one third of a land is on maize, a fifth of the remainder is on potatoes and the rest which is 0.5 ha is on beans. how much of t
disa [49]

Answer: 1250\ m^2

Step-by-step explanation:

Let x= Total land.

Then for Maize = \dfrac{x}{3}    

For Potatoes = \dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x

For beans = x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha

\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\  \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\  \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\  x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\  x=0.9375 \ ha

1 ha = 10000.00 m²

0.9375 ha = 9375 m²

Land for potatoes = \dfrac{2}{15}(9375) =1250\ m^2

Hence, 1250\ m^2 of the land is on potatoes.

kolbaska11 [484]
Area of the square  = 11*11 = 121 
Area of the circle  = pi r^2 = pi*1^2 =  3.142
Part A
P( hitting the circle = 3.142 / 121  =  0.026 which is closer to 0.
Part B.
P(  hitting the white portion)  = 1 - 0.026 = 0.974 which is closer to 1.

The average test scores for a particular test in algebra was 84 with a standard deviation of 5. What percentage of the students
bija089 [108]

Answer:

The percentage of the students scored higher than 89% is 15.87%

Step-by-step explanation:

we are given

The average test scores for a particular test in algebra was 84

so, mean is 84

\mu=84

a standard deviation of 5

so,

\sigma=5

we have

x=89

now, we can use z-score formula

z=\frac{x-\mu}{\sigma}

now, we can plug values

z=\frac{89-84}{5}

z=1

now, we can use calculator

and we get

p(z>1)=0.1587

So,

The percentage of the students scored higher than 89% is 15.87%
