Answer:
where x denotes number of small rooms and y denotes number of large rooms
Step-by-step explanation:
Given: Small rooms can hold 3 people, and large rooms can hold 4 people.
Number of small rooms is twice the number of large rooms.
Small rooms and large rooms altogether can accommodate 70 guests.
To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved
Solution:
Let x denotes number of small rooms and y denotes number of large rooms.
As number of small rooms is twice the number of large rooms,

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,

Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
