3. Jade is checking one of her zeros to a quadratic function. Her steps are shown. What must be true of this value?
Check = 2
0= (2)2 – 2(2) – 3
0= 4 - 4 - 3
0 -3
Answers
Answer:
Option C: since a false statement resulted, it means x = 2 is not a zero.
Step-by-step explanation:
We are told that She is checking the zeros of her quadratic function.
Now the zeros of a quadratic function f(x) are values of that make f(x) = 0. In order words they are basically the roots of the function or the x-intercept.
Now, she has tried x = 2 into her quadratic equation and it didn't yield zero.
Since it yielded -3 and not 0, it means 2 is not a zero of the quadratic function.

Answers
Answer:
If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and –1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and –6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.

Assume that a procedure yields a binomial distribution with a trial repeated
n=5 times. Use some form of technology to find the probability distribution given the probability p=0.156 of success on a single trial.
Answers
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 5, p = 0.156, and q = 0.844.
r = 0, P = ₅C₀ (0.156)⁰ (0.844)⁵⁻⁰ = 0.428
r = 1, P = ₅C₁ (0.156)¹ (0.844)⁵⁻¹ = 0.396
r = 2, P = ₅C₂ (0.156)² (0.844)⁵⁻² = 0.146
r = 3, P = ₅C₃ (0.156)³ (0.844)⁵⁻³ = 0.027
r = 4, P = ₅C₄ (0.156)⁴ (0.844)⁵⁻⁴ = 0.002
r = 5, P = ₅C₅ (0.156)⁵ (0.844)⁵⁻⁵ ≈ 0

-8x + 40 greater than -16
Answers
Answer:
x > 7
Step-by-step explanation:
First, you start off with :
-8x + 40 > -16
Then you subtract 40 on both sides.
You get -8x > -56.
Next, you divide -8 on both sides. Cancel out the -8/-8.
After dividing, you have x > 7
Therefore the answer is x > 7!
