I need help please it gives a hint I don’t get it

devlian [24]

Answer:

Lower quartile: 72

Upper quartile: 84

Step-by-step explanation:

Follow the instructions in the hint to solve the problem.

First, divide the data set into halves:

70, 70, 72, 75, 79

80, 80, 84, 89, 95

Now, find the median of the two sets. The median of set #1 is 72, as that is the number in the middle of the data.

The median of set #2 is 84 for the same reason.

Upper and lower quartiles are just different words for upper and lower medians. The upper quartile is the higher number, and the lower quartile is the lower number.

Determine whether the point (1, 5) is a solution to the system of equations. Explain your reasoning in complete sentences. graph

sergejj [24]

According to your text first equation is
y = 3x+2
second equation is
y = Ix-1I + 1

Definition of our absolute value Ix-1I is
1) we take x-1 with condition x-1≥0 => x≥1
2) we take -(x-1) = -x+1 with x<1

Let's form the first system with condition x≥1
y= 3x+2 and y=x-1+1=> y=x
If the left sides of the equations are equal, than the right sides are equal too
3x+2=x => 3x-x=-2 => 2x=-2 => x=-1
This solution we can't accept because it does not meet the condition
x≥1
Lets's form the second system with condition x<1
y=3x+2 and y= -x+1+1 =. y = -x+2
In the same way as previous the right sides are equal =>
3x+2=-x+2 => 3x+x = +2-2 => 4x=0 => x=0
We accept this solution bacause its meet with condition x<1
When we replace this solution in equation y=3x+2 we got
y=3*0+2=2 Only one solution is (x,y) = (0,2)
Good luck !!!!!

In a recent year, 19.4% of all registered doctors were female. If there were 52,500 female registered doctors that year, what wa

sukhopar [10]

Answer: 10,185 registered female doctors.

Step-by-step explanation: We basically want to find how many females were doctors, if 19.4% of the 52,500 females were registered doctors. Basically we want to find 19.4% of 52,500. We will write an equation that works to solve this problem.

19.4/100 = x/52,500 (This equation represents that 19.4% out of 100% is x out of the 52,500 registered doctors.) Solve for x.

19.4/100 x 52,500 = x/52,500 x 52,500.

(19.4 x 52,500 = 1,018,500/100 = 10,185. And, x/52,500 x 52,500 = x.

10,185 = x.

So, 19.4% of all registered doctors would be 10,185 females out of 52,500 females.
