The school store sells bottles of water and soft pretzels during lunch. Each bottle of water costs $0.75, and each pretzel costs $1.25. During one lunch period, the number of water bottles sold and the number of pretzels sold added up to 97, and the store made $96.25. Which system of equations could you write to answer this question: How many bottles of water, w, and how many pretzels, p, did the school store sell?

a.) w + p = 97
1.25w + 0.75p = 96.25

b.) w + p = 96.25
1.25w + 0.75p = 97

c.) w + p = 97
1.25w + 0.75p = 96.25

d.) w + p = 97
0.75w + 1.25p = 96.25

Answer:

4860 or either 108

Step-by-step explanation:

Answer:

360 in²

Explanation:

The given figure is a wedge.

If you need the surface area then,

Height×Base=(9×12)=108 in²

2nd Base×Length=(3×15)=45 in²

Height×2nd base=(9×3)=27 in²

Base×Length=(12×15)=180 in²

Then add all of them=(108+45+27+180)in²

                                  =360 in²

∴The area of the wedge is 360 in²

Answer:

The variable is w and the independent is all of the other factors.

5+3x4=four weeks of shells

5+3x10=ten weeks of shells

Answer:

10 is 14 (10,14) and 5 is 16 (5,16)

Step-by-step explanation:

the output is the same as the x value or the number of rides taken. The y is the amount on the card, or how much money is left of the card. So to solve this question, you want to follow the x-axis (the bottom numbers) til you reach the output you need then match that with the input by looking directly left on the chart. Hopes this helps!

Answer:

Step-by-step explanation:

10r - r-6r+11 - Constant = 11 & coefficient = r

19-5n-8+14 - constant = 8,14,19 & coeff = n

-5-13y-2y-18 - constant = -5,18 & coeff = y

8a-7b+1-2b+3a - constant = 1 & coeff = a,b

11x-4y+2x+8 - constant = 8 & coeff = x,y

Answer:

20 - 1.75n

Step-by-step explanation:

20 = total amount of money

1.75 = cost of each card

n = number of cards she buys

Answer:

A) the median of brand a is higher than brand b

Step-by-step explanation:

Typically means usaully and that means the weights that the bars usaully are so if you compare the meadian weights that the two brands typically are, brand A would usually be heaver.

I'm bad at explaining things but I hope this helps.

Answer:

the answer is B (x and y have a weak, positive correlation)

Give the person above me brainlyest for helping!

Step-by-step explanation:

The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.

Here, given values of x and y

x   1    2    3   4   5    6

y   3   4    9   7    2    18

xy  3   8   27  28 10  108

x²   1   4    9    16   25   36

y²   9  16  81  49  4  324

∑x = 21,  ∑y = 43,  ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6

Now, Correlation between x and y

r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]

r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]

r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)

r = 261 / √ 105 X 1049

r = 261 / √110145

r = 261 / 331.88

r = 0.78

Thus, The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

Answer:

First answer is correct

Step-by-step explanation:

Answer:

OK.

Now

The points that Make this triangle are

A(-2, 3)

B(-3, 1)

C(-1, 1)

When we Translate 6units right and 2 units Up...

It means

Say we have point (x,y)

we translate 6 units right(Referring to the x coordinate) and 2 units up(referring to y coordinate)

So after translation

Point (x,y) would be (x+6 , y +2)

So Lets apply this to the points given above

A(-2,3) Would be (-2+6 , 3+2) = (4,5)

B(-3,1) would be ( -3+6 , 1+2) = (3,3)

C(-1,1) would be (-1+6 , 1+2 ) = (5, 3)

So We have It

Our Answer

is
