Answer:

2.23

Step-by-step explanation:

The reason why this is your answer is that this number is between 2 2/10 and 2 3/10. That means that turned into decimals, this number will be somewhere between 2.2-2.3

Now, we can see that this is 3 units away from 2 2/10 on the number line, which tells us that the decimal is 2.23

So hence, your answer is 2.23

Gina invests $1,677 in an account paying 8.61% simple interest annually. How much interest has Gina gained after six years? a. $

enot [183]

Answer:

Option (c) is correct.

The interest gained by Gini in 6 years is $ 866.34

Step-by-step explanation:

Given: Gina invests $1,677 in an account paying 8.61% simple interest annually for 6 years.

We have to calculate the interest gained by Gina in 6 years.

Using formula for simple interest

$S.I.=\frac{P\times I\times T}{100}$

Where,

S.I = simple interest

P is principal

R is interest rate

T is time

Given : P = $ 1677

R = 8.61%

T = 6 years

Substitute, we get,

$S.I.=\frac{1677\times 8.61\times 6}{100}$

Simplify, we get,

S.I. = $ 866.3382

Rounding off to nearest hundred we get, Interest is $866.34

Thus, the interest gained by Gini in 6 years is $ 866.34

West of a city, a certain eastbound route is straight and makes a steep descent toward the city. The highway has a 12% grade, wh

Masteriza [31]

Answer:

120 ft

Step-by-step explanation:

A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.

x/1000 = 12/100

x = 120 ft

Consider a box that contains 14 red balls,12 blue balls,and 9 yellow balls.A ball is drawn at random and the color is noted and

allochka39001 [22]

Answer:

a. The probability of both balls are blue is $\frac{144}{1225}$ .

b. The probability of getting first red and second yellow ball is $\frac{18}{175}$ .

Step-by-step explanation:

It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is

$14+12+9=35$

The probability is defined as

$p=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}$

Probability of getting red ball = $\frac{14}{35}$

Probability of getting blue ball = $\frac{12}{35}$

Probability of getting yellow ball = $\frac{9}{35}$

It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.

The probability of both balls are blue is

$\frac{12}{35}\times \frac{12}{35}=\frac{144}{1225}$

The probability of getting first red and second yellow ball is

$\frac{14}{35}\times \frac{9}{35}=\frac{18}{175}$

The difference between the minimum data point and the maximum data point is called the range. This is a measure of spread.
Other measures of spread include the interquartile range/IQR, which helps eliminate outliers, the standard deviation, and the mean absolute deviation. Measures of central tendency include the mean, median & mode.
