Answer:
8/15
Step-by-step explanation:
To divide by a fraction, change the division to a multiplication, and flip the fraction.
2/5 / 3/4 = 2/5 * 4/3 = 8/15
Step-by-step explanation:
A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable
If two triangles are similar, that means their side lengths are proportional, so we get the equation
Thus x = 13.6.
Hope that helped!
Answer:
x + y=24
x=24-y = 3x+5y=100
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
<span>a. The number of cantaloupes sold at Central varied less than did the number sold at North.
</span>What is the MAD of the data set?
<span>{10, 9, 16, 5, 10}
</span>
mean = (10 + 9 + 16 + 5 + 10)/5 = 10
MAD = ( (10 - 10) + (10 - 9) + (16 - 10) + (10 - 5) + (10 - 10) )/5 = 12/5
The numbers of cubs in each litter were 1, 1, 2, 2, 3, 3, 3, 4, 5, and 6. The mean of these measurements is 3.
What is the mean absolute deviation?
mad = ( (3 - 1) + (3 - 1) + (3 - 2) + (3 - 2) + (4 - 3) + (5 - 3) + (6 - 3) )/10
a. 1.2
Tamar surveyed six friends, asking each how many times he or she had ridden in a helicopter. The numbers of times she recorded were 0, 0, 0, 1, 3, and 8.
What is the mean absolute deviation of the number of times? Round to the nearest tenth, if needed.
mean = (1+3+8)/6 = 2
mad = ( 2 + 2 + 2 + (2 - 1) + (3 - 2) + (8 - 2) )/6 = 14/6
c. 2.3 times
Four friends played cards. Their final scores were –6, –3, 0, and 1.
<span>What is the mean absolute deviation of their scores?
</span>
mean = (-6 - 3 - 1)/4= -10/4 = -2.5
mad = ( (6 - 2.5) + (3 - 2-5) + 2.5 + (2.5 + 1) )/2.5
mad = 4
