Answer:

y=3x+2

Step-by-step explanation:

First find the slope or m in the line of equation y=mx+b

to find slope you need two points, plug in to y2-y1 / x2-x1

so lets use points (0,2) (1,5)

5-2 / 1-0 = 3

m=3

we have y=3x + b

now we find b by pugging in a point, let's use (0,2)

2 = 3(0) + b

b= 2

y=3x+2

Answer:

Second test

Step-by-step explanation:

Given that :

FIRST TEST

Mean (m) = 325

Standard deviation (s) = 100

Score (x) = 425

SECOND TEST

Mean (m) = 50

Standard deviation (s) = 6

Score (x) = 65

Express both scores as standardized scores:

Zscore = (x - m) / s

First Score :

Zscore = (425 - 325) / 100

Zscore = 100/100 = 1

SECOND SCORE :

Zscore = (65 - 50) / 6

Zscore = 15 / 6 = 2.5

Student performed better on second test :

Zscore second > Zscore first

Answer:

40%

Step-by-step explanation:

First, find how many of the first 200 were in color:

200(0.2)

= 40

Then, find how many of the next 300 were in color:

300(0.4)

= 120

Find how many of the last 100 were in color:

100(0.8)

= 80

Then, add these all together to find how many were in color:

40 + 120 + 80

= 240

Then, divide 240 by 600 to find the percent that were in color:

240/600

= 0.4

So, 40% of the 600 advertisements were in color

Answer:

simplified it is 75 the square root of 75 is 8.66025403784

Step-by-step explanation:

5% of $80 is $4.

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.

Given that, ____% of $80 = $4

Let x be the percent,

x% of 80 = 4

x = 4*100/80 = 5

Hence, 5% of $80 is $4.

Answer:

The general rule for the nth term of this sequence will be:

[tex]a_n=3na+9a[/tex]

Step-by-step explanation:

Given the sequence

12a, 15a, 18a, 21a, 24a,...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Here,

a₁ = 12a

computing the differences of all the adjacent terms

d = 15a-12a = 3a, d = 18a-15a=3a, d=21a-18a=3a, d=24a-21a=3a

using the nth term formula

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting a₁ = 12a, d = 3a

[tex]a_n=12a+\left(n-1\right)3a[/tex]

     [tex]=12a+3na-3a[/tex]

     [tex]=3na+9a[/tex]

Therefore, the general rule for the nth term of this sequence will be:

[tex]a_n=3na+9a[/tex]

Answe - 0. 5692

Step-by-step explanation:

the step is only to let 1 be 10000 and then subtract 4308 from 10000 and it u have any confusion then u can also check it by adding the answer with 4308

and that's it.

If u think it's helpful then plz share to ur friends too.

The difference is 0.5692.

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Here we have to find the difference of 1 - 0.4308.

Here, the number is 0.4308, which is a decimal number.

Write 1 as the decimal number as 1.0000

Subtracting as done as usual whole numbers, we get,

1.0000 - 0.4308 = 0.5692

Hence the difference of the given numbers is 0.5692.

Answer:

Step-by-step explanation:

Just took the test on iready it was right.

The number of collections of 7 books can you​ take is 1685.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Total books= 15

n = 15 (the number of possible books) and r = 7 (the number of books to be taken).

Now,

To find the number of different collections of 7 books, we can use the formula for combinations. Combinations are ways of selecting items from a collection, such that the order of selection does not matter.

The formula for combinations is:

nCr = n! / (r! (n - r)!)

where n is the number of items in the collection, r is the number of items to be selected, and ! is the factorial operator.

We can plug these values into the formula:

15C7 = 15! / (7! (15 - 7)!)

= 15! / (7! 8!)

= (15 x 14 x 13 x 12 x 11 x 10 x 9 x 8!) / (7! 8!)

= (15 x 14 x 13 x 12 x 11 x 10 x 9) / (7 x 6 x 5 x 4 x 3 x 2 x 1)

= (6435 x 1320) / (5040)

= 8491770 / 5040

= 1685.25

Since we cannot have a fraction of a collection, we round down to get the final answer:

15C7 = 1685

Therefor, by algebra the answer will be 1685.
