Answer:

125 times.

Step-by-step explanation:

Prob(Heads) = 1/2.

Prob(Spinner lands on 2) = 1/4  ( as there are 4 sections on the spinner).

So the best prediction for the number of times this occurs in a 1000 trials

=  1/2 * 1/4 * 1000

= 1/8 * 100

= 125 times.

ser-zykov [4K]

Answer:

a) 91.4%

b) 37.6%

c) 26.8%

Step-by-step explanation:

For each of these, we'll get a z-score, then use our calculators to find the area using normalcdf (on TI-84, 2nd->VARS->2)

a)  z = (9-6.4) / 1.9 = 1.368

    normalcdf(-999,1.368) = .914 = 91.4%

b) z = (7-6.4) / 1.9 = .316

   normalcdf(.316,999) = .376 = 37.6%

c) normalcdf(.316,1.368) = .268 = 26.8%

Frank is 4 times as old as Lin. The difference in their ages is equal to Lin’s age plus 8. How old is each?
Minchanka [31]
Let Lin be x years old.
Lin = x
Frank = 4x

<span>The difference in their ages is equal to Lin’s age plus 8
</span>⇒4x - x= x + 8

Solve x:
4x - x= x + 8

Combine like terms:
3x = x + 8

Take away x from both sides:
2x = 8

Divide by 2 on both sides:
x = 4

Lin is 4 years old.
Frank is 4 x 4 = 16 years old.

Answer: Lin is 4 years old and Frank is 16 years old.
