what fraction of 45 m is 180 cm
Answer:
1/25
Step-by-step explanation:
45 meters is equal to 4500cm
4500 divide by 180 is 25
So, 180 is equal to one over 25

Better Business Bureau conducted survey of 3,765 randomly selected residents of Laradise and found that 60% of them feel the businesses in Laradise, are run by compliant individuals. Find the best point estimate of the proportion of all residents of Laradise who believe businesses are run by compliant individuals.
a. In the prompt above what population parameter are you being asked about?
i. Proportion
ii. Mean
iii. Standard Deviation/Variance
iv. None of the above
b. What is the best point estimate?
c. What is the critical value (zα/2) or (tα/2) that corresponds to a confidence level of 99%?
d. Find the margin of error E, show the formula, fill in the pieces.
e. Construct the 99% confidence interval.
Answer:
a
i. Proportion
b
Best point estimate is [tex]\^ p = 0.60[/tex]
c
[tex]z_{\frac{\alpha }{2} } = 2.58 [/tex]
d
[tex]E = 0.0206 [/tex]
e
[tex] 0.5794 < p < 0.6206 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 3765
The proportion that feel the businesses in Laradise, are run by compliant individuals is [tex]\^ p = 0.60[/tex]
Considering question a
The correct option is Proportion because in the prompt we are told to obtain the fraction of the total sample size that has a particular attribute (which their opinion of business in Laradise) and this is what a proportion represents
Considering question b
The best point estimate is [tex]\^ p = 0.60[/tex] because this proportion best defines the fraction of the sample size who feel the businesses in Laradise, are run by compliant individuals
Considering question c
Generally given that the sample size is large enough n > 30 , it then means that the distribution is approximately normal so
From the question we are told the confidence level is 99% , hence the level of significance is
[tex]\alpha = (100 - 99 ) \%[/tex]
=> [tex]\alpha = 0.01[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]z_{\frac{\alpha }{2} } = 2.58 [/tex]
Considering question d
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 2.58 * \sqrt{\frac{ 0.60 (1- 0.60 )}{ 3765} } [/tex]
=> [tex]E = 0.0206 [/tex]
Considering question e
Generally 99% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex] 0.60 -0.0206 < p < 0.60 + 0.0206[/tex]
=> [tex] 0.5794 < p < 0.6206 [/tex]

Solve the
equation:
18 + x = 1
Answer:
x=-17
Step-by-step explanation:
Subtract 18 on both sides
18-18+x=1-18
x=-17
Hope this helps :D
Please mark brainliest
Answer:
x = -17
Step-by-step explanation:
Subtract 18 from both sides to get X by itself.
18 + x = 1
x = 1 - 18
x = -17

what is (8+7 + 3.3) times ( 1/2) ^2
Answer & Step-by-step explanation: 4.58
PEMDAS:
Parenthesis first! (8 + 7 + 3.3) = 18.3
Exponents second! [tex]1/2^{2}[/tex] = 1/4 = 0.25
Multiply third and solve! 18.3 x 0.25 = 4.575
Round if needed! 4.575 = 4.58 = 4.6 = 5

Answer:
c
Step-by-step explanation:
Answer:
A 4/5
Step-by-step explanation:
Cosine of an angle is the adjacent side over the hypotenuse. Sin A = 36/45 = 4/5.

12 x 1/2
How do I solve that, and what’s the answer?
Answer:
The answer is 6
Step-by-step explanation:
12 divided by 2 is 6. If you have a fraction of 1/2, then its half of it. 6 is half of 12. :)
Answer: 6
Explanation:
You can multiply the numerator by the numerator and the denominator by the denominator.
The numerator of 12 is 12 and denominator of 12 is 1.
[tex]\frac{12}{1} *\frac{1}{2}=\frac{12}{2}[/tex]
Simplify this fraction and you get 6 over 1 or just 6.
You can also use common sense (not really).
You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.
The expression 50 can be simplified to
Answer:
25
Step-by-step explanation:
The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.
Subtract. Express your answer in simplest form.
