Step-by-step explanation:
In my opinion Option A is the correct answer because
Product of 3 and x = 3x
7.5 more than that = 3x + 7.5
Answer:
31/100
Step-by-step explanation:
From the given table
Reading books percentage is 22
so Probability (reading books) = 
Surf the internet percentage is 9
Probability (surf the internet) =
the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)
probability (reading or surf)= 
= 
You add the numbers 69 and 59 and you get your angle measure.

Answer:
Cos θ = √7/3
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine θ = √2 / 3
Cos θ =?
Recall
Sine θ = Opposite / Hypothenus
Sine θ = √2 / 3
Thus,
Opposite = √2
Hypothenus = 3
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = √2
Hypothenus = 3
Adjacent =?
Hypo² = Adj² + Opp²
3² = Adj² + (√2)²
9 = Adj² + 2
Collect like terms
9 – 2 = Adj²
7 = Adj²
Take the square root of both side
Adjacent = √7
Finally, we shall determine the value Cos θ. This can be obtained as follow:
Adjacent = √7
Hypothenus = 3
Cos θ =?
Cos θ = Adjacent / Hypothenus
Cos θ = √7/3
