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
Answer:
0
Step-by-step explanation:
so p can be larger than -12 or can be -12
so the only answer there is 0
Answer:
Step-by-step explanation:
A line that is perpendicular to a reference line will have a slope that is the negative inverse of the reference line.
In this case, the reference line is y = -x - 1. It has a slope of -1. The negative inverse of this would be -(1/-1) = 1.
We can then write:
y = mx + b
y = 1x + b
To find b, enter the one given point that lines on the line, (-4,2).
y = 1x + b
y = 1x + b for (-4,2)
2 = 1(-4) + b
b = 6
The equation becomes y = x + 6

<h3>Order of Operations: </h3><h3>The steps used to evaluate a numerical expression:</h3><h3> 1) Simplify the expressions inside grouping symbols. ( ) , [ ]</h3><h3>2) Evaluate all powers. </h3><h3>3) Do all multiplications and/or divisions from left to right. </h3><h3>4) Do all additions and/or subtractions from left to right.
</h3><h3>PEMDAS represents the order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction</h3><h2>Example :</h2><h3>18 – (4 + 2) + (6 × 5) ÷ 3 = [Parentheses first]</h3><h3>Notice: There are no Exponents in this expression.
</h3><h3>18 – 6 + 30 ÷ 3 = [Multiplication/Division left to right next]
</h3><h3>18 – 6 + 10 = 22 [Addition/Subtraction left to right next]</h3><h3>When there are multiple grouping symbols, always work on the innermost grouping symbols first </h3><h3> ( ) = Parentheses [ ] = Brackets</h3><h3>Example: [(7 – 2) × 3] ÷ [4 + (2 ÷ 2)] – 7 × 0</h3><h3>Start with [(7 – 2)] and (2 ÷ 2) as these are the operations in the innermost grouping symbols.</h3><h3>
