Mathematics

NeX [460]3 years ago

Step-by-step explanation:

I think we are missing some information (angle F or B or a side length would be great).

but just the right angles are not enough to calculate specific numbers. they would depend on the angle F or e.g. the side length of AB.

without any further information F and AB can be freely changed without changing the known facts, but it changes also C, B, G

so, all I can say is C = 180 - B.

and that G = B.

Find the missing length of the triangle.

allsm [11]

Hey there!

Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²

Here,

Base = 9 mm

Hypotenuse = 15 mm

Altitude = b

Hypotenuse² = Base² + Altitude ²

15² = 9² + b²

225 = 81 + b²

225 - 81 = b²

144 = b²

√144 = b

12 mm = b

Hope it helps ya!

Find the value of x in the equation below. 2(x - 8) = 24

Elza [17]

Answer:

Step-by-step explanation:

2(x - 8) = 24

2x - 16 = 24

Bringing like terms on one side

2x = 24 + 16

2x = 40

x = 40/ 2

x = 20

PLESE HELP 100 POINTS WILL MARK BRAINLIEST

MArishka [77]

Answer:

(3x3−6x2+7x−11)+(10x2−9x+4) = 10-2x

5x−15 = 5(x-3)

13x3−15x+7x−7 = 32-8x

3x3+4x2−2x−7 = 10-2x

3x3+4x4−2x2−7 = 14

(12x2−7x+8)−(4x2−5x+10) = 14-2x

16x2−12x+18 = 50-12x

In the field of quality control, the science of statistics is often used to determine if a process is "out of control." Suppo

Usimov [2.4K]

Answer:

a) P=0.0225

b) P=0.057375

Step-by-step explanation:

From exercise we have that 15% of items produced are defective, we conclude that probabiity:

P=15/100

P=0.15

a) We calculate the probabiity that two items are defective:

P= 0.15 · 0.15

P=0.0225

b) We calculate the probabiity that two of three items are defective:

P={3}_C_{2} · 0.85 · 0.15 · 0.15

P=\frac{3!}{2!(3-2)!} · 0.019125

P=3 · 0.019125

P=0.057375
