Evaluate |-15| + |-6|.

Answers

Answer:

21

Step-by-step explanation:

The absolute value of an expression is its distance from 0.

For example, take the number -5:

<-------|------------------|------------->

        -5                   0

It is 5 units to the left of zero, so its absolute value is 5, NOT -5 because distance is always positive, no matter the direction.

To evaluate the given expression, first find each absolute value:

[tex]|-15| = 15, \, \, \, \, \, \, |-6| = 6[/tex]

Then, simplify:

[tex]|-15| + |-6| \\ =15 + 6 \\= 21[/tex]

according to a study by the centers for disease control and prevention, about 33% of u.s. births are caesarean deliveries. suppose seven expectant mothers are randomly selected. what is the probability that at least one of the expectant mothers will have a caesarean delivery?

Answers

The probability that at least one of the expectant mothers will have a cesarean delivery is 0.9394.

What is probability?

Probability is the likelihood that something will happen. Based on the information, about 33% of u.s. births are cesarean deliveries.

The number (n) is also given as 7.

p = 33% = 0.33

n! / (n – r)!

N is the number of things you are choosing from,

r is the number of items.

P(x:n,p) = ⁿCˣ x pˣ(1-p)ⁿ⁻ˣ

n is the number of trials (occurrences)

X is the number of successful trials

p is probability of success in a single trial

ⁿCₓ is the combination of n and x

Therefore, the probability will be:

= 1 - P(no mother will have a Caesarean section)

= 1 - P(X = 0)

= 1 - ⁷C₀ (0.33)^0(0.67)^7

= 1 - 0.0606

= 0.9394

At a dinner party, each guest is to receive a bag of small gifts. How many gifts should be placed in each bag if there are 8 guests and 32 gifts altogether?

Answers

Answer:

4

Step-by-step explanation:

Total number of gifts = Sum of all gifts given to each guest

                                    = (Number of guests) * (Number of gifts per guest)

By making the number of gifts per guest the subject of the formula:

Number of gifts per guest = Total number of gifts/Number of guest

But:

Total number of gifts = 32

Number of guests = 8

Number of gifts per guest = Total number of gifts/Number of guest

                                              =32/8

                             =4

Answers

The expected value and the standard error of the sample mean derived from a random sample of 2 pizzas is 0.57

The statistic known as the sample mean is created by arithmetically averaging the values of a variable in a sample.

The sample mean is an estimator of the expected value if the sample is taken from probability distributions with a common expected value.

A plane flew 216 miles from Bristol airport to Leeds Bradford airport. It had an average speed of 162mph and arrived at 18:15. Work out what time the plane left Bristol airport. Give your answer using the 24 hour clock.

Answers

The plane left Bristol airport at 16:55.

This is a problem from time and distance. We can solve this problem by following a few steps.

We have to know the relation between time, speed, and distance. The relation is denoted as,

t = s/v; t is denoted as time interval, v is denoted as velocity or speed in this case and s is denoted as displacement or distance.

We have to find the time. Here velocity is 162 mph and the total distance between  Bristol airport to Leeds Bradford airport is 216 miles.

t = 216 miles/ 162 mph = 1.33 hour = 80 minutes.

Therefore the plane left Bristol airport is, ( 18 hours 15 minutes - 80 minutes) = 16 hour 55 minutes = 16:55

A family arrives at the Walt Disney world parking lot to get from their car in the parking lot to the gate at the magic kingdom they walk 1/4 mile take a train for 1/3 of their total distance and take a monorail for 1/2 of their total distance how far is it from their car to the gate of magic kingdom

Answers

Answer:   1.5 miles

This is equivalent to 3/2 as an improper fraction and 1 & 1/2 as a mixed number.

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

Explanation:

x = total distance in miles

The train and monorail take 1/3 and 1/2 of the total distance respectively

Add up those fractions to get

1/3 + 1/2 = 2/6 + 3/6 = 5/6

Remember that you can only add fractions when the denominators are the same.

5/6 of the total distance consists of the train and monorail.

That means the walking portion must be 1 - 5/6 = 6/6 - 5/6 = 1/6 of the total distance.

----------------------------

In short, we found that 1/6 of the total distance consists of walking.

(1/6)x = 1/4 mile

x/6 = 1/4

4x = 6*1

4x = 6

x = 6/4

x = 3/2

x = 1.5 miles is the total distance

---------------------------

Check:

1/6 of x = 1/6 of 3/2 = (1/6)*(3/2) = 3/12 = 1/4 mile walking

1/3 of x = (1/3)*(3/2) = 3/6 = 1/2 mile on the train

1/2 of x = (1/2)*(3/2) = 3/4 of a mile on the monorail

1/4 + 1/2 + 3/4 = 1/4 + 2/4 + 3/4 = 6/4 = 3/2 = 1.5 miles total

This confirms our answer.

Carmen invested her saving in fund B as $11,000.

What is termed as the investment?Investing entails allocating capital (money) to tasks or projects that are anticipated to generate a profit over time.The type of return generated is determined by the project or asset; for example, real estate can generate both rents as well as capital gains; numerous stocks pay semiannual dividends; and bonds typically pay regular interest.

For the given question;

Let 'x' be the amount invested by Carmen in fund B.

The, the amount invested in fund A is x - 5000.

The profit on fund A is 2% = 2%(x - 5000).

the profit on fund B is 5% = 5%(x).

Then, the total profit is $670.

The equation will be .

2%(x - 5000) +  5%(x) = 670

2(x - 5000)/100 +  5(x)/100 = 670

2x - 10,000 + 5x = 67,000.

Further simplifying.

7x = 67,000 + 10,000

7x = 77,0000

x = 11,000

Thus, amount invested in fund B is $11,000.

Graph the line that represents each linear equation does anyone know a 2d version I can see instead of words to explain it?

Answers

The graph of the first linear equation:

y = x + 3

Can be seen in the image at the end.

How to graph the linear equation?

Let's graph the first line, which is:

y = x + 3.

To graph it, we need to find two points on the line, to find these, we can evaluate the linear equation in two values of x.

Using x = 0 we get:

y = 0 + 3

y = 3

So we have the point (0, 3).

Using x = 1, we get:

y = 1 + 3

y = 4

So we have the point (1, 4)

Now we can graph these two points on the same coordinate axis and connect them with a line. Like in the example below.

We will have the following:

We will have that the value at the end will be $180 000.

The number of periods will be 15*12 = 180.

The interest per month is 0.05/12 = 0.0042

Now:

[tex]A=\frac{P((1+i)^n-1)}{i}_{}[/tex]

Here "A" is the value at the end, "P" will be the monthly payments, "i" the monthly interest rate and "n" the number of periods. So:

[tex]180000=\frac{P((1+0.0042)^{180}-1)}{0.0042}\Rightarrow P=\frac{180000\cdot0.0042}{((1+0.0042)^{180}-1)}[/tex]

Answers

Answer:

The population after x years will be P = 29000 + 700x

Let the population after the years be represented by P

Population of the town in 2003 = 29000

Annual increase in growth = 700

Then, the population after x years will be:

P = 29000 + 700(x)

P = 29000 + 700x

Therefore, the population will be P = 29000 + 700x.

Most helium comes either from mining minerals or as a byproduct of natural gas. Although helium is in low supply, the demand for it is quite high. It can be used for a variety of medical purposes, including the treatment of breathing problems such as asthma. Helium also has heart and nerve protective properties, and doctors are beginning to use it in surgery. Yet current laws make recycling helium unprofitable. For the sake of our health, those laws must change.Which statement would be the most appropriate in a conclusion to this argument? Why? A. These laws are unlikely to change, so we must take steps to manufacture helium on our own. This statement makes the logical leap that if we can't recycle helium, we should create it. B. Until human disease is a thing of the past, we cannot support laws that put helium supplies at risk. This restates the claim of this argument, which is that we should do everything in our power to treat human diseases. C. If there is any practical use for helium other than medicine, laws should change to protect current supplies of the gas. This sentence summarizes one of the major points of the argument, which is that helium reserves are in low supply. D. Human health depends on helium, and therefore it is necessary to change the laws that make it hard to acquire. This restates the claim of the argument and also summarizes the supporting evidence that illnesses can be treated by helium.
