Kiley was solving the equation: y= x ÷ 2 + 1 . Her first three y numbers were 3, 5, and 7. Her friend Gia said the ordered pair for the next number would be (16,9). Kiley disagrees. Why is Kiley correct?

Answer:

0.0009 probability of obtaining exactly 1 head

Step-by-step explanation:

For each toss, there are only two possible outcomes. Either it is a head, or it is not. The probability of a toss being a head is independent of any other toss. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A fair coin is tossed 14 times.

Fair coin means that it is equally as likely to be heads or tails, so [tex]p = 0.5[/tex]

14 times means that [tex]n = 14[/tex]

What is the probability of obtaining exactly 1 head?

This is P(X = 1).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{14,1}.(0.5)^{1}.(0.5)^{13} = 0.0009[/tex]

0.0009 probability of obtaining exactly 1 head

Answer:

See below.

Step-by-step explanation:

An inverse function has the x and y coordinates switched. For example, if a function has point (1, 3), then the inverse function has point (3, 1).

Let's find the ordered pairs of the inverse function. We take all the ordered pairs of the original function:

(1, 3), (7, 4), (8, 6), (9, y)

Now we switch x and y in each ordered pair to come up with the inverse function.

The inverse function has these ordered pairs:

(3, 1), (4, 7), (6, 8), (y, 9)

For a relation to be a function, a value used as an x-coordinate can appear only once.

The last ordered pair is (y, 9). For the inverse relation to be a function, y cannot be 3, 4, or 6.

Answer:

inverse of ordered pair (1,3),(7,4),(8,6)and (9,y)

is (3,1),(4,7),(6,8)and(y,9)

Answer:

If anders flips one coin, he has a 1/2 chance of heads.

if he flips two, he has to get to heads, which the chances are 1/2 and 1/2

So multiply 1/2*1/2

Answer:

D. The mean is 52.

Step-by-step explanation:

In order to find the mean, you add up all of the numbers and then divide that answer by how many numbers there are.

43+50+60+36+47+52+78=416

416/8=52

Answer:

D. The mean is 52.

Step-by-step explanation:

Add all numbers in the set:

36+47+50+50+52+60+78= 416

Now, divide the sum by how many numbers are in the set; in this case, there are 8 numbers so:

416÷ 8= 52

9 x^2 + 24 x + 16 or (3 x + 4)^2

Step-by-step explanation:

Simplify the following:

(3 x + 4) (3 x + 4)

(3 x + 4) (3 x + 4) = (3 x + 4)^2:

Answer: |

| (3 x + 4)^2

or

Expand the following:

(3 x + 4) (3 x + 4)

(3 x + 4) (3 x + 4) = (3 x + 4)^2:

(3 x + 4)^2

(3 x + 4) (3 x + 4) = (3 x) (3 x) + (3 x) (4) + (4) (3 x) + (4) (4):

3 3 x x + 4 3 x + 4 3 x + 4 4

3 x×3 x = 3×3 x^2:

9 x^2 + 4 3 x + 4 3 x + 4 4

3×3 = 9:

9 x^2 + 4 3 x + 4 3 x + 4 4

4×3 = 12:

9 x^2 + 4 3 x + 12 x + 4 4

4×3 = 12:

9 x^2 + 12 x + 12 x + 4 4

4×4 = 16:

9 x^2 + 12 x + 12 x + 16

Grouping like terms, 9 x^2 + 12 x + 12 x + 16 = 9 x^2 + (12 x + 12 x) + 16:

9 x^2 + (12 x + 12 x) + 16

12 x + 12 x = 24 x:

Answer: |

Answer: its cubic

Step-by-step explanation:

The graph below is an example of a cubic type of function. Option C is correct.

A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.

1. A parabola is the graph of a quadratic function. As a result, the presented graph is not a quadratic function graph.

2. A straight line is represented by a linear function. As a result, the presented graph is not a linear function graph.

3. A cubic function's end behavior is opposite at both ends. We can see that the presented graph satisfies these requirements.

4. A square root function's graph resembles a half parabola. As a result, it can't be the graph of the square root function.

The graph below is an example of a cubic type of function.

Hence,option C is correct.

Answer:

Step-by-step explanation:

Set up synthetic division, starting with x - 1 as the divisor, and then (from that) 1:

1     /    1   0    0    -1               The coefficients of x^2 and x are zero here.

               1     1      1

     --------------------------

         1     1      1      0              

Since the remainder is zero, 1 is a root and x - 1 is a factor of the original

x^3 - 1 = 0.

Answer:

Expression that is to be deducted will be (6x + 3).

Step-by-step explanation:

Let the linear expression that is to be subtracted from the given expression (5x + 3) is (ax + b).

After subtracting (ax + b) from (5x + 3) the remainder is (-x)

(5x + 3) - (ax + b) = -x

(5x - ax) + (3 - b) = -x

(5 - a)x + (3 - b) = -x

By comparing coefficients,

(5 - a) = -1

a = 5 + 1

a = 6

(3 - b) = 0

b = 3

Therefore, expression that is to be deducted from (5x + 3) will be (6x + 3).
