Answer:

99

Step-by-step explanation:

8 + 7(4^2 - 3)

Solve what’s in the parentheses first, starting with 4^2:

8 + 7(16 - 3)

Continue solving what’s in the parentheses:

8 + 7(13)

Considering the order of operations, multiply 7(13) before adding 8:

8 + 91 = 99

Answer:

A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.

B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:

5y-29=3y+19

Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.

C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.

rusak2 [61]

Answer: $15417.8

Step-by-step explanation:

Last year, Randy earned $64,241.00 of taxable income.

The federal income tax rate was 24%.

Amount earned= $64241

Taxable income rate = 24%

Amount paid as taxable income will be equal to the taxable income rate multiplied by the amount earned. This will give:

24% of $64241

= 24/100 × 64241

= 0.24 × 64241

= $15417.8

The amount paid as federal tax is $15417.8

A simulation is a mathematical model used to represent a situation.

  • A simulation can be a program or a physical test to "simulate" a situation to predict the outcomes.

When we combine two or more simple events we have a compound event

  • "Compound" means to combine, like a compound word would be a combination of two words

A Tree Diagram is a diagram that shows all the possible outcomes of an event

  • In a tree diagram, each possible outcome "branches" off the main stem, making the final diagram look like a tree with many separating branches.

All the possible outcomes or results is called the sample space

  • The outcomes are each different samples, and a sample space is a space that collects each of these samples

When an event is not affected by a previous outcome we have an independent event

  • This event is "independent", not affected by other factors, making it an independent event

Let me know if you need any clarifications, thanks!
