Answer:

I believe it is y=2x+6.

Answer:

[tex]y=2\,x+6[/tex]

Step-by-step explanation:

Start by finding the slope of the segment that joins the two given points, using the slope formula:

[tex]slope=\frac{y_2-y_1}{x_2-x_1} =\frac{12-(-4)}{3-(-5)} =\frac{16}{8} =2[/tex]

Now, you can write the general equation of the line in slope-intercept form as:

[tex]y=m\,x+b\\y=2\,x+b[/tex]

and find the line's y-intercept (b) by using either one of the given points - for example (3, 12):

[tex]y=2\,x+b\\12=2\,(3)+b\\12=6+b\\b=6[/tex]

Therefore, the equation of the line is:

[tex]y=2\,x+6[/tex]

Answer:

0.5%/year

24.2%

Step-by-step explanation:

Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation

Percentage of females by year:

1980 = 6.2%

1990 = 10.8%

2000 = 13.6%

2012 = 21.7%

Average yearly increase :

Percentage increase between 1980 - 2012 :

2012% - 1980% = ( 21.7% - 6.2%) = 15.5% increase over [(2012 - 1980)] = 32 years

15.5 % / 32 years = 0.484375% / year = 0.5%/year

b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,

Given an average increase of 0.484375% / year

(2030 - 1980) = 50 years

Hence by 2030 ; ( 50 years × 0.484375%/year) = 24.218% will claim no religious affiliation.

=24.2% (nearest tenth)

In this exercise we have to use the percentage knowledge to calculate an estimate per year, in this way we find that;

A) [tex]0.5\%/year[/tex]

B) [tex]24.2\%[/tex]

Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation.  Percentage of females by year:

[tex]1980 = 6.2\%\\1990 = 10.8\%\\2000 = 13.6\%\\2012 = 21.7\%[/tex]

A) Average yearly increase  can be caculeted by:

[tex]2012\% - 1980\% = ( 21.7\% - 6.2\%) = 15.5\% = 32 years \\15.5 \% / 32 years = 0.484375\% / year = 0.5\%/year\\[/tex]

B)  Estimate the portion of first-old age institution of higher education woman the one will claim no religious association with an organization fashionable 2030, Given an average increase of:

[tex](2030 - 1980) = 50 years\\ ( 50 years * 0.484375\%/year) = 24.2\%[/tex]

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

No of tulips = 60

No of daffodils = 72

We need to find the greatest number of bouquets the florist can make if the florist will make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.

It would mean that we need to find the HCF of 60 and 72

Prime factorisation of 60 = 2×2×3×5

Prime factorization of 72 =  2 x 2 x 2 x 3 x 3

Highest common factor or HCF = 2×2×3 = 12

So, the florist can make 12 bouquets as maximum number.

Answer:

Ashley can serve 12 pieces of pizza in the party

Step-by-step explanation:

To solve this question we need to convert the 9 pizzas to decimal:

9 times 4 = 36. That is:

9 pizzas are equal to 36/4 of pizza (36/4 = 9)

As Ashley is serving 3/4 of a pizza she can serve:

36/4 ÷ 3/4 = 36/3 = 12

Answer:

ROS=72° TOS=83°

Step-by-step explanation:

(4x-20)+(3x+14)=155

7x-6=155

7x=161

x=23

4(23)-20=72

3(23)+14=83

Answer:

ROS is 72 degrees.

TOS is 83 degrees.

Step-by-step explanation:

So we know that the measure of Angle ROT is 155.

Angle ROT is the combined value of Angle ROS and Angle TOS. In other words:

[tex]ROT=ROS+TOS[/tex]

Substitute 155 for ROT, (4x-20) for ROS, and (3x+14) for TOS. Thus:

[tex]155=(4x-20)+(3x+14)[/tex]

Combine like terms:

[tex]155=(4x+3x)+(-20+14)[/tex]

Add:

[tex]155=7x-6[/tex]

Add 6 to both sides:

[tex]161=7x[/tex]

Divide both sides by 7:

[tex]x=23[/tex]

So, the value of x is 23.

Now, plug that into each of the Angle equations to solve for each angle:

[tex]ROS=4x-20\\ROS=4(23)-20[/tex]

Multiply:

[tex]ROS=92-20[/tex]

Subtract:

[tex]ROS=72[/tex]

Same thing for TOS:

[tex]TOS=3x+14\\TOS=3(23)+14[/tex]

Multiply:

[tex]TOS=69+14[/tex]

Add:

[tex]TOS=83[/tex]

And we're done!

Answer: D

Step-by-step explanation:

The pair of variables that will most likely have a negative correlation are D. the time spent reading a book and the number of pages remaining to be read in the book.

If you spend a longer time reading a book, you would read more pages which would reduce the number of pages left to be read. The time taken to read the book is therefore negatively correlated with the number of pages left.

In conclusion, option D is correct.

Answer: 0.3

Step-by-step explanation:

A percent that is equivalent to 3/10 is: D.) 30%.

In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.

By multiplying both the numerator and denominator by a common number such as 10, we have the following:

3/10 × 10/10

30/100

30%

Based on the information provided, we can logically deduce that 30% is equivalent to 3/10. Therefore, the correct answer option is: D.) 30%.

Step-by-step explanation:

Answer: inductive argument.

Step-by-step explanation:

Deductive argument is a logical argument in which a conclusion is made upon the given premises which are assumed to be true.

inductive argument works on the basis of a series of observation and then bring it to frame a certain conclusion.

Here, Flanagans are considering the observation they made by previous children (i.e. they are athletically gifted) and applying the same on the new one by saying "youngest child is bound to be athletically gifted as well.".

So it is of-course an inductive argument.

Answer:

Step-by-step explanation:

y = kx² - 3x

Since the points lie on the graph we can substitute the values of x and y that's

( 2 ,6) into the equation to find k.

We have

6 = (2)²k - 3(2)

6 = 4k - 6

4k = 6 + 6

4k = 12

Divide both sides by k

That's
