Answer:

[tex]\dfrac{1}{2}[/tex]

Step-by-step explanation:

Given that:

10 number of blocks which have numbers from 1 through 10.

To find:

Probability of randomly choosing a block that has an even number.

Solution:

The given set of numbers is: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

There are a total of 5 Even numbers are {2, 4, 6, 8, 10}.

And There are a total of 5 Odd number are {1, 3, 5, 7, 9}.

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, Event E is randomly choosing an even number.

Number of favorable cases = 5

Total number of cases = 10

Therefore, the required probability is:

[tex]P(E) = \dfrac{5}{10}\\\Rightarrow P(E) = \dfrac{1}{2}[/tex]

Answer & Step-by-step explanation:

First write the line equation.

y=mx+b is the format where m=slope, b= y intercept

y=-2x-3

plug each x in to see if they match the point

y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO

y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches

y= -2(-6) -3 = 12-3 = 0; point matches so YES

y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO

y = -2(3) -3 = -6-3= -9; point matches so YES

y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO

(-1.5, 0) & (-6, 9) & (3, -9)

Answer: 5890 meters

Step-by-step explanation:

Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.

The lowest point in the valley is 57 meters below sea level.

in integers it is represented by -57 meters. [we use negative integer to represents "below"]

Difference between the highest and lowest point = Highest point - lowest point

=  5,833 meters -(-57) meters

= (5833 + 57) meters      [a-(-b)= a+b]

= 5890 meters

Hence, the required difference = 5890 meters

Answer:

$ 10, 925

Step-by-step explanation:

= $ 10,925

Answer:

120 = 3y + t

Step-by-step explanation:

120 = 3y + t because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.

D(t) = 186,000 t

D(30) = 186,000 • 30

D(30) = 5,800,000 miles

Hope this helps!

The light will travel 5,580,000 miles in 30 seconds.

To understand the calculations, check below.

The distance traveled by light is represented by function.

                   [tex]d(t)=186,000t[/tex]

To find the distance traveled by light in 30 seconds.

Substitute t=30 in the given function.

            d(30) = 186,000 × 30

             d(30) = 5,580,000 miles.

Hence, the light will travel 5,580,000 miles in 30 seconds.

Answer:

2x = y

Step-by-step explanation:

As you can see in the table, y = 2x, this is proven by the fact that if you divide any value in the y of the table by 2 you will get its corresponding x value, proving that 2x = y is the function that is used to represent this table's value.

Answer:

2x = y

Step-by-step explanation:

If x = 10

2x = y

2 * 10 = y

20 = y

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

We know that the perimeter of a circular shape is called the 'circumference', with the formula

When the mirror is cut into half, the diameter gets half as well.

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror  = C = 2πr

                                                                           = 2(3.14)6

                                                                            = 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Answer: [tex]y=-5x+21[/tex]

Step-by-step explanation:

In slope intercept form : y=mx+c , m= slope , c= y-intercept.

Let [tex]L_1[/tex] be the line passing through (5, -4) and perpendicular to [tex]L_2: 2x-10y=0[/tex].

Rewrite [tex]L_2[/tex] in slope-intercept form

[tex]10y=2x\Rightarrow\ y=0.2x+0[/tex]

Here, Slope of [tex]L_2[/tex] = m = 0.2  

Let n be slope of [tex]L_1[/tex] .

Then  [tex]m\times n=-1[/tex]   [Product of slopes of perpendicular lines is -1.]

[tex]\Rightarrow\ n=\dfrac{-1}{m}=\dfrac{-1}{0.2}\\\\\Rightarrow\ n=-5[/tex]

Equation of a line that passes through (a,b) and have slope 'm' is given by :-

[tex](y-b)=m(x-a)[/tex]

So, Equation of [tex]L_1[/tex] :

[tex](y-(-4))=-5(x-5)\\\\\Rightarrow\ (y+4)=-5x+25\\\\\Rightarrow\ y=-5x+21[/tex]

Given that, Mary is planning her birthday party. She's inviting 7 friends and wants to buy party favours. The favours she wants to come in packages of 3.

Since, Each package has 3 favours

if she buys 1, she has 3 party favours

If buys 2, has 6

And, if buys 3, has 9

she can't buy 2 packages, then one friend doesn't get a party favour.

Answer:

(7, -3)

Step-by-step explanation:

Solve the system of linear equations

2x − y = 11

x + 3y = −5

by elimination by addition and subtraction.  Multiply the second equation by -2, obtaining

2x - y = 11

-2x - 6y = 10

------------------

     -7y = 21, which yields y = -3

Knowing that y = -3, we can now find the value of x.  Let's use the first equation for this purpose.  Substituting -3 for y, we get:

2x - (-3) = 11, or

2x = 11 + 3, or 2x = 14.  Thus, x = 7.

The solution is (7, -3).

Answer:

  18

Step-by-step explanation:

There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical  music, 13.

  4 + 3x = 13

  3x = 9 . . . . . subtract 4

  x = 3 . . . . . . divide by 3

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.

  like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18
