<u><em>**I want to mention that please use asterisk (*) symbol for multiplication as multiplication symbol x and variable x look the exact same</em></u>

Your question is

3*4+2*3-5*2+4*2+6x-2x-3*4+7x-3*3

First calculate each term getting

=12+6-10+8+6x-2x-12+7x-9

Now combine like term which means adding all of the constant together and all of the term containing variable x together

=11x-5

Therefore 11x-5 is the answer to the expression.

If the probability of a student spending time reading is 0.10, the probability of spending time watching TV is 0.90 and the prob
joja [24]

Answer:

The probability is 0.97

Step-by-step explanation:

In this question, we are concerned with calculating the probability of a student spending time reading or watching TV.

To calculate this, we simply use a direct mathematical formula.

P( of spending time reading or watching tv) = P(of spending time reading) + P(spending time watching Tv) - P( of spending time watching Tv and reading)

From the question, we identify the probabilities as follows;

P(spending time reading) = 0.1

P(of spending time watching Tv) = 0.9

P(of spending time watching Tv and reading) = 0.03

Now, plugging these values, we have

P( of spending time reading or watching Tv) = 0.9 + 0.1 -0.03

= 1-0.03 = 0.97

stepladder [879]

Answer:

The answer is C

Step-by-step explanation:

Let X and Y be two proportional quantities and let K be constant.

Y=KX so Y/X=K

So for Equation number 1 we have 4y=3x and we will fill it in for 4/3=K

solving to get 1.33...

Now repeat this for the rest to complete the chart

1-  1.33...

2.  1.6

3-  1.33...

4-  0.625

Now we can see that 1 and 3 are the same, so that's how you get your answer, hope this helps!
