Answer:
P(A) = 1/2
Step-by-step explanation:
The question seems incomplete, I assume that we want to find the probability of event A.
Here we have a fair six-sided dice, so each one of the six numbers has exactly the same probability of being rolled.
Such that the possible outcomes of rolling the dice is:
{1, 2, 3, 4, 5, 6}
Now we define event A as rolling an even number.
The possible outcomes such that the event A is true are the even numbers:
{2, 4, 6}
So we have 3 outcomes out of 6.
Then the probability of rolling an even numbers, is just the quotient between the number of outcomes of even numbers (3) and the total number of outcomes (6).
Then:
P(A) = 3/6 = 1/2 = 0.5

Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10.
What are Henry's chances of getting a second turn when he rolls the number cubes? (2 points)
Answer:
Step-by-step explanation:
The even numbers less than 10 are
2 which can only be done 1 way: when you roll snake eyes.
4 can be done 3 ways (2,2) (3,1) and (1, 3)
6 can be done 5 ways (2,4) (4,2) (5,1) (1,5) and (3,3)
8 can be done 5 ways (4,4) (2,6)(6,2)(5,3) and (3, 5)
There are 36 ways of throwing the number cubes.
We have a total of 5 + 5 + 3 + 1 = 14 ways

In a straight line, like the one presented before you, there is 180 degrees. So that means 115 degrees + x is gonna equal 180.
So that means, x is gonna be 180 - 115. So x is 65 degrees

The numerator is the number on the top of a fraction
The denominator is the numer on the bottom of the faction.
Answer:
Step-by-step explanation:

(i) (-7)/5 = -7
(ii) 15/(-4) = 15
(iii) (-17)/(-21) = 17/21 = 17
(iv) 8/9 = 8
(v) 5 = 5/1 = 5
2. Denominator
(I) (-4)/5 = 5
(ii) (11)/(-34) = -34
(iii) (-15)/(-82) = (15/82) = 82
(iv) 15 = 15/ 1 = 1

Answer:
-2/5
Step-by-step explanation:
Given the expression
-4/5 ÷ 2
= -4/5 * 1/2
= (-4*1)/(5*2)
= -4/10
= -2/2 * 2/5
-2/5
Hence the required values is -2/5

Answer:
Step-by-step explanation:
5). Triangle DEF is an equilateral triangle.
Therefore, measure of all sides and the angles of the triangle will be equal.
DE = EF = DF = 5.2 ft
3y + 1 = 5.2
3y = 5.2 - 1
3y = 4.2
y = 1.4
Similarly, m∠D = 60° [Measure of all angles of an isosceles triangle = 60°]
(5x)° = 60°
x = [tex]\frac{60}{5}[/tex]
x = 12
6). Property to be used in ΔFGH,
"Two sides of an isosceles triangle are equal in measure and opposite angles of the equal sides of the triangle are equal"
FG = GH
3y = 12.9
y = 4.3
m∠F = m∠H
4x = 44
x = 11

Answer:
x=7
Step-by-step explanation:
Since this is an isosceles triangle the two angles are equal.
3x+6 = 5x-8
Subtract 3x from each side
3x+6-3x = 5x-8-3x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 = 2x/2
7 = x
Answer:
x = 7
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).
3 x + 6 = 5 x - 8
Subtract 3 x from both side
3 x - 3 x + 6 = 5 x - 3 x - 8
6 = 2 x - 8
add 8 to each side
6 + 8 = 2 x - 8 + 8
14 = 2 x
Divide each side by 2
14 / 2 = 2 x / 2
7 = x
Solve the equation below for x.
3.25x = 8.125
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
Divide each side by 3.25
3.25x/3.25 = 8.125/3.25
x =2.5
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
then divide both sides by 3.25 to get x on its own
x = 2.5

The expression -310 + 15m represents a submarine that began at a depth of 310 feet below sea level and ascended at a rate of 15 feet per minute. What was the depth of the submarine after 8 minutes?
Answer:
190 feet below sea level
Step-by-step explanation:
d = -310 + 15m
d = -310 + 15(8)
d = -310 + 120
d = -190
