Answer:1 and 1/4

Step-by-step explanation:

Okay, let's see the given: 20/16

So, we can take out 16 from the top to make it 1 4/16

Now, we can simplify that by dividing the top and bottom by 2: 1 2/8

We can simplify that again to get 1 1/4

So the answer is 1 and 1/4

Can someone please help me with this question?

D. One reason, The others questions don't add up. Reason being, the perimeter of the garden is 4x+60, all of the other questions don't make up for that answer.
(I also can't read D, so I'm just assuming now.)

Nutka1998 [239]

Answer:

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis $H_a : \mu > 31$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 31 \ miles / gallon$

Generally

The null hypothesis is that the company's new sedan, the Libra, will have an average of $\mu = 31 \ miles / gallon$

This mathematically represented as

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis is that the company's new sedan, the Libra, will have an average better than $\mu = 31 \ miles / gallon$

This mathematically represented as

The alternative hypothesis $H_a : \mu > 31$
