The one with 17

Step-by-step explanation:

Heads/tails=1/2 or 50%

20/36=56%

17/36=47%

20/36=64%

47% is closer to 50%

Answer:

Sin A = 3/5

Cos A = 4/5

Step-by-step explanation:

To find trigonometric ratio, recall SOHCAHTOA.

Thus:

Reference angle = <A

Opposite side to <A = 6

Adjacent side = 8

Hypotenuse = AB = √(8² + 6²) = 10 (pythagorean theorem)

Therefore,

✔️Sin A = Opp/Hyp

Sin A = 6/10 = 3/5

✔️Cos A = Adj/Hyp

Cos A = 8/10 = 4/5

Answer:

Range= (0,∞) and (-∞,0)

Step-by-step explanation:

Theres no real process to finding this out you just look at what type of function you have, your graph and your asymptote. We can see that the parts above the asymptote go up and towards ∞ and the part below goes down to -∞ but they can not cross 0

Answer:

(-infinity, -32/81] U (0, positive infintiy).

( use the sideways 8 symbol for infinity).

Step-by-step explanation:

The range is all possible y values in a function.

We can find the inverse of the function to find the range.

[tex]y = \frac{8}{ {x}^{2} - 7x - 8 } [/tex]

Replace x with y

[tex]x = \frac{8}{ {y}^{2} - 7y - 8 } [/tex]

Write the LCD as two binomial,

[tex]x = \frac{8}{(y + 1)(y - 8)} [/tex]

Multiply both sides by both binomial

[tex]x(y + 1)(y - 8) = 8[/tex]

[tex](xy + x)(y - 8) = 8[/tex]

[tex]x {y}^{2} - 8yx + xy - 8x = 8[/tex]

[tex]xy {}^{2} - 8yx + xy = 8 + 8x[/tex]

[tex]y( {x}^{2} - 8x + x) = 8 + 8x[/tex]

[tex] \frac{8 + 8x}{ {x}^{2} - 7x } [/tex]

[tex] {x}^{2} - 7x = 0[/tex]

[tex] {x}^{2} - 7x + 12.25 = 12.25[/tex]

[tex](x - 3.5) {}^{2} = 12.25[/tex]

[tex](x - 3.5) = 3.5[/tex]

[tex]x = 3.5[/tex]

Plug that in to the function to find it range.

We get approximately

[tex] - \frac{35}{81} [/tex]

So this means a point on our function must include -35/81.

The vertical asymptote is 0 so our y cannot be zero but it goes infinitely up so our range is

(-infinity, -32/81]U (0, positive infintiy).

( use the sideways 8 symbol for infinity).

Answer:

36.72

Step-by-step explanation:

Take 60% of 61.20. That is the markup.

60% * 61.20 = 60/100 * 61.2 = 3672/100 = 36.72

The markup is 36.72

Answer:

Since the calculated value of F = 1.4397 is less than the critical value of

F (9,9)= 2.4403 we conclude that the  first instructor's variance is smaller and reject H0.

Step-by-step explanation:

1)Formulate the hypothesis that first variance is equal or greater than the second variance

H0: σ₁²≥σ₂²  against the claim  that the first instructor's variance is smaller

 Ha: σ₁²< σ₂²

2) Test Statistic F= s₂²/s₁²

F= 84.8/ 58.9=  1.4397

3)Degrees of Freedom = n1-1= 10-1= 9  and n2 = 10-1= 9

4)Critical value   at 10 % significance level= F(9,9)= 2.4403

5)Since the calculated value of F = 1.4397 is less than the critical value of

F (9,9)= 2.4403 we conclude that the  first instructor's variance is smaller and reject H0.

Answer:

Step-by-step explanation: Lucy is correct because all of the squares are filled, and therefore instead of 1 square filled, 8 are, this is why lucy is correct :)

Answer:

Lucy is correct.

Step-by-step explanation:

We can see that the ENTIRE model is shaded ( all eight squares).

So Lucy is correct since she stated that 8 out of 8 (8/8) squares are shaded.

8/8 = 1, so whole.

1/8 would mean that only one out of eight squares is shaded, so Tim is NOT coorrect.

Answer: 18,720

Step-by-step explanation:

Let's take this equation

78,000(n)

n will equal 0.24, since we are trying to find 24% of 78,000

78,000(0.24)

18,720

Answer:

18720

Step-by-step explanation:

24/100 × 78,000

=18720

Answer:

15.00-2500...

20.00+55.00

Solution :

The formula for the linearization of a function [tex]$f(x)$[/tex] at a point [tex]$x$[/tex] = a is given as

[tex]$L(x)=f(a)+(x-a)f'(a)$[/tex]

Assuming the time is t and the distance travelled is [tex]$f(t)$[/tex], that makes the speed as [tex]$f'(t)$[/tex].

So substituting them in the linearization formula,

A. At t = 7 minutes

   f(7) = 2.5 km

    f'(7) = 0.5 kpm

  ∴ [tex]$L_7(t)=f(7)+(t-7)f'(7)$[/tex]

             [tex]$=2.5+(t-7)0.5$[/tex]

              [tex]$=2.5+0.5t-3.5$[/tex]

              [tex]$=0.5t-1$[/tex]

B. At t = 18 minutes

      f(18) = 14.8 km

    f'(18) = 0.8 kpm

  ∴ [tex]$L_{18}(t)=f(18)+(t-18)f'(18)$[/tex]

               [tex]$=14.8+(t-18)0.8$[/tex]

              [tex]$=14.8+0.8t-14.4$[/tex]

              [tex]$=0.8t-0.4$[/tex]

C. Substituting the value of t as 14 in both the linearization to determine the position at 14 minutes, we get

[tex]$L_7(14)=0.5(14)-1.0$[/tex]

          = 7 - 1

          = 6 km

[tex]$L_{18}(14)=0.8(14)+0.4$[/tex]

            = 11.2 + 0.4

            = 11.6 km

D. According to the linearization at 7, the distance travelled between the 7 minutes and 14 minutes is = 6 km - 2.5 km

                                           = 3.5 km

And between the 14 minutes and 18 minutes is = 14.8 km - 6 km

                                                                              = 8.8 km

This is an average speed of 0.5 kpm in the first interval and an average speed of 2.2 kpm.

Now, according to the linearization of 18, the distance travelled between the 7 minutes and the 14 minutes is = 11.6 km - 2.5 km

                                                           = 9.1 km

And between 14 minutes and 18 minutes is = 14.8 km - 11.6 km

                                                                       = 3.2 km

This gives an average speed of 1.3 kpm in the first interval and 0.8 kpm in the second interval.

Therefore, the second approximation is the better one since the average speed are closer to the actual readings in the second linearization.
