Answer: 30 minutes

Step-by-step explanation:

1/10 miles = 1 minute

3 miles = x

1/10x = 3

Multiply both sides by 10

x = 30

Isa would run 3 miles in 30 minutes.

Hope this helped!

Answer:

order is

αb<αc<αa

Step-by-step explanation:

in a )

number 4 and number 12 are showing 3 bullets while number 7 and 9 showing 2 bullets hence

standard deviation for a=3-2=1

in b)

number 4 ,7,9 and number 12 are showing 2 bullets while number 3 and 13 showing 1 bullet hence

standard deviation for a=2-1=1

in c)

number 4 ,7,9 and number 12 are showing 2 bullets while number 5 and 11 showing 1 bullet hence

standard deviation for a=2-1=1

order isαb<αc<αa

Answer: $\huge\boxed{\boxed{15}}$

Step-by-step explanation:

Given expression

$\large\boxed{\frac{12[30 - (9+4^2)]}{|10|-|-6| } }$

Simplify the exponents

$\large\boxed{=\frac{12[30 - (9+16)]}{|10|-|-6| } }$

Simplify values in the parenthesis

$\large\boxed{=\frac{12[30 - 25]}{|10|-|-6| } }$

$\large\boxed{=\frac{12[5]}{|10|-|-6| } }$

Simplify absolute values (all positive)

$\large\boxed{=\frac{12[5]}{10-6 } }$

$\large\boxed{=\frac{12[5]}{4 } }$

Simplify by division

$\large\boxed{=3~[5]}$

Simplify by multiplication

$\huge\boxed{\boxed{=15}}$

Hope this helps!! :)

X values:−10,−3-, 4, 11

Alex Ar [27]

Answer:

It is neither linear nor exponential.

Step-by-step explanation:

x values: −10,−3, 4, 11

y values: 1, 6, 30, 120

Slope = rate of change

$m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{6-1}{-3+10}\\m=\frac{5}{7}$

$\\m = \frac{y_3-y_2}{x_3-x_2}\\m = \frac{30-6}{4+3}\\m=\frac{24}{7}$

Since rate of change is not constant . So, It is not linear

If the average rate of change is constant, then the function is linear.

If the ratio of consecutive outputs is constant, then the function is exponential.

So, $\frac{y_2}{y_1}=\frac{6}{1}=5\\\frac{y_3}{y_2}=\frac{30}{6}=6\\\frac{y_4}{y_3}=\frac{120}{30}=4$

Since the ratio of consecutive outputs is not constant.

So, It is not exponential

Hence it is neither linear nor exponential.

Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions. The reason for that is that the two equations would be "dependent."

On the other hand, looking at the system

-2x+ 3y= 18
-2x+ 3y= 19

we see that there is no solution. Why? Because -2x + 3y cannot equal 18 and 19 at the same time. You'd have two non-intersecting, parallel lines.
