Step-by-step explanation:

(25x+8)°+(9x+2)°=180--->(1)(sum of angles on a straight line

(7y+5)°=(9x+2)°------------->(2)(vertical angles)

25x°+8°+9x°+2°=180°

34x°=170°

x=5°

from equation (2) substitute for x=5°

7y°+5°=9x°+2°

7y°+5°=9(5)°+2°

7y°=47°-5°

7y°=42°

y=6°

(x, y)=(5°,6°)

Answer:

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Step-by-step explanation:

Mean of the batch:

The mean of the batch is the sum of all values divided by the number of items. So

$M = \frac{199+204+201+197+195+204+200}{7} = 200$

Mean in the desired interval.

Standard deviation:

Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So

$S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18$

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Undefined Slope. Through (97 , 73)

Mnenie [13.5K]

Answer:

Equation of line through ( $(x_{1},y_{1})$ ) having undefined slope is given by

$\frac{y-y_{1}}{x-x_{1}}=tan\alpha$ where α =90°

Now ,it is given that line passes through (97, 93)

So , equation of line is

→ $\frac{y-73}{x-97}$ = tan 90°

As, tan 90°=1/0

$\frac{y-73}{x-97}=\frac{1}{0}\\$

→ (x-97)×1= (y-73)×0

→ x-97 =0

→ x=97 , which is the required equation of line.
