The deer population is estimated to be 17,600 in northern
Illinois, but an actual count was 21,300. What is the percent
error?

Answers

The percentage error in the deer population is 17%

Actual population = 21300

Estimated population = 17600

The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:

= (Actual population - Estimated population) / Actual population × 100

= (21300 - 17600) / 21300 × 100

= 3700/21300 × 100

= 0.17 × 100

= 17%

Therefore, the percentage error in the deer population is 17%

Since the pint is reflected over the y-axis, its y-coordinate remains the same.

Point (4, 5) has 4 as its x-coordinate. That is 4 units right of the y-axis. The reflection has -4 as its x-coordinate which is 4 units left of the y-axis.

Answer:

1, 3, 5

Step-by-step explanation:

let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then

5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )

5n + 10 = 2(2n + 4) + 3

5n + 10 = 4n + 8 + 3

5n + 10 = 4n + 11 ( subtract 4n from both sides )

n + 10 = 11 ( subtract 10 from both sides )

n = 1

n + 2 = 1 + 2 = 3

n + 4 = 1 + 4 = 5

The 3 consecutive odd numbers are 1, 3, 5

Step-by-step explanation:

let the three consecutive odd number be x + 1 , x + 3 , x + 5

a/q

5 times the middle number = 5(x + 3) is

3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )

so,

= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )

= 5x + 15 = 3 + 4x + 12

= 5x + 15 = 4x + 15

= -4x + 5x = 15 - 15 = 0

= x = 0

so, the 3 consecutive odd numbers are,

x + 1 = 1

x + 3 = 3

x + 5 = 5

and also a/q

5 times the middle number = 5×3 = 15

is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15

LHS = RHS

What is a clock?

A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.

Now,

Time in    Time out

 7:05          2:58

 7:30          5:01

 8:01          4:32

 7:22          4:46

 6:55          3:31

Between 7:05 and 2:58 the number of hours is 7 hours 53 minutes

Between 7:30 and 5:01 the number of hours is 9 hours 31 minutes

Between 8:01 and 4:32 the number of hours is 8 hours 31 minutes

Between 7:22 and 4:46 the number of hours is 9 hours 24 minutes

Between 6:55 and 3:31 the number of hours is 8 hours 36 minutes

Now, (7+9+8+8+8)+(53+31+31+24+36)

= 40 hours + 175 minutes

= 40 hours + 2 hours 55 minutes

= 43 hours 55 minutes

= 44 hours

Therefore, the number of hours Janice worked in a week is 44 hours.

Simplify ^75 select the correct answer

Answers

Answer:

to simplify the square root of 75, first I recognize that the perfect square 25 goes into it. So 75 = 25 x 3. Therefore the square root of 75 equals the square root of 25 times the square root of 3. And that means just 5 times the square root of 3.

Step-by-step explanation:

The square root of √75 is 5√3.

What is Radical?

The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.

A radical notation is an expression that incorporates a root, such as the square or cube root.

Given:

We have to find the square root of 75.

So, we have to factories 75 as

= 25 x 3

and, the square root of 25 is 5.

Then, √75 = √( 5 x 5 x 3)

Answers

g(x)=1/5x² is the equation for blue graph.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The equation of the red quadratic graph is f(x)=x²

This is the parent quadratic function or the base of the quadratic functions.

This red quadratic graph has been dilated by a certain scale factor  to obtain the blue graph.

Recall that, when the scale factor is a fraction, such that 0<k<1 the graph is stretched horizontally.

The dilated graph then becomes wider than the parent function.

From the given function equations, the possible value of k can only be k=1/5

Therefore the blue graph has equation g(x)=1/5x²

Hence, g(x)=1/5x² is the equation for blue graph.
