Answer:
y = - 8
Step-by-step explanation:
The given line passes through (-4, 4) and (4, -2)
The slope of this line will be given by: Change in y ÷ change in x
Slope = = =
The slope of the given line times the slope of the perpendicular line = -1
Let's say the slope of the perpendicular line is p
Then, × p = -1
p = -1 ÷ =
The perpendicular line passes through point (6, 0)
Taking another point (x, y) on the perpendicular line;
=
Cross multiplying this gives the equation of the perpendicular line to be:
y = - 8
Answer:
it would take around..a year and a half
Step-by-step explanation:
Answer:
87.5%
Step-by-step explanation:
Total parts = 8
Part 6 = 1
Parts not 6 = 7
P(not 6) = 7/8
<u><em>In %age:</em></u>
=> 87.5%
Answer:
Since both and , you can use a normal distribution to approximate the binomial distribution.
The mean is of 11.1 and the standard deviation is of 2.64.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Using the normal distribution to approximate the binomial distribution.
This is possible if:
A survey of U.S. adults found that 37% have been to court. You randomly select 30 U.S.
This means that
Test if it is possible:
Since both and , you can use a normal distribution to approximate the binomial distribution.
Mean and standard deviation:
The mean is of 11.1 and the standard deviation is of 2.64.
Using proportions, it is found that the average daily requirement for these adults is of 2080 calories.
--------------------
- Percentage problems are solved by proportions, using a rule of three.
- 1560 calories is 75% = 0.75 of the calorie requirement for many adults.
- How much is 100% = 1?
The rule of three is:
1560 calories - 0.75
x calories - 1
Applying cross multiplication:
The average daily requirement for these adults is of 2080 calories.
