The length of the diagonal of the canvas is approximately 27 degrees.

The height of the rectangular canvas must reach 18 inches. It must form a 48 degrees angle with the diagonal at the top of the canvas.

<h3>Length of the diagonal Canvas</h3>

Therefore, the length of the diagonal can be found as follows:

Using trigonometric ratio,

cos ∅ = adjacent / hypotenuse

where

∅ = 48°

adjacent side = Height of the rectangle = 18 inches

hypotenuse = Length of the diagonal

Therefore,

cos 48° = 18 / h

cross multiply

h = 18 / cos 48°

h = 18 / 0.66913060635

h = 26.9005778976

length of the diagonal ≈ 27 inches

7th grade math, shouldn't be this hard.

Temka [501]

Answer:

x = 12

Step-by-step explanation:

Step 1: Add 9 to both sides.

$7x - 9 + 9 = 75 + 9$
$7x = 84$

Step 2: Divide both sides by 7.

$\frac{7x}{7} = \frac{84}{7}$
$x = 12$

Step 3: Check if solution is correct.

$7(12) - 9 = 75$
$84 - 9 = 75$
$75 = 75$

Therefore, x = 12.

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.

If we assume that we have $k$ independent variables and we have $j=1,\dots,j$ individuals, we can define the following formulas of variation:
