6 is the least significant

Answer:

See below

Step-by-step explanation:

If you consider an open circle, it would exclude the value with which we have circled when writing the inequality. Hence the only possible signs with in such an example can be a greater than sign ( > ) or less than sign ( < );

Let us take a look at an example to help. We are given a graph with an open circle on the number say 3. An arrow extends to the right of this number 3;

Answer:

x - 5

Step-by-step explanation:

Again, we can just write the width as (x² - 25) / (x + 5) which will be x - 5.

Answer:

area = length x width

x² - 25 = x + 5 · width

(x - 5)(x + 5) = (x + 5)w

(x - 5)(x + 5) / (x + 5) = (x + 5)w / (x + 5)

x - 5 = w

Step-by-step explanation:

1. write down the formula of area.

2. since the area is a difference of squares, factor them into two binomials, and replace the length by its measure. you can use w for width

3. to get width, divide the one of the binomials with the length that matches together to get w.

Answer:

Option A

Step-by-step explanation:

I used a graphing tool to graph the equations given. When graphed, the lines intercept at (-2,3). Therefore, it is the solution to the system of equations. See the picture attached for the graph.

Option A should be the correct answer.

Slope of AB = 7-5/9-4

=2/5

Answer:

The median of Group A is less than that of Group B.

Step-by-step explanation:

Assume that your box-and-whisker plots look like those below.

1. Compare medians

Group A = 79

Group B = 79.5

The median of Group A is less than that of B

Correct.

2. Compare ranges

Group A: 82 - 76 = 6

Group B: 81 - 76 = 5

The range of Group A is greater than that of Group B.

Option B is wrong.

3. Compare Q1s

Group A: 78

Group B: 77

Q1 for Group A is less than that for Group B.

Option C is wrong.

Answer:

250 cards

Step-by-step explanation:

Let the number of baseball cards he originally had be x.

He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:

x - (20/100 * x) = x - 0.2x = 0.8x

During week two he bought 20% more cards than he had after week one. This means that after week two, he had:

0.8x + (20/100 * 0.8x)

= 0.8x + (0.2 * 0.8x)

= 0.8x + 0.16x = 0.96x

He now has 10 fewer cards. This means that:

x - 10 = 0.96x

Collecting like terms:

x - 0.96x = 10

0.04x = 10

=> x = 10/0.04 = 250

He had 250 cards originally.

Answer:

0.18

Step-by-step explanation:

Given: 60% students were in high school, 40% were in middle school and of the high school students, 30% had visited a foreign country

To find: probability that the student is in high school and has visited a foreign country

Solution:

Let x denotes total number of students

Number of students in high school = 60% of x = [tex]\frac{60}{100}x[/tex]

Number of students in middle school = 40% of x = [tex]\frac{40}{100}x[/tex]

Number of students who are in high school and have visited foreign country =  30% of Number of students in high school = [tex]\frac{30}{100}(\frac{60}{100})x=\frac{18}{100}x[/tex]

Probability that the student is in high school and has visited a foreign country = Number of students who are in high school and have visited foreign country/ Total number of students = [tex]\frac{\frac{18}{100}x}{x}=\frac{18}{100}=0.18[/tex]

Answer: each soda costs $1.5 and each hotdog costs $3.

Step-by-step explanation:

If H is the price for one hotdog and S is the price for one soda, we have the equations:

for Jack.

3*H + 2*S = $12

For Angie.

1*H + 4*S = $9

Now we can isolate one of the variables in one of the equations and then replace it in the other equation, let's isolate H in the second equation:

H = $9 - 4*S

now we replace it in the first eq

3*H + 2*S = $12

3*($9 - 4*S) + 2*S = $12

$27 - 12*S + 2*S = $12

-10*S = $12 - $27 = -$15

S = $15/10 = $1.5

Now we can replace it in the equation for H and get:

H = $9 - 4*$1.5 = $3

So each soda costs $1.5 and each hotdog costs $3.

Answer: One hotdog cost $3 and One soda costs $1.5

Step-by-step explanation:

Let hotdogs be denoted by h

Let sodas be denoted as s

Jack bought 3 hotdogs and 2 sodas for a total of $12. This can be written as:

3h + 2s = 12

Angie bought 1 hotdog and 4 sodas for $9. This can be written as:

h + 4s = 9

3h + 2s = 12

h + 4s = 9

1 × (3h + 2s = 12)

3 × (h + 4s = 9)

3h + 2s = 12

3h + 12s = 27

Subtract the equation

-10s = -15

s = -15/-10

s = 1.5

One soda cost $1.5

Since h + 4s = 9

h + 4(1.5) = 9

h = 9 - 6

h = 3

One hotdog costs $3

Answer:

   quotient: 5x^4 -15x^3 +45x^2

Step-by-step explanation:

The division is performed in the attachment. At each stage, the quotient is the ratio of the highest-degree terms in dividend and divisor.

To find the dividend for the next step, subtract the product of quotient term and divisor from the current dividend. This is essentially the same way you do long division using integers.

Answer:

x = - 1

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

y = - 2x² - 4x - 11 ← is in standard form

with a = - 2 and b = - 4 , thus

x = - [tex]\frac{-4}{-4}[/tex] = - 1

x = - 1 is the equation of the axis of symmetry

63+ KJL = 180

Subtract 63 from each side

63+ KJL - 63 = 180-63

JKL = 117

Answer:

Type 7.5 in the box!

Step-by-step explanation:

Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;

[tex]Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units[/tex]

Area = 7.5 square units

The area of the trapezoid is 7.5 square units.

The length of base 2 = 4 units.

The length of height = 3 units.

The area of the trapezoid

= (Average of the two bases) × Height

Putting all the values in the above formula, we get

The area of the trapezoid

= {(1 + 4)/2} × 3

= 7.5 square units.

Hence, the area of the trapezoid is 7.5 square units.

Answer:

[tex]g(x)=-5\cos (2x)[/tex]

Step-by-step explanation:

The given function is

[tex]f(x)=5\cos (2x)[/tex]

If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

[tex]P(x,y)\Rightarrow P'(x,-y)[/tex]

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is

[tex]g(x)=-f(x)[/tex]

Substituting the value of function f(x), we get

[tex]g(x)=-5\cos (2x)[/tex]

Therefore, the required function is [tex]g(x)=-5\cos (2x)[/tex].

There are 12 bags of apples on a market stall. The number of apples in bag 12 is 96.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

It is Given that, there are 12 bags of apples on a market stall.  

The mean number of apples in each bag is 8.  

We need to calculate the number of apples in the 12 bags.

The mean of "n" observations is given as

Mean = Sum of observations/the number of observations

8 = sum of observations/12

The total number of apples = 8 x 12 = 96

Hence, there are 96 apples in 12 bags.

Step-by-step explanation:

first work out wax used for cone using formula

1/3 x 3.14 x r squared x height

using this the total for the candle must be 113

formula for a sphere is 4/3 x 3.14 x r cubed

so we know 113 /3.14 / 4/3 = r cubed
