Answer:

Option B.

Step-by-step explanation:

Given information: Circle G is inscribed with triangle EFD, arcED=104°.

We need to find the measure of arc ECF.

Draw a diagram by the given information.

Arc(ED)=104^{\circ}              (Given)

Arc(FD)=2(\angle E)=2(79)=158^{\circ}            (Central angle theorem)

Arc(ECF)=360-Arc(ED)-Arc(FD)

Arc(ECF)=360-104-158

Arc(ECF)=98^{\circ}

The measure of arc EDF is 98°.

Therefore, the correct option is B.

Let the null hypothesis be that the agent's claim is correct. Using a standard normal probability table we find:
p-value=P(Z \ \textgreater \ 1.1)=0.14
The p-value 0.14 is much larger than alpha = 0.01, so we cannot reject the agent's claim.

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that
avanturin [10]

Answer:

5 video games.

Step-by-step explanation:

In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.

120 - 68 = 52

Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.

52 / 10 = 5.2

Finally, we can see that she can afford to only buy 5 video games.

Heidi wants to make some biscuits using this recipe.
Andre45 [30]

The most cookies Heidy can make is 36 cookies.

<h3>How to calculate how many cookies can Heidy make?</h3>

To know how many cookies Heidy can make, you have to take into account the following information:

12 cookies need the following ingredients:

  • 125g butter
  • 200g flour
  • 50g sugar

In the case in which Heidy has more ingredients, we must carry out the following operations:

Divide the quantities, in the reference quantity we have:

  • 500g of butter ÷ 125g of butter = 4
  • 700g flour ÷ 200g flour = 3.5
  • 250g of sugar ÷ 50g of sugar = 5

According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.

So the number of cookies Heidy can make are:

12 × 3.5 = 42
