Answer:

Option A , C, D are true.

Step-by-step explanation:

Given : In a carnival game, there is a 45% probability of winning a prize.

To find : Which of the following is true.

Solution : Probability of winning a prize is 45%

or \frac{45}{100}=\frac{9}{20}=0.45

Total probability of an event is 1

Probability of winning is 0.45

Then probability of loosing is 1-0.45=0.55

or 0.55=\frac{55}{100}=\frac{11}{20}

From the results we can say that,

A) The probability that you won't win is 11/20   is true

B) The probability that you will win is 4.5  is false

C) The probability that you won't win is 0.55  is true

D) The probability that you will win is 9/20 is true

Therefore, Option A , C, D are true and B is false.

Ok, here is what I got:
<span>9/20 is .45 so D is right for sure. C is also correct since the remaining % is 55 ( meaning the percent you won't win) this is also the same as A which is 11/20 or .55. again meaning that .55 is the probability that you won't win. I hope this helps!</span>

Solve the following proportion.<br> х<br> 42<br> 35<br> 10
anzhelika [568]

Answer:

12

Step-by-step explanation:

The proportion is equal to \frac{x}{10}=\frac{42}{35}

We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

60=5x

Dividing both sides by 5, we have the answer as

x=12

The graph of a line has a slope of -7 and a y intercept of (0,0). Rewrite the equation in standard form (Ax+By=C) with a positiv
Anna11 [10]

Answer:

the equation of the line is 7x + y = 0 .

Step-by-step explanation:

in the standard form of the line that is Ax +By = C we can write it in the form of

By = C - Ax

y = \frac{-A}{B}x +\frac{C}{B}

which is in the form of y = mx +c

where m is the slope of the line and c is y intercept made by the line.

comparing  y = \frac{-A}{B}x +\frac{C}{B} and  y = mx +c

we get that \frac{-A}{B} =m and \frac{-C}{B} = c

since it is given that slope of the line is -7 therefore m = -7 and c = 0

therefore  \frac{-A}{B} =-7 and \frac{-C}{B} = 0

therefore C = 0 , A = 7 and B = 1

therefore the equation becomes 7x + y = 0

8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49
-7x=-49-16
-7x=-65 divides each side by -7
-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.

Hope this helps!
