Answer:
It's asking you to find the inputs of the function.
Step-by-step explanation:
Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.
As the number of hours spent working increases, the amount of time spent on video games decreases.
Going from left to right, we see that the points are moving down. This means that the hours working are going up and the video game hours are going down.
4/10 and 6/15. I got these answers by multiplying the numerator and denominator by 2 to get 4/10 and then multiplied the numerator and denominator by 3 to get 6/15. If you were to simplify these fractions completely, you would be left with the original fraction, 2/5.
Answer:
25.88
Step-by-step explanation:
Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
