dimaraw [331]3 years ago
3 0

Answer:

19,14

Step-by-step explanation:

x=5+y

x+ y= 33

we will solve using substitution

(5+y) +y= 33

5+y+y=33

5+2y=33

subtract 5 from both sides

2y=28

y=14

We got y now we will find what x is

for this, we will substitute y's value (14) into the first equation

x=5+(14)

x=19

we got x too

5. (5 points) Write the first 5 terms of the sequence if a1 = 9 and an-1 +n
Ivanshal [37]

Answer:

9,4,-1,-6,-11

Step-by-step explanation:

When n = 1: a(1+1) =a(1) +1

                   a(2) = -9 +1

                   a(2) = -8

When n = 2: a(2+1) =a(2) + 2

                   a(3) = -8 + 2

                    a(3) = -6

When n = 3: a(3+1) = -6 + 3

a(4) = -3

What is the greatest common factor of 3562, 15b, and 5b?
Inga [223]

Hey there!

3,562: 1, 2, 13, 26, 137, 274, 1781, 3562

15b: 1, 3, 5, 15, b

5b: 1, 5, b

☆ Not all of the terms have b in it so we know We can't have that as an answer. Only two of the numbers have b in it

The one you see most common would be the biggest/greatest common factor would be

Answer: GCF: 1 ✅

A binomial probability experiment is conducted with the given parameters. Use technology to find the probability of x successes
Nitella [24]

Answer:

P ( X < 4 ) = 0.1736706  

Step-by-step explanation:

Given:

- A random variable X follows a binomial distribution as follows,  

                                Where n = 8, and p = 0.6.

Find:

- P ( X < 4 )?

Solution:

- The random variable X follows a binomial distribution as follows:

                                        X ~ B ( 8 , 0.6 )

- The probability mass function for a binomial distribution is given as:

                                pmf = n^C_r ( p )^r (1-p)^(n-r)

- We are asked to find P ( X < 4 ) which is the sum of following probabilities:

               P ( X < 4 ) = P ( X = 0 ) + P ( X = 1 ) + P ( X = 2 ) + P ( X = 3 )

- Use the pmf to compute the individual probabilities:

P ( X < 4 ) = 0.4^8 + 8^C_1*(0.6)*(0.4)^7 + 8^C_2*(0.6)^2*(0.4)^6 + 8^C_3*(0.6)^3*(0.4)^5 .

     P ( X < 4 ) = 6.5536*10^-4 + 7.86432*10^-3 + 0.04128768 +0.12386304

Answer:                      P ( X < 4 ) = 0.1736706
