Multiply 2*15

Step-by-step explanation:

2 · 15 - 2 ÷ 5

PEMDAS

Parentheses  none

Exponents  - none

Multiply and divide from left to right

2*15 = 30

Then 2÷5 = .4

30 - .4 = 29.6

Answer:

You would multiply first.

Step-by-step explanation:

The order of operations goes Multiplication or Division then Adding or Subtracting. The equation is 2 × 15 - 2 ÷ 5. Since there you have to multiply and divide you go left to right on the equation. This means that you multiply first.

Step-by-step explanation:

From the picture of a cone attached,

Radius of the circular top = r

Height of the cone = h

Slant height of the cone 'l' = 6

Area of the circular top of the cone with radius 'r' = πr²

Amount of space inside the cone = Volume of the cone = [tex]\frac{1}{2}\pi r^{2} h[/tex]

The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)

The vertical height 'h' of the cone when the cone is standing upright = [tex]\sqrt{6^2-r^2}[/tex]

[By Pythagoras theorem, l² = h² + r² ⇒ h = [tex]\sqrt{l^2-r^2}[/tex]]

The interquartile range is 5.

Given,

The data for the number of pounds of trash collected by each teenager is shown below.

26, 26, 21, 22, 20, 25, 35

We need to find the interquartile range

It is given by:

= Q(3) - Q(1)

Q(3) = median of the upper half

Q(1) = median of the lower half.

Arrange in ascending order.

20, 21, 22, 25, 26, 26, 35

We have,

Lower half

Q(1) = 21

Upper half

Q(3) = 26

Interquartile range:

= Q(3) - Q(1)

= 26 - 21

= 5

Thus the interquartile range is 5.

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = 0.0505

Step-by-step explanation:

Explanation:-

Given mean of the Population 'μ' = 374

Variance of the Population σ² = 1090

Standard deviation of the  Population 'σ ' = √1090 = 33.01

Given 'X' be a random variable in normal distribution

[tex]Z = \frac{x -mean}{S.D} = \frac{320-374}{33.01} = -1.636[/tex]

Z = - 1.64

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = P( Z < - 1.64 )

                   = 1- p(Z > 1.64)

                   = 1 - ( 0.5 + A(1.64)

                   = 0.5 - 0.4495

                  = 0.0505

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = 0.0505

Step-by-step explanation:

g(x)=-2x+6

To find the y intercept set x = 0

g(0) = -2(0) +6

g(0) = 6

The y intercept is 6

(0,6)

To find the x intercept set y = 0

0 = -2(x) +6

Subtract 6 from each side

0-6 = -2x+6-6

-6 = -2x

Divide each side by -2

-6/-2 = -2x/-2

3 = x

The x intercept is 3

(3,0)

Answer:

x-int : 3

y-int : 6

Step-by-step explanation:

in order to find x intercept, you set the function equeal to 0

0= -2x + 6

then solve for x

-6 = -2x

3=x

To solve for the y intercept, you plug in 0 for x

y = -2(0) + 6

then solve  for y

y = 6

Answer:

[tex](x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}[/tex]

Step-by-step explanation:

So, we know that the center of the circle is at (-6, -7/6).

To find the equation of our circle that is tangent to the x-axis, we just need to find the vertical distance from our center to the x-axis.

Our center is at (-6, -7/6). The vertical distance from this to the x-axis directly above will be (-6, 0).

So, find our distance by subtracting our x-values:

[tex]d=r=0-(-7/6)[/tex]

Subtract:

[tex]d=r=7/6[/tex]

So, our distance, which is also our radius, will be 7/6.

Now, we can use the standard form for a circle, which is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the center and r is the radius.

Substitute -6 for h, -7/6 for k, and 7/6 for r. This yields:

[tex](x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}[/tex]

We can confirm by graphing (using a calculator):

Answer:

162

Step-by-step explanation:

[tex] { \sqrt{xy} } = 3[/tex]

[tex] = > ( { \sqrt{xy} })^{2} = {3}^{2} [/tex]

[tex] = > xy = 9[/tex]

Also ,

[tex]x - y = 12[/tex]

[tex] = > {(x - y)}^{2} = {12}^{2} [/tex]

[tex] = > {x}^{2} + {y}^{2} - 2xy = 144[/tex]

Putting the value of 'xy' above gives :-

[tex] {x}^{2} + {y}^{2} - 2 \times 9 = 144[/tex]

[tex] = > {x}^{2} + {y}^{2} = 144 + 18 = 162[/tex]

Answer:

y = 8x+8

Step-by-step explanation:

We can solve for the function by finding the slope of the linear function using two points. Let's use (0,8) and (1,16)

Slope formula is: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Plug in the 2 points: [tex]m = \frac{16-8}{1-0}[/tex]

Simplify: m = 8

So now, for the equation y = mx+b, we have m which is y = 8x+b

Now we need to find b by using another point from this linear function.

We can use the point (2,24).

Plug this point into the equation y = 8x+b

We have now found the equation of the linear function: y = 8x+8

5-7 x = 2

Step-by-step explanation:

a number times negative seven added to five equals two

"a number times negative seven added to five equals two" is represented by expression 5-7x=2

An expression is combination of variables, numbers and operators.

The given sentence is "a number times negative seven added to five equals two"

Here let us consider the unknown number to be x.

As in the sentence we have a number times negative seven.

Times in the sentence means product. So the number x is multiplied with -7. i.e is -7x

Now a number times negative seven added to five.

This means 5 is added to -7x

-7x+5

"a number times negative seven added to five equals two" means -7x+5 is equal to two

-7x+5=2

5-7x=2

Hence the "a number times negative seven added to five equals two" is represented by expression 5-7x=2

Answer: 0.0051

Step-by-step explanation:

Given the following :

Average Population weight (m) = 190

Population standard deviation (σ) = 35

Total weight of 25commuters (x) = 5200

Sample mean = 5200 /25 = 108

Sample standard deviation = standard error :

σ / √n = 35/√25 =

35/5 = 7

Zscore = (x - m) / standard error

Zscore = (208 - 190) / 7

Zscore = 18 / 7

= 2.57

P( Z > 2.57) = 1 - p(Z < 2.57)

P(z < 2.57) = 0.9949

1 - p(Z < 2.57) = 1 - 0.9949 = 0.0051

The last graph

Step-by-step explanation:

Graphs 3 and 4 have negative rates of change.

Options C and D are the correct answer.

We have,

The rate of change  for the interval 0 to 2 for each graph can be calculated as:

= (b - a) / (2 - 0)

Where (0, a) and (2, b) are the coordinates on each line.

Now,

Graph 1:

Rate of change.

=  (0 - (-3) / (2 - 0)

= 3/2

Graph 2:

Rate of change.

=  (-2 - (-3) / (2 - 0)

= (-2 + 3) / 2

= 1/2

Graph 3:

Rate of change.

= (-4 - (-3) / (2 - 0)

= (-4 + 3) / 2

= -1/2

Graph 4:

Rate of change.

= (0.5 - 2) / (2 - 0)

= -1.5 / 2

LM+MO=LO

7x-9+14=10x-7

The length of LO is 33 inches.

It is given that LM = 7x - 9.

MO = 14

LO = 10x - 7

Equation is the combination of variables, constant and mathematical symbols.

M is between L and O  

                           LM + MO = LO

                       7x - 9 + 14 = 10x - 7

                      7x - 10x = -7 + 9 - 14

                         - 3x = - 21 + 9

                           - 3x = - 12

                             x = 12/3              

                               x = 4

So , putting the value of x in LO = 10x - 7

                                               LO = 10 (4) -7

                                                LO = 40 -7

                                                  LO = 33 inches

Answer:

what is it then

Step-by-step explanation:

Answer:

a. 75.3% is the expected percentage and this value corresponds to 753 million dollars

b. 34.62% of items corresponds to 75% of this sales volume

Step-by-step explanation:

a. A =x(1-y)/(y-x)

X = 0.15, y = 0.50

A = 0.15(1-0.50)/(0.50-0.15)

= 0.15(0.5)/0.35

A = 0.2143

we have

x = 0.35

y = 0.35(1+0.2143)/(0.2143+0.35)

y = 0.425005/0.5643

y = 0.7531

y = 75.3%

75.3% is the expected percentage and this value corresponds to 753 million dollars

b. y = 0.75

find x

y = x(1+A)/(A+x)

x = yA/(1+A-y)

x = 0.75(0.2143)/1+0.2143-0.75)

x = 0.160725/0.4643

x = 0.3462

34.62% of items corresponds to 75% of this sales volume
