A software company is hiring some programmers to add to its development team. A junior programmer salary is $48,000 and a senior
1 answer:
Answer:
Step-by-step explanation:
x is the number of junior programmers.
Each junior programmers costs $48,000.
So, the cost of x junior programmers is
48,000x
y is the number of senior programmers
Each senior programmer costs $86,000
So the cost of y seniors programmers is
86,000y
The total cost for x junior programmers and y seniors programmers is
48,000x + 86,000y
To keep costs down, the total spending on these new positions must be under $1,200,000 annually.
So the inequality is:

Answer:
The probability of the stick's weight being 2.33 oz or greater is 0.0041 or 0.41%.
Step-by-step explanation:
Given:
Weight of a given sample (x) = 2.33 oz
Mean weight (μ) = 1.75 oz
Standard deviation (σ) = 0.22 oz
The distribution is normal distribution.
So, first, we will find the z-score of the distribution using the formula:
Plug in the values and solve for 'z'. This gives,
So, the z-score of the distribution is 2.64.
Now, we need the probability .
From the normal distribution table for z-score equal to 2.64, the value of the probability is 0.9959. This is the area to the left of the curve or less than z-score value.
But, we need area more than the z-score value. So, the area is:
Therefore, the probability of the stick's weight being 2.33 oz or greater is 0.0041 or 0.41%.
