IF YOU DONT KNOW THE ANSWER DONT ANSWER!! ANSWER ALL QUESTIONS

Answers

Answer:

A, A, A, B, D

Step-by-step explanation:

1.

P(A) = 1/6, P(B) = 1/2

P(A and B) = 1/6*1/2 = 1/12

2.

P(A) = 1/6

P(B) = 1/6

P(A and B) = 1/6*1/6 = 1/36

3.

P(A) = 2/6 = 1/3

P(B) = 1/3

P(A and B) = 1/3*1/3 = 1/9

4.

P(gold) = 4/7 for each

P(2 golds) = 4/7*4/7 = 16/49

5.

Remaining marbles:

2 white, 1 orange and 2 green. Total 5 marbles

P(green) = 2/5

Henry's dog ate 8 cans of dog food this week. Each can contain 55.4 grams of protein. How much protein was this in all?

Answers

Answer:

443.2 grams

Step-by-step explanation:

Each can contains 55.4 grams of protein, and there are 8 cans, so the answer would be 55.4*8 = 443.2 grams.

The answer is 443.2 grams of protein.

Since there are each can had 55.4g of protein, and Henry’s dog ate 8 of them, you can think of it as 55.4 • 8 = 443.2

may someone please help me understand something in class? its theoretical and experimental probability basically just probability in a whole and I can’t understand. I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.

Answers

Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

hope this helped.

Evaluate the expression : 5/9 ( F - 32) when F = 122

2. 60
3. 40
4. 20

Answers

1.50 5/9(122-32)=5/9(90)= 50

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11


Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180

Answers

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.
