Answer:

Answer:

Isosceles

Step-by-step explanation:

If BD is an altitude, it splits triangle ABC into 2 triangles.  It is also a median, so it splits the angle ABC into 2 congruent angles.  Angle ABD and CBD are congruent.  That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles.  Because of this, side AB and side CB are congruent.  That means that this is an isosceles triangle.

A system in a noisy environment transmits 11111 or 00000 when 1 or 0 are transmitted to decrease the probability of error. Suppose the probability that one of the 5 transmitted bits is corrupted from 1 to 0 is 0.3 and the probability that a bit is corrupted from 0 to 1 is 0.1. Given that the probability that the system transmits a 0 or a 1 is equally likely, if 01101 was received what is the probability that a 1 was transmitted.

Answers

Answer: The probability that a 1 was transmitted is (0.3)²(0.7)³ which = 0.031

PZ HURRY. find angle b.​

Answers

Answer:

b = 60°

Step-by-step explanation:

If you look at the side under the 30° angle, there's a small red box, signifying a right (90°) angle. Doing the math, then, you would do:

90 = 30 + b

b = 60

60° if im not mistaken. the right angle is 90° and 30°+b is also 90° as 180°-90°=90°. therefore 90°-30°=60°. hope it helped!

There are 90 yellow flowers, 54 red flowers, and 36 white flowers for centerpieces. If the flowers need to be divided equally into separate centerpieces with the same number of each color of flower in each centerpiece, how many different centerpieces will there be?

Answers

Answer:

You can create the fewest centerpieces for the smallest number of any color, which is 2 centerpieces using the white flowers. Therefore, you will have 2 centerpieces with an equal number of each color of flower in each centerpiece.

Step-by-step explanation:

First, find the GCD of 90, 54, and 36:

Find the GCD of 90 and 54:

GCD(90, 54) = 18

Find the GCD of the result (18) and 36:

GCD(18, 36) = 18

So, the GCD of 90, 54, and 36 is 18.

Now, you can create centerpieces with 18 flowers of each color (yellow, red, and white) in each centerpiece. To find out how many centerpieces you can create, divide the total number of each color by 18:

Number of yellow flowers / 18 = 90 / 18 = 5 centerpieces

Number of red flowers / 18 = 54 / 18 = 3 centerpieces

Number of white flowers / 18 = 36 / 18 = 2 centerpieces

You can create the fewest centerpieces for the smallest number of any color, which is 2 centerpieces using the white flowers. Therefore, you will have 2 centerpieces with an equal number of each color of flower in each centerpiece.

What is the domain of the function below?
{0,2 3,1 5,2 8,4

Answers

The choices are the below that can be found elsewhere:

a. { 1, 2, 4 }
b. { 0, 3, 5, 8 }
c. { 0, 1, 2, 3, 4, 5, 8 }
d. { ( 0, 2 ), ( 3, 1 ), ( 5, 2 ), ( 8, 4 ) }

The answer is B because the domain is just the X-values of the ordered pairs and you cant repeat them.
