Answer:

Box 1 = -2 and Box 2=+1.......

Answer:

-2.5 if you have to write as a decimal and not a fraction.

Answer:

Step-by-step explanation:

4). Given functions are,

   [tex]f(x)=\frac{1}{3x}[/tex]

   For [tex]x=\frac{1}{12}[/tex]

   [tex]f(\frac{1}{12})=\frac{1}{3(\frac{1}{12})}[/tex]

             [tex]=\frac{1}{\frac{1}{4}}[/tex]

             [tex]=1\times\frac{4}{1}[/tex]

             [tex]=4[/tex]

   [tex]g(x)=\frac{1}{x^2}[/tex]

   For [tex]x=\frac{1}{5}[/tex],

   [tex]g(\frac{1}{5})=\frac{1}{(\frac{1}{5})^2}[/tex]

           [tex]=\frac{1}{\frac{1}{25}}[/tex]

           [tex]=25[/tex]

  [tex]f(\frac{1}{12})-g(\frac{1}{5})=4-25[/tex]

                       [tex]=-21[/tex]

5). f(x) = -2x² + 3x - 8

    f(k + 4) = -2(k + 4)² + 3(k + 4) - 8

                = -2(k² + 8k + 16) + 3(k + 4) - 8

                = -2k² - 16k - 32 + 3k + 12 - 8

                = -2k² - 13k - 28

Answer:

  C.  (-1, 2) and (4, 7)

Step-by-step explanation:

It may be simplest just to try the answer choices.

We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.

__

The second equation can be written in vertex form as ...

  y = (x -1)^2 -2

This equation is not satisfied by the points of choice B.

  Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.

However it is a good match for the points of choice C.

  Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True

The appropriate choice is ...

  (-1, 2) and (4, 7)

Answer:

P(A and B) = 0.44

Step-by-step explanation:

Venn probabilities:

Suppose that we have two events, A and B. The probability of A and B is:

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

In which [tex]P(A \cup B)[/tex] is P(A or B).

In this question:

[tex]P(A) = 0.53, P(B) = 0.39, P(A \cup B) = 0.48[/tex]

Then

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.53 + 0.39 - 0.48 = 0.44[/tex]

So

P(A and B) = 0.44

Answer:

189 components must be sampled.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.

This means that [tex]\sigma = 16[/tex]

How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?

n components must be sampled.

n is found when M = 3. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]3 = 2.575\frac{16}{\sqrt{n}}[/tex]

[tex]3\sqrt{n} = 2.575*16[/tex]

[tex]\sqrt{n} = \frac{2.575*16}{3}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575*16}{3})^2[/tex]

[tex]n = 188.6[/tex]

Rounding up:

189 components must be sampled.

Answer:

  A)  3 1/4

Step-by-step explanation:

Your calculator can help with this.

__

  3/4 + ((1/3)/(1/6)) -(-1/2)

  = 3/4 + ((2/6)/(1/6)) + 2/4

  = 5/4 + 2/1

  = 3 1/4

Q) 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2) = ?

→ 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2)

→ 3/4 + {(1/3) × (6/1)} - ( - 1/2)

→ 3/4 + 6/3 - ( - 1/2)

→ {(3/4) + (6/3)} + 1/2

→ 11/4 + 1/2

→ (11 + 2)/4 = 13/4

→ 3 1/4

Hence, option (A) is the answer.

Factorise:- d² + 14d + 40

[tex] \rightarrow [/tex] d² + 10d + 4d + 40 = 0

[tex] \rightarrow [/tex] d(d + 10) + 4(d + 10) = 0

[tex] \rightarrow [/tex] (d + 10)(d + 4) = 0

[tex] \therefore [/tex] Either, d + 10 = 0 => d = -10 and d + 4 = 0 => d = -4

Answer:

The answer to the first question is B.

The answer to the second question is C.

Answer:

3: B or 1/4

4: C or 15%

Step-by-step explanation:

3: There are 8 letters in Geometry and 2 E's in the word so it would be 2/8, but then you would simplify it and you will get 1/4.

4: 0.85 in a percentage is 85%. So 85% that WILL rain.

100 - 85 = 15, thus there is a 15% probability it will NOT rain.

Hope that helps :)

Answer:

A, B, and E.

Step-by-step explanation:

We know that one vertex is at (5, 4), and each side of our square is 3 units long.

Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3  units (if those vertexes are connected by the diagonal of the square).

Also remember that the distance between two points (a, b) and (b, c) is:

distance = √(  (a - c)^2 + (b - d)^2)

So we need to find the distance between our point and all the ones given in the options:

A) the distance between (5, 4) and (5, 1) is:

distance = √( (5 - 5)^2 + (4 - 1)^2) = 3

Then point (5, 1) can be a vertex.

B) The distance between (5, 4) and (5, 7) is:

distance = √( (5 - 5)^2 + (4 - 7)^2) = 3

Then (5, 7) can be a vertex.

C)  The distance between (5, 4) and (7, 8) is:

distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20

Point (7, 8) can not be a vertex.

D)  The distance between (5, 4) and (2, 6) is:

distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13

Point (2, 6) can not be a vertex.

E) The distance between (5, 4) and (2, 1) is:

distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3

Then point (2, 1) can be a vertex.
