A is not true, there are only 1 in the 70 inches tall column, and 3 in 69 1/2 column.

B is right, there are more dots in the right side of the data set.

C is not true, there is one dots in the 68 1/2, which means there is one player that is 68 1/2 inches.

D is right, because there are four dots in the column of 71

E is right, because there are total 6 different list/ column of dots.

F I am not sure, I think it is not true, because 74 inches is more like a outlier than 68 1/2

Right answer: B D E

2. Consider the quadratic equation 2x2 + 7x – 4 = 0.
erastova [34]
The value of the discriminant is the value of b^{2} -4ac located inside the square root of the quadratic formula. To find this, we simply look at the quadratic equation in standard form: a x^{2} +bx+c=0 and plug in the existing values into the quadratic formula (\frac{-b+- \sqrt{ b^{2}-4ac } }{2a}. Plug in the values of a b and c (2, 7, and -4, respectively) and get \frac{-7+- \sqrt{49-4(2)(-4)} }{4}.

Simplifying this, we get

\frac{-7+- \sqrt{81} }{4} =  \frac{-7+-9}{4} =  \frac{2}{4} or  \frac{-16}{4}

which equal 1/2 and -4, respectively.

A )The value of the discriminant is 81 (see work above)
B ) 2 solutions, discriminant is positive, and not equal to zero. They are both rational since sqrt 81 is a rational number
C ) 1/2 and -4 (see work above)

(HELP! I HAVE NO TIME) At 2pm, a store had sold 15 packs of toilet paper. By 5pm, the store had sold 57 packs of toilet paper. W
Novay_Z [31]

\mathrm {Hey, there!}

Let's solve your problem:

The answer would be 280%.

We know the following information:

2pm - 15 toilet paper rolls

5pm - 57 toilet paper rolls

We have to find the <u>percent rate of change.</u>

Here is how we will do this problem:

<h3><u>First, Set up a ratio:</u></h3>

Change in the quantity [15 - 57]

-------------------------------------

Original quantity [15]

57 - 15 = 42

<h3><u>Next, we will divide. the ratio.</u></h3>

Given quantity - 42

Number of packs sold at 2pm - 15

Fraction - 42/15

<h3><u>Convert the fraction to a decimal.</u></h3>

Fraction - 42/15

Decimal - 2.8

<h3><u>Make the decimal to a percent.</u></h3>

Decimal - 2.8

Percent - 28%

<u>Add a zero to the 28.</u>

<h2><u>Our answer is 280%</u></h2>

<h3></h3>
