Answer: length = 4.5 m, width = 3 m
Step-by-step explanation:
When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.
length = 3 * 1.5 = 4.5 m
width = 2 * 1.5 = 3 m
Answer:
It would not be reasonable to say that more than half of the people with this disease would improve if they used the new drug
Step-by-step explanation:
Data provided in the question:
Sample size, n = 1000
Number of people improved when they used the drug = 510
Thus,
Probability that Number of people improved when they used the drug
= 510 ÷ 1000
= 0.510
Now,
margin of error, E = 
= 
= 0.032 = 3.2%
Therefore,
Portion of 0.510 is likely to lie in the 3.2% of the actual value of population
And,
The lower portion can be as small as p - E
= 0.510 - 0.032
= 0.478 i.e 47.8% of the sample
Hence,
It would not be reasonable to say that more than half of the people with this disease would improve if they used the new drug
13 is your answer my friend!
Answer:
dogs = 79
dats = 90
fish = 183
Step-by-step explanation:
let the total number of dogs owned be x
no. of cats owned = x+11
no. of fish owned = x+11+x+14= 2x+25
hence,
2x+25+x+11+x=352
4x=316
x=316/4= 79mil
no. of cats owned = 79 + 11 = 90
no. of fish owned = 2(79)+25=183
Answer:
The weigh of yellow potatoes that James bought is 8330 kilograms .
Step-by-step explanation:
Given as :
The weigh of red potatoes that James bought = 245 kilograms
The weigh of yellow potatoes that James bought = 34 times the weight of red potatoes
Let The weigh of yellow potatoes that James bought = x kg
Now, According to question
∵The weigh of yellow potatoes that James bought = 34 times the weight of red potatoes
i.e The weigh of yellow potatoes that James bought = 34 × The weigh of red potatoes that James bought
Or, x = 34 × 245 kg
Or, x = 8330 kg
So, The weigh of yellow potatoes that James bought = x = 8330 kg
Hence, The weigh of yellow potatoes that James bought is 8330 kilograms . Answer
