Answer:

It is stratified random sampling.

Step-by-step explanation:

Stratified random sampling is a method of sampling that involves the division of a population into smaller sub-groups known as <em>strata.</em>

The strata are formed based on members' shared attributes or characteristics, in this case their race.

Stratified random sampling is also called <em>proportional random sampling</em> or <em>quota random sampling</em>

Answer:

D is correct

Step-by-step explanation:

A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis.  This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.

"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .
Alinara [238K]

Answer:

x intercept

y = 0 \\ 0 =  \frac{1}{3} x + 3 \\  \frac{1}{3} x =  - 3 \\ x =  - 9

y intercept

x = 0 \\ y =  \frac{1}{3}  \times 0 + 3 \\ y = 3

Aneli [31]
For the answer to the question above, your end goal is to have $6,000 total in 12 months. since you have $2400 already you can subtract that from 6,000 leaving you with $3600 over the course of 12 months. since you already put $150 in a month over the course of 12 months you would have $1800 which is only half of the goal of $3600. in order for you to put in $3600, you would have to put an additional 150 in your savings along with your regular 150 making Letter B the answer.

1 tbs : 3 tsp

5 \frac{2}{3}  =  \frac{17}{3}  \\  \frac{17}{3} tbs \:  = 3( \frac{17}{3} )tsp \\  \frac{17}{3} tbs = 17tsp

Always start by converting mixed numbers into fractions;

multiply the whole number part by the denominator (under part) of the fraction part and add this to the numerator (upper part);

Then simply apply the ratio.
