Answer:
A box and whisker plot is a summarized graph summarizing, the five numbers, minimum, lower quartile, median, upper quartile and maximum. While the portion covering lower quartile, median and upper quartile appears as a box, minimum and maximum data points show up as whiskers at the two ends (see figure below)
Step-by-step explanation:
Let
x = number of registered doctors
It's known that 21.3% of all registered doctors were female, that is:
21.3% of x were female, or:
21.3/100 x = 0.213x
We are given this number of female doctors, thus:
0.213x = 46,700
Dividing by 0.
Answer:
function 2
Step-by-step explanation:
After 5 tests, her average was 88. To have a seven-test average of 90, the total must be:
Her average after 5 tests was 88. Her total score on the 5 tests is:
Subtract:
Find the average by dividing by 2:
Her average must be 95
Answer:
For A:
Draw a number line with a dot on 3
For B:
Draw a number line connecting points at -3 and 10/3. Open dot an 10/3, and closed dot at -3
Intersection: x = 3
Step-by-step explanation:
A = {x : -8 < 5x + 2 = 17, x belongs to I}
-8 < 5x + 2 = 17
-10 < 5x = 15
-2 < x = 3
It's only x = 3
B = {x : -2 <= 7 + 3x < 17, x belongs to R}
-9《3x < 10
-3《x < 10/3
Since there's only one value in A and that also lies in B, the intersection is at x = 3
