Let x be the number of adult tickets sold, such that 2x is the number of student tickets sold.

2x + x = 384, since the number of adult and student tickets add up to the total number of tickets.
3x = 384
x = 128

So, there are 128 adult tickets, leaving 256 student tickets sold.

I believe it is 128. I may be wrong but if there are 384 tickets sold and there were 2 times more student tickets sold than adult then there are 128 tickets lift over to be adult tickets

Write the slope-intercept form of the given line. Include your work in your final answer.

Degger [83]

Answer:

y=1x+-1

Step-by-step explanation:

y=mx+b

m=slope which is 1/1 because it is rise over run (rising 1, running 1)

b=y-intercept form which is -1 because that is where the line meets the y axis

A wedge of cheese is shaped like a triangular prism. The wedge of cheese is 7 inches tall. The base of the cheese is shaped like

Gala2k [10]

Answer:

193 in

Step-by-step explanation:

Volume of a triangular prism:

The volume of a triangular prism is the base area multiplied by the wedge, that is:

$V = A_bw$

The base area is one half times the triangle base times it's height, so:

$V = 0.5*b*h*w$

The wedge of cheese is 7 inches tall.

This means that $w = 7$

The base of the cheese is shaped like a triangle with a base of 11 and a height of 5 inches.

This means that $b = 11, h = 5$

Volume:

$V = 0.5*b*h*w = 0.5*11*5*7 = 192.5$

Rounding, approximately 193 in.

Which number line shows the solution to 2/3 x - 5>3 ? PLS I NEED IT FOR RIGHT NOW

nataly862011 [7]

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about</h3>

inequality
algebra
PEMDAS

first note: it will be more easy if we solve the inequality first

so let's solve it together

$\frac{2}{3} x - 5 > 3$

$\frac{2}{3} x > 8$

$2x > 24$

$x > 12$

so what we get

we get that x is greater than 12

<h2>so the answer would be d</h2>

Assume that women have heights that are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches.

Maurinko [17]

Answer:

Q3 = 65.7825.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 63.6, \sigma = 2.5$
