Given there are equal amounts of each color and four colors in total, the probability is calculated out of four. As there's an equal quantity of both red and blue, the chance of drawing either a red or blue marble is 2/4.

Solve the equation.<br><br> y + 6 = –3y + 26<br><br> y = –8<br> y = –5<br> y = 5<br> y = 8
zzz [12365]
In this situation, we start with the following equation: To isolate the value of y, we follow these steps: First, we subtract 6 from both sides of the equation: Second, we take away "y" from each side: Third, we add 4y to both sides of the equation: Finally, we divide the equation by 4. Thus, y equals 5. Answer: Option C.

Brandon purchased a new guitar in 2012. The value of his guitar, t years after he bought it, can be modeled by the function A(t)
Zina [12379]

Answer: The guitar's value over time is described by the 0.95 metric, indicating a 5% annual depreciation.

Step-by-step explanation:

To address this inquiry, we use an exponential decay formula:

A = P (1 - r) t

Where:

P = initial price

r = the reduction rate (expressed as a decimal)

t = time in years

A = price after t years

Substituting the known values:

A(t)=145(0.95)t.

Where

0.95 = 1-r

0.95-1 = r

-0.05 = -r

0.05 = r

Converted to percentage:

0.05 x 100 = 5%

Please reach out if further clarification is needed or if something was unclear.

The table shows the estimated number of lines of code written by computer programmers per hour when x people are working.
Zina [12379]

Answer:

Therefore, the data is best represented by:

y=26.9x-1.3

Step-by-step explanation:

We have a table indicating the estimated lines of code produced by computer programmers per hour when x individuals are engaged.

The question asks which model accurately reflects this data.

To determine this, we will substitute the values of x into each function to see which one accurately produces the corresponding y (f(x)) values provided in the table:

We are presented with four functions, which are:

A)

y = 47(1.191)^x

B)

y=34\times (1.204)^x

C)

y=26.9x-1.3

D)

y=27x-4

We'll create a table displaying these values at various x levels.

x                  A                 B                C               D

2              66.66          49.3            52.5           50

4             94.57            71.44           106.3         104  

6             134.14           103.57         160.1          158

8             190.27          150.14          213.9         212

10           269.91           217.64         267.7         266

12           382.85          315.5           321.5          320.

Thus, the function that suitably represents the data is:

Option C.

y=26.9x-1.3
