Answer:

The x would be 3.6

Step-by-step explanation:

If you see the relation or ration between the ABCD triangle and the EFGH then we can see that the side 2 is multiplied by 1.5 to get to 3. so you do the same thing to 2.4 and multiple that by 1.5 and 3.6.

Answer and Step-by-step explanation:

Essentially, the figure FEHG got scaled by a factor of 1.5, and turned into BADC

So 2.4 times 1.5 is 3.6

3.6 = x

A manufacturer knows that 14% of the products it produces are defective. Find the probability that among 7 randomly selected pro

diamong [38]

Answer: 0.6521

Step-by-step explanation:

According to the Binomial distribution , the provability of getting x successes in n trials is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where p=probability of getting success in each trial.

Let x denotes the number of defective products.

here , n=7 and p =0.14

Then, the probability that among 7 randomly selected products, at least one of them is defective= P(X ≥ 1) =1- P(X<1)

= 1- P(X=0)

$=1-^7C_0(0.14)^0(1-0.14)^7$

$=1-(1(1)(0.86)^7\ \[\because ^nC_0=1]$

$=1-0.347927822217$

$=0.652072177783\approx0.6521$

Hence, the probability that among 7 randomly selected products, at least one of them is defective is 0.6521 .

(3x+1)(x-2)+ax+b=3x^2+8x-5 Work out the values of a and b

Musya8 [376]

Answer:

a = 13, b = - 3

Step-by-step explanation:

Expand the left side and compare like terms on both sides

(3x + 1)(x - 2) ← expand using FOIL

= 3x² - 5x - 2

left side = 3x² - 5x - 2 + ax + b ← combine like terms

= 3x² + x(a - 5) + b - 2

right side = 3x² + 8x - 5

For the 2 sides to be equal then

a - 5 = 8 ( add 5 to both sides )

a = 13

and

b - 2 = - 5 ( add 2 to both sides )

b = - 3
