To determine which of the graphs' slope is greater, we need to figure out what the slope for each graph in order to compare them.

Slope Formula: rise/run

For Water's Edge Rafts, let's use the two coordinates (1.6) and (6,36).

Then, once we have our coordinates, we can plug it into the slope formula to find the slope.

36 - 6 / 6 -1 = 30/5

30/5 = 6

The slope for Water's Edge Rafts is 6x.

Also, there is no y-intercept or (b) since it began at the origin.

Next, let's find the slope of Ryan's Rafts.

For Ryan's Rafts, let's use the coordinates (1,15) and (2,17.25)

Same thing, plug it into the slope formula.

17.25 - 15 / 2 - 1 = 2.25/1

2.25/1 = 2.25

The slope for Ryan's Rafts is 2.25x

Therefore, Water's Edge Rafts has a greater slope than Ryan's Rafts.

Answer:

The value of test statistic is -4.1247

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $3.26 a gallon

Sample mean, $\bar{x}$ = $3.19 a gallon

Sample size, n = 32

Sample standard deviation, σ = $0.096

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 3.26\text{ dollars a gallon}\\H_A: \mu < 3.26\text{ dollars a gallon}$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{3.19 - 3.26}{\frac{0.096}{\sqrt{32}} } = -4.1247$

Thus, the value of test statistic is -4.1247

One card is selected at random from a deck of card. Determine the probability that the card selected is not a 4

Ganezh [65]

Answer:

12/13

Step-by-step explanation:

A probability is the number of desired outcomes over the total number of outcomes.

Assuming that this is a standard deck of playing cards, there will be 52 cards, and there will be 4 "4" cards.

First, find the number of desired outcomes, and put it over the total number of outcomes.

Out of the total number of outcomes (52), there are 4 outcomes that are not wanted, hence the equation is:

52 - 4 = 48

So out of the 52 possible outcomes, 48 are desired. Set up the fraction and

simplify:

48/52

/4 /4

= 12/13
