Step-by-step explanation:

Given :

3(a+3b)-4

a=4\\b=5

To Find : value of the given expression.

Solution :

3(a+3b)-4

Putting value of a and b

⇒3(4+3*5)-4

Solving this we will use BODMAS rule : According to this rule we need to follow the sequence for solving mathematical expressions

B - Bracket

O- Of

D - Division

M- Multiplication

A - Addition

S- Subtraction

Following this sequence we will solve the given expression

⇒3(4+15)-4

⇒3(19)-4

⇒57-4

⇒53

Thus, The value of the expression   3(a+3b)-4  is 53

Answer:

\frac{19}{18,750,000}=0.0000010133333333

Step-by-step explanation:

We have been given that in a recent​ year, 304 of the approximately​ 300,000,000 people in the United States were struck by lightning.

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{304}{300,000,000}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{19}{18,750,000}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=0.0000010133333333

Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is \frac{19}{18,750,000}=0.0000010133333333.

Multiplying to Fractions 
ExtremeBDS [4]

Answer:

B. No. The product of two fractions is the product of the numerators divided by the product of the denominators.

Step-by-step explanation:

For A: A is clearly false because you can multiply any fraction and it doesnt matter what the denominator is.

For B: The first part is correct, which is that to multiply two fractions, they dont have to have like/common denominators, the explanation part is also correct. When we multiply we multiply the numerator to the numerator and the denominator to the denominator.

For C: C is false because the first part says yes and we know that you can multiply any 2 fractions regardless of denominators.

For D: For D the first part is correct however, the explanation section is false you dont multiply the numerator to the denominator.

For E: You don't have to find the equivalent fraction to multiply because you can do that afterward.

I hope this helps, have a blessed day! :D
