) by (ii), we get
Putting 
in (ii), we get
Putting 
in (i), we get
The required exponential function for the given table of values is . So, the missing values are 2 and x, where 2 is in the base and x is in the power.
