(x,y)
if x repeats with a differnt y then it is not a function

A. none of them repeat, it's a function
B. none of them repeat, it's a function

both of them are functions

Suppose the function F(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake fo

navik [9.2K]

Answer:

The variable c represents the domain as it is the independent variable.

The domain of the function F(c) is given by c ≥ 0.

So, only positive values for the input make sense.

The upper limit of the domain is +∞ and lower limit is 0.

It is not possible for the team to earn $50.50 as it will be only multiple of 2.

Step-by-step explanation:

If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is

F(c) = 2c ..... (1)

The variable c represents the domain as it is the independent variable. (Answer)

The domain of the function F(c) is given by c ≥ 0. (Answer)

Solve for x squared - 12x+59=0

dalvyx [7]

We solve the equation $x^2 - 12x + 59 = 0$

First we use $x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6i}\left(\frac{59}{11}\right)$ in order to compute our answer and then we use Justin Bieber's I close my eyes and I can see a better day Theorem that says that

$The\ solutions\ to\ x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6(i)}= 0 \\ \\ \\ \ are\ x=6+\sqrt{23}i,\:x=6-\sqrt{23}i$

Here is a proof of Justin Bieber's I close my eyes and I can see a better day Theorem which uses the advanced techniques of mathematicians:

$x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6(i)}= 0 \\ 
x^2 - 12x + 59 = 0\\ 
\implies x = \frac{-(-12) \pm \sqrt{(-12)^2 - 4(1)(59)} }{2(1)} \\ 
x = \frac{12 \pm \sqrt{144 - 236} }{2} \\
x = \frac{12 \pm \sqrt{-92} }{2} \\
x = \frac{12 \pm 2\sqrt{-23} }{2} \\
x = 6 \pm 2 \sqrt{23} i \\$

Which of the following is equivalent to 7-2(x + 2) <-4 - 3(1 - x)?

puteri [66]

Answer:

2 < x

Step-by-step explanation:

7-2(x + 2) <-4 - 3(1 - x)

Distribute

7 - 2x-4 < -4 -3 +3x

Combine like terms

3 -2x < -7+3x

Add 2x to each side

3 -2x+2x< -7+3x+2x

3 < -7+5x

Add 7 to each side

3+7 < -7+7+5x

10 < 5x

Divide each side by 5

10/ 5 < 5x/5

2 < x

Select the most accurate statement regarding the normal distribution. Group of answer choices It is always the appropriate distr

PSYCHO15rus [73]

Answer:

There is a 95% chance that values will be within ±2 standard deviations of the mean.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this question:

According to the empirical rule, 95% of the measures are within 2 standard deviations of the mean. So the correct statement is:

There is a 95% chance that values will be within ±2 standard deviations of the mean.
