R=26, you can use cross multiplication to figure this proportion out. 22 times 13 is 286 and 11 times r is 11r , leaving you with 286=11r. you would then divide each side by 11 to isolating the variable giving you r=26.
area of the opening 14.93 sq. inch.
From this statement "the area of the opening may be expressed as the function: a(θ) = 16 sin θ ⋅ (cos θ + 1).
if θ = 30°
We can substitute 30° in the expression a(θ) = 16 sin θ ⋅ (cos θ + 1) to get the area of the opening.
The area of the opening = 16 sin 30 ⋅ (cos 30 + 1)
= 16x0.5 (0.866 + 1)
= 8(1.866)
= 14.93 sq. inch.

Answer: 1/1024
Step-by-step explanation:
When a fair coin is flipped the coin would show either head or tail meaning only 2 outcomes are possible. So, getting an head means 50% chance or 1/2 chance.
Now, it means chance for 10 times head every time= (1/2)^10
Chance= 1/1024
Chance= 0.00097
Answer:
Matched sample design
Step-by-step explanation:
- A matched subject design uses separate experimental groups for each particular treatment, ( A sample of brothers and sisters - genders ).
- But relies upon matching every subject in one group with an equivalent in another. (The differences in ratings between each brother and sister pair were compared. )
- The idea behind this is that it reduces the chances of an influential variable skewing the results by negating it.
Answer:
4y + 3
Step-by-step explanation:
All we can do here is to simplify the given expression; this is not an equation and thus has no solution.
5y - y is 4y, so
5y - y + 3 = 4y + 3
