Answer:
Top left, bottom left, & bottom right are functions
Step-by-step explanation:
To be considered a function, you must have no repeating X variable. Column A represents X, Column B represents Y.
The top left and bottom left diagrams show the A numbers going to one single B number, there is no A number with two lines going to a B number.
The bottom right may have two lines going to a B number, but there is no A number with two lines, still making it a complete function.
Now for top right, in the A column, variable d clearly has 2 lines making it not a function.
Hope this makes sense! :)
Hello,
The answer to your question is....
2/3 + 3/8
= (2 × 8) + (3 × 3)
3 × 8
= 25/24 OR 1 1/24
Hope this helps!!!! Sorry I took so long :)
Answer:
The probability that the average length of rods in a randomly selected bundle of steel rods is greater than 259 cm is 0.65173.
Step-by-step explanation:
We are given that a company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 259.2 cm and a standard deviation of 2.1 cm. For shipment, 17 steel rods are bundled together.
Let = <u><em>the average length of rods in a randomly selected bundle of steel rods</em></u>
The z-score probability distribution for the sample mean is given by;
Z = ~ N(0,1)
where, = population mean length of rods = 259.2 cm
= standard deviaton = 2.1 cm
n = sample of steel rods = 17
Now, the probability that the average length of rods in a randomly selected bundle of steel rods is greater than 259 cm is given by = P( > 259 cm)
P( > 259 cm) = P( > ) = P(Z > -0.39) = P(Z < 0.39)
= <u>0.65173</u>
The above probability is calculated by looking at the value of x = 0.39 in the z table which has an area of 0.65173.
