The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahe

guapka [62]

1. The paired digits 00 to 99 represent 100 shots.

blocked

Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.

Write your answer in the space below.

The answer is 73 to 99

2. Each group represents the 5 shots taken by the other team. To win the game, the Ice blades 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?

Write your answer in the space below.

The answer to the question Is all 5.

3. Group 1 is a success. Explain why.

Write your answer in the space below.

Group 1 is a success because none of the numbers 73 and 99 show up.

4. In this simulation, which groups are successes? How many successes are there in the 10 groups?

Write your answer in the space below.

1,3,10

There are 3.

5. Estimate the probability the Ice blades will win the game. Give your answer as a percent.

A dust particle weighs 7.42 × 10-10 kilograms. What is the weight of 5 × 106 dust particles represented in scientific notation?

OLEGan [10]

<span>A dust particle weighs 7.42 × 10-10 kilograms.

Weight of 5 × 106 dust particles = </span>5 × 10^6 x 7.42 x 10^(-10)

= 5 x 7.42 x 10^(6-10)

= 37.1 x 10^(-4)

= 3.71 x 10^(-3) kilograms

Graph <br> X-intercept of 3<br> Y-intercept of -8

laiz [17]

Answer:

$\displaystyle 2\frac{2}{3}x - 8$

Step-by-step explanation:

Starting from the y-intercept of $\displaystyle [0, -8],$ you do $\displaystyle \frac{rise}{run}$ by either moving eight blocks <em>south</em><em> </em>over three blocks <em>west</em><em> </em>or eight blocks <em>north</em> over three blocks <em>east</em><em> </em>[<em>west</em> and <em>south</em> are negatives].

If a 12 cm altitude to the hypotenuse of a right triangle divides the hypotenuse into segments with ratio 3:2, what is the lengt

tiny-mole [99]

Answer:

The length of hypotenuse is $10\sqrt{6}$ cm

Step-by-step explanation:

Let's length of hypotenuse is x

Since, a 12 cm altitude to the hypotenuse of a right triangle divides the hypotenuse into segments with ratio 3:2

so,

First part of hypotenuse length is

$=\frac{3}{5}x$

Second part of hypotenuse length is

$=\frac{2}{5}x$

now, we can draw triangle

We can see that

triangles ABD and ABC are similar

so, the ratio of their sides must be equal

$\frac{\frac{3x}{5} }{12}=\frac{12}{\frac{2x}{5}}$

now, we can solve for x

$\frac{3x}{5}\times\frac{2x}{5}=144$

$6x^2=3600$

$x=10\sqrt{6}$

So,

The length of hypotenuse is $10\sqrt{6}$ cm
