A donut store has 11 different types of donuts. You can only buy a bag of 3 of them, where each donut has to be of a different t
MakcuM [25]

Answer:

165.

Step-by-step explanation:

Since repetition isn't allowed, there would be 11 choices for the first donut, (11 - 1) = 10 choices for the second donut, and (11 - 2) = 9 choices for the third donut. If the order in which donuts are placed in the bag matters, there would be 11 \times 10 \times 9 unique ways to choose a bag of these donuts.

In practice, donuts in the bag are mixed, and the ordering of donuts doesn't matter. The same way of counting would then count every possible mix of three donuts type 3 \times 2 \times 1 = 6 times.

For example, if a bag includes donut of type x, y, and z, the count 11 \times 10 \times 9 would include the following 3 \times 2 \times 1 arrangements:

  • xyz.
  • xzy.
  • yxz.
  • yzx.
  • zxy.
  • zyx.

Thus, when the order of donuts in the bag doesn't matter, it would be necessary to divide the count 11 \times 10 \times 9 by 3 \times 2 \times 1 = 6 to find the actual number of donut combinations:

\begin{aligned} \frac{11 \times 10 \times 9}{3 \times 2 \times 1} = 165\end{aligned}.

Using combinatorics notations, the answer to this question is the same as the number of ways to choose an unordered set of 3 objects from a set of 11 distinct objects:

\begin{aligned}\begin{pmatrix}11 \\ 3\end{pmatrix} &= \frac{11 !}{(11 - 3)! \times 3 !} \\ &= \frac{11 !}{8 ! \times 3 !} \\ &= \frac{11 \times 10 \times 9}{3 \times 2 \times 1} = 165\end{aligned}.

which equation results from isolating a radical term and squaring both sides of the equation for the equation
damaskus [11]

Answer:

D) c - 2 = 25 + c + 10√c

Step-by-step explanation:

The given equation is \sqrt{c - 2} - \sqrt{c}  = 5

\sqrt{c -2} = 5 + \sqrt{c} \\

Taking square on both sides, we get

Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.

c - 2 = 5^2 + (√c)^2 + 2(5)√c

c - 2 = 25 + c +10√c

Answer: D) c - 2 = 25 + c + 10√c

Thank you.

motikmotik

Answer:

(4) Bonnie’s bag is within the middle 95% of the simulated data supporting the company’s claim.

Step-by-step explanation:

We are being told that:

The J & B candy company claims that 45% of the candies it produces are blue, 30% are brown, and 25% are yellow.Each bag holds 65  candies.

From the simulation that was run 200 times

Given that:

The mean is 29.270 and the standard deviation is 3.936. from the diagram attached.

The mean - 2 SD = 29.270 - 2(3.936)

= 29.270 -  7.872

= 21.398,

This is less than 24, Hence, Bonnie’s bag is within the middle 95% of the simulated data supporting the company’s claim.
