Answer:

ok so lets find the difference on the table

from 5 to 8 is goes up 250.5(668-417.5)

so that means 3 tickets goes 250.5 so lets divide by 3

250.5 divide by 3=83.5 per ticket

83.5*6=501

501

Hope This Helps!!!

Answer:

Equation : $83.50x = Cost of the tickets

(where x = number of tickets)

Cost of 6 tickets : $501

Step-by-step explanation:

I'm not sure if this is the way they want you to do it, but what I did is :

1) Solve a proportion to figure out the cost of 1 ticket

5/417.50 = 1/x

5x = 417.50(1)

5x/5 = 417.50/5

x = 83.50

So, the cost of 1 ticket is $83.50

2) Create an equation

If x equals the number of tickets :

83.50x = Cost of the tickets

3) Solve for 6 tickets

83.50(6) = Cost of the tickets

501 = Cost of the tickets

Substitute x for the number of tickets, which is 6 and you'll get $501 :)

Hello,

Step-by-step explanation:

heigth of the equilateral triangle:

$h=3*\dfrac{\sqrt{3}}{2}$

Area of the triangle:

$A=\dfrac{6*3\sqrt{3} }{2*2} =\dfrac{9\sqrt{3} }{2} \\\\$

Area of the disk:

$S=\pi*4^2=16\pi\\\\$

Probability:

$p=\dfrac{9\sqrt{3} }{2*16*\pi}=0.15506125....\approx{15.5\%}$

Answer:

Step-by-step explanation:

Orchestra Seats: Balcony seats + 7
Orchestra Seats: 600
Balcony Seats: 120
Total Amount of Sales: 13,560

A.) 600 x 20 = 12,000

120 x 27 = 3,240

12,000 + 3,240 = 15,240

B.) 600 x 13 = 7,800

120 x 20 = 2,400

7,800 + 2,400 = 10,200

C.) 600 x 18 = 10,800

120 x 25 = 3,000

10,800 + 3,000 = 13,800

D.) 600 x 11 = 6,600

120 x 18 = 2,160

6,600 + 2,160 = 8,760

Finger [1]

Answer:

y = ln(x) -5

Step-by-step explanation:

To translate the graph of a function 5 units down, subtract 5 from the function value.

ln(x) is translated 5 down when you make it ln(x) -5.

y = ln(x) -5

A survey reports that 67% of college students prefer to drink more coffee during the exams week. If we randomly select 80 colleg

Akimi4 [234]

Answer:

The probability that at most 50 say that they drink coffee during exam week is 0.166.

Step-by-step explanation:

The random variable X can be defined as the number of college students who prefer to drink more coffee during the exams week.

The probability of the random variable X is p = 0.67.

A random sample of n = 80 college students are selected.

The response of every students is independent of the others.

The random variable X follows a Binomial distribution with parameters n = 80 and p = 0.67.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

np ≥ 10
n(1 - p) ≥ 10

Check the conditions as follows:

$np=80\times 0.67=53.6>10\\n(1-p)=80\times (1-0.67)=26.4>10$

Thus, a Normal approximation to binomial can be applied.

$X\sim N(np, np(1-p))$

The mean of the distribution of X is:

$\mu=np=80\times 0.67=53.6$

The standard deviation of the distribution of X is:

$\sigma=\sqrt{np(1-p)}=\sqrt{80\times 0.67\times (1-0.67)}=4.206$

A Normal distribution is a continuous distribution. So, the probability at a point cannot be computed for the Normal distribution. To compute the probability at a point we need to apply the continuity correction.

Compute the probability that at most 50 say that they drink coffee during exam week as follows:

Apply continuity correction:

$P(X\leq 50)=P(X$

$=P(X$

*Use a z-table for the probability.

Thus, the probability that at most 50 say that they drink coffee during exam week is 0.166.
