Answer:

**Answer:**

In a quadrilateral ABCD, ∠A = 100°, ∠B = 105° and ∠C = 70°, find ∠D.

Solution:

Here the sum of the four angles

or, ∠A + ∠B + ∠C + ∠D = 360°

We know, ∠A = 100°, ∠B = 105° and ∠C = 70°

or, 100° + 105° + 70° + ∠D = 360°

or, 275° + ∠D = 360°

∠D = 360° - 275°

Therefore, = 85°

Suppose human weights are normally distributed with mean 175 and standard deviation 36 pounds. A helicopter is evacuating people from a building surrounded by zombies, and this helicopter can fit 9 people and with a maximum weight of 1800 pounds, i.e., an average of 200 pounds per person. If 9 people are randomly chosen to be loaded on this helicopter, what is the probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)?

**Answer:**

x = 4y + 28

**Step-by-step explanation:**

x/4 - 7 = y

+7 +7

x/4 = y + 7

× 4 × 4

x = 4y + 28

**Answer:**

x = 4y + 28

**Step-by-step explanation:**

For this, you would need to simplify both sides of the equation, after isolating the variable.

The *probability* will be "

Given:

**Mean**,

- 9

**Standard deviation**,

- 0.6

**Number** of babies,

- 4

The **standard error** of sample will be:

→

hence,

→ P(4 babies will be between **8.4 - 9.6 pounds**)

Thus the above response is right.

Complete question:

Some sources report that the weights of full-term newborn babies in a certain town have a mean of 9 pounds and a standard deviation of 0.6 pounds and are normally distributed.

Answer: 0.7497

Step-by-step explanation:

Mean = 9

sd = 0.6

n = 4

P(4 babies will be between 8.4 and 9.6 pounds)

P(8.4 ≤ X ≤ 9.6)

Standard error of the sample (S. E) :

S. E = sd/√n

= 0.6 /√4

= 0.6/2

= 0.3

P(8.4 ≤ X ≤ 9.6)= ((P(8.4 - 9) / 0.3) ≤ X ≤ (9.6 - 9)/0.3)

P(8.4 ≤ X ≤ 9.6) = P(-2 ≤ X ≤ 2)

P(Z ≤ 2) - P(Z < - 2)

0.9772 - 0.2275 = 0.7497

that all chocolate-chip cookies sold have at least four chocolate-chip

parts?

Answer:

The answer is 2.1

Step-by-step explanation:

To find:

X = number of chips per cookies

Now use the Poisson distribution.

Now, starting from 0 make add four equations like below.

P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) = 0.021

After this multiple it by 100

And you get 2.1!

Therefore, the answer is 2.1
