D. Should be the correct answer
Answer:
f(3) = 4(3)-2 = 12-2 = 10
Step-by-step explanation:
By comparing f(3) and f(x), you can see that it is basically replacing the x in the equation with the value of 3.
Answer:
x can be any value
Step-by-step explanation:
x can be any value and its output is always a constant 8.
Answer: P(x > - 0.23) = 0.41
Step-by-step explanation:
Since we are assuming that the readings at freezing on a batch of thermometers are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the readings at freezing on a batch of thermometers.
µ = mean temperature reading
σ = standard deviation
From the information given,
µ = 0°C
σ = 1.00°C
the probability of obtaining a reading less than -0.23°C is expressed as
P(x > - 0.23)
For x = - 0.23
z = (- 0.23 - 0)/1 = - 0.23
Looking at the normal distribution table, the probability corresponding to the z score is 0.41
