What does the coefficient of determination is 0.49 mean ? a. The coefficient of correlation of 0.70, b. There is almost no correlation because 0.70 is close to 1.0. c. Seventy percent of the variation in one variable IS explained by the other variable d, Tne coefficient of nondetermination is 0.30.

Answers

Answer 1

The coefficient of determination of 0.49 means that approximately 49% of the variability in the dependent variable can be explained by the independent variable(s) in the regression model. In other words, the model is able to explain 49% of the total variation in the response variable.

The coefficient of correlation of 0.70 indicates a strong positive linear relationship between the two variables. It means that there is a high degree of association between the independent and dependent variables, and that the change in one variable is closely related to the change in the other variable. A correlation coefficient of 0.70 is considered a moderate to strong correlation, with values closer to 1 indicating a stronger relationship.

A stone falls from a train trestle. The stone's height in meters above the ground is modeled by the function h(t)=−4.9t2+155 where t is time in seconds. To the nearest tenth of a second, how long does it take the stone to hit the ground? State what strategy you will use to answer the question, and then find the answer.

Answers

Answer:

5.6s

Step-by-step explanation:

Given the height reached by the stone modeled by the equation

h(t)=−4.9t2+155 where t is time in seconds.

The stone hits the ground at h(t) = 0

Substitute

0 = -4.9t²+155

4.9t² = 155

t² = 155/4.9

t² = 31.63

t = ±√31.63

t = 5.62seconds

Hence it will take 5.6s to reach the ground(to the nearest tenth)

If triangle DEF and triangle MNO are two triangles such that DE = MN and EF = No, which of the following would be sufficient to prove the triangles are congruent?

A DE/MN = EF/NO
B DE=DF
C angle D = angle m
D angle E = angle N

Answers

Answer:

The answer is D

angle E=angle N

As N and E are the corresponding angles between those equal sides D. angle E = angle N is sufficient to prove that the triangles are congruent.

What is congruency?

Congruency is geometry that states similarities between two or more figures generally with their respective sides and angles.

We know we can prove that two triangles are congruent by sides and angles.

Given that DEF and MNO are two triangles and side DE = MN and side EF = NO, in which angles N and E lie between those two sides and therefore we can apply SAS( side angle side) congruency to prove that they are congruent.

Steve manages a skate park and he has been analyzing the attendance data. Steve finds that the number of visitors increases exponentially as the temperature increases, and this situation is represented by the function f(x) = 5x. Steve also finds a linear equation that models the number of people who leave the park early depending on the change in temperature, and it is represented by f(x) = −x + 6. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.

Answers

Answer:Suppose that the equations are:

The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.

N(T) = a0*r^(T)

Also, the number of people that leaves the park as the temperature increases are:

M(T) = a*T + b

So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:

N(T) - M(T) = total change in the park population as the temperature changes = C(T)

C(T) = a0*r^(T) - a*T - b

She needs altogether 2 2/4. that is 2 wholes and 2/4 fraction. if we consider using 1/4 cup, 1 whole is made of four quarter cups. Therefore 2 wholes require eight quarter cups. Then theres a remaining fraction of 2/4 which is equivalent to two quarter cups. 1/4 + 1/4 = 2/4. Therefore altogether 8 + 2 = 10 of the 1/4 cups are required for the recipe. 10 of 1/4 cups are needed is this right? Yes or no

Answers

Answer:

Yes

Step-by-step explanation:

According to the analysis;

There are four 1/4 cups in one whole

There are eight 1/4 cups in two wholes

Then the fraction 2/4 = 1/4 + 1/4 Hence there are two 1/4 cups in 2/4.

Altogether we have the fraction 2 2/4 as 8 + 2 = 10 measures of 1/4 cups

To confirm, 10 * 1/4 = 2 2/4

Therefore, the analysis is correct.

Four square tiles, each of side 12 cm are used to make a bigger tile. Find the perimeter of the larger tile.

Answers

Answer:

192 cm

Step-by-step explanation:

Given that:

Side length of small tiles = 12cm

Number of small tilea used to make a bigger tile = 4

The perimeter of larger tile:

Perimeter of a square = 4s

Where, s = side length

Side length of larger tile :

4 * side length of smaller tile

4 * 12

= 48 cm

Hence,

Perimeter of a larger square tile = 4s

4 * 48cm

= 192 cm

Adam has x baseball cards Ben has twice as many as Adam Carlos has 8 more than Adam Write the expression that indicates how many cards that Carlos has.

Answer:

Step-by-step explanation:

Hello,

I am pretty sure all this would be is :

Let c = Carlos's baseball cards

c = x + 8

Since Ben in this problem is irrelevant to Carlos, we just are using Adams cards and adding 8 onto them to find Carlos's cards since he has 8 more.

Since :

"Carlos has 8 more than Adam Write"

"Adam has x baseball cards"

So:

c = x + 8

The answer is 48 square inches as the perimeter.

The perimeter of the rectangle is 48 inches.

What is rectangular perimeter?

The whole distance that a rectangle's borders, or its sides, cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the total of its four sides.

Given:

The rectangle has an area of 128 square inches and a width of 8 inches.

That means, the length,

= area of the rectangle / the width of the rectangle

= 128/8

= 16 inches.

The perimeter of the rectangle,

= 2 (length + width)

= 2 (16 + 8)

= 48 inches.

Therefore, the perimeter is 48 inches.
