10² ,+ 14² = 26²?
100+ 196 = 676?
they do not meet the Pythagorean criterion a² + b²=c so they are not a triple
10 x 90.3 = 903
10 x 90.6 = 906
When finding the missing number to 121 + ? = 968, all you have to do is subtract 121 from 968 to get your answer.
968
-121
———
847
121+847=968
Answer:
subtract 20 from both sides
Step-by-step explanation:
1. To find the answer, let's actually try solving the equation first and find the 2nd step.
2. (Solving)
Step 1: Distribute 2 to each term.
Step 2: Subtract 20 from both sides.
3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.
Answer:
the probability of getting exactly 2 fours is 0.16
Step-by-step explanation:
The probability of obtaining a number that is four = ¹/₆
The probability of obtaining a non 4 number = 1 - ¹/₆ = ⁵/₆
The number of ways 2 fours can be arrange in five numbers = ⁵C₂ = 10 ways
If the die is tossed five times, the probability of the events is calculated as;
P = 10 x (¹/₆)² x (⁵/₆)³
P = 10 x (¹/₃₆) x (¹²⁵/₂₁₆)
P = 10 x 0.02778 x 0.5787
P = 0.16
Therefore, the probability of getting exactly 2 fours is 0.16
