Answer: 9

Step-by-step explanation:

We know that he can walk one mile in 1/3 of an hour. We can divide 3 by 1/3.

3/(1/3) When dividing by a fraction, we multiply its reciprocal instead.

3*3=9. This means that he can walk 9 miles in 3 hours.

rooks are randomly placed on different squares of a chessboard. A rook is said to attack all of the squares in its row and its c

Olegator [25]

Answer: $2*8^{8}-8!$

Step-by-step explanation:

We can place a rook in each row in $8^{8}$ ways.

We can place a rook in each column in $8^{8}$ ways.

So the total ways in which we can place a rook in a row or column is $2*8^{8}$

Now there are 8 ways to choose the column for the first row, 7 ways to choose the column for the second row, and so on. So there are 8! ways to choose a column for a row.

So, we get the final answer by subtracting the 8! from the total ways a rook can be placed which is $2*8^{8}-8!$ when binomial coefficients are not evaluated

Answer:

Step-by-step explanation:

<h3>Mean, Median,mode</h3>

$\boxed{Mean = \dfrac{Sum \ of \ all \ data}{number \ of data}}$

$\sf = \dfrac{234 + 247 + 236+212+248+243+176+195}{8}\\\\= \dfrac{1791}{8}\\\\= 223.875$

<h3>Median:</h3>

Arrange the numbers in ascending order.

176 , 195 , 212 , 234 , 236 , 243 , 247, 248

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

$\sf = \dfrac{234+236}{2}\\\\ =\dfrac{470}{2}\\\\= 235$

Mode is the data which is occurring more number of times.

Range = maximum - minimum

= 248 - 176

= 72

loris [4]

Answer:

Check explanation

Step-by-step explanation:

Given:

y = -0.1x + 22

Where,

y = BMI of an individual

x = antioxidant food consumption per day in cups

Equation of a slope

y = mx + c

Where,

m = slope

c = y - intercept

Therefore,

From the equation

y = -0.1x + 22

slope, m = -0.1

y - intercept, c = 22
