If the question is 418/19, then the answer is 22
Answer:
2.1275 is 2.12747677748 rounded to the nearest ten-thousandth.
Step-by-step explanation:
Since the hundred-thousandth place is 5 or above, we would round the ten-thousandths place up. THis makes the number 2.1275.
Answer:
A
Step-by-step explanation:
Each domain value (x-value) of a function has exactly one range value (y-value).
A function can have two or more domain (x-value) having the same range (y-value)
Graph A shows the different domain value (x-values) having exactly one range value (y-value). No x-value has two different y-values.
Therefore, graph A is a function.
Answer:
0.21186
Step-by-step explanation:
We solve the above question using the z score formula.
z = (x-μ)/σ, where
x is the raw score = 3100g
μ is the population mean = 3500g
σ is the population standard deviation = 500g
z = 3100 - 3500/500
z = -0.8
Probability value from Z-Table:
P(x<3100) = 0.21186
The probability that a baby is born that weighs less than 3100g is 0.21186
