Identify the graph described by the function p(x)=x/10 for x=1,2,3,4

san4es73 [151]

Answer:

Graph A is correct

Step-by-step explanation:

p(x)= x/10

x= 1, 2, 3, 4

Plug in x values in p(x)

when x=1 , then P(1) = 1/10

When x=2 , then P(2) = 2/10

When x=3 , then P(3) = 3/10

When x=4 , then P(4) = 4/10

In the graph y axis has 2/10 , 4/10 , 6/10...

1/10 lies between 0 and 2/10

3/10 lies between 2/10 and 4/10

Graph A is correct

A new experimental strain of pepper plants was being studied to estimate how much fruit one plant would produce in a typical gro

zmey [24]

Answer:

58.9% produced produced peppers weighing between 13 and 16 pounds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 15

Standard Deviation, σ = 1.75

We are given that the distribution of weight of peppers is a bell shaped distribution that is a normal distribution.

Formula:

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

P(peppers weighing between 13 and 16 pounds)

$P(13 \leq x \leq 16) = P(\displaystyle\frac{13 - 15}{1.75} \leq z \leq \displaystyle\frac{16-15}{1.75}) = P(-1.142\leq z \leq 0.571)\\\\= P(z \leq 0.571) - P(z < -1.142)\\= 0.716 - 0.127 = 0.589 = 58.9\%$

$P(13 \leq x \leq 16) = 58.9\%$

58.9% produced produced peppers weighing between 13 and 16 pounds.
