Find the equation of a line passing through (-2,4) and ( 0,8)

1 answer:

5 0

Eqn of line: y = mx + c
where m is the gradient and c is the y intercept
gradient = (8-4)/(0-(-2)) = 4/2 = 2
thus y = 2x + c
sub (0,8) into this eqn
8 = 2(0) + c
c = 8
eqn of line: y = 2x + 8

In a genetics experiment on peas, one sample of offspring contained green peas and yellow peas. Based on those results, estimate

pashok25 [27]

Answer:

The probability of getting an offspring pea that is green is is 0.733

YES, the probability is reasonably close to the expected value of 3/4 (0.750)

Step-by-step explanation:

The formula for calculating the probability of an event is;

P = Favorable Outcome / Sample space

Let A be an event of getting an offspring green peas, B be an event of getting an offspring yellow peas and N be the total number of peas.

number of green peas in an offspring are 350

number of yellow peas in an offspring are 127

total number of peas are 477

So in the genetic experiment, the number of times event A occurs is 350 and the number times event B occurs is 127

Now the probability of getting an offspring pea that is green is

P = number of green peas / total number of peas

p = n(A)/N

p = 350/477

p = 0.733

So YES, the probability is reasonably close to 3/4 ( 0.750 )

The probability of getting an offspring pea that is green is is 0.733.

YES, the probability is reasonably close to the expected value of 3/4 (0.750)

Suppose A and B represent two different schools populations where A>B abd A and B must be greater than 0. Which of the follow

igor_vitrenko [27]

Hmm, one way we can do this is by assigning numbers to each

A=4 and B=3
A>B because 4>3

so

A. 2(A+B)=2(4+3)=2(7)=14
B. A+B^2=4+3^2=4+9=13
C. A^2+B^2=4^2+3^2=16+9=25
D. A^2-B^2=4^2-3^2=16-9=7

the largest is 25 so C
