Answer:

20.42 is your answer

Step-by-step explanation:

First change all mixed fraction into improper fractions

lorasvet [3.4K]

The answer is 0.7.

Given,

On the off chance that the odds he will get a hit is 0.3

p = 0.3,

the odds he won't are 0.7

i.e.,

q = 1 - 0.3

=0.7

What is probability ?

  • Probability is synonymous with possibility. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one.
  • Probability has been introduced in mathematics to predict the likelihood of occurrences occurring.
  • Probability is defined as the degree to which something is likely to occur. This is the fundamental probability theory, which is also utilized in probability distribution, in which you will learn about the possible results of a random experiment.
  • To determine the likelihood of a particular event occurring, we must first determine the total number of alternative possibilities.

Find the equations of all lines tangent to y = 9–x^2 that pass through the point (1, 12). ...?
Oksanka [162]
The slope of the tangent at a given point can be found by differentiating the given equation and substituting the value of x at the point as such:
y = 9 - x²
dy/dx = -2x; x = 1
dy/dx = -2

For a line with the slope of -2 and passing through point (1 , 12)
y -12 = -2(x - 1)

Find the component form of the resultant vector
Lera25 [3.4K]
Answer to problem 1 is {-144,-192}
Answer to problem 2 is {-12,-12}

-------------------------------------------------

Explanation:

Vector u is given to be u = {-18,-24}
To compute the vector 8*u, we multiply both sides by 8 and multiply each coordinate by 8
The rule I'm using is if u = (a,b) then k*u = (k*a,k*b)

So,
u = {-18,-24}
8*u = 8*{-18,-24}
8*u = {8*(-18),8*(-24)}
8*u = {-144,-192}

Problem 2 is handled the same way
f = {-2,-2}
6*f = 6*{-2,-2}
6*f = {6*(-2),6*(-2)}
6*f = {-12,-12}
