Question 4

Irina-Kira [14]

Answer:

Step-by-step explanation:

3x^2 + 8x = 2

3x^2 + 8x - 2 = 0

D = b^2+4ac

D = 8^2+4(3)(-2)

D = 64+(-24)

D = 64-24

D = 40

The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square r

qaws [65]

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).

The number of defective components produced by a certain process in one day has a Poisson

kakasveta [241]

Answer:

Step-by-step explanation:

Let X be the no of defective components produced by a certain process in one day

X is Poisson with parameter = 20

Y = no of components that can be repaired

Since each component to be repaired is independent of the other Y is Binomial with p =0.60

a) $P(x=15) = 0.051649$

b) P(Y = 10)= Binomial prob (15,0.6) for y =10

= $0.1859$

Here no of repairables X is binomial.

c) Prob for 15 produced and 10 repairable = product of a and b

= 0.009603
