liq [111]
The difference between the first quarter and the third quarter is $2,411.44 because if you subtract the third quarter profits ($7,429.84 cents) from the first quarter profits (9,841.28 cents), you would get the difference which is $2,411.44 cents. 

Hope this helps :)

Solve. <br> 5-(x-6)=-7+3(-x+2)
Goryan [66]

Answer:

x=-6

Step-by-step explanation:

For this equation, when we remove the parenthesis, we get 5-x+6=-7+-3x+6.

Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.

Answer:

Emilia bought 28 sweets

Step-by-step explanation:

now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.

65-15+10=60 and now just do that simply ratio

E:Z=7:8

E+Z=7x+8x

60=15x

4=x

7x=28=Emilia

8x=32=Zakiah

Accuracy test:

(28+15)+(32-10)=65

28 is 4•7 and 32 is 4•8

storchak [24]

Answer:

Step-by-step explanation:

Given that researchers wondered whether the size of a​ person's brain was related to the​ individual's mental capacity

They selected a sample of 5 females and 5 males and measured their MRI counts and IQ scores.

The data is reported to the right. Complete parts ​(a) through ​(d) below.

We want scatter plot for IQ vs MRI in general.

So we group data into two columns X for MRI and Y for IQ and draw scatter plot

MRI IQ

 

816932 133

1001121 140

833868 132

856472 140

866662 130

1038436 139

1079550 141

924059 136

a) Scatter plot is attached as a file

b) correlation coefficient = Cov (x,y)/S_x S_y = 0.729889

B) Yes, MRI count and IQ are linearly related since the linear correlation coefficient is _____.0.729889 >0.5 and near to 1 than to 0

There is a positive moderate correlation between x and y (linear)
