Answer:
The test statistic is z = -2.82.
Step-by-step explanation:
A marketing research firm believes that more than half of adults drink mostly either regular or diet soda.
This means that the null hypothesis is:
The alternate hypothesis is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
0.5 tested at the null hypothesis:
This means that:
Gallup took a nationally representative sample of 2027 adults and asked them about their soda consumption. The survey shows that 950 of those surveyed drink mostly either regular or diet soda.
This means that
Test statistic:
The test statistic is z = -2.82.
Verticalset the denominator of the function equal to zero and solve for 'x', x is the vertical asymptote.Horizontalsubtract the amount of x's in the numerator from the number of x's in the denominator, then do one of the four things to find y: and if the answer is negative, then y=0 does that help any?if the answer is 0, then y= a/b (ax/bx)<span>If the answer is greater than positive 1, then there is no horizontal asymptote
</span>ObliqueIf the answer is 1, then it is oblique. use long division with the denominator as the divisor of the overall function given (not the fraction) and y= ax+/- b
Does this help at all

Answer:
its associative property
Step-by-step explanation:
2+d=2+d
d=2
When a sign has the underline, it means it is also equal to.
for example,
x
10
so the solution for "x" is greater than or equal to 10
hope this helps!
