Hi
Step-by-step explanation:
Suppose that 5% of athletes at a certain university are using steroids or other
performance-enhancing drugs (PEDs). Unfortunately, the tests used to detect PEDs
aren't perfect. Suppose that 3% of athletes who are not using PEDs will test positive
and be accused of using PEDs. Meanwhile, 1% of athletes who are using PEDs will test
negative and escape detection. Calculate the probability that a randomly selected
athlete will test positive.
Answers
Answer:
There is a 8.11% of any randomly selected athlete to test positive.
Step-by-step explanation:
To make it easier, let's assume there are 100 athletes
5/100 have it
3/95 do not have it, but will test positive
1% of the 5 athletes who are using PEDs = 0.05%
This means that 4.95/100 will test positive
3/95 = 3.16%
(rounded, if you need a more precise answer, it's 3.1578947368421053)
3.16% + 4.95% = 8.11%

Answers
Answer:
x ≈ 36.09
Step-by-step explanation:
Complete question
Use △DEF, shown below, to answer the question that follows: Triangle DEF where angle E is a right angle. DE measures x. DF measures 55. Angle D measures 49 degrees. What is the value of x rounded to the nearest hundredth? Type the numeric answer only in the box below.
According to the diagram
m<E = 90 degrees
m<D = 49 degrees
DF = 55 = hypotenuse
DE = x = adjacent
EF = opposite
According to SOH CAH TOA identity;
Cos theta = adj/hyp
Cos m<D = DE/DF
Cos 49 = x/55
x = 55cos49
x = 55(0.6561)
x = 36.0855
x ≈ 36.09 (to the nearest hundredth)
Answer:
x ≈ 36.09

A box is filled with 9 yellow cards, 5 red cards, and 6 blue cards. A card is chosen at random from the box. What is the probability that it is a yellow or a blue card? Write your answer as a fraction in simplest form
Answers
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
9 + 5 + 6 = 20 (how many cards there are altogether)
9 yellow + 6 blue = 15 (how many cards are either yellow or blue)
so:
[tex]\frac{15}{20}[/tex]
simplified:
[tex]\frac{3}{4}[/tex]
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
There are 20 total cards ( 9 + 5 + 6). 15 of them are yellow or blue(9 + 6). So, the fraction is [tex]\frac{15}{20}[/tex]. [tex]\frac{15}{20}[/tex] simplifies to [tex]\frac{3}{4}[/tex].

a) 3= x + 7
b) -7a-49
Answers
Answer: b im pretty sure hope this helps :)
Step-by-step explanation:
Answer:
A: x = -4
B: a = -7 (I'm assuming the '-' in front of 49 was supposed to be an '=')
Step-by-step explanation:
A: You need to group the like terms together, and isolate the variable, which in this case is x.
Take the 7 over to the other side, so the equation looks a little bit like this.
3-7 = x.
3-7 is -4, so we've gotten our answer.
x = -4.
B: -7a = 49.
When two negative numbers are multiplied together, the product becomes positive.
49 is 7x7.
-7 times -7 would be 49.
So, in this situation, a would be -7.
a = -7.
