Answer:

(-4, -26) / Intersection

Step-by-step explanation:

When we graph the system of equations, we need to find the point where the line intersects to find the solution.

The graph below shows both lines being graphed and the intersection point of the line.

As we can see, the intersection occurs at point (-4, -26). Thus, this is the solution or classification for the system.

Best of Luck!

Answer:

Intersecting

Suppose that the good professor had instead taken a randomized and enumerated list of all students in the UC system and randomly
Vadim26 [7]

Answer: Systematic sampling

Step-by-step explanation:

  • A <em>systematic sampling method</em> is a technique of random sampling in which participants for the study are selected in a systematic way by using a fixed periodic interval <em>k</em> from the entire population .

Here , Professor had taken a randomized and enumerated list of all students in the UC system and randomly selected a starting point on that list.

He then selects that student for inclusion in the sample, and every 25th student thereafter.

That clearly shows that he is following the systematic sampling technique, where <em>k= 25</em>.

Hence, the sampling design he used = systematic sampling

What is the length of SR?<br><br> 9 units<br> 12 units<br> 15 units<br> 18 units
Leviafan [203]

we know that

In the right triangle RSQ

cos\ S=\frac{RS}{SQ}

cos\ S=\frac{RS}{25} ------> equation 1

In the right triangle RST

cos\ S=\frac{ST}{RS}

cos\ S=\frac{9}{RS} ------> equation 2

equate equation 1 and equation 2

\frac{RS}{25}=\frac{9}{RS}\\ \\ RS^{2} =25*9\\ \\ RS=\sqrt{225} \\ \\ RS=15\ units

therefore

the answer is

the length of SR is 15\ units

Can you guys help me out!! Also can y’all show the work!
Lelechka [254]

Answer:

233.3 cubic units

Step-by-step explanation:

Volume of a pyramid

=  \frac{1}{3} × base area × height

The volume of the pyramid

=  \frac{1}{3}  \times (10 \times 10) \times 7

= \frac{1}{3}  \times 100 \times 7

= 233.333...

= 233.3 cubic units (rounded to the nearest tenth)
