FGHI

Step-by-step explanation:

The square FGHI needs to be created into a reflection for true congruence of the figure thus transformed across the axis.

FGHI's co-ordinates' signs are to be reversed for reflection thus coordinates:

2,-5

4,-5

2,-7

4,-7

are made into

-2,5

-4,5

-2,7

-4,7

Answer:

<h2>Square FGHI is a reflection of square ABCD</h2>

Step-by-step explanation:

Notice that the square ABCD has coordinates A(2,2), B(2,4), C(4,4) and D(4,2).

The square FGHI is not directly a reflection of square ABCD, there is needed a translation three units upwards to get square FGHI as a reflection of ABCD.

Therefore, the answer is FGHI, because that's the square that needs an extra transformation to be a reflection of ABCD.

Answer:

Answer is 0.5

Step-by-step explanation:

The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.

The time slot and time of day remain same in both the text and the question.

The average or mean number of accidents is 1.1

QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?

In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?

Since the mean number of accidents is 1.1, 2 is above the mean.

Probability of 1.1 accidents is 1, since that's the mean (expected value).

Probability of 2 accidents is 1/2 which is = 0.5

A golfer keeps track of his score for playing nine holes of golf (half a normal golf round). His mean score is 8080 with a sta

solniwko [45]

Answer:

Therefore the mean and standard deviation of his total score if he plays a full 18 holes are 160 and $11\sqrt2$ respectively.

Step-by-step explanation:

Given that,

For the first 9 holes X:

E(X) = 80

SD(X)=13

For the second 9 holes Y:

E(Y) = 80

SD(Y)=13

For the sum W=X+Y, the following properties holds for means , variance and standard deviation :

E(W)=E(X)+E(Y)

and

V(W)=V(X)+V(Y)

⇒SD²(W)=SD²(X)+SD²(Y) [ Variance = (standard deviation)²]

$\Rightarrow SD(W)=\sqrt{SD^2(X)+SD^2(Y)}$

∴E(W)=E(X)+E(Y) = 80 +80=160

and

∴ $SD(W)=\sqrt{SD^2(X)+SD^2(Y)}$

$=\sqrt{11^2+11^2}$

$=\sqrt{2.11^2}$

$=11\sqrt2$

Therefore the mean and standard deviation of his total score if he plays a full 18 holes are 160 and $11\sqrt2$ respectively.

FA is a line, line segment, and a ray. tru or false

bezimeni [28]

Answer:

The answer is "false".

Step-by-step explanation:

The following are the description of the line, line segment, and ray.

Line: The line is a single-dimensional figure, which has a length but no width. It has the direct path of points, which runs to the next without stopping in both directions.
Line Segment: It is the portion of a line is called a segment. It has two end-points, which includes the endpoints for all the positions between these. The length of this section, can't be determined.
Ray: The ray would be a straight path for one destination and moves one way.
