Answer:

<em>x </em>equals 3.6.

Step-by-step explanation:

A way to solve this equation is to preform the inverse operations on both sides.

1. Add 19 to -19 and 5: 5<em>x </em>+ 6 - 19 + 19 = 5 + 19 ---> 5x + 6 = 24

2. Subtract 6 from 6 and 5: 5x + 6 - 6 = 24 - 6 ---> 5x = 18

3. Divide 5x and 18 by 5: 5x / 5 = 18 / 5 ---> x = 3.6

4. 3.6 is the answer.

To prove it, substitute x with 3.6 in the equation: 5 · 3.6 + 6 - 19 = 5

I hope this made sense and helped you a lot! :)

During a bike challenge, riders have to collect various colored ribbons. Each 1/2 mile they collect a red ribbon, each 1/8 mile

Inessa [10]

Answer:

Hence, a blue and a green ribbon will be collected at the 3/4 marker.

Step-by-step explanation:

During a bike challenge, riders have to collect various colored ribbons.

Each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 mile they collect a blue ribbon.

We are asked to find which colors of ribbon is collected at the 3/4 mile marker.

since 1 red ribbon is collected at 1/2 mile the next ribbon will be collected at 1 mile.

so he will not reach at the 3/4 marker to get a red ribbon

Hence, no red ribbon will be collected at 3/4 marker.

Now each green ribbon is collected at 1/8 mile.

since, 1/8+1/8+1/8+1/8+1/8+1/8=6/8=3/4

i.e. adding 1/8 6 times we get 3/4

Hence, he will reach the 3/4 marker and get a green ribbon.

Now we are given that each blue marker is obtained at 1/4 marker.

since 1/4+1/4+1/4=3/4

Hence, a blue ribbon will be given at a 3/4 marker.

Hence, a blue and a green ribbon will be collected at the 3/4 marker.

Please help me prove this theorem thing. I'll give yuh mind kisses <3 have a good day luvlies

lesantik [10]

Answer:

∠ 1 = 20 x + 5

∠ 2 = 24 x - 1

If lines l and m are parallel:

∠ 1 + ∠ 2 = 180°

20 x + 5 + 24 x - 1 = 180

44 x + 4 = 180

44 x = 180 - 4

44 x = 176

x = 176 : 44

x = 4°

Your welcome again :)

If the expected value (the mean) of successes in a binomial experiment of 100 trials is 55. Which of the following are not true?

Elis [28]

Answer:

All of the statements are true

Step-by-step explanation:

Given that :

Number of trials (n) = 100

Expected number of successes = 55

The number of successes of the 100 trials :

Number of successes / number of trials = 55 / 100 = expected number of successes / n = 55/ 100 = 0.55

Using Normal approximation :

Standard deviation (σ) = √(npq) ; q = 1 - p = 1 - 0.55 = 0.45

σ = √(100 * 0.55 * 0.45) = √24.75 = 4.975

The probability distribution of x = B(n, p) = x = B(100, 0.55)

Using approximation ; N(p, σ) = N(55, 4.97)

Hence, All of the statements are true
