Step-by-step explanation:

z-score of X = 6150

\frac{6150 - 6250}{250}   =  - 0.4 \\

z-score of X = 6350

\frac{6350 - 6250}{250}  =  - 0.4

P(X<6150) + P(X>6350)

=P(z<-0.4) + P(z>-0.4)

=0.3446+0.3446

=0.6892

Solution:

<u>Note that:</u>

  • Given inequality: 3 < x + 3 < 6

<u>Solving the inequality one by one.</u>

  • 3 < x + 3
  • => -3 + 3 < x
  • => 0 < x
  • => x + 3 < 6
  • => x < 6 - 3
  • => x < 3

The inequality is <u>0 < x < 3.</u>

1+4=5 2+5=12 3+6=21 8+11=?
g100num [7]
I think the pattern is that you multiply the first number by the second , then add the first number. SO:
e.g. for the first one 1 x 4 = 4 , 4 + 1 = 5
for the second one 2 x 5 = 10, 10 + 2 = 12...
So for 8+11:
you do 8 x 11 = 88 , 88 + 8 = 96

Ricky jogged 6 miles on tuesday and 6 miles on friday

<em><u>Solution:</u></em>

Given that,

Rick jogged the same distance on tuesday and friday

Let "x" be the distance jooged on each tuesday and friday

He also jogged for 8 miles on sunday

Total of 20 miles for the week

Therefore, we frame a equation as,

total distance jogged = miles jogged on tuesday + miles jogged on friday + miles jogged on sunday

20 = x + x + 8

20 = 2x + 8

2x = 20 - 8

2x = 12

x = 6

Thus Ricky jogged 6 miles on tuesday and 6 miles on friday
