Answer:

x = 45

Step-by-step explanation:

x and 3x are adjacent angles and the form a straight line. Their sum will be 180 degrees

x +3x = 180

Combine like terms

4x = 180

Divide each side by 4

4x/4 = 180/4

x =45

Answer:

45°

Step-by-step explanation:

The angle of a supplementary line is 180 degrees, this means that:

x+3x=180 Solve for x

4x=180

x=45, The value of x is 45°

What is r in this equation?<br> 3 3/4 + r = 5 3/8

gayaneshka [121]

Answer:

r is 1 5/8

Step-by-step explanation:

3 3/4 is the same as 3 6/8, now both denominators are the same.

5 3/8 - 3 6/8 is the same as 43/8-30/8 which is 13/8, or in mixed number form, 1 5/8.

So r=1 5/8

Select the correct answer.

Answer:

R(2, 4)

Step-by-step explanation:

The general equation for a circle centered at (h,k) with radius, R, is

(x-h)^2 + (y-k)^2 = R^2

Putting the values in formula,

(x-6)^2 + (y-1)^2 = 5^2

Putting the coordinates (2, 4) of the answer B(2-6)^2 + (4-1)^2 = 25

(-4)^2 + 3^2 = 25

16 + 9 = 25

25 = 25

R.H.S = L.H.S

So according to the above solution,

B) R(2, 4), is the correct answer.

Find the probability distribution of x

Answer:

The random variable x is defined as: X = {0, 1, 2, 3, 4}

The probability distribution of X:

P(X = 0) = 0.656

P(X = 1) = 0.2916

P(X= 2) = 0.0486

P(X=3) = 0.0036

P(X = 4) = 0.0001

Step-by-step explanation:

Sample size, n = 4

Random variable, X = {0, 1, 2, 3, 4}

10% (0.1) of the homeowners are insured against earthquake, p = 0.1

Proportion of homeowners who are not insured against earthquake, q = 1 - 0.1

q = 0.9

Probability distribution of x,

$P(X = r) = ^nC_r *p^r q^{n-r} \\\\P(X= 0) =(^4C_0 *p^1 q^4 )\\P(X=0) = (^4C_0 *0.1^0 0.9^4 ) = 0.656\\P(X= 1)= (^4C_1 *p^1 q^3 )\\P(X=1) = (^4C_1 *0.1^1 0.9^3 ) = 0.2916\\P(X= 2)=( ^4C_2 *p^2 q^2) \\P(X=2) = (^4C_2 *0.1^2 0.9^2 ) = 0.0486\\P(X= 3) = (^4C_3 *p^3 q^3) \\ P(X=3) = (^4C_3 *0.1^3 0.9^1 ) = 0.0036\\P(X= 4) = (^4C_4 *p^4 q^0 )\\ P(X=4) =(^4C_4 *0.1^4 0.9^0 ) = 0.0001$
