1/6 acres in 1/4 hour
1/6 * 4 = 4/6 = 2/3
she mows 2/3 acres per hour
Answer:
60 meter
Explanation:
Given following:
hypotenuse: 68 meter
---
tan(θ) ratio = opposite/adjacent = 15/8
---
To find ratio of hypotenuse (use Pythagoras theorem):
(hypotenuse)² = (adjacent)² + (opposite)²
(h)² = (8)² + (15)²
h² = 289
h = √289 = 17
The height of the kite above ground is the opposite size.
Answer:
B
Step-by-step explanation:
equation of a line is in the form of y=mx+b where m is the slope and b is the y intercept
slope: -1-2/0-4 = 3/4
y intercept is when x is 0, so y intercept is -1
therefore the equation of this line is y=3/4x-1
Answer:
For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.
Step-by-step explanation:
Here, P(x > 40) = 0.16
a). P(x < 40) = 1 - P(x > 40)
= 1 - 0.16
= 0.84
b). P(x < 20) = 1 -
= 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}
= 1 - (0.15 + 0.16 )
= 1 - 0.31
= 0. 69
c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.
