“I had a pretty normal day,” “I have little confidence in our ability to win today,” and “That’s so random!” are statements you

might use in conversation. We use a lot of everyday language to describe situations in statistics. Does the use of words that you’re already familiar with, such as normal, confidence, and random, help you understand the statistical concepts they describe? Explain why or why not.

I would say that yes, they do. The concepts are being described as normal, confident, and random. Those are describing the statistical concept the sentence is placed around.

Solve for the equation for the interval [0, 2pi). sec x/2 = cos x/2
Alenkinab [10]
Sec(x/2) = 1/cos(x/2)

sec(x/2)=cos(x/2) ----> cos^2(x/2)=1 ---> cos(x/2) = -1 and cos(x/2) = 1

Cos(x/2)=1 --- > x/2 = 0, only.  x = 0;

cos(x/2)=-1 ----> x/2 = pi -> x = 2pi. But the statement says [0,2pi), so 2pi can not be chosen.

Only x = 0.

In fact, your equation is equivalent to sec(x)=cos(x), for x in [ 0, pi), so yes, only x = 0 .

A rectangle was rotated 270° about the origin. The image is shown. Which points are vertices of the pre-image? Check all that ap
Temka [501]

Answer:

M(3, 2) and N(3, 1)

Step-by-step explanation:

A rectangle was rotated 270° about the origin.

Since it doesn't mention which direction, we will review both clockwise and anti-clockwise rotation.

See attached where top rectangle represents the pre-image before anti-clockwise and bottom one - before clockwise rotation.

<u>Now let's check the points given:</u>

K(–3, –1)

  • No

M(–3, 2)

  • No

M(3, 2)

  • Yes, top one

N(–3, 1)

  • No

N(3, 1)

  • Yes, top one

So based on correct points of pre-image we can state it was rotation anti-clockwise
