Answer:

Mean:9

MAD:2.7

Step-by-step explanation:

Mean:7+6+17+8+7+9=54/6=9

MAD: 9-6.3=2.7

(6.3 is the mean absolute deviation)

Answer: Mean: 9

MAD: 46

Step-by-step explanation:

I will show u how to work out the mean

and the mad so u know

MEAN:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

MAD:

1) To find the mean absolute deviation of the data, start by finding the mean of the data set.

2 )Find the sum of the data values, and divide the sum by the number of data values.

3) Find the absolute value of the difference between each data value and the mean: |data value – mean.

What are the exact solutions of x2 − 5x − 1 = 0 using x equals negative b plus or minus the square root of the quantity b square

geniusboy [140]

Answer:

$x=2.5+\frac{\sqrt{29}}{2}\\\\x=2.5-\frac{\sqrt{29}}{2}$

Step-by-step explanation:

So the question here is asking you to use the quadratic formula which is expressed as: $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\$

A quadratic can generally be expressed as: $y=ax^2+bx+c$

So using the equation you gave: $0=x^2-5x-1$

We can identify the following values: a=1, b=-5, c=-1

Btw the equation explicitly write "1" as the coefficient of x, but since it's not provided it's implied that it's 1.

So plugging in the known values, we get the following equation:

$x=\frac{5\pm\sqrt{(-5)^2-4(1)(-1)}}{2(1)}\\\\x=\frac{5\pm\sqrt{25+4}}{2}\\\\x=\frac{5\pm\sqrt{29}}{2}\\\\x=2.5+\frac{\sqrt{29}}{2}\\\\x=2.5-\frac{\sqrt{29}}{2}$

The last step just consists of taking the + and - solution, and since it asks for exact solutions you leave the 29 under the radical, and you don't approximate. There is no further simplification that can be done here.

If 55% people in a city like Cricket, 30% like Football and the remaining like nother games, then what per cent of the people li

labwork [276]

$\large{\dag\:{\underline{\underline{\frak{\pmb{\red{Answer:-}}}}}}}$

Cricket = 55%
Football = 30%
Other games = Remaining (?)

So, the percent of people who like other games equals:

= 100 – (55 + 30)

= 100 – 85

= 15%

If the total no. of. people is 60,00,000:

★ Cricket

= 60,00,000 × 55/100

= 33,00,000

★ Football

= 60,00,000 × 30/100

= 18,00,000

★ Other sports

= 60,00,000 × 15/100

= 9,00,000
