How do you find the area of an irregular figure

timama [110]

To find the area of irregular shapes, the first thing to do is to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth... Then, find the area of these individual shapes and add them up! That's what i found online, hope it helps!

4. In Problem 2, you were told that the durations of high school baseball games are approximately normally distributed with a me

gregori [183]

Answer:

It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes

Step-by-step explanation:

We are given the following information in the question:

Basket ball game:

Mean, μ = 105 minutes

Standard Deviation, σ = 11 minutes

Softball game:

Mean, μ = 95 minutes

Standard Deviation, σ = 11 minutes

We are given that the distribution of durations of high school baseball games is a bell shaped distribution that is a normal distribution.

Formula:

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

P(basketball game will last between 100 and 110 minutes)

$P(100 \leq x \leq 110) = P(\displaystyle\frac{100 - 105}{11} \leq z \leq \displaystyle\frac{110-105}{11}) = P(-0.454 \leq z \leq 0.454)\\\\= P(z \leq 0.454) - P(z < -0.454)\\= 0.675 - 0.325 = 0.35$

P(softball game will last between 100 and 110 minutes)

$P(100 \leq x \leq 110) = P(\displaystyle\frac{100 - 95}{11} \leq z \leq \displaystyle\frac{110-95}{11}) = P(0.454 \leq z \leq 1.363)\\\\= P(z \leq 1.363) - P(z < 0.454)\\= 0.914 - 0.675 = 0.239$

Since,

P(basketball game) > P(softball game)

It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes
