Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in one variable will cause a corresponding increase in the other variable.
If two variables are inversely proportional, it means that an increase in one variable will cause a corresponding decrease in the other variable.
The variable z is directly proportional to x, and inversely proportional to y. If we introduce a constant k, the equation would be
z = kx/y
When x is 14 and y is 10, z has the value 26.6. It means that
26.6 = 14k/10
Cross multiplying, it becomes
26.6 × 10 = 14k
266 = 14k
k = 266/14
k = 19
The equation becomes
z = 19x/y
When x = 24, and y = 15, the value of z would be
z = 19 × 24/15
z = 30.4
Answer:
2190 r. 4
Step-by-step explanation:
4 REMAINING
Answer:
22 degrees
Step-by-step explanation:
AT y=0 t = -7
at y = 38000 t= -29
What is the difference in temperature
t(0) - t(3800) = -7 - (-29) = -7+29 = 22
The difference is 22 degrees
The probability is (0.10 * 0.50 + 0.01 * 0.20 + 0.89 * 0.01) * 100% = 6.09%.
Answer:
a≥0
Step-by-step explanation:
The equation on the left is absolute value so all values plugged in will be positive but on the other side if a negative was plugged in it would still be negative and thus result in a lower sum than the other side. For example:
|-2+5|=-2+5
7=3
this is untrue.
the equation would only be true if the a values were positive.
