Answer:

The fourth one.

Step-by-step explanation:

LR = 12, and LP = 7. Subtracting the two will give you the length of PR, which is 5.

Construct an accurate copy of triangle DEF. Check that EF = 4.6 cm.

garri49 [273]

Answer:

Angles on a straight line add up to 180°

Therefore, the interior angle D of the triangle = 180 - 150 = 30°

Draw a horizontal line of 8 cm - label DE.

Measure an angle of 30° from point D and draw a line.

Measure an angle of 90° from point E and draw a line.

These 2 lines will intersect at point F.

Erase the part of the lines that extend past the point of intersection.

A dashboard warning light is supposed to flash red if a car’s oil pressure is too low. On a certain model, the probability of th

PilotLPTM [1.2K]

Answer:

0.8462 or 84.62%

Step-by-step explanation:

The probability that the light flashes is given by the probability of it flashing when it should added to the probability of flashing when it should not:

$P(F) = P(O)*P(F_O)+P(N)*P(F_N)\\P(F) =0.10*0.99 + (1-0.10)*0.02\\P(F) = 0.117$

The probability that the oil pressure is low (driver needs to be concerned) is given by the probability that oil is low and the light flashes divided by the probability that the light flashes.

$P(O|F) =\frac{P(O_F)*P(O)}{P(F)} \\P(O|F) =\frac{0.99*0.10}{0.117}\\ P(O|F) =0.8462$

When the warning light goes on, there is a 0.8462 probability that the oil pressure is low.
