Answer:

Ella got married on a Wednesday.

Step-by-step explanation:

Let's solve this problem by understanding the following:

Each week is composed by 7 days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

So 1 week = 7 days;

Because the married day was on the 9074th day of her life, we can find the number of weeks that 9074 days represent:

\frac{1 week}{7 days} * 9074 days = 1296.285714 weeks

This means that 9074 days represent 1296.285714 weeks, which can be interpreted as 1296 entire weeks and a fraction of a week (0.285714).

Now let's calculate how many days 0.285714 weeks represent:

\frac{7 days}{1 week} * 0.285714 weeks = 2 days

This means that 9074 days are actually 1296 weeks and 2 days, because Ella was born on a Monday, and because after 7 days (1 week) it is Monday again, after 1296 weeks it is Monday, but as we also calculated 2 extra days, then the married day is two days after a Monday, that is a Wednesday.

In conclusion, Ella got married on a Wednesday.

Answer:  Step 5

===================================================

Reason:

The order of operations is PEMDAS

  • P = parenthesis
  • E = exponents
  • M = multiplication
  • D = division
  • A = addition
  • S = subtraction

The multiplication and division are on the same level of precedent, and the same goes for addition and subtraction. Some math textbooks may refer to PEMDAS as BODMAS, which is basically the same thing.

Notice how division comes before addition. So we must compute the 10 \div 2 portion first before adding in step 4.

This is what steps 4 and onward should look like

2 + 10 \div 2\\\\2 + 5\\\\7

So that's why the error is in <u>step 5</u>

If there was parenthesis around the "2+10", and we had (2+10) \div 2, then step 5 given by your teacher would be correct.

Which of these situations fit the conditions for using Bernoulli​ trials? Explain. ​a) You are rolling 66 dice and need to get a
shutvik [7]

Answer:

Experiments a) and d) fit the conditions for using Bernoulli trials.

Step-by-step explanation:

A Bernoulli trial is one where the variable is random and dichotomic, that is, it only has two possible outcomes, True/Sucess/Yes/etc. or False/Failure/No/etc. Also, each experiment has the same probability of sucess than the one before and the one after, that means, they are independent. This probability can be calculated by dividing the number of sucess cases by the number of total cases.

Experiment a), where you need four 3s is a Bernoulli trial, as getting a 3 is sucess and not getting a 3 is a failure, and each roll of the dice is independent from each other.

Experiment b) is not a Bernoulli trial as they are more than 2 possible outcomes for the home state of the customer (50 in the case of the US).

Experiment c) is not a Bernoulli trial, as they will be chosen at random, but the first woman will have different chances to be chosen than the fourth one (if they are 20 people, the first one will have 1/20 and the fourth 1/17, as one can't be chosen more than one time).

Experiment d) is a Bernoulli trial, as a student either admits cheating or not, and we can assume that every response was independent from each other.

Answer:

a) reflection across the x-axis, shift 8 units left

b) vertical stretch of 2, reflection across the y-axis, shift up 1

Step-by-step explanation:

The negative sign outside the square root represents a reflection across the x-axis, and the +8 inside represents a shift 8 to the left

The 2 outside the square root represents a vertical stretch of 2, and the negative sign inside the square root represents a reflection across the y-axis. The +1 at the end represents a shift up 1
