43% of 300 is what number

Stells [14]

129
Find 10% (30) then times by 4 to find 40% (120)
Find 1% (3) then times by 3 to find 3% (9)
Add the 40% to the 3% (120 + 9)
= 129

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

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

Somebody help thanks

slamgirl [31]

Really simple, All you have to do is find out how many meters are in a kilometer, which is 1000 meters, and then you have to multiply 1000 with 190 which is 190000. Hope i helped!
