If ray AB is the angle bisector of Im in geometry freshman year and I have absolutely no idea how to solve this I’m taking notes

Anvisha [2.4K]

Answer:

x=8

Step-by-step explanation:

Angle bisector means it cute the big angle into two equal, smaller angles (like cutting a piece of cake in half)

therefore, you can set both smaller angles equal to each other, then solve for x

4x+1=33 Subtract 1 from both sides

4x=32 Divide both sides by 4

x=8

You'll get it, keep studying! :)

Answer:

2400

8400

Step-by-step explanation:

You need to know the Divisibility Rules for 3, 5, and 8.

For 3: If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.

For 5: If the last number is either 0 or 5, the entire number is divisible by 5.

For 8: If the last three digits of a whole number are divisible by 8, then the entire number is divisible by 8.

You can put 0 to the end to meet the requirements of the divisibility rule of 5,

so it should be like _ _ _ 0

for 8, you can use 400 so it should look like _ 400

For 3, the sum of the digits needs to be divisible by 3

if we say X to the first digit the sum of the digits is x+4

we can use 6 and 9, so x can be 2, 5, and 8.

Therefore we have:

Answer:

Step-by-step explanation:

5.1 × 108 = 550.8

9.6 × 10^0

10^0 = 1

9.6 × 1 = 9.4

2.44 × 10 = 24.4

Twenty-nine percent of americans say they are confident that passenger trips to the moon will occur in their lifetime. You rando

galina1969 [7]

Answer:

The probability is 0.0014

Step-by-step explanation:

When we have two possible outcomes p, q and we repeat the experiment multiple times, we apply the Binomial distribution, in this distribution the probability of getting exactly k successes in n trials is given by

$P(X=k) = nCk(p)^k(1-p)^{n-k}$

where p represents the probability of success. nCk refers to the combinations of k elements out of n elements.

In this case, p= .29 (the probability that the person says "yes" being confident that passenger trips to the moon will occur in their lifetime.

q = .71 (The probability that the person says "no")

We sample 200 americans, therefore, we have n = 200 and we need the probability that less than 40% of the people sampled answer "yes".

The 40% of 200 is 80. So, in other words, we need less than 80 people to answer yes to the question.

P(x<80) = P(x=0) + P(x=1) + P(x=2) + .... + P(x=79) = 0.00143466294 (we can use a Binomial Distribution calculator to compute this result)

Therefore, P(x < 80) = 0.0014
