Answer:

a) 10c =60

c = 6 chairs per table

b) 60 - 18 = 42 chairs

Answer:

60= -(8tb-2c)-(2ta-c)

Step-by-step explanation:

A table has 4 sides since they are rectangles let's assume that two sides can fit 2 chairs and two sides can fit 1. That's 6 total, now if you put ten end to end, eight tables ends are completely cover (16 chairs are taken out of the equation), then the end tables have one end covered on each side (-2). There are now 18 chairs gone. He can only fit (60-18= 42) 42 chairs on the tables.

Consider a multiple choice exam with 10 questions, and with 4 possible answers to each question (labeled A, B, C, and D). 1a. Wh
mrs_skeptik [129]

Answer:

(1a) 9.54e-07 (1b) 0.9437 (2) 10^8

Step-by-step explanation:

We have n = 10 questions. For each question in the multiple choice exam, we can choose the correct answer with probability p = 0.25 or an incorrect answer with probability q = 0.75 (just by guessing). Besides is reasonable to believe that questions are independent. Let X be the random variable that represents the number of correct answers (just by guessing) observed during the n = 10 questions, so, X have a binomial distribution.

(a) The probability of getting a perfect score just by guessing is

P(X = 10) = 10C10(0.25)^{10}(0.75)^{10-10} = 9.54e-07

(b) The probability of getting at least one question correct, just by guessing

P(X\geq1) = \sum_{x=1}^{x=10}10Cx(0.25)^{x}(0.75)^{(10-x)} = 0.9437

2. Each RUID is 9-digits long, there are 10 digits, each of the nine positions for a digit of the RUID has 10 posibilities except the 4th and 5th positions which must be both 0. For the multiplication rule there can be (10)^3(1)(1)(10)^5 = 10^8 different RUIDS.

When Kimchi is made, it is initially fermented for the first 3 days at a temperature of 70 degrees Fahrenheit and then immediate
svet-max [94.6K]

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

\begin{cases}f(x) = 70^{\circ }  & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}

  • Please find attached the graph of the step function?

<h3>How can the step function be written?</h3>

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

\begin{cases}f(x) = 70^{\circ }  & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}

The graph of the above function created with MS Excel is attached
