Answer:

Takeru bought 72 eggs and baked  18 soufflés .

Step-by-step explanation:

Let

e = number of eggs Takeru bought.

s = number of soufflés Takeru bought.

Then we know that Takeru  bought 4 times as many eggs as he baked soufflés, therefore:

e=4s.

And since for every soufflés Takeru bakes he uses 3 eggs, and after backing he has 18 eggs left, we have:

e-3s=18 <em>This says that from e eggs there are 18 eggs left after Tkeru used three eggs for each soufflé.</em>

Now we have two equations:

(1).e=4s.

(2).e-3s=18

We put the value of e from equation (1) into equation (2) and solve for s and get:

s=18

e=4s=4*18=72.

Thus

Number of eggs Takeru bought = 72.

Number of soufflés Takeru bought = 18.

Write a statement that correctly interprets the confidence interval. Choose the correct answer below. A. One has 90​% confidence
poizon [28]

Answer:

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

Step-by-step explanation:

A. <em>One has 90​% confidence that the sample proportion is equal to the population proportion. </em>

Confidence interval gives an interval estimate, not an equality

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

<em>Ture. </em>

<em>C.</em><em> One has 90​% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>

Also true but <em>One has 90​% confidence is not good interpretation. </em>

<em>D</em><em>. 90​% of sample proportions will fall between the lower bound and the upper bound.</em>

<em>Lower bound and upper bound is given to estimate population proportion. </em>

Determine the perimeter of the triangle.<br> 3x<br> x + 6<br> 5x – 7
Gekata [30.6K]

Answer:

9x-1

Step-by-step explanation:

The perimeter of the triangle is adding up all 3 sides.

(3x)+(x+6)+(5x-7)=P

9x-1 = perimeter

All I have done is combine like terms.

If there is a... x = something, replace x with the number.
