Answer:

True

Step-by-step explanation:

A normal distribution shows a dense center , which would be the mean. Given a population or sample, the bulk of the data would be found near the mean and and spreads out thinner towards the ends when the data is said to be normally distributed. When graphed you will see that the data form a bell-shaped curve.

Attached below is an example of how it would look:

The triangle STU shown on the coordinate grid below is reflected once to map onto triangle S'T'U': Triangle STU drawn on a 4 qua
Andreyy89
Given that triangle <span>STU is reflected once to map onto triangle S'T'U'.
Given that triangle STU has vertices S(8, 6), T(2, 2), U(5, 1).

If vertex T' is at (2, −2), this means that triangle STU is refrected across the x-axis.

A refrection across the x-axis results in an image that has the same x-value as the pre-image but a y-value that has the opposite sign of the y-value of the pre image.

Thus, a point, say (x, y), refrected over the x-axis will result in an image with coordinate (x, -y)

Therefore, given that the coordinate of S is (8, 6), then the coordinates of vertex S'</span>  is (8, -6).

Answer:

The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is \mathbf{Speed=\frac{100}{20} }

Step-by-step explanation:

We are given:

Distance = 100 m

Time = 20 s

We need to find:

Speed

The formula used is: Speed=\frac{Distance}{Time}

Putting values and finding the expression

Speed=\frac{Distance}{Time}\\Speed=\frac{100}{20}

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is \mathbf{Speed=\frac{100}{20} }

<em>Note: Kindly recheck your options, As option B is not written correctly.</em>
