Theoretical probability is the same thing as experimental probability. True False

1 answer:

6 0

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. So the answer is FALSE.

Use the information in the table. You are making a circle graph showing the total number of successful United States space launc

timama [110]

Answer:

52.9°

Step-by-step explanation:

step 1

we know that

The total number of successful United States space launches that happened in the years 1957-1995 is equal to

$15+470+258+153+146=1,042$

step 2

The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

$153$

step 3

The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

$\frac{153}{1,042}(100)=14.68\%$

step 4

Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989

we know that

In a circle, 360 degrees represent the 100%

using proportion

Find out the measure of the central angle by a percentage of 14.68%

$\frac{360^o}{100\%}=\frac{x}{14.68\%}\\\\x=360^o(14.68\%)/100\%\\\\x= 52.9^o$

Step-by-step explanation:

Apply the fractions formula for subtraction, to

14−13

and solve

(1×3)−(1×4)4×3

=3−412

=−112

Therefore:

14−13=−112

Use implicit differentiation to find an equation of the tangent line to the curve at the given point.

kenny6666 [7]

Hello:
Use implicit differentiation : y sin 12x = x cos 2y
y' sin12x+12ycos12x =cos2y -2x y'sin2y
when : x = π/2 and y =π/4

y' sin12(π/2) +12(π/4)cos12(π/2) =cos2(π/4) -2(π/2) y'sin2(π/4)
y' sin(π/6) +(π/3)cos(π/6) =cos(π/2) - π y'sin(π/2)

y' (1/2) +(π/3)(√3/2) = - π

y' (1/2) =-(π/3)(√3/2) - π
y' = -π (1+√3)/3
an equation of the tangent line is : y- π/4 = ( -π (1+√3)/3)(x-π/2)
