Step-by-step explanation:
<u><em>The complete question is</em></u>
Tasha ordered soup and salad for lunch. The soup cost 15 cents per ounce, and the salad cost 20 cents per ounce. If Tasha ordered 10 ounces of soup for lunch and the total cost was $3.30, how many ounces of salad did
Tasha order?
Let
x -----> the ounces of soup ordered
y -----> the ounces of salad ordered
we know that
The ounces of soup ordered multiplied by their cost plus the ounces of salad ordered multiplied by their cost must be equal to $3.30
so
-----> equation A
substitute the value of x in the equation A and solve for y
Subtract 1.50 both sides
Divide by 0.20 both sides
therefore
Tasha ordered 9 ounces of salad

Answer:
Individuals with calcium level 8.7 mg/dL or low are considered with low calcium level and above that are not considered low.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 9.5 mg/dL
Standard Deviation, σ = 0.5 mg/dL
We are given that the distribution of calcium levels is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.05
Calculation the value from standard normal z table, we have,
Thus, individuals with calcium level 8.7 mg/dL or low are considered with low calcium level and above that are not considered low.
