MaRussiya [10]

Complete question :

Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.

Answer:

1.625 yards

Step-by-step explanation:

Purple ribbon = 7/8 yards

Green ribbon = 1 1/6 yards = 7/6 yards

Total ribbon = 3 2/3 yards = 11/3 yards

Ribbon that is neither purple nor green :

Total ribbon - (green + purple ribbon)

7/8 - (7/6 + 7/8)

11/3 - (28 + 21) / 24

11/3 - 49/24

= 1.625 yards

Answer the following questions about the standard normal random variable Z. (Use 4 decimal places in your answers to parts a. th
Mashcka [7]

Answer:

a) 0.6636

b) 0.0951

c) 0,9474    

d)  0.0047

e) 0.9957  

f)   0.1308  

Step-by-step explanation:

We look in tables z values and then we see carefully aereas inside normal curve

a) P[- 1.46 < z < 0.63 ]     point 1.46 from table 0.0721  this s th area from value -1.46 to the left . And the value  z = 0.63  corresond to the area 0.7357 which includes the area between 1.46 to the left tail, then we have to subtarct and get 0.6636 .

P[- 1.46 < z < 0.63 ] = 0.6636             66.36 %

b) P [ 0 < z < 1.31 ] we just need the area for point 1.31   that is 0.0951

P [ 0 < z < 1.31 ] = 0.0951                   9.51 %

c)  P [z > - 1.62  ] = 1 - 0.0526

P [z > - 1.62  ] = 0,9474                       94.74 %

d) P[z < - 2.6 ] =   0.0047                       0.47 %

e) P [ z < 2.63 ] = 1 - 0.0043

P [ z < 2.63 ] = 0.9957                         99.57 %

f) P [ -2.58 < z < -1.1 ]  =  0.1357 - 0.0049 =  

P [ -2.58 < z < -1.1 ]  =  0.1308              13.08 %
