Answer: please read the steps

Step-by-step explanation:

To calculate percentage the odds of pulling 2 yellow cards out of 30 is 2/30. now we turn the denominater into 100

100/30= 3.33...

3.33*2=6.66.. (round to nearest tenth)

now you have 6.7/100 which is

6.7% chance

(if you need more precise number its 6.667%)

A Snapshot in USA Today indicates that 51% of Americans say the average person is not very considerate of others when talking on

Sergeu [11.5K]

Answer:

The approximate probability is $P(X > 0.52) = P(Z > 0.2 ) = 0.42074$

Step-by-step explanation:

From the question we are told that

The population proportion of Americans that say the average person is not considerate of others when talking on a cellphone is p = 0.51

The sample size is n = 100

Generally because the sample size is sufficiently large the mean of this sampling distribution is

$\mu_{x} = p = 0.51$

Generally the standard deviation is mathematically represented as

$\sigma = \sqrt{ \frac{p(1 - p)}{n} }$

=> $\sigma = \sqrt{ \frac{ 0.51 (1 - 0.51)}{100} }$

=> $\sigma = 0.04999$

Generally the sample proportion is mathematically represented as

$\^ p = \frac{52}{100}$

=> $\^ p = 0.52$

Generally the probability that 52 or more Americans would indicate that the average person is not very considerate of others when talking on a cellphone is mathematically represented as

$P(X > 0.52) = P( \frac{X - \mu_{x}}{\sigma} > \frac{ 0.52 - 0.51}{0.04999} )$

$\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )$

=> $P(X > 0.52) = P(Z > 0.2 )$

From the z table the area under the normal curve corresponding to 0.2 to the right is

$P(X > 0.52) = P(Z > 0.2 ) = 0.42074$

How many times can 0.1 fit into 100?

ANTONII [103]

Answer:

1000 times

Step-by-step explanation:

To find out how many times 0.1 can fit into 100, we can just divide 100 by 0.1.

But, we first find out how many times can 1 fit into 100.

No. of times 1 fit into 100 = 100 / 1 = 100 times

Now we know 1 is 10 times of 0.1, so we multiply the above by 10,

so 100 * 10 = 1000 times.

Therefore 0.1 can fit into 100 a 1000 times.

pavit has a clock with a minute hand that extends to the clock's edge. The minute hand is 5 inches long. What is the circumferen

Eddi Din [679]

Answer:

The circumference of the clock is $10\pi\ in$

Step-by-step explanation:

we know that

The circumference of a circle (clock) is equal to

$C=2\pi r$

In this problem

The long of the minute hand is the radius of the circle

$r=5\ in$

substitute

$C=2\pi (5)=10\pi\ in$ -----> exact value of the circumference
