Noah painted 3/20 of a fence in 1/2 a day how many days will it take him to paint the entire fence
Answers
Answer:
approximately 7 days
Step-by-step explanation:
20 ÷ 3 = 6.6 repeating, round up to 7 days
Answer:
3days and 8hours
Step-by-step explanation:
he painted 3/20 in 1/2day then
3/20 painted for 1/2 day =12 hours so
1/20 was painted in 12/3=4 hours
since 20 /20 will be how long will be needed to paint the entire fence
20*4hour = 80hours which is (24*3)+8 that will make
3days and 8hours or
3and 1/3 days

The following list gives the number of public libraries in each of 11 cities. 7, 11, 8, 7, 8, 7, 8, 11, 8, 10, 7 Find the modes of this data set. If there is more than one mode, write them separated by commas. If there is no mode, click on "No mode."
Answers
Answer:
The mode are: 7, 8
Step-by-step explanation:
Given
[tex]7, 11, 8, 7, 8, 7, 8, 11, 8, 10, 7[/tex]
Required
Determine the mode
We start by arranging the given data in ascending order
The ordered data are:
[tex]7,7,7,7, 8,8,8,8, 10, 11, 11[/tex]
From the above data.
7 has a frequency of 4
8 has a frequency of 4
10 has a frequency of 1
11 has a frequency of 2
The data with the highest frequency is the mode.
We can see that 7 and 8 both have frequencies of 4
Hence, the mode are: 7, 8
Answer:
The mode are: 7, 8

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.4. The probability that there are more than 5 occurrences in ten minutes is:____.a. .0241.b. .0771.c. .1126.d. .9107.The random variable x satisfies which of the following probability distributions?
A. Normal.B. Poisson.C. Binomial
Answers
The options given don't correspond to the values in the question. The options are from another question where mean is 5.3 and the probability being looked for is for exactly 3 occurrences and 5 occurrences
Answer:
A) 0.6511
B) Poisson distribution
Step-by-step explanation:
We are given;
Mean: μ = 5.4 minutes
Now, we want to find the probability that there are more than 5 occurrences in ten minutes.
This will be written as;
P(x > 5) = 1 - P(x < 5)
P(x < 5) = P(x = 4) + P(x = 3) + P(x = 2) + P(x = 1) + P(x = 0)
We will use Poisson distribution for this. The formula is;
P(x) = [(e^(-μ)) × μ^(x)]/x!
P(0) = [(e^(-5.4)) × 5.4^(0)]/0! = 0.004517
P(1) = [(e^(-5.4)) × 5.4^(1)]/1! = 0.02439
P(2) = [(e^(-5.4)) × 5.4^(2)]/2! = 0.06585
P(3) = [(e^(-5.4)) × 5.4^(3)]/3! = 0.11853
P(4) = [(e^(-5.4)) × 5.4^(4)]/4! = 0.16
Thus;
P(x < 5) = 0.16 + 0.11853 + 0.06585 + 0.004517 = 0.3489
Thus;
P(x > 5) = 1 - P(x < 5) = 1 - 0.3489 = 0.6511
B) like seen from solution A above, we used Poisson distribution formula.
Thus, random variable x satisfies Poisson distribution

At Harry’s discount handware everything is sold for 20% less than the price marked .if Harry buys tool kits for $80 what price should he mark them of he wants to make 20% profit on his cost
Answers
20% of $80=16
so, the selling price=80+16=$96
Let, by the mark price of 20% profit=x
so, x-(20% of x)=96
or, x-x/5=96
or, x= (96*5)/4

For the following statement identifying the independent independent variable is the faster you drive your car the longer it will take to come to a complete stop
Answers
Answer: Driving Speed
Step-by-step explanation:
The Independent variable is the one that is being experimented on to see the effect it will have on the dependent variable.
The Independent variable is adjusted to different levels to see if a relationship exists between these adjustments and a change in the dependent variable.
In this scenario the independent variable would be the speed you drive your car whilst time taken to completely stop is the dependent variable because the speed is the variable being adjusted to see the time taken to completely stop the car.

worms are used to break down food waste and create a soil conditioning compost. Some worm populations double every 3 months. Suppose the formula y=2(2^x/3) represent the pounds of worms in a population after x months. If there are initially 2 pounds of worms, how many pounds of worms will there be in 1 year? If 2 pounds is approximately 2,000 worms, how many worms will there be after 1 yesr?
Answers
8,000 each three months the population is doubled so i figured that each three months there are 2000 more worms i multiplied 3 by 4 Because 3 x 4 is 12 and a year is 12 months, and got 8,000 by multiplying 2,000 by 4. Hope this helps
