175 meters
Step-by-step explanation:
25*5=175 meters
Answer:
1.
2.
Step-by-step explanation:
Given
Variation: inverse Proportion
y = 7, x = 9
Required
- Write an equation connecting y and x
- Find y when x = 21
Given that thee variation is inversely proportional;
This implies that
Convert variation to equation
----------- Equation 1
Where k is the constant of variation
Substitute 7 for y and 9 for x in equation 1
Multiply both sides by 9
Substitute 63 for k in equation 1
Multiply both sides by x
Hence, the equation connecting x and y is
Solving for when x = 21
Substitute 21 for x in the above equation
Divide both sides by 21
f(x) = (3/4)ˣ - 4
As x gets really negative (3/4)ˣ grows positively without bound (because it's (4/3)⁻ˣ and 4/3 > 1).
As x gets really positive (3/4)ˣ tends to zero but never quite gets there.
So (3/4)ˣ > 0 for all x
So f(x) > 0 - 4 for all x
Answer: { y | y > -4 }, first choice
Answer:
Let the total numbers of cars be ten then the total cars produced in one week would be 50
Probability of deficient cars on Monday = 4/10
Probability of deficient cars on Tuesday =1/10
Probability of deficient cars on Wednesday = 1/10
Probability of deficient cars on Thursday = 1/10
Probability of deficient cars on Friday = 3/10
Probability ( deficient car)= 10/50 or 1/5
Probability that it produced on Monday 4/10*1/5= 4/50= 2/25= 8/100= 0.08 or 8%
Probability of deficient cars on Monday = 4/10* 12/100= 48/1000= 0.048or 4.8%
Probability of deficient cars on Tuesday =1/10 *22/100= 22/1000= 0.022 or 2.2%
Probability of deficient cars on Wednesday = 1/10*22/100=22/1000= 0.022 or 2.2%
Probability of deficient cars on Thursday = 1/10*22/100=22/1000= 0.022 or 2.2%
Probability of deficient cars on Friday = 3/10*22/100= 66/1000= 0.066 or 6.6%
