Answer:
12x + 15y=34
x=34/12 = 17/6
y=34/15
____________________
-6x + 5y=3
x=3/-6 = 1/-2
y= 3/5
Step-by-step explanation:
The possible outcomes for the coin is 2 out of 1 since a coin has 2 sides the coin may only land on 1 side but the chances are between both sides having a 50/50 chance to land on either side.
Answer: t = 10
Step-by-step explanation:m
Given that; n₁ = 10, n₂ = 10
ж₁ = 50, ж₂ = 30
Sˣ₁ = 20, Sˣ₂ = 20
Now using TEST STATISTICS
t = (ж₁ - ж₂) / √ ( Sˣ₁/n₁ + Sˣ₂/n₂ )
so we substitute our figures
t = ( 50 - 30 ) / √ ( 20/10 + 20/10 )
t = 20 / √4
t = 10
Step-by-step explanation:
65=(4x+1)
65=4x+1)
65-1=4x
64=4x
64/4=4x/4
x=16
