mixas84 [53]

Solution:

we are given that

The fairy tale spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $.80.

You have $50 to spend at the fairy tale spectacular including admission.

Suppose you took x ride, then we can write.

So the inequality can be written as below:

$32.50+0.80x\leq 50$

PartB:

Now lets solve the inequality

$32.50+0.80x\leq 50\\\\ 0.80x\leq 50-32.50\\\\0.80x\leq 17.50\\\\x\leq 21.875$

Hence you can take a maximum of 21 rides.

babunello [35]

Answer: 0.345

Step-by-step explanation:

Given: The the setup for this hypothesis test:

$H_0:p=0.65\\\\H_a:p$

Since , the alternative hypothesis is left tail , so the test is left tail test.

$P_0=0.65\\\\Q_0=1-0.65=0.35\\\\p=\dfrac{126}{200}=0.63$

The test static for population proportion is given by :-

$z=\dfrac{p-P_0}{\sqrt{\dfrac{P_0Q_0}{n}}}\\\\\Rightarrow\ z=\dfrac{0.63-0.65}{\sqrt{\dfrac{0.65-0.35}{126}}}=−0.409878030638\approx-0.4$

The p-value of z = $P(z$
