It is believed that sunlight offers some protection against multiple sclerosis (ms) since the disease is rare near the equator and more prevalent at high latitudes. what is it about sunlight that offers this protection? to find out, researchers23 injected mice with proteins that induce a condition in mice comparable to ms in humans. the control mice got only the injection, while a second group of mice were exposed to uv light before and after the injection, and a third group of mice received vitamin d supplements before and after the injection. in the test comparing uv light to the control group, evidence was found that the mice exposed to uv suppressed the ms-like disease significantly better than the control mice. in the test comparing mice getting vitamin d supplements to the control group, the mice given the vitamin d did not fare significantly better than the control group. if the p-values for the two tests are 0.472 and 0.002, which p-value goes with which test?

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
