Answer:

The polynomial will be P(x) = - 5 (x + 2)²(x - 3)

Step-by-step explanation:

The degree of the polynomial P(x) is 3 and it has zeros at x = - 2 with multiplicity 2 and at x = 3 with multiplicity 1.

Therefore, (x + 2)² and (x - 3) are the factors of the equation.

Let the polynomial is

P(x) = a(x + 2)²(x - 3) ........... (1)

Now, the polynomial passes through the point (2,80).

So, from equation (1) we gat,

80 = a(4)²(-1)

⇒ a = - 5

Therefore, the polynomial will be P(x) = - 5 (x + 2)²(x - 3) (Answer)

In a histogram, the proportion of the total area which must be to the left of the median is:
Lana71 [14]

Answer:

A. exactly 0.50

Step-by-step explanation:

We have been given a statement. We are asked to choose the correct option about given statement.

We know that every histogram has 5 points summary.

1st point is known as minimum point, 2nd point is first quartile, 3rd point is median, 4th point is upper quartile and 5th point is maximum point.

In a normal distribution 25% of the data points are to the left 1st quartile, 50% of the data points are to the left of median and 75% of the data points are to the left 2nd quartile.

50\%=\frac{50}{100}=0.50

Therefore, exactly 0.50 of the total area which must be to the left of the median.

HELP ME PLSSSSSS!!!!!!!!!!!!!!!
xxMikexx [17]

Answer:

<em>No.</em>

Step-by-step explanation:

<em>5c-6=4-3c</em>

<em>5c-6+6=4-3c+6 Add six to both sides</em>

<em>5c=-3c+10 Simplify</em>

<em>5c+3c=-3c+10+3c Add 3c to both sides</em>

<em>8c=10 Simplify</em>

<em>8c/8=10/8 Divide both sides by 8</em>

<em>c=5/4 <<< Simplify and you get that</em>

<em>So they (Student A) are/is not correct.</em>

Hope this helps, have a good day. c;
