Answer:

Mean: 12 Mode: 15

Step-by-step explanation:

Mean: 6+15+15+13+14+12+9=84/7=12 The mean is all of the numbers added together and then divided by how many number there are

Mode: 6, 9, 12, 13, 14, 15, 15.  The mode is the number that appears most often.

The total amount received at the end of the month is given as follows:

Ghc 570.

The total amount is obtained applying the proportions in the context of the problem.

The salary is divided as follows:

The person had Ghc 9500 in sales, which is 9500 - 8500 = 1000 Ghc over 8500 Ghc, hence the total amount received is obtained as follows:

550 + 0.02 x 1000 = Ghc 570.

Answer:

The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.

Step-by-step explanation:

Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.

piecewise function defines the function graphed between y=2x+3 and y=-1/3x+3.

How to compare linear equations?

The comparison method, a procedure for solving systems of independent equations, starts by rewriting each equation with the same variable as the subject. Any of the variables may be chosen as the first variable to isolate. Each equation is now an isolated-subject equation, and equation where one variable is isolated.

Given:

y = 2x+3

y = -1/3x+3

The left portion of the blue curve is y = 2x+3 but it is only graphed when x < 0 (we could argue that  but I'll set that aside for the other portion).

The right portion is the line y = -1/3x + 3 and it's only graphed when

Both lines have y-intercept 3.

Answer and Step-by-step explanation:

To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:

7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8

So, Reuben used 5/8 yards more red fabric than yellow fabric.

The range is the best measure of variability for this data, and its value is 4.

The line plot displays the number of roses purchased per day at a grocery store, with the data values ranging from 0 to 4 (since there are no dots above 4).

The best measure of variability for this data is the range, which is the difference between the maximum and minimum values in the data set. In this case, the minimum value is 0 and the maximum value is 4, so the range is:

Range = Maximum value - Minimum value = 4 - 0 = 4

Therefore, the range is the best measure of variability for this data, and its value is 4.

The number of T-shirts and shorts did Dots sell in the month of April with the total sales of $570 are 60 and 30 respectively.

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Dots sells T-shirts ($5) and shorts ($9).

Let suppose the number of T-shirts sold is x and shorts sold is y. Dots sells T-shirts ($5) and shorts ($9) with total sales of $570. Thus,

\(5x+9y=570\)

Solve it further,

\(5x+9y=570\\9y=570-5x\\y=\dfrac{570-5x}{9}\)                  ....1

People bought 2 times as many T-shirts as shorts. Thus,

\(x=2y\)                          ....1

Put the value of y form equation in this equation as,

\(x=2\times\dfrac{570-5x}{9}\\9x=1140-10x\\10x+9x=1140\\x=\dfrac{1140}{19}\\x=60\)

Put this value of x in equation 2 as,

\(x=2\times y\\60=2\times y\\y=\dfrac{60}{2}\\y=30\)

The cricketer's average for the last 10 innings was 15.67 runs per innings (approx.).

The average for the last 10 innings, we need to follow these steps:

Calculate the total runs scored in the first 20 innings. Total runs scored = Average * Number of innings = 15 * 20 = 300

Calculate the total runs scored in the next 10 innings. Total runs scored = Average * Number of innings = 17 * 10 = 170

Calculate the total runs scored in all 30 innings. Total runs scored = 300 + 170 = 47

Calculate the average for all 30 innings. Average = Total runs scored / Number of innings = 470 / 30 = 15.6

Calculate the total runs scored in the last 10 innings. Total runs scored = Average * Number of innings = 15.67 * 10 = 156.7 (approx.)

Calculate the average for the last 10 innings. Average = Total runs scored / Number of innings = 156.7 / 10 = 15.67

A system of linear inequalities represented by the graph are;

Inequality 1: y ≤ 3x - 3

Inequality 2: y ≥ ¹/₂x - 3

Inequalities that use < or > symbols are usually plotted with a dashed line that shows us that the line is not included in the region. Meanwhile, Inequalities that use ≤ or ≥ symbols are normally plotted with a solid line that shows us that the line is included in the region.

The general formula of equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, the graph that rises to the right side in the first quadrant has;

Slope = (3 - 1)/(3 - 2)

Slope = 3

the y-intercept is at y = -3

Thus, equation is;

y ≤ 3x - 3

Thus, the graph that rises to the left side in the second quadrant has;

Slope = (1 - 0)/(2 - 0)

Slope = 1/2

the y-intercept is at y = 1

Thus, equation is;

The Scale Factor is 0.75, or 3/4

Scale factor is a ratio of two related lengths, areas, volumes, or other quantities. It is used to describe how a figure is enlarged or reduced in size. For example, when a figure is enlarged, the scale factor is greater than one, and when a figure is reduced, the scale factor is less than one. Scale factors can be used to calculate the lengths of sides and areas of figures when one side or area is known.


The Scale Factor is calculated by dividing the coordinates of point A' (9, 3) by the coordinates of point A (12, 4). Therefore, the Scale Factor is 0.75, or 3/4.

The amount to be deposited is $33582

An interest rate is the amount of interest due per period, as a proportion of the amount lent, deposited, or borrowed. The total interest on an amount lent or borrowed depends on the principal sum, the interest rate, the compounding frequency, and the length of time over which it is lent, deposited, or borrowed.

Given that, we need to find the deposited sum into the account in order to have 45000 in 6 years for a down payment on a​ house,

Formula to be used =

A = P(1+r)ⁿ

A = the Final Investment Value  

P = the Principal amount of money to be invested  

r = the rate of interest in decimal

n = Number of Time Periods  

45000 = P(1+0.05)⁶

45000 = P(1.05)⁶

Answer:

Step-by-step explanation:

n = nickels

d = dimes

q = quarters

1)  n + d + q = 39

n+d = q - 3

Translate to:  2)   n + d - q = -3

.05n + .1d + .25q = 6.7   amount of each coin times the number of coins must add to 6.7

Multiply both sides by 20...

3)  1n + 2d + 5q = 134

Combine 1) & 2)

n + d + q = 39

n + d  - q = -3

Add together

2n + 2d = 36

Divide by 2:

4)  n + d = 18

Combine 1) and 3)

n + d + q = 39         Multiply by -5 =>  -5n -5d -5q = -195

n + 2d + 5q = 134                              n + 2d + 5q = 134

Add together->                                 5)   -4n - 3d  = -61

Combine 4) and 5)

  n + d = 18   Multiply by 4 =>  4n + 4d = 72

-4n - 3d = 61                          -4n - 3d = -61

Add:                                               d = 11

11 dimes...

Plug that into 4)

n + 11 = 18

n = 18-11 = 7 nickels.

Plug that into 1.

n + d + q = 39

7 + 11 + q = 39

18 + q = 39

q = 39-18 = 21 quarters

21 quarters, 7 nickels, and 11 dimes.

21(.25) + 7(.05) + 11(.1) = 5.25 + .35 + 1.1 = 5.6 + 1.1 = 6.7   Check.

0.9412 = 94.12% probability that none of the gauges fails

Step-by-step explanation:

For each gauge, there are only two possible outcomes. Either it fails, or it does not. The probability of a gauge failing is independent of other gauges. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

3 gouges, each with a 0.02 probability of failing.

This means that \(n = 3, p = 0.02\)

What is the probability that none of the gauges fails?

This is P(X = 0).

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{3,0}.(0.02)^{0}.(0.98)^{3} = 0.9412\)

0.9412 = 94.12% probability that none of the gauges fails
