Answer:

Step-by-step explanation:

The cosine of a right triangle is the adjacent over the hypotenuse. If the cosine is -3/5 then it must be a right triangle with sides 3, 4, & 5 since this is a Pythagorean triple. This means the sin will be -4/5. We know its negative because the tangent is positive so this is the 3rd quadrant where both Sine and Cosine are negative.

Mila [183]

Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Step-by-step explanation:

if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.

SD= 9.9

HC= 11

so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.
