Answer:

a) The measure of the reference angle is 45°

Step-by-step explanation:

Reference angle:

$\sf \dfrac{7\pi }{4} \ is \ in \ the \ fourth \ quadrant.\\\\ \text{Reference angle = 2$\pi - \theta$}\\$

$\sf =2\pi -\dfrac{7\pi }{4}\\\\ =\dfrac{8\pi }{4}-\dfrac{7\pi }{4}\\\\= \dfrac{\pi }{4}\\\\=\dfrac{180}{4}\\\\$

= 45°

Answer:

See below

Step-by-step explanation:

As the other answerer posted : the reference angle is 45 °

<u>ALSO</u> tan = -1 and sin = - sqrt(2) / 2

Which of the following graphs shows the solution for the inequality y - 4 > 2(x + 2)?

Murljashka [212]

Answer:

D. Graph C

Step-by-step explanation:

y - 4 > 2(x + 2)

y > 2x + 4 + 4

y > 2x + 8

Let y = 2x + 8, Then

X-intercept (0, 8)

Y-intercept (-4, 0)

Since the inequality sign is > we use broken line.

to test the direction, take (0, 0)

y > 2x + 8

0 > 0+ 8

0 > 8 Which is false

so, the answer will be above the broken line

Figure A is a scale image of Figure B. What is the value of x?

Snezhnost [94]

Answer:

x = 5.4

Step-by-step explanation:

since the figures are scaled factors of each other then they are similar.

the ratios of corresponding sides are therefore in proportion, that is

$\frac{x}{7.2}$ = $\frac{3}{4}$ ( cross- multiply )

4x = 21.6 ( divide both sides by 4 )

x = 5.4

Zinnia normally earns $13 per hour working as a tutor but she earns $20 per hour for every hour she works over 40 in one week la

masya89 [10]

Answer:

Step-by-step explanation:

Zinnia works 40 hours and earns $13 for each of those 40 hours, putting her at 40 * 13 = $520.

Then she works 9 hours over and earns$20 for each of those 9 hours, putting her at 9 * $20 = $180.

Adding those 2 together gives Zinnia a grand total of $700 in that week.

An experiment is being planned to compare the effects of several diets on the weight gain of beef cattle, measured over a 140-da

bezimeni [28]

Answer:

Part (A) 16 cattle should be put on each diet in order to achieve a sufficiently small standard error.

Part (B) No, the required number of cattle should not double.

Step-by-step explanation:

Consider the provided information.

The standard error of the mean for each diet should not exceed 5kg.

Therefore, sample mean is = $\sigma_{\bar x}\leq 5$

Part (A)

The population standard deviation of weight gain is guessed to be about 20kg on any of the diets,

From the above $\sigma=20$

It is given that $\sigma_{\bar x}\leq 5$

As we know $\sigma_{\bar x}=\text{sd(sample mean)} = \frac{\text{(population standard deviation)}}{\sqrt{n}}$

Thus,

$\frac{20}{\sqrt{n}}\leq 5$

$\frac{20}{5}\leq \sqrt{n}$

$4\leq \sqrt{n}$

$16\leq n$

16 cattle should be put on each diet in order to achieve a sufficiently small standard error.

Part (B) If the guess of the s.d is doubled, to 40kg, does the required number of cattle double?

From the above $\sigma=40$

It is given that $\sigma_{\bar x}\leq 5$

Thus,

$\frac{40}{\sqrt{n}}\leq 5$

$\frac{40}{5}\leq \sqrt{n}$

$8\leq \sqrt{n}$

$64\leq n$

64 cattle are required, which is not the double of 16.

Hence, No, the required number of cattle should not double.
