Answer:

a slope is that

Step-by-step explanation:

arrow a slope the diangnle one

Answer:

5

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

         = (7 - 2) / (4 - 3)

         = 5 / 1

         = 5

The slope of the line passing through the points (3 2) and (4 7) is 5

The formula for calculating the slope of a line passing through the point (3 2) and (4 7) is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{7-2}{4-3}\\m=\frac{5}{1} \\m=5[/tex]

Hence the slope of the line passing through the points (3 2) and (4 7) is 5

Answer:

4 weeks

Step-by-step explanation:

1 1/6 every week x 4weeks = 4 1/6

Answer:

About 4 weeks

Step-by-step explanation:

x = 1 1/6w

4 1/6 = 1 1/6w

25/6 = 7/6w

6/7 x 25/6 = 7/6w x  6/7

150/42 = w

3.57142857143 = w

w ≈ 4

The correct option is a

Step-by-step explanation:

From the question we are told that

   The population mean is  [tex]\mu = 30\ seconds[/tex]

    The standard deviation is  [tex]\sigma = 3 \ seconds[/tex]

     The sample size is  n  = 9

    The null hypothesis is [tex]H_o: \mu = 30[/tex]

     The alternative hypothesis is  [tex]H_a : \mu \ne 30[/tex]

    The level of significance is  [tex]\alpha = 0.01[/tex]

    The sample mean is  [tex]\= x = 31.2[/tex]

Generally the test statistics is mathematically represented as

      [tex]z = \frac{ \= x - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]

=>   [tex]z = \frac{ 31.2 - 30}{ \frac{3}{\sqrt{9} } }[/tex]

=>   [tex]z = 1.2[/tex]

From the z table  the area under the normal curve to the right corresponding to  1.2  is    

         [tex]P(Z > 1.2) = 0.11507[/tex]

Generally the p-value is mathematically represented as

         [tex]p-value = 2 * P(Z > 1.2)[/tex]

=>       [tex]p-value = 2 *0.11507[/tex]

=>       [tex]p-value = 0.230[/tex]

From the value obtained w can see that

         [tex]p-value > \alpha[/tex] hence

The decision rule is  

Fail to reject the null hypothesis

Answer:

a)

Growth rate 0.075

Growth factor 1.075

b) 59177 or approx 60000

Step-by-step explanation:

I love these kind of question where we get to model equations :D So lets get started.

a)

The population of a city after t years after 2010 is given by

[tex]P=20000(1.075)^t[/tex]

The original exponential growth formula is:

[tex]y=a(1+r)^t[/tex]

so we can write our equation in this form as well:

[tex]P=20000(1+0.075)^t[/tex]

the growth factor is 1+r which is 1+0.075 which is 1.075

the growth rate is determined by the value of r which is 0.075

b)

Since our equation represents the population of a city after the year 2010 we can use it to further calculate the population in 2025 so

2025 - 2010 = 15

we set the value of t in our equation to 15 which is in years,

[tex]P=20000(1.075)^{15}\\P=59177[/tex]

so we can say that our population in 2025 would be approximately 60,000

Answer:

the answer is 5

Step-by-step explanation:

*additive inverse of a number is the number that when added to its original number yields to zero. the number is also known as the opposite or negation

let the additive inverse be = x

-5 + x = 0

x = 0 + 5

x = 5

the additive inverse of -5 is 5

Answer:

The rate of the current is 5.5 miles per hour

Step-by-step explanation:

Relative Speeds

The boat takes 2 hours to travel 15 miles upriver against the current. The speed is 15/2 = 7.5 miles per hour.

Since the boat in still water can travel at 13 miles per hour, it means the current subtracts its speed from the speed of the boat:

Vcurrent = 13 mi/h - 7.5 mi/h

Vcurrent = 5.5 mi/h

The rate of the current is 5.5 miles per hour

it is -16 because I took the test

Answer:

(2,9) (4,9) (6,10) (8,11)

Step-by-step explanation:

X is the input. Y is the output. In an ordered pair (X, Y) we must match the inputs and outputs based off the arrows. We see that the 2 in the input section points to the 9. This signifies an ordered pair. From this, we can graph these points.

Answer:

Since it is multiplied by ten, its basically multiplying 8.88 by 1 and moving the decimal to the right once. Multiplying numbers by 10s, 100s etc. means you have to shift the decimal point to the right based on a number of zeros multiplied.
