Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
Answer:
55 and 55 or 70 and 40
Step-by-step explanation:
A triangle has 180o and an isosceles triangle has two angles that are the same. As 70 is less than half, we have a couple of possible solutions to this. So one possible solution is 70-55-55. So the other possible solution is 70-70-40.
Answer:
The probability that their mean life will be longer than 13 years = .9943 or 99.43%
Step-by-step explanation:
Given -
Mean
= 15 years
Standard deviation
= 3.7 years
Sample size ( n ) =22
Let
be the mean life of manufacturing items
the probability that their mean life will be longer than 13 years =
=

= 
=
Using Z table
= 1 - .0057
= .9943
Answer:
Step-by-step explanation:
<u>Given inequality</u>
- |x+6| - 12 < 13
- |x+6| < 13 + 12
- |x+6| < 25
To solve this inequality graphically you need two graphs according left and right sides of inequality
<u>So the graphs should be:</u>
