The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.
1. The paired digits 00 to 99 represent 100 shots.
Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.
Write your answer in the space below.
2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.
For a group to be a success, how many of the 5 shots does the goalie need to save?

Also 50 points answer because I feel like it lol.
Answers
Answer:
solution given:
3(x+2)+35°+52°=180°[sum of interior angle of a traingle is 180°]
3(x+2)=180-87
x+2=93/3
x+2=31
x=31-2=29°
value of x=29°
again
<C=3(29°+2)=93°
the measure of angle C=93°
Answer:
x = 29
angle c = 93
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we create an equation to solve for x
180 = 3(x+2) + 52 + 35
Now we solve for x using basic algebra
step 1 distribute the 3 to ( x and 2 )
3 * x = 3x
3 * 2 = 6
now we have 180 = 3x + 6 + 52 + 35
step 2 combine like terms
6 + 52 + 35 =93
now we have 180 = 93 + 3x
step 3 subtract 93 from each side
93 - 93 cancels out
180 - 93 = 87
now we have 87 = 3x
step 4 divide each side by 3
3x / 3 = x
87 / 3 = 29
we're left with x = 29
Now we want to find the measure of angle C
To do so we plug in 29 for "x" in 3 ( x + 2)
3 ( 29 + 2 )
29 + 2 = 31
3(31) = 93
Hence angle c = 93

There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.
Answer:
A = 18 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases )
Here h= 3, b₁ = 3 and b₂ = 9 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 9)
= 1.5 × 12
= 18 cm²

Step-by-step explanation:

Answer:
D. 41 and 43
Step-by-step explanation:
To find it, 54 times 6 plus the two numbers then divided by 8 has to equal 51. let a and b be the two numbers
[(54*6) + a + b]8 = 51
(324 + a + b)/8 = 51
324/8 + (a + b)/8 = 51
40.5 + (a + b)/8 = 51
(a + b)/8 = 10.5
a + b = 84
The mean if a and b are 42, what two numbers here have a mean of 42? 41 and 43, 41 + 43 = 84, 84/2 = 42
