So, you're going to write an addition or subtraction fact, like 20 - 9 = ? Then you are going to explain a way that you would get the answer, like 'I draw 20 little circles, I erase nine of them, I only have eleven circles left, so the answer is eleven'

Answer: Divide using synthetic division. If the remainder is 0, then x+2 is a factor.

x+2 is not a factor.

I put your question into a website, I don't know if that will help you but that's the best I can do, I don't even know the answer

With food prices becoming a great issue in the world; wheat yields are even more important. Some of the highest yielding dry lan

Answer:

Option E) 61.6

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 bushels per acre

Standard Deviation, σ = 30 bushels per acre

We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X>x) = 0.90

We have to find the value of x such that the probability is 0.90

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 100}{30})=0.90$

$= 1 -P( z \leq \displaystyle\frac{x - 100}{30})=0.90$

$=P( z \leq \displaystyle\frac{x - 100}{30})=0.10$

Calculation the value from standard normal table, we have,

$P(z$

$\displaystyle\frac{x - 100}{30} = -1.282\\x = 61.55 \approx 61.6$

Hence, the yield of 61.6 bushels per acre or more would save the seed.

Determine the quadratic equation in standard form of a parabola with a zero at x=5 and vertex ar (-3, 32). start with factored f

elena-s [515]

Answer:

see image...

start with Graphing Form: y = a(x-h)²+ k

knowing that h is the x value (negative of it) of the vertex , and k is the y value of the vertex

Graphing Form Equation: y = a(x+3)²+32

you are also given that when the x value is 5 the y value has to be 0

0 = a(4)^2 + 32

a has to be - 1/2
