1. If there it is a straight line, it is linear, and if it is increasing at a constant rate of change, it is linear.
2. A company would prefer profits that show exponential growth because even though it starts out slow, it quickly gains more and greatly overcomes the sum of what linear profits would.
3. An example of exponential growth would be interested in a savings account.

MrRa [10]

Answer:

676 assuming the population is 3800 in 2019. If it's a different year then change t.

Step-by-step explanation:

$P(t) = P_{0} (1+r)^t \\\\P(6) = 3800(1-.25)^6 \\=P(6) = 3800(.75)^6\\=676$

A triangular playground has angles with measures in ratio 8: 3: 9 what is the measure of the smallest angle

maria [59]

8x + 3× + 9x = 180

20x = 180
x = 180/20
x = 9

The smallest angle is: 3×9 = 27 degrees

Note: 180 degrees is the sum of angles in a triangle

PLS HELP ME WITH THIS !!

Mashutka [201]

Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p

part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2

Fred and Ted are interested in the average height of NC State students. They randomly sample students from NC State and construc

Nataly [62]

Answer:

a. Fred's margin of error is larger than Ted's.

Step-by-step explanation:

Margin of error of a confidence interval:

$M = z\frac{\sigma}{\sqrt{n}}$

In which z is related to the confidence level(the higher the confidence level the larger the value of z) $\sigma$ is the standard deviation of the population and n is the size of the sample.

From this, we have that:

A higher confidence level leads to a larger margin of error.

A larger sample size leads to a smaller margin of error.

In this question:

Same confidence level.

Fred's sample is smaller, so his margin of error will be larger.

The correct answer is given by option a.
