the product of a decimal greater than 1 and a whole number is always greater than the whole number because we are scaling the whole number.
Answer:
1/8, 0.0625
, or 6.25%
Step-by-step explanation:
50% of the cars are painted white.
1/2 * 1/2 = 1/4 * 1/4 = 1/8
Probability of A occuring 4 time(s) = 0.54 = 0.0625
Probability of A NOT occuring = (1 - 0.5)4 = 0.0625
Probability of A occuring = 1 - (1 - 0.5)4 = 0.9375
Answer: 1080 degrees
Step-by-step explanation:
X²-9x=36
minus 36 both sides
x²-9x-36=0
what 2 numbers multiply to -36 and add to -9
-12 and 3
(x-12)(x+3)=0
set to zero
x-12=0
x=12
x+3=0
x=-3
the number is either -3 or 12
Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k = 
= 
, thus
y = x ← equation of variation
When x = 7, then
y = × 7 =
