The frequency for rolling a 3 would be 5 out of 100
Answer:
It isn't a proportional relationship
Step-by-step explanation:
It's not a proportional relationship because you would have to divide both numbers on the chart by a number they both have in common and when you divide them and it doesn't equal 0 then it is not a proportional relationship.
250×.40 = 100.00
250.00+100.00 =350.00
your answer is $350.00
Answer:
Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:
2, 2, 3, 4, 6, 6, 9.
7 numbers total.
2 + 2 + 3 + 4 + 6 + 6 + 9 = 32
32 ÷ 7 = 4.57
The mean would be 4.57.
Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:
2, 2, 3, 4, 6, 6, 9
2, 3, 4, 6, 6
3, 4, 6
4
4 would be the median.
Mode- the largest number on the data.
Range- subtract the mode (largest number) from the smallest number to get range. For example:
2, 2, 3, 4, 6, 6, 9
9 - 2 = 7
7 would be the range.
Step-by-step explanation:
Answer:
X = 14 kg
Y= 7 kg
Step-by-step explanation:
LET X and Y equal the amounts of brand X and Y
X = kg of brand X
Y = kg of brand Y
we know:
1) X + Y = 21 (kg)
2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)
Coefficients 1,4,2 are the cost/kg)
substitute eq. 1 (X+Y), = 21 into right side of equation 2
1X + 4Y = (21)*2
use elimination to solve 2 equations
X + Y = 21
X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)
------------------
0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg
