Answer:
1.5 OR 1 1/2
Step-by-step explanation:
Convert the fractions into decimals.
9/10 = 0.9
3/5 = 6/10 = 0.6
Divide the decimals.
0.9/0.6 = 1.5
Convert back to fraction.
1.5 = 1 1/2
We have to find t(theta) in radians.
cos t = cos 65° + cos 55°
We know that:
cos x + cos y = 2 · cos (x+y)/2 · cos (x - y)/2
cos t = 2 · cos (65°+55°)/2 · cos (65°-55°)/2
cos t = 2 · cos 60°· cos 5°
cos t = 2 · 1/2 · cos 5°
cos t = cos 5°
t = 5° = π/36 radians
Answer:
An independent event is an event in which the outcome isn't affected by another event. A dependent event is affected by the outcome of a second event.
Answer:
1 < x < 3
(1 , 3)
Step-by-step explanation:
We have been provided with a set that is
{x|1 < x < 3}
We have to write it in both as an inequality and also in the form of interval notation.
The inequality can be found easily by just looking at the given set. It states that the set contains x, such that x is greater than 1 and x is smaller than 3, so the inequality can be written as:
1 < x < 3
To write in interval notation, we use brackets, As both 1 and 3 are not included, we'll use round brackets to show the interval.
(1 , 3)
C . 4
3+2+7=12
12 divided by 3 equals 4.
Hope this helps!
