<span>f(x) = 4x and g(x) = 3x
</span><span> (fog)(x)
</span>you need take value of g(x), 3x, and put 3x instead of x in f(x) function
(fog)(x)=4*(3x)=12x
Answer: the answer is not in the option (-2,0.5)
Step-by-step explanation:
First case assume x=0, y=-2
Y=0, x=0.5
Answer:
68.268%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $1900
σ is the population standard deviation = $200
For x = $1700
z = $1700 - $1900/$200
z = -1
Probability value from Z-Table:
P(x= 1700) = 0.15866
For x = $2100
z = $2100 - $1900/$200
= 1
Probability value from Z-Table:
P(x = 2100) = 0.84134
The probabilty of the population that has a rent price between $1700 and $2100
P(x = 2100) - P(x = 1700)
0.84134 - 0.15866
= 0.68268
Converting to percentage
= 0.68268 × 100%
= 68.268%
The percentage of the population that has a rent price between $1700 and $2100 is 68.268%
Answer:
P(B) = 0.6
Step-by-step explanation:
P(A and B) = P(A) * P(B)
0.12 = 0.2 * P(B)
P(B) = 0.6
P(A or B) = P(A) + P(B) - P(A and B)
0.68 = 0.2 + P(B) - (0.12)
P(B) = 0.6
