Answer:
Hypothesis
Step-by-step explanation:
Hypothesis:
- It is an assumption or explanation that need to be tested.
- It determines the claim in the testing.
- There are two types of hypothesis: Null hypothesis and alternate hypothesis.
- Null hypothesis says that the sample is taken from the population.
- Alternate hypothesis states that the sample does not belong to the defined population.
A hypothesis is a testable claim or statement, that is yet to be tested, concerning the relationship among variables that can be observed.
Answer:
d.
Step-by-step explanation:
24/(3/4) = 32
24/ (6/5) = 20
24/(4/15) = 90
Answer:
0.6778 to 4 dec. places.
Step-by-step explanation:
That is 387 / (184+387)
= 387 / 571
= 0.677758
Answer:
62° and 96°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 remote interior angles.
Let x be the other remote interior angle, then
22 + x = 84 ( subtract 22 from both sides )
x = 62
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 known angles from 180 for third angle
third angle = 180 - (62 + 22) = 180 - 84 = 96
The other 2 interior angles are 62° and 96°
Hi there!
We know that the equation for the volume of a pyramid is:
V = 1/3(bh)
We know that:
V = 200 km³
b = 12 × 5 = 60 km²
We can plug these into the equation:
200 = 1/3(60)(h)
Simplify:
200 = 20h
Divide both sides by 20:
200/20 = 20h/20
h = 10 km
