Answer:

y+8 = 1/5(x+4)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y- -8 = 1/5(x - -4)

y+8 = 1/5(x+4)

brilliants [131]

Answer:

Independent-samples t-test.

Step-by-step explanation:

We are looking for the appropriate design for testing the significance of the difference between the means.

Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.

Thus, the test to be used here is Independent-samples t-test.

lozanna [386]

Answer:

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

Step-by-step explanation:

Given

Given that 74% of the animals at an animal shelter are dogs.

To determine:

About what fraction of the animals at the shelter are dogs?  

Using the equation to find a fraction equivalent to 74%

 \:74\%=\:\frac{74}{100}

Divide numerator and denominator by 2

         =\frac{\frac{74}{2}}{\frac{100}{2}}\:\:

Cancel the common factor 2.

        =\frac{37}{50}

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

The ratio of the heights of two similar pyramids is 3:2. The volume of the larger pyramid is 135 cm3. What is the volume of the
professor190 [17]
If the height Ration is a/b, then

The ration of the arias S₁ & S₂==> S₁/S₂  = a²/b² and
The ration of the volumes V₁ & V₂==> V₁/V₂ =a₃/b₃

V₁ =135 cm³ the ration of the heights = 3/2, Calculate V₂
V₁/V₂ =3³/2³ = 27/8===> 135/V₂ = 27/8==> V₂=(135x8)/27 = 40cm³
