Answer: 7

<u>Step-by-step explanation:</u>

The 1st spinner can land on 2, 3, 4, or 5

The 2nd spinner can land on 2 or 3

The 3rd spinner can land on 6, 7, or 8

1st spinner + 2nd spinner + 3rd spinner:

2 + 2 + 6 = 10, 2 + 2 + 7 = 11, 2 + 2 + 8 = 12 --> 3 different sums

2 + 3 + 6 = 11, 2 + 3 + 7 = 12, 2 + 3 + 8 = 13 --> 1 different sum

This pattern follows where the only new sums are as follows:

3 + 3 + 8 = 14

4 + 3 + 8 = 15

5 + 3 + 8 = 16

This makes a total of 7 different sums.

Determine whether or not the given procedure results in a binomial distribution. If not, identify which condition is not met. Sp

Ostrovityanka [42]

Answer:

The procedure does results in a binomial distribution.

Step-by-step explanation:

For a binomial probability distribution to be applicable, certain conditions have to be met which are :

There must be a fixed number of observations ; here the number of observations are : 79

All observations must be independent ; the observations are independent ; odd or even

Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even

The probability of success must be equally likely for each observation.

Hence, the procedure results in a binomial probability distribution.

Given x² - 16x + 4 = 0:

arsen [322]

PART A
General formula of quadratic equation
ax² + bx + c = 0
To find the discriminant of the quadratic equation shown above, use this following formula.
d = $\sqrt{b^{2}-4ac}$

There is a quadratic equation below
x² - 16x + 4 = 0
therefore
a = 1
b = -16
c = 4

Plug in the numbers to the formula
d = $\sqrt{b^{2}-4ac}$
d = $\sqrt{(-16)^{2}-4(1)(4)}$
d = $\sqrt{(256-16}$
d = $\sqrt{240}$

Simplify
d = $\sqrt{16*15}$
d = $4 \sqrt{15}$
The value of the discriminant is 4√15

PART B
If the discriminant is less than zero (negative), the quadratic equation has imaginary solution.
If the discriminant is equal to zero, the quadratic equation has only one solution.
If the discriminant is more than zero (positive), the quadratic equation has two real solutions.

Because the discriminant of the quadratic equation is 4√15 and it's positive, <u>the quadratic equation has two real solutions.</u>
