Answer:

Area of geometric figures mentioned calculated.

Step-by-step explanation:

Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5

Area of square = ( Side )^2 = ( 5 )^2 = 25

Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25

Which number can be used as a common denominator for the fractions One-fourth and FIve-sixths?

Sav [38]

Answer:

Step-by-step explanation:

Given two fractions:

One - fourth and Five - Sixths.

To find:

The common denominator that can be used for the given fractions.

Solution:

First of all, let us have a look at the given fractions:

First fraction is:

$\dfrac{1}{4}$

Second fraction is:

$\dfrac{5}{6}$

The denominators of the fractions are 4 and 6.

To find a common denominator, we need to take LCM (Least Common Multiple) of the two denominators.

LCM is the least number which is divisible by the two numbers.

Let us find the LCM by factorization method.

4 = 2 $\times$ 2

6 = 2 $\times$ 3

The common number are taken once and other number which are not common are taken as it is.

So, the LCM is 2 $\times$ 2 $\times$ 3 = 12

The numbers can be written as:

$\dfrac{3}{12}, \dfrac{10}{12}$

Therefore, 12 can be used as the common denominator.

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.
