Answer:

2.38 lb bag = 4.99/lb 5.08 lb bag = 5.21/lb The 2.38 is the better buy

Step-by-step explanation:

1.88/2.38 = 4.99

26.47/5.08 = 5.21

4.99 is cheaper than 5.21 so the 2.38 lb bag is better buy

Describe what solving a trigonometric equation is.

AleksAgata [21]

That's an awfully broad question. Could you not be more specific?

A basic example: Suppose you are told that sin theta = 1/2. Solving this equation would require finding the measure of the angle theta. In this case the answer would be "30 degrees," or "pi/6 radians."

300 ml over 15 min is what rate of ml per hour

Mama L [17]

Answer:

1200 ml per hour

Step-by-step explanation:

To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:

$\frac{300~ml}{15~min}=\frac{x~ml}{60~mins}$

Now we solve for x:

$\frac{300~ml}{15~min}\cdot 60~mins=x~ml$

$\frac{18000~ml}{15} =x~ml$

$1200~ml =x~ml$

And so, now that we know the value of x, the rate we wanted to find is

$\frac{1200~ml}{60~mins}$

Which is just 1200 ml per hour.

gtnhenbr [62]

Answer:

a. 0.333

b. 0.657

c. 1.667

d. -4.07

Step-by-step explanation:

a. Expected time of the first purchase is 10/30 = 0.333

b. Probability for time of 0.14 minutes before first purchase is :

e^-rt, r = 30/10 = 3 , t = 0.14

e^ -3 * 0.14 = 0.65704

c. Expected time until 5th order :

1 / [30/10] * 5 = 1.6667

d. Probability that 8th purchase will occur between 1.33 and 2 minutes ;

[30/10 ] / [ 1/2] = 6

Chi squared distribution ;

1.33 * 6 - 2 * 6 = -4.02

The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1 ⇒ 3rd answer

Step-by-step explanation:

In A graph:

Points are shown on ordered pairs (0 , 0) , (1 , 7) , (2 , 14) , (3 , 21) and (4 , 28) are connected by a line
The label on the x-axis is Lemon-Lime Soda in cups
The label on the y-axis is Strawberry Juice in cups

We need to find the ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda

∵ The points are connected by line

∵ The x-axis represents the number of cups of Lemon-Lime Soda

∵ The y-axis represents the number of cups of Strawberry Juice

∴ The ratio of the the number of cups of strawberry juice to the

number of cups of lemon-lime soda equal to the slope of the line

∵ The slope of the line $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

- You can calculate the slope of a line from any two points lie on it

∵ Points (1 , 7) and (2 , 14) lie on the line

∵ $x_{1}$ = 1 and $x_{2}$ = 2

∵ $y_{1}$ = 7 and $y_{2}$ = 14

∴ $m=\frac{14-7}{2-1}=\frac{7}{1}$

∵ The ratio of the number of cups of strawberry juice to the number

of cups of lemon-lime soda = m

∴ The ratio of the number of cups of strawberry juice to the number

of cups of lemon-lime soda = 7 : 1

The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1
