Answer:

Option A

Step-by-step explanation:

Bag A: 30 cents per bag

Bag B: 31 cents per bag

In order to find Cents per bag divide the number of bags from the amount it costs.

Bag A: 6 ÷ 20 = 0.30

Bag B: 9.92 ÷ 32 = 0.31

Answer:

B

Step-by-step explanation:

I say B cost the least per bag. I divided 32 by 9.92 and 20 by 6. That gives me the answers to what each bag costs. bag A costs 3.34 for each bag and bag B costs 3.22. So bag B is cheaper.

Match each expression to the correct point
ziro4ka [17]

Using number line and mental mathematics, the value of u = -√25, t = - 2π, s = -√68

<h3>What is a number line?</h3>

A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present.

The usage of the number is determined by the question that it corresponds to, such as when graphing a point.

As we can observe that

All the points lie on negative axis. The value of u = -√25 = 5

t = -2π = -2×3.14 = -6.28

s = -√68 = - 8.24

Six of the nine students are from middle gerogia state college. What is the probability that all three interviewed students are
ozzi

Answer:

0.2381 = 23.81%

Step-by-step explanation:

To calculate this probability, we can calculate the probability of each student of the 3 students interviewed being from middle georgia state college.

If inicially there are six students from middle georgia state college among the nine students, the probability of the first student chosen being from middle georgia state college is 6/9.

Then, as one student was already picked, we have now 5 students from middle georgia state college in a total of 8 students, so the probability of the second student will be 5/8.

In the same way, the third student will be picked in a group of 7 students, where 4 are from middle georgia state college, so the probability is 4/7.

Multiplying all the probabilities, we have the probability of all three students interviewed being from middle georgia state college:

P = (6/9) * (5/8) * (4/7) = 120/504 = 0.2381 = 23.81%

Indefinate integral of sin-1(x? i know you have to use integral by parts: u = sin-1(x v = x
svet-max [94.6K]
Yes 
you let u = sin-1 x and dv = 1 ( so v = x)
and use the rule
 INT udv    =  uv - INT vdu
                  = x sin^-1 x  - INT x sin-1 x

u = sin-1 x  so x = sin u 
dx/du = cos u  , du/dx = 1 / cos u  = 1 /  sqrt(1 - sin^2)  = 1 / sqrt (1-x)^2
so substituting we have 

INT sin-1(x)  = x sin-1x  - INT ( x / sqrt(1- x^2)
                      = x sun-1 x - ( - sqrt (1 - x^2)
                      =  x sin-1 x + sqrt(1 - x^2) + C
