John is playing a game of darts. The probability that he throws a dart into the center of the dart board (the Bull’s eye) is. Th
Digiron [165]

The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

<h3>What is probability?</h3>

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

John is playing a game of darts. In this game of dart,

  • The probability that he throws a dart into the center of the dart board (the Bull’s eye) is 1/10.
  • The probability that he throws the dart into the 10-point ring is 3/10.

The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.

Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,

P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}

Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

A rectangular block measures 3 cm x 4 cm x 3 cm how much water would it displace?
nika2105 [10]

Answer:

36c^3m^3x^2

Step-by-step explanation:

  1. you first multiply 3 cm by 4 cm by 3 cm to get 36 cm.
  2. its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).
  3. 1.0 g/cm3
  4. then you get the answer 36c^3m^3x^2

Find the vertex, zero(s), and y-intercept of the graph of y = –x2 + 4x + 32.
xxMikexx [17]

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

y=-x^2+4x+32

Put x=0, in the given equation.

y=-(0)^2+4(0)+32=32

The y-intercept is (0,32).

Put y=0, to find the x-intercept.

0=-x^2+4x+32

0=-x^2+8x-4x+32

0=-x(x-8)-4(x-8)

0=-(x+4)(x-8)

x=-4,8

Therefore the y-intercepts are (-4,0) and (8,0).

The vertex of a parabola f(x)=ax^2+bx+c is

(-\frac{b}{2a},f(-\frac{b}{2a}))

-\frac{b}{2a}=-\frac{4}{2(-1)}=2

Put x=2 in the given function.

y=-(2)^2+4(2)+32

y=-4+8+32

y=36

The vertex is (2,36).

Therefore option A is correct.
