Answer:

The zebra needs 1.66 Km of a head start to tie the cheetah in the race.

Step-by-step explanation:

The top speed of the cheetah is 96 Km/h.

If the cheetah ran for 5 Km, it would need

5 / 96 hours

The top speed of a zebra is 64 Km/h.

Running the same time, the zebra would travel a distance of:

5 / 96 * 64 = 3.33 Km

It would need an additional distance to tie the cheetah of 5 - 3.33 = 1.66 Km

The zebra needs 1.66 Km of a head start to tie the cheetah in the race.

Answer:

μ₀ = 89

Step-by-step explanation:

A study has shown that  23 %  of all College textbook cost 95 $ or more,  then if the area under the bell shape curve is 23 % in the right tail, then

z(score ) = 0,74          ( 0,23 ≈  0,2296  from z table )

Then z(score) = ( x - μ₀ ) / σ

0,74  =  ( 95 -  μ₀ ) / 8,5

0,74*8,5 = 95 -  μ₀

6,29 - 95 = - μ₀

μ₀ = 88,71

μ₀ = 89

Find the number of cheesecakes that this local bakery expects to sell in a day.

A) 20 B) 14.1 C) 14.16 D) 10

Answer:

Given the data:

14.1

Step-by-step explanation:

X : ____0 ___5 ____10 _____15 _____20

P(X): _0.06 _0.2 __0.13 ___ 0.08 ____ 0.53

Exoectwd number of cheesecakes to be sold per day :

E(X) = ΣX*P(x)

E(X) = (0*0.06) + (5*0.2) + (10*0.13) + (15*0.08) + (20*0.53)

E(X) = 0 + 1 + 1.3 + 1.2 + 10.6

E(X) = 14.1

Answer:

X intercept: 8,0

Y intercept ( 0,-4)

Step-by-step explanation:

Answer:

(-8,0) , (0,4) and our answer is D which is not given in the choices i even attached the graph so you can double check.

Step-by-step explanation:

Arrange the equation into the standard form [tex]y=mx+c[/tex]

so,

[tex]3x-6y=-24\\3x+24=6y\\y=\frac{3x+24}{6} \\\\y=\frac{3x}{6} +\frac{24}{6} \\\\y=\frac{x}{2}+4[/tex]

[tex]y=mx+c[/tex]

if we compare we get c=4 where c is the y-intercept now for the x-intercept which means the coordinate should be (x,0) because x-intercept means the function cuts/intersects the x-axis at (x,0) so we put the coordinate and the value of m(slope) and c(y-intercept) in our equation.

[tex]y=\frac{x}{2}+4\\\\ put (x,0) in the function\\\\0=\frac{x}{2} +4\\\frac{x}{2}=-4 \\x=-8[/tex]

so finally our x-intercept is (-8,0) and y-intercept is (0,4)

Answer:

Step-by-step explanation:

Since, Victor takes 5 minutes to cover number of laps = 3

Relation between the time (t) and number of laps (l) covered shows a proportional relationship.

l ∝ t

l = kt

k = [tex]\frac{l}{t}[/tex]

where k = proportionality constant

For t = 5 minutes and l = 3 laps,

k = [tex]\frac{3}{5}[/tex] = 0.6

Therefore, equation will be,

l = 0.6t

For t = 1 min,

l = 0.6 laps

For l = [tex]1\frac{1}{5}[/tex] ≈ 1.2 laps

1.2 = 0.6t

t = 2

For t = 6 min,

l = 0.6(6)

l = 3.6 laps

Therefore, table will be,

Laps              0.6        [tex]1\frac{1}{5}[/tex]         3.6          

Time (min)      1            2           6

Answer:

k=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

2+5k=3k−4−2

Step 1: Simplify both sides of the equation.

2+5k=3k−4−2

2+5k=3k+−4+−2

5k+2=(3k)+(−4+−2)(Combine Like Terms)

5k+2=3k+−6

5k+2=3k−6

Step 2: Subtract 3k from both sides.

5k+2−3k=3k−6−3k

2k+2=−6

Step 3: Subtract 2 from both sides.

2k+2−2=−6−2

2k=−8

Step 4: Divide both sides by 2.

2k/2=−8/2

k=−4

Step-by-step explanation:

Answer:

The value is  [tex]P(X \le 60 ) = 0.00135[/tex]  

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 90 \ minutes[/tex]

   The standard deviation is  [tex]\sigma = 10[/tex]

Generally  1 hours =  60  minutes

  Generally the probability that the exam will be completed in one hour or less is  

     [tex]P(X \le 60 ) = 1 - P(X > 60 )[/tex]

Here

     [tex]P(X > 60 ) = P( \frac{ X - \mu }{ \sigma } > \frac{ 60 - 90 }{ 10 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P(X > 60 ) = P( Z> -3 )[/tex]

From the z -distribution table the probability of  ( Z> -3  )

      [tex]P( Z> -3 ) = 0.99865[/tex]

[tex]P(X > 60 ) = 0.99865[/tex]

=>   [tex]P(X \le 60 ) = 1 - 0.99865[/tex]

=>   [tex]P(X \le 60 ) = 0.00135[/tex]  

Answer:

V(t) = 18t²-18t-360

Step-by-step explanation:

Given the equation of motion of particle expressed as:

s(t) = 6t³-9t²-360t

Velocity is the change in displacement of a body with respect to time.

V(t) = ds(t)/dt

V(t) = 3(6)t²-2(9)t¹-360

V(t) = 18t²-18t-360

Hence the function of the velocity is V(t) = 18t²-18t-360

Answer:

No.

It doesn’t pass through the origin point.

Step-by-step explanation:

Remember that for a graph to represent a proportional relationship, it must meet the following three criteria:

Our graph is indeed a line.

It is also not vertical or horizontal.

However, it does not pass through the origin point (0, 0).

Therefore, this graph is not a proportional relationship.

Answer:

y = [tex]-\frac{1}{3}[/tex] x – 1 (see below)

Step-by-step explanation:

First, refer to the slope-intercept formula:

y = mx + b

The variable m represents the slope. The slope is the steepness of the line. The variable b represents the y-intercept. The y-intercept is the point where the line intersects the y-axis.

The slope is already given, so you can plug it in:

y = [tex]-\frac{1}{3}[/tex] x + b

To find the y-intercept, you will need a point on the line. Because there is already a point in which you are required to intersect, you might as well use that point. Also, keep in mind that it's the simplest way to get a line through that point.

First, plug in the point's values (6, –3) into your almost-complete formula:

y = [tex]-\frac{1}{3}[/tex] x + b

–3 = [tex]-\frac{1}{3}[/tex] (6) + b

–3 = –2 + b

–3 + 2 = b

b = –1

Now that you have your y-intercept, your equation is complete:

y = [tex]-\frac{1}{3}[/tex] x – 1

Answer:

1499

Step-by-step explanation:

Given there are 1500 team in a tournament .

Game is played between exactly 2 team

And looser immediately exclude from tournament.

We calculate the number of game :

We constant divide the number of teams by 2 and the quotient is divided for the next division until we get quotient as 1 and the remainder as 0.

And each time we divide, if the divident is even add quotient to the number of game in tournament if add then quotient + 1 to the number of game in the tournament.

2 | 500

2 | 750

2 | 375

2 | 187

2 | 93

2 | 46

2 | 23

2 | 11

2 | 5

2 | 2

     1

Therefore, 750 + 375 + 187 + 1 +93 + 1 + 46 + 1 +23 + 11 + 1 + 5 + 1 + 2 + 1

                   = 1499

Therefore, total number of games is 1499.
