The temperature outside is dropping at a rate of 1.5 degrees each hour . It last is raining and the weather station predicts a changeover from rain to sleet when the temperature reaches 32*F or below . Currently the temperature is 53*F and the time is 8:30am when do you predict the changeover to sleet will occur?

Answer:

[tex]x = - \frac{3}{5} y + 3[/tex]

Step-by-step explanation:

5x + 3y = 15

5x = 15 - 3 y

x = 3 - (3y/5)

16/3x-4 = 5/x

16x = 5(3x - 4)

16x = 15x - 20

16x - 15x = -20

x = -20

Answer:

-5/4x + 5/2

Step-by-step explanation:

Slope: (-3-2)/5-1) = -5/4

Point: (1,2)

y-2 = -5/4 (x -1)

y - 2 = -5/4x +5/4

y = -5/4x + 5/4 + 2

y = -5/4x + 13/4

Answer:

To convert the measurements of metric system into another units of metric system we have to either multiply it by 10, 100, 1000, 10000, 100000, etc or divide by 10, 100, 1000, 10000, 100000, etc.

If we have to convert bigger unit into smaller unit then we have to multiply the unit by the multiples of 10, then the decimal point is shifted to right by 1 or 2 or 3 or 4 , etc. places.

For example, 1.2 kg is converted into g so we have to multiply it by 1000, so decimal point is shifted to right by 3 places, i.e.,

1.2 x 1000 = 1200 g

If we have to convert smaller unit into bigger unit then we have to divide the unit by the multiples of 10, then the decimal point is shifted to left by 1 or 2 or 3 or 4 , etc. places.

For example, 12 cm is converted into m so we have to divide it by 100, so decimal point is shifted to left by 2 places, i.e.,

12 / 100 = 0.12 m

Step-by-step explanation:

Statisticians use two-way tables and segmented bar charts to examine the relationship between two categorical variables.

Answer:

6,4,2,10,18,15,35,10,15,5

We know that for a given set of N elements:

{x₁, x₂, ..., xₙ}

The mean is given by:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

And the standard deviation is given by:

[tex]S = \sqrt{\frac{\sum (x_i - M)^2}{N - 1} }[/tex]

With this, we will find that our set is: {12, 12, 12, 12, 12, 12, 12, 12, 12, 12}

To get this we need to see the information given:

The set has 10 elements.

The mean of the set is 12

The standard deviation is 0.

This last one is really important, you can see that if we have at least one element different than the mean, then we will have at least one term different than zero in the standard deviation sum. Thus, the standard deviation can only be zero if all the elements of the set are the same element (thus, all the elements are equal to the mean).

Then the set is:

{12, 12, 12, 12, 12, 12, 12, 12, 12, 12}

Answer:

AC intersect with DR at A

i dont know i wish I could help.

Answer:

-2 to 2

Step-by-step explanation:

see there's the sign of absolute value around x

so even if we put a negative number in place of x we'll get a positive outcome.

for example,

|x| = 4

|x| = 3

and so on

so the actual domain of |x| reduces to => 0 to 4.

as you'll get the values of |x| in between 0 and 4 throughout -4 to 4.

where the smallest value is 0 and largest is 4.

for range,

I'll just put these smallest and largest values in place of x and solve for domain

y= |0| - 2

y = -2

y = |4| - 2

y= 4 - 2

y = 2

so, the range of the function becomes -2 to 2.
