For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
Answer:
-5, -4 , -3 , -2, -1, 1, 2 , 3, 4, 5
Step-by-step explanation:
Yes Because there aremultiple place for the 102 degrees angle
Answer: 34%
Step-by-step explanation:
Creating a table with the information will help us.
<6h of sleep - 75% reported tired | 25% reported ok
>6h of sleep - 70% reported ok | 30% reported tired
80% of all interns received <6h of sleep
Let's imagine that we have 100 interns at this hospital
<6h | >6h Total
Tired 75% of 80 30% of 20
ok 25% of 80 70% of 20
Total 80 | 20 100
<6h | >6h Total
Tired | 60 | 6 66
ok | 20 | 14 34
Total | 80 | 20 100
what percent of the interns report no feelings of tiredness during their shifts?
34/100 = 34%
Answer:
3.5 hours
Step-by-step explanation:
8.75/2.5=3.5
