A study took a random sample often married couples, and asked the husband's and wife's age. The scatterplot shows the association between the ages of the husbands and wives. Not surprisingly, older husbands tend to have older wives, so the data has a positive linear association. A researcher finds that the least squares regression equation for this relationship is ŷ= 0.89 x + 2.62.
Suppose you interview a married man who has lived to the ripe old age of 100, and still married to his wife. using the least squares regression equation, predict his wife's age.

A. 100
B. 89
C. 91.62
D. 86.38​

—my answer is option (c.) 91.62
Any reviews would be much appreciated...

Answer:

Maggie is 5 years old

Step-by-step explanation:

3M-4+M=16

add 4 to both sides

4M=20

Divide both sides by 4

20/4 = 5

M/Maggie is 5

Answer:

Step-by-step explanation:

You want to get x on one side and the constants on the other. First subtract both sides by 3x to get:

-29 = 3x - 7

Now add 7 to both sides to get:

-22 = 3x

Divide each side by 3 to get:

x = -22/3

Step-by-step explanation:

              Given                   Parallel lines                 Converse

a). ∠13 ≅ ∠17                           a║c                  Corresponding angles

b). ∠4 ≅ ∠9                             b║e                  Exterior alternate angles

c). m∠19 + m∠22 = 180°         a║b                  Same side exterior angles

d). ∠8 ≅ ∠19                                                     Vertical angles.

e). ∠10 ≅ ∠23                         b║c                   Alternate angles

f). m∠14 + m∠17 = 180°           a║c                   Same side Interior angles

Answer:

0.8

Step-by-step explanation:

From the given information:

The population mean = 60

The standard deviation = 8

The sample size = 100

The sample distribution which follows a normal distribution is the set of values ​​taken by this statistic on each sample from the same population.

The standard deviation of the comparison distribution's = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]

The standard deviation of the comparison distribution's = [tex]\dfrac{8}{\sqrt{100}}[/tex]

The standard deviation of the comparison distribution's = 8/10

The standard deviation of the comparison distribution's = 0.8

                   -

7,680,000

__________

2,320,000

Answer:

2,320,000

Step-by-step explanation:

You have to subtract the 10,000,000 by the amount that has already been sold in order to find out the difference on how many copies are left in order to receive an award.  

10,000,000 - 7,680,000 = 2,320,000

Answer:

  (a) 6 °C

  (b) -3.7 °C

  (c) the y-intercept is (0, 10); the x-intercept is (10, 0)

Step-by-step explanation:

(a) The graph tells you the wind chill is 6 °C when the wind speed is 4 m/s.

__

(b) The annotated point on the graph tells you the wind chill is -3.7 °C when the wind speed is 20 m/s.

__

(c) The intercepts are marked on the graph. The y-intercept is (0, 10); the x-intercept is (10, 0). These represent the temperature when the wind speed is 0, and the wind speed when the temperature is 0, respectively.

Answer:

116°

Step-by-step explanation:

Answer:

4x6=24

Since 24 is 4 times as many as six, it means 4x6 is 24.

Answer:

The range of a function is the set of outputs the function can give

The y-axis on the graph shows as the output of the function

From the graph, we can see that the outputs of this specific function range from 0 to 5

Therefore, the range of this function is:   [0 , 5]

Answer:

-3

Step-by-step explanation:

so you you divide 2 into 6 and you know that 6 is already negative so you just put the negative sign by the three hope this answer ya question.

Step-by-step explanation:

A

is 45

B

C

is 90

hence

A+B+C=180

=45+45+90 =180

Step-by-step explanation:

The Desmos graphing utility is available as an app for phone or tablet from the app stores for Android and Apple devices. It is available from the desmos web site by clicking on "Graphing Calculator" on the home page.

Attached is a screen-shot of the web version. Help can be found under the (?) button at upper right. I found the help to be useful when first starting or when trying to do something I haven't done before.

You can create an account, if you like, but that is not necessary to obtain all of the basic functionality.

A link for sharing a graph will be generated by clicking on the icon to its left. Graphs can also be saved for later reference, if you have an account. The link to a graph will work whether you have an account or not.

__

There are other desmos tools available, too, for general calculation, geometrical construction, and matrix manipulation. (I have not yet used those.)

_____

Desmos likes to use x and y for the independent and dependent variables, respectively. You can define something like h(t) = 5t+1 and it will graph it as though it were y=5x+1. When you click on an equation or graph, points of intersection with other graphs or with the axes will be highlighted. Clicking on those highlights will give their coordinates.

Equations don't need to be of the "y=" form. For example, you can use x^2+y^2=1 to make a unit circle. The usual math symbols work for keyboard input (* for multiplication; / for division; ^ for exponents). The tab or arrow keys move out of denominator or exponent fields. To make more complicated exponents, parentheses help.

There's so much more it can do. It is worthwhile to visit the on-line tutorial information.

Answer:

Step-by-step explanation:

Pat believes that [tex]\sqrt{2}+\sqrt{8}=(2)(2)^{\frac{1}{2}}[/tex]

[tex]\sqrt{2}+\sqrt{8}=\sqrt{2}+\sqrt{4\times 2}[/tex]

             [tex]=\sqrt{2}+2\sqrt{2}[/tex]

             [tex]=3\sqrt{2}[/tex]

             [tex]=3(2)^{\frac{1}{2} }[/tex]

But [tex]2(2)^{\frac{1}{2}}\neq 3(2)^{\frac{1}{2}}[/tex]

Therefore, Pat's belief is not correct.

Camilla believes that [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex]

Which is correct as we have calculated above.

Therefore, [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex] will be the correct answer.
