2) two florist purchased flower bouquets and vases at the same store. The first florist bought 2 flower bouquets and two vases f

Feliz [49]

Let
b---------> the cost of one flower bouquet
v--------> the cost of one vase.

we know that
2b+2v=12.50-----> Multiplied by -1------------->-2b-2v=-12.50
8b+2v=29---------------------------------------------> 8b+2v=29
I add the two equations ------------------------
6b=16.50
b=2.75
2*2.75+2*v=12.50---------------> v=(12.50-5.5)/2---------> v=3.5

the answer is
the cost of one flower bouquet is $2.75
the cost of one vase is $3.5

An ordinary Fair die is a cube with the number 1 through 6 on the sides (represented by painted spots). imagine that such a die

aleksandrvk [35]

Event A Answer: $\frac{5}{12}$

Step-by-step explanation:

sum greater than 7 leaves are the following combinations for 8, 9, 10, 11, and 12:

8 = 26, 35, 44, 51, 62 (5 possibilities)

9 = 36, 45, 54, 63 (4 possibilities)

10 = 46, 55, 64 (3 possibilities)

11 = 56, 65 (2 possibilities)

12 = 66 (1 possibility)

This is a total of 15 possibilities out of 36 total: $\frac{15}{36}$ = $\frac{5}{12}$

***********************************************************************************

Event B Answer: $\frac{1}{2}$

Step-by-step explanation:

sum is an even number means both dice are odd or both dice are even. That results in the following combinations:

11 13 15

22 24 26

31 33 35

42 44 46

51 53 55

62 64 66

This is a total of 18 possibilities out of 36 total: $\frac{18}{36}$ = $\frac{1}{2}$

A researcher wants to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used

pantera1 [17]

Here we are given the specific equation of:

amount of eroded soil = 0.4 + 1.3 x

where x is the flow rate

A linear equation has a general formula in the form of:

y = m x + b

where m is the slope and b is the y intercept of the equation

If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:

m = 0.4

b = 1.3

Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.

Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.

Answer:

positive, but we cannot say what the exact value is
