Answer:

a dice goes from 1-6

6+1=7

6+2=8

6+3=9

6+4=10

6+5=11

6+6=12

Of those possible choices, 5 are greater than or equal to 8. So the answer is 5/6.

Answer with explanation:

⇒Total Possible outcome when a dice is thrown twice =6²=36

={(1,1),(2,2),(3,3),(4,4),(5,5),(6,6),(1,2),(1,3),(1,4),(1,5),(1,6),(2,3),(2,4).......(6,5)}

→Total Favorable Outcome = Sum of the Number on the dice should be greater than or equal to 8 and one of the dice must show 6.

→A =Sum of the two numbers on the dice should be ,8, 9,10,11,12.

={(4,4),(5,3),(3,5),(6,2),(2,6),(6,3),(3,6),(5,4),(4,5),(5,5),(4,6),(6,4),(6,5),(5,6),(6,6)}

=15

→B={(6,2),(2,6),(6,3),(3,6),(4,6),(6,4),(6,5),(5,6),(6,6)}

→A ∩ B=B

Total Favorable Outcome ={(6,2),(2,6),(6,3),(3,6),(4,6),(6,4),(6,5),(5,6),(6,6)}=9

Required Probability

              =\frac{\text{Total Possible Outcome}}{\text{Total Possible Outcome}}\\\\=\frac{9}{36}\\\\=\frac{1}{4}

Select the graph of y=cot x.
Kisachek [45]

Because of the vertical asymptote and the change in concavity, we conclude that the correct option is B.

<h3>Which is the graph of cotangent of x?</h3>

Remember that cot(x) = 1/tan(x).

Then we can rewrite:

cot(x) = cos(x)/sin(x).

We know that for x = 0, we have:

cot(0) = cos(0)/sin(0) = 1/0

Then we have a vertical asymptote that tends to ± infinity.

The only graph that meets this condition is the second and the third one, and by the curvature (we need to have a change of concavity/convexity) in the tangent function.

From that, we conclude that the correct option is B.

The students on the right hand side had better overall results

There were less people on the left hand side of the room this affects the average even with the right hand side having two zeros, another thing which the left hand side didn’t have.

Use the data set shown below to complete the sentence 3,3,4,5,5,9 the mean the median
lorasvet [3.4K]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ Mean = 4.8  Median = 4.5

The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:

3 + 3 + 4 + 5 + 5 + 9 = 29

29 ÷ 6 = 4.8

To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:

4 + 5 = 9

9 ÷ 2 = 4.5

The difference of twice a number and five is three. Find the number.
ss7ja [257]

let x = a number

difference means that its subtraction

twice a number is 2x

so the equation should be

2x-5=3

add 5 to both sides

2x=8

divide both sides by 2

x=4

On a coordinate plane, a curved line with a minimum value of (5.1, negative 7) and a maximum value of (0, 25), crosses the x-axi
liubo4ka [24]

Answer:

<u>The true statement is D</u>

Step-by-step explanation:

The rest of the question is the attached figure and the statement options.

  • A. Over the interval [–4, –2], the local minimum is 0.
  • B. Over the interval [–2, –1], the local minimum is 25.
  • C. Over the interval [–1, 4], the local minimum is 0.
  • D. Over the interval [4, 7], the local minimum is -7.

============================================================

According to the graph, we will check the options:

A. Over the interval [–4, –2], the local minimum is 0.  (<u>Wrong</u>)

Because the minimum is -12

B. Over the interval [–2, –1], the local minimum is 25.   (<u>Wrong</u>)

Because the minimum is 18

C. Over the interval [–1, 4], the local minimum is 0.  (<u>Wrong</u>)

Because the minimum is at x = 4 less than zero

D. Over the interval [4, 7], the local minimum is -7.    (<u>True</u>)
