Answer:

1/3

Step-by-step explanation:

Probability of solving ten problems by Carl

Given

Total number of problems = 20

Number of problems studied by Carl = 15

Number of problems out of the 20 set of problem coming in test is 10

Case I - All ten problems come from the set of known 15 question

10/15 * 10/20 = 1/3

A polynomial is factored using algebra tiles. An algebra tile configuration. 0 tiles are in the Factor 1 spot and 0 tiles are in
MatroZZZ [7]

Polynomials consist of both indeterminates and coefficients. The polynomial that was factored in is x² - 2x - 8.

<h3>What are polynomials?</h3>

A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.

Given to us

1 is labeled x squared,

2 are labeled x,

4 tiles below x squared are labeled negative x,

8 tiles below the x tiles are labeled negative.

As we know that algebra tiles are the tiles that represent variables or coefficients. Also, the shape of the tiles can be rectangle or square.

These tiles can be represented as,

1 is labeled x squared, = x²

2 are labeled x,  = 2x

4 tiles below x squared are labeled negative x = -4x

8 tiles below the x tiles are labeled negative = -8

Sum all the terms we will get,

x² + 2x - 4x - 8

x² - 2x - 8

Hence, the polynomial that was factored in is x² - 2x - 8.

Please help. Find the product or quotient in simplified form. Explain how to multiply and divide fractions.
miskamm [114]
<span>5 1/6 x 1/3
</span>first convert 5 1/6 (which is a mixed fraction) into an improper fraction ...
=> 6*5+1/6 = 31/6
=>now we have ... 31/6 * 1/3
=> to multiply fractions we multiply the numerators ( top numbers ) with each other and the denominators (bottom numbers ) also the same way ...
=> 31/6 * 1/3 => 31*1 / 6*3 => 31/18 
=> then divide them to get answer as mixed fraction ..
=> 1 13/18  ..

<span>3 1/2 / 1 1/3
</span>=> here also first convert 3 1/2 and 1 1/3 into improper fractions ..
=> 3 1/2 => 2*3+1/2 => 7/2 
=> 1 1/3 => 3*1+1/3=> 4/3
=> now divide them ..
=> 7/2/4/3 
=> for dividing fractions we take the reciprocal of one fraction and then multiply ..
=> 7/2 * 3/4 
=> now multiply these two fractions ..
=> 7*3/2*4 => 21/8 
=> answer as mixed fraction = 2 5/8 ...

Hope it helps !!!

What is the measure of NRS?
never [62]

Answer:

<h3>C. 113°</h3>

Step-by-step explanation:

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

(7x - 1) +79  = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x +  78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\  \frac{70}{14}  = x \\ 5 = x \\

NRS = 21x + 8

21x + 8 \\ 21(5) + 8 \\ 105 + 8 \\  {113}^{o}
