Answer:

x = 5

Step-by-step explanation:

"bisects" means cutting in half.

so, BX is cutting the angle ABC in half. and "half" means that both created parts are equally big.

and so we know

5x = 3x + 10

now we simply solve for x.

2x = 10

x = 5

Does the sample provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package? Gro

kirill115 [55]

Answer:

As probability of that happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.

Step-by-step explanation:

For a normal distribution Z-score

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

Given that :

the mean ( $\mu$ ) = 35.6

standard deviation ( $\sigma$ ) = 5.2

sample size (n) = 35

standard error: $\sigma_x = \frac{\sigma}{\sqrt{n}}$

$\sigma_x = \frac{5.2}{\sqrt{35}}$

$\sigma_x = 0.879$

The probability that a random sample of 35 bags has a mean weight of 33.6 grams or less is :

P(X<33.6) = P(Z < - 2.28)

= 0.0114

Conclusion:

As probability of the happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.

Factor by grouping : xy + 6y - 2x - 12 (if you don't know the answer don't comment)

<h3> Hey There today we will solve your problem</h3>

First we will factor out $y$ from $xy+6y$ which gives us $y(x+6)$
