How to solve rolled dice problems?

From the given ,question Abbie, Chloe, and Xander are playing a dice game.

They are playing with two dices.

The game rules are;

Same number on both dice = +3

Different numbers, with an even sum = +1

An odd sum = -2

After five rounds, score of Chloe = +1

1 = 3 + 1 + (-2) + (-2) + 1

⇒ Same number on both dice ( in first throw) + Different numbers ,with an even sum (in second throw) + An odd sum(third throw) + An odd sum(fourth throw) + Different numbers ,with an even sum (in fifth throw)

If we alter the arrangements, In each case you will get sum as (+1), as integers satisfy both Commutativity and Associativity with respect to addition.

rotate the triangle through 180 degrees about the origin?

Answers

Answer:

Step-by-step explanation:

(1,1) ==> (-1,-1)

(4,2)==>(-4,-2)

(4,4)==> (-4,-4)

The triangle is shown below, after rotting 180 degrees about the origin.

What is a triangle?

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

Given that,

The coordinates of the vertices of triangle = (1, 2), (4, 2) and (4,4).

When the triangle is rotated through 180 degrees about the origin,

The sing of the vertices changes.

The sign will be changed as.

(1, 2) = (-1, -2)

(4, 2) = (-4, -2)

(4, 4) = (-4, -4)

Which statements are true and supported by the data in the table? Check all that apply.
The data for store 1 shows greater variability.
The median number of hours worked for the two stores is the same.
The mean of the data for store 1 is greater than the mean of the data for store 2.
The interquartile range of both data sets is the same.
The range of the data for store 1 is less than the range of the data for store 2.

Answers

Answer:

The correct options are;

1) The data for store 1 show greater variability

2) The mean of the data for store 1 is greater than the mean of the data for store 2

Step-by-step explanation:

The given information are;

Hours worked in a week

Store 1

16, 28, 36, 40, 78

Store 2

22, 27, 33, 36, 40

Using an online application, we have;

For store 1

The range is 78 - 16 = 62

Mean  = 39.6

Standard deviation ≈ 20.88 (Higher variability)

Median = 36

Lower quartile = 22

Upper quartile = 59

Interquartile range = 59 - 22 = 37

For store 2

The range is 40 - 22 = 18

Mean  = 31.6

Standard deviation ≈ 6.41  (Lower variability)

Median = 33

Lower quartile = 24.5

Upper quartile = 38

Interquartile range = 38 - 24.5 = 13.5

Answer:

The correct answers are:

1) The data for store 1 shows greater variability.

3) The mean of the data for store 1 is greater than the mean of the data for store 2.

ZA and ZB are complementary angles. If mZA = (7x + 23)° and
mZB = (5x + 19)°, then find the measure of ZB.

Answers

Answer:

ZB= 39°

Step-by-step explanation:

complementary angles are angles that add up to equal 90

equation:  7x + 23 + 5x + 19 = 90

add like terms: 12x + 42 = 90

subtract 42 from both sides: 12x = 48

divide both sides by 12: x = 4

plug in the value of x to the equation for ZB: 5(4) + 19

simplify: ZB= 39°

The cost of using a telephone in a hotel meeting
room is $0.20 per minute. Which of the following
equations represents the total cost in dollars, for
h hours of phone use?

Answers

so its 12 dollars an hour

x means the cost

12(h)= x

Answer:

c = 0.20 (60h)

Step-by-step explanation:

The hotel charges $0.20 per minute to use the meeting‑room phone.  This per‑minute rate can be converted to the hourly rate using the conversion 1 hour =60 minutes, as shown in the following equation.

​[tex]\frac{0.20}{minute}[/tex]  × [tex]\frac{60 minutes}{1 hour}[/tex] =[tex]\frac{0.20 * 60}{hour}[/tex]

Thus, the hotel charges 0.20×60 per hour to use the meeting‑room phone.

Therefore, the cost c, in dollars, for h hours of use is c=(0.20×60)h which is equivalent to c=0.20(60h).

It costs $2.37 to paint one square foot of wall. You need to paint a wall that measures 864.5 square feet. It will cost to paint that wall. (Round your answer to the nearest hundredth)
a $204.88
b $2,048.87
c $2,048.86
d. $2,848.87 ​

Answers

Answer:

B- hope this helps:)

Step-by-step explanation:

The total cost to paint 864.5 square feet of wall is $2,048.87.

It is given that the cost to paint one square foot of wall is $2.37.

We are asked to find the total cost to paint 864.5 square feet of wall.

What are the different place values in a given number with a decimal point?

If we have a number that has a decimal point then we have two parts.

The whole number part and the fractional part.

After the decimal point, we will count the place value as tenths, hundredths, thousandths, and so on.

You can also see the given figure below.

We know that,

One square foot = $2.37.

Remember that Feet is the plural form of the foot.

We can write,

864.5 square feet = 864.5 x  one square foot

Because in 864.5 square feet we have 864.5 one square foot.

And since one square foot cost $2.37.

864.5 square feet will cost 864.5 x 2.37 dollars.

Now,

864.5 x 2.37 = $2048.865.

Rounding to the nearest hundredth.

6 is in the hundredth place so we will round 86 to 87 since the number in the thousandth place is greater than 4.

Thus the total cost to paint a wall of 864.5 square feet is $2,048.87.

From attacking villagers and stealing livestock, these lizards are mean and aggressive creatures.
