A noted psychic was tested for extrasensory perception. The psychic was presented with 2 0 0 cards face down and asked to determ
Natasha2012 [34]

Answer:

C. P- value < 0.04 0.05

Step-by-step explanation:

hello,

we were given the sample size, n = 200

also the probability that the psychic correctly identifies the symbol on the 200 card is

p=\frac{50}{200}= 0.25

using the large sample Z- statistic, we have

Z=\frac{p- 0.20}{\sqrt{0.2(1-0.2)/200} }

   = \frac{0.25-0.20}{\sqrt{0.16/200}}

    = 1.7678

thus the P - value for the hypothesis test is P(Z > 1.7678) = 0.039.

from the above, we conclude that the P- value < 0.04, 0.05

What is the salesperson's commission on a $900<br> sale if the commission rate is 25%?
Nadusha1986 [10]

Answer:

Amount of commission earned = $225

Step-by-step explanation:

Commission rate = 25%

Sales amount = $900

Find the amount of commission earned by the salesperson

Amount of commission earned = Commission rate × Sales amount

= 25% × $900

= 25/100 × $900

= 0.25 × $900

= $225

Amount of commission earned = $225

HELLPP ASAP!!!What are the exact solutions of x2 − 5x − 1 = 0 using x equals negative b plus or minus the square root of the qua
Mnenie [13.5K]

Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2

Step-by-step explanation:

The given quadratic equation is expressed as

x² - 5x - 1 = 0

The equation is already in the standard form of ax² + bx + c

The general formula for solving quadratic equations is expressed as

x = [- b ± √(b² - 4ac)]/2a

From the given quadratic equation,

a = 1

b = - 5

c = - 1

Therefore,

x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1

x = [5 ± √(25- - 4)]/2

x = [5 ± √29]/ 2

x = ( 5 + √29)/- 2 or x = (5 - √29)/2
