Fractions that are greater than 0 but less than 1 are classified as proper fraction. A improper fraction is always 1 or greater than 1.

HELP FAST!!! MARKING BRAINLIEST!!!

faust18 [17]

Answer:

Well, I think this is correct:

Well, if we know that a and b are parallel, that means they have the same slope but different y-intercept. So, if c and a intersects, then c and b are bound to intercept, because when c intersects with a, it will also cross b, since it will be going in the same route...which will make it also intersect with b. (crossing.)

Sorry if I'm wrong.

Hope this helps! :)

At a large Midwestern college, 4 % 4% of the students are Hispanic. A random sample of 20 students from the college is selected.

oee [108]

Answer:

option a

Step-by-step explanation:

given that at a large Midwestern college, 4 % 4% of the students are Hispanic.

A random sample of 20 students from the college is selected.

We have each student is independent of the other to be hispanic

p = success = being hispanic = 0.04 while

q = failure = being non hispanic = 0.96

X - no of hispanics is thus binomial with p = 0.04 and n =20 (sample size)

Since X is binomial

Var(x) = npq = 0.768

Std dev (x) = Square root of variance = $\sqrt{0.768} \\=0.8764$

rounded off it gives 0.88

So option a is right

Last month, Belinda worked 160 hours at a rate of $10.00 per hour. If her employer retains 9% of her gross salary, is $1,500 a r

sleet_krkn [62]

We have been given that last month, Belinda worked 160 hours at a rate of $10.00 per hour.

Let us find amount earned by Belinda last month as:

$\text{Amount earned in 160 hours}=\$10\times 160$

$\text{Amount earned in 160 hours}=\$1600$

We are also told that Belinda's employer retains 9% of her gross salary. This means that Belinda's net income will be 91% of $1600. $(100\%-9\%=91\%)$ .
