Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, we have that:

  • The rate in Brazil is of 5 \times 10^4.
  • The rate in the United States is of 14000 = 1.4 \times 10^4.

Hence, the rate between the consumption in Brazil and in the United States is given by:

r = \frac{5 \times 10^4}{1.4 \times 10^4} = 3.57

Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

What is the area of this trapezoid?
slamgirl [31]
Area of rectangle in the middle = 12 * 9 = 108
Area of left triangle = .5 * 2 * 9 = 9
Area of right side triangle = .5 * 5 * 9 = 22.5

Total area = 108 + 9 + 22.5 = 139.5 square inches

Need help finding the equation of the line in slope intercept form
Scilla [17]

Answer:

Step-by-step explanation:

Equation: y=mx+b

m is the gradient while b is the y-intercept

Let's first find the slope (also known as the gradient) by choosing two points.  

The formula to find the slope is change in y divided by change in x.  

So two points are: (-2,0) and (0,5)

Change in y: 5-0 (we use the y-coordinates)

Change in x: 0--2 (0+2) (we use the x-coordinates)

So: 5-0= 5 and 0+2= 2 which means 5 divided by 2

Slope= 5 over two

To find the y-intercept we need to see where the line crosses the y-axis which would be at (0,5)

So: y-intercept is  5 as that's where the line crosses the y-axis.

Equation now: y= 5 over 2x +5

37% of women consider themselves fans of professional baseball. you randomly select six women and ask each if she considers hers
valina [46]

Answer:

(a) 2.22

(b) 1.3986

(c) 1.183

Step-by-step explanation:

Let <em>X</em> denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, <em>p</em> = 0.37.

A random sample of <em>n</em> = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable <em>X</em> thus follows a binomial distribution with parameters <em>n</em> = 6 and <em>p</em> = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

\text{Mean}=np=6\times 0.37=2.22

(b)

Compute the variance of the binomial distribution as follows:

\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986

(c)

Compute the standard deviation of the binomial distribution as follows:

\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183

Five times a number which is 3 more than h. Write this as an expression.
ladessa [460]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

So, let's start off with h

The expression needs to be '3 more than h'

This can be written as:

h + 3

The expression also needs to be 'five times' this value

This can be written as:

5(h + 3)

That would be your answer ^^

Have A Nice Day ❤
