Answer:

If x satisfy equation g mast be different of 3.

Step-by-step explanation:

-(x+3)+4(x-9)=gx-2

-x-3+4x-36=gx-2

3x-39=gx-2

3x-gx=-2+39

x(3-g)=37

If x satisfy equation g mast be different of 3.

The diagonal of a rectangle is 25 in. the width is 15 inches. what is the area of the rectangle? ​
klasskru [66]

Answer:

300

Step-by-step explanation:

The area of the rectangle can be calculated as follows

15√ 25^2 - 15^2

= 15√625-225

= 15√400

= 15 × 20

= 300

Hence the area of the rectangle is 300

2,6,18,...<br> Find the 8th term.<br> Find the 8th term.
maw [93]

Answer:

4378

Step-by-step explanation:

Its clearly given that each term is multiplied by 3

I.e- 2×3 = 6

6×3= 18

and so on....

so here the G.P series is a=2 and r=3

To find the 8th term ar^8-1

ar^7 = 2×3^7

= 2×2187

= 4378

Solve for b, then solve for each angle in the triangle
lesya692 [45]

We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

b+2b+(b+16)=180

then, solving for b, we get:

\begin{gathered} b+2b+(b+16)=180 \\ \Rightarrow4b+16=180 \\ \Rightarrow4b=180-16=164 \\ \Rightarrow b=\frac{164}{4}=41 \\ b=41 \end{gathered}

now that we have that b = 41, we can find the measure of each angle:

\begin{gathered} b=41 \\ 2b=2(41)=82 \\ b+16=41+16=57 \end{gathered}

Binomial distribution formula: P(x) = (n  k) p^k * (1 - p)^n - k

a) Probability that four parts are defective = 0.01374

P(4 defective) = (25 4) (0.04)^4 * (0.96)^21

P(4 defective) = 0.01374

b) Probability that at least one part is defective = 0.6396

Find the probability that 0 parts are defective and subtract that probability from 1.

P(0 defective) = (25 0) (0.04)^0 * (0.96)^25

P(0 defective) = 0.3604

1 - 0.3604 = 0.6396

c) Probability that 25 parts are defective = approximately 0

P(25 defective) = (25 25) (0.04)^25 * (0.96)^0

P(25 defective) = approximately 0

d) Probability that at most 1 part is defective = 0.7358

Find the probability that 0 and 1 parts are defective and add them together.

P(0 defective) = 0.3604 (from above)

P(1 defective) = (25 1) (0.04)^1 * (0.96)^24

P(1 defective) = 0.3754

P(at most 1 defective) = 0.3604 + 0.3754 = 0.7358

e) Mean = 1 | Standard Deviation = 0.9798

mean = n * p

mean = 25 * 0.04 = 1

stdev = \sqrt{np(1-p)}

stdev = \sqrt{(25)(0.04)(1-0.04)} = 0.9798

Hope this helps!! :)
