Eliza likes to make daily events into games of chance. For instance, before she went to buy ice cream at the local ice cream par

sergejj [24]

Answer:

1/6

Step-by-step explanation:

two events need to happen: tutti frutti needs to be shown by first spinner and second spinner needs to show dish

probability of tutti frutti = 1/3

probability of dish = 1/2

probability of both events = 1/3 * 1 /2 = 1/6

The value of the coefficient of correlation ( r) a. can never be equal to the value of the coefficient of determination (r2). b.

gulaghasi [49]

Answer:

d. can be equal to the value of the coefficient of determination (r2).

True on the special case when r =1 we have that $r^2 = 1$

Step-by-step explanation:

We need to remember that the correlation coefficient is a measure to analyze the goodness of fit for a model and is given by:

$r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}$

The determination coefficient is given by $R= r^2$

Let's analyze one by one the possible options:

a. can never be equal to the value of the coefficient of determination (r2).

False if r = 1 then $r^2 = 1$

b. is always larger than the value of the coefficient of determination (r2).

False not always if r= 1 we have that $r^2 =1$ and we don't satisfy the condition

c. is always smaller than the value of the coefficient of determination (r2).

False again if r =1 then we have $r^2 = 1$ and we don't satisfy the condition

d. can be equal to the value of the coefficient of determination (r2).

True on the special case when r =1 we have that $r^2 = 1$

Theo started to solve the quadratic equation (x + 2)2 – 9 = –5. He added 9 to both sides and the resulting equation was (x + 2)2

BigorU [14]

we have

$(x + 2)^{2}-9=-5$

Adds $9$ both sides

$(x + 2)^{2}-9+9=-5+9$

$(x + 2)^{2}=4$

square root both sides

$(x+2)=(+/-)\sqrt{4}\\(x+2)=(+/-)2\\x1=2-2=0 \\x2=-2-2=-4$

therefore

<u>the answer is</u>

the resulting equation is $(x+2)=(+/-)2$

PLZ HELP I'M BEING TIMED Henry is purchasing a number of magnets. He wants some idea of how many he can buy. On a coordinate pla

Igoryamba

Answer:

Options B, E, F

Step-by-step explanation:

Every 3 magnets that you buy, you need to pay 1 more dollar. Therefore, if you have 9 magnets, the cost will be 3 dollars. Also, if you have 6 magnets, the cost will be 2 dollars. Finally, if you have 3 magnets, the cost will be 1 dollar. So... the correct options are Options B, E, F
