Factor the perfect-square trinomial in y = (x2 + 2x + 1) − 1− 1.<br> y = (x + <br> )2 − 1 −1
dolphi86 [110]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y = ( {x}^{2}  + 2x + 1) - 1

y =  ({x + 1})^{2} - 1

y =  ({x + 1})^{2} -  ({1})^{2}

We're done now but I have something to tell...

##############################

Hint :

{a}^{2} -  {b}^{2}  = (a + b)(a - b)

##############################

y = ( \: (x + 1)  + 1)( \: (x + 1) - 1) \\

y = (x + 2)(x)

A recent journal article reported that college students tend to watch an average of 12 hours of television per week. Candice, a
Anna [14]

Answer:

A. Candice should reject the null hypothesis as the 95% confidence interval does not contain 12 hours

Step-by-step explanation:

Given that:

Average watch hour = 12

sample size = 79

The 95% Confidence interval lies between 7.60 and 11.37.

Thus, since the average watch of students in her school does not lie within the interval between 7.60 and 11.37, Candice should reject the null hypothesis.

Issouf claims that the scale factor is 1/2. which statement about his claim is correct?
love history [14]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

CB'=C'B'=2

B'B=6

CB=CB'+B'B=2+4=6

The scale factor of a figure is

k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}

k=\frac{C'B'}{CB}

k=\frac{2}{6}

k=\frac{1}{3}

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.

Descent, Inc., produces a variety of climbing and mountaineering equipment. One of its products is a traditional three-strand cl
Rainbow [258]

Solution :

Assuming $\sigma_1^2=\sigma_2^2$

We have to test

$H_0:\mu_1=\mu_2$

Against H_a: \mu_1 \neq \mu_2

Level of significance, $\alpha = 0.05$

$s_p=\sqrt{\frac{(n_1-1)s_1^2+ (n_2-1)s_2^2}{n_1+n_2-2}}$

$s_p=\sqrt{\frac{(25-1)(425)^2+ (20-1)(415)^2}{25+20-2}}$

   = 420.6107

Under H_0, the t-statistics is as follows:

$t=\frac{(\overline{x_1} - \overline{x_2})}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}} \sim $             $\text{t with }(n_1+n_2-2) \ DF$

$t=\frac{(7200-7087)}{(420.6107)\sqrt{\frac{1}{25}+\frac{1}{20}}}$

 = 0.90

DF = (25 + 20 - 2)

    = 43

P-value of the test = 0.375

Since the p value is more than 0.05, we fail to reject our null hypothesis.

There is no difference between then mean tensile strength of the ropes that is produced in the Bozeman and Challis.
