Answer:
Reject Null Hypothesis given that P-value < ∝
Step-by-step explanation:
Applying the Five ( 5 ) step model and assuming ∝ = 0.05
First step : determine the Null hypothesis
H0 : Age and support for Anti-smoking = independent
Second step : Determine the alternate hypothesis
Ha : Age and support for Anti-smoking ≠ independent
Thirdly : Identify significance level ( ∝ ) = 0.05
4th step : Calculate the Test statistic and P-value
Chi-squared test = 36.1429 using excel function
P-value = 1 - CHISQ.DIST(36.1429, 1, TRUE) < 0.0001
finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that
P-value < ∝
How many times a particular number is a zero<span> for a given polynomial. For example, in the polynomial function f(x)=(x–3)4(x–5)(x–8)2, the </span>zero<span> 3 has </span>multiplicity<span> 4, 5 has </span>multiplicity<span> 1, and 8 has </span>multiplicity<span> 2. Although this polynomial has only three </span>zeros<span>, we say that it has seven </span>zeros<span> counting </span><span>multiplicity</span>
Answer:
2 : 9
Step-by-step explanation:
Put the given numbers in the expression and simplify:
bikes before : total bikes
= (bikes before) : (bikes before) + (bikes bought)
= 6 : (6 +21)
= 6 : 27
= 2 : 9

A question like this would do little to convince you ratios have some usefulness. There appears to be no point whatever to knowing the fraction of older bikes.

Ratios are used many places in the real world. Perhaps the ratios you encounter most frequently are tax rates.
If you spend any time cooking, you know that certain ratios of ingredients produce better taste and/or texture than other ratios, and you know that (generally) changing the quantity a recipe produces will involve changing all the ingredient amounts by the same ratio.
Finance, health, time, diet budgets are often specifies as ratios: 14% APR, 2.3 infant deaths per 1000 live births, 2 hours outside class for each hour in class, 25% of calories from fat, and so on.
Of course, chemistry is all about ratios. CO₂ and H₂O are perhaps some of the more important ratios in the world right now. These specific ratios of carbon, hydrogen, and oxygen atoms make substances that are both life-giving and life-threatening. Much study is directed at determining and maintaining appropriate ratios of these substances relative to others.
Answer:
No
Step-by-step explanation:
To find out if 2 is a solution, replace all the x's with 2.
4(2 - 1) - 3(2 - 2) =8
4(1) - 3(0) = 8
4 - 0 = 8
4 = 8
Nope! False! 2 is not a solution.
W=-L+P/2
subtract L to the other side and then diving everything by 2 to get W by itself
