Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A = (14 × 4) = 28
Answer:
72.1 cm
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle and is in radians (not degrees).
Here we convert 140° to radians: 140°(π/180°) = 2.44 radians.
Then the desired arc length is s = rФ = (29.5 cm)(2.44 radians) = 72.1 cm
Answer:
2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
= 4.22×3×3.15576/1.609344×10^(8+7-3) mi
≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
The <em>correct answer</em> is:
Independent.
Explanation:
The criteria for binomial experiments are:
A fixed number of trials.;
Each trial is independent of the others.;
There are only two outcomes; and
The probability of each outcome remains constant from trial to trial.
This means the outcomes are constant and independent.
