Answer:

x=1

Step-by-step explanation:

2x-17x+15=0

Combine like terms

-15x +15 = 0

Add 15x to each side

-15x+15x+15=0+15x

15 = 15x

Divide by 15

15/15 = 15x/15

1 =x

Answer:

x=1

Step-by-step explanation:

x=1 because you need to isolate the variable by dividing each side factors that don't have a variable.

Answer:

Option 4 is correct that is according to fundamental theroem of algebra the given polynomial function will have 5 roots

Step-by-step explanation:

The fundamental theorem of algebra says that the polynomial will have  the number of roots  equal to the degree of the polynomial.

Degree is the highest power of polynomial.

Here we have given the polynomial where degree is 5.

Hence, the given polynomial will have 5 roots.

Therefore, option 4 is correct that is 5 roots

Answer:

U (1, 16 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ), then the midpoint M is

M = ( , ) ← midpoint formula

let (x₁, x₂ ) = U (x, y ) and (x₂, y₂ ) = V (13, 8 )

substitute these values into the midpoint formula and equate to the corresponding coordinates of M (7, 12 )

= 7 ( multiply both sides by 2 )

x + 13 = 2 × 7 = 14 ( subtract 13 from both sides )

x = 1

and

= 12 ( multiply both sides by 2 )

y + 8 = 2 × 12 = 24 ( subtract 8 from both sides )

y = 16

coordinates of U = (1, 16 )

Answer:

Step-by-step explanation:

Given that the random variable x represents the number of phone calls an author receives in a​ day

Poisson distribution is a discrete distribution with random variable countable.

Here no of calls cannot be in fraction or decimal.

Also given that X is Poisson with mean = 7.6

X is discrete since no of phone calls can take values as 1,2,3....

X can take any value from 0 to infinity.

x=3.2 is not possible since 3.2 calls does not exist.

Answer:

the possible values of​ x is 0,1,2,3...
