Salman flips a fair coin 350 times.
Part A
How many times would you expect Salman to flip heads?
Part B
Was your answer to part a based on theoretical probability or relative frequency?
​Explain.
Part C
​How many times will Salman flip heads?
A 176
B176
C 165
DbYou really cannot tell for sure

Answers

Answer 1

Answer:

Part A- About 1/2(half) of 350 would be reasonable since there is only two options for all 350 flips.

Part B- Theoretical probability, since an experiment has yet to be conducted it can't be experimental.

Part C- a or b would be a good answer, unless one should be different.

Tell which property is being illustrated: 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7

Commutative Property of Addition
or
Additive Identity Property of 0.



Tell which property is being illustrated: 16 + 0 =16

Additive Identity Property of 0
or
Commutative Property of Addition

Answers

Answer:

Hi! For the first question, the property being demonstrated is the Commutative Property of Addition. For the second problem, the answer would be the Additive Identity Property of 0.

Step-by-step explanation:

In the problem 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7, we can see the commutative property being used. The Commutative Property of Addition states that changing the order of the addends will not have an affect on the sum. As long as you still keep the same addends, the sum will always remain the same regardless of the order.

In the problem 16 + 0 = 16, we see the Additive property of 0 being demonstrated. This property basically states that adding a number to 0 will give you the same number. It is usually very easy to identify if you look for 0 being added to an addend.

the length is 12 ft 3 inches.

147/12 = 12.25 and 1/4 of a foot is 3 inches so your answer is 12 ft 3 in

Answer:

12 ft 3 in

Step-by-step explanation:

12 feet would be 144 so you have to add three inches to get 147

another way to solve it would be to divide 147 by 12 to get 12.25 which is equal to 12 ft 3 in

Answer:

The third and fourth one

Step-by-step explanation:

Hii,

When you divide by a negative, the sign flips. In the third and fourth one you're dividing by a negative so the inequality sign flips. For the rest, you're not.

Hope this helps :)

the correct answer is the third and fourth one because it makes the most sense and it’s a closest answer

13. A right triangle has sides 8 and 12.


a. Find the missing side if 8 and

12 are legs.


b. Find the missing side if 8 and

12 are a leg and hypotenuse.

Answers

A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94
So the pythagorean theorem is a^2 + b^2 = c^2. in this case it would be 12^2 + 8^2 = c^ 2

Explanation:
12^2 = 144
8^2= 64
64 + 144 = c^2
208 = c^2
in order to find c we need to square root both sides of the equation, you can plug that into the calculator.
c = about 14.4
