To calculate a decimal multiplier to decrease a quantity by a certain percentage, subtract the percentage you want to decrease by from 100% and then convert to a decimal. For a 3.4% decrease, the decimal multiplier is 0.966.

The decimal multiplier to decrease a quantity by 3.4% can be calculated by subtracting the percentage decrease from 100%, then converting into decimal form. Therefore, 100% - 3.4% gives us a remainder of 96.6%. This is the amount we want to remain after the decrease. Convert this to a decimal multiplier by dividing by 100, i.e., 96.6% ÷ 100 = 0.966. Thus, the decimal multiplier to decrease by 3.4% is 0.966.

Answer: They won 22 gold, 18 silver and 12 bronze.

Step-by-step explanation: Suppose gold is g, silver is s and bronze is b.

The number of silver was 6 less than twice of bronze: s = 2b - 6

Gold was 4 more than silver: g = s + 4

Total is 52: g + s + b = 52

We have 3 equations and 3 variables. To determine each one:

s = 2b - 6 (1)

g = s + 4 (2)

g + s + b =52 (3)

Substitute (1) in (2):

g = 4 + 2b - 6

g = 2b - 2 (4)

Using (1) and (4), substitute in (3)

2b - 2 +2b - 6 + b = 52

5b = 52+8

b= [tex]\frac{60}{5}[/tex]

b = 12

With b, we find s:

s = 2.12 - 6

s = 18

With s, we find g:

g = 4 + 18

g = 22

Therefore, the team won 22 gold, 18 silver and 12 bronze.

Answer:

Gold : 22 medals , Silver : 18 medals, Bronze : 12 medals

Step-by-step explanation:

Solution:-

- Denote the total number of medals won by USA, T = 52

- The number of bronze medals = x

- The number of silver medals = y

- The number of gold medals = z

- We are given that number of silver medals (y) was 6 ​fewer (less)​ than twice the number of bronze medals (x). So the mathematical representation of this observation would be:

                                  y = 2x - 6  

- Similarly, the number of gold medals (z) was ​four more than​ the number of silver medals (y).  So the mathematical representation of this observation would be:

                                 z = y + 4

- The total number of medals T:

                                T = x + y + z

- We have 3 equations and 3 unknowns. Solve the equations simultaneously,

                                z = 2x - 6 + 4 = 2x - 2

                                T = x + ( 2x - 6 ) + ( 2x - 2)

                                52 = 5x - 8

                                5x = 60

                                x = 12 bronze medals

                                z = 2x - 2

                                z = 2*12 - 2

                                z = 22 gold medals

                                z = y + 4

                               y = 22 - 4

                               y = 18 silver medals

Answer:

n = 192

Step-by-step explanation:

The volume of a cube is given by the formula;

V = L³

where L = cube side

Given L as 1/4, the equation become;

V = (1/4)³

V = 1³/4³

V = 1/64

But volume of n cube = volume of rectangular prism

Therefore,

n * 1/64 = 3

n = 64 * 3

n = 192

Therefore, 192 units is needed.

Answer:

Thursday.

Step-by-step explanation:

We have that the first day of Alex's trip was a Monday, that is to say that the next Monday will be obtained by adding 7 to the previous numbers.

1 + 7 = 8

8 + 7 = 15

15 + 7 = 22

22 + 7 = 29

29 + 7 = 36

We have that the 36th is a Monday, therefore:

37, Tuesday

38, Wednesday

39, Thursday

In other words, the 39th would be Thursday.

The value of [tex]\(10^2 - 4^3\)[/tex] is [tex]\(6^2\)[/tex], equivalent to 36.

To solve this expression, first, let's calculate each part:

[tex]$10^2 = 10 \times 10 = 100$[/tex]

[tex]$4^3 = 4 \times 4 \times 4 = 64$[/tex]

Now, we can substitute these values into the expression:

[tex]$10^2 - 4^3 = 100 - 64 = 36$[/tex]

Now, we need to express 36 as a power of 6. We can see that [tex]$36 = 6^2$[/tex], so:

[tex]$36 = 6^2$[/tex]

Therefore, the value of [tex]$10^2 - 4^3$[/tex] as a power of 6 is [tex]$6^2$[/tex]

Answer:

The weigth of the three heavy balls is 35.1 pounds.

Step-by-step explanation:

In order to solve this problem we will call the weigth of the light ball by "l" and the weigth of the heavy ball by "h". The total weigth of the six balls is 52.65 pounds, so we have:

3*l + 3*h = 52.65

We know that the weigth of the heavy ball is twice the weight of the light ball, so we have:

h = 2*l

We can use this value on the equation to solve for "l". We have:

3*l + 3*(2*l) = 52.65

3*l + 6*l = 52.65

9*l = 52.65

l = 52.65/9 = 5.85 pounds

h = 2*l = 2*5.85 = 11.7 pounds

3*h = 35.1 pounds

The weigth of the three heavy balls is 35.1 pounds.

Final answer:

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is approximately 11.7 pounds.

Explanation:

The total weight of the 6 bowling balls is 52.65 pounds. Let's represent the weight of a light bowling ball as x pounds. Since the weight of a heavy bowling ball is twice that of a light bowling ball, the weight of a heavy bowling ball is 2x pounds. So we can set up the equation:

3x + 3(2x) = 52.65

Simplify and solve for x:

3x + 6x = 52.65

9x = 52.65

x = 52.65/9

x = 5.85

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is twice that, which is approximately 11.7 pounds.

Step-by-step explanation:

The way to check if a graph is a function is by the vertical line test.

If, anywhere on the graph, a vertical line passes through the graph at more than one point then it is NOT a function.

So we see that the graph on the top left is not a function because we can draw a vertical line through the diamond shaped graph which pass through the graph at 2 points.

The same applies to graph 2:- its not a function for the same reason.

However Graph 6 is a function because any vertical line drawn will only pass through the graph at one point.

Graph 3 is a function  for the same reason.

Graph  4 is not a function because a vertical line passes through the 2 dots on the right.

What about Graph 5?

Answer:

  x = -b/(2a)

Step-by-step explanation:

Using the power rule for derivatives, you can find ...

  f'(x) = 2ax +b

Solving for x when f'(x) = 0, we have ...

  2ax +b = 0

  2ax = -b

  x = -b/(2a)

The critical value is x = -b/(2a).

Answer:

6

Step-by-step explanation:

By the diagram you can see that the upper quartile is 6. Also this answer was calculated and checked!

If  a number line goes from 0 to 10, the whiskers range from 2 to 8, and the box ranges from 3 to 6. a line divides the box at 5 then the upper quartile of the data is 5.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We can see that the box ranges from 3 to 6, and the line inside the box divides it at 5.

Therefore, the upper half of the box represents the data between 5 and 6.

The whisker extends from the upper boundary of the box (6) to a value of 8.

Since the whisker represents the range of data within 1.5 times the interquartile range (IQR), we can calculate the IQR as follows:

IQR = Q₃ - Q₁

where Q₁ is the lower quartile and Q₃ is the upper quartile.

We know that the lower boundary of the box (Q₁) is 3.

IQR = Q₃ - 3

Also, we know that the whisker extends to a value of 8, which is 1.5 times the IQR. Therefore,

8 =  Q₃ + 1.5(IQR)

8 =  Q₃ + 1.5(Q3 - 3)

8 = 2.5 Q₃- 4.5

12.5 = 2.5 Q₃

Q₃ = 5

Therefore, the upper quartile of the data is 5.

= 9π unit squared

Maria draws a circle with double the area of circle G. This will be:

2 × 9π

= 18π2

= 18pi unit squared

Answer:

18*pi units squared.

Step-by-step explanation:

The area of a circle can be calculated with the following formula:

Area = pi * r^2

Where r is the radius.

The circle G have a radius of 3 units, so its area is:

Area1 = pi * r^2 = pi * 3^2 = 9*pi

Answer:

i believe it to be 16. Im not sure though

Step-by-step explanation:

The area of a circle is calculated using the formula A = πr^2. When the diameter is 4, the area is 4π square units.

The area of a circle, A, can be calculated using the formula A = πr2, where r is the radius of the circle. The diameter, d, is twice the radius, so we can write the formula as A = π(d/2)2. When the diameter is 4, we can substitute d = 4 into the formula and calculate the area.

A = π(4/2)2 = π(2)2 = π(4) = 4π

So, the area of a circle with a diameter of 4 is 4π square units.

Convenience sampling is a kind of non-probability sampling, i.e. all items does not have an equivalent chance or probability of being selected. This type of sampling method does not comprises of random collection of items.

Convenience sampling is where we take in items which are easy to reach or collect.

For example, sampling the the students of your own class or collecting sample from your own neighborhood.

In this case the Chief Financial Officer of Harrison Haulers, Inc. asks her staff to inspect the last 200 vouchers of the 2500 payroll vouchers that have been issued since January 1, 2000.

She did so because her staff did not have that much time in hand and it is quite convenient to check the last 200 vouchers.

This is because it is quite easy to review the last 200 payroll vouchers since they would be the most recent ones and quite easily accessible.

So, the sampling method used by the Chief Financial Officer of Harrison Haulers, Inc. is Convenience sampling.

Thus, the correct option is (C).

Final answer:
