Given:

2 ft³ of clay was mixed into 7 ft³ of soil containing 55% clay.

To find:

Clay content of the mixture.

Solution:

We have,

55% of soil is clay. So,

Clay in soil= 55% of soil

\text{Clay in soil}=\dfrac{55}{100}\times 7

\text{Clay in soil}=\dfrac{385}{100}


\text{Clay in soil}=3.85


2 ft³ of clay was mixed into the soil. So, the total clay content of the mixture is

2+3.85=5.85\text{ ft}^3

Therefore, the clay continent in the mixture is 5.85 ft³.

MariettaO [177]

Answer:

The probability that randomly selected road will be at least 25.8 cm long will be 48%.

Step-by-step explanation:

Given: uniform distribution with min and max values of 18 and 33 respectively.

To find : probability density for upper cumulative frequency i.e 25.8 at least means x\geq25.8  upto 33 cm i.e the maximum limit of function.

Solution:

we have by definition , of uniform distribution

we get , probability density function defines as :

<em>F(x,a,b)= </em>\frac{1}{b-a}<em>   </em>a\leq x\leq b

            =1/(33-18)=1/15=0.0667.

this is probability density function.

here the x=25.8 , a=18 and b=33

for lower cumulative frequency it defines as ;

P(x,a,b)=\frac{x-a}{b-a} =25.8-18/33-18=0.52

for upper cumulative frequency it defines as ;

Q(x,a,b)=b-x/b-a=33-25.8/33-18=0.48

here at least 25.8 cm probability means it should be greater than a value(18cm) hence it is provided by the upper cumulative frequency

i.e. Q(x,a,b)=0.48

The probability that randomly selected road will be at least 25.8 cm long will be 48%.
