A park in the shape of a right triangle, one leg of the triangle is 2 kilometers long, the hypotenuse measures 2.9 kilometers how long in kilometers is the other leg?

Answers

Answer:

2.1 kilometers

Step-by-step explanation:

Pythagoras' Theorem

a^2 + b^2 = c^2

2^2 + b^2 = 2.9^2

2.9^2 - 2^2 = b^2

8.41 - 4 = 4.41

b = √4.41

b= 2.1

Convert the angle 17pi/12 radians to degrees.

Answers

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°.

can someone help me with this? it’s linear regression and i forgot how to do it

Answers

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.

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.

Answers

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

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

Answers

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%

population increase for the next 20 years was about 6%. Predict the population of Bayside in
2010.

Answers

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
