Options:
The answer is the third option "10; it represents the hourly wage for the worker." 10 would be the slope and if x represents hours then 10 would represent the amount of money the worker would get every hour.
Hope this helps!
Answer:
10
Step-by-step explanation:
Given that the local ice cream shop is deciding whether or not to hire a new worker. The shop must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y=10x+30 where x=hours.
We find that this is of the form y = mx+B where
m=10 and B =30
Hence slope =m =10
Answer is 10
and it represents the rate of change of y for a unit change in x.
Assume the population standard deviation is the same. What is the 98% confidence interval for the mean hours devoted to social networking in January?
2)Two studies were completed in Florida. One study in northern Florida involved 2,000 patients; 64% of them experienced flu-like symptoms during the month of December.
The other study, in southern Florida, involved 3,000 patients;
54% of them experienced flu-like symptoms during the same month. Which study has the smallest margin of error for a 95% confidence interval?
The positive x-intercept is at (___,0)
we know that
The x-intercept is the value of x when the value of the function is equal to zero.
in this problem we have
To find the x-intercepts equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
square root both sides
therefore
the answer is
The negative x-intercept is at
The positive x-intercept is at
The negative x-intercept is (-1/3, 0) and the positive x-intercept is (4,0)
Given the expression 3x²-11x-4, the x intercept occur that the point where f(x) = 0.
The function will become 3x²-11x-4 = 0
Factorize the result to have:
Group the function to have;
Factor out the GCF
3x(x-4) + 1(x-4) = 0
(3x+1) (x-4) = 0
Get the x-intercepts
3x+1 = 0
x = -1/3
Hence the negative x-intercept is (-1/3, 0)
Also, x-4 = 0
x = 4
Hence the positive x-intercept is (4, 0)

Answer:
32
Step-by-step explanation:
Let there be n number of steps on the ladder.
First, the firefighter climbed up to the middle of a ladder. so to reach the middle of the ladder he must have climbed steps.
Then, after climbed 10 more steps, the total number of stairs from the ground he climbed .
Then, he came back down 14 steps, so the total number of stairs from the ground he climbed .
Remaining steps
Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,
Hence, there are 32 steps on the ladder.
unit rate
