A horse race has 14 entries and one person owns 5 of those horses. assuming that there are no​ ties, what is the probability tha
makvit [3.9K]
We know that
<span>entries------------ > 14 in total.
the owner has----------->  5 horses.

if each horse has the same probability of winning, then the probability that the owner's horses will come in first, second, third, fourth </span>and fifth will be as follows: <span>
we have 5 spots. 

the probability that one of those 5 horses will be first is 5/14
the probability that one of the remaining 4 horses will be second is 4/13.
the probability that one of the remaining 3 horses will be third is 3/12.
</span>the probability that one of the remaining 2 horses will be fourth is 2/11.<span>
the probability that the remaining horse will be fifth is 1/10. 

the total probability is [5/14 * 4/13 *3/12 *2/11 *1/10]
(120/240240)=1/2002=0.0004995

the answer is 0.0004995</span>

ivolga24 [154]

Answer:

4 units to the left

Step-by-step explanation:

y = a (x - h)² + k

The h is a horizontal translation of <em>h</em> units.

For h > 0, move right

For h < 0, move left

The function y=-x^2+65x+256 models the number y of subscribers to a website, where x is the number of days since the website lau
Wittaler [7]

Answer:

y = 30x+290

Step-by-step explanation:

Given

y=-x^2+65x+256

Required

The linear function of a competitor's website

On day 1, both websites have the same subscribers.

This implies that:

y=-x^2+65x+256

Substitute: x =1

y=-(1)^2+65*1+256

y=-1+65+256

y=320

This implies:

(x_1,y_1) = (1,320)

On day 34, both websites have the same subscribers.

This implies that:

y=-x^2+65x+256

Substitute: x =34

y=-(34)^2+65*34+256

y=-1156+2210+256

y=1310

This implies:

(x_2,y_2) = (34,1310)

To calculate the linear function of the competitor, we have:

(x_1,y_1) = (1,320)

(x_2,y_2) = (34,1310)

Calculate slope (m)

m = \frac{y_2 - y_1}{x_2 -x_1}

m = \frac{1310 - 320}{34-1}

m = \frac{990}{33}

m = 30

The equation is then calculated as:

y = m(x - x_1) + y_1

This gives:

y = 30 * (x - 1) + 320

Open bracket

y = 30x - 30 + 320

<em></em>y = 30x+290<em> --- This represents the linear function of the competitor's website</em>

An object is moving at a speed of 230 feet per week. Express this speed in inches per minute. Round your answer to the nearest h
Kruka [31]

Answer:

0.02 inches per minute

Step-by-step explanation:

1 Week = 10080 minutes

Formaul: multiply the time value by 10080  to find the minutes in a week or do it the long way 60x24x7 = 10080

230/10080 = 0.02281746031 or 0.02 rounded to nearest hundert.
