Convert 5 3/4 to an improper fraction.The improper fraction would be 23/4
Answer:
-41/10, -42/10, -43/10, -45/10
Step-by-step explanation:
multiply with 10 in numerator and denominator in -5/1 and -4/1
-5×10/1×10 , -4×10/1×10
you will get,
-50/10 , -40/10
now u can find the four rational numbers
four rational no's: -41/10, -42/10, -43/10, -45/10
hope u understood:)
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.
Answer:
x=14 to make the pay equal.
Step-by-step explanation:
Okay so what I did here is kind of time-consuming and I'm sure there's a better way, but I used a calculator to substitute a lot of different numbers into the equation to make it equal, and when I got to 14, the equations both ended up as 625.
