Answer:

To calculate slope with any two given points the formula is y2 - y1 / x2 - x1. So to solve the problem just plug in the values: 7 - 1 / 3 - (-3), 6 / 6, the slope is 1

Answer:

$\frac{2}{3}$

Step-by-step explanation:

To find the slope, you need to find the $\frac{rise}{run}$ between two points.

$\frac{rise}{run}$ = $\frac{7-1}{3-(-3)}$

= $\frac{7-1}{3+3}$

= $\frac{6}{9}$

= $\frac{2}{3}$

Question 4 options: Find the mean and standard deviation for a binomial distribution with 680 trials and a probability of succes

lys-0071 [83]

Answer:

Mean for a binomial distribution = 374

Standard deviation for a binomial distribution = 12.97

Step-by-step explanation:

We are given a binomial distribution with 680 trials and a probability of success of 0.55.

The above situation can be represented through Binomial distribution;

$P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....$

where, n = number of trials (samples) taken = 680 trials

r = number of success

p = probability of success which in our question is 0.55

So, it means X ~ $Binom(n=680, p=0.55)$

Now, we have to find the mean and standard deviation of the given binomial distribution.

Mean of Binomial Distribution is given by;

E(X) = n $\times$ p

So, E(X) = 680 $\times$ 0.55 = 374

Standard deviation of Binomial Distribution is given by;

S.D.(X) = $\sqrt{n \times p \times (1-p)}$

= $\sqrt{680 \times 0.55 \times (1-0.55)}$

= $\sqrt{680 \times 0.55 \times 0.45}$ = 12.97

Therefore, Mean and standard deviation for binomial distribution is 374 and 12.97 respectively.

−10x + 6(x − 5) = 12x − 62

tankabanditka [31]

Answer:

$x=2$

Step-by-step explanation:

So we have:

$-10x+6(x-5)=12x-62$

Distribute:

$-10x+6x-30=12x-62$

Combine like terms:

$-4x-30=12x-62$

Subtract 12x from both sides:

$-16x-30=-62$

Add 30 to both sides:

$-16x=-32$

Divide both sides by -16:

$x=2$

And that's our answer :)
