Select the three ratios that represent the number of red cars to blue cars.
Lorico [155]

Three ratios that represent the number of red cars to blue cars are

2 : 3

6 : 9

8 : 12

\texttt{ }

<h3>Further explanation</h3>

<u>Given:</u>

Number of Red Cars = 4

Number of Blue Cars = 6

<u>Asked:</u>

Ratio = ?

<u>Solution:</u>

<em>Let:</em>

<em>Number of Red Cars = R</em>

<em>Number of Blue Cars = B</em>

The ratio that represent the number of red cars to blue cars is :

R : B = 4 : 6

We can find other ratio by dividing or multiplying the above comparison with the same number :

R : B = (4/2) : (6/2) = 2 : 3

R : B = (4 \times 2) : (6 \times 2) = 8 : 12

R : B = (4 \times \frac{3}{2}) : (6 \times \frac{3}{2}) = 6 : 9

\texttt{ }

<h3>Conclusion:</h3>

Three ratios that represent the number of red cars to blue cars are:

  • 2 : 3
  • 6 : 9
  • 8 : 12

Write the word sentence as an equation. Then solve.<br><br> 10 more than a number c is 3.
ira [324]

Answer:

10+c=3

Step-by-step explanation:

to solve this you would then subtract 10 from both sides, to get c by itself.

3-10= -7

Your answer would be -7 and the equation would be 10+c=3.

Students were packed shoulder to shoulder in a gym for a pep rally. The students were in a rectangular shaped area of 7,500 ft2.
hram777 [196]

Answer: 1527

Step-by-step explanation:

Total Area = 7500 ft^2

Area covered by one student = Area of one circle

                                                   = π*r^2

r = radius of circle = 2.5/2 = 1.25 ft

Area covered by one student = π*1.25^2 = 4.91 ft^2

Number of students who can fit into total area = Total Area/Area covered by one student

Number of students who can fit into total area = 7500/4.91 = 1527.49

Hence the answer is 1527 students

In a survey of 225 art students 28% reported that their favorite color is blue. What is the margin of error for the sample?
ipn [44]
Margin of error is important in determining the probability as it gives realistic data for the distribution. The formula to be followed for margin of error is m% = z* sqrt (p*(1-p))/n where p is the % positive outcome, n is the sample size and z* is a constant dependent to % confidence level. Substituting, m% = z* (0.03). Level of confidence is not given but assuming at95% CF, m% = 6%
