Answer:
)
Step-by-step explanation:
From the diagram, 
.
The side of the triangle with length 11.9 is adjacent to the given angle.
We also know the hypotenuse to be 14.5 units.
We therefore use the cosine ratio to get;
We take the inverse cosine of both sides to get;
)
Answer:
+1+3
Step-by-step explanation:
1 +1=2
2+3=5
5+1=6
6+3=9
Answer:
1
Step-by-step explanation:
We know that the mathematics test scores are normally distributed with mean μ=82 and standard deviation σ=8.
We know that the central limit theorem states that a selected sample from a normal distribution with mean μ and standard deviation σ is also normally distributed with mean μxbar and standard deviation σxbar.
Also , the sample mean of sampling distribution is μxbar=μ, where μ is population mean.
The standard deviation of sampling distribution is σxbar=σ/√n where n is the sample size and σ is population standard deviation.
The given sample size=n=64.
So, the required standard deviation of sampling distribution is
σxbar=σ/√n
σxbar=8/√64
σxbar=8/8
σxbar=1.
Ok nice answer…… well done
Answer:
none of them are true, but if you could re copy and paste and delete all of the spaces, I can make 100% sure because I could've did something wrong with it looking like this.
24.8/ 102= 0.243
34.65/ 1,000= 0.03465
193.5/100= 1.935
6.24/10= 0.624
160.4/ 102= 1.5725
these are the equations in the problem with their actual answers, none of them match the ones provided
