Answer:

The liquid and the medal

Step-by-step explanation: "So the electrons start to move from one metal to the other through the liquid. This creates current" This is why i would check the liquid and the medal. if the experiemnt doesnt work then there must be something wrong with the current

Suppose a simple random sample of size nequals64 is obtained from a population with mu equals 88 and sigma equals 8. ​(a) Describe the sampling distribution of x overbar. ​(b) What is Upper P (x overbar greater than 89.7 )​? ​(c) What is Upper P (x overbar less than or equals 85.7 )​? ​(d) What is Upper P (87.35 less than x overbar less than 90.5 )​?

Answers

Answer:

a) \bar X \sim N (\mu, (\sigma)/(√(n)))

With:

\mu_(\bar X)= 88

\sigma_(\bar X)= 8

b) z=(89.7-88)/((8)/(√(64)))= 1.7

P(Z>1.7) = 1-P(Z<1.7) =1-0.955=0.0446

c) z =(85.7-88)/((8)/(√(64)))= -2.3

P(Z<-2.3) = 0.0107

d) z =(87.35-88)/((8)/(√(64)))= -0.65

z =(90.5-88)/((8)/(√(64)))= 2.5

P(-0.65<z<2.5)=P(Z<2.5)-P(Z<-0.65) =0.994-0.258 = 0.736

Step-by-step explanation:

For this case we know the following propoertis for the random variable X

\mu = 88, \sigma = 8

We select a sample size of n = 64

Part a

Since the sample size is large enough we can use the central limit distribution and the distribution for the sample mean on this case would be:

\bar X \sim N (\mu, (\sigma)/(√(n)))

With:

\mu_(\bar X)= 88

\sigma_(\bar X)= 8

Part b

We want this probability:

P(\bar X>89.7)

We can use the z score formula given by:

z = (\bar X -\mu)/((\sigma)/(√(n)))

And if we find the z score for 89.7 we got:

z=(89.7-88)/((8)/(√(64)))= 1.7

P(Z>1.7) = 1-P(Z<1.7) =1-0.955=0.0446

Part c

P(\bar X<85.7)

We can use the z score formula given by:

z = (\bar X -\mu)/((\sigma)/(√(n)))

And if we find the z score for 85.7 we got:

z =(85.7-88)/((8)/(√(64)))= -2.3

P(Z<-2.3) = 0.0107

Part d

We want this probability:

P(87.35 <\bar X< 90.5)

We find the z scores:

z =(87.35-88)/((8)/(√(64)))= -0.65

z =(90.5-88)/((8)/(√(64)))= 2.5

P(-0.65<z<2.5)=P(Z<2.5)-P(Z<-0.65) =0.994-0.258 = 0.736

The ratio of squirrels to chipmunks in the yard was 2:7. How many squirrels were in the yard if there were 49 chipmunks?Explain please.

Answers

Let the number of squirells be 2x and number of chipmunks be 7x ,



Given that number of chipmunks is 49, so

= > 7x = 49

= > x = 49 / 7

= > x = 7




So the number of squirells will be 2x = 2( 7 ) = 14

Dan will be 8X years next year. how old was Dan five years ago. give your answer in terms of X

Answers

If Dan is 8x years old next year then he must be 8x-1 years old this year
With the same logic, five years ago from this year, he must be 8x-1-5=8x-6

The answer should be 8x-6

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed? A: 4+4+4+4
B: 8+8+8+8
C: (-1)(4+4+4+4)
D: (-8)+(-8)+(-8)+(-8)

Answers

The correct answer is B. 8 + 8 + 8 + 8, OR 4*8
Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go, AND HE STOPS 8 TIMES, SO correct answer is 8*4 = 32 

Answer:The correct answer is actually D
