First we convert the m to km by dividing the number by 1000. 1000m = 1 km.

150,000,000,000 / 1000 = 150,000,000 km

Now we divide 150,000,000/11,000,000 = 13.6363636364 au.

Solve the expression 94-x-67-x
Leni [432]

I guess it is simplifying the expression:

{ \tt{94 - x - 67 - x}} \\  = { \tt{94 - 67 + ( - x - x)}} \\  = { \tt{27 - (x + x)}} \\  = { \tt{27 - 2x}}

A hair salon in Cambridge, Massachusetts, reports that on seven randomly selected weekdays, the number of customers who visited
morpeh [17]

Answer:

a: 28 < µ < 34

Step-by-step explanation:

We need the mean, var, and standard deviation for the data set.  See first attached photo for calculations for these...

We get a mean of 222/7 = 31.7143

and a sample standard deviation of: 4.3079

We can now construct our confidence interval.  See the second attached photo for the construction steps.

They want a 90% confidence interval.  Our sample size is 7, so since n < 30, we will use a t-score.  Look up the value under the 10% area in 2 tails column, and degree of freedom is 6 (degree of freedom is always 1 less than sample size for confidence intervals when n < 30)

The t-value is: 1.943

We rounded down to the nearest person in the interval because we don't want to over estimate.  It said 28.55, so more than 28 but not quite 29, so if we use 29 as the lower limit, we could over estimate.  It's better to use 28 and underestimate a little when considering customer flow.

A total of 234 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t
lorasvet [3.4K]
234 = a + s                                                       s = students       a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get 
234 = a + 2a 
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold
