Hey the probability of getting head all four time is 2/4
-28 < 2x - 10 < -10.....add 10 to all sections
-28 + 10 < 2x - 10 + 10 < -10 + 10....simplify
-18 < 2x < 0...divide all sections by 2
-18/2 < 2/2x < 0/2...simplify
-9 < x < 0 <===
Answer:
Step-by-step explanation:
<u>Let the integers be:</u>
<u>Their sum is 42:</u>
- x + x + 1 + x + 2 = 42
- 3x + 3 = 42
- 3x = 39
- x = 13
The numbers are: 13, 14 and 15
Answer:
12.57
Step-by-step explanation:
the formula for the area of a circle is
the diameter is 2 times the radius, so dividing it by 2 gives you a radius of 2
substitute the 2 for the r in the formula and solve
4
≈12.57
