Answer:

135y/o

105years apart

Step-by-step explanation:

Assuming that every mother in the family has their child at 15, Jessica‘s great great great great great great grandma is 135 (45 +15years for every 'great')

Jessica is fifteen (fifteen years younger than her mom, who is 30), so she and her great great great great great great grandma are 105 years apart.

Find the zeros of the function. Enter the solutions from least to greatest.
Harman [31]

Answer:

  x = 5, x = 11

Step-by-step explanation:

Set f(x) = 0 and solve for x.

  0 = (x -8)² -9

  9 = (x -8)² . . . . . add 9

  ±√9 = x -8 . . . . . take the square root

  ±3 +8 = x . . . . . . . add 8

That is, ...

  x = 8 -3 = 5 . . . . lesser x

  x = 8 +3 = 11 . . . greater x

Solve x2-8x=3 by completing the square. which is the solution set of the equation
Mazyrski [523]

we have

x^{2}-8x=3

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2}-8x+16=3+16

x^{2}-8x+16=19

Rewrite as perfect squares

(x-4)^{2}=19

(x-4)^{2}=19\\ (x-4)=(+/-)\sqrt{19} \\ \\ x1=4+\sqrt{19} =8.359\\ x2=4-\sqrt{19} =-0.359

therefore

the answer is

x1=4+\sqrt{19} =8.359\\x2=4-\sqrt{19} =-0.359

Mark tosses a coin 25 times. What is the probability that it lands on heads exactly seven times?
mezya [45]

Answer:

1.43%

Step-by-step explanation:

we have that we can solve it by means of binomial, in this case m = 25. Also the probability of head is 50%. we need to know when it falls 7 times, therefore x = 7

the formula is:

P (x) = mCx * p ^ x * q ^ (m-x)

we know that p is 0.5 therefore q is equal to 0.5, replacing:

P (7) = 25C7 * 0.5 ^ 7 * 0.5 ^ (25-7)

P (7) = 25! / (7! * (25-7)!) * 0.5 ^ 7 * 0.5 ^ (25-7)

P = 0.0143

that is, the probability is 1.43%
