Answer:

∠ 2 = 104°

Step-by-step explanation:

Since the trees are parallel, then

∠ 2 and 76° are same- side interior angles and are supplementary, thus

∠ 2 + 76° = 180° ( subtract 76° from both sides )

∠ 2 = 104°

Two processes in a manufacturing line are performed manually: operation A and operation B. A random sample of 50 different assem

MArishka [77]

Answer:

3.06

Step-by-step explanation:

The correct answer is - 3.06

Reason -

For sample A :

mean, $\bar{x_{1} }$ = 8.05

Standard deviation, $\sigma_{1}$ = 1.36

Size, $n_{1}$ = 50

For sample B :

mean, $\bar{x_{2} }$ = 7.26

Standard deviation, $\sigma_{2}$ = 1.06

Size, $n_{2}$ = 38

Now,

$\bar{x_{1} }$ - $\bar{x_{2} }$ = 8.05 - 7.26 = 0.79

Standard deviation error, SE = √( $\sigma_{1}$ ²/ $n_{1}$ + $\sigma_{2}$ ²/ $n_{2}$ ) = 0.2580

Now,

Z-statistic = ( $\bar{x_{1} }$ - $\bar{x_{2} }$ )/ SE

= 0.79/0.2580

= 3.06

⇒Z-statistic = 3.06

Which rule describes the translation? t–3, –2(x, y) t–3, 2(x, y) t3, –2(x, y) t3, 2(x, y)

denis23 [38]

The rule that describes the translation is T3, -2 (x,y)

<h3>How to determine the translation rule?</h3>

The graph that completes the question is added as an attachment

From the attached graph, we have the following highlights:

Quadrilateral ABCD is translated 3 units right
Quadrilateral ABCD is translated 2 units down

This is represented as:

T3, -2 (x,y)

Hence, the rule that describes the translation is T3, -2 (x,y)

At a local fitness center, gym members pay $3 per workout with an annual membership fee of $140. Non-members pay $10 per workout

sleet_krkn [62]

Answer:

Yes the membership is worth it. If you have a membership you will pay $140 for the whole year. Then, it is $3 everytime you workout and if you plan on working out 2 times a month the total will be $72 dollars. So $72 + $140 is $212 yearly. If you don't get the membership you pay $20 a month because you will workout twice a month. So, 20 times 12 is $240. It may seem like it's not worth it but it actually comes out cheaper. So, yes I do think the membership is worth it.

Step-by-step explanation:

Hope you find this helpful. If you have questions feel free to ask.

[02.05] Marcie solved the following inequality, and her work is shown below: −2(x − 5) − 12 ≤ 4 + 6(x + 3) −2x + 10 − 12 ≤ 4 + 6

Nezavi [6.7K]

Hi there! Marcie made a mistake in the last step of the solving process.

Let's solve this problem step by step!
−2(x − 5) − 12 ≤ 4 + 6(x + 3)

First work out the parenthesis, which can for instance be done using rainbow method.

−2x + 10 − 12 ≤ 4 + 6x + 18
The parenthesis are worked out correctly. Remember that multiplying a negative by a negative gives you a positive.

Now we can collect the terms.
−2x − 2 ≤ 6x + 22

The terms are collected correctly.

Next up is subtracting 6x from both sides and adding 2 to both sides of the inequality.
−8x ≤ 24

This step is also correct.
Finally we must divide both sides of the inequality by -8 to find our answer. Be aware of the fact that the sign flips when dividing by a negative!

x ≤ −3
Mistake! Marcie forgot to flip the sign. Instead the answer should be $x \geqslant - 3$

~ Hope this helps you!
