Next week, Wendy is going on a 4-day ski trip to Mount Flurry. She wants to ski on fresh powder, so she checks the weather forecast. Each day has a 60% chance of snow. How likely is it to snow on all 4 days?
Wendy simulates the situation by creating a deck of 20 cards, each labeled with a different number from 1 to 20. She picks a card, then returns it to the deck, 4 times. Each time a number greater than 8 appears, it represents a snowy day.
This table shows the results of 100 trials:
Please help.
Answer:
1 60% 2 8.3
Step-by-step explanation:
probability that the snow will fall on 60%.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.

All of the following are equivalent to 2(2a + b) + 8, except _____.
A. 4 a + 2 b + 8
B. 4( a + b + 2)
C. 4 a + 2( b + 4)
Answer:
B. 4( a + b + 2)
Step-by-step explanation:
Task: Simplify 2(2a + b) + 8
1. Distribute the 2
4a + 2b + 8
---------------------
Evidently, that is the same as A, so A is correct.
Now if we try C, 4a + 2(b+4), we see we need to simplify to check.
So let us distibute the 2.
4a + 2b + 8. Also correct.
This probably means that B is incorrect.
4(a + b + 2)
Let's distribute the 4.
4a + 4b + 8
This is incorrect because only have two "b".

Using the triangle below, set up and solve an equation in order to find the value of x.
Answer:
x = 180 - 118 - 34.6 = 27.4
Step-by-step explanation:
The sum of the internal angles of each type of (2D) polygon will only have 1 specific value for each polygon. In the case of a triangle, the interior angles add up to 180 degrees.
Using a statement-reason approach, we start by saying:
Q^ + R^ + S^ = 180 degrees (*) Interior angles of a triangle = 180
(*Please use proper notation if you were already taught it - these computer keyboards can only do so much you know...)
Then you just solve normally for x:
34.6 + 118 + x = 180
x = 180 - 118 - 34.6
x = 27.4 degrees

Here it is: 20% of a number is x. What is 100% of the number? Assume x > 0.
Answer:
5x is 100% of the number.
Step-by-step explanation:
100/20=5%
5*x=5x percent.
x is 20% of Number
x = (0.2) x (number) .
Divide each side by 0.2 : Number = x / 0.2
Number = 5x .
'x' can be anything, even zero. This equation works for x=any number.

Step-by-step explanation:
10 = 0.5n + 1.5
0.5n + 1.5 = 10
0.5n x 10 + 1.5 x 10 = 10 x 10
5n + 15 = 100
5n + 15 - 15 = 100 - 15

→ 48 text messages
Step-by-step explanation:
Were being asked how many text messages are to Bianca. Today, were using 3 ways on how to solve this problem. 2 are incorrect and 1 is correct.
First, let's use addition.
[tex]120+\frac{4}{5} +\frac{1}{2} =121.3[/tex]
Were not looking for 121.3, it's too high. Therefore, using addition is incorrect.
Second, let's use subtraction..
[tex]120-\frac{4}{5} -\frac{1}{2} =118.7[/tex]
Were not looking for 118.7 either. Therefore, using subtraction is incorrect as well.
Third, let's use multiplication...
[tex]120 * \frac{4}{5} * \frac{1}{2} = 48[/tex]
As a result we got 48. Which is the answer your looking for.
Hope this helped! :^)

Please help me! thanks
Answer:
1) 16
2) 20
3) -12
4) 16
Step-by-step explanation:
1) Substitute the r for 4 like it tells you in the question so 12 + 4 = 16.
2) Substitute d with -3 so 5(-3+7) = 5 x (4) = 20
3) Substitute m for 4 so -48 / 4 = -12
4) Angle of triangle is half base times height or 1/2 x b x h
And since the base is 4 and the height is 8:
1/2 x 4 x 8 = 1/2 x 32 = 16
Or in other words:
1/2 x 32 = 32 / 2 = 16
