Answer: 400

Step-by-step explanation:

From the question, we are informed that the probability of getting a 6 is 4/5 and that the dice is rolled 500 times.

The number of sixes that would be expected to roll will be 4/5 multiplied by the number the dice is rolled

= 4/5 × 500

= 400

There'll be 400 sixes.

27.) Find the sum of the length of line segments EF and CD

Lelechka [254]

Answer:

5√10

Step-by-step explanation:

The distance between two points A( $x_1,y_1$ ) and B( $x_2,y_2$ ) on the coordinate plane is given by:

$|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }$

From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).

Hence the lengths of the line segment EF and CD are:

$|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}$

Which phrase matches the algebraic expression below? 2(x - 7) +10

Ierofanga [76]

Answer:

2 times the difference of x minus 7 plus 10

Step-by-step explanation:

When dealing with equations, you ALWAYS do the parentheses first. The first relationship x and 7 are going to have is being subtracted from eachother. Once you do that, you can do the rest of the equation. Hope this helps!
