Answer:
Step-by-step explanation:
P(A) = 4/52 = 0.07692 which is bigger than 5%
5% = 0.05
0.07 is above 5% which is surprising.
The P(Spade A) = 1/52 = 0.01923 which is under 2% which meets your criteria.
Answer:
11.55
Step-by-step explanation:
An equilateral triangle is one which all it sides are equal.
10cm altitude means the height is 10cm.
Using Pythagoras theorem,
x² = 10² + (x/2)²
Assume that the side of the triangle is xcm
x² - x²/4 = 100
3x²/4 = 100
x = √(400/3)
x = 11.55cm
Answer:
42 units
Step-by-step explanation:
Lengths:
(-2,6)(6,6)
6 - -2 = 8
(1,-6)(-7,-6)
1 - - 7 = 8
(6,6)(1,-6)
sqrt[(-6-6)² + (1-6)²]
sqrt(169) = 13.
(-2,6)(-7,-6)
sqrt[(-6-6)² + (-7--2)²]
sqrt(169) = 13
Perimeter = 8 + 8 + 13 + 13
42 units
Answer:
Option 1
Option 3
Option 4
Step-by-step explanation:
Inversely proportional means "one quantity increases, the other decreases" or "one quantity decreases, other increases". Inverse relationship, that's it.
Option1:
Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice verse. So inversely proportional.
Option2:
The time spend in plowing a field with a tractor will increase when we area using more fuel. So more fuel used means more time spent. So these are directly proportional, NOT inverse.
Option3:
Since the price is at constant, the amount of length we buy more, the price per one yard HAS to decrease, and vice versa. So, this is inverse relationship.
Option 4:
If the number of identical tranctors increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is inversely proportional as well.
