Answer:

The perimeter is 24x - 2.

Step-by-step explanation:

The perimeter of a rectangle is found using the following formula: 2(l+w). The length and width added together are 10x - 3 + 2x + 2 or 12x - 1, multiply that by 2 and you'll get that the perimeter is equivalent to 24x - 2.

A manufacturer plans on building a better mousetrap. There is a 60% chance the mouse trap will produce a profit of $200,000 for
maksim [4K]
Expected value E(x) = 0.6(200,000) + 0.2(100,000) - 0.2(200,000) = 120,000 + 20,000 - 40,000 = 100,000

Therefore, the expected value is $100,000, so the company should build the mousetrap.

Determine the angle at the centre of a circle with radius 6.0 cm for an arc length of 8.0 cm.
sveta [45]

Answer:

Third option.

Step-by-step explanation:

You need to remember that the formula used to calculate the arc lenght is:

arc\ length=r C

Where "r" is the radius and "C" is the central angle in radians.

You need to solve for "C":

C=\frac{arc\ length}{r}

You know the radius and the arc lenght, therefore, you can substitute values to calculate the central angle in radians. Therefore, this is:

C=\frac{8.0cm}{6.0cm}

C=\frac{4}{3}radians

4 students from a class of 15 are going to be chosen to be on the dance committee. Find the number of different 4-person committ
Andrej [43]
We know that
The formula for combinations is
C=n!/[(n-r)!*r!]
where
n is the total number of objects you choose from
r is the number that you choose to arrange

in this problem
n=15 students
r=4 students
C=15!/[(15-4)!*4!]-----> C=15!/[11!*4!]---> (15*14*13*12*11!)/(11!*4*3*2*1)
C=(15*14*13*12)/(24)----->C=1365

the answer is
1365
