Answer:

The volume of the a sphere can be approximated by the rotation of a circle

Step-by-step explanation:

The volume of a sphere can be found by rotating a circle which is the cross section of the sphere about the x axis that is rotating x² + y² = a²

In the process of rotation, each cross section of the sphere generated will have a radius y from which the area of that cross section is π·y² = π·(a² - x²)

Therefore, integrating from +a to -a gives the volume of the sphere as π×[a³ - x³/3]ᵃ₋ₐ which is equal to 4/3·π·r³ (the exact volume of a sphere).

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x is greater than or equal to 86)? A. 0.
Lina20 [59]

Answer

0.975 is the probability value

Step-by-step explanation:

We start by getting the z score of 86

z-score = (x - mean)/SD

z-score = (86-98)/6 = -12/6 = -2

So we want to find the probability of z greater than or equal to 2

We shall be using the standard normal distribution table here

We have the answer as;

0.975

Typical misalignments between product design and operations include A. technology, reward systems, and infrastructure. B. techno
Lady bird [3.3K]

Answer:

(A) technology, reward systems, and infrastructure.

Explanation:

Misalignments can occur in technology, infrastructure, and reward systems, and also in marketing. A company is misaligned when people pursue goals and agendas that are incongruent with each other and do not combine to effectively advance a single purpose.

In fact, in marketing, misalignment is the scourge of the modern marketing department, and it’s no surprise why there is so many channels to manage with no way to predict the customer journey. Highly fragmented roles and teams executing on compressed time cycles. Intense pressure to drive business impact, while staff are drowning in disconnected data and unclear strategy.

Find EF if EM= x^2+25 and MF = 10x
N76 [4]

Answer:

x^2 + 10x + 25; (x + 5)^2.

Step-by-step explanation:

When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.

x^2 + 25 + 10x

= x^2 + 10x + 25

Since this can be immediately factored into (x + 5)^2, you have your answer.

Hope this helps!
