Answer:

C.) y=-3/2x+3

Step-by-step explanation:

The y-intercept (where the line crosses y) is 3 = +3

The line goes down 3 and right 2 = -3 / 2

y = -3/2 + 3

Answer:

<CFD =62°

<AFB= 90°

Step-by-step explanation:

here you have a vertical angle, so to simply put it the answer on one side of the angle is the same answer for the opposite side of the angle. knowing this, angle <AFE is 62° and <CFD is on the opposite side making the angle the same(62°). the opposite angle of <AFB is <EFD which is 118° but both <AFB and <AFC equal 118° so you subtract 118° to <AFC degree which is 28° and you get 90°.

i hope this makes sense im not good at explaining. if anyone has a better explanation feel free to correct me.

Scott started his bank account with $150 and is spending $7 per day on lunch. The x-axis would be labeled:

Inessa [10]

The x axis is labeled as Number of days.

<h3 /><h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

let x be the number of days and y be money.

So, the equation is

y = -7x + 150.

Hence, the x axis is labeled as Number of days.

Using the normal approximation to the binomial, it is found that:

The mean of X is of 52 samples.
The standard deviation of X is of 4.2661 samples.
0.0017 = 0.17% probability that less than half without any traces of pesticide.

--------------------------------

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

Can be approximated to a normal distribution, with mean given by:

$E(X) = np$

And standard deviation of:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Normal probability distribution

Z-score formula is used, which, in a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

Each z-score has an associated p-value, which measures the percentile of measure X.

--------------------------------

65% of samples had no pesticide, thus $p = 0.65$
80 samples, thus $n = 80$

The mean of X is of:

$E(X) = np = 0.65(80) = 52$

The standard deviation of X is of:

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{80(0.65)(0.35)} = 4.2661$

Using the approximation and continuity correction, the probability is $P(X < 40 - 0.5) = P(X < 39.5)$ , which is the p-value of Z when X = 39.5. Thus:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{39.5 - 52}{4.2661}$

$Z = -2.93$

$Z = -2.93$ has a p-value of 0.0017, thus:

0.0017 = 0.17% probability that less than half without any traces of pesticide.
