Triangle A″B″C″ is formed by a reflection over x = −1 and dilation by a scale factor of 4 from the origin. Which equation shows
juin [17]

Answer:

\frac{AB}{A''B''}  = \frac{1}{4}

Step-by-step explanation:

Given the information:

  • A'B'C' reflection over x = −1
  • dilation by a scale factor of 4 from the origin

<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so  A″B″C″ is 4 time bigger than ABC

=> the relationship between ΔABC and ΔA″B″C″

= \frac{AB}{A''B''}  = \frac{1}{4}

We choose C.

Hope it will find you well.

In a hypothesis test, what should we conclude if the data would be very unusual if the original assumption about our parameter w
Triss [41]

We conclude  the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.

  • A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
  • The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
  • If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.

One year, Mr James travels 8 x 10^3 miles for his job. The next year he traveled 1 x 10^4 miles. How many more miles did he trav
nignag [31]

Answer:

2 000 miles

Step-by-step explanation:

In the first year, Mr James travels 8 x 10^{3} miles = 8 000 miles.

The second year, he traveled 1 x 10^{4} miles = 10 000 miles.

Comparing the distance covered in the two years,

10 000 miles - 8 000 miles = 2 000 miles

Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.

Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.

I need help now please, I can’t figure this out
otez555 [7]

Answer:

B. 1,4

Step-by-step explanation:

1. substitute 4x for y in the second equation since we know y=4x(to find x)

6x-4(4x)=-10

2.solve for x

6x-4(4x)=-10

-4•4x=-16x

6x-16x=-10

6x-16x=-10x

-10x=-10

-10x/-10=-10/-10

x=1

3.substitute 1 for x in either equation(since x=1)to find y

y=4(1)

y=4

x,y=1,4

hope this helps!
