Slope is 2: y intercept is 7

-4x + 2y = 14

2y = 4x + 14

y = 4x/2 + 14/2

y = 2x + 7 comparing to y = mx + c, slope = m, and y intercept = 7

m = slope = 2, y intercept = c = 7

How to subtract fractions

frosja888 [35]

You need to first make denominator in the fractions you have equal, then simply subtract numenators.

example:
2/3 - 1/2
first step is to make denominators equal.
for this example, the denominator will be equal to 6 which is 2x3
so, 2/3 = 4/6 and 1/2 = 3/6
so, the expression now becomes:
4/6 - 3/6
simply subtract numenators and the denominator will be 6 as well.
4/6 - 3/6 = 1/6

another example:
3/4 - 1/2
here the denominator can be equal to 4 in all terms
1/2 = 2/4
so, the new expression is now:
3/4 - 2/4 = 1/4

Marianna [84]

Answer:

11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they received a pneumococcal vaccination, or they did not. The probability of an adult receiving a pneumococcal vaccination is independent of other adults. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

70% of U.S. adults aged 65 and over have ever received a pneumococcal vaccination.

This means that $p = 0.7$

20 adults

This means that $n = 20$

Determine the probability that exactly 12 members of the sample received a pneumococcal vaccination.

This is P(X = 12).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{20,12}.(0.7)^{12}.(0.3)^{8} = 0.1144$

11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.

I need to find the slope and y-intercept of this equation. I also need to convert it to slope intercept form. The equation is 3x

USPshnik [31]

Answer:

slope=-1/2

y intercept =-2

Step-by-step explanation:

what u have to do is get y on 1 side and 3x on the other, so take away 3x from both sides which leaves you with 6y = -3x -12. then divide both sides by 6 to get y on it's own so you have y= -1/2x -2. this formula is y=mx+c the m is always the slope and the c is always the y intercept
