I hope this helps you



-2/2t+4w=6


-4t-8w= -12


4t+6w=15


-2w=3


w= -3/2


2t-4.3/2=6


2t=12


t=6

Julie's MP3 player contains 860 songs. If 20% of the songs are rap songs and 15% of the songs are R&B songs, how many of the
docker41 [41]
Total number of songs in Julie's MP3 player = 860
Percentage of rap songs in Julie's MP3 player = 20%
Then
Number of rap songs in Julie's MP3 player = (20/100) * 860
                                                                     = 860/5
                                                                     = 172
Percentage of R&B songs in Julie's MP3 player = 15%
Then
Number of R&B songs in Julie's MP3 player = (15/100) * 860
                                                                        = 1290/10
                                                                         = 129
So
The number of other types of songs in Julie's MP3 player = 860 - (172 + 129)
                                                                                             = 860 - 301
                                                                                             = 559
So the number of other types of songs in Julie's MP3 player was 559.

The best option is C. 0.0823mean = np = 48*1/4 = 12 

SD = sqrt(npq) = sqrt(48 *1/4 *3/4) = 3

"exactly 15" means 14.5 to 15.5 

z1= (14.5-12)/3 = 0.833 , z2 = (15.5-12)/3 = 1.167 

P(0.833 < z < 1.167) = 0.0808

How do you solve 45 = 3 (x + 1) using the distributive property?
Damm [24]

Answer:

x=14

Step-by-step explanation:

45 = 3 (x + 1)

Distribute the 3 to both terms in the parentheses

45 = 3x +3

Subtract 3 from each side

45-3 = 3x+3-3

42 = 3x

Divide each side by 3

42/3 = 3x/3

14 =x
