Jeremiah always rides his bike to and from work. The total
Katen [24]

From the computation done, the total kilometers that he uses last month will be 262.8 kilometers.

The total length of a trip to and from work is 14.6 kilometers and last month, Jeremiah worked 18 days.

Therefore, the kilometers that he rode his bike to and from work last month will be;

= 14.6 × 18.

= 262.8 kilometers.

The function f is such that f(x)=4x-1 find f^-1(x)
zvonat [6]
Let y=4x-1
The inverse is basically expressing x in terms of y.
y=4x-1  =>
y+1=4x
x=(y+1)/4
Since the inverse is still a function of x, we only have to interchange x and y
inverse of f(x) = f^-1(x) = (x+1)/4

As a result of medical examination, one of the tests revealed a serious illness in a person. This test has a high precision of 9
Elina [12.6K]

Answer:

0.0098

Step-by-step explanation:

Given,

  • Probability of test is positive if the person has disease, P(T/D)=0.99

Probability of test is negative if the person has disease,

P(T'/D) = 1-0.99 = 0.01

  • Probability of test is negative if the person hasn't disease, P(T'/D')= 0.99

Probability of test is positive if the person hasn't disease,

P(T/D') = 1 - 0.99 = 0.01

  • Probability of occurrence of disease, P(D) = 0.0001

Probability of not occurrence of disease,

P(D) = 1 - 0.0001 = 0.9999

Probability that test will be positive either disease is present or not,

P(T) = P(T/D).P(D)+P(T/D').P(D')  

      =0.99 x 0.0001 + 0.01 x 0.9999

      = 0.000099 + 0.009999

      = 0.010098

So, the probability that the person will have disease if the test is positive,

P(D/T)\ =\ \dfrac{P(T/D).P(D)}{P(T)}

           =\ \dfrac{0.99\times 0.0001}{0.010098}

            = 0.0098

So, the required probability will be 0.0098.

What °(degree) dose a isoscele,scalene and equilateral have to be to make it acute, obtuse or right?
cestrela7 [59]
Ok so defenitions
isosceles means 2 angles or sides are equal legnth

scaleen means no sides or angles are eaqual measure

equilateral means all sides and angles are equal measure
(since all side equal measure, all angles are always 60)



acute means all angles are less than 90
obtuse means at least one angle is more than 90
right means that  1 angle is 90 degrees


ok so
isosceleese
for it to be acute, maybe make the angles 50,50,80
obtuse 40,40,100
right 90,45,45

scaleene
acute, 30,70,80
obtuse 100,30,50
right, 90,40,50

equilateral all angles are automatically equal to 60 so
acute: 60,60,60
obtuse: not possible
right: not possible
