liraira [26]

Using a confidence interval, we have that:

a) The range is from 48.8% to 51.2%.

b) Between 125,000 and 131,000 adults are registered organ donors.

<h3>What is a confidence interval?</h3>

A confidence interval is given by the <u>estimate plus/minus the margin of error</u>.

For this problem, we have that:

  • The estimate is of 50%.
  • The margin of error is of 1.2%.

The bounds of the range are given as follows:

  • 50% - 1.2% = 48.8%.
  • 50% + 1.2% = 51.2%.

Hence the range is from 48.8% to 51.2%.

<h3>What are the total numbers?</h3>

We have to find <u>48.8% and 51.2% of 255,200,373</u>, hence:

  • 0.488 x 255,200,373 = 124,537,782.
  • 0.512 x 255,200,373 = 130,662,591.

Rounded to hundredth thousand, between 125,000 and 131,000 adults are registered organ donors.

What is the domain of the function
Ksenya-84 [330]

Answer:

x\geq -6

Step-by-step explanation:

The domain of a function is all of the values that x can be under that specific function. In this case, we're asking what values of x allow \sqrt{\frac{1}{3} x+2} to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to 0, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for x:

\frac{1}{3}x+2\geq 0

Solving this inequality, we get:

\frac{1}{3}x+2\geq 0

\frac{1}{3}x\geq -2 (Subtract 2 from both sides of the inequality to isolate x)

x\geq -6 (Multiply both sides of the inequality by 3 to get rid of x's coefficient)

Hope this helps!

Factor x3 – 7x2 – 5x + 35 by grouping. What is the resulting expression?
Aliun [14]

Answer:

(x-7)(x-\sqrt{5})(x+\sqrt{5})

Step-by-step explanation:

The given expression is

x^3-7x^2-5x+35

Factor the first two and the last two.

x^2(x-7)-5(x-7)

(x-7)(x^2-5)

Apply difference of two squares to the leftmost factor.

(x-7)(x-\sqrt{5})(x+\sqrt{5})
