A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
Then answer you seek is 133.
Answer:
The probability that a household has at least one of these appliances is 0.95
Step-by-step explanation:
Percentage of households having radios P(R) = 75% = 0.75
Percentage of households having electric irons P(I) = 65% = 0.65
Percentage of households having electric toasters P(T) = 55% = 0.55
Percentage of household having iron and radio P(I∩R) = 50% = 0.5
Percentage of household having radios and toasters P(R∩T) = 40% = 0.40
Percentage of household having iron and toasters P(I∩T) = 30% = 0.30
Percentage of household having all three P(I∩R∩T) = 20% = 0.20
Probability of households having at least one of the appliance can be calculated using the rule:
P(at least one of the three) = P(R) +P(I) + P(T) - P(I∩R) - P(R∩T) - P(I∩T) + P(I∩R∩T)
P(at least one of the three)=0.75 + 0.65 + 0.55 - 0.50 - 0.40 - 0.30 + 0.20 P(at least one of the three) = 0.95
The probability that a household has at least one of these appliances is 0.95
Answer:
my brain suddenly is dead and has stopped progressing
Step-by-step explanation:
Answer:
1. 2x + 3y =22
y=4
C. (5,4)
2. y=0
-5x - 2y = -15
B. (3,0)
Step-by-step explanation:
2x+(3)(4)=22
Step 1: Simplify both sides of the equation.
2x+12=22
Step 2: Subtract 12 from both sides.
2x+12−12=22−12
2x=10
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
====================================================================
−5x−(2)(0)=−15
Step 1: Simplify both sides of the equation.
−5x−(2)(0)=−15
−5x+0=−15
(−5x)+(0)=−15(Combine Like Terms)
−5x=−15
−5x=−15
Step 2: Divide both sides by -5.
−5x/−5 = −15/−5
x=3
