Answer:
-5/3, or in decimal form, -1.666.
Step-by-step explanation:
a. -146 (3k+5) --- distribute the -146 to "3k" and "+5."
b. -438k - 730 = 0 --- get the variable k to one side of the equation.
c. -438k=730 --- divide by -438 on both sides.
d. the answer you get is 730/-438, which, in simpler terms, is -5/3, or -1.666.

Answer:
In the equation y = mx + b for a straight line, the number m is called the slope of the line
Step-by-step explanation:
Answer:
Since the calculated value of z= 1.6279 does not fall in the critical region Z ≥ ±1.96 we conclude that there is no difference between the population variance and the sample variance.
Step-by-step explanation:
The data given is
Population mean μ= $ 7.18
Population variance= σ²= 3.81
Population Standard Deviation = √σ²= √3.81= 1.952
Sample Mean= x`= $ 8.02
Sample Standard Deviation =s = $ 2.08
Sample Size = 15
Significance Level = ∝= 0.05
The null and alternate hypotheses are
H0: σ1=σ2 against the claim that Ha: σ1≠ σ2
where σ1 is the population variance and
σ2 is the sample variance
The rejection region is Z ≥ ±1.96 for two tailed test at ∝= 0.05
The test statistic z is used
z= x`- μ/ σ/√n
Putting the values
Z= 8.02-7.18/1.952/√15
z= 0.84/0.51599
z= 1.6279
Since the calculated value of z= 1.6279 does not fall in the critical region Z ≥ ±1.96 we conclude that there is no difference between the population variance and the sample variance.
So the problem ask to find and convert the area into square meters. So to convert is you must do the cross multiplication process that could cancel out unit and made the answer into a square meter, so the answer would be 1. x10^-12m^2. I hope you are satisfied with my answer and feel free to ask for more
"The quantity of price measured in dollars depends on the quantity of time measured in minutes" is an example that best defines the two quantities that are measured to find the call rate of a cell phone company.
