I would say 19.
If you take out the 6s and just look at the rest you have 4, 9, 14.
It is adding 5 each time and just have a 6 between each one.
So logically I would say 19.

According to a study by de Anna students, the height for Asian adult males is normally distributed with an average of 66 inches

Maslowich

A. X ~ N(66, 6.25)

b. $z_{1} =\frac{65-66}{2.5}=-0.4$
$z_{2} =\frac{69-66}{2.5}=1.2$
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403

c. z= 0.524 and -0.524
$0.524=\frac{X-66}{2.5}$
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4

Use Pascal's triangle to find the coefficient of the third term in the expansion of (a + b)2.

Alexxandr [17]

Answer:

Step-by-step explanation:

(a+b)^2

using Pascal triangle

1 1

1 2 1

1 3 3 1

so the third term in the expansion of (a+b)^2

we use

1 2 1

a^2 + 2ab+b

hence the coefficient of third term is 1

option B is collect
