Answer: C & D

Step-by-step explanation:

A binomial experiment must satisfy ALL four of the following:

A fixed number of trials
Each trial is independent of the others
There are only two outcomes (Success & Fail)
The probability of each outcome remains constant from trial to trial.

A) When the spinner is spun three times, X is the sum of the numbers the spinner lands on.

→ #3 is not satisfied (#4 is also not satisfied)

B) When the spinner is spun multiple times ...

→ #1 is not satisfied

C) When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.

→ Satisfies ALL FOUR

A fixed number of trials = 4
Each trial is independent of the others = each spin is separate
There are only two outcomes = Not Odd & Odd
The probability of each outcome remains constant from trial to trial = P(X = not odd) = 0.50 for each spin

D) When the spinner is spun five times, X is the number of times the spinner lands on 1.

→ Satisfies ALL FOUR

A fixed number of trials = 5
Each trial is independent of the others = each spin is separate
There are only two outcomes = 1 & Not 1
The probability of each outcome remains constant from trial to trial = P(X = 1) = 0.17 for each spin

What is the sign of f on the interval -2

TEA [102]

Answer:

$f$ is sometimes positive and sometimes negative.

Step-by-step explanation:

$f(x)=(x-3)(x+2)(x+4)(x+4)(x-1)(2x-9)$

Take $x=-1\in(-2,\frac{9}{2})\ as-2$

$f(-1)=(-1-3)(-1+2)(-1+4)(-1-1)(-2-9)\\\\=(-4)(1)(3)(-2)(-11)\\\\=-264\\\\f(-1)$

Take $x=2\in(-2,\frac{9}{2})\ as\ -2$

$f(2)=(2,-3)(2+2)(2+4)(2-1)(2\times2-9)\\\\=(-1)(4)(6)(1)(-5)\\\\=120\\\\f(2)>0$

Hence $f(x)$ for $x=-1$ and $f(x)>0$ for $x=2$

So $f$ is sometimes positive and sometimes negative in the interval.

Choose the equation you would use to find the altitude of the airplane. tan70 = 0 tan70 = sin70 =

KonstantinChe [14]

The situation is represented by a drawing with a right triangle where an airplane is at the top corner, the elevation angle (opposite to the airplane) is 70°, the height (vertical leg) is x, and the adjacent leg (horizontal leg) to the 70° angle is 800.

Then, to find the height x, which is the opposite leg to the angle, you can use the tangent ratio, which is opposite leg divided by adjacent leg:

tan(x) = opposite leg / adjacent leg => tan(70°) = x / 800

Answer: tan(70°) = x / 800
