Four runners competed in a 10 kilometer relay race. Each runner ran the same distance. What was the distance?

Answers

Ok i think they ran their own race so here goes nothing. Four runners so you need four in your problem so 4x now. Lets add the ten four ten kilometers i each race. So you final awnsere is 4x10=40 kilometers
this question doesn't make sense. are you asking how far did all 4 runners run together ??

Isaiah walks 3 miles due north, turns and then 5 miles due east. How far is he from his starting point?

Answers

The two segments of his walk can be considered the two legs
of a right triangle.

His distance from his starting point is the hypotenuse of the triangle,
so to find its length, we can call on Old Man Pythagoras to help us.

         Distance²  =  (3)² + (5)²

         Distance  =  √(9 + 25)  =  √34

                                            =  5.831 miles  (rounded) .


A family of 2 adults and 3 children goes to a play. Admission costs $8 per adult and $5 per child. What expression would show the total admission cost for the family?

Answers

the answer is $31 cause 5x3=15 and 8x2=16. add 15 and 16 together and then you get 31
A = 8
C= 5
2xA = 16
2x8 =16
3xC = 15
3x5=15
2a+c
16+15 = 31
Your answer would be 31 and it would be 2a+3c.

Please help!!!! Y=9600(1.31)x given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.?

Answers

answer 16.99%

We are given this function:

8700 is the initial amount.

1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.

1.04 * 100% = 104%

Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.

In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.

104% - 100% = 4%

This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.

1,16985856 * 100% ≈ 116,99%

116.99% - 100% = 16.99%

So, final solution is growth of 16.99%

There are three colored cookie jars. One jar is blue, another green and the last one pink. The blue jar contains 10 chocolate chip and 7 sugar cookies. The green jar contains 8 chocolate chip, 14 sugar and 11 peanut butter cookies. The pink jar contains 6 chocolate chip, 5 sugar and 9 peanut butter cookies. One of the three cookie jars is chosen at random. The probabilities that the blue jar, green jar, or pink jar will be chosen are 1⁄2 , 1⁄4 , and 1⁄4 , respectively. A cookie is then chosen at random from the chosen jar. What is the probability that the pink jar was chosen, if it is known that the cookie was a sugar cookie?

Answers

The probability that the pink jar was chosen, when it is known that the cookie was a sugar cookie is 0.167..

What is Bayes' theorem?

Suppose that there are two events A and B. Then suppose the conditional probability are:

P(A|B) = probability of occurrence of A given B has already occurred.

P(B|A) = probability of occurrence of B given A has already occurred.

There are three colored cookie jars. One jar is blue, another green and the last one pink.

  • The blue jar contains 10 chocolate chip and 7 sugar cookies.
  • The green jar contains 8 chocolate chip, 14 sugar and 11 peanut butter cookies.
  • The pink jar contains 6 chocolate chip, 5 sugar and 9 peanut butter cookies.

Thus the probability of chossing sugar is,

P=(1)/(2)*(7)/(17)+(1)/(4)*(17)/(33)+(1)/(4)*(5)/(20)

One of the three cookie jars is chosen at random. The probabilities that the blue jar, green jar, or pink jar will be chosen are 1⁄2 , 1⁄4 , and 1⁄4 , respectively.

Thus the probability for pink jar was chosen, when it is known that the cookie was a sugar cookie is,

\rm P=(P(pink\cap sugar))/(P(sugar))\n\rm P=(P(sugar| pink)P(Pink))/(P(sugar))

Put the values,

P=((1)/(4)*(5)/(20))/((1)/(2)*(7)/(17)+(1)/(4)*(17)/(33)+(1)/(4)*(5)/(20))\nP=0.167

Thus, the probability that the pink jar was chosen, when it is known that the cookie was a sugar cookie is 0.167.
