A recent survey reported that small businesses spend 24 hours a week marketing their business. A local chamber of commerce claim
kakasveta [241]

Answer:

Following are the responses to the given choices:

Step-by-step explanation:

In step 1:

State the zero and alternate test hypotheses. Insert underneath.

H_0 : \mu = 24: H_a : \mu < 24

H_0 Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies

H_1 There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.

In step 2:

Each test statistics meaning is calculated. Around two decimal places for your reply.

z=\frac{\bar{X}-\mu_{0}}{\frac{\sigma}{\sqrt{n}}}=\frac{23.2-24}{\frac{4.2}{\sqrt{88}}}=-1.787

In step 3:

Draw a start and write the decision.

Since it is observed that z=-1.787 < z_c=-1.64 it is then concluded that the null hypothesis is rejected.

Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.

Find the area of a parallelogram with base 15 yards and height of 21 2/3
VARVARA [1.3K]
To find the area of a parallelogram, you use the area formula:

Area = Base * Height

Then, all you have to do is substitute in your known integers and solve. Therefore:

Area = 15 * 21 2/3

When we multiply these two numbers, we get 

Area = 325 square yards or yardsyards^{2}

PLEASE HELP...!!!!!!!!!!
tangare [24]

Answer:

<em>5 and 10</em>

Step-by-step explanation:  

You have all the information you need to find the area of the circle and then subtracting that from 77 you'll have the area of the rectangle and will be able to figure out the length and height by looking at the answer options.

So the area of a triangle is 1/2(b x h) or (b x h)/2 so the base is 6 and the height is 9 so the area is 54/2 which equals 27. 77 - 27 = 50 so the area of the rectangle is 50. With the answer options provided I can see that <em>the height of the rectangle is 5 and the length is 10.</em>
