What is the sum or difference?
2x^4 +8x^4

Answer:

THe answere is 40

Step-by-step explanation:

If 24 brownies are sold, the number of ice cream cones sold is 40.

A linear equation is in the form:

y = mx + b;

where y, x is variable, m is the rate of change and b is the y intercept.

Let y represent the number of ice cream cones and x represent the number of brownies sold.

Since there were 5 ice cream cones for every 3 brownies sold at the ice cream shop. Hence:

y = (5/3)x

If 24 brownies are sold:

y = (5/3)x

y = (5/3) * 24 = 40

If 24 brownies are sold, the number of ice cream cones sold is 40.

Answer:

9 inches wide

Step-by-step explanation:

so in the text it tells you that the rectangle is 3 inches wide by 4 inches long

then it gives you the final length but you need the width. so what i did is find out how much the increase of the length was, the length was4 at the start then ended at 12 to find out how much it increased i divided 12 by 4 and got 3. that shows that the object is 3 times larger so then I multiplied the original width by 3 which would be 3*3 which equals 9. so 9 is the width of the enlarged shape.

Answer: 4/5 or 0.8

Step-by-step explanation: To find how much it grows over time, we have to find the slope. to do that, we need to have two points with exact points on the graph, so (0,0) and (4,5). the equation for slope is rise/run. it rises 4, and runs 5. so 4/5.

Answer:

Neither of the students are correct.

Step-by-step explanation:

Sarah:

P = 3x + x +7 + 3x + x +7 ..... this first step is correct

    = 6x + 14 .... this step is incorrect, Sarah forgot to add the other 2 xs

John:

P = 2(x + 7) + 2(3x)

  =  2x + 7 + 6x .... this step is incorrect, John forgot to distribute the 2 to the 7

  =  8x + 7 .... incorrect because of the previous step

The answer should've been 8x + 14.

Answer:

The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.

Step-by-step explanation:

According to the table, we have that the correct option is:

5.)The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.

Statement 1:

15 of 33 new are correctly classified, thus, the proportion is:

[tex]p_N = \frac{15}{33} = 0.4545[/tex]

18 out of 31 old, thus:

[tex]p_O = \frac{18}{31} = 0.58[/tex]

Proportions are different, thus, statement 1 is false.

Statement 2:

13 out of 31 old are incorrectly classified, thus:

[tex]p = \frac{13}{31} = 0.4194[/tex]

Different than 0.4545, thus, statement 2 is false.

Statement 3:

Out of 31 incorrectly classified, 13 are old.

Out of 33 correctly classified, 15 are new.

Different proportions, thus, statement 3 is false.

Statement 4:

Out of the 33 new, 15 are correctly classified and 18 incorrectly, different proportions, thus, statement 4 is false.

Statement 5:

18 out of 33 correctly classified are old.

18 out of 33 new violins are incorrectly classified.

Same proportion, thus, statement 5 is true.

C. The Texture of the Surface

Step-by-step explanation:

I know it's confusing because of A.. But if you think about what would happen if you were to bounce a ball with a lot of force onto the surface, it wouldn't cause a difference in the friction because it would still just bounce right back up. D. is also not applicable because the weight of the ramp wouldn't matter if the ball is rolling on top of it.

Answer:

a) 0.1818

Step-by-step explanation:

Given that:

The odd that it'll snow tomorrow is 9 to 6

The probability that it will snow tomorrow  [tex]=\dfrac{9}{9+6}[/tex]

[tex]=\dfrac{9}{15}[/tex]

= 0.6

The probability that it'll not snow tomorrow [tex]= 1 - \dfrac{9}{15}[/tex]

[tex]= \dfrac{15-9}{15}[/tex]

[tex]=\dfrac{6}{15}[/tex]

= 0.4

Let assume that the odd that it'll snow tomorrow is 9 to 2

The probability that it will snow tomorrow  [tex]=\dfrac{9}{9+2}[/tex]

[tex]=\dfrac{9}{11}[/tex]

= 0.8181

The probability that it'll not snow tomorrow  [tex]= 1 - \dfrac{9}{11}[/tex]

[tex]= \dfrac{11-9}{11}[/tex]

[tex]=\dfrac{2}{11}[/tex]

= 0.1818

None of the  options is correct.

Probability that it will not snow tomorrow = 0.4

The odds of an event E is defined as formulated in equation (1)

[tex]\rm Odd\; of\; event\; E = P(E)/P(\bar E) = P(E)/(1-P(E)).......(1)[/tex]

Let P(E) represents the probability that it will snow tomorrow.

Let event E represents the event that " it will snow tomorrow "

So the odds of the event that it will snow tomorrow

[tex]\rm \dfrac{P(E)}{P(\bar E)} =\dfrac{9}{6} = \dfrac{P(E)}{1-P(E)}.......(2)[/tex]

On solving equation (2) we get

[tex]\rm P(E) = \dfrac{9}{15}[/tex]

So the probability that it will snow tomorrow is 9/15

Hence the probability that it will not snow tomorrow

[tex]\rm P(\bar E) = 1- \dfrac{9}{15} = \dfrac{6}{15} =\bold{0.4}[/tex]

Probability that it will not snow tomorrow = 0.4

24=3n-15 or,25+15=3n or,39=3n or,39/3=n or,n=13 therefore the value of n is 13. I think this answer is helpful for you

Answer: n = 13

Step-by-step explanation:

24=3(n-5) - First  distribute the 3 to the n and the 5. Which you would than get 3n and -15

24=3n-15 - Now add the 15 to both sides which would cause it to cancel out on the left side of the equal side.

39=3n - Now divide the 3 from 3n on both sides of the equal side.

n=13 - Once you do that you will get n = 13. That is your answer!
