Answer:

7.2111(4 decimal places)

Step-by-step explanation:

a squared by b squared=c squared

What is the slope of the line determined by the points (5,-3) and (-9,-6)
Serggg [28]

Answer:

slope = \frac{3}{14}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (5, - 3) and (x₂, y₂ ) = (- 9, - 6)

m = \frac{-6+3}{-9-5} = \frac{-3}{-14} = \frac{3}{14}

A farmer plants the same amount every day, adding up to 1 3/4 acres at the end of the year. If the year is 1/2 over, how many ac
Zepler [3.9K]
Answer:
7/8 Acre

First, convert the mixed number 1 3/4 into an improper fraction. This will be 7/4. Now, divide this by two because the year is half over. Doing this you get 7/8.

Find an equation of the line parallel to −5x+7y=3 that passes through the point (9,−4). If possible, write the equation in slope
saul85 [17]

From the original equation we have:

-5x+7y=37y=5x+3y=\frac{5}{7}x+\frac{3}{7}

The slope of this line is 5/7 and for the new equation to be parallel to the original must have the same slope, and using the point-slope formula we have:

y-(-4)=\frac{5}{7}(x-9)y+4=\frac{5}{7}x-\frac{45}{7}y=\frac{5}{7}x-\frac{45}{7}-4y=\frac{5}{7}x-\frac{73}{7}

A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that a red gumball is drawn if there
fgiga [73]

Answer:

0.99

Step-by-step explanation:

Given,

Pink gumballs = 3,

Red gumballs = 4,

Green gumballs = 2,

So, total gumballs = 3 + 4 + 2 = 9,

Thus, total ways of selecting 5 gumball = ^9C_5

=\frac{9!}{5!4!}

=\frac{9\times 8\times 7\times 6}{24}

=9\times 2\times 7

=126

Also, the total ways of selecting no red gumballs = ^4C_0\times ^5C_5

= 1 × 1

= 1

So, the probability of no red gumballs in 5 drawn

=\frac{1}{126}

Hence, the probability that a red gumball is drawn if there are 5 drawings

= 1 - probability of no red gumballs

=1-\frac{1}{126}

=\frac{125}{126}

≈ 0.99
