Answer:

Step-by-step explanation:

To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.

Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.

$\frac{10}{16} = \frac{5}{8}$

As we cannot simplify 5/8 any further, this is the final answer.

Find the area of quadrilateral ABCD in each case.<br> HElp PLEase ASAP

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

Let's see...

Step-by-step explanation:

*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.

<h3>The coordinates of the bigger figure:</h3>

A = (0,0)

B' = (0,4)

C = (5,4)

D' = (5,0)

Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.

<h3>That being said, what is the area of the bigger figure?</h3>

A = l * w

A = 4 * 5

A = 20 units²

<h3>Now, divide the Area by 2:</h3>

A = 20 ÷ 2

<em>A = 10 units²</em>

I hope this helps!

Write the equation of the line in slope-intercept form Slope=5/3 Y-Intercept=4

Eddi Din [679]

Answer:

$\sf y=\dfrac{5}{3}x+4$

Step-by-step explanation:

<u>Given:</u>

<u /> $\textsf{slope of $\dfrac{5}{3}$, and a y-intercept of $4$}$

⇒ Slope-Intercept Form: y = mx + b

<u>where:</u>

m is the slope
b is the y-intercept (when x = 0)

Substitute the given values:

$\sf\\ \implies y=mx+b\\\\\implies y=\dfrac{5}{3}x+4$

Pls help cause idk how to do this?!!?

tatiyna

U first start of with writing the numbers from small to greatest so it will be 45,53,53,54,60,62,63,67,68 after that your min will be your smallest, 45 and your Max is 68 than for you mid you start off at both ends with your finger ( if needed) to get your middle which in this case, it’s 60. Now for your Q1 u do the exact same thing for mid but instead of you start from 45 to 60 which gets u to 53 as ur Q1. Finally for your Q3 you you starting off at 60 and ending at 68 and doing the same thing again ur Q3 will be 63.

Factor 2a2b3 - 14ab + 16a

zhuklara [117]

Answer:

2a(b^3 - 7b + 8)

Step-by-step explanation:

I'm assuming that 2a2b3 is 2a2b^2. If not, this answer isn't correct.

Look at the whole numbers. Is there a number that divides into them evenly? Yes, 2, so you pull 2 from the problem and divide each number by 2. Do the same for each variable.

2a2b3 - 14ab + 16a

2(ab^3 - 7ab +8a)

2a(b^3 - 7b + 8)
