Can someone help with this question below?
Oxana [17]

Answer:

C = 106.76 cm

Step-by-step explanation:

In the diagram, we are given the diameter (d), which is 34 cm.  Using the formula you are given, we know circumference is 3.14 × d

C = 3.14 × d

C = 3.14 × (34)

C = 106.76 cm

The circumference is around 106.76 cm

Serggg [28]

Answer:

The claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.

Step-by-step explanation:

Since an online health and medicine company claims that about 50% of Internet users would go to an online sight first for information regarding health and medicine, and a random sample of 1318 Internet users was asked where they will go for information the next time they need information about health or medicine; 606 said that they would use the Internet, to test the claim that less than 50% of Internet users get their health questions answered online, the following calculation must be performed:

1318 = 100

606 = X

606 x 100/1318 = X

60600/1318 = X

45.978 = X

Therefore, the claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.

Answer:

x is 6 because

y is 30

p is 120

Step-by-step explanation:

60 degrees and 10x are the same and 6×10 = 60

(4y) and 60 degrees must equal 180 so y has to be 30

(4y) and p are the same

The number of rookie cards in a variety pack of baseball cards is normally distributed with a mean of 3 cards and the standard d
Sergio039 [100]

Answer:

z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163

z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163

P(-3.163

P(-3.163

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10

Step-by-step explanation:

Let X the random variable that represent the number of rookie cards of a population, and for this case we know the distribution for X is given by:

X \sim N(3,1)  

Where \mu=3 and \sigma=1

We select a sample size of n = 10 variety packs and we want to find this probability:

P(2

We can use the z score formula given by:

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

If we apply this formula to our probability we got this:

We can find the z score for 2 and 4 and we got:

z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163

z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163

So we can find the probability with this difference

P(-3.163

And using the normal standard distirbution or excel we got:

P(-3.163

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
