One third of herd of deer are grazing in the field as three fourths of the remaining are playing nearby .The rest 8 are drinking water from the pond .find the number of deer ​

Answer»

ong>Step-by-step explanation:

Given:

  • 1/3 herd of deer grazing in the field.
  • 3/4 of remaining are PLAYING nearby.
  • And rest 8 are drinking water.

To find:

  • the number of deer.

ANSWER:

Let the total number of deer in the herd be n.

Then, the number of deer grazing in the field be n/3.

Also, the 3/4 of the remaining ( i. e., n - n/3 = 2n/3 ) are

playing nearby.

So, their number is 3/4× 2n/3 = n/2

so, the rest number of deer = n - n/3 - n/2= n/6

According to QUESTION,

the rest number of deer is 8.

=> n / 6 = 8

=> n = 8×6

=> n= 48

Thus, the number of deer in the herd is 48 .

Arrange the following rational no's -5/3 , 7/-12 and 4/15 in descending order.

Answer»

ong>Answer:

Step-by-step explanation:

-13 by 20,6 by 15, 7 by 12, -9 by 10, 3 by 5

denominator terms are

20 , 15 , 12 ,10 & 5

We will find LCM of these NUMBERS first

20 = 5×2×2

15= 5×3

12 = 3×2×2

10=5×2

5 = 5

LCM = 5×3×2×2 = 60

lets multiply NUMERATOR and denominator to make denominator of each number = 60

ascending ORDER

-9/10 , -13/20 , 6/15 , 7/12 , 3/5

DESCENDING order will be

3/15 , 7/12 , 6/15 , - 13/20 , -9/10

The mean and variance of a bianomial distribution are 4and3 respectively. Fix the distribution and find (x >_1)

Answer»

ong>ANSWER:

For a biomial distribution, E (X) = np and Var (X)= npq ( where p is the probility of success and q is the probility of FAILURE where q=1-p ).

NOTE The Following

np= 3

npq=

Thus, we have that 3q = and this q= ½.

SINCE We know that q=1-p, then p=½. plugging the value

of p into np=3, we get that n=6. Now that we know the

value for n,p and q, we can plug these into the binomial

mass function so that we can find the binomial mass

function is p( X=x)=(n^x) p^x. q^n-x

and so with n=6 ,p=½,q=½ and X=5.

.We have the following.

P (X=5)=()(0.5)(0.5)¹

3

= ___

Therefore, the probability of time success is

0.09375.

The ratio of ages of Kunal and Deepesh is 3:5. After 10 years this ratio becomes 5:7. What is the present age of Deepesh ? (A) 20 years(B) 25 years(C) 50 years(D) 15 years​

Answer»

Solution :

Let KUNAL's age be 3x and DEEPESH's age be 5x

After 10 years :

• Kunal's age = 3X + 10 and

• Deepesh's age = 5x + 10

According to the question :

\longrightarrow \sf \:  \dfrac{3x  + 10}{5x + 10}  =  \dfrac{5}{7}

\longrightarrow \sf \:  7(3x + 10) = 5(5x + 10)

\longrightarrow \sf \:  21x + 70 = 25x + 50

\longrightarrow \sf \:  21x  - 25x = 50 - 70

\longrightarrow \sf \:   - 4x =  - 20

\longrightarrow \sf \:   x =  \dfrac{20}{4}

\longrightarrow \sf \:   x = 5 \: years

\therefore Present age of Deepesh = 5x = 5(5) = 25 years.

The inclination of the line y =V3x - 5 is​

Answer» ONG>Answer:

60°

Step-by-step explanation:

Given LINE is : y=3 x-5

This is in the form of y= mx+c ,

here m = 3

SLOPE (m) = TAN theta =3

=>tan theta = tan 60°

=>theta = 60°

The inclination of line y= 3x-5 is 60°

The slope of a line made by x-axis with angle 'theta' is 'm = Tan theta '.
