Answer:

Probabilty= 7.66*10^-3

Step-by-step explanation:

A box contains 65 balls numbered from 1 to 65.

9 balls are drawn with replacement.

Probabilty of selecting a number = 1/65

Probabilty of selecting a number

= 0.0154

Probabilty of at least 2 numbers out of 9 selected to have Same number

Probabilty= 9C2(0.0154)^2(0.9846)^7

Probabilty= 7.66*10^-3

gavmur [86]

Answer:

x= -\frac{1}{32}

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+\frac{1}{2}=\frac{3}{8} Next move 1/2 to the right side. Now your equation is 4x=\frac{-1}{8}. Next divide both sides by 4 to isolate "x." Now your equation is x= -\frac{1}{32}

Hope this helped and have a great day.

The image of rectangle JKLM after a reflection over the y-axis around the origin is J = (6, -2), K = (6, -1), L = (0, -1) and M = (0, -2)

<h3>How to graph the image of rectangle JKLM after a reflection over the y-axis around the origin?</h3>

From the graph, the coordinates of the rectangle are:

J = (-6, -2)

K = (-6, -1)

L = (0, -1)

M = (0, -2)

The rule of a reflection over the y-axis around the origin is

(x, y) = (-x, y)

When the above rule is applied, we have the image to be:

J = (6, -2)

K = (6, -1)

L = (0, -1)

M = (0, -2)

Hence, the image of rectangle JKLM after a reflection over the y-axis around the origin is J = (6, -2), K = (6, -1), L = (0, -1) and M = (0, -2)

Answer:

theta = 24.4 degrees

Step-by-step explanation:

This is a right triangle.

sin theta = opp/ hyp

sin theta = 33/80

Take the inverse of each side

sin^-1 sin(theta) = sin^-1 (33/80)

theta =24.36197794

To the nearest tenth

theta = 24.4 degrees
