Ralph’s shirt company sells t-shirts for $7.50 each with a flat rate of $10 for shipping. Frank’s t-shirt company sells t-shirts

IrinaVladis [17]

Answer:

I assume your asking who's is better and why?

Step-by-step explanation:

Ralph has stated that for 1 shirt it will cost

$7.50 + $10 shipping= $17.50

Frank says it's $10 a shirt no shipping

if you work out the cost of Ralph's up to 5 shirts using the equation

($7.50 x number of shirts ) + $10 shipping

with each equation replace number of shirts with the number 1,2,3,4 and 5

1 shirt will cost you $17.50

2 shirts will cost you $25.00

3 shirts will cost you $32.50

4 shirts will cost you $40.00

5 shirts will cost you $47.50

at Frank's shop

1 shirt will cost you $10

2 shirts will cost you $20

3 shirts will cost you $30

4 shirts will cost you $40

5 shirts will cost you $50

Frank's is better to buy no more than 4 shirts from as he's cheaper up to 4 shirts.

Ralph is cheaper for bigger orders with 5 or more shirts in them

The correlation between height and weight among men age 18-74 in the U.S. is about 0.40. Say whether each conclusion below follo

zzz [600]

Answer:

Options a, b, c are correct.

Step-by-step explanation:

First let's see the equation that governs the statement, which is the following:

$r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }$

Therefore, reading options a, b, c are correct.

Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.

This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.

that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.

Help, with all please.

UNO [17]

11) ∠Q+∠R+∠S=180°
let ∠Q=∠S=x
x+58+x=180
2x=122
x=61
since∠Q=∠S=x
∴∠Q=∠S=61°

12) M+N+P=180
x+2x-1+2x+1=180
5x=180
x=36
∴m=36

n=2x-1
=72-1
=71

p=2x+1
=72+1
=73

13) her answer is not reasonable because they are angles on a straight line and sum of angles on a straight line =180 and 86+86≠ 180.

Hope this was helpful.
