In order to find b1 from your formula stated we need to do few calculations
A=hb1+hb2, as you wee I multiply h with both bases( b1 and b2)
I will subtract hb2 from both sides
hb1=A-hb2
now I will divide my new expression by h
b1=(A-hb2)/h

Solve like a regular algebraic expression A= h(b1+b2) divide both sides by h A/h= b1+b2 subtract b2 from both sides A/h-b2= b1 b1= A/h-b2 hope this helps

Find the product. Write your answer in exponential form. <br><br> 5^5•5
Karo-lina-s [1.5K]

Answer:

  5^6

Step-by-step explanation:

5^5×5 = 5^5×5^1 = 5^(5+1) = 5^6

_____

This may become more obvious if you remember that an exponent signifies repeated multiplication:

  (5^5)·(5) = (5·5·5·5·5)·(5) = 5·5·5·5·5·5 = 5^6

For an independent-measures ANOVA comparing two treatments with a sample of n = 10 in each treatment, what is the critical value
trapecia [35]

Answer:

critical value is 4.41

Step-by-step explanation:

Given data

n = 10

α = .05

to find out

the critical value

solution

first we calculate degree of freedom i.e

degree of freedom = n -1

degree of freedom = 10 - 1

degree of freedom = 9

and

degree of freedom 2 =( n -1 ) 2

degree of freedom 2 =( 10 -1 ) 2

degree of freedom 2 = 18

so for degree of freedom 9 and degree of freedom 2 is 18  and α = .05

critical value is 4.41
