One way to test if a graph is a function or not is by doing a?
KATRIN_1 [288]

One way to test if a graph is a function or not is by doing a <u>vertical line test</u>.

<em>The </em><u><em>vertical line test</em></u><em> is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.</em>

Hope that helps!

Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a the past year. Suppose a sa
strojnjashka [21]

Answer:

0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million

Step-by-step explanation:

We are given the following information in the question:

Mean, μ =$3.26 million

Standard Deviation, σ = $1.2 million 100

We assume that the distribution of salaries is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{1.2}{\sqrt{100}} = 0.12

P(mean salary of the 100 players was less than $3.0 million)

P(x < 3) = P(z < \displaystyle\frac{3-3.26}{0.12}) = P(z < -2.167)

Calculating the value from the standard normal table we have,

P(Z < -2.167) = 0.015 \\P( x < 3) = 1.5\%

0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million

Please I need help
GenaCL600 [577]

Answer:

Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with  1-\frac{1}8} of the original cake.

Step-by-step explanation:

Salary:     1

Spent \frac{2}{5} :     1-\frac{2}{5}

Spent \frac{1}{4}:      1-\frac{2}{5} -\frac{1}{4}

Spent \frac{1}{8}:      1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}

REMAINING: 1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}

Operate using LCM:  \frac{40-16-10-5}{40} =  \frac{9}{40}

The answer is (d)

erik [133]

Answer:

the price that Michael charge per pack is $16.01

Step-by-step explanation:

The computation of the price that Michael charge per pack is as follows:

= 124 sports card ÷ 4 cards

= 31 packs

Now the charge per pack would be

= $496.31 ÷ 31 packs

= $16.01

hence, the price that Michael charge per pack is $16.01

The same is to be considered
