Answer: 4/6 or 2/3

Step-by-step explanation:

Step-by-step explanation:

Total sample space , n(s) = 6

Favourable cases of rolling even number,

n(e) = 3

Favourable cases of rolling 5 , n(f) = 1

Probability of rolling an even number or a 5 is

= p(e) + p(f)

= n(e) / n(s) + n(f) / n(s)

= 3 / 6 + 1 / 6

= 4 / 6

= 2/3

Answer:

4.1n

Step-by-step explanation:

Given the equation n – 4.6n – 3.3n + 2.8n , to get its equivalent expression, the following steps must be followed;

Step 1:

Factor out the common variable n

n(1 – 4.6 – 3.3 + 2.8)

Step 2:

Carry out the operation in parentheses;

= n(1+2.8-4.6-3.3)

= n(3.8-4.6-3.3)

= n(3.8-3.3-4.6)

= n(0.5-4.6)

= n(-4.1)

= -4.1n

The equivalent expression is -4.1n

We want to write the equation in the form

y = mx + b.

We need to solve for y.

4x + 2y = -6

Subtract 4x from both sides.

4x - 4x + 2y = -4x - 6

2y = -4x - 6

Divide both sides by 2.

2y/2 = (-4x - 6)/2

y = (-4x - 6)/2

y = -2x - 3

Done.

Answer:

Part 1 : y = 0.75x

Part 2 : $750

Step-by-step explanation:

Part 1

Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.

Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have

sales price = regular price - discount

y = x - 0.25x

y = 0.75x

Part 2:  If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item

Since the sales price, y = 0.75x,and x = regular price = $1000,

substituting x into y, we have

y = 0.75x

y = 0.75($1000)

y = $750

the  area of the lawn in square meters is  60 meters^2

Step-by-step explanation:

The computation of the area of the lawn in square meters is shown below

= 12 meters × 5 meters

= 60 meters ^2

Here we multiply the two sides so that the area of the lawn could be come

Hence, the  area of the lawn in square meters is  60 meters^2

Answer:

14.45

Step-by-step explanation:

Since the solution in this case is C=π(d)/Circumference=pie * diameter you insert 3.14 for pie and 4.6 for the diameter than multiply them together to get 14.444 and it said to round to the nearest hundredth if necessary so now its 14.45.  Hope this helps!

Step-by-step explanation:

because of how its measured

Answer:

Abackyard = (3w + 5)2

Apool = w(w + 10)

Asurround = (3w + 5)2 - w(w + 10)

A=8w2+20w+25

The expression for the area surrounding the pool after the pool is

installed is  (3w + 5)² - w(w + 10).

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

We have,

The pool needs to have a length of 10 feet more than the width.

Then, the area of pool is

= w(w + 10)

and, The backyard have sides measuring 5 feet more than 3 times the width of the pool.

Then, area of backyard

= (3w + 5)²

Now, the area surrounding the pool after the pool is

=  (3w + 5)² - w(w + 10)

Answer:

n=5

Step-by-step explanation:

1/4(2n +6) = 4

Multiply each side by 4

4*1/4(2n +6) = 4*4

(2n +6) = 16

Subtract 6 from each side

2n+6-6 = 16-6

2n = 10

Divide each side by 2

2n/2 = 10/2

n =5

Answer:

n= 5

Step-by-step explanation:

Hello! So to find the value of n, we just multiply 1/4 by the numbers inside the parentheses and then solve for n by dividing. Let's do it!

1/4 (2n + 6) = 4

0.5n + 1.5 = 4

0.5n = 4 - 1.5

0.5n = 2.5

n = 2.5 / 0.5

n = 5

Answer:

25728

Step-by-step explanation:

Amount i would have in 3 months = simple interest + amount deposited

Simple interest = principal x time x interest rate

Principal = 25600

Interest rate = 2%

Time = 3/ 12 = 0.25

25,600 x 0.02 x 0.25 = 128

Total amount = 25,600 + 128 = 25728

Answer:

1.25 m

Step-by-step explanation:

Given that :

Initial height of drop = 20 meters

Rebound after each drop = 1/2 of height

Height after 4th rebound = 5th term of a geometric series

An = a1 * r^(n-1)

a1 = first term = initial drop height

r = common ratio = ratio of rebound per drop = 1/2 = 0.5

A5 = 20 * 0.5^(5 - 1)

A5 = 20 * 0.5^4

A5 = 20 * 0.0625

A5 = 1.25 m

Hence height after 4 reboubd = 1.25 m

Using another method :

1st bounce height = 20 * 0.5 = 10

2nd bounce height = 10 * 0.5 = 5

3rd bounce height = 5 * 0.5 = 2.5

4th bounce height = 2.5 * 0.5 = 1.25

The mean value of Keisha’s data is 1.333333.

The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),

We have the data,

0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.

So, the mean value of data is

= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12

= 16/12

= 4/3

Answer:

1974.6 feets

Step-by-step explanation:

The plane's altitude is : h + 100 feets

To obtain h, according to the attached picture ;

We can use trigonometry :

Tan θ = opposite / Adjacent

Opposite = h ; adjacent = 3000 feets

Tan 32° = h / 3000

h = 3000 * 0.6248693

h = 1874.6080

Plane's altitude :

h + 100 feets

(1874.6080 + 100) feets

= 1974.6 feets
