What is the perimeter of a triangle with vertices at (2, 3) (4, -1) and (-1, -5)?

Answer:

Step-by-step explanation:

The correct answer in this case would be A. There is only 1/8th percent chance of the spinner landing on 4.

There are 8 sections in the circle.  So our denominator will be 8.  We are looking to find how many 4s there are in the circle.  Since there is only ONE 4 in the circle, our nominator will be 1.  So, when we put that together, we get 1/8.

Answer:

1/8

Step-by-step explanation:

Given/To Find:

P(4)

Solve:

Since there are 8 number on the spinner. Which given us denominator will be 8.  And ONLY one of them is 4. Thus, Nominator will be 1.

Hence, that given us 1/8

ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.

Congruent triangles are triangles whose corresponding sides are congruent to each other.

The hypotenuse of triangle JKL(KL = 10) is congruent to a leg of triangle XYZ (YX = 10). This implies that they cannot be congruent triangles.

Therefore, ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.

Answer: The answer is C

Step-by-step explanation: Just took the test on edge

Based on the absolute deviations and the predicted values, the sum of absolute deviations will be 4.8.

This can be found as:

= ∑ (Observed value - Predicted value)

The observed values are given in the table and the predicted values will be calculated using y = 3.6x - 0.4.

Solving gives:

=  [3 - (3.6 x 1 - 0.4)] + [7 - (3.6 x 2 - 0.4)] + [ 9 - (3.6 x 3 - 0.4)] + [14 - (3.6 x 4 - 0.4)] + [15 - (3.6 x 5 - 0.4)] + [21 - (3.6 x 6 - 0.4)] + [25 - (3.6 x 7 - 0.4)]

= 0.2 + 0.2 + 1.4 + 0 + 2.6 + 0.2 + 0.2

= 4.8

Answer:

Volume: 75.39 ft^3

Surface area: 100.5 ft^2

Step-by-step explanation:

To find volume, you use the formula V=πr^2h (V=3.14*2^2*6)

To find the surface area you use formula A=2πrh+2πr^2 (A=2*3.14*2*6+2*3.14*2^2)

Answer:

w = 60

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

w + 20 is an exterior angle of the triangle , then

w + 20 = w - 10 + w - 30

w + 20 = 2w - 40 ( subtract w from both sides )

20 = w - 40 ( add 40 to both sides )

60 = w

Answer:

w=60°

Step-by-step explanation:

triangle=180°

angle on a straight line=180°

using that,

we need to find the angle on the same line with that of "w+20°" angle, so we name it as "X"

so, 180-(w+20)=X

expand bracket by multiplying it with the "-"

so it'll be: 180-w-20=X

then rearrange to get like terms together

180-20-w=x

160-w=x

so the missing angle in the triangle is now (160-w)°

now using the angles in a triangle =180°

we add all the angles and equate it to 180, so:

w-30+w-10+160-w=180°

collect like terms again:

w+w-w-30-10+160=180

2w-w+120=180

w+120=180

move 120 to the other side and remember the sign changes, so:

w=180-120

therefore w=60°

now you can substitute w=60 into the triangle and see you'll get 180°

Answer:

the median somewhere in the range of (120,160]

Step-by-step explanation:

the median is always the center of the data points.

There are 100 data points, so the median is the mean of the points 50&51.

Those points are found between 120 and 160 so the median is also found there.

As for an estimate, there isn't one.

Answer:

1/6

Step-by-step explanation:

This is conditional probability.

If heads is tossed, then and only then does he have the option to draw either green or red and have the full 'Head, Green/Red' combination.

So, the probability of the first event - getting heads, is 1/2, since either heads or tails can be flipped with 50/50 chance.

The probability of the second event - picking either green or red, is 1/3, since there are 6 colour options - blue, red, yellow, green, orange and purple - of which 2 can be chosen. Thus, 2/6, which simplifies to 1/3

Now since these are both independent events, we must multiply their probabilities.

1/3 * 1/2 = 1/6

The steps in the patterns A and B form a sequence

1/5 = 0.2

3/5 = 0.6

5/1 = 5

Hope this helps :)

Answer:

5/5

Step-by-step explanation:

if you want to divide 1 whole into a fraction then the top number would have to be the same as the bottom number, for example 5/5. The top number is 5 which is the same as the numerator which will equal to 1 whole.

While 1/5 and 3/5 is less than 1 whole

And 5/1 is more than 1 whole but its way past the numerator

Using it's concept, it is found that there is a 0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In an experimental probability, these number of outcomes is taken from previous trials.

Researching this problem on the internet, it is found that out of the 250 rolls, 10 resulted in a 5 on NC1 and 2 on NC2, hence:

p = 10/250 = 1/25 = 0.04.

0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.

Answer:

Total cost= 99 + 2.97x

Step-by-step explanation:

Giving the following information:

Fixed cost= $99

Variable cost= 3% per person

First, we need to calculate the 3% of 99:

Unitary variable cost= 99*0.03= $2.97

Now, we establish the total cost structure:

Total cost= 99 + 2.97x

x= number of people in attendance

Finally, suppose 200 people attend the party:

Total cost= 99 + 2.97*200

Total cost= $693

Answer:

99+3x

Step-by-step explanation:

Given;

Party cost $99

$3 per person who attends

To Find;

Which expression can Jess use to figure out the total amount of money she owes at the end of the party?

Solve;

Since, we don't know the total amount of money she owes at the end of the party.  Total amount of money she owes at the end of the party = x

Thus, Party Costs ($99) plus per person who attends($3)  and Total amount of money she owes at end of party (x)

As well as,

[A] 33x, [B] 33 + x, and [D] 99x+3 didn't clearly or completely shows  the party's situation. Hence, the Best Answer is [C] 99+3x
