1. When there are two events that need to happen, we must multiply the probability of each event happening.

Shawn losing to Mike: 5/8 chance
Shawn losing to Tim: 2/7 chance

5/8 × 2/7 = 10/56 = 5/28

There's a 5/28 chance of Shawn losing to Mike and Tim.

I don't know #2, sorry :/

Hope this helps!

A researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment. If all the treatments had the same numbe

Vsevolod [243]

Answer:

13 participants.

Step-by-step explanation:

Given that a researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment.

i.e. degrees of treatment between groups =1

and within groups = 24

This implies that there are two groups.

For two groups to have same number of participants, since we get total of degrees of freedom =24+1 =25

Hence total items selected = 26

i.e. each group would have 13 entries

So each treatment had 13 participants.

Which represents the reflection of f(x)=sqrt x over the y axis

zloy xaker [14]

reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be $g(x)= f(-x)$

So, finding reflection of $f(x)=\sqrt{x}$ over the y axis we get:

$g(x)=\sqrt{-x}$

So, reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

An average of 145 people visited a 4-day exhibition on the first 3 days. Another 205 people visited the exhibition on the fourth

Alenkinab [10]

Answer:

160 visitors.

Step-by-step explanation:

Given:

An average of 145 people visited a 4-day exhibition on the first 3 days, <u>means here average people visited in 3 days is given 145.</u>

Average = 145

Number of people, n = 3

Another 205 people visited the exhibition on the fourth day.

To find:

What is the average number of visitors per day ?

Solution:

<u>First of all we will find total number of people visited in 3 days:-</u>

As we know:

$Average=\frac{Sum\ of\ observation}{number\ of\ observation}$

$145=\frac{Sum\ of\ observation}{3}\\$

Multiplying both sides by 3

$145\times3=\frac{Sum\ of\ observation}{3}\times3\\435=Sum\ of\ observations$

Thus, we found that total number of people visited in 3 days is 435 and as 205 people visited in fourth day, then total number of people increased to

435 + 205 = 640

Now, sum of total observations( total number of people ) = 640

And number of observation ( number of days ) = 4

Now, we will calculate average number of visitors visit per day :-

$Average=\frac{Sum\ of\ observation}{number\ of\ observation}$

$=\frac{640}{4} \\=160\ visitors$

Thus, the average number of visitors per day is 160 visitors.
