Which of the following correlation coefficients represents the strongest

erik [133]

Answer:

$\boxed {\boxed {\sf -0.92}}$

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

If it is a negative number, the linear relationship is also negative. If it's positive, the relationship is positive.
The closer it is to -1 or 1, the stronger the relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.

Explain why the initial value of any function of the form<br> f(x) = a(bx) is equal to a.

Serggg [28]

Answer:

Step-by-step explanation:

f(x) = a(b^x), the initial value is always a, because a is independent of x , so when x changes only b^x changes.ex if a = 2, b = 3, and x = 0: f(0) = 2 (3^0) = 2 If x = 1, then f(1) = 2 (3^1) = 2 (3). If x = 2, then f(2) = 2 (3^2) = 2 (9), as you can see a still the same.

We want to compare the quality of three Tablet products: Tablet Product A has a Mean Time Between Failures (MTBF) 10,000 hours,

skelet666 [1.2K]

Answer:

The Availability of tablets A,B and C are equal

Step-by-step explanation:

Computation for Which tablet has better Availability

Using this formula

Availability of Tablet=MTBF/ ( MTBF + MTTR)

Where,

MTBF represent Mean Time Between Failures

MTTR represent Mean Time To Repair

Let plug in the formula

Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)

Availability of Tablet A= 0.999

Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )

Availability of Tablet B= 0.999

Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)

Availability of Tablet C= 0.999

Based on the above calculation the Availability of all the 3 tablets are equal

Therefore the Availability of tablets A,B and C are equal.

Can somebody please help me?

In order to be a triangle, the sum of two sides must be greater than the third side. (Just think about it for a bit and you will see why this has to be true). For example, could you have a triangle with side 3 inches, 4inches, and then a whopping 100 inches? No, because the other two sides are too short to fully connect a triangle!

So once you understand this, we can find the possible length <span>of </span>the missing side.

Let x be the length of the missing side in centimeters. The other two sides are 18cm and 40cm.

So one possible combination:

The sum of our two known lengths must be larger than the unknown length:

18 + 40 > x
58 > x

Therefore one constraint is that our third side has to be less than 58 centimeters.

Another combination:

18 + x > 40
x > 22

So another constraint is that our third side must be larger than 22 cm.

The last combination is pointless:

40 + x > 18

Since 40 is already larger than 18, then "40 + x" is obviously larger than 18.

So therefore our x has to be in this range:

22 < x < 58

In other words, our third side has to be larger than 22 cm, but less than 58 cm.

A room has an area of 60 square meters and a perimeter of 32 meters. What are the length and width of the room?

Nat2105 [25]

Length=10
width=6

6+6+10+10=32
6×10=60

look at the factors of 60 and see what two could make 60 but also equal 32
