Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foo

Answer:

See attachment for graph

Step-by-step explanation:

Given

$2 cans = 10ft\ by\ 12ft$

Required

Graph the relationship between both parameters

First, calculate the area;

$Area = 10ft * 12ft$

$Area = 120ft^2$

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{120 - 0}{2-0}$

$m = \frac{120 }{2}$

$m = 60$

The equation is:

$y = m(x - x_1) + y_1$

So, we have:

$y = 60 * (x - 0) + 0$

$y = 60 * (x )$

$y = 60 x$

kompoz [17]

Answer:

The probability that more than 35 were made is 0.14686.

Step-by-step explanation:

We are given that a professional basketball team made 37.9% of its three-point field goals in one season.

80 three-point field goal attempts are randomly selected from the season.

Let $\hat p$ = sample proportion of three-point field goals made in one season.

The z-score probability distribution for the sample proportion is given by;

Z = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}} }$ ~ N(0,1)

where, p = population proprotion of three-point field goals = 37.9% = 0.379

n = sample of three-point field goal attempts = 80

$\hat p$ = sample proportion of three-point field goals = $\frac{35}{80}$ = 0.4375

Now, if 80 three-point field goal attempts are randomly selected from the season, the probability that more than 35 were made is given by = P( $\hat p$ > 0.4375)

P( $\hat p$ > 0.4375) = P( $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}} }$ > $\frac{0.4375-0.379}{\sqrt{\frac{0.4375(1-0.4375)}{80}} }$ ) = P(Z > 1.05) = 1 - P(Z $\leq$ 1.05)

= 1 - 0.85314 = 0.14686

The above probability is calculated by looking at the value of x = 1.05 in the z table which has an area of 0.85314.
