Answer:

$given \: that \: the \: cost \: of \: orchestra \: is \: three \: times \: of \: balcony \: ticket \\ let \: the \:cost \: of \: balcony \: \: ticket \: be \:x \\ so \: the \: cost \: of \: orchestra \: ticket \: sold \: be \: 3x \\ the \: total \: income = 3640 \\ \\ so \: the \: equation \: formed \: = > 148(3x)+ 76(x) = 3640 \\ = > 444x + 76x = 3640 \\ = > 520x = 3640 \\ = > x = \frac{3640}{520} \\ = > x = 7$

$so \: orchestra \: ticket \: = 444x = 444 \times = 3108 \\ and \: balcony \: ticket \: = 76x = 76 \times 7 = 532$

FOR PROOF = 3108+532 = 3640 total income

Joe heard from a reliable source that only 22% of people actually sleep 8 hours or more per night. You do a survey and find 58 o

Juliette [100K]

Answer:

95% Confidence interval: (31.32%,47.04%)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 148

Number of people who sleep for 8 hours or longer, x = 58

$\hat{p} = \dfrac{x}{n} = \dfrac{58}{148} = 0.3918$

95% Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting the values, we get:

$0.3918\pm 1.96(\sqrt{\dfrac{0.3918(1-0.3918)}{148}})\\\\ = 0.3918\pm 0.0786\\\\=(0.3132,0.4704)=(31.32\%,47.04\%)$

(31.32%,47.04%) is the required 95% confidence interval.

Arisa [49]

Answer:

Perimeter = 18 units

Step-by-step explanation:

one side = 4

other side² = 3² + 4² + 25

The solution to 5 - 3x> 35 is either x>-10 or -10> x. which solution is correct

velikii [3]

It should be x < -10 because when you divide by a negative number the inequality sign flips.
