Answer: The probability is 1/8

Explanation:

Probability is a ratio of the number of relevant outcomes and total number of possible outcomes.

We are flipping the coin three times.

The number of relevant outcomes is 1 (one triple {Head, Head, Tail})

The number of all possible outcomes is the product of 2 possibilities (Head or Tail) on first toss, times another 2 on second, times another 2 on third, so 2^3 = 8.

The probability P = 1/8

Lim x-1 x2 - 1/ sin(x-2)

balu736 [363]

Answer:

$\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}=0$

Explanation:

Assuming the correct expression is to find the following limit:

$\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}$

Use the property the limit of the quotient is the quotient of the limits:

$\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}=\frac{\lim_{x \to 1}x^2-1}{\lim_{x \to 1}sin(x-2)}$

Evaluate the numerator:

$\frac{\lim_{x \to 1}x^2-1}{\lim_{x \to 1}sin(x-2)}=\frac{1^2-1}{\lim_{x \to1}sin(x-2)}=\frac{0}{\lim_{x \to 1}sin(x-2}$

Evaluate the denominator:

Since $\lim_{x \to1}sin(x-2)\neq 0$

$\frac{0}{\lim_{x \to1}sin(x-2)}=0$

Do the following measurements form a triangle? True or false 24°, 30° , 126°

Aleks04 [339]

Answer:

True

Step-by-step explanation:

The sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 °.

24+30+126=180

Solve the equation. 5x + 6 = 2(2x – 3) what dose x =

Lady_Fox [76]

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+6=2(2x−3)

Step 1: Simplify both sides of the equation.

5x+6=2(2x−3)

5x+6=(2)(2x)+(2)(−3)(Distribute)

5x+6=4x+−6

5x+6=4x−6

Step 2: Subtract 4x from both sides.

5x+6−4x=4x−6−4x

x+6=−6

Step 3: Subtract 6 from both sides.

x+6−6=−6−6

The frequency table below shows the antenna careers among the incoming class of first-year college students. Every student is ch

neonofarm [45]

To solve this you must use a proportion like so...

$\frac{part}{whole} = \frac{part}{whole}$

The total number of students that can be chosen are 4,663. This number will represent the whole of one fraction in the proportion. We want to know what percent probability out of these students are engineer, medical doctor/surgeon. This would be considered the part of this fraction. Sum the number of engineering students (615) with medical doctors/surgeons (723) to find this number

723 + 615 = 1,338 students that want to be an engineer or medical doctor/surgeon

Percent's are always taken out of the 100. This means that the other fraction in the proportion will have 100 as the whole and x (the unknown) as the part.

Here is your proportion:

$\frac{1,338}{4,663} =\frac{x}{100}$

Now you must cross multiply

1,338*100 = 4,663*x

133,800 = 4,663x

To isolate x divide 4,663 to both sides

133,800/4,663 = 4,663x/4,663

28.7 = x

This means that there is a 28.7% of a student with the intent of becoming an engineer or a medical doctor/surgeon to be chosen at random

Hope this helped!
