Answer:

Step-by-step explanation:

1. Cost of each notebook = 3.79

Cost of 8 notebooks = 3.79 x 8 = 30.32

Amount gave to cashier = 50

Change = 50 - 30.32 = 19.68

10.A noted psychic was tested for ESP. The psychic was presented with 200 cards face down and askedto determine if the card was
lions [1.4K]

Answer:

Step-by-step explanation:

The sample proportion \hat p = \dfrac{50}{200}

\hat p = 0.25

The null hypothesis and the alternative hypothesis:

H_o: p = 0.20  \\ \\  H_1 : p > 0.20

Thus; the test statistics is:

Z = \dfrac{\hat p - p_o}{\dfrac{p_o(1-p_o)}{n} }

Z = \dfrac{0.25 -0.20}{\sqrt{\dfrac{0.20(1-0.20)}{200} }}

Z = \dfrac{0.05}{\sqrt{\dfrac{0.16}{200} }}

Z = \dfrac{0.05}{\sqrt{0.0008 }}

Z = 1.768

P-value = 2 × P(Z< - 1.768)

From the z tables

P-value = 2 × 0.03853

P-value = 0.07706

Thus, the p-value is 0.05 < P-value < 0.10

Solve the inequality and graph the solution on the line provided.<br> 3 + 2x &gt; 5
ElenaW [278]

Answer:

x>1

Step-by-step explanation:

In order to do this, we can take the inequality:

3+2x>5

now there are constants on both sides meaning we can combine them like the following:

3+2x>5

-3      -3

------------

2x>2

Now we can simplify

2x/2>2/2

therefore, the answer is x>1

In order to graph this on a line you would need to put in a circle which is not filled in because x isn't <u>equal to and greater than</u> 1 so we put in a blank circle and since x is always going to be greater than 1, we would put a line that keeps going on.

You would put this line to the right of 1

o----------->

1 2 3 4 5 6

that is how the line would look like
