The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain
Answers
Answer:
30%
Step-by-step explanation:
Key skills needed: Probability
1) There is a 70% chance of rain.
2) We need to find the chances against rain.
3) To do this, we need to use the fact that
70% + x = 100% (Since all the probabilities add up to 1 or 100%)
4) If you subtract 70% from both sides, x = 30%
5) This means the probability against rain is 30%.
Hope you understood and have a nice day!! :D

Step-by-step explanation:
1. Increase amount = 40-25=15 Increase percent = (15/25)×100%= 60%.
2.Increase amount = 30-15 = 15. Increase percent = ( 15/15)× 100% = 100%.
3. Increase amount= 50-18=32 Increase percent= (32/18) x100% = 177.77%
4. Increase amount= 80-22=58 Increase percent= (58/80) x 100% = 72.5% -----> 73% (when rounded of to the nearest 10's).
5. Increase amount= 18-16=2 Increase percent = (2/18)×100 %= 11.111...% -----> 11% (when rounded of to the nearest 10's).
6. Increase amount = 10-3=7 Increase percent= (7/10)×100% = 70%.
7. Increase amount = 100-85 = 15 Increase percent = ( 15/100) × 100% = 15%

You have two pieces of rope. One piece is of rope is 98 feet and the other is 56 feet. You need to cut the rope into equal lengths with non left over. What is the greatest possible lenth you can cut the rope so all peices will be the same
Answers
Answer:
14 feet
Step-by-step explanation:
We solve the above question by using the Greatest Common Factor method
We find the factors of 56 and 98
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The factors of 98 are: 1, 2, 7, 14, 49, 98
Then the greatest common factor is 14.
Therefore, the greatest possible length you can cut the rope so all pieces will be the same is 14 feet

If line SQ bisects angle RST, that means it splits it in half. This would make angles RSQ and QST equivalent.
So that means that angle RSQ would equal 26
Since the question is asking for angle RST (the whole angle), you would add both of the angles
26 +26 = 52

What is the length of the hypotenuse?
Answers
Answer:
The length of hypotenuse is 45 kilometers
Step-by-step explanation:
Assuming that given lengths are of perpendicular and hypotenuse, and the triangle is a right angled triangle
Perpendicular = P = 27 km
Base = B = 36 km
Hypotenuse = H = ?
We can use Pythagoras theorem for finding the length of hypotenuse
The Pythagoras theorem is given by:
[tex]H^2 = B^2+P^2[/tex]
Putting the values, we get
[tex]H^2 = (36)^2 + (27)^2\\H^2 = 1296 + 729\\H^2 =2025[/tex]
Taking square root on both sides
[tex]\sqrt{H^2} =\sqrt{2025}\\H =45[/tex]
Hence,
The length of hypotenuse is 45 kilometers

The mean housing price for an area is $135,000 with a standard of $45,000 but is not normally distributed. According to the Central Limit Theorem what would we need to make sure is true about our sample in order to use normal distribution
Answers
Answer:
A sample size greater than 30
Step-by-step explanation: The central limit theorem proffers the conditions necessary to obtain a normal or bell shaped distribution. It defines normal distribution in terms of mean, standard deviation and sample size. The sample size is a very important factor in determining the shape of a distribution.
Thus with a population having mean and standard deviation stated, in other to make use of or assume normal distribution, the sample size must be large. According tho the central limit theorem, a size of greater than 30 is deemed to be large enough. As the Same size increases, the sample mean converges to the value of the population mean.
