3 0

Answer:

C. A box plot is best for displaying the spread of data above and below the median, so Yuki should use a box plot.

Step-by-step explanation:

Neither dot plot nor histogram shows the median of data, but box plot it does. Also, box plots show the how spread data is from minimum value to first quartile, from first quartile to median, from median to third quartile and from third quartile to maximum value.

Write the following quadratic in standard form. Then identify a, b, and c.<br> y² - 7y + 6 = -6

Charra [1.4K]

Answer:

Therefore,

$y^{2}-7y+12=0$ ....Standard form.

$a=1\\b=-7\\c=12$ ......Numerical Coefficients.

Step-by-step explanation:

Given:

$y^{2}-7y+6=-6$

To Find:

a ,b , c

Solution:

Quadratic:

A quadratic equation is an equation of the second degree.

Meaning it contains at least one term that is squared.

The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

Here it is given as

$y^{2}-7y+6=-6$

Adding 6 on both the side we get

$y^{2}-7y+6+6=-6+6$

$y^{2}-7y+12=0$

Which is Quadratic Equation in STANDARD form Where,

$a=1\\b=-7\\c=12$

Therefore,

$y^{2}-7y+12=0$ ....Standard form.

$a=1\\b=-7\\c=12$ ......Numerical Coefficients.

Find m∠H. Put the answer below.<br> m∠H =

Pavlova-9 [17]

Answer:

30°

Step-by-step explanation:

$\tan (m\angle H) = \frac{IJ}{JH} \\ \\ \implies \: \tan (m\angle H) = \frac{ \sqrt{10} }{ \sqrt{30} } \\ \\\implies \: \tan (m\angle H) = \frac{{1} }{ \sqrt{3} } \\ \\ \implies \: \tan (m\angle H) = \tan 30 \degree \\ \\ \implies \: m\angle H = \boxed{30} \degree$

The area of a trapezoid is 69.6 in2 and its altitude is 8.7 in. Find the perimeter of the trapezoid if the sum of its legs is eq

Murljashka [212]

To answer this, you will find the sum of the bases by using the area of a trapezoid formula:

A = 1/2 x h x (b1 + b2) - You will represent the area of the 2 bases as x, because it says the sum of the bases so this can be
written as 1 term, x
69.6 = 1/2 x 8.7 x (x); solve for x
69.6 = 4.35x; divide both sides by 4.35
x = 16 in.

If 16 inches is the sum of the 2 bases and the sum of the legs, than you will double this answer to find the perimeter.

16 in x 2 = 32 inches

The perimeter is 32 inches.
