The graph shows how much a plant grew after it was purchased. Which statement is not correct?

Luda [366]

Answer:

The plant grows 1 cm every day is the incorrect statement

Step-by-step explanation:

The graph shows that for every 10 days the plant grows 1 cm

10/2 = 5

so in 5 days the plant would grow half of what it does in 10 days so 1/2 or 0.5 cm

10/10 = 1

so in 1 day the plant would grow a tenth of what it does in 10 days so 1/10 or 0.1 cm

stellarik [79]

Figure out 5% of 30,000: .05 x 30,000 = 1,500

Multiply 1,500 by the number years, but subtract the first year (as you don't receive a bonus) : 1,500 x 39 = 58,500

Now add the bonus with the initial salary: 58,500 + 30,000 = 88,500.

THE ANSWER IS $88,500!!! :)

Answer:

D.No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Step-by-step explanation:

(a) Range is the difference between the smallest and largest observation.

Here Smallest observation = 0.63

and Largest observation = 1.48

⇒ Range = 0.85

(b) Standard Deviation is calculate by,

$Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }$

where, $\bar{x}$ is mean of the observation.

Here, Mean = 0.988

⇒ Standard Deviation = 0.313

(c) Variance is the square of Standard deviation.

Thus, Variance = (Standard Deviation)² = 0.098

(d) Here last option(D) is true i.e. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.
