Which equation reprints the slope intercept form of the line below ? Y- intercept = (0,2) slope = -3/7

Mathematics

Ann [662]3 years ago

Answer:

y = -\frac{3}{7} x + 2

Step-by-step explanation:

The y-intercept of the line is (0,2)

The slope of the line is  -\frac{3}{7}

We derive the slope of a line by dividing the change in y by the change in x

So,

\frac{y - 2}{x - 0} =  -\frac{3}{7}

y - 2 =  -\frac{3}{7} x

The equation of the line therefore is;

y =  -\frac{3}{7} x + 2

Let's say "m" is the manufactoring cost per drill (in dollars).

Then the manufactorer sells it for $4 more, so this would be:

    m+4

Then the chain store sells it for 140% of the price is paid the manufactorer, so this would be "140% of (m+4)" which translates to "1.4•(m+4)" or more simply:

    1.4(m+4)

P(m) = 1.4(m+4), where m is the initial manufactoring cost (in dollars).

Simplifying, you could rewrite this as:

     P(m) = 1.4m + 5.6

Of the 75% of a group that passed a physical examination only 3/5 passed the additional psychological exam. What fraction of the
Helga [31]
To find the fraction of the grouo that passed both exams, we need to first convert 75% into a fraction:

75%
=75/100
=3/4

We can then mutiply the fraction above by the students who passed the psychological exam:

3/4×3/5
=9/20

Therefore the answer is 9/20.

Hope it helps!

An experiment consists of rolling two fair number cubes. What is the probability that the sum of the two numbers will be >3
liraira [26]

Answer:   \bold{\dfrac{5}{12}}

<u>Step-by-step explanation:</u>

greater than 3 means the sum is either 4, 5, or 6.

There are 15 permutations that meet the criteria:

(1, 3), (1, 4), (1, 5), (1,6)

(2, 2), (2, 3), (2, 4), (2, 5), (2,6)

(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3,6)

(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4,6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5,6)

(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6,6)

There are 6²= 36 total permutations for 2 dice.

Probability=\dfrac{\#\ of\ permutations> 3}{total\ \#\ of\ permutations}\\\\.\qquad \qquad =\dfrac{15}{36}\\\\.\qquad \qquad =\dfrac{5}{12}\\\\

=>cot36°= 1/0.726543

=>so cot 36°= 1.376382

So correct answer is option D.
