Suppose in a local kindergarten through 12th grade (k - 12) school district, 53 percent of the population favor a charter school for grades k through five. a simple random sample of 800 is surveyed. calculate the following using the normal approximation to the binomial distribution. (round your answers to four decimal places.)

(a) find the probability that less than 340 favor a charter school for grades k through 5.

(b) find the probability that 430 or more favor a charter school for grades k through 5.

(c) find the probability that no more than 390 favor a charter school for grades k through 5.

(d) find the probability that there are fewer than 375 that favor a charter school for grades k through 5.

(e) find the probability that exactly 400 favor a charter school for grades k through 5.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
