A medical company claims it has a test that is 95% effective in determining whether an athlete is using a steroid or not. Suppose this test is given to a group of athletes in which 10% of the athletes are using steroids.What is the probability that a randomly chosen athlete actually uses steroids, given that the athlete's test is positive?
Answer:
Probability = 10% = 1/10
Step-by-step explanation:
Prob (Medical company determines steroids use) = P(D) = 95%
Prob (Group athletes use steroids) = P(S) = 10%
Prob (athlete use steroids & medical determines steroid use) = P (D ∩ S) = 95% x 10% = 9.5%
Conditional Prob [ P (S) I P (D) ] = P (S ∩ D) / P (D)
= 9.5% / 95% = 10% , ie = 1/10
The scatter plot shows the number of gallons of gas nicks car used to travel different numbers of miles
A scatterplot shows the number of miles driven versus the gallons of gasoline remaining in the gas tank of a car. Which correlation best describes the relationship shown on the scatterplot?
Answer:
Negative correlation
Step-by-step explanation:
The kind of relationship which exists between two variables can be obtained whwn plotted in a graph such that we can visually access the data and note its trend. Datasets with fit lines trending downward will always have a slope value which is negative. In the scenario above, gallon of gasoline falls as the number if miles driven increases. This is a very reasonable relationship. And thus correlation between Both variables will be negative

Joe and Steve went to a chocolate shop and got some fudge. The fudge cost $32 per kilogram. Joe ordered 75 grams of fudge. Steve ordered 235 grams of fudge. How much did each person pay? How much MORE did Steve pay than Joe?
Answer: Joe paid $2.4; Steve paid $7.52
Steve paid $5.12 more than Joe
Step-by-step explanation:
Cost of I Kg fudge = $32
But we know that 1 kg =1000g
That is to now say that
Cost of 1000g of fudge = $32
a)
If Joe ordered 75 grams of fudge then he paid
Now 1000g of fudge = $32
75g of fudge will cost =75 x 32 /1000 =$2.4
also .
b) 235 grams of fudge ordered by Steve will cost
235 x 32 / 1000=$7.52
Therefore, Steve paid $5.12 ($7.52-$2.4) more than Joe

Answer:
Step-by-step explanation:
1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm
Area: 8cm x 3cm = 24cm
2. Perimeter: 5m + 5m + 5m + 5m = 20m
Area: 5m x 5m = 25m
3. Perimeter: 4m + 4m + 18m + 18m = 44m

Given square WXYZ. If ZY = 20, find WV. Write your response in the form WV=_____.
Answer:
14.14
Step-by-step explanation:
Recall :
The sides of a square are always equal ;
Since all sides are equal, the the diagonal of the square will be :
XZ² = XY² + WX²
XZ² = 20² + 20²
XZ² = 400 + 400
XZ² = 800
XZ = √800
XZ = 28.28
WY = XZ
WV = 1/2 WY
WV = 1/2 * 28.28
WV = 14.14

Answer:
1. 96
2. x= 10.909 (10.91 (rounded))
Step-by-step explanation:
1. You can break the figure into 3 parts, a triangle and 2 rectangles
For the triangle, we have this information:
height is 3
length is 8
angle is 90 (right angle)
area = 0.5 * 3 * 8 * sin(90)
area is 12
For the two rectangles, just multiply the length * width
5 * 4= 20
8 * 8= 64
Then add them ALL together
12 + 20 + 64 = 96
2. x = √(12^2 - 52^2)
x= 10.09
(10.91(rounded))
