Assume you have a bag containing 3 blue marbles & 2 red marbles

Suppose the event is to pick one red marble.

The probability of choosing one red marble =2/5 = 0.4

If you replace it in the bag & I ask you the probability of getting a red marble you will see that P(red marble) is always 2/5 = 0.4

Now if for the 2nd draw you dont replace it & I ask again the P(red), you will notice there is one red marble less & the P(red) on the second draw will be
P(red (2nd draw) = 1/4 (since the remaining in the bag are 1 Red & 3 Blues.

geniusboy [140]

Answer:

b. y=sec(x/3) and y=-1

Step-by-step explanation:

sec(x/3) + 4 > 2 − sec(x/3)

2 sec(x/3) > -2

sec(x/3) > -1

Graph y = sec(x/3) and y = -1.

What's p-(8+m) over -1+p if m is 1 1/9 and p is 1 7/8 please help
djyliett [7]
(p-8-m)/(-1+p)=1 1/9;p=1 7/8
(p+1)/(p+8+m)=1 1/9;p=1 7/8
1/(8+m)=10/9;p=15/8
that's as far as it can be solved

Porsha calculates the amount of money she will have at the end of 6 years on a $5,000 investment earning 3.75% interest compound
OLEGan [10]
Porsha` s expression:
5,000 ( 1 + 0.0375 ) ^24
A = P * ( 1 + i  ) ^n
n = 6 * 4 = 24
i = 0.0375 : 4 = 0.009375
Porsha`s expression is wrong. True expression is:
5,000 * ( 1 + 0.009375 ) ^24
Answer: B ) Porsha`s expression should have 1 + 0.009375 in the parentheses.

I need these from least to greatest A.11^4/11^11 B.1/11^-4 C.(11^-3)^-3 D.11^5•11^2
Sliva [168]

Answer:

\frac{ {11}^{4} }{ {11}^{11} } < \frac{1}{ {11}^{ - 4} }   < {11}^{5} . {11}^{2}  <  ( {11}^{ - 3} )^{ - 3}

Step-by-step explanation:

A) \frac{ {11}^{4} }{ {11}^{11} }  =  {11}^{4 - 11}  =  {11}^{ - 7}  \\  \\  B)\frac{1}{ {11}^{ - 4} }  =  {11}^{4}  \\  \\C) ( {11}^{ - 3} )^{ - 3} =  {11}^{ - 3( - 3)}  =  {11}^{9}   \\  \\  D){11}^{5} . {11}^{2}   =  {11}^{5 + 2}  =  {11}^{7}  \\  \\  \because \:  {11}^{ - 7}  <  {11}^{4}  <  {11}^{7}  <  {11}^{9}  \\  \\  \therefore \: \frac{ {11}^{4} }{ {11}^{11} } < \frac{1}{ {11}^{ - 4} }   < {11}^{5} . {11}^{2}  <  ( {11}^{ - 3} )^{ - 3}
