Answer:
1 /4
Step-by-step explanation:
Given that:
Number of shirts in shipment = 24
Number of defective shirts in shipment = 6
The expectation about upcoming shipment which can be inferred from the information give is the probability of defect in upcoming shipments :
Probability of defect = Number of defect in shipment / total number of items in shipment
P(defect) = 6 /24 = 1 /4
Uh... I think x is -12 and y is 2
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
