If Q is the midpoint of PR, find x when PR=2x and PQ=2x-12.

frozen [14]

Answer: x=12

Step-by-step explanation:

You start with: $2x\neq 2x-12$

The segment PQ is half of PR, so to make both sides equal the PQ side must be doubled.

$2x=4x-24$

Then all x-values should be put on one side of the equation.

$2x-4x=-24$

Combine like terms.

$-2x=-24$

Then simplify. $x=12$

What is the value of the tangent of

kiruha [24]

Answer:

Step-by-step explanation:

With reference < H

perpendicular (p) = 12

base (b) = 5

so now

tangent of < H

= p / b

= 12 / 5

4.) Admission to the State Fair is $6 and each ride costs $3. Ella wants to spend less than $40. What is the maximum number of r

Radda [10]

Answer:

11 rides

Step-by-step explanation:

First Step - Subtract 6 from 40 because that will not be of use for now.

40-6=34

Next Step - divide 34 by 3 to find the number of rides.

(you will end up with a decimal so I rounded it up to a whole number.)

34/3=11 (rounded)

The final answer is 11 rides.

Hope this helped :)

Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.

posledela

Answer: 31.25%

Two ways to solve this problem:

#1: Use the formula: $P(X=x)={n}Cx_{} *p^{x}*(1-p)^{n-x}$

#2 Use a graphing calculator and use the function binompdf(n, p, x)

x = 3
n = 6
p = 0.5

#1: Formula:

$P(X=3)=_{6}C_{3}*0.5^{3} *(1-0.5)^{6-3}=\frac{6!}{3!(6-3)!} *0.5^{3} *0.5^{3}\\=\frac{6!}{3!*3!} *0.5^{3} *0.5^{3}=20*0.125*0.125=0.3125$

#2: Faster method

binompdf(6, 0.5, 3) = 0.3125
