The inequality graphed is the one in the first option.

<h3>Which inequality is represented by the graph?</h3>

On the graph we can see a solid parabola, the parabola opens downwards, and we can see that the vertex of the parabola is on the point (-1, 5).

And the shaded region is above the parabola.

Then the inequality is of the form:

y ≥ parabola.

By knowing where is the vertex, we know that:

parabola = -a*(x + 1)^2 + 5

Then the correct option is the first one.

I need help on this..... can anyone help me?

Answer and step-by-step explanation:

Tim Carter money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 50 hours so next 10 hours (50-40) = 10 * (1.5*5.15)

= 10* 7.725 = $77.25

Total money he made:

= 206 + 77.25 = $283.25

Jeese Jones money amde:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 47.5 hours so next 7.5 hours (47.5-40) = 7.5 * (1.5*5.15)

= 7.5 *7.725 = $57.9375

Total money Jeese Jones made:

= 206 + 57.9375 = $263.9375

Barbara Burns money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because Barbara Burns works for 44 hours so next 4 hours (44-40) = 4 * (1.5*5.15)

= 4* 7.725 = $30.9

Total money Barbara Burns made:

= 206 + 30.9 = $236.9

What are the conditions a sample needs to meet before you can assume it's binomial and that it approximates a normal distributio

Gemiola [76]

Answer:

1) $np\geq 5$

2) $nq = n(1-p)\geq 5$

Other conditions that are important are:

3) n is large

4) p is close to 1/2 or 0.5

Step-by-step explanation:

1) Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

2) Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n, p)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

In order to apply the normal apprximation we need to satisfy these two conditions:

1) $np\geq 5$

2) $nq = n(1-p)\geq 5$

Other conditions that are important are:

3) n is large

4) p is close to 1/2 or 0.5
