Step-by-step explanation:

What is a34 of the sequence 9,6,3,..

r=a2-a1

r=6-9

r=-3

a34=a1+33.r

a34=9+33.(-3)

a34= 9-99

a34= -90

hope this helps !

Answer:

- 90

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

d = 6 - 9 = 3 - 6 = - 3 and a = 9, hence

$a_{34}$ = 9 - 3 × 33 = 9 - 99 = - 90

2 Points

beks73 [17]

Answer:

5 units

Step-by-step explanation:

Length AB,

Just apply the formula;

Length between two points =square root of [(difference in x coordinates)^2 + (difference in y coordinates)^2]

Length AB =square root of [(4 - 7)^2 + (-5 - - 9)^2]

Length AB =square root of [ (-3)^2 + (4)^2]

Length AB = square root of (25)

Length AB = 5 units

Marc is half as old as Tony and three times as old as Ben. If the sum of their ages is 40, how old is Marc?

Murljashka [212]

Answer:

Marc's age is 12

Step-by-step explanation:

Let

x ----> Marc's age

y ---> Tony's age

z ---> Ben's age

we know that

the sum of their ages is 40

$x+y+z=40$ -----> equation A

Marc is half as old as Tony

$x=\frac{y}{2}$

$y=2x$ ----> equation B

Marc is three times as old as Ben

$x=3z$

$z=\frac{x}{3}$ ----> equation C

substitute equation B and equation C in equation A

$x+2x+\frac{x}{3}=40$

solve for x

$\frac{10x}{3}=40$

$x=40(3)/10\\x=12\ years$

therefore

Marc's age is 12

g 3. Suppose X and Y are independent, Binomial random variables, respectively, with parameters (n1, p) and (n2, p). Calculate th

solong [7]

Answer and Explanation:

Solution:

Let x and y are independent, ariables.

The parameters of x and y are (n1, p) and (n2, p), respectively.

It means the sum of the independent binomial variable is itself a binomial random variable.

Consider probability of the event [ x = n1],

Denoted by: p(x=n1)

The function:

P(n1) = p(x = n1)

Over the possible value of x say, n1, n2, n3, …, is called frequency function.

The frequency function must satisfy.

∑I p (ni) = 1,

Where the sum is possible values of x.

Similarly,

Consider probability of the event [ y = n2],

Denoted by: p(y=n2)

The function:

P (n2) = p(y = n2)

Over the possible value of y say, n1, n2, n3, …, is called frequency function.

The frequency function completely describes the probabilistic nature of the random variable.
