Answer:

56 riders

Step-by-step explanation:

With the proportion given, cross multiply, then divide:

  1. 70 × 80 = 5600
  2. 5600 ÷ 100 = 56
  3. So, the answer is 56 riders

I hope this helps!

Help please quueens i need help
Mrac [35]

Answer:

x = 3

Step-by-step explanation:

We can use the following equation to solve for x:

315=9x-27+8x+24+5x-17+2x+23\\315=(9x+8x+5x+2x)+(-27+24-17+23)\\315=24x+3\\312=24x\\13=x

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Veronika [31]

Answer:

<em>The area of the triangle DEF is 10.</em>

Step-by-step explanation:

<u>Area of a Triangle:</u>

A triangle of base B and height H (both must be perpendicular) has an area of:

\displaystyle A=\frac{BH}{2}

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

\displaystyle A=\frac{5*4}{2}=10

The area of the triangle DEF is 10.

Testing for a disease can be made more efficient by combining samples. If the samples from four people are combined and the mixt
Ilya [14]

Answer:

There is a 34.39% probability of a positive result for four samples combined into one mixture.

This probability is not low enough so that further testing of the individual samples is rarely​ necessary,

Step-by-step explanation:

There are only two possible outcomes. Either a sample tests positive, or it does not, so we use the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And \pi is the probability of X happening.

A number of sucesses x is considered unusually low if P(X \leq x) \leq 0.05 and unusually high if P(X \geq x) \geq 0.05

In this problem, we have that:

There are four samples, so n = 4

Each sample has a probability of 0.1 of being positive, so \pi = 0.1.

Assuming the probability of a single sample testing positive is 0.1​, find the probability of a positive result for four samples combined into one mixture.

If any sample is positive, the result of the four samples is positive. So this is P(X>0). Either the number of positive samples is 0, or it is greater than 0. The sum of the probabilities is decimal 1. So:

P(X = 0) + P(X>0) = 1

P(X>0) = 1 - P(X = 0)

In which

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

P(X = 0) = C_{4,0}.(0.10)^{0}.(0.9)^{4} = 0.6561

P(X>0) = 1 - P(X = 0) = 1 - 0.6561 = 0.3439

There is a 34.39% probability of a positive result for four samples combined into one mixture.

This probability if larger than 5%, so it is not low enough so that further testing of the individual samples is rarely​ necessary.
