Hello!
You first have to find the area of the square grid
To find this you multiply the sides
14 * 14 = 196
Next you have to find the area of the triangle
To find the area of a triangle you use the equation

h is height
b is base
Put in the values you know

Multiply

The area of the triangle is 49 inches squared
You divide the area of the triangle by the area of the square
196 / 49 = 4
The answer is 4 triangles
Hope this helps!
The 4 is the tenth million place
Answer:
The number of words per page.
Step-by-step explanation:
We're given the time per page. The book could have 10 words or it could have 1,000 words. We wouldn't know until given that information.
Answer:
0.0818.
Step-by-step explanation:
This question can be solved using the binomial theorem because the probability of success is fixed.
Total adults = n = 20
Required attempts = r = 12
Probability of success = p = 3/4 = 0.46
Binomial Theorem formula:
P(X=r) = nCr * p^r * (1-p)^(n-r).
Substituting the values:
P(X=12) = 20C12 * 0.46^12 * (1-0.46)^8
P(X=12) = 125970 * 0.46^12 * (0.54)^8 = 0.0818 (to the nearest 3 significant figures).
So the probability that exactly 12 people use their smart phones in meetings or classes out of 20 is 0.0818!!!
