josh wanted to buy a bicycle but didn't have enough money. After josh told his troubles to sam slick, sam said,"I can fix that.

see that fence? each time you jump that fence, i'll double your money. There's one small thing though: you must give me $32 each time for the priviledge of jumping." Josh agreed, jumped the fence, received his payment from sam slick, and paid sam $32. Repeating the routine twice more, josh was distressed to find that, on the last jump,after sam had made his payment to josh, josh had only $32, with which to pay sam and so had nothing left. Sam, of course, went merrily on his way, leaving josh wishing that he had known a little more about mathematics.

Answer:If he had less than 32 he couldn't jump. If he had 64 he would have not lost nor won on each jump -- he gets 64 in total after each jump. If he had more than 64 he would have won.

Now, 3 jumps give him a result of 32. After 2 jumps he had 32(pay)+16(doubled)=48. After the first jump he had 32+24=56. Before that he had 32+28=$60. 5 more dollars and he could have build his way to richness!

The test statistic of z= -2.39 is obtained when testing the claim that p<0.52.
krek1111 [17]

Considering the situation described, we have that:

a) The critical value is of z = -1.645.

b) Since the test statistic is less than the critical value, we should reject the null hypothesis H0.

<h3>What is the critical value?</h3>

We have a left-tailed test, as we are testing if the proportion is less than a value. Hence the critical value is z with a p-value equals to the significance level, hence z with a p-value of 0.05, hence z = -1.645.

<h3>What is the decision?</h3>

Considering the test statistic, for a left-tailed test, we have that:

  • Less than the critical value: Reject H0.
  • Equal or greater: Do not reject.

In this problem, z = -2.39 is less than -1.645, hence we should reject the null hypothesis H0.

Subtract j from 9, then subtract 3 from the result
Lera25 [3.4K]

Answer:

(9-j)-3

Step-by-step explanation:

Let's start from the beginning and subtract j from 9. Because the word "from" is used, 9 will be the first number and j will be the second number.

We have 9-j

Now, we have to subtract 3 from the final answer. So, we have (9-j)-3
