Answer:

The slope of the line is -18

Step-by-step explanation:

$\textbf{Use Slope Formula:}$ $m=\frac{y_2-y_2}{x_2-x_1}$

m= slope

$\textbf{points}: (34, 12)\:and\: (32, 48).$

Plugin the points into the formula:

$m=\frac{48-12}{32-34}$

Subtract 48-12=36:

$m=\frac{36}{32-34}$

Subtract 32-34=-2

$m=\frac{36}{-2}$

Apply fraction rule: $\frac{a}{-b}=-\frac{a}{b}$

$m=-\frac{36}{2}$

Divide 36 ÷ 2 = 18

$m=-18$

Point (34, 12)

Point (32, 48)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{48 - 12}{32 - 34}$
Simplify: $\displaystyle m = -18$

How do you do factoring the gcf out of a binomial

iVinArrow [24]

In general: look for what the terms have in common. for example, take the binomial 2x² - 4x. you would be able to factor out a "2" because of the coefficients, and both terms have an "x" -- you can take that out too. that makes your GCF 2x. technically, what you're doing with factoring is dividing the terms by your GCF--2x² divided by 2x leaves you with x, and 4x divided by 2x leaves you with two. that's how you end up with (x - 2) in your binomial. your result looks like this: 2x(x - 2).

if you have any specific binomials you need help with, feel free to send me a message or comment on this and i'll see if i can help. if you're just asking in general, then just remember to look for what the terms have in common, then take it out.

A Department of Transportation report about air travel found that nationwide, 76% of all flights are on time. Base the following

ser-zykov [4K]

Answer:

30 flights are expected to be late.

Step-by-step explanation:

Consider the provided information.

A Department of Transportation report about air travel found that nationwide, 76% of all flights are on time.

That means 100-76% = 24% of all flights are not on time.

125 randomly selected flights.

We need to find flights would you expect to be late.

Flight expect to be late E(x) = nq

Here n is 125 and the probability of late is 24 or q = 0.24

Thus substitute the respective values in the above formula.

Flight expect to be late E(x) = 125 × 0.24 = 30

Hence, the 30 flights are expected to be late.

Answer:

$Quadrant\ IV = (5, -3)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Step-by-step explanation:

Given

$Quadrant\ IV = (5, -3)$

$Quadrant\ II = (-4, -8)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Required

Determine which coordinate fall in the right quadrant

First, we split the each quadrant into x and y axis

In the first:

x and y is +

In the second:

x is - and y is +

In the third

x and y are -

In the fourth

x is + and y is -

Comparing the given coordinates to their respective quadrants, base on the conditions stated above

$Quadrant\ IV = (5, -3)$ is correct

$Quadrant\ I = (9, 11)$ is correct

$Quadrant\ II = (-1, 3)$ is correct

$Quadrant\ III = (-2, -4)$ is correct

$Quadrant\ II = (-4, -8)$ is incorrect

Help me solve this please

drek231 [11]

Answer:

x is 46.67

y is 28.4°

Step-by-step explanation:

To solve for x we use sine

sin ∅ = opposite / hypotenuse

AC is the opposite

x is the hypotenuse

so we have

sin 59° = 40 / x

x sin 59 = 40

Divide both sides by sin 59

x = 40/sin 59

x = 46.67

To solve for y we also use sine

sin y = 30/ 63

y = sin^-1(30/63)

y = 28.4°

Hope this helps you
