Over the next week you want to watch a movie a day. In how many ways can this be done if you have 8 movies

Leto [7]

You can select from any of the 8 on the first day, leaving 7 to choose from on the second day, leaving 6 for the third. So, 8 x 7 x 6 x 5 x 4 x 3 x 2 or 8! That's 8factorial, so multiply those out or use a calculator to get 8! and that is your answer.

Mass (M) of space shuttle = 1.0 × 105 kg.
Altitude (r) = 200.0 km

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: To \: \: Find :}}} \\$

The force of gravity that the space shuttle experiences = ?

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Solution :}}} \\ \\$

$\purple{\maltese}\large\underline{\underline{\sf\:\: using \: formula :}} \\ \\$

$\bigstar \: \underline{ \boxed{\sf { \pink{g = \frac{G \: M}{{r }^{2} }}}}} \\ \\$

$\\ ❒\: \: \underline{\textbf {Putting values \: in \: the \: \: given \: formula :}} \\$

$\sf \implies \: g = \frac{G \: M}{{r }^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-11} × 1.0×10^5}{(2×10^5)^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}}\\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}} \\$

$\sf \implies \: g =1.6675×10^{-6-10}\\$

$\sf \implies \: g =1.6675×10^{-16}\: Newton\\\\$

$\:\:\:\:\:\:\:\qquad\rule{150pt}{2pt} \\\\$

Henceforth, the force of gravity experienced by the shuttle is 1.6675×10^N

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.
