Rolling a sum of seven with a pair of dice...any of the six numbers can be first so that probability is:

(6/6) or 1 :P

Now to roll a sum of seven only one unique number can follow the first so the probability of getting that unique number so that you have a sum of seven is:

(1/6)

This is a compound event because two thing must happen and you multiply their respective probabilities to get the probability of the compound even..

(6/6)(1/6)=6/36=1/6

7) Find the area of the shaded region:

aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

The area of the biggest rectangle =

$(9x - 2)(2x + 7) = 18 {x}^{2} + 63x - 4x - 14 = 18 {x}^{2} + 59x - 14$

The area of the of the smallest rectangle inside=

$3x(x + 12) = 3 {x }^{2} + 36x$

Then the area of the shaded region =

$18 {x}^{2} + 59x - 14 - (3 {x}^{2} + 36x) = 18 {x}^{2} + 59x - 14 - 3 {x}^{2} - 36x = 15 {x}^{2} + 23x - 14$

So, we choose B.

How do you convert the general equation form of a circle to standard form? Answer correctly to get 20 points. Please provide an

ivanzaharov [21]

Answer:

Step-by-step explanation:

The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.

Please answer ASAP. The question is down below

Nadusha1986 [10]

Answer: 1) D 2) B

Step-by-step explanation:

1) The denominator cannot equal zero, Factor the denominator to find the zeros. n³ - 4n² + 3n = 0

n(n - 3)(n - 1) = 0

n=0 n-3=0 n-1=0

n=0 n=3 n=1

2) In order to be a rational expression, it must be in the form $\dfrac{a}{b}$ where both a and b are integers.

Since $\sqrtb$ $\sqrt b$ is irrational and not an integer, then the expressions containing an irrational term after simplified cannot result in an integer.

Therefore, options (i) and (iv) are not rational expressions.

Option (iii) contains b as an exponent. Since there is no information about b, it could be a fraction, which means it could be an irrational number.
