Convert 6\frac{3}{8}683 to improper fraction. Use this rule: a \frac{b}{c}=\frac{ac+b}{c}acb=cac+b:
∣86×8+3−2∣+∣−885−1∣

Simplify 6\times 86×8 to 48: 
848+3−2∣+∣−885−1∣

Simplify 48+348+3 to 51:
851−2∣+∣−885−1∣

 Make the denominators the same:
51/8−2×88

Simplify. Denominators are now the same:

51/8−816

Join the denominators: \frac{51-16}{8}851−16

etc.. and your answer will be 14

Hello from MrBillDoesMath!

Answer:

Number marbles >= 5

Discussion:

The only certain thing we can say is the jar contains at least 5 (green) marbles. The table shows probabilities, not certainties, and is no guarantee that any other marbles even exist in the jar,

Thank you,

Give an example for a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles

cluponka [151]

Answer:

One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles.

Step-by-step explanation:

so if I was you I would use that strategy to try to find the pair of the Alternate exterior angles.

so the agles are probably 1 and 7 but i don’t want you to get it wrong so here’s a picture Of an example.

A package contains 12 resistors, 3 of which are defective. If 4 are selected, find the probability of getting

s344n2d4d5 [400]

Answer:

Incomplete question, but I gave a primer on the hypergeometric distribution, which is used to solve this question, so just the formula has to be applied to find the desired probabilities.

Step-by-step explanation:

The resistors are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$
