The straight line P has the equation y= 2x-5

Mathematics

Sunny_sXe [5.5K]4 years ago

Answer:

y=−x/2+2.

Step-by-step explanation:

The equation of the line in the slope-intercept form is y=2x−5.

The slope of the perpendicular line is negative inverse: m=−12.

So, the equation of the perpendicular line is y=−x/2+a.

To find a, we use the fact that the line should pass through the given point: 3=(−12)⋅(−2)+a.

Thus, a=2.

Therefore, the equation of the line is y=−x/2+2.

Answer:

It's an equilateral triangle, so all angles of the triangle are 60 degree.

6x-1 = 60

x= 10.167


11x+4

x= 10.545

Step-by-step explanation:

It's an equilateral triangle, so all angles of the triangle are 60 degree.

6x-1 = 60

6x = 60+1

x= 61/6 = 10.167


To solve 11x+4:

11x+4= 180-60

11x = 120-4

11x/11 = 116/11

x= 10.545

Serjik [45]
<span>Mean = 270 Standard deviation = 10 x = 255 Formula for z-score, z = (x - mean)/SD z = (255 - 270) / 10 => z = -15 / 10 => z = -1.5 So by referring to z-table, -1.5 correlates to 0.0668 that implies to 0.07 So 7% of the boxes of Apples weight less than 255oz. The percentage of boxes is in the range of 255 oz and 270 oz, Now calculating the requiring percentage 50% - 7% = 43%</span>

10C0 = 1

10C1 = 10

10C2 = 45

10C3 = 120

10C4 = 210

10C5 = 252

10C6 = 210

10C7 = 120

10C8 = 45

10C9 = 10

10C10 = 1
