Answer:
x = 1.23529
Step-by-step explanation:
Step 1: Write equation
3/17 = x/7
Step 2: Solve for <em>x</em>
- Cross multiply: 21 = 17x
- Divide both sides by 17: 21/17 = x
- Rewrite: x = 21/17
- Convert to decimal: x = 1.23529
0.13...The 3 repeats forever
Answer:
You have to compare if true some of the statements.
Most of these type questions would be compare the first three data
1. Prices of red to yellow mean we need to add them all up to begin with. 10 x £29.95 + 5 x 35.99 etc. = 15 items or add one zero (x10) to 29.95 and for 35.99 we add zero (x10) then divide by 2 ie) 359.9/2 = 360/2-0.2 = 180 - 0.2 = $179.98
2. Higher and lower comparisments we just take away from total.
3. The difference or how much more something is we subtract from the full total.
This would be a 4 way thought process below;
1. Prices in $ could mean groups, mean high or low we need to count how many items and add up all the prices to find the mean by adding them together.
2. Colour's could mean more red than yellow over a certain price or under a certain price.
3. Colour could also mean how many as a combined data were higher or lower than a certain price. ie) Higher than $29.99 would mean all the data set at $30.00 more. LEss would mean lower than $29.98
4. Mean and fx would be all the prices added together + all the items togather for the fx we multiply the individual groups and create a new box. We then multiple it to the other totals. This can also help establish or be compared to the percentage for advanced data tables.
Step-by-step explanation:
Probability = (number of ways to succeed) / (total possible outcomes) .
The total possible results of rolling two dice is
(6 on the first cube) x (6 on the second one) = 36 possibilities.
How many are successful ? I need you to clarify something first.
You said that the 'second die' shows an odd number. When a pair
of dice is rolled, the problem usually doesn't distinguish between them.
And in fact, you said that they're "tossed together" (like a spinach and
arugula salad ?) so I would understand that they would lose their identity
unless they were, say, painted different colors, and we wouldn't know
which one is the second one.
Oh well, I'll just work it both ways:
First way:
Two identical dice are tossed.
The total is 5 and ONE cube shows an odd number.
How can that happen ?
1 ... 4
4 ... 1
3 ... 2
2 ... 3
Four possibilities. Probability = 4/36 = 1/9 = 11.1% .
=======================================
Second way:
A black and a white cube are tossed together.
The total is 5 and the white cube shows an odd number.
How can that happen:
B ... W
4 .... 1
2 .... 3
Only two possibilities. Probability = 2/36 = 1/18 = 5.6% .
