Answer:

Step-by-step explanation:

$3t-7=5t$

subtract 3t from both sides

$-7 = 2t$

multiply both sides by 3

$-21 = 6t$

so 6t = -21

Answer:

Proper Subsets = 1023

Step-by-step explanation:

Given $W= \{Hampton\ Hotels, Anytime\ Fitness, Subway, Jack\ in\ the\ Box, Supercuts, \\Jimmy\ Johns, Servpro, Denny's, Pizza\ Hut, 7-Eleven\}$

Required

Determine the proper subsets

Proper Subset (P) is calculated using;

$P = 2^n - 1$

Where

$n = number\ of\ elements$

In this case;

$n = 10$

So:

$P = 2^n - 1$

$P = 2^{10} - 1$

$P = 1024 - 1$

$P = 1023$

Hence;

<em>Proper Subsets = 1023</em>

Lelechka [254]

Answer:

Step-by-step explanation:

so llets find what 15% of 60% really is,

0.15*0.60=0.09

0.09 AKA 9%

so since 9% of people didn't show up we can subtract 9% from 60%

so 60-9=51

51% of setas are taken

to find the percent of seats still empty, subtract 100 form 51

100-51=49

49% of seats are still empty

Hope this helsp!

kirza4 [7]

Answer:

Z-score = -1.285

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 17.6 seconds

Standard Deviation, σ = 2.1 seconds

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

For x = 14.9, we have:

$z_{score} = \displaystyle\frac{14.9-17.6}{2.1} = -1.285$

A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.

Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]
