Answer:

<em>D. y=-3x</em>

Step-by-step explanation:

<u>Direct Proportion</u>

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

\displaystyle \frac{y}{x}=k

Where k is the constant of proportionality.

Solving for y:

y=kx

The only choice representing a direct proportion is:

D. y=-3x

which function has the greatest rate of change? A. y = 7/6x + 2/3 B. y = 7/5x + 7/5 C. y = 6/5x + 11/5 D. y = 5/4x + 15/4
ddd [48]

Answer:

Step-by-step explanation:

In y = mx + b form, the slope can be found in the m position

y = 7/6x + 2/3......slope(m) = 7/6 or 1.167

y = 7/5x + 7/5....slope(m) = 7/5 or 1.4

y = 6/5x + 11/5...slope(m) = 6/5 or 1.2

y = 5/4x + 15/4.....slope(m) = 5/4 or 1.25

so the greatest rate of change would be B. y = 7/5x + 7/5 with a slope of 7/5

When calculating interest accrued, you should ____.
Ber [7]

Answer:

(B)

Step-by-step explanation:

Interest accrued is defined as the interest which we need to pay at the end of some time span. The interest accrued may be on daily basis as well as on monthly basis.

For calculating the interest accrued, we first multiply the principal amount with  APR, this will give the interest of one year.

Then we will multiply it with the  no. of months on which the interest is being calculated and divide it by total no. of months.

This will give the interest accrued every month.

When calculating interest accrued, you should <u>multiply the principal by the APR and number of months, then divide by the total number of months in the year.</u>

dentify which of these types of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine her a
Bess [88]

Answer:

The sampling method used is a stratified sampling method

Step-by-step explanation:

sampling is the selection of a predetermined representative subpopulation from a larger population, to estimate the characteristics of the whole population.

Stratified sampling: Here, the total population are divided into subcategories (strata) before sampling is done. The strata are formed based on some common characteristics. In our example, the times of the day (morning, afternoon and evening) has widely varying atmospheric conditions which will add biases to the measurement of air quality. For example, the air in the morning if compared to the afternoon in an industrial area may be purer because of minimal industrial activity, hence effective comparison will be made by stratification.
