Answer:
The null and alternative hypothesis in symbols would be:H0:μ=0.9
H1:μ≠0.9,
The null hypothesis in words would be:_____________.
1. The proportion of all people that prefer Trydint gum is 0.9
Step-by-step explanation:
The Null hypothesis should always be precise such as the given coin is biased. The null hypothesis is assigned a numerical value.
For example the average height of all students in a college is 62 inches. Symbolically it is written as :H0:μ=62
An alternative hypothesis is any other hypothesis which we accept when the null hypothesis is rejected.If the null hpothesis of the height of students is :H0:μ=62 then alternative hypothesis is H1:μ≠ 62
Answer: Choice C) Multiplication property of inequalityThe rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.
Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips
Example 2:
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip
Similar rules apply to a > b,
![a \le b](https://tex.z-dn.net/?f=a%20%5Cle%20b)
and
6 = 15w + 75w - 4
6 = 90w - 4 <em>added like terms (15w + 75w)</em>
10 = 90w <em>added 4 to both sides</em>
10/90 = w <em>divided both sides by 90</em>
1/9 = w <em>simplified fraction</em>
Answer: 1/9
