A number cube is rolled twice. What is the P (2 and then odd number)?

Answers

Answer:

P (2 and then odd number) = [tex]\frac{1}{12}[/tex]

Step-by-step explanation:

Probability refers to chances of occurrence of any event.

A number cube is rolled twice.

Possible outcomes are as follows:

[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]

[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]

[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]

[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]

[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]

[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]

Total number of outcomes = 36

Favorable outcomes include outcomes with 2 and then odd number.

So,

Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]

Number of favorable outcomes = 3

Probability is equal to number of favorable outcomes divided by total number of outcomes.

Therefore,

P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes

[tex]=\frac{3}{36}[/tex]

[tex]=\frac{1}{12}[/tex]

[tex]\frac{8}{52}[/tex] = 0.15384615384 = 15.38%

Step-by-step explanation:

There are 4 7 cards and 4 queen cards so,

[tex]\frac{4}{52}[/tex] + [tex]\frac{4}{52}[/tex] = [tex]\frac{8}{52}[/tex]

23% more than the number last week. This week, there were 7134 new cases. How many new cases were there last week?

Answers

Answer:

Number of cases sold last week= 31,017 cases

Step-by-step explanation:

Giving the following information:

Increase in sales= 23%

This week, there were 7,134 new cases.

If 7,134 cases represent the 23%, then we need to use the rule of three:

Number of cases sold last week= (7,134*100)/23

Number of cases sold last week= 31,017 cases

Indicate the equation of the given line in standard form.

The line that contains the point Q( 1, -2) and is parallel to the line whose equation is

y - 4 = 2/3 (x - 3)

Answers

Answer:

The equation of the line is;

3y = 2x-8

Step-by-step explanation:

Firstly, we need the to get the slope of the given line

To do this, we will write the equation of the line in the standard form

the standard form

is;

y = mx + b

where m is the slope and b is the y-intercept

y -4 = 2/3(x-3)

y -4 = 2x/3 - 2

y = 2x/3 -2 + 4

y = 2x/3 + 2

with respect to the given equation, the slope of the line is 2/3

Mathematically, when two lines are parallel, the slopes of the line are equal

So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)

so;

y = 2x/3 + b

So substitute the values of (1,-2)

1 for x and -2 for y

-2 = 2/3(1) + b

-2 = 2/3 + b

b = -2 - 2/3

b = (-6-2)/3 = -8/3

So the equation of that line is;

y = 2/3x - 8/3

(the numbers with the / is a fraction btw)

Answer:

$50

Step-by-step explanation:

Given data

Let the total purchase be x

Hence 30% of x is $15

Let us find the value of x

30/100*x= 15

0.3*x=15

0.3x=15

x= 15/0.3

x= $50

Hence the purchase is $50

Answer:

$50 is the total

Step-by-step explanation:

30% over 100% = 15 over x

then you cross multiply and get:

30x = 1500

you then divide both sides by 30

30 and 30 cross out

1500 ÷ 30 = $50

put them from least to greatest

Answers

Answer: -7/10, -0.35, 1/5, 0.95

Step-by-step explanation:

-7/10 = -.7

1/5 = 0.2

Answer:

From least to greatest, the correct order is [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

Step-by-step explanation:

Since all negative numbers are smaller than positive, you immediately know that [tex]-\frac{7}{10}[/tex] and -0.35 are smaller than [tex]\frac{1}{5}[/tex] and 0.95. The greater the absolute value of a negative number is, the smaller that number is. Because [tex]-\frac{7}{10}[/tex] is -0.7, which has a greater absolute value than -0.35, this means [tex]-\frac{7}{10}[/tex] is the smallest number, and -0.35 is the second smallest number. Since [tex]\frac{1}{5}[/tex] is 0.2 which is smaller than 0.95, the correct order from least to greatest would be [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

68 - 56 = 12

Hope this helps

Answer:

The answer is 25.125

Step-by-step explanation:

The answer would be 25.125 cubic inches because if you take the volume of a cube that has one side of 3.5 just multiply 3.5x3.5x3.5. This would give you 42.875. Then you have the area of a base which is already squared and you would multiply that with 4.25 to get 68 in cubed. You then know that 42.875 is the volume of the speaker and you are putting it in the box that has a volume of 68. To find what volume is left, you would subtract 42.875 from 68 to get 25.125 in cubed.
