Answer:

Um.. I'm assuming the orange one

Step-by-step explanation:

because ratios are fractions and decimals, and the orange line never lies on a whole number always in the middle of the units

Step-by-step explanation: 2*(l+b)=60,    2*(2*b+b);60

                2*(2b+b)=60, 4b+2b=60, 6b=60

     b=60/6=10,   width is 10inch and length is 2*10=20 inches

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

Answer: Surface Area = 2 x (5x2 + 3x2 + 5x3) = 62 centimeters

Surface area of a right rectangular prism = 2(lh + wh + lw)

Step 1: Label the Given-

Length (l) = 5cm,      Width (w) = 3cm,      Height (h) = 2cm

Step 2: Replace the given-

Surface Area = 2 x (5x2 + 3x2 + 5x3)

= 2 x (31)

Surface Area = 62 centimeters

Horus got his answer, by applying only what lays inside the parentheses. To get the right answer, Horus must multiply what they got by 2:

2 x (31) = 62 centimeters

Answer:

SA= 15+6+10+10+15+6 = 62

Step-by-step explanation:

take your top rectangle multiply length and width= 15

Take the one right below it take the 2cm, and multiply it with 3=6

after that one doe 3x5 again=15

Then, 3x2=6

And then 5x2=10

And then once more=10

Answer:

y =  -\(\frac{1}{2}\)x + 10

Step-by-step explanation:

To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:

first write the equation 2x - y = 4 in a standard form

we will find the slope of our equation using this equation

2x - y = 4

y = 2x -4

comparing the above with

y = mx  + c

m = 2

\(m_{1}\)\(m_{2}\) = -1  ( slope of perpendicular equations)

2\(m_{2}\) = -1

\(m_{2}\)  = -1/2

our slope m = -1/2

We can now go ahead and form our equation

\(x_{1}\) =8   \(y_{1}\) =6

y-\(y_{1}\) = m (x-\(x_{1}\))

y-6 = -\(\frac{1}{2}\)(x-8)

y-6 =  -\(\frac{1}{2}\)x + 4

y=  -\(\frac{1}{2}\)x+4+6

y =  -\(\frac{1}{2}\)x + 10

D

Step-by-step explanation:

Answer: A 1/5

Step-by-step explanation:

Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.

What is probability ?

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

Number of blue marbles = 5,

Number of red marbles = 8,

Number of white marbles = 4,

And number of purple marbles = 3.

Total number of marbles = 5 + 8 + 4 + 3 = 20

Probability of getting blue marble = number of blue marbles/total number of marbles

=5/20=1/4

Apply same formula,

Probability of getting red marble= 8/20 = 2/5

Probability of getting white marble = 4/20 = 1/5

Probability of getting purple marble = 3/20

Answer:

A 1/5

Answer:

$3.10

Step-by-step explanation:

Since there are three necklaces we multiply $3.80 x 3= $11.40

$20.70 - $11.40= 9.30

9.30/3= 3.10

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer: y = 15

Answer:

1/2 half of them are blondies

Step-by-step explanation:

Answer:

Step-by-step explanation:

the answer is 1/2 half of them are blondies

Answer:

a) Missing y-values
x = - 2    ==>   y = 5

x = - 1     ==>   y = 2

x =   1    ==>    y = 2

x =   3   ==>    y  = 10

b) Values of x for y = 4:
x = 1.7 and x = -1.7

Step-by-step explanation:

Given the quadratic function,
y = x² + 1

part a)

to find the y-value for a specific x, just plug in that value of x into the right side and simplify

There are four missing values for

The x values and the corresponding y values are
x = - 2    ==>   y =  (-2)² + 1   =  4 + 1 = 5

x = - 1     ==>   y  =  (-1)²  + 1  =  1 + 1 = 2

x =   1    ==>    y  =   (1)²  + 1  = 1 + 1  = 2

x =   3   ==>    y   =  (3)²  + 1  = 9 + 1 = 10

part b)

The graph has each unit on the grid for the x-axis = 0.5
and
each unit on the grid for the  y-axis  = 2

I got this by seeing that between x = 0 and x = 1 there are two units

the value of y at x = -1 or x = 1 is only one vertical unit on the grid and since y = 2 for these values of x, each vertical unit must be 2

Therefore look at the value of y = 4 (which should be two vertical units) on the graph. You can also draw a horizontal line parallel to the x axis at 2 units from the x-axis

It appears that on the positive x-axis for y = 4, x is about halfway between 1.5 and 2 so I would estimate it at 1.75

On the negative x-axis, at y = 4, x is about halfway between -1.5 and -2 so it would be -1.75

One thing to note about quadratic functions is that you get the same value of y for x and -x

So at y = 4, the two possible values of x are
x = 1.75 and x = -1.75

which when using one decimal place will round to 1.7 and 1;75

I am rounding down rather than rounding up since the x value appears be less than 1.75

Mathematically we can solve for x at y = 4 by plugging in values
y = 4 = x² + 1

x² + 1 = 4

x² = 4 - 1 = 3

x =±√3 = ±1.732

which when rounded to 1 decimal place becomes
x = 1.7 and x = -1.7

Answer:

Step-by-step explanation:

a) y = (-2)² + 1 = 5

y = (-1)² + 1 = 2

y = (1)² + 1 = 2

y = (3)² + 1 = 10

b)  4 = x² + 1

x² = 4 - 1 = 3

x = ±√3 = ±1.7
