Answer    Addition:  a + b.   The operation sign is +, and is called the plus sign.  Read a + b as "a plus b."

1)    For example, if a represents 3, and b represents 4, then a + b represents 7.

2)    Subtraction:  a − b.   The operation sign is −, and is called the minus sign.  Read a − b as "a minus b."

1)    If a represents 8, for example, and b represents 2, then a − b represents 6.

3)   Multiplication:  a · b.  Read a · b as "a times b."

The multiplication sign in algebra is a centered dot.  We do not use the multiplication cross ×, because we do not want to confuse it with the letter x.

And so if a represents 2, and b represents 5, then

a · b = 2 · 5 = 10.

"2 times 5 equals 10."

Do not confuse the centered dot -- 2·5, which in the United States means multiplication -- with the decimal point:  2.5.

However, we often omit the multiplication dot and simply write ab.  Read "a, b."  In other words, when there is no operation sign between two letters, or between a letter and a number, it always means multiplication.  2x  means  2 times r:

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

As the owner of Tony's Fresh and Hot Pizza Shop lacks creativity in offering a large menu, the best strategy for successfully competing despite this weakness is to focus on a niche and differentiate from the competition.

One possible approach could be to specialize in a specific type of pizza, such as Chicago-style deep-dish or Neapolitan-style pizza, and offer a limited but high-quality menu of toppings and flavors. This would allow Tony's to establish a reputation for excellence in a particular style of pizza, which could attract a loyal customer base.

Another strategy could be to emphasize the convenience and speed of Tony's delivery service, promoting the fact that customers can get hot, fresh pizza delivered to their door quickly. This could appeal to busy customers who prioritize convenience over a large menu selection.

Buying a franchise gourmet pizza shop with a large menu might not be a feasible option for Tony's, as it would require a significant investment and might not align with the business's strengths or values.

likelihood that the difference between the two sample proportions is smaller than 3 percentage points

To calculate the probability that two sample proportions are less than 3 percentage points apart, we need to use the sampling distribution of the difference between two sample proportions. Let p1 be the true population proportion for one group, and p2 be the true population proportion for another group. The standard deviation of the difference between two sample proportions can be calculated as:

√((p1 × (1-p1))/n1) + ((p2 × (1-p2))/n2)

where n1 and n2 are the sample sizes for the two groups. Since we do not know the true population proportions, we will use the sample proportions from the first sample as estimates. Let p1 be the sample proportion from the first sample, and p2 be the sample proportion from the second sample. Then, the standard deviation of the difference between the two sample proportions can be estimated as:

√((p1 × (1-p1))/n1) + ((p2 × (1-p2))/n2)

We are given that n1 = n2 = 500. Let's assume that p1 = p2 = p, where p is the sample proportion from the first sample. Then, the standard deviation of the difference between the two sample proportions can be estimated as:

√((p(1-p))/500) + ((p(1-p))/500)

= √(2p(1-p))/500

= √(p(1-p)/250)

Now, we want to find the probability that the two sample proportions are less than 3 percentage points apart, which means that the absolute value of the difference between the two sample proportions is less than 0.03.

|p1 - p2| < 0.03

|p1 - p| - |p2 - p| < 0.03

Since p1 - p2 = 0, we can simplify this to:

|p - p2| < 0.015

Using the standard normal distribution, we can calculate the probability that the standardized difference between p and p2 is less than 0.015:

P(|p - p2|/√(p(1-p)/250)] < 0.015/√(p(1-p)/250)

This is equivalent to finding the area under the standard normal distribution curve to the left and right of z = 0.015/√(p(1-p)/250).

However, we do not know the value of p, so we need to consider the worst-case scenario. The maximum value of p(1-p) occurs when p = 0.5, so we can use this value to get the most conservative estimate of the probability.

Using p = 0.5, we get:

P(|p - p2|/√(p(1-p)/250)] < 0.015/√(0.5 × (1-0.5)/250)

= P(|p - p2|/0.0346 < 0.015)

Using a standard normal distribution table or calculator, we can find that the probability that a standard normal variable is less than 0.015 is approximately 0.556.

Therefore, the probability that the two sample proportions are less than 3 percentage points.

Answer:

the scientist needs to mix 35 ounces of water with 105 ounces of the 20% salt solution to obtain 140 ounces of the mixture that is 15% salt.

Step-by-step explanation:

Let's call the number of ounces of water that the scientist needs to mix with the salt solution "x". Then, the number of ounces of the 20% salt solution that she needs to use would be 140 - x (because the total amount of mixture is 140 ounces).

Now, we can set up an equation based on the amount of salt in the mixture:

0.15(140) = 0.20(140 - x) + 0(x)

This equation says that the amount of salt in the final mixture (which is 15% of 140 ounces) is equal to the amount of salt in the 20% salt solution plus the amount of salt in the water (which is 0, since water contains no salt).

We can simplify and solve for x:

21 = 28 - 0.2x

0.2x = 7

x = 35

Therefore, the scientist needs to mix 35 ounces of water with 105 ounces of the 20% salt solution to obtain 140 ounces of the mixture that is 15% salt.

Answer:

Step-by-step explanation:

To find the annual rate of interest, we first need to calculate the total interest paid over the 151-day period. We can use the formula:

Interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the annual interest rate (which we are trying to find), and Time is the time period in years.

Since the loan company assumes a 360-day year, we need to convert the 151-day period into a fraction of a year:

Time = 151 / 360 = 0.4194

Now we can plug in the given values and solve for the rate:

26 = 1,129 x Rate x 0.4194

Rate = 26 / (1,129 x 0.4194) = 0.0599 or 5.99%

Therefore, the loan company charged an annual interest rate of 5.99%.

Answer:

Step-by-step explanation:

Let's call the distance of the race "d".

When Denise runs the distance of the race at a speed of 9 mph, she takes:

time = distance / speed = d / 9

Then, when she walks back the same distance at a speed of 3 mph, she takes:

time = distance / speed = d / 3

Since she has a total of 6 hours for training, the sum of these two times must be less than or equal to 6 hours:

d/9 + d/3 ≤ 6

We can simplify this inequality by multiplying both sides by the least common multiple of the denominators, which is 9:

d + 3d ≤ 54

4d ≤ 54

d ≤ 13.5

Therefore, the distance of the race must be at most 13.5 miles.

To find the time Denise should plan to spend walking back, we can use the time formula for walking back:

time = distance / speed = d / 3

Since Denise has already spent time running the distance of the race, her total training time will be:

total time = time running + time walking back

total time = d/9 + d/3

We want to find the time for walking back, so we can solve this equation for d/3:

d/3 = total time - d/9

d/3 = (9total time - d)/9

4d/9 = 9total time/9

d = 36total time/13

Now we can substitute this expression for d into the time formula for walking back:

time walking back = d/3 = (36total time/13) / 3 = 12total time/13

Therefore, Denise should plan to spend 12/13 of her total training time walking back. For example, if she plans to train for 6 hours, she should spend about 5.54 hours (or 5 hours and 32 minutes) walking back.

Answer:

To solve this problem, we need to recall the formula d = rd (distance = rates x time)

She runs at a speed of 7 mph and walks at a speed of 3 mph.

Her distance running is

d = 7tr

where tr is the time she spends running

Her distance walking is

d = 3tw

where tw is the time she spends walking

The distances are the same so

7tr = 3tw

We also know that the total time is 4 hours

tr + tw = 4

tr = 4-tw

Substitute this value of tr in the first equation

7tr = 3tw

7(4-tw) = 3tw

28-7tw = 3tw

28 = 10tw

2.8 = tw

Denise will spend 2.8 hours (2 hours, 48 minutes) walking back and 1.2 hours (1 hour, 12 minutes running.

P(1 head) + P(3 heads) + P(5 heads) = C(6,1) * (1/2)²1 * (1/2)²5 + C(6,3) * (1/2)²3 * (1/2)²3 + C(6,5) * (1/2)²5 * (1/2)²1

= 6/64 + 20/64 + 6/64

= 32/64

= 1/2

where C(6,k) is the number of ways to choose k flips out of 6.

Therefore, the answer is:

The probability of getting an odd number of heads matches with the value f. 1/2.

The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]P = 300 * 3^w[/tex]

A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay. Over time, exponential functions monitor constant growth. Examples from the actual world include radioactive decay, compound interest, and bacterial proliferation.

From the graph, we have the following ordered pairs

(1,900) and (3,8100)

An exponential function is represented as:

[tex]P = ab^w[/tex]

At the point (1,900), we have:

ab = 900

At the point (3,8100), we have:

ab³ = 8100

Divide both equations

[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]

Evaluate the quotients

b² = 9

Take the square roots of both sides

b = 3

Recall that:

ab = 900

So, we have:

3a = 900

Solve for a

a= 300

Hence, the equation is:

[tex]P = 300 * 3^w[/tex]
