Answer:

x = 11

Step-by-step explanation:

Given:

14 = number of white cabbages
x = number of purple cabbages
P(W) = 0.56

⇒ total number of cabbages = 14 + x

$\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}$

$\sf \implies P(W)=\dfrac{number \ of \ white \ cabbages}{total \ number \ of \ cabbages}$

$\sf \implies 0.56=\dfrac{14}{14+x}$

$\sf \implies 0.56(14+x)=14$

$\sf \implies 7.84+0.56x=14$

$\sf \implies 0.56x=6.16$

$\sf \implies x=11$

Find the slope of the line that passes through the points (10, 9) and (2, 4).

solniwko [45]

Answer:

slope = 5/8

Step-by-step explanation:

use the slope formula to find the slope: $\frac{y_2 - y_1}{x_2-x_1}$

$\frac{9-4}{10-2} = \frac{5}{8}$

An investigator wants to assess whether the mean m = the weight of passengers flying on small planes exceeds the FAA guideline o

stira [4]

Answer:

$H_{0}: \mu= 185$ and $H_{a}: \mu > 185$

Step-by-step explanation:

The null hypothesis $H_{0}$ states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form $H_{0}: parameter = value$

In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form $H_{0}: \mu= 185$ .

The alternative hypothesis $H_{a}$ states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms

$H_{a}: parameter > value\\H_{a}: parameter < value\\H_{a}: parameter \neq value$

The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use $H_{a}: \mu > 185$ as his alternative hypothesis.
