Which of the following is true of the data represented by the box plot

Answer:

[tex]\huge \boxed{b=2}[/tex]

Step-by-step explanation:

[tex]5(2- b) = 0[/tex]

[tex]\sf Divide \ both \ sides \ by \ 5.[/tex]

[tex]2-b=0[/tex]

[tex]\sf Subtract \ 2 \ from \ both \ sides.[/tex]

[tex]-b=-2[/tex]

[tex]\sf Cancel \ negative \ signs.[/tex]

[tex]b=2[/tex]

Answer:

b = 2

Step-by-step explanation:

5(2-b) = 0

=> 5 x 2 - 5 x b = 0

=> 10 - 5b = 0

=> -5b = -10

=> -b = -10/5

=> -b = -2

=> b = 2

Let's check whether our answer is correct:

=> 5(2-2) = 0

=> 5 (0) = 0

=> 0 = 0

Step-by-step explanation:

tan ^2 x -sin ^2 x = tan ^2x sin ^2x

tan = sin / cos

sin ^2 x / cos ^2 x -sin ^2 x = sin ^2 x / cos ^2 x * sin^2 x

Multiply each side by cos ^2

cos ^ x (sin ^2 x / cos ^2 x -sin ^2 x) = cos ^2 x(sin ^2 x / cos ^2 x * sin ^2x)

sin ^2 x  - cos ^2 x sin ^2 x = sin ^2 x  * sin ^2x

Factor out sin ^2 x

sin ^2 x(1  - cos ^2 x) = sin ^2 x  * sin^2 x

We know that 1 - cos ^2 x = sin ^2 x

sin ^2 x(sin ^2 x) = sin ^2 x  * sin^2 x

Answer:

Population

Step-by-step explanation:

If we know the root Demos means people and graphic means picture, let's put the english terms together.

Demo graphic

People graphic

So this is going to be a "People Graphic." So we know that Countries and Continents are ruled out.

Now I just used logic to figure out whether it's population or leaders. A map showing the leaders of something would be useless, but a map showing population is useful. So I assumed that a Demographic map shows population (I also looked it up to check, and yes this is right.)

Hope this helped!

Answer:

(7, 7 )

Step-by-step explanation:

The translation rule

(x, y ) → (x + 5, y + 4 )

Means add 5 to the original x- coordinate and add 4 to the original y- coordinate, thus

(2, 3 ) → (2 + 5, 3 + 4 ) → (7, 7 )

Answer:

Step-by-step explanation:

Convert mixed fraction to improper fraction.

[tex]1\frac{5}{8}*2\frac{2}{3}=\frac{13}{8}*\frac{8}{3}\\\\\\=\frac{13}{3}\\\\\\=4\frac{1}{3}[/tex]

Answer:

4 1/3

Step-by-step explanation:

1 5/8 × 2 2/3

First we turn it into an improper fraction:

1 5/8 × 2 2/3 = 13/8 × 8/3

Now we multiply them across:

13/8 × 8/3 = 104/24

Now we simplify:

104/24 = 13/3

because 3 × 8 = 24 and 13 × 8 = 104

Now we simplify again because we can't leave it as an improper fraction. So we turn it into a mixed fraction:

13/3 = 4 1/3

4 1/3 is answer

Answer: Either the plane and the ray perfectly coincide in which case there is an infinity of solutions or the ray is away from the plane in which case there is no intersection. Generally in a C++ implementation, when the denominator is lower than a very small value, we simply return false (no intersection was found).

Answer: Commutative property of addition

This is the idea that x+y is the same as y+x

We can add any two numbers in any order we want.

Other examples:

2+3 = 5 and 3+2 = 5

7+2 = 9 and 2+7 = 9

Answer:

1 mile = 4 laps

3 miles = 12 laps

9/4 = x /1

9/4 = 2.25

he has run 2.25 miles = 9 laps

he needs to run 0.75 miles = 3 laps

Answer: 137

Step-by-step explanation:

The given expression: [tex]7x^2 +8x-7[/tex]

We need to find the value of the expression when x=4.

So we just use the substitution property and substitute the value of x= 4 in the given expression , we get

[tex]7(4)^2+8(4)-7\\\\= 7(16)+32-7\\\\= 112+25\\\\=137[/tex]

Hence, the value of the expression at x=4 is 137.

Answer:

(C)The finish line

The fact that Leslie used a dilation is where she made the mistake. A dilation either shrinks or enlarges a figure. So it made segment ST either larger or smaller to be able to fit to segment QR.

But congruent segments are always the same length. So there's no way that a dilation can be involved. Only rigid transformations of translations (aka shifting), reflections, and rotations are allowed. A dilation is not a rigid transformation.

Answer:

A

Step-by-step explanation:

took it on khan academy

Answer:

44m

Step-by-step explanation:

A = [tex]\pi[/tex]r² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

   = r²  = 49

   = r = √49

   = r = 7m

Perimeter of circle = 2[tex]\pi[/tex]r

                               = 2 * 22/7 * 7

                               = 44/7 * 7

                               = 44 m

Answer:

44m

Step-by-step explanation:

Area of circular field=154m²

Perimeter of the field=?

At first,

Area =22/7×r²

154m²= 22/7×r²

154×7/22=r²

49=r²

7×7=r²

7=r

Now,

Perimeter = 2×22/7×7

= 44m

Answer:

930 dollars

Step-by-step explanation:

Let software programs = S

Video game = V

Given that a company makes a profit of $7 per software program that is, 7S and $8 per video game that is, 8V. The company can produce at most 90 software programs and at most 80 video games per week. Since the Total production cannot exceed 120 items per week.

How many items of each kind should be produced per week in order to maximize the profit?

The to get profit P

P = 7S + 8V

Since the profit on video game is higher, we will give maximum production to video game. Therefore,

P = (30 × 7) + ( 8 × 90)

P = 210 + 720

P = 930 dollars

I may be wrong, but I believe the answer is $200.

4, 5, 6, 7, 8 and 9 are the whole numbers between 3 to 10.

Whole numbers are a set of numbers including all natural numbers and 0. They are a part of real numbers that do not include fractions, decimals, or negative numbers. Counting numbers are also considered as whole numbers.

Two given whole numbers are 3 and 10.

The number of whole numbers between 3 to 10 is

(10-3)-1=6

The whole numbers between 3 to 10 are 4, 5, 6, 7, 8, 9.

Therefore, 4, 5, 6, 7, 8 and 9 are the whole numbers between 3 to 10.

Explanation:

When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so

f(x) = -5x+9

f(-x) = -5(-x)+9 ... replace every x with -x

f(-x) = 5x+9

g(x) = 5x+9

A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).

Answer:

Answer: 3. x>-1

Step-by-step explanation:

First, the dot is a open circle, which means the sign should be (> or <)

Which only 3 and 4 fits

Second, the line is going to the right, which mean it is greater than the starting value.

So it should be x>-1

Answer:

[tex]\Huge \boxed{{9}}[/tex]

Step-by-step explanation:

Let the age of Darrell be x.

Let the age of Bryce be y.

x = y + 8

xy = 153

Substitute x = y + 8 in the second equation.

(y+8)y = 153

Solve for y.

y² + 8y = 153

Subtract 153 from both sides.

y² + 8y - 153 = 0

Factor left side.

(y-9)(y+17) = 0

Set factors equal to 0.

y - 9 = 0, y = 9

y + 17 = 0, y = -17

The value of y has to be positive, so y = 9.

Substitute y = 9 in the first equation.

x = 9 + 8

x = 17

Darrell is 17 years old.

Bryce is 9 years old.

Answer:

[tex]\huge\boxed{9\ years}[/tex]

Step-by-step explanation:

Let Darrel's Age be x and Bryce's Age be y

Condition 1:

x = 8 + y

Condition 2:

xy = 153

Put the 1st equation in the second one

(8+y)y = 153

y²+8y-153 = 0

y²+17y-9y-153 = 0

y(y+17)-9(y+17) = 0

(y-9)(y+17) = 0

Either,

y-9 = 0   OR    y+17 = 0

y = 9       OR    y = -17 [Contrary to be given, Age can never be negative]

So, y = 9

And

Bryce's Age = 9 years

Answer:

a)  08:04

b)  07:00

c)  14 minutes

Step-by-step explanation:

a)  According to the timetable, a bus that leaves at 07:54 from Hope Street will arrive at School Rock at 08:04.

b)  Since Jo needs to be at the school at 8 am, she can't arrive at a time that is past 8.  This means that the latest time to catch the bus station is 07:00.

c)  You have to subtract the time at which you reach the destination by the time at which you leave your starting time.  It takes the bus 14 minutes to travel from the bus station to School Road.

07:14 - 07:00 = 00:14
