Answer:

y=20x+40

Step-by-step explanation:

y represents how many gallons of water he used

x represents the amount of days

(example) if he watered his plants for 2 days:

y=20(2)+40

y=40+40

y=80

if he watered his plants for 2 days he would have used 80 gallons of water.

if this helped please rate, thanks, and mark brainliest :)

The stock price for International Business Machines (IBM) historically has followed an approximately normal distribution (when a

olganol [36]

Answer:

0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $188.876

Standard Deviation, σ = $4.6412

We are given that the distribution of stock price is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(stock price is between $186.26 and $192.47)

$P(186.26 \leq x \leq 192.47) = P(\displaystyle\frac{186.26 - 188.876}{4.6412} \leq z \leq \displaystyle\frac{192.47-188.876}{4.6412}) = P(-0.5636 \leq z \leq 0.7743)\\\\= P(z \leq 0.7743) - P(z < -0.5636)\\= 0.781 - 0.287 = 0.494 = 49.4\%$

$P(186.26 \leq x \leq 192.47) = 49.4\%$

0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.

A pizza is to be cut into halves. Each of these halves is to be cut into sevenths. What fraction of the pizza is each of the fin

Hitman42 [59]

Answer: $\dfrac{1}{14}$

Step-by-step explanation:

Given, A pizza is to be cut into halves.

Since half is represented by $\dfrac12$ .

So each piece is now $\dfrac12$ of the original.

if each of these halves is to be cut into sevenths, then the fraction of final pieces would be: $\dfrac{1}{2}\times\dfrac{1}{7}=\dfrac{1}{14}$ or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.

And the fraction of the pizza is each of the final pieces = $\dfrac{1}{14}$ .
