<span>A) −5x − 7 < −22 and −5x − 7 ≥ −3
Working;
Since the </span>−5x − 7 and <span>−22 have interchanged sides, the inequality sign also changes direction.
</span>
For part two, <span>−5x − 7 ≥ −3 remains unchanged.</span>
1/2 * 1/2 = 1/4 there is a 25% chance that they will both occur
Answer:
Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Step-by-step explanation:
To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Answer:
Lars works for the expected number of days but doesn't earn the expected amount of money.
Step-by-step explanation:
Let's check whether Lars works for the expected number of days this week by working as a nurse for 2 days and working as a lumberjack for 4 days. To do this, we substitute N=2 and L=4 into the first inequality:
N+L≤6
2+4≤6
6≤6
The true inequality shows that Lars works for the expected number of days this week by working as a nurse for 2 days and working as a lumberjack for 4 days.
Now let's check whether Lars earns the expected amount of money by working as a nurse for 2 days and working as a lumberjack for 4 days.
To do this, we substitute N=2 and L=4 into the second inequality.
216N+112L>950
216(2)+112(4)
>
950
880 >950
The false inequality shows that Lars doesn't earn the expected amount of money by working as a nurse for 2 days and working as a lumberjack for 4 days.
Lars works for the expected number of days but doesn't earn the expected amount of money.
