Using it's concept, it is found that there is a 0.0278 = 2.78% probability that Julia spins a “6” followed by a “2”.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

The probability of both events is given by:

[tex]p = P(A)P(B) = \frac{1}{6} \times \frac{1}{6} = \frac{1}{36} = 0.0278[/tex]

0.0278 = 2.78% probability that Julia spins a “6” followed by a “2”.

Answer: 215π

Step-by-step explanation:

If you think of the entire thing as two circles, it makes the problem a lot easier. If we were to find the area of the white "circle" and subtract it from the blue "circle", we would get the area of the ring. First, use the outer radius to find the area of this circle:

[tex]Area=\pi r^2[/tex]

[tex]Area=\pi (24)^2=576\pi[/tex]

Now find the area of the inner circle:

[tex]Area=\pi r^2[/tex]

[tex]Area=\pi (19)^2=361\pi[/tex]

Subtract the area of the inner circle from the area of the outer circle:

[tex]576\pi -361\pi =215\pi[/tex]

The sum of the considered expression is evaluated to be [tex]\dfrac{x+6}{x+3}[/tex]

Finding the least common multiples of the denominator expressions can help. Then using the similar method as we use in sum of fractions would give the sum of algebraic fractions.

For example,

[tex]\dfrac{a}b} + \dfrac{c}{d} = \dfrac{a \times d + c \times b}{bd}[/tex]

For the considered case, the sum of the given expression is easy to evaluate as the denominators are all same, so their sum will directly apply to their numerators.

The sum is evaluated as follows:

[tex]\dfrac{x}{x+3} + \dfrac{2}{x+3} + \dfrac{2}{x+3} = \dfrac{x + 2 + 3}{x+3} = \dfrac{x + 6}{x+3}[/tex]

Thus, the sum of the considered expression is evaluated to be [tex]\dfrac{x+6}{x+3}[/tex]

Answer:

x = 15

Step-by-step explanation:

10x - 30 and 3x + 15 are same- side interior angles and sum to 180° , so

10x - 30 + 3x + 15 = 180 , that is

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15

Answer: 50

"deci" means tenth, so "decimeter" means "tenth of a meter"

0.10 meter = 1 decimeter

1 meter = 10 decimeters (multiply both sides by 10)

5 meters = 50 decimeters (multiply both sides by 5)

The radius of the circle is the distance between the center and the y-intercept.

The radius of the circle is 4 units

The given parameters are:

Center = (0,3)

Y-intercept = (0,7)

The radius is calculated as:

[tex]r = \sqrt{(0 - 0)^2 + (3 - 7)^2}[/tex]

Evaluate

[tex]r = \sqrt{16}[/tex]

Solve

[tex]r =4[/tex]

Hence, the radius of the circle is 4 units

Answer:

t = 4

Step-by-step explanation:

given x varies inversely as t , then the equation relating them is

x = [tex]\frac{k}{t}[/tex]  ← k is the constant of variation

To find k use the condition x = 8 when t = 6 , then

8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )

48 = k

x = [tex]\frac{48}{t}[/tex] ← equation of variation

when x = 12 , then

12 = [tex]\frac{48}{t}[/tex] ( multiply both sides by t )

12t = 48 ( divide both sides by 12 )

t = 4

Step-by-step explanation:

[tex] \frac{5gb}{110} = \frac{2.3gb}{x} [/tex]

→ x = 2.3 ×110÷5 = 50.6 $ Aaron pay

→Brian = 1.1 × 110 ÷5=24.2$

Caleb = 110 - ( 24.2 + 50.6 ) = 110 -74.8 = 35.2$

Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.

To split the bill among the three brothers in proportion to the data they used, we need to calculate the fraction of the total data used by each brother and allocate the bill accordingly.

The total data used by the three brothers is 2.3gb + 1.1gb + 1.6gb = 5gb.

Now, let's calculate the fraction of the bill that each brother should pay based on their data usage:

Aaron's fraction = 2.3gb / 5gb = 0.46

Brian's fraction = 1.1gb / 5gb = 0.22

Caleb's fraction = 1.6gb / 5gb = 0.32

The sum of these fractions should equal 1, representing the entire bill.

To allocate the bill, we multiply each brother's fraction by the total bill amount:

Aaron's payment = 0.46 * $110 = $50.60

Brian's payment = 0.22 * $110 = $24.20

Caleb's payment = 0.32 * $110 = $35.20

Therefore, Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.

Answer:

42 square units

Step-by-step explanation:

Think of the polygon as being the rectangle GPST added to the triangle PES.

total area = area of rectangle GPST + area of triangle PSE

= LW + bh/2

= GT × GP + PS × h / 2

= 7(5) + 7(2)/2

= 35 + 7

= 42

Just a note of the height of the triangle. The height of triangle PSE, h, is the segment with endpoints E and point (2, 2), so its length is 2.

Answer:

y = -2x + 8

Step-by-step explanation:

Solve for y

y + 2 = -2(x - 5)

y + 2 = -2x + 10

y = -2x + 8

y = -2x + 8

Slope-int. form is written as y=mx+b

m is your slope and b is you y intercept

You first will evaluate the -2(x-5) to get:

-2x + 10

Then you'll subtract 2 from each side to get the y alone:

y = -2x + 8

Answer:

Order of operations:

a)parenthesis

 b) exponents

 c) multiplication or/and division from left to right

 d) addition and/ or subtraction from left to right

The most inside parenthesis  are (-4) , (-10), (-5) and those are just negative numbers that we need to combine with others:

4x negative 4 = -16;  2 - negative 10 = 2+10 = 12; and 9 +negative 5 = 9-5 = 4

( 4 x (- 4 )) / ( 2- (-10) +9 +(-5)) =

( 4 x -4 ) / ( 2+10 +9 -5) =

Answer:

Your answer would be Slope m = -3

Step-by-step explanation:

Step 1: Graph the points on a coordinate plane( refer to image!)

Whenever your trying to find a slope of 2 order pairs, remember this

m = rise/run. ( Slope = rise over run.) = Δy/Δx

Now we solve:

M = rise/run = Δy/Δx

M = y2 - y1/x2-x1

M = 5 - (-4) / -5-(-2)

So we get  M = 9/-3 and 9 divided by -3 is -3

So, the slope of (-2,-4) and (-5,5) is -3.
