A sequence of 7 numbers starts with 8. The second number in the sequence is unknown and may be positive or negative. The third t
scoray [572]

Answer:

4

Explanation:

a_1=8,a_7=0

Since the third term is the sum of the two previous terms

a_3=a_2+a_1

a_7=a_6+a_5

a_7=a_5+a_4+a_4+a_3

Continuing in like manner

a_7=5a_3+3a_2

Since a_3=a_2+a_1

a_7=5(a_2+a_1+3a_2

a_7=5a_2+5a_1+3a_2

a_7=8a_2+5a_1

Recall: a_1=8,a_7=0

0=8a_2+5*8

8a_2=-40

a_2=-5

The sequence is therefore:

8,-5,3,-2,1,-1,0

The sum of the seven numbers is 4.

In a circle, what is the diameter in relation to the radius?
pogonyaev

Answer:

And by definition the radius would be lower than the diameter and we have the following relationship:

D= 2r

And then the best answer would be:

B  2r

Step-by-step explanation:

When we have a circle we know that the area is given by:

A= \pi r^2

And we also know that the diameter is the distance between two any points in the circle passing through the center.

And by definition the radius would be lower than the diameter and we have the following relationship:

D= 2r

And then the best answer would be:

B  2r

Help geometry is so hardddd I’m failing
Umnica [9.8K]

Answer:

The answer is 3. (4,-2)

Step-by-step explanation:

Without doing the math to determine the length of the segment(s), plot the points on a graph. The only one that falls on the line is (4,-2). If we call (4,-2) C, then AC is approximately 12 units, CB is approximately 6 units. 12:6 = 2:1

For a continuous random variable x, the probability density function f(x) represents
jarptica [38.1K]

Answer:

Option d.

Step-by-step explanation:

we know that

The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.

The curve is called the probability density function (abbreviated as pdf).

We use the symbol f(x) to represent the curve

therefore

The probability density function f(x) represents . the height of the function at  x.
