The function rule for the total cost of the cookbook is C(x) = 750 + 25x, where x is the number of copies ordered.

# of Copies Ordered Total Cost

100 875

200 1000

300 1125

400 1250

If 400 copies are ordered instead of 100, the total cost would be $1250 instead of $875, saving $375 per book.

The soda still left in the bottle is given as 4 liters in 2-liter bottle.

As mentioned, Sergio poured 4/5 of the soda from a 2-liter bottle for his guests.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
The soda left in the bottle will be the difference of the total quantity and the quality of the soda poured. So,
= 20 - 4/5 × 20
= 20 - 16
= 4

Thus, the soda still left in the bottle is given as 4 liters of a 2-liter bottle.

the perimeter of a triangle is 49 feet. The triangle's one side is seven feet shorter than its other. the length of each side , Second side: 16 feet, First side: 9 feet,Third side: 12 feet

To find the length of each side of the triangle, we need to start by looking at the perimeter, which is 49 feet.

Perimeter = 49 feet

Second side = 49 - 4 = 45 feet

First side = 45 - 7 = 38 feet

Third side = 45 + 4 = 49 feet

We know that the third side is 4 feet shorter than the second side, so we can subtract 4 feet from the perimeter to find the length of the second side, which is 16 feet. Then, we know that the first side is 7 feet shorter than the second side, so if we subtract 7 feet from the second side we can find the length of the first side, which is 9 feet. Finally, to find the length of the third side, we add 4 feet to the second side, which gives us 12 feet. Therefore, the length of each side of the triangle is 9 feet, 16 feet, and 12 feet.

The rate of interest for simple compounding if Louis is offered an interest rate of 6.35% for an investment with continuous compounding, is 0.0515 or 5.15%, so option B is correct.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Eva is offered an interest rate of 5.28% for her savings with simple compounding,

Here, P will be the same, the amount will be the same and the time will be the same,

The amount in simple compounding = The amount in continuous compounding

[tex]p(1 + r)^t = pe^{Rt}[/tex]

Here, R is the rate of interest for simple compounding,

Step-by-step explanation:

1) Subtract the two numbers.

2.07 - 0.69 = 1.38

2) Divide the difference of the subtraction problem by 2.07, the value of the marked up cards.

1.38/2.07 = 2/3

3) Because percent means divided by 100, multiply 2/3 (0.6666...) multiplied by 100 as a fraction because x/100 x 100 = x.

Answer:

  -25/(12π) ft/min ≈ -0.663 ft/min

Step-by-step explanation:

You want the rate of change of height of the salt in a cone with height 5 ft and diameter 4 ft, filled 3 ft up from the vertex, and decreasing in volume at the rate of 3 cubic feet per minute.

The rate of change of height is the rate of change of volume, divided by the surface area.

The given cone dimensions tell you the radius is 2/5 of the height of the cone, so the radius of the surface when it is filled to a depth of 3 ft is ...

  r = (2/5)(3 ft) = 1.2 ft

The area of the surface is the area of a circle with this radius:

  A = πr² = π(1.2 ft)² = 1.44π ft²

Then the rate of change of height is ...

  h' = V'/A

  h' = (-3 ft³/min)/(1.44π ft²) = -25/(12π) ft/min ≈ -0.663 ft/min

The 3 : 7 ratio into which the amount of money is shared by Moira and Non where Non gets $28 more than Moira, indicates;

a) The total amount of money they share is $70

b) The amount Moira gets is $21, while the amount Non gets is 3 : 7

A ratio is a quantitative expression that specifies the number of times a value is contained within another value.

The ratio by which Moira and Non share the money = 3 : 7

The amount Non gets = 28 + The amount Moira gets

Let x represent the amount Moira gets, therefore;

The amount Non gets = 28 + x

The specified ratio indicates;

[tex]\dfrac{x}{28 + x} = \dfrac{3}{7}[/tex]

7·x = 3 × (28 + x)

7·x = 84 + 3·x

7·x - 3·x = 84

4·x = 84

x = 84 ÷ 4 = 21

x = 21

The total amount of money = The amount Moira gets + The amount Non gets

Therefore; The total amount of money = x + 28 + x = 2·x + 28

2·x + 28 = 2 × 21 + 28 = 70

The total amount of money = $70

b) The amount of money Moira gets, x = $21

The amount of money Non gets = $28 + $21 = $49

Take a six-sided dice for example.

Write about p (ac).

A six-sided die will obviously be rolled.

Obtaining a number fewer than three is required for letter A.The initials "AC" stand for "Anything which is not in A" on a die or "A-Complement".

A = 3 can be used to calculate a number less than 3 or a number greater than 3.

Taking into account that the possibilities 1, 2, 4, 5, and 6 are all in AC.

If we take the ratio of successful outcomes to overall outcomes, we have a chance.

P(AC) = 4/6 = 2/3

Step-by-step explanation:

We can find the slope of the second line using the formula

[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the second line and m1 is the slope of the first.

Thus, since 1/9 is the slope of the first line, we have

[tex]m_{2}=-\frac{1}{(1/9)} \\m_{2}=-9[/tex]

Since the slope intercept form is y = mx + b, where b is the y-intercept, we need to it in the second line by plugging in (3, 4) for x and y and -9 for m:

[tex]4=-9(3)+b\\4=-27+b\\31=b[/tex]

A t-test cannot cover more than one group. This has to do with the underlying method used to calculate the test value.

Explain about t-test?

The t-test is designed to compare the means of two populations based on the means of the two samples. (any sample from either population).

The most important observation is that the t-test computes the difference between two sample means.

If you have trouble understanding 'variance', you can use the word standard deviation from the previous text to get your points.

In other words, there is more than one difference between the groups, but we want one measure of Total Difference Between Groups. The t-test cannot do that.

So the procedure for groups of three or more is: Run ANOVA first. As a second step, if you have reason to believe that differences exist (based on this test), you can use the t-test to determine where those differences lie.

A t-test cannot cover more than one group. This has to do with the underlying method used to calculate the test value.
