Hey!

Circumference of a circle ⇒ π · d

 d = 24

24 · π = 75.4 = 75

Answer ⇒ C. 75 cm

Hope this helps! :)

<u>Answer</u>

√7 × √5

√3 × √2


<u>Explanation</u>

√9*√16   = 3 × 4

              = 12

             = 12/1      ⇒ It is a rational answer.

√7*√5  = √(7×5)

            = √35

           = 5.916079783.... ⇒ Irrational

√3*√2  = √(3×2)

           = √6

            = 2.449489743...  ⇒  Irrational

4√2*√2 = 4 × √(2×2)

              = 4 × √4

              = 4 × 2

              = 8

              = 8/1   ⇒  It is rational

The expressions that would give irrational answers are: √7*√5  and√3*√2

The null hypothesis claims that the proportion of community college students who work full-time is 0. 45. The alternative hypoth
diamong [38]

The stronger the evidence is against the null hypothesis, the higher the divergence from it.

What do you mean by null hypothesis ?

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory' veracity. It is sometimes referred to as just "the null," and its symbol is H_{0}. To determine if a theory regarding markets, investing methods, or economies is correct or wrong, quantitative analysts employ the null hypothesis,

The null hypothesis states that the percentage of the population who works full time is 0.45.

As a result, 450 persons who are randomly selected from a population of 1000 work full-time.

A different hypothesis states that the ratio is higher than 0.45.

In the options provided, the proportion for the first option is 300/1000, or 0.3.

In the second choice, 500/1000 equals 0.5

Third alternative: 700/1000 = 0.7

Therefore, the stronger the evidence is against the null hypothesis, the higher the divergence from it.

To learn more about the null hypothesis from the given link.

The correct answer is:  "(-1, -2)" .
________________________________________
Note:  By examining the point of intersection of the lines of the 2 graphs show in the "image attached", we can see that the point of intersection is at:  "(-1, 2");  that is:  "x = -1, y = 2" .

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula
9966 [12]

The percent increase of the second year was 85.71%

Step-by-step explanation:

The exponential growth formula is y=a(1+r)^x

where;

y=population after x years

a=original population

r=growth rate as a decimal

x=number of time interval that have passed

Let starting population be p

The first year increase in the population was 40% this means;

r=0.4 , x=1 and a=p thus the equation will be

y=p(1+0.4)^1 ⇒⇒y=1.4 p

In the second year the population of birds of an island became 7 times more than before which is 7p

7p= 7*1.4p= 9.8p

Increase will be;

9.8p-1.4p=8.4

% increase will be;

8.4/9.8 *100 =85.71%
