Answer:

1st or each day=314km

Let x in km be the total km for 10 days

10=x

>314×10=x

X=3140km

Therefore, for 10days, the road constructed was 3140km

-5+ 3= 2) -7 -4 3) 122 × (-9) 4) -6 divided by 3/4
lutik1710 [3]

Answer:

Step-by-step explanation:

1) -5 +3 = -2

When two numbers are in different sign, subtract and the result will have the bigger numbers sign.  The bigger number is 5. so the result is (-2)

2) -7 - 2 = -9

When two numbers have same sign, add and the result will have the common sign

3) 122 * (-9) = - 1098

4) -6 ÷ (3/4)

=(-6)*\frac{4}{3}\\\\=-2*4

= -8

Use a graphing calculator to find the value of the correlation coefficient r to determine if there is a strong correlation among
OlgaM077 [116]

The value for r = - 0.8535 ,  there is strong correlation between the variables.

<h3>What is a correlation coefficient  ?</h3>

Correlation coefficient describes the relationship between the two variables in the data .

The data given is

(1, 7), (2, 5), (3, -1), (4, 3), (5, -5)

Assuming Linear Regression ,

The data is plotted on the graphing calculator

The value for r = - 0.8535

as the value is in the range of - .85 to -1 , therefore there is strong correlation between the variables.

In the year 2005, a total of 750 fish were introduced into a man made lake. The fish population was expected to grow at a rate o
Butoxors [25]

Answer:

In 2050 fish population is 27000

Step-by-step explanation:

Exponential change can be modeled by,

F=F(0)+x^{n}

Where F(0) is the initial value of 750, x is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and n is the number of time periods.

The rate of change in percentage is 8.3%

That means, after 1 year fish will become 108.3 for 100 fish.

Then x=\frac{108.3}{100}

x=1.083

Difference of years is, n=2050-2005=45

Then, F=750+1.083^{45}

F=27000

So, the fish population in 2050 is 27000
