The results of a linear regression are shown below.

IgorLugansk [536]

Hello!

As we can see, our a value, which would be the coefficient of $x$ , which determines our slope, is negative, meaning that this whole line is negative.

Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.

If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.

Buddy, Louis, Mabel and Spot are all puppies and are playing in the forest. They notice seven bees and five cockroaches, and the

Natasha2012 [34]

Answer:

188 legs

Step-by-step explanation:

A game of legs!!

In this question, we are asked to calculate the number of legs of animals present in the question.

Let’s first identify the individual brands of animals present. We have ;

4 dogs, 7 bees, 5 cockroaches, 8 spiders, 3 deers, 4 boars and 2 antlers.

A dog has 4 legs; this means total number of legs contributed by the dogs to the pool will be 4 * 4 = 16 legs

A bee has six legs; total number of bees legs is thus 7 * 6 = 42 legs

A cockroach has 6 legs; total number of cockroaches legs is 6 * 5 = 30 legs

8 spiders have a total of 8 * 8 = 64 legs

3 deers, 4 boars and 2 antlers have 4 legs each making a total of 9 * 4 = 36 legs

The total number of legs present is thus; 36 + 64 + 30 + 42 + 16 = 188 legs

An average adult can hear sounds with frequencies between 20 waves per second and 16,000 waves per second. What is the wavelengt

frez [133]

Answer:

The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.

Step-by-step explanation:

In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.

We know that the speed of light in air/ vacuum is $3\times 10^{8}$ .

Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,

we put the values

$3\times 10^{8}$ = 20 × λ

λ = $\frac{3\times 10^{8}}{20}$

λ = 15,000,000 m
