T =70/r, where T is the number of years needed to double the population (or the capital, or any other thing) at the rate r (r , rate of growth)
 T = 710/4.6 = 15.21
T ≈ 15 years

Classify the triangle with angles with measures 20°, 133°, and 27° as acute, right, or obtuse. Please help will give 24 pts
ololo11 [35]
Acute is any angle that measures less than 90 degrees
so 20 degrees and 27 degrees would be acute
also any angle that measures more than 90 degrees is obtuse.
so 133 degrees is obtuse.
also just so you know right angles measure exactly 90 degrees.

William wants to invest $30,000 in a mutual fund.
Natali [406]

Answer:

He will have $39,750 at the end of five years.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

P = 30000, I = 0.065, t = 5

Interest earned:

E = P*I*t = 30000*0.065*5 = 9750

Total amount:

T = E + P = 9750 + 30000 = 39750

He will have $39,750 at the end of five years.

Professor Ivy has following scores on her final exams: 97 88 66 55 89 72 94 32 84 89 72 76 77 Express answers rounded correctly
Gre4nikov [31]

Answer:

The rest of the question:

<u>Find </u>Mean, Median, Mode, 25th Percentile, 75th Percentile, Maximum, Minimum, Range and IQR.

Let's begin by placing the data points in order from least to greatest:

32  55  66  72  72  76  77  84  88  89  89  94  97

n = 13

<u>1) Mean</u> sometimes called the average = the sum of the data over its number

Mean =( 32+55+66+72+72+76+77+84+88+89+89+94+97 )/13 =

         = 991/13 = 76.23 ≈ 76.2 (to the nearest tenth)

<u>2) Median</u> is the middle data point = 77

<u>3) Mode</u> is any number within a set that occurs the most often

Mode = 72 and 89

We will making a data in suitable form to find the remaining requirements:

<u>(32  55  </u><u>66  72</u><u>  72  76) </u> 77  <u>(84  88  </u><u>89  89</u><u>  94  97) </u>

<u>4) 25th Percentile </u>= Quartile 1 (Q1) which is the median of the first set of data

∴ 25th Percentile = (66+72)/2 = 138/2 = 69

<u>5) 75th Percentile</u>= Quartile 3 (Q3) which is the median of the second set of data

∴ 75th Percentile = (89+89)/2 = 89

<u>6) Maximum</u> = 97

<u>7) Minimum</u> = 32

<u>8) Range</u> = Maximum - Minimum = 97 - 32 = 65

<u>9) IQR (interquartile range)</u> = Q3 - Q1 = 89 - 69 = 20
