Answer:
Well perimeter is adding up all the sides since it's a rectangle the first one is just 6 + 6 + 4 + 4 = 20 cm
The second would be 9 + 9 + 12 + 12 = 42 cm if this is not an option or if it is wrong let me know and I will try again
Answer:
The missing value is 2.9mm and cosine was used
Step-by-step explanation:
Given triangle is a right-angled triangle we can use trigonometric ratios to calculate the missing length.
In the given triangle,
Base = k
Hypotenuse = 15mm
Angle = 79
We will use trigonometric ratio which includes base and hypotenuse.
Using cosine,

Rounding off to nearest tenth

Hence,
The missing value is 2.9mm and cosine was used
Answer:
So If This Is Area You Take The Top Number And Subtract It By The Bottom Number To Get the Sides
Step-by-step explanation:
Answer:
0.82
Step-by-step explanation:
Given:
<em>A</em> be the event that an Internet user posts photos taken by themselves.
<em>B</em> be the event that an Internet user posts photos taken by themselves.
P(A) = 0.47
P(A) = 0.28
P(A or B) =
= 0.52
To find:
Conditional probability that an Internet user posts photos given that they post videos.
OR
P(A/B) = ?
Solution:
<em>Formula </em>to be used to find the required conditional probability:

For this,
is required.
<em>Formula</em>


Now, the required conditional probability is:

So, the answer is <em>0.82</em>.
