5/6 divided by 3/7?
simple mi amigo!~
7* 5= 35
3*6= 18
= 35/18
= 1 17/18
Original:
<span>The width and length of a rectangle are consecutive odd integers
</span>so W = x and L = x + 2
<span>If the length is increased by 5 feet, then new L = x + 2 + 5 = x + 7
</span>
A = L x W
60 = (x + 7) x
60 = x^2 + 7x
x^2 + 7x - 60 = 0
(x - 5)(x + 12) = 0
x = 5 and x = -12
From here you have x = W = 5 ft and L = x + 2 = 5 + 2 = 7 feet
Area of original = 5 x 7 = 35
answer
<span>the area of the original rectangle: </span>35 ft^2
(6t-4) + (6t-4) + (6t-4) + (6t-4)
4(6t-4)
24t-16
Using the <u>normal approximation to the binomial</u>, it is found that there is a 0.994 = 99.4% probability that we will have enough seats for everyone who shows up.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- The binomial distribution is the probability of <u>x successes on n trials</u>, with <u>p probability</u> of a success on each trial. It can be approximated to the normal distribution with .
In this problem:
- 15% do not show up, so 100 - 15 = 85% show up, which means that .
- 300 tickets are sold, hence .
The mean and the standard deviation are given by:
The probability that we will have enough seats for everyone who shows up is the probability of at most <u>270 people showing up</u>, which, using continuity correction, is , which is the <u>p-value of Z when X = 270.5</u>.
has a p-value of 0.994.
0.994 = 99.4% probability that we will have enough seats for everyone who shows up.
