6. A restaurant can seat 100 people. It has booths
1 answer:
<u>Answer:</u>
The expression matches the situation is 4x + 6y = 80
<u>Explanation:</u>
We are given a total of 100 seats which is the maximum amount a restaurant can seat
And there are booth with 4 and table with 6 seating
so let no. of 4 seat booths be x and tables with 6 seats be y
We can form the equation as 4x + 6y = 100
We are also given that 5 of the 4 seat booths are full so this means
45 = 20 seats out of 100 are full
so left ones can be written in the form of an expression 4x + 6y = 80

Answer:
The correct option is C: the isotope of iodine contains 81 neutrons.
Step-by-step explanation:
The mass (A) of the iodine isotope is given by:
Where:
Z: is the number of protons
N: is the number of neutrons
For iodine Z= 53, so if A = 134 the number of neutrons is:
Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

Answer:
a) A response of 8.9 represents the 92nd percentile.
b) A response of 6.6 represents the 62nd percentile.
c) A response of 4.4 represents the first quartile.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 5.9
Standard Deviation, σ = 2.2
We assume that the distribution of response is a bell shaped distribution that is a normal distribution.
Formula:
a) We have to find the value of x such that the probability is 0.92
P(X < x)
Calculation the value from standard normal z table, we have,
A response of 8.9 represents the 92nd percentile.
b) We have to find the value of x such that the probability is 0.62
P(X < x)
Calculation the value from standard normal z table, we have,
A response of 6.6 represents the 62nd percentile.
c) We have to find the value of x such that the probability is 0.25
P(X < x)
Calculation the value from standard normal z table, we have,
A response of 4.4 represents the first quartile.
