If the following data were linearized using logarithms, what would be the equation of the regression line? Round the slope and y
Elis [28]

Answer:

  • log y = 0.576x + 0.139

Step-by-step explanation:

<u>Given data:</u>

  • <u>x  |  2   |   3   |  4    |   5      |  6     </u>
  • y  | 21   |  69 | 261  | 1029  |  4101​

<u>Logarithms of y-values:</u>

  • log 21 = 1.322
  • log 69 = 1.839
  • log 261 = 2.417
  • log 1029 = 3.012
  • log 4101 = 3.613

<u>The ordered pairs:</u>

  • (2, 1.322), (3, 1.839), (4, 2.417), (5,3.012), (6, 3.613)

<u>Using an online calculator found the equation of the regression line:</u>

  • y = 0.576x + 0.139

<u>In our case it is:</u>

  • log y = 0.576x + 0.139

Use the numbers shown to make the equations true. Each number can be used only once.
Lisa [10]

Answer:

a. √64=8

b. ∛1000=10

Step-by-step explanation:

64=8^2 Therefore, √64=8

1000=10^3 As a result, ∛1000=10

64=4^3 but each number can only be used once, so this is not possible answer.

Solve the following equation. Round solution to the tenths place.<br> 29 = с/7.2<br> C =
expeople1 [14]

Answer:

c = 208.8

Step-by-step explanation:

a. \frac{c}{7.2} =29   <em>To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.</em>

b.  \frac{c}{7.2} =29   <em>You need to move the 7.2 to the other side. So, </em><em>multiply</em><em> both sides by 7.2, because it's being divided, so multiplying will cancel it out.</em>

c:  c = 29 * 7.2   <em>Then, multiply 7.2 by 29. (The * symbol means multiply)</em>

d.  c. = 208.8   <em>The answer is 208.8, which is rounded to the tenths place.</em>

Hope this helps! I tried to explain it in detail. :)

Simplify.<br> (-2u?+u-3)+(4u²+7u+5)
Pavlova-9 [17]

Answer:

2u^2+8u+2

Step-by-step explanation:

\left(-2u^2+u-3\right)+\left(4u^2+7u+5\right)

\blacksquare <u>Remove parentheses:</u>

\longmapsto -2u^2+u-3+4u^2+7u+5

\blacksquare <u>Combine like terms:</u>

-2u^2+4u^2+u+7u-3+5

\longmapsto -2u^2+4u^2=2u^2

\longmapsto\:u+7u=8u

\longmapsto -3+5=2

\leadsto 2u^2+8u+2

Jocelyn and Madelyn go to the movie theater and purchase refreshments for their friends.
Alik [6]

let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:

2p + 3d = 18.25

4p + 2d = 27.50

From this, we can use substitution or elimination to solve:

For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.

For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.

I'll be using elimination in this case:

-2(2p + 3d = 18.25) --> -4p - 6d = -36.50

-4p - 6d = -36.50

4p  + 2d = 27.50

-4d = -9.00

d = 2.25

4p + 2 * 2.25 = 27.50

4p + 4.50 = 27.50

4p = 23.00

p = 5.75

Now let's check our answer:

2 * 5.75 + 3 * 2.25 = 18.25

11.50 + 6.75 = 18.25

18.25 = 18.25

So drinks cost $2.25 and popcorn $5.75
