Answer: Histogram

You can eliminate the stem and leaf plot, since it tells you the amount of values.

You can eliminate the dot plot, since it also shows you the number of values.

You can eliminate the frequency table, since it calculates the frequency of a number.

Thus, the answer is the histogram.

I need to find side x in its simplest radical form using the special right triangles method

crimeas [40]

Answer:

\sqrt{6}

Explanation:

From the given diagram,

Hypotenuse sde = x

Opposite side = \sqrt{3}

Using the SOH CAH TOA identity

Sintheta = opposite/hypotenuse

Sin 45 = \sqrt{3}/x

x = \sqrt{3}/sin45

$\begin{gathered} x\text{ =}\frac{\sqrt[]{3}}{\sin 45} \\ x\text{ = }\frac{\sqrt[]{3}}{\frac{1}{\sqrt[]{2}}} \\ x\text{ = }\sqrt[]{3^{}}\cdot\sqrt[]{2} \\ x\text{ =}\sqrt[]{6} \end{gathered}$

Hence the value of x is \sqrt{6}

Mark is solving the equation 4x2 + 2x = -9 using the quadratic formula.

Masteriza [31]

4x^2 + 2x = -9
4x^2 + 2x + 9 = 0

remember that the form of quadratic is ax^2 + bx + c = 0

so
a = 4
b = 2
c = 9

Becky spent 3/4 of an hour practicing the piano.She spent 1/2 of that time practicing her recital piece. What fractional part of

Ber [7]

Answer:

3/8

Step-by-step explanation:

First,

convert 3/4 of an hour to minutes;

If 1 hr = 60 mins

then 3/4 of 1hr = $\frac{3}{4} *60\\ \\ =45 mins.Next, If 1/2 of 3/4 was spent practicing recital piece, it means that it is half of 45 mins;1/2 *45 = 22.5 minsLastly, convert the 22.5 mins into a fraction of an hour;22.5/60 = [tex]\frac{3}{8}$
