First we have to see the formula of profit, which is
And it is given that profit should be atleast $150, that is
Let Ritax dollars per cake, so for 15 cakes, she charge 15x .
And she epent 30 dollars for 15 cakes.
So we will get
Adding 30 to both sides
Correct option is the second option .
Hi friend,
Converting mixed numbers to fractions<span>, our initial equation becomes,
</span>
11/4 x 11/6
Applying the fractions formula for multiplication<span>,
</span>
11 x 11 --> 121
-----
4 x 6 ------> 24
Simplifying 121/24<span>, the answer is:</span>
5 1/24
Hope this helped
Its an acute triangle by angles.
Its a NONE by sides.
The postulate of the corresponding angles establishes that when a transversal line cuts two parallel lines, the corresponding angles are congruent. These angles are on the same side of the parallel lines and on the same side of the transversal line.
Then, if we based on this definition and analize the figure attached, we can notice that the angles ∠1 and ∠3 are corresponding angles, so they are congruent. In this case the angle ∠1 is internal and the angle ∠3 is external.
The answer is: ∠1 and ∠3 are congruent (See the image attached).
Answer:
The t distribution is used, because we have the standard deviation for the sample.
Step-by-step explanation:
When to use the z or the t distribution?
When we have the standard deviation for the population, we use the z distribution.
When we have the standard deviation for the sample, we use the t distribution.
In this question:
We have the standard deviation for the sample, which means that the t distribution is used.
