5 times 5 means there are 25 total choices

since there is a total of five questions and each question has one correct answer 5out of 25 are correct

so you have a 5/25 chance which simplifies to 1/5th probability

The probability of getting all 5 right would be 1/<span>3125

This is because each question has one choice. Making it a 1/5 chance for each question. 

Now if you combine if you add the rest you will have to calculate.

You would do the calculation by multiple the chance for a correct answer for each question together.

1/5 x 1/5 x 1/5 x 1/5 x 1/5 = 1/3125

I hope this helped!</span>

Simplify: (x+7)(x-4)
SVETLANKA909090 [29]

Answer:

x² + 3x - 28

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor

(x + 7)(x - 4)

= x(x - 4) + 7(x - 4) ← distribute both parenthesis

= x² - 4x + 7x - 28 ← collect like terms

= x² + 3x - 28

SVEN [57.7K]
1. X(0,0) --> X'(3,-5).
    To go from (0,0) to (3,-5), you must go to the right 3 and down 5.

I cannot answer 2 or 3, as rotations are not my strong suit.

What is the 308th term of the sequence 11,12.5,14,15.5,17...
Alecsey [184]

\huge\boxed{471.5}

The formula for an arithmetic sequence is as follows:

a_n=a_1+(n-1)d

In this formula, a_n represents the nth term of the sequence and d represents the common difference between each term.

Plug in the known values.

a_{308}=11+(308-1)1.5

Subtract.

a_{308}=11+307*1.5

Multiply.

a_{308}=11+460.5

Add.

a_{308}=\boxed{471.5}

John currently has $5000 in his savings
Alexus [3.1K]
John has $5,000 in his savings. That’s the total.
He has to give his sister $50 for her birthday.
He also spends $450 for his car payment.
We can easily put this into an equation.
50x-450=5000
Now we have to solve it.
50x-450=5000
-450 -450
50x=5000-450
50x=4550
50x/50=4550/50
x=91
So it will take 91 months to spend his $5,000.
