Answer:

t = 60/n

Step-by-step explanation:

The original equation we know is y = k/n

Since 12 people can assemble the set in 5 hours, when y is 5, n will be 12.

We can now input that value into the equation.

--> 5 = k/12

--> 5(12) = k/12 (12)

--> 60 = k

--> k = 60

The equation to represent the situation can be written as:

t = 60/n

and that is our final answer!

Answer:

y = 6x + 0

Step-by-step explanation:

Lets find the rate of change, or slope:

ROC = $\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

ROC = $\frac{36-30}{6-5}$

ROC = $\frac{6}{1}$

ROC = 6

So, now we can input 6 in y = 6x + b

Now lets pick an x and y value (Im picking 5 and 30, but you can another one)

30 = 6(5) + b

30 = 30 + b

b = 0

The equation is y = 6x + 0

Paraphin [41]

Answer:

0.3557 = 35.57% probability that one selected subcomponent is longer than 118 cm.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 116 cm and a standard deviation of 5.4 cm.

This means that $\mu = 116, \sigma = 5.4$
