7. If a set of data points has a trend line of y = 4.2x - 3, what is the predicted value of x when
1 answer:
Answer:
The predicted value of x = 2
Step-by-step explanation:
y = 4.2x - 3 is the given equation.
Now, y = 5.4
Putting in the above equation, we get
5.4 = 4.2x - 3
or, 5.4 + 3 = 4.2x
or, 8.4 = 4.2 x
⇒ x = 8.4/4.2
⇒ x = 2

Answer:1.2675x10^37
Step-by-step explanation:
3.9x10^33 x 3.25x10^3
3.9x3.25x10^33x10^3
12.675x10^(33+3)
12.675x10^36
1.2675x10^1x10^36
1.2675x10^(1+36)
1.2675x10^37
Answer:
x = 38
y = 41
z = 123
Step-by-step explanation:
x + y + z = =202
y = x + 3
z = 3y = 3(x + 3) = 3x + 9
<u>x</u> + <u>y</u> + <u>z</u> = <u>x</u> + <u>x + 3</u> + <u>3x + 9</u> = 5x + 12 = 202
5x + 12 = 202
5x = 190
x = 38
y = x + 3 = 41
z = 3y = 123
Step-by-step explanation:
since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is
So probabaility for is
So expected frequency for is (or .
