Answer:

The term 27p represents the total cost in dollars of pants

The term 13(p+4) represents the total cost in dollars of shirts

The expression 27p+13(p+4) represents the overall cost in dollars of the shirts and pants Christ buys

Step-by-step explanation:

Disclaimer: if the owner can include the options, I can give a better answer.

We know each pair of pants is $27. Since each pair of pants costs $27, we can say the total cost in dollars of pants is equal to 27*P. For each pair of pants Chris buys, he buys 4 shirts. P+4 is the total number of shirts Chris will buy. The price of these shirts in dollars is $13. So we can assume the total cost in dollars of shirts will be 13(P+4). The total expression is the total amount in dollars Chris spends.

Answer: 239,306 total registered doctors

Step-by-step explanation:

1. Form the ratio of amount of female doctors(41,400) to total amount of doctors(x) and compare it to percent of female doctors in the field(17.3) to total percent of doctors(100).

[tex]\frac{41400}{x}=\frac{17.3}{100}[/tex]

2. Cross Multiply the amount of female doctors(41,400) to the total percent of doctors(100) so that it stays equal to the percent of female doctors(17.3) to the amount of doctors(x).

[tex]41400*100 = 17.3x[/tex]

3. Simplify

        [tex]\frac{414*10^{4} }{17.3} = \frac{17.3x}{17.3}[/tex]

For given relations, relation (1) and relation (3) represent y as a function of x.

And relation (2) does not represent y as a function of x.

In this question, we have been given some relations.

We need to determine which relations represent y as a function of x.

We know that a relation is function when there is unique output for each input.

Consider the first relation.

y = -3.4x

For each value of x there's unique and distinct output. Here x can take any real value.

so, the above relation is a function.

Consider the second relation.

We can observe that, for x = 1 there are two outputs i.e., y = 1 and y = -1.

Similarly for x = 4, there are two outputs y = 2 and y = -2.

this means, the second relation is not a function.

Now, consider the last relation.

From this graph we can see that from x = -∞ to x = ∞, there are unique outputs.

So, above graph represents a function.

Also, by vertical line test, the graph represents a function.

Therefore, for given relations, relation (1) and relation (3) represent y as a function of x.

And relation (2) does not represent y as a function of x.

Numbers without fractions are referred to as "whole numbers," and they are made up of positive integers and zero. It is denoted by the letter "W," and its corresponding set of numbers are 0, 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12,..

A mathematical procedure called addition symbolizes adding objects t to a larger collection. The plus sign ( + ) is used to denote it.

Some examples of the addition of whole numbers is:

1 + 8 = 9

10 + 19 = 29

A mathematical operation known as subtraction symbolizes the process of determining the difference between two numbers or units. The negative sign is used to denote it ( - ).

An example of subtraction of whole numbers is:

10 - 2 = 8

Answer:

70.42 kilometers.

Step-by-step explanation:

43 minutes/60 minutes (1 hour is 60 minutes) = 0.71 hours.

Now we set up a problem here.

50 kilometers/0.71 hours = x kilometers/1 hour

We multiply out 1 hour and cancel out from both sides.

50/0.71 kilometers = 70.42 kilometers.

Therefore, the train was traveling at 70.42 kilometers per hour.

The probability value indicates that there is statistical significance in 0.0345 option (a) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

As we know,

Statistical significance is commonly defined as a probability value of 0.05 or even less. P-value can be used in replacement of or in addition to preset levels of confidence when testing the claim.

The value 0.0345 < 0.05

The probability value of 0.0345 indicates that there is statistical significance

Thus, the probability value indicates that there is statistical significance in 0.0345 option (a) is correct.

After multiplying 0, 3 times and following the laws of exponents, the value yielded is 0.

What is the law of exponents?

When multiplying a number by itself constantly, exponents are employed to illustrate this. For the case, 73 can be used to represent 7 x 7 x 7. The exponent, in this case, is" 3," denoting how numerous times the number 7 has been multiplied. Then, the number that's actually being multiplied is 7, which serves as the base.

Given that,

Answer:

$1.20

Step-by-step explanation:

if the donuts normally cost 12 dollars, but they are on on sale for 10% off, then all you have to do is divide 12 by 10.

12 ÷ 10 = 1.2

since we are working with money, we need to add a 0 at the end to make it 1.20, since you need 100 cents to make a dollar.

another way you could write the equation is,

10% × 12 = 1.2

1.2 = 1.20

hence, the sale price for the donuts is $1.20
