Answer:

0.64m squared

Step-by-step explanation:

Surface area is the area of the sides added together

I am going to assume that the bottom is a square

0.4 multiplied by 0.6 is 0.24

0.24 halved is 0.12

0.12 multiplied by 4 is 0.48

0.4 multiplied by 0.4 is 0.16

0.48 plus 0.16 is 0.64

Total Surface Area : Area (4 triangles) + Area (square)

4 x 1/2 x 0.4 x 0.6 + (0.4)²
2 x 0.24 + 0.16

Vinil7 [7]

Answer:

A total of 53 sales to qualify for bonus

Step-by-step explanation:

In the first week, they required a sale of 20 tickets to recieve a bonus.

In subsequent weeks, they require a sale of (n + 3)

Where n = number of sale the previous week

Week 2, they'll require n + 3 = (20 + 3) sales = 23 sales

Week 3 = 23 + 3 = 26 sales

Week 4 = 26 + 3 = 29 sales

Week 5 = 29 + 3 = 32 sales

Week 6 = 32 + 3 = 35 sales

Week 7 = 35 + 3 = 38 sales

Week 8 = 38 + 3 = 41 sales

Week 9 = 41 + 3 = 44 sales

Week 10 = 44 + 3 = 47 sales

Week 11 = 47 + 3 = 50 sales

Week 12 = 50 + 3 = 53 sales

At the end of week 12, they require a total of 53 sale to qualify for bonus

In the New York State Numbers Lottery, you pay $1 and can bet that the sum of the numbers that come up is 13. The probability of

Harman [31]

Answer:

The expected value of profit is -0.5125. This is expected loss as value is negative.

Step-by-step explanation:

We are given the following in the question:

P(winning) = 0.075

Thus,

P(Loosing) =

$1 - 0.075 = 0.925$

If we win we gain a profit of $5.50 and if we loose the lottery, we loose $1.

Thus, we can form the probability distribution in the following manner:

Event: Winning Loosing

Profit(x): +5.50 -1

P(x): 0.075 0.925

We have to calculate the expected value of the profit.

$E(X) = \displaystyle\sum x_i(P(x_i))\\E(x) = +5.50(0.075) + (-1)(0.925)\\E(x) = -0.5125$

Thus, the expected value of profit is -0.5125. This is expected loss as value is negative.

Describe the given set with a single equation or with a pair of equations. The plane through the point (7 comma 6 comma negative

devlian [24]

Answer:

(a) Along the xy-plane,

7x + 6y = 0

(b) Along the yz-plan,

2y - 3z = 0

7x - 3z = 0

Step-by-step explanation:

To describe the given set.

Given the plane (7, 6, -3),

We have the equation as

7x + 6y - 3z = 0

(a) Along the xy-plane, z = 0, and we have

7x + 6y = 0

(b) Along the yz-plan, x = 0, and we have

6y - 3z = 0

2y - 3z = 0

7x - 3z = 0
