Answer:
1. false
2. 17 times
Step-by-step explanation:
The sum of all the probabilities of outcomes of an event is equal to 1
2. A die has 1,2,3,4,5,6
P(4) = number of 4's/ total numbers
= 1/6
Multiply the number of roll's by the probability of getting a 4
100 *1/6 = 50/3 = 16 2/3
This is approximately 17
The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.
<h3 /><h3>How to get the angle in radians?</h3>
Remember the relation:
180° = 3.14 radians.
Then:
60° = (60°/180°)*3.14 rad = 1.05 rad.
Now, for a circle of radius R, an arc defined by an angle θ has a length:
L = θ*R
Then the length of this arc is:
L = 1.05*1 unit = 1.05 units.

Answer:
The one which has a height of 3 units. H=3
Step-by-step explanation:
Well, the volume of pyramid is equal to the area of base multiply by the height of pyramid and divide by 3. Writing as a formula it can be expressed as V=(A*H)/3 where V is volume of pyramid, A is area of base and H is the height of pyramid. If V=15 cubic units and A=15 square units, H should be equal to 3 (to be cancelled out by 3. Please look at formula above) in order to make V=15.
The answer would be 180 degrees
