The rate of change is 4 due to the fact that each increase is on the graph is by a factor of 4 cm and each horizontal increase is 1 week, therefore we can also conclude that the plant grows 4cm in 1 week

Therefore the correct answers are
- The rate of change is 4
- The plant grows 4cm in 1 week

y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

$-14-(42) =-14+42 =28\\14+14= 28$

The change in y is:

$-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56$

The slope is:

$Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2$

Putting slope in equation of linear function

$y =2x+b$

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

$28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0$

Hence,

the linear equation for function is:

y = 2x

a cooler contains 50 bottles; 30 bottles of water, which 8 are lemon flavored and 20 bottles of tea, of which 5 are lemon flavor

xenn [34]

Answer:

The required probability is $\dfrac{13}{50}$

Step-by-step explanation:

Total number of bottles = 50

Total number of water bottles = 30

Total number of lemon flavored water bottles = 8

Total number of tea bottles = 20

Total number of lemon flavored tea bottles = 5

Probability of selecting a lemon flavored water bottle = Probability of selecting a water bottle $\times$ Probability of selecting a lemon bottle out of water bottles.

Probability of selecting a lemon flavored tea bottle = Probability of selecting a tea bottle $\times$ Probability of selecting a lemon bottle out of tea bottles.

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$
