Based on the given exchange rate, one would receive approximately TT 23.65 for $5.50.

We are given the exchange rate that $1.00 is equivalent to TT 4.30. This means that for every US dollar, you would receive 4.30 Trinidad and Tobago dollars.

To calculate the approximate amount in TT for $5.50, we need to multiply $5.50 by the exchange rate:

$5.50 * TT 4.30 / $1.00

By multiplying the dollar amount ($5.50) by the exchange rate (TT 4.30 / $1.00), we are effectively converting the currency from US dollars to Trinidad and Tobago dollars.

Calculating the multiplication:

$5.50 * TT 4.30 / $1.00 = TT (5.50 * 4.30)

Using a calculator, we find that the result of the multiplication, TT (5.50 * 4.30), is approximately TT 23.65.

The probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean  and standard deviation , the z-score of a measure X is given by:

Z = (X - mean)/S.D

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 2.8 feet and a standard deviation of 0.5 feet.

Find the probability that an individual man’s step length is less than 2.2 feet.

This is the p-value of Z when X = 2.2. So

Z = (2.2 - 2.8)/0.5

Z = 0.6/0.5 = 1.2

Z = 1.2

has a p-value of 0.10

Therefore, the probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

Answer:

0.27

Step-by-step explanation:

Since it's given that the student is dropped off by parents, we can ignore all the students who take the bus, so our total population is 0.45. So now we just take the seventh grade students, 0.12, and divide by the total students whose parents drop them off, 0.45.

0.12/0.45 = 0.266666, round up to 0.27.

Answer:

0.27

Step-by-step explanation:

Student dropped off by parents= 0.45

7th grade students dropped off by parents= 0.12

Probability= 0.12/0.45≈ 0.27

Option 2 is correct 0.27

The numeric value of the exponential expression in this problem is given by the following option:

A. 2^12.

The exponential expression for this problem is defined as follows:

8^x/2^y.

8 is the third power of 2, hence:

8 = 2^3.

When a term is elevated to two of it's powers, the powers are multiplied, hence:

(2^3)^x = 2^(3x).

Meaning that the exponential expression is then written as follows:

8^x/2^y = 2^(3x)/2^y.

When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:

2^(3x)/2^y = 2^(3x - y).

As stated in the problem, the numeric value of the expression 3x - y is given as follows:

3x - y = 12.

Hence the entire expression is simplified as follows:

2^(3x - y) = 2^12.

Meaning that the correct option is given by option A.

Sorry, don't know if that answers your question.

The required probability is given by  P(E') =4/35  .

Probability is the study of chance. It can also be defined as the ratio of the favorable outcomes to an event to the total number of outcomes of the event.

Given the total number of people in the USA = 273000000

Let E be the number of people who speak English at home.

Therefore the number of people who don't speak English at home is E'.

∴ E' = 31200000

S speak Spanish in their homes.

∴ S = 50% of 31200000 = 15600000

Now let us find the required probabilities.

We know that probability = favorable outcome ÷ total outcome

total outcome = 273000000

a) favorable outcome(E') = 31200000

P(E')=31200000/273000000

P(E') =4/35

b)favorable outcome(E) = 273000000 - 31200000 = 241800000

P(E) = 241800000/273000000

P(E)={31}/{35}

c)favorable outcome = 15600000

P(S)={15600000}/{273000000}

P(S)={2}/{35}

Therefore the required probability is given by P(E') =4/35 , \(P(E)=\frac{31}{35}\) P(E)=31/35 and P(E)=2/35and .

x = 301/56

Algebra is the branch of mathematics that deals with numbers and values which are represented with letters and symbols.

Sometimes, we do not want to mention a particular number, we can represent the number by a letter or a suitable symbol. This approach is algebraic.

For example, d + d = 2d

This is an example of an algebraic expression

Given the algebraic expression,

\(3\frac{1}{8} \div (x - 4 \frac{7}{28} ) = \frac{17}{18} + 1 \frac{5}{6} \)

Step 1:

Simplify the expression by converting the mixed numbers into improper fractions:

25/8 ÷ ( x - 119/28) = 17/18 + 11/6

Step 2: Simplify the right side of the equation

25/8 ÷( x - 119/28) = 17/18 + 33/18

25/8 ÷( x - 119/28) = 50/18

Step 3: Multiply both sides of the equation by (x - 119/28)

25/8 = 50/18 × (x - 119/28)

Step 4: Multiply both sides of the equation by (18/50)

25/8 × (18/50) = (x - 119/28)

Step 5: Simplify the left side of the equation

9/8 = (x - 119/28)

Step 6: Add 119/28 to both sides of the equation

9/8 + 119/28 = x

Step 7: Calculate the value of x:

x = 9/8 + 119/28

= 63/56 + 238/56

= 301/56

the three friends spent L.120.00, L.240.00, and L.360.00, respectively.

How to solve the problem?

Let's denote the amount that Alicia spends as "x". According to the problem statement, we know that Juan spends twice as much as Alicia, which means he spends 2x. Similarly, we know that Ana spends three times as much as Alicia, which means she spends 3x.

We also know that the three friends together have spent L.720.00. So, we can set up an equation to represent this:

x + 2x + 3x = 720

Simplifying this equation, we get:

6x = 720

Dividing both sides by 6, we get:

x = 120

So, Alicia spent L.120.00, Juan spent twice as much as Alicia, which is L.240.00, and Ana spent three times as much as Alicia, which is L.360.00.

Therefore, the three friends spent L.120.00, L.240.00, and L.360.00, respectively.
