You cannot simplify 7/9 because it is already in simiplist form. It is the lowest they can be simplified.
Answer:
There is no enough evidence to reject the claim using a level of significance of 5%
Step-by-step explanation:
Let p be the true proportion of homeowners in Omaha who own a lawnmower. We want to test
vs (two-tailed alternative).
We have a large sample of size n = 500 and a point estimate for p is . The test statistic is given by
where is the standard error of when is true. The observed value is = 1.4064 which comes from a standard normal distribution. Because we want to use a level of significance of 5%, our rejection region is RR={z | z < -1.96 or z > 1.96} where -1.96 and 1.96 are the 2.5th and 97.5th quantiles respectively. Because 1.4064 does not belong to RR, we fail to reject the null hypothesis.
27, you multily eacg number by 3. 3*1=3, 3*3=9, 9*3=27, 27*3=81.
Rewrite the equation: 2y=x-6, y=x/2-3, so slope is 1/2 which is also the slope of the parallel line.
It will have the equation y=x/2+a where a is found by plugging in the given point: 4=-1+a, so a=5.
Therefore y=x/2+5. (This can also be written 2y=x+10 or x-2y+10=0)
Answer:
Step-by-step explanation:
Simplifying
4x + 2y = 18
Solving
4x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
4x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
4x + 0 = 18 + -2y
4x = 18 + -2y
Divide each side by '4'.
x = 4.5 + -0.5y
Simplifying
x = 4.5 + -0.5y
////////////
Simplifying
y = -2 + 9
Combine like terms: -2 + 9 = 7
y = 7
Solving
y = 7
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 7
