Triangle RST was reflected over the x-axis and translated 2 units to the left to form triangle ABC. The figures are congruent.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Reflection, translation and rotation are rigid transformation which preserve the shape and size of a figure, forming congruent figures.

Answer: a monomial has one term, binomial has 2 terms, and trinomial has 3.

Step-by-step explanation:

using a bit of greek and latin roots, we can observe that all 3 terms have the same suffix of nomial in them. From this, we know that mono means one, bino means two, and tri means 3. Fun fact, there's also polynomial (if you did or didn't know), which is multiple terms more than 3.

Answer:

20 km rate should 7.76

Step-by-step explanation:

Definitions

The variable rate is the rate for every km.

The fixed rate is what is charged for someone just getting on their bicycle.

Givens

Length of race = 6 km

variable rate = 0.22 / km

fixed rate = x

Total cost = 4.68

Formula

Total cost = fixed rate + variable rate * distance

Solution

4.68 = 6*0.22 + x

4.68 = 1.32 + x                       Subtract 1.32 from both sides.

4.68 - 1.32 = 1.32 - 1.32 + x   Combine

3,36 = x

The fixed rate is 3.36

Before getting the answer to the question asked, we should see if we get the same fixed rate for 24 km

Check

Total Cost = fixed rate + variable rate*distance

Total Cost = 8.64

fixed rate = x

variable rate = 0.22

distance = 24 km

8.64 = x + 0.22 * 24                Combine

8.64 = x + 5,28                        Subtract 5.28 from both sides

8.54 - 5,28 = x + 5.28 - 5,28  Combine

3.36 = x which agrees with our first calculation for the fixed rate.

Answer

y = 3.36 + 20*0.22

y = 3.36 + 4.4                           Combine

y = 7.76

The color that has the greatest difference between the theoretical and experimental probability is yellow.

Theoretical probability of each color = number of color in each section / total number of sections

1/5 = 0.2

Experimental probability is based on the result of an experiment that has been carried out multiples times

Experimental probability

Experimental probability of choosing orange = 118 / 625 = 0.19

Difference = 0.2 - 0.19 = 0.01

Experimental probability of choosing purple = 137 / 625 = 0.22

Difference 0.22 - 0.2 = 0.02

Experimental probability of choosing brown = 122 / 625 = 0.20

0.2 - 0.2 = 0

Experimental probability of choosing yellow = 106 / 625 = 0.17

0.20 - 0.1696 = 0.0304

Experimental probability of choosing green = 142 / 625 = 0.23

0.2272 - 0.20 = 0.0272

Answer:

8, 12, 16, 20, 24, 28, 32, 36

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

a₁ is the first term and d the common difference

given a₁ = 4 and a₁₀= 40 , then

4 + 9d = 40 ( subtract 4 from both sides )

9d = 36 ( divide both sides by 9 )

d = 4

add d to each term to obtain the next term

4 + 4 = 8

8 + 4 = 12

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

24 + 4 = 28

28 + 4 = 32

32 + 4 = 36

the 8 terms between 4 and 40 are

8, 12, 16, 20, 24, 28, 32, 36

The confidence interval or the mean noise level is (108.17,150.23) and sample standard deviation is 12.52.

Given noise levels:108,133,140,129,136. and confidence level 98%.

We have to find the confidence level and the sample standard deviation of the given data.

Confidence level=98%.

n=5

Sample standard deviation=[tex]\sqrt{(x-x bar)^{2} /n-1}[/tex]

=[tex]\sqrt{626.8/4}[/tex]

=[tex]\sqrt{156.7}[/tex]

=12.52

critical t value at 98% confidence level with degree of freedom(5-1) is 3.747

Standard error= critical t*s/[tex]\sqrt{n}[/tex]

Standard error is the difference between the real values and calculated values.

=3.747*12.52/[tex]\sqrt{5}[/tex]

=46.91/2.23

=21.03

Upper confidence interval=Mean +standard error

=129.2+21.03

=150.23

Lower confidence interval=Mean - standard error

=129.2-21.03

=108.17

Hence the confidence interval is (108.17,150.23) ,sample standard deviation is 12.52 and critical t value is 3.747.

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

3×10 on the bottom.

= (1×7)/(3×10)

7/30 cannot be simplified, so that is the answer.

Answer:

3.5kg

Step-by-step explanation:

Let original weight  of grapes in box be X and weight of grapes in basket be Y.

From the first sentence
X = 2Y  (weight in box = 2 times weight in basket)   --- (1)

If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2

From the second statement

Y + 2 = X + 0.5

Subtracting Y from the LHS gives 2 = X - Y + 0.5

Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5  --- (2)

Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg

But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg

The measure of angle of ∠BAM (θ) will be 9°. Then the correct option is D.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

ABCD is a rectangle with AB = 3BC.

And M is the mid-point of BC.

2BM = BC

Then the tangent of angle of ∠BAM (θ) will be

tan θ = (BM) / (AB)

tan θ = (BM) / (3BC)

tan θ = (BM) / (3 × 2BC)

tan θ = 1/6

     θ = tan⁻¹ (1/6)

     θ = 9.46°

     θ ≅ 9°

Then the correct option is D.

Binomial distribution will be used to know the probability that the total weight of the samples will exceed 530 pounds.

It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.

In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.

Option D is correct.

Figures are missing in the question.

The images below shows the missing figures of question.

For congruent figures, we need the same shape, same area, and inverse direction.

Congruent figures have congruency. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.

In the case of geometric figures, line segments with the same length are congruent and angle with the same measure are congruent.

In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects.

In this sense, two plane figures are congruent implies that their corresponding characteristics are "congruent" or "equal" including not just their corresponding sides and angles, but also their corresponding diagonals, perimeters, and areas.

The figure in option D satisfies all these conditions. Hence, Option D is correct.
