The machine can make 48 parts in 24.8 hours because if you times 4.8 times 5 you will get 24 but you need 24.8 so you would have to go up one more number which will be 6. After that you will need to times 6 and 8 to get the numbers of parts which is 48 but you can also count up 2 because 1 hr the machine can make 2 parts.

Alinara [238K]

Answer:

x = 7/2 y = 5/2

Step-by-step explanation:

You can either use the elimiation or adding and subtracting method to get the variables for both x & y.

Once you solved for one variable, plug in the variable you just solved back into the original equation to find the other variable.

Students in a statistics class are conducting a survey to estimate the mean number of units students at their college are enroll
Papessa [141]

Answer:

The 95% confidence interval for the average number of units that students in their college are enrolled in is between 11.7 and 12.5 units.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 45 - 1 = 44

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 44 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975. So we have T = 2

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2\frac{1.5}{\sqrt{45}} = 0.4

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 12.1 - 0.4 = 11.7 units

The upper end of the interval is the sample mean added to M. So it is 12.1 + 0.4 = 12.5 units

The 95% confidence interval for the average number of units that students in their college are enrolled in is between 11.7 and 12.5 units.

The sum of three consecutive numbers is 123. what is the smallest of the three numbers
bixtya [17]

Answer:

Smallest of the three = 40

Step-by-step explanation:

Consecutive means: x+x+1+x+2 = 123 set X as the smallest number.

x+x+x+1+2=123

3x+3=123

3x= 120

x=40

What are two equivalent forms for the polynomial 3x - 2x -2x? How do you get them?
Lynna [10]
Simplify 3x -2x -2x = 3x + -2x + -2x  
Combine like terms: 3x + -2x + -2x = (3x + -2x +-2x) = -x 
answer is: -x

An angle measures 14° less than the measure of its complementary angle. What is the measure of each angle?
zmey [24]
(180-14):2= 166:2= 83° (smaller angle)
(180-14):2+14= 166:2+14= 83+14= 97° (bigger angle)
