AleksAgata [21]

Answer:

Only 5

Step-by-step explanation:

You just place each in. The one that fits in the equation is the right one.

11-5=6 and 6 is less than 7.

11-3=8 and 8 is greater so it doesn't work.

Researchers wanted to study if having a long beak is related to flight and birds they surveyed a total of 34 birds the data are
vovangra [49]

The odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76.

<h3>What is an odds ratio?</h3>

An odds ratio is a measure of the strength of an association with the exposure and outcome.

The odds ratio can be calculated by dividing the odds of the first group (exposure) by the odds of the second group (outcome).

                             Flies      Does not fly     Total

Long beak               11               7                     19

Not a long beak      3              13                     15

Total                       14             20                    34

Probability of long beaks flying = 0.79 (1/14)

Probability of not having long beaks flying = 0.21 (3/14)

Odds ratio = 3.76 (0.79/0.21)

Thus, the odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76, showing greater odds of association.

Hugh and his brothers are on a road trip. His brother makes a table comparing how long they have traveled in hours ( x ) with th
maksim [4K]

The required equation that can be used to figure out how many miles Hugh and his brothers have traveled based on the number of miles they have driven is y = 65x

<h3>Equation of a graph and table</h3>

Given the following variables

Time taken to travel is x

Mils traveled is y

Using the coordinate points (2, 130) and (4, 260)

The standard linear equation is y = mx + b

slope m = 260-130/4-2
m = 130/2

m = 65

For the intercept

130 = 65(2) + b

b = 0

The required equation that can be used to figure out how many miles Hugh and his brothers have traveled based on the number of miles they have driven is y = 65x
