Answer:
432 in²
Step-by-step explanation:
To Obtian the square inches of wooden boards required :
Area of box = 2(l * w) + 2(l * h) + 2(h * w)
Length = 12 ; width = 6 ; height = 8
Hence,
Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)
Area of box = 2(72) + 2(96) + 2(48)
Area of box = 432 in²

You estimate that there are 60 marbles in a jar.The actual amount is 54 marbles. Find the percent error.Round to the nearest tenth of a percent if necessary
Answer:
the percent error is 10%
Step-by-step explanation:
Given that
The estimate value of the marbles is 60
And, the actual amount is 54 marbles
We need to find out the percent error
As we know that
Percent error = (Estimated - actual) ÷ (Estimated) × 100
= (60 - 54) ÷ 60 × 100
= 10%
Hence, the percent error is 10%
We simply applied the above formula

The area of the base of this cylinder is 25picm^2 and the height of the cylinder is 8cm. Find the surface area of the cylinder.
Answer:
408.2cm
Step-by-step explanation:
Given data
Area of base= 25πcm^2
Height= 8cm
Let us find the radius of the cylinder
Area= πr^2
25π= πr^2
25= r^2
r= √25
r= 5cm
Let us now find the surface area
SA=2πrh+2πr^2
Substitute
SA= 2*3.14*5*8+ 2*3.14*5^2
SA= 251.2+ 157
SA= 408.2cm
Hence the surface area is 408.2cm

can someone help me with this? it’s linear regression and i forgot how to do it
I'll do problem 1 to get you started. The completed filled out table is shown below in the attached image.
We have x as the input and y as the output. The observed value is the second column, and this is the actual y value we're aiming for. The predicted value is an estimation based on what the linear regression line says. The residual is the error or gap between the observed and predicted.
With that in mind, let's fill out the table. In the first row, we have x = 5 pair up with y = 3. The predicted y value is y = 0.5x = 0.5*5 = 2.5, meaning we'll write "2.5" without quotes in the first blank space of that first row. The residual is
e = error or residual
e = (observed y value) - (predicted y value)
e = (3) - (2.5)
e = 0.5
A positive residual means that the observed y value is larger than the predicted one. The predicted y value is an under-estimate. We'll write "0.5" without quotes underneath "residual" in the first row.
-------------------
We'll repeat the same steps for row 2
This time we have x = 10 lead to a predicted y value of y = 0.5*x = 0.5*10 = 5
The residual is
e = (observed) - (predicted) = (4) - (5) = -1
The negative residual tells us the observed value is smaller than the predicted one. The predicted value is an over-estimate.
--------------------
For row 3, we have the input x = 15 lead to a predicted y value of y = 7.5 since y = 0.5*x = 0.5*15 = 7.5
The residual is therefore: e = (observed y) - (predicted y) = (9) - (7.5) = 1.5
The nice thing about how this table is set up, is that the observed y values are listed first, then the predicted y values next. This may help you remember how the order of subtraction will go.
The steps for rows 4 through 6 are the same as mentioned earlier, so there's nothing new here.
The completed table for problem 1 is shown below in the attached image.

Convert the angle 17pi/12 radians to degrees.
Answer: 255°
Step-by-step explanation:
To convert an angle in radians to degree, we've to multiply it by 180/π. In this case, converting the angle 17pi/12 radians to degrees will be:
= 17π/12 × 180/π
= 17 × 15°
= 255°
The answer is 255°.

24. The population of Bayside, CA increased from 23,560 in 1990. The annual rate of
population increase for the next 20 years was about 6%. Predict the population of Bayside in
2010.
Answer:
the population in 2010 is 75,656.33
Step-by-step explanation:
Given that
The increase in population in the year 1990 is 23,560
The Annual rate of interest is 6%
And, the time period is 20 years
We need to find out the population in 2010
So, the following formula should be used
= Population × (1 + rate)^time period
= 23,590 × (1 + 0.06)20
= 23,590 × 1.06^20
= 75,656.33
hence, the population in 2010 is 75,656.33
