Answer:

68m2

Step-by-step explanation:

First you can split the shape into three different ones (as shown in my incredibly awful sketch ><)

Then you can multiply the length x width.

so 3x3 and 3x3 and 5x10

The sum of all the answers in 68 ^^

hope this helps for further problems <33

eduardo baked 150 muffins 1/5 of the muffins are banana 1/2 of the muffins are blueberry the rest are strawberry, how many muffi

Answer:

45 strawberry muffins

Step-by-step explanation:

In order to solve this equation you are going to have to multiply 150 by 1/5 bananas and 1/2 blueberry in order to get how much strawberry muffins were made. So first we are going to convert 1/5 and 1/2 into decimals:

1/5 = 0.2

1/2 = 0.5

Now we are going to multiply 0.2 and 0.5 by 150 in order to figure out how much banana and Blueberry muffins were made:

0.2 * 150 = 30

0.5 * 150 = 75

So 30 banana muffins were made and 75 blueberry muffins were made, now that we know this we are going to add 30 and 75 together and subtract the answer from 150. THe reason we are subtracting 75 + 30 from 150 is because we are trying to segregate the strawberry muffins from the total number:

75 + 30 = 105

now we subtract:

150 - 105 = 45

So the number of strawberry muffins made was 45.

I hope this helps.

kondaur [170]

Answer:

Null hypothesis: $p_1 -p_2 =0$ ,

Alternative hypothesis: $p_1 -p_2 > 0$

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Solution to the problem

Some Notation

$p_1$ represent the proportion of the news media that is Democrat

$p_2$ represent the proportion of the public that is Democrat

On this case the claim that they want to test is: "That a larger proportion of members of the news media are Democrats when compared to the general public". So we want to check if the population proportion p1 is higher than p2, so this needs to be on the alternative hypothesis and on the null hypothesis we need to have the complement of the alternative hypothesis.

Null hypothesis: $p_1 \leq p_2$
