Answer:

Option C

Step-by-step explanation:

From the graph attached,

Slope of the line passing through two points A and B will be,

m = \frac{\text{Rise}}{\text{Run}}

   = \frac{12}{8}

   = \frac{3}{2}

Triangles having same ratio of Height and base (slope) will lie on the line graphed.

Option A

Slope pf the triangle  = \frac{44}{21}

\frac{3}{2}\neq \frac{44}{21}

Slope of the line ≠ Slope of the triangle

Therefore, triangle will not lie on the line.

Option B

Slope of the triangle = \frac{36}{12}=\frac{3}{1}

\frac{3}{2}\neq  \frac{3}{1}

Triangle will not lie on the line.

Option C

Slope of the triangle = \frac{30}{20}= \frac{3}{2}

Since, slope of the line = slope of the triangle

\frac{3}{2}= \frac{3}{2}

Triangle will lie on the line.

Option D

Slope of the triangle = \frac{52}{26}=\frac{2}{1}

But \frac{3}{2}\neq \frac{2}{1}

Therefore, triangle will not lie on the given line.

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts? graph going through negative
miv72 [106K]

Answer:

The function g(x) has a higher y-intercept.

Step-by-step explanation:

First function f(x):

Slope = (-1, - (-1) / -4 - -1) = 0

So its equation is y = -1.

The y-intercept is (0, -1).

Second function g(x):

Slope = (13-9)/ (6-4) = 2.

y - y1 = m(x - x1)  where m = slope and (x1, y1) is a point on the line, so we have:

y - 9 = 2(x - 4)

y = 2x - 8 + 9

y = 2x + 1.

So the y-intercept is (0, 1).

Simplify the following expression 2/5 + 4/3 over 3/5
madreJ [45]
This written out is:

2/5 + 4/3
------------
     3/5

Roughly, now first we need to change the denominators to all match up in order to properly solve this problem.

Both 5 and 3 go into 15, 5 goes into 15 3 times and 3 goes into 15 5 times. With that said, multiply the individual numerators by 5 and 3.

2/5 -> 2*3/15 -> 6/15
4/3 -> 4*5/15 -> 20/15
3/5 -> 3*3/15 -> 9/15

With this, we then add the top numerator of the overall problem:

26/15
------- | With this we now cross-multiply.
 9/15

26/15 * 15/9 = 390/135 | Now to simplify this.

135 goes into 390 twice, as 270. Subtract 390 by 270, leaving us with 120.

Meaning: 2 120/135 is the answer, but now to simplify. Divide 120 and 135 by 5 to lessen this.

24/27 | Divide this by 3 to get your most simplified answer.
8/9 | Leaving us with the answer of:

2 8/9

I hope this helps, have a great rest of your day! ^ ^

The fill weight of a certain brand of adult cereal is normally distributed with a mean of 920 grams and a standard deviation of
gulaghasi [49]

Answer:

The probability that it will weigh more than 904 grams = 0.9452

Step-by-step explanation:

Given -

Mean (\nu ) = 920 grams

Standard deviation (\sigma  ) =10

Let X be the weight of a certain brand of adult cereal

if we select one box of cereal at random from this population

The probability that it will weigh more than 904 grams =

P(X> 304) = P(\frac{X - \nu }{\sigma }> \frac{904 - 920}{10})

                   = P(Z> -1.6)    Putting ( Z = \frac{X - \nu }{\sigma } )

                   = 1- P(Z<  -1.6)  Using Z table

                   = 1 - .0548

                   = 0.9452

Pretend you are coaching a sports team—you pick the sport. What are some ways you would use matrices on the job?
gayaneshka [121]
<span>A matrix is basically a table of columns and rows. One way to use an array is to tabulate information concerning two variables, for example, sizes of shoes and person's height, or price of different kinds of vegetables over 12 months, etc. So for your problem, think of two variables that you can tabulate in your sports team. If you are out of ideas, read the sports page.</span>

Find the measure of an interior and an exterior angle of a regular 46-gon
trapecia [35]
For any polygon, the formula of the interior angle is 180 - 360/n where n is the number of sides of the polygon. The exterior angle is the supplementary angle of the interior angle. Hence when n is equal to 46, then interior angle is equal to 172.17 degrees and the exterior is equal to 7.83 degrees.
