Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test t

White raven [17]

Answer:

a. the Student's t-distribution with 124 degrees of freedom

Step-by-step explanation:

We have no information about the standard deviation of the population, just for the sample, which means that the student's t-distribution is used.

Degrees of freedom

Sample size subtracted by 1.

125 households were sampled.

125 - 1 = 124 degrees of freedom.

So the correct answer is:

a. the Student's t-distribution with 124 degrees of freedom

Steve has x+500 marbles
richard has x marbles

if steve gives richard 300 marbles then
x+500-300 x+300
so x+200 and x+300
richard has more and by 100

I need help finding if it’s either SOH, CAH or TOA and the indicated side of the triangle, thank you!

Brilliant_brown [7]

Answer:

$\huge\boxed{IJ \approx 2.01}$

Step-by-step explanation:

In order to find the side mentioned (IJ), we need to use SOH CAH TOA.

SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:

Sin = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.

Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.

Our equation is now this: $\text{sin(42)} = \frac{x}{3}$

Let's now solve for x.

$\text{sin(42)} = \frac{x}{3}$
$3 \cdot \text{sin(42)} = x$
$\text{sin(42)} \approx 0.67$
$3 \cdot 0.67 \approx 2.01$

Therefore, the length of IJ will be around 2.01.

Hope this helped!
