Answer:
x = -7
Step-by-step explanation:
The given equation is :
-30=5(x+1)
We need to solve the equation.
Use associative property on RHS.
-30 = 5x+5
Subtract 5 from both the sides.
-30-5 = 5x+5-5
-35 = 5x
x = -7
Hence, the value of x is -7.

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
do it step by step will it work yes
Answer:
2t + 4f = 100
t+f =42
Step-by-step explanation:
t= two point questions
f =four point questions
2t + 4f = 100
t+f =42
there are 34 two point questions and 8 four point questions
to solve multiply the second equation by -2
-2t -2f = -84
add this to 2t +4f = 100
2t + 4f = 100
-2t -2f = -84
-----------------------
2f = 16
divide by 2
f = 8
there are 8 four point questions
t+f=42
t+8 = 42
subtract 8
t = 34
there are 34 2 point questions
