A coefficient is just a number directly next to a variable. A constant is also a number but without any variables.When they say "like terms in math", you are just pairing the coefficients together and the variables (letters together).

For example:

4b+7b+5

B is a variable (letter). And 4b and 5b are like terms because they both have the variable 'b'. 5 has no like term because it is the only constant.

Your answer would be 11b+5.

Because you will add "like terms", 4b and 7b both have the same variable and they both have coefficients which are 4 and 7 so, I simply added them to get 11b.

A selective university advertises that 96% of its bachelor’s degree graduates have, on graduation day, a professional job offer

OLEGan [10]

Answer:

The probability is $P( p < 0.9207) = 0.0012556$

Step-by-step explanation:

From the question we are told

The population proportion is $p = 0.96$

The sample size is $n = 227$

The number of graduate who had job is k = 209

Generally given that the sample size is large enough (i.e n > 30) then the mean of this sampling distribution is

$\mu_x = p = 0.96$

Generally the standard deviation of this sampling distribution is

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

=> $\sigma = \sqrt{\frac{0.96 (1 - 0.96 )}{227} }$

=> $\sigma = 0.0130$

Generally the sample proportion is mathematically represented as

$\^ p = \frac{k}{n}$

=> $\^ p = \frac{209}{227}$

=> $\^ p = 0.9207$

Generally probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is mathematically represented as

$P( p < 0.9207) = P( \frac{\^ p - p }{\sigma } < \frac{0.9207 - 0.96}{0.0130 } )$

$\frac{\^ p - p}{\sigma } = Z (The \ standardized \ value\ of \ \^ p )$

$P( p < 0.9207) = P(Z< -3.022 )$

From the z table the area under the normal curve to the left corresponding to -3.022 is

$P(Z< -3.022 ) = 0.0012556$

=> $P( p < 0.9207) = 0.0012556$

I need help someone look at the picture

Natalka [10]

Answer:

Step-by-step explanation:

The outlier here is greatly above all of the others, the mean is the sum of all of the numbers/the amount of numbers. So, if we exclude the outlier, the sum of all of the numbers would decrease
