Answer:

4/6

Step-by-step explanation:

If there's 6 sectors, and each sector is equal, the probability of the spin landing into any sector has to be the same. Therefore, each sector should be equal to 1, or 1/6. If 4/6 are shaded, there's a 4/6 probability of the spin landing in a shaded sector.

Hope this helps.

Answer:

2/3

Step-by-step explanation:

A certain spinner is divided into 6 sectors of equal size, and the spinner is equally likely to land in any sector. Four of the 6 sectors are shaded, and the remaining sectors are not shaded.

Probability is the likelihood that an event will occur. Probability is a selection over the number of observation.

There are 4 shaded portion of the spinner and two unshaded portion.

The probability that when the spinner is spinned the portion will liand on four is simply

4/6, divided to its lowest term.

In a circle with a 8 in radius, how long, in inches, is an arc associated with 2.6 radians.
Bingel [31]
S = r·α is the formula to find the arc length (s), given the radius (r), and angle measure (α) in radians.
If the angle measure is NOT given in radians you must convert to radians.

s = 8 · 2.6
s = 20.8 in

A toll road company has two plans for customers. One plan charges $10 per month for rental of a transponder (a box that identifi
Lunna [17]

Answer:

The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Step-by-step explanation:

For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:

10+0.60m<0.75m, where:

m is the number of miles driven

Now, you can solve for m:

10<0.75m-0.60m

10<0.15m

10/0.15<m

m>66.6

According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Can someone help with this math question
Tcecarenko [31]
Based on corresponding angles, the upper left angle will be the supplement of 130, which is 50 degrees. The upper right angle is perpendicular, so it is 90 degrees. Since the sum of all internal angles of a triangle is 180, the remaining angle (lower angle) is 40 degrees. This is choice G.

A heated piece of metal cools according to the function c(x) = (.5)x − 7, where x is measured in hours. A device is added that a
Mama L [17]

Answer:

Option (b) is correct.

The temperature of the metal after two hours is 28 Celsius

Step-by-step explanation:

  Given : A heated piece of metal cools according to the function  c(x)=(0.5)^{x-7} ,  where x is measured in hours and then a cooling device id added that aids in cooling according to the function h(x)=-x-2

We have to determine the temperature of the metal after two hours.

Let w(x) denotes the temperature of metal .

Thus, w(x) can be given by function c(x) + h (x) = [c + h](x)

Thus, w(x)=[c+h](x)\\\\w(x)=(0.5)^{x-7}+(-x-2)\\\\ , where x is measured in hours.

Thus, after two hours that is when x = 2

the temperature of metal is given by w(2)

w(x)=(0.5)^{x-7}+(-x-2)\\\\ w(2)=(0.5)^{2-7}+(-2-2)

Solving , we get,

w(2)=(0.5)^{2-7}+(-2-2)\\\\ w(2)=(0.5)^{-5}+(-4)\\\\ w(2)=32-4=28

Thus, the temperature of the metal after two hours is 28 Celsius.

Hence, Option (b) is correct.
