keith made $306.00 for 18 hours of work at the same rate how many hours would he have to work to make $204.00
Mice21 [21]
306 / 18 = 17
So he's on $17 / hour

$204 / $17 = 12.
Therefore he'd make $204 in 12 hours.

It is believed that a stock price for a particular company will grow at a rate of $5 per week with a standard deviation of $1. A
IgorLugansk [536]

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = $5

For the alternative hypothesis,

µ < $5

number of samples taken = 10

Sample mean, x = (4 + 3 + 2 + 3 + 1 + 7 + 2 + 1 + 1 + 2)/10 = 2.6

To determine sample standard deviation, s

s = √(summation(x - mean)/n

n = 12

Summation(x - mean) = (4 - 2.6)^2 + (3 - 2.6)^2 + (2 - 2.6)^2 + (3 - 2.6)^2 + (1 - 2.6)^2 + (7 - 2.6)^2 + (2 - 2.6)^2 + (1 - 2.6)^2 + (1 - 2.6)^2 + (2 - 2.6)^2 = 30.4

s = √30.4/10 = 1.74

Since the number of samples is 10 and no population standard deviation is given, the distribution is a student's t.

Since n = 10,

Degrees of freedom, df = n - 1 = 10 - 1 = 9

t = (x - µ)/(s/√n)

Where

x = sample mean = 2.6

µ = population mean = 5

s = samples standard deviation = 1.74

t = (2.6 - 5)/(1.74/√10) = - 4.36

We would determine the p value at alpha = 0.05. using the t test calculator. It becomes

p = 0.000912

Which choice is equivalent to the expression below?<br><br> 6root7 minus 5xroot7 minus xroot7
butalik [34]

Answer:

Step-by-step explanation:

6root = 6^2= 6 x 6

= 36

6root7 = 36 x 7 = 252

Also,

5xroot7 = 5 x 7^7

= 5 x 49

= 245

Therefore,

6root7 - 5xroot7 - Xroot7 = 0

252 - 245 - 7x^2

= 7- 7x^2
