Using proportions, it is found that the cost of 6 containers of yogurt is of $3.54.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
4 containers of yogurt cost $2.36, hence the cost of a single container is given by:
2.36/4 = $0.59.
Hence the cost of six containers is given by:
6 x 0.59 = $3.54.

Answer:
$28.50
Step-by-step explanation:
multiply 30 by 5 then divide by 100 and subtract the answer by 30
30×5=150
150÷100=1.5
30-1.5=28.50
Answer:
0.7734; no, it does not.
Step-by-step explanation:
To find this probability we will use a z-score. We are dealing with the probability of a sample mean being larger than a given value; this means we use the formula
Our x-bar in this problem is 155, as that is the sample mean we are trying to find the probability of. Our mean, μ, is 161 and our standard deviation, σ, is 31. Our sample size, n, is 15. This gives us
Using a z table, we see that the area under the curve less than this, corresponding with probability less than this value, is 0.2266. This means that the probability of the sample mean being larger than this is
1-0.2266 = 0.7734, or 77.34%.
Since there is a 77.34% chance of the passengers having a mean weight that is too heavy, this elevator is not safe.
