Answer:

12:18

Step-by-step explanation:

12*4 = 48 minutes

Answer:

Mike stops running at 12:18 PM

Step-by-step explanation:

We know he runs 1 mile each 12 minutes and we also knows he ran 4 miles so the equation is 12*4 or (12 times 4) which is equal to 48. We then add 38 minutes to 11:30 AM and end up at 12:18 PM.

Answer:

  60°

Step-by-step explanation:

You recognize the ratio of the long side to the short side as 2 : 1, so you know this is the 1 : √3 : 2 "special" triangle that has angles 30°, 60°, 90°. The angle of interest is opposite the longer side, so is the 60° angle.

  x° = 60°

_____

In case you don't remember the "special" 30-60-90 and 45-45-90 right triangles, you can use the relevant trig function:

  Cos = Adjacent/Hypotenuse

  cos(x°) = 16/32 = 1/2

  x° = arccos(1/2)

  x° = 60°

Answer:

0.2

Step-by-step explanation:

A probability is always out of 100% (which also means out of 1)

So the probability that the dice rolls a 1 is 0.15/1, the probability it rolls a 3 is 0.3/1 and the probability it rolls a 4 is 0.35/1. The probability it rolls a 2 is x/1 where x is what we're looking for. If you add all the probabilities up you should have 1 in total. So 0.15 + x + 0.3 + 0.35 = 1

So to find the missing one you need to subtract all the probabilities you know from 1:

1 - 0.15 - 0.3 - 0.35 = 0.2

The probability of the die rolling 2 is 0.2

Probability is a measure of the likelihood of an event occurring. The probability of all the events in a sample space adds up to 1.

Given here the probabilities are 0.15,0.3, 0.35

since the probabilities, all add upto 1

therefore P(2) = 1-(0.15+0.3+0.35)

                       = 0.2

Hence the probability that the die will roll 2 is 0.2

Where's the system? I can't answer your question without it.

Answer:

x would be 6

Step-by-step explanation:

This is becuase since the scale factor from Fig A to B is 0.25, the length of all of the sides follows this rule.

Since x on Fig A and 1.5 on Fig B are corresponding sides, you can do:

x * 0.25 = 1.5

x * 0.25 (4) = 1.5 (4)

x * 1 =6

x = 6

Answer:

  $1,010

Step-by-step explanation:

We can write the exponential decay function in the form ...

  y = a(b^(t/T))

where 'a' is the initial value, and 'b' is the "growth" factor in time period T.

Here, the initial value is 16200, for t=0 corresponding to the year 2010.

The "growth" in value is by the factor 9300/16200 in the 2-year period between 2010 and 2012. This means we can write the exponential function as ...

  y = 16200((93/162)^(t/2))

In the year 2020, the value of t is 2020 -2010 = 10, so the car value will be ...

  y = 16200(93/162)^(10/2) = 16200(93/162)^5 ≈ 1010

The predicted value in 2020 is $1,010.

_____

If you like, you can "simplify" the base of the exponential factor to ...

  (93/162)^(1/2) ≈ 0.75768

Then the value function becomes ...

  y = 16,200(0.75768^t)

Answer:

The number of solutions to the given set of equations is 0.

Step-by-step explanation:

Number of solutions of a system of equations:

System of equations: ax = b

If a = 0 and b = 0, infinite solutions.

If a = 0 and b != 0, zero solutions.

If a != 0 and b != 0, one solution.

We are given the following system of equations:

y = 7x + 12

y = 7x + 2

So

7x + 12 = 7x + 2

7x - 7x = 2 - 12

0x = -10

a = 0, b != 0, so zero solutions.

The number of solutions to the given set of equations is 0.

To find:

The median of the data represented on the box-and-whisker plot.

Solution:

In a box-and-whisker plot of a data set, the line inside the box represents the median of the data set.

In the given box-and-whisker plot, it is clear that the there is a line inside the box at 45. It means the median of the data represented on the box-and-whisker plot is 45.

Therefore, the correct option is C.

Find x and y

From the sign on each line, we have:

[tex]y - 4 = x + 5[/tex]

[tex]2x + 5 = x + 12[/tex]

Collect like terms

[tex]2x-x=12 - 5[/tex]

[tex]x = 7[/tex]

We have: [tex]y - 4 = x + 5[/tex]

Substitute [tex]x = 7[/tex]

[tex]y - 4 = 7+5[/tex]

[tex]y - 4 = 12[/tex]

So:

[tex]y = 12+4[/tex]

Write in mathematical notation

Using mathematical notation,in terms of n.

The given parameters can be rewritten as

[tex]n(0) = a[/tex]

[tex]n(0) = 400[/tex]

and

[tex]\frac{dn}{dt} = r[/tex]

[tex]\frac{dn}{dt} = 40[/tex]

The mathematical notation can be determined using:

[tex]n(t) = n(0) + \frac{dn}{dt} * t[/tex]

So, we have:

[tex]n(t) = 400 + 40 * t[/tex]

[tex]n(t) = 400 + 40 t[/tex]

1.) Subject = 18  Aquariums each with mussel

2.) Factors(levels) = temperature(3 levels) and salinity (2 levels)

3.) Treatment = High salinity high temperature ; High salinity low temperature ; High Salinity medium temperature ; Low salinity Low temperature ; Low salinity, High temperature ; Low salinity Medium temperature.

4.) Response variable = size of mussel produced

5.) Random assignment will help prevent the introduction of bias and confounding variable.

6.) For replication purpose, Each of the six treatment could be assigned to 3 tanks, so 3 aquarium for one treatment.

7.) By doing such we might be a possible location based effect which might might creep into our research. Hence, causing a spurious relationship.

8.) A control experiment whereby no salt is added will cause the mussel to die as they require salt to survive.
