Mathematics

Irina18 [472]3 years ago

3+2=5

80/5=16

16x3=48

16x2=32

(48+32=80)

therefore the ratio =48:32

which can be simplified to

24:16

12:8

6:4

and then back to  3:2

hope this helped :)

The 3:2 ratio can be calculated by dividing the total by the sum of the factors (3 + 2) i.e. 80/5 = 16 
<span>Then multiply the factors by the answer above (i.e. 3 x 16 and 2 x 16) </span>

<span>48:32
hope this helps you ! =')</span>

Plz help!
GuDViN [60]

Answer:

5x - y = 27

Step-by-step explanation:

Slope is the direction of line and it is calculated as,

Slope = \frac{y-y_{1}}{x-x_{1}}&#10;

where (x₁, y₁) is any two points on the line.

Here, we have given that

Slope = 5  and (x₁, y₁) = (5, -2)

∴  5 = \frac{y-(-2)}{x-5}&#10;

⇒ 5(x - 5) = y + 2

⇒ 5x - 25 = y + 2

⇒ 5x - y = 27

Hence, the equation of a line is: 5x - y = 27

Please help<br> if x = 3 and y=-4 find x2 + y2 and x2 -y2
lions [1.4K]
1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2


Hope this helped, have an awesome day!

Consider a biased coin with the probability of turning up head 0 &lt; p &lt; 1. We flip the coin 10 times and get a sequence of
qwelly [4]

Answer:

Probability of obtaining 6H and 4T = 0.2051

Step-by-step explanation:

Since for a fair coin,

Probability of obtaining Head = 0.5

p = 0.5

q = 1-p = 0.5

Probability of obtaining 6H and 4T = 10C6 (p)^6(q)^4 = 210*0.5^6*0.5^4

P(6H, 4T) = 0.2051
