Ulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.

Answers

Answer:

7/ 36

Step-by-step explanation:

Roll of 2 fair six sided die :

Sample space = 6² = 36

Sum of 7:

(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6

Probability = required outcome / Total possible outcomes

Required outcome = 7

Total possible outcomes = 36

P(obtaining a sum of 7) = 7 / 36

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no
less than $1 combined. At least 2 of the coins are nickels and at least 9 of the
coins are dimes. Solve this system of inequalities graphically and determine
one possible solution.

Answers

9514 1404 393

Answer:

 2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the unshaded area the solution space. Here, the vertices of the triangular solution space are ...

  (2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:

  (x, y) = (2, 9), (3, 10), (4, 11)

Given:

In a right angle triangle ABC, [tex]\angle B=90^\circ,x=8.7\ m[/tex], and [tex]\theta = 45^\circ[/tex]

To find:

The value of AC.

Solution:

In a right angle triangle,

[tex]\cos \theta =\dfrac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos \theta =\dfrac{BC}{AC}[/tex]

[tex]\cos (45^\circ) =\dfrac{8.7}{AC}[/tex]

[tex]\dfrac{1}{\sqrt{2}}=\dfrac{8.7}{AC}[/tex]

On cross multiplication, we get

[tex]AC=8.7\times \sqrt{2}[/tex]

[tex]AC=12.30365799[/tex]

[tex]AC\approx 12.304[/tex]

Therefore, the measure of AC is 12.304 m.

the answer is option 2

Answer:

Option 2

Step-by-step explanation:

Given function:

x=8 and y=6x=5 and y=20

Option 1: ×

Table one: y=8-6

if y is 6 then 8-6 can’t be 6 it is 2.

Option 2: √

Table one:

y=8-2

y would be 6 then this would be correct..

Table two:

y=4x

if y=20 then x would be 5 and if y is 16 then x=4.

Option 3:×

y=4x

this is wrong since table 2 is y=4x..

Option 4:×

Table one

y=x-4

if y is 6 and x is 8 then this is wrong..

Therefore, option 2 is correct..

Which part of the sentence is a dependent clause? Read the passage below and answer the question.In the 1930s, the Australian archaeologist V. Gordon Childe proposed that this suite of changes be called the Neolithic Revolution. Archaeologists first used the term Neolithic (or New Stone Age) to describe distinctive polished stone tools that appear from about 10,000 years ago. But Childe insisted that the real significance of this period lay in something more revolutionary: the emergence of agriculture. Agriculture laid the foundations for all the most important developments of later human history. Today, many prehistorians resist Childes term because they know that when examined closely, the changes turn out to have been gradual. Contemporaries could hardly have known they were living through a revolution. Nevertheless, Childes notion of a Neolithic or agrarian revolution deserves to survive, for on the scale of human history as a whole, the changes were both rapid and revolutionary. During a mere 7,500 years, between 11,500 and 4,000 years ago, agricultural communities with domesticated plants and animals appeared in at least three quite separate regions of the world, and perhaps as many as seven.Excerpt From: David Christian, Maps of Time: An Introduction to Big History (2011), 489.Which of the following arguments regarding the relationship between polished stone tools and the emergence of agriculture is most defensible?Choose 1 answer:A: The emergence of agriculture caused the emergence of polished stone toolsB: The emergence of polished stone tools caused the emergence of agriculture(Choice C)The emergence of polished stone tools was unrelated to the emergence of agriculture(Choice D)The emergence of polished stone tools and agriculture were probably related, but whether one caused the other is unclearPLZ HELP PLZ HELP Food can occasionally become contaminated from the food handler or from other food during normal storage or preparation of food.
