1. Subtract the flat fee 1,200-700 =500
2. 500 is what just the band made. Divide that by .16 (16%) to get the total ticket amount... 500 divided by .16 = 3,125

The total ticket amount was $3,125.

Here are summary statistics for randomly selected weights of newborn​ girls: n=185​,
Anna11 [10]

Answer:

The confidence  interval for the population mean μ​ is 32.487

Step-by-step explanation:

Given :

Number of weights of newborn​ girls n=185.

Mean \bar{x}=31.4 hg

Standard deviation s=7.5 hg

Use a 95​% confidence level i.e. cl=0.95

To find : What is the confidence interval for the population mean μ​?

Solution :

Using t-distribution,

The degree of freedom DF=n-1=185-1=184

\alpha=\frac{1-0.95}{2}

\alpha=0.025

The t critical value is t=1.973.

The confidence interval build is

CI=\bar{x}\pm(t\cdot \frac{s}{\sqrt{n}})

Substitute the values,

CI=31.4\pm(1.973\cdot \frac{7.5}{\sqrt{185}})

CI=31.4\pm(1.973\cdot 0.5514)

CI=31.4\pm(1.087)

31.4+1.087

32.487

Therefore, the confidence  interval for the population mean μ​ is 32.487

Determine the value of angle x and angle y
ss7ja [257]

Answer:

80

Step-by-step explanation:

Sum of interior angles of a polygon = (n-1)x180= (6-2)x180=720

Since this looks like a regular hexagon each interior angle =720/6=120

Hence the inside angle touching the line is 120 (inside the hexagon)

Since one side of the hexagon is parallel to the line, y and 20 form adjacent angle, sum 180,

Then y= 180-20=160

Then x=360-(160+120)=80 because sum of all angles round a point=360
