Solve (2 - x)^2 < 4/25

Answers

Answer 1

Answer:

8/5 < x< 12/5

Step-by-step explanation:

(2 - x)^2 < 4/25

Take the square root of each side

sqrt((2 - x)^2)  <±sqrt( 4/25)

Make two equations

2-x < 2/5    2-x > -2/5

Subtract 2 from each side

2-x-2 < 2/5 -2          2-x-2  > -2/5-2

-x < 2/5 -  10/5             -x > -2/5  - 10/5

-x < -8/5                         -x > -12/5

Multiply by -1, remembering to flip the inequality

x> 8/5                   x < 12/5

8/5 < x< 12/5

Find the slope (-7,4) and (-7,-8)

Answers

Answer: The slope for this line is not defined.

Step-by-step explanation: We can find the slope of a line using the formula m = y2 -y1/x2 - x1

here, (x1,y1) = (-7,4)

and, (x2,y2) = (-7,-8)

now, m= -8-4/-7+7

        m = -12/0

        So, the slope for this line is not defined as we are getting zero in the denominator.

How many combinations with repetition are allowed if n = 8 and r = 4?
256
330
1,680
65,536

Answers

Hello, the answer you are looking for should be “330” combinations :)

That should be the answer if I was wrong I’m very sorry

The combinations with repetition are allowed is 330

What is combination?

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items, where the order of the items is not fixed.

Given that, we need to find the number of combinations with repetition are allowed if n = 8 and r = 4

Combinations with repetition = C'(n, r) = (r+n-1)! / (r!(n-1)!)

= (8+4-1)! / 4!(8-1)!

= 11! / 4!7!

= 330

Hence, the combinations with repetition are allowed is 330

7 - 13a = 27 solve for A

Answers

Answer:

a = -20/13

Step-by-step explanation:

7 - 13a = 27

-13a = 20

a = -20/13

Let's check

7 - 13(-20/13) = 27

7 + 260/13 = 27

7 + 20 = 27

27 = 27

So, a = -20/13 is the correct answer!

A certain component is critical to the operation of an electrical system and must be replaced immediately upon failure. If the mean lifetime of this type of component is 100 hours and its standard deviation is 30 hours, how many of these components must be in stock so that the probability that the system is in continual operation for the next 2000 hours is at least 0.95?

Answers

Answer:

Step-by-step explanation:

From the given information:

Assuming we have an integer c to represent the components in the stocks.

Thus, the needed probability can be expressed as:

[tex]P(X_1+X_2+ ........ X_c \ge 2000)[/tex]

To break this down, we have:

[tex]P(\sum X_i \ge 2000) = P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )[/tex]

[tex]P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )= P (Z \ge 0.95 ) \ \ \ because \ Z_{0.05} = -1.65 \\ \\ \\ \dfrac{2000-100 n }{\sqrt{n \times 900}} = -1.65 \\ \\ \\ \dfrac{100\ n-2000 }{\sqrt{900n}} = 1.65 \\ \\ 100 n -1.65 \sqrt{900 n }-2000 = 0[/tex]

By solving the equation:

n = 23

Thus, relating to the needed condition; n ≥ 23

The needed number of the components that should be in stock should be  at least 23.

Answer:

SA = 112 cm²

Steps:

to solve this problem we have to calculate the surface area of the whole block and let be SA

first the surface area of the square pyramid:

the area of one triangle = (height × base)/2

given:

height = 6 cm

base = 4 cm

A = (6×4)/2

A = 24/2

A = 12 cm²

since it's a square triangle

then the surface area of the pyramid excluding the base:

Ap = A × 4

Ap = 12 × 4

Ap = 48 cm²

now the inferior part which is a rectangular prisme

Ar = 4(height×lenght)+lenght²

Ar = 4(3×4)+4²

Ar = 4×12+16

Ar = 48+16

Ar = 64 cm²

and now we can calculate the surface area of the whole block

SA = Ap + Ar

SA = 48 + 64

SA = 112 cm²
