Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very sl

ow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.

The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.

An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.

In this experiment;

  • The independent variable is the type of dog food
  • The dependent variable is the eating time of the dog
  • The predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foods
  • The control variable is the quantity of dog food given to the dog each evening.
  • The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.

A wildlife biologist is investigating a sudden increase in the death rate
Ann [662]

Answer:

circulatory and respiratory

Explanation:

The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.

When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.

Thus, circulatory and respiratory is the correct answer.

That's D. Viral Reproduction.

It's not A cuz those are not bacteria

It's not B cuz diffusion deals with passive transport across membranes

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given
alexandr402 [8]

Use the slope-intercept form to find the slope.

Tap for fewer steps...

The slope-intercept form is  

y = m x + b  

where  m  is the slope and  b  is the y-intercept.

y = m x + b  

Using the slope-intercept form the slope is  

− 4 . m = − 4

To find an equation that is parallel to  

y = − 4 x + 2

the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

( − 2 , 5 ) m = − 4

Using the point-slope form  

y − y 1 = m ( x − x 1 )

plug in  

m = − 4 ,  x 1 = − 2

and  

y 1 = 5 . y − ( 5 ) = ( − 4 ) ( x − ( − 2 ) )

Solve for  

y .

Multiply  

− 1  by  5 . y − 5 = ( − 4 ) ( x − ( − 2 ) )

Simplify  

( − 4 ) ( x − ( − 2 ) ) .

Multiply  

− 1  by  − 2 . y − 5 = − 4 ( x + 2 )

Apply the distributive property.

y − 5 = − 4 x − 4 ⋅ 2

Multiply  − 4  by  2 . y − 5 = − 4 x − 8

Move all terms not containing  

y  to the right side of the equation.

Add  

5

to both sides of the equation.

y = − 4 x − 8 + 5  Add  − 8  and  5 . y = − 4 x − 3

HOPE THIS HELPED!
