Answer:

B.  \frac{3}{16} and \frac{3}{8}

Step-by-step explanation:

From the given figure, we see that,

Every partition is of length \frac{1}{16}.

So, we get that,

\frac{1}{16} contains 4 data points.

\frac{3}{16} contains 1 data point.

\frac{6}{16} contains 1 data point.

\frac{8}{16}=\frac{1}{2} contains 2 data points.

\frac{10}{16} contains 2 data points.

\frac{12}{16} contains 1 data point.

Since, the largest gap between two data points is \frac{2}{16} which occurs between the points \frac{3}{16} and \frac{6}{16}=\frac{3}{8}

<h3>Hence, B is the correct option.</h3>

What is the solution to the following system of equations?<br><br> x+y=5<br> x-y=1<br> step by step
Andreas93 [3]
x+y=5
-x -x

Equals:

y=-x+5

Now you have:

y=-x+5
x-y=1

Insert -x+5 into y

x-x+5=1

Combine like terms

2x+5=1

Subtract 5.

2x=-4

Divide 2.

Answer: x=-2

Answer: 3:2

Step-by-step explanation:

the base ratio of unused tape to used tape is 24:16.

then we have to simplify,

both 16 and 24 can be divided by eight,

24 divided by eight is 3

16 divided by eight is 2

therefore, our simlpified ratio is 3:2

hope this helped! <3

Answer:

  • b
  • b
  • a
  • b

Step-by-step explanation:

There are a few algebraic, geometric, and trig relations you are expected to remember. These come into play in this set of questions.

  • vertex form for equation of a parabola: y = a(x -h)² +k, has vertex at (h, k)
  • Sine Law relates triangle sides and their opposite angles: a/sin(A) = b/sin(B)
  • Cosine Law relates triangle sides and the angle between two of them: c² = a² +b² -2ab·cos(C)
  • SOH CAH TOA reminds you of trig relations in a right triangle
  • relationships of corresponding sides and angles in congruent and similar triangles: angles are congruent; sides are congruent or proportional.

When solving any problem, the first step is to understand what is being asked. The second step is to identify the relevant information and relationships that can help you answer.

<h3>1)</h3>

You are asked for the equation of a parabola with a given vertex. The vertex form equation will be useful. We can assume a scale factor ('a') of 1.

For vertex (h, k) = (1, -4) and a=1, the vertex form equation is ...

  y = a(x -h)² +k

  y = 1(x -1)² +(-4)

  y = (x -1)² -4

<h3>2)</h3>

You are given 3 sides and want to find an angle. The useful relation in this case is the Cosine Law. (If you wanted to use the Sine Law, you would already need to know an angle.)

<h3>3) </h3>

The mnemonic SOA CAH TOA reminds you that the cosine relation is ...

  Cos = Adjacent/Hypotenuse

The side adjacent to angle C is marked 4; the hypotenuse is marked 5. The desired ratio is ...

  cos(C) = 4/5

<h3>4)</h3>

The measure x is also the measure of side AB. The similarity statement lists those letters as the first two. It also lists the letters DE as the first two. The other given side in ΔABC is BC, corresponding to side EF in the smaller triangle. Corresponding sides are proportional, so we have ...

  AB/DE = BC/EF

  x/6 = 10/4

We can find the value of x by multiplying this equation by 6:

  x = 6(10/4) = 60/4

  x = 15

Please note that BC is the shortest side in ΔABC. This means x > 10. There is only one such answer choice. (No math necessary.)
