Answer:

5 shirts

Step-by-step explanation:

we can use the problem to get an equation:

65+15x=50+20x

subtract 50 from each side to get:

15+15x=20x

subtract 15x from each side to get:

15=5x

divide each side by 5 to get your answer:

x=5

It costs the school band SS dollars per sandwich that they make. The band sells each sandwich for 20\%20% more than it costs to
Annette [7]

Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar

Selling Price of 1 Sandwich = 20 % more than Cost Price S

                    = S + 20 % of S

                     = \frac{20S}{100}+S=\frac{120S}{100}

                     =$ 1.20 S

                      = $(S + 0.20 S)

Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)

The expression $73(S+0.2 S) →→  Selling Price of 73 Sandwiches

dimaraw [331]

Arithmetic sequence

Explanation

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence

Step 1

Let

\begin{gathered} a_1=5 \\ a_2=7 \\ a_3=9 \\ a_4=11 \end{gathered}\begin{gathered} a_2-a_1=7-5=2 \\ a_3-a_2=9-7=2 \\ a_4-a_3=11-9=2 \end{gathered}

so, the difference is always the same, 2

Hence, the answer is a Arithmetic sequence

If one wanted to find the probability of ten customer arrivals in an hour at a service station, one would generally use the ____
lbvjy [14]

If one wanted to find the probability of ten customer arrivals in an hour at a service station, one would generally use the Poisson probability distribution.

How do you find the probability of success for each trial?

  • Each trial has a head (success) and a tail (failure) outcome (failure). Each trial's chances of success are p = 1/2 and its chances of failure are q = 1 1/2 = 1/2.
  • The variable X, which counts the number of successes across 12 trials, is the one that interests us. This is an illustration of a 12-trial Bernoulli experiment.

What is the probability formula?

Probability is equal to the number of favorable outcomes (Total number of outcomes) P = n (E) / n (S) E is the event, P is the probability, and S is the sample area.
