Answer:

Step-by-step explanation:

Let's examine each statement:

Option A: m<CUD = m<VUM (CORRECT)

Rationale: vertical angles are congruent to each other.

Option B: m<AUV + m<DUA = 180 (CORRECT)

Rationale: angles on a straight line

Option C: m<MUC - m<MUD = m<CUD (CORRECT)

Rationale:

m<MUC = m<MUD + m<CUD

Subtract m<MUD from each side

m<MUC - m<MUD = m<CUD

Option D is FALSE

Rationale:

m<PUD + m <VUP = 180° (angles on a straight line)

m<PUM + m<CUA ≠ 180°

Therefore,

m<PUD + m<VUP = m<PUM + m<CUA IS FALSE.

The IQ scores and English test scores of fifth grade students is given by the regression line 9 = -26.7 +0.9346s, where y is the

Phantasy [73]

Answer:

Option E) 2.68; The regression line under predicts the student's English test score.

Step-by-step explanation:

We are given the following information:

The IQ scores and English test scores of fifth grade students is given by the regression line

$y = -26.7 +0.9346s$

where y is the predicted English score and s is the IQ score.

Here English score is the predicted variable that is the dependent variable and the IQ score is the independent variable and plays the role of predictor.

An actual English test score for a student is 65.7 with an IQ of 96. We have to predict the English score with the help of regression equation.

Predicted or interpreted English score =

$y = -26.7 +0.9346(96)= 63.0216$

Thus, predicted English score is 63.0216.

Observed value of English score at IQ 96 is 65.7

Residual = Observed value - Predicted value

= $65.7 - 63.0216 = 2.6784 \approx 2.68$

Since the predicted value is less than the original or observed value we can say that the regression line under predict the English score.

Option E) 2.68; The regression line under predicts the student's English test score.

Can you help me with this question plzz?

Dominik [7]

Answer: The answer is 96 wizards.

Step-by-step explanation:

So what I like to do is fraction formatting.

you start with x/blank $\frac{blank}{120}$ and $\frac{80}{100}$ you do cross multiply divide

and multiple 120 by 80(=9600) and divide by 100 (=96) because wizards are 20% less of the population than goblins, so they are equivalent to 80% of the goblins! Hope this helped!

P ( x ) = | x | and the image I ( x ) = 1 2 ⋅ P ( x ) graph

Ivan

Answer:

The picture where the red image is the skinniest

Step-by-step explanation:

The graph P(x) denotes the graph of the parent graph for all the functions. And, It includes the vertex of (0,0) and points which are shown below:

x f(x)

-2 2

-1 1

0 0

1 1

2 2

Now as we can see in the attached figure i.e it changed the function points i.e given below for l(x) = 12P(x)

x f(x)

-2 24

-1 12

0 0

1 12

2 24

This depicts that it has a skinner graph that includes redish graph
