Answer:
a) 1/10
b) 110
Step-by-step explanation:
A) we start by getting the total number of rolls
That would be;
11 + 22 + 7 + 8 + 13 + 19 = 80
The frequency of getting a 4 is 8
The probability that the next roll will be a 4 is;
8/80 = 1/10
b) Firstly, we get the probability of getting a 2
We have this as:
22/80
So for 400 rolls, the number of 2’s will be;
22/80 * 400
= 22 * 5 = 110
Answer:
angle 4 = 80 degrees
angle 5 = 100 degrees
Step-by-step explanation:
The answer is 3√5 units
Explain
∠KMJ = 180° - 90° -adjacent angles on a straight line = 90°
Using Pythagora's Theorem
KJ² = 6² + 3²
KJ² = 45
KJ = √45
= √9√5
= 3√5
Answer:
2091 g
Step-by-step explanation:
Multiply the first two factors together, obtaining:
46 1 kg 1000 g
------ * ------ * -----------
2.2 1 kg 1
Reduce the first (fractional) factor:
20.91 * 1000 g = 2091 g
