What is the value of the expression?<br> 2 1/4 divided by 1 2/5

ad-work [718]

Answer:

45/28

Step-by-step explanation:

Convert them to mixed fractions

(2 * 4 + 1) / 4 ÷ (1 * 5 + 2) / 5

8 + 1 / 4 ÷ 5 + 2 / 5

9/4 ÷ 7/5

Flip the second fraction and flip the sign - to multiply.

9/4 × 5/7

9 × 5 = 45

4 × 7 = 28

45/28

This could be left as a fraction or converted to a number:

A triangular plaque has side lengths of 8 inches, 13 inches, and 15 inches.

lianna [129]

<h3>Answer: A) 52 square inches</h3>

==========================================================

Explanation:

a = 8, b = 13, and c = 15 are the sides of the triangle

s = (a+b+c)/2 = (8+13+15)/2 = 18 is the semi-perimeter, aka half the perimeter.

Those values are then plugged into Heron's Formula below

$A = \sqrt{s*(s-a)*(s-b)*(s-c)}\\\\A = \sqrt{18*(18-8)*(18-13)*(18-15)}\\\\A = \sqrt{18*(10)*(5)*(3)}\\\\A = \sqrt{2700}\\\\A = \sqrt{900*3}\\\\A = \sqrt{900}*\sqrt{3}\\\\A = 30\sqrt{3}\\\\A \approx 51.9615\\\\A \approx 52\\\\$

The triangular plaque has an area of approximately 52 square inches.

Least square regressions are used to find the equation of <em>best fit between two variables</em>.

The equation of the least-squares regression line is: $\mathbf{y = 9.414 - 0.213x}$

The given parameters are:

$\mathbf{\bar x = 8}$

$\mathbf{\sigma_x = 4.47}$

$\mathbf{\bar y = 7.71}$

$\mathbf{\sigma_y = 1.20}$

$\mathbf{r = -0.793}$

The equation of the least-squares regression line is represented as:

$\mathbf{y = a + bx}$

Where:

$\mathbf{b = r \times \frac{\sigma_y}{\sigma_x}}$

$\mathbf{a = \bar y - b\bar x}$

So, we have:

$\mathbf{b = r \times \frac{\sigma_y}{\sigma_x}}$

$\mathbf{b = -0.793 \times \frac{1.20}{4.47}}$

$\mathbf{b = -0.213}$

$\mathbf{a = \bar y - b\bar x}$

$\mathbf{a = 7.71 - (-0.213) \times 8}$

$\mathbf{a = 9.414}$

So, the equation is:

$\mathbf{y = a + bx}$

$\mathbf{y = 9.414 - 0.213x}$
