A park charges $19 for one round of miniature golf and a reduced fee for each additional round played. If Tom paid $34 for 6 rou
iragen [17]

Answer:

$3

Step-by-step explanation:

Given that:

Park charge for one round = $19

Reduced fee for every additional round

Number of rounds played by Tom = 6

Amount paid = $34

Amount left after 1 round :

Amount paid - first round charge

$34 - $19 = $15

Number of rounds left = (6 - 1) = 5

Charge per additional round :

$15 / 5 = $3

I'm sorry I don't know how to do this problem, and its the only one I don't understand could anyone help me.
kolbaska11 [484]
You would multiply everything by 2. A dilation of 2 is an enlargement, or an increase in shape. If it was -2, it would be a reduction.

Multiply everything by 2:
(-2,3) = (-4,6) (3,4)= (6,8) (4,-1)= (8,-2)

I hope this helps you!

1. IQ scores of statistics students have a standard deviation less than 15. A. H0:σ≤15, H1:σ&gt;15 B. H0:σ≥15, H1:σ&lt;15 C. H0:
grandymaker [24]

Answer:

1) For this case we want to check if the population deviation is less than 15( alternative hypothesis) and the system of hypothesis are:

H0: \sigma \geq 15

H1: \sigma

B. H0:σ≥15, H1:σ<15

2) For this case we want to check if the population mean \mu is at most 70000 (alternative hypothesis) and the system of hypothesis are:

H0: \mu \geq 70000

H1: \mu

C. H0:µ≥70,000, H1:µ<70,000

3) For this case we want to check if the population proportion p of all internet users that make online purchases is higher than 0.5 (alternative hypothesis) and the system of hypothesis are:

H0: p \leq 0.5

H1: p >0.5

D. H0:p≤0.5, H1:p>0.5

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".  

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".  

Solution to the problem

1) For this case we want to check if the population deviation is less than 15( alternative hypothesis) and the system of hypothesis are:

H0: \sigma \geq 15

H1: \sigma

B. H0:σ≥15, H1:σ<15

2) For this case we want to check if the population mean \mu is at most 70000 (alternative hypothesis) and the system of hypothesis are:

H0: \mu \geq 70000

H1: \mu

C. H0:µ≥70,000, H1:µ<70,000

3) For this case we want to check if the population proportion p of all internet users that make online purchases is higher than 0.5 (alternative hypothesis) and the system of hypothesis are:

H0: p \leq 0.5

H1: p >0.5

D. H0:p≤0.5, H1:p>0.5
