Answer:
There are 7 chairs in each row.
Step-by-step explanation:
Hue is arranging some number of chairs. If she arranges them in 6 rows of equal lengths then there will be 3 chairs leftover, or she arranges them in 8 rows of that same length then she requires 11 more chairs.
Let us assume that there are P numbers of chairs and there are x chairs in each row.
Therefore, we can write that
6x + 3 = P ....... (1) and
8x = P + 11
⇒ 8x - 11 = P ........ (2)
Now, from equations (1) and (2) we get,
6x + 3 = 8x - 11
⇒ 2x = 14
⇒ x = 7
Therefore, there are 7 chairs in each row. (Answer)
The new width is 16.6666666667 inches, which can be rounded to 16.7.
Width: 5 ?
Height: 6 20
We know that based on the information provided, the new height is 20 inches.
So, in order to solve, you can cross multiply (5 x 20), which would be 100. Then
divide by 6, to get 16.6666666667 or 16.7.
Answer:
a) 1820
b) 55
c) 10
d) 550
e) 0.3022
Step-by-step explanation:
Data provided in the question:
Number of seniors = 11
Number of juniors = 5
n = number of choices
r = number of person to be selected
number of ways = 
a) 4-sprinter relay teams can be formed from the group of 16 sprinters
n = 16
r = 4
= ¹⁶C₄
= 
= 
=
b) two seniors be chosen to be part of the relay team
n = 11
r = 2
= ¹¹C₂
= 
= 
=
c) two juniors be chosen to be part of the relay team
n = 5
r = 2
= ⁵C₂
= 
= 
= 10
d) two seniors and two juniors be chosen to be part of the relay team
= two seniors be chosen to be part of the relay team × two juniors be chosen to be part of the relay team
= 55 × 10
= 550
e) P( two seniors and two juniors will be chosen for the relay team )
= [ two seniors and two juniors be chosen to be part of the relay team ] ÷ [4-sprinter relay teams can be formed from the group of 16 sprinters ]
= 550 ÷ 1820
= 0.30219 ≈ 0.3022
