Answer:

You need to write log_2 80 in terms of log_2 5 , such that:

log_2 80 = log_2 (8*10)  

Using the properties of logarithms, you need to convert the logarithm of product in summation of logarithms, such that:

log_2 (8*10)= log_2 8 + log_2 10

Since log_2 10 = log_2 (2*5) , yields:

log_2 (8*10)= log_2 8 + log_2 (2*5)

log_2 (8*10)= log_2 8 + log_2 2 + log_2 5

You need to write 8 as power of 2, such that:

log_2 (8*10) = log_2 (2^3) + log_2 2 + log_2 5

Using the power property of logarithms, log_a b^c = c*log_a b  yields:

log_2 (8*10) = 3log_2 2 + log_2 2 + log_2 5

Since log_2 2 = 1 yields:

log_2 (8*10) = 3 + 1 + 2.3219

log_2 (8*10) = 4 + 2.3219 => log_2 (8*10) = 6.3219

Hence, evaluating the given logarithm , using the indicated properties of logarithms, yields log_2 (8*10) = 6.3219 .

Step-by-step explanation:

The value of [tex]log_2{80}[/tex] if [tex]log_25 = 2.3219[/tex] is 6.3219.

The logarithm is exponentiation's opposite function in mathematics.

This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

Given, [tex]log_25 = 2.3219[/tex].

Now, To obtain the value of [tex]log_2{80}[/tex] we'll break it into suitable smaller parts.

Therefore,

[tex]log_2{80} = log_2({8\times10})[/tex].

[tex]log_2{80} = log_28 + log_210[/tex]

[tex]log_2{80} = log_28 + log_2({2\times5})[/tex].

[tex]log_2{80} = log_28 + log_22 + log_25[/tex].

[tex]log_2{80} = 3 + 1 + 2.3219[/tex].

[tex]log_2{80} = 6.3219[/tex].

The scatterplot that best represent a linear relationship between the variables, X and Y, is: graph C.

On a scatterplot, the trendline that shows a linear relationship between two variables will have a straight line pattern that either slopes up or down.

The scatter plot in graph C shows a trendline that slopes along a straight line. Therefore, the answer is C.

Step-by-step explanation:

Answer:

we conclude that when we substitute b = 15, the solution of the inequality becomes:

[tex]a>-3[/tex]

Therefore, the value of b = 15.

The solution graph is also attached.

Step-by-step explanation:

Given the inequality expression

[tex]a+b>12[/tex]

Putting b = 15 in the inequality expression

[tex]a+b>12[/tex]

[tex]a+15>\:12[/tex]

subtract 15 from both sides

[tex]a+15-15>12-15[/tex]

simplify

[tex]a>-3[/tex]

Thus, we conclude that when we substitute b = 15, the solution of the inequality becomes:

[tex]a>-3[/tex]

Therefore, the value of b = 15.

Answer:

50%

Step-by-step explanation:

Most people assume the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails

Answer:

100%

Step-by-step explanation:

There is a 50% chance of getting heads, and 50% chance of getting tails.

If these two options are added together, you get 100%. There are only two options on a coin flip anyways, so the probability of getting heads or tails would be 100%.

Goal = > $2500

Amount raised = $700

Amount needed to raise = $2500 - 700 = $1800

Number of candy bars needed = x

Price of a candy bar = $1.50

1.5x > 1800

x > 1800 ÷ 1.5

x > 1200

Answer:

x = 40

Step-by-step explanation:

I don't understand, but I think you mean 2x + 20 = x + 60

So that's what I'm going to solve for if that's wrong tell me what you mean.

2x + 20 = x + 60 (subtract 20 on both sides)

2x = x + 40 (subtract x on both sides)

x = 40

Answer:

y = -32

Step-by-step explanation:

-6 (y+15) = -3y + 6

-6y - 90 = -3y + 6

-3y - 90 = 6 + 90

= -3 = 96

y = -32

Answer:

Y=28

Step-by-step explanation:

Distribute-6(y+15) > -6y-90

-6y-90=-3y+6 add the -3y to the -6y and the -90 to the 6

-3y=-84

Then just divide -84 by -3
