Hello!

A term is a number that is added. As you can see, all of the numbers in the numerator are added. This means that they are all terms, and as there are three, there are three terms.

A coefficient is a constant that is written as a multiplier of a variable. For example, in 3x, 3 is the coefficient. As you can see, in the denominator, 4 is just a constant term; it is not multiplied. Therefore, this statement is incorrect.

Next, in the denominator, 2 is multiplied by x², so it is a multiplier and coefficient.

As we said before, the numerator has three terms, not two, so this sentence is incorrect.

In the numerator, three is added, and is not a multiplier of a variable, so it is incorrect.

Therefore, our correct statements are the first and third sentences are correct, just as you put!

I hope this helps!

Elan Coil [88]

Answer:

(1.5, 2.5)

Step-by-step explanation:

(x,y) is being multiplied by 2 to get (3,5). We need to divide it by 2 to find x and y.

3/2= 1.5

5/2=2.5

Thus, the answer is (1.5, 2.5). Hope this helped!

E.

Step-by-step explanation:

A

-1/9×6=

-1/9×6/1= -6/9 = -2/3

B

-15 ÷ 10

-15/1 ÷ 10/1

-15/1 × 1/10 = -15/10 = -3/2

C

12 ÷ -18 =

12/1 ÷ -18/1 =

12/1 × -1/18 = -12/18 = -2/3

D

-3/4 ÷ 1/2 =

-3/4 × 2/1 = -6/4 = -3/2

3241004551 [841]

Answer:

d) 6.750

<em>The chi - square value = 6.750</em>

Step-by-step explanation:

Given data

Starting Position              1           2            3           4            5              6  

Number of Wins (O)       33        44            32         36         45           50

<u><em>Step(i) :</em></u>-

mean = \frac{33+44+32+36+45+50}{6} = \frac{240}{6} =40

Expected frequency = 40

Number of Wins (O)      :     33        44            32         36         45           50

Expected frequency(E)   :   40         40           40         40          40          40

(O - E )                              :    -7          4              -8           -4           5            10

(O-E)²                               :     49         16           64          16          25          100

\frac{(O-E)^2}{E}                              :      1.225    0.4       1.6         0.4         0.625     2.5  

<u><em>Step(ii):-</em></u>

<u><em>The χ² test</em></u>

<em>      χ²   =    ∑   </em>\frac{(O-E)^2}{E}<em></em>

<em>   χ²  =  1.225 + 0.4 + 1.6 + 0.4 +0.625 +2.5 = 6.75</em>

<em>The chi - square value = 6.750</em>

<u><em>Final answer</em></u><em>:-</em>

<em>The chi - square value = 6.750</em>

<u><em>                  </em></u>

<u><em></em></u>
