E line plot below shows the amount of water Rickayla drinks in 10 days. Part a: how many cups of water did Rickayla drink in 10

Levart [38]

Answer:

$Total = 23\frac{1}{4}$ cups

Step-by-step explanation:

Incomplete question.

See attachment for line plot

Required

Total cups drank in 10 days

The number of x at the top of each dataset represent the frequency (i.e. number of cups) drank on that day.

To get the total, we simply multiply this frequency by the accompanying dataset.

So, we have:

$Total = 2 * 1\frac{1}{2} + 1 * 1\frac{3}{4} + 2 * 2 + 2 * 2\frac{3}{4} + 3 * 3$

Express fractions as improper fraction

$Total = 2 * \frac{3}{2} + 1 * \frac{7}{4} + 2 * 2 + 2 * \frac{11}{4} + 3 * 3$

Evaluate each product

$Total = 3 + \frac{7}{4} + 4 + \frac{11}{2} + 9$

Take LCM

$Total = \frac{12+ 7+16+22+36}{4}$

$Total = \frac{93}{4}$

$Total = 23\frac{1}{4}$

What’s the answer to this question?

kobusy [5.1K]

The answer is 16.

First of all, you need to divide 4 by 1/4.

4/1 / 1/4 = 1.

15 - 1 + 2

Next, you go from left to right with addition and subtraction, so subtract 1 from 15 first.

15 - 1 = 14

14 + 2

Finally, add 14 and 2.

14 + 2 = 16.

Using the Factor Theorem, which of the polynomial functions has the zeros 2, radical 3 , and negative radical 3 ?

Alja [10]

Using the factor theorem, it is found that the polynomial is:

$f(x) = x^3 - 2x^2 - 3x + 6$

Given by the first option

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

Given a polynomial f(x), this polynomial has roots $x_{1}, x_{2}, x_{n}$ using the factor theorem it can be written as: $a(x - x_{1})*(x - x_{2})*...*(x-x_n)$ , in which a is the leading coefficient.
