You replace x with (a+1)
Then f(a+1) = (a+1)^2+1
= a^2+2a+1+1
= a^2+2a+2

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.

Need helppp on this question!!

I’m pretty sure it would be f(x)= -5/2x-8
You can honestly plug it into a graph yourself or you can get the formula and solve it like that. Unfortunately I do not have the formula on hand. Sorry

A baseball team played 32 question games and lost eight can use the catcher in 5/8 of the winning games in 1/4 of the losing gam

Westkost [7]

Answer:

3/4

Step-by-step explanation:

From this question we have that this team played 32 games.

They lost 8 out of these 32 games

So their total wins = 32 - 8 = 24

Therefore the fraction of their win would be = win / total number of games played

= 24/32

When reduced further

24/32 = 3/4

Therefore the fraction of games which the team won = 3/4

Thank you!
