You roll two six-sided number cubes. Let X be the number of odd numbers that show up on the two cubes. What are the
possible values of X?
0.1.2
0,1,2,3,4,5,6
1,3,5
0,1,3,5

Answers

Answer:

The possible values of X are 0,1 or 2.

Step-by-step explanation:

In this question:

Two number cubes are going to be rolled.

X is the number of odd numbers that show up on the two cubes.

For each cube, there is one number, which can be even, or odd.

Thus, there can be no odd numbers, one odd number or two odd numbers, and the possible values of X are 0,1 or 2.

have a good day :)

Step-by-step explanation:

Answer:

7.43

Step-by-step explanation:

So lets go over a few things:

In decimal form, you start of in the tenths.

So in this case that is 4.

After tenths, is hundreths, thousandths, ten thousandths, etc.

Since hundreths comes after the tenths, that will be 2.

Any number 5 or greater will be rounded up, and any number below 5 is rounde down.

Now, to find if we raise or lower the hundreths(which is 2), we must see if the thousandth splace is above or lower than 5.

We can see that our thousandths is 8.

Since 8 is higher than 5, the 2 in our hundreths place will go up to 3.

So we get:

7.43

Hope this helps!

If 8,a,b,27 are in geometric sequence, find the value of a and b.​

Answers

Answer:

a = 12 and b = 18

Step-by-step explanation:

Given that,

8,a,b,27 are in geometric sequence.

For a GP, the nth term is given by :

[tex]a_n=ar^{n-1}[/tex]

Put n = 4

[tex]a_4=ar^{4-1}\\\\a_4=ar^3\\\\27=8\times r^3\\\\r^3=\dfrac{27}{8}\\\\r=\dfrac{3}{2}=1.5[/tex]

Put n = 2,

[tex]a_2=ar^{2-1}\\\\a=ar\\\\a=8\times 1.5\\\\a=12[/tex]

Put n = 3

[tex]a_3=ar^2\\\\=8\times 1.5^2\\\\b =18[/tex]

So, the values of a and b is 12 and 18 respectively.

le A right triangle has a hypotenuse of 10m and a leg of 5m. What is the length of the second leg? Round to the nearest tenth.​

Answers

Answer:

Length of 2nd leg is 8.7m.

Step-by-step explanation:

a^2 + b^2 = c^2

Substitute.

5^2 + b^2 = 10^2

Solve.

25 + b^2 = 100

100 - 25 = 75

sqrt(75) = 8.66

A mechanical system has 3 subsystems in series, each has reliabilities 98%, 96% and 94%, respectively. What is the overall reliability of the system

Answers

Answer:

The overall reliability of the system is 99.9952%

Step-by-step explanation:

Probability of the system not working:

None working, the first with 2% probability of not working(as it has 98% probability of working), the second with 4% and the third with 6%. So

0.02*0.04*0.06 = 0.000048

Probability of the system working:

1 subtracted by the probability of the systme not working.

1 - 0.000048 = 0.999952

0.999952*100% = 99.9952%

The overall reliability of the system is 99.9952%

At the beach, 49% of people have red towels and 11% have blue towels. If the
rest have white, what percentage of the people at the beach have white
towels?

Answers

Answer: 40%

Step-by-step explanation:

Percentage of people that have red towels = 49%

Percentage of people that have blue towels = 11%

Therefore, the percentage of the people at the beach have white

towels will be:

= 100% - (49% + 11%)

= 100% - 60%

= 40%

What are the distance between the pair of points E(-5,4) and F(6, 4)

Answers

Answer:

[tex]\boxed {\boxed {\sf d=11}}[/tex]

Step-by-step explanation:

Since we want to find the distance between a pair of points, we use the following formula:

[tex]d =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where (x₁, y₁) and (x₂, y₂) are the points.

We are given the points E (-5, 4) and F (6,4). If we match the values and corresponding variables, we see that:

x₁= -5 y₁= 4 x₂= 6 y₂= 4

Substitute the values into the formula.

[tex]d= \sqrt{(6--5)^2+ (4-4)^2[/tex]

Solve inside the parentheses.

(6--5)= (6+5)=11 (4-4)= 0

[tex]d= \sqrt{11)^2+(0)^2[/tex]

Solve the exponents.

(11)²= 11*11= 121 (0)²= 0*0= 0

[tex]d= \sqrt{121+0[/tex]

Add.

[tex]d= \sqrt{121}[/tex]

Solve the square root.

[tex]d= 11[/tex]

The distance between the 2 points is 11.

What are the coordinates of the solution of these two linear equations

Answers

Hi there! The solutions of two linear equations can be broken into 3 types:

Infinitely Many SolutionsOne Solution No Solution

This is from the system of equations where you solve for the y-value and x-value by substitution method or elimination method.

From the question above, the question asks you to find the coordinate of the solution of the equations. But how do we know the coordinate point of the solution if we aren't given any equations? They don't give equatione but they give a graph instead.

Now I would like you to take a look at the graph. You notice that both graphs have one intersect point, right? That point is our solution!

Hence, we can say that an intersection point of two graphs is the solution of both equations.

The graphs intersect each others at (2,1). Thus the answer to this question is (2,1)

Questions can be asked through comment.

Furthermore, an intersection point of two graph is the solution to the equation of the graphs.
