Answer:the area of their front yard and side yards is:

2*3*10 + 9*9 = 141 m^2

They do not need to reseed a proportion of the front yard covering 16 square meters where a flower bed is located:

Suppose point z is halfway between point w and x a standard numberline, and point x is halfway between points z and y. Where is

Delicious77 [7]

Answer:

The point w is located at -4/3

Step-by-step explanation:

Point z is halfway between point w and x

Point x is halfway between point z and y

Point z is located at 1/3 and point y is located at 11/3

Please refer to the number line attached

Then the x is located at the mid-point of z and y

$x = \frac{z+y}{2} \\\\x = \frac{\frac{1}{3}+ \frac{11}{3} }{2}$

$x = 2$

Since z is the mid-point of w and x

$z = \frac{w+ x }{2}\\\\\frac{1}{3} = \frac{w+ 2 }{2}\\\\\frac{2}{3} = w+ 2 \\\\w = \frac{2}{3} - 2\\\\w = -\frac{4}{3}$

Therefore, the point w is located at -4/3

A random walker is observed to take a total of N steps, n of which are to the right (and the rest n^' are to the left). Suppose

ioda

Answer:

p = 0.635

Step-by-step explanation:

A step to the right is n and on ten different days, it was recorded to be

14, 13, 11, 12, 11, 12, 16, 16, 14, 8.

n = average of all the steps,

The average is the sum of variables divided by the number of variables

Average = (14+13+11+12+11+12+16+16+14+8)/10

Average = 12.7 steps.

σₙ² = variance of n

Variance is an average of the squared deviations from the mean.

[Σ(x - xbar)²/N]

Σ(x - xbar)² = (14-12.7)² + (13- 12.7² + (11-12.7)² + (12-12.7)² + (11-12.7)² + (12-12.7)² + (16-12.7)² + (16-12.7)² + (14-12.7)² + (8-12.7)² = 54.1

Variance = σₙ² = (54.1/10) = 5.41

standard deviation = σₙ = √(variance) = √5.41 = 2.326.

The proportion, p can be computed in two ways.

Mean = Np or standard deviation = √[Np(1-p)]

where N = total number of steps = 20

Mean = 12.7 = 20p

p = (12.7/20) = 0.635

Or

Standard deviation = 2.326 = √[20p(1-p)]

5.41 = 20p - 20p²

20p² - 20p + 5.41 = 0

Solving the quadratic equation,

p = 0.5 + 0.143i or p = 0.5 - 0.143i

not a unique or feasible solution, hence, the probability of a step to the right remains p = 0.635

Hope this Helps!!!

The perimeter of the rectangle below is:

blondinia [14]

Answer:

18x + 28 is the perimeter

Step-by-step explanation:

As perimeter is the som of all side

So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4

= 6x+3x+6x+2x+x + 8+6+5+2+3+4

= 18x + 28
