(3*8-3)/3

How do you solve this?

Answers

Answer:

7

Step-by-step explanation:

Equation: (3*8-3)/3

Step 1: (24-3)/3

Step 2: 21/3

Step 3: 7

Order of operations is used in this equation. You simplify the terms in the parentheses before the other terms in the equation. According to the order of operations (parentheses, exponents, multiplication, division, addition, and subtraction, you do the multiplication before the subtraction in the parentheses. Then you subtract your three from your multiplication result (twenty-four). This leaves you with 21. Finally, you divide twenty-one by three. This gets you seven.

Find 1 2/5 divided 2 1/3

Answers

Answer:

3/5

Step-by-step explanation:

7/5 / 7/3 = 3/5

Answer:

3/5

Step-by-step explanation:

First we make both fractions into improper fractions/top-heavy fractions:

1 2/5 = 7/5

2 1/3 = 7/3

Now we use the rule of KFC (keep flip change):

Keep the first fraction:

7/5

Change the sign to opposite:

÷ → ×

Flip the second fraction:

7/3 → 3/7

Now we multiply the fractions:

7/5× 3/7 = 7×3/5×7 =

21/35

Now we simplify this fraction to simplest terms:

Both the numerator and denominator can be divided by 7 :

3/5

So this is our final answer

in a certain urban area, the relationship between number of students, x in thousands, and the umber of schools, y , has an x-intercept of -4 and a y-intercept of 3. Write an equation for this relationship in standard form

Answers

Answer:

[tex]\sf -3x+4y=12[/tex]

Step-by-step explanation:

x-intercept is when y = 0   →   (-4, 0)

y-intercept is when x = 0   →   (0, 3)

[tex]\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{3-0}{0-(-4)}=\dfrac34[/tex]

Substitute one of the points and the found slope into the point-slope form of a linear equation:

[tex]\implies \sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac34(x-(-4))[/tex]

[tex]\implies \sf y=\dfrac34(x+4)[/tex]

[tex]\implies \sf 4y=3(x+4)[/tex]

[tex]\implies \sf 4y=3x+12[/tex]

[tex]\implies \sf -3x+4y=12[/tex]

c). What is the relationship between C and t linear?
d). If you graphed this relationship, is it sensible to join the points graphed with a straight line? Give reason with your answer.
e). For every increase of 1 hour for t, what is the change in C?
f). For an appointment with the lawyer, what is the fixed cost and variable cost?

Answers

Answer:

(a) The dependant veriable is the $120 per hour and the independant veriable is the $75 consultaion fee.
(b) The table of vaules for this would look like this, [tex]\frac{C}{T} \frac{75}{0} \frac{195}{1} \frac{315}{2} \frac{435}{3} \frac{555}{4}[/tex], where C = cost and T = time.
(c) The relationship between C and T is linear, beacause with the more hours you take the cost increases.
(d) Yes, it is sensible because the points would be in line due to the steady increase of the hourly rate.

(e) For every hour spent the cost increases 120 dollars.
(f) The fixed cost is 75 dollars for consultation and the veriable cost is 120 per hour.

The variance of the ages is

Answers

Considering the given discrete distribution, the variance of the ages is of 1.5844.

What is the mean and the variance of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.The variance is given the sum of the difference squared between each outcome and the mean, multiplied by it's respective probability.

In this problem, considering the distribution given in the table, the mean is given by:

[tex]E(x) = 13(0.09) + 14(0.22) + 15(0.25) + 16(0.28) + 17(0.15) + 18(0.02) = 15.39[/tex]

Hence, the variance is given as follows:

[tex]Var(x) = 0.09(13-15.39)^2 + 0.22(14-15.39)^2 + 0.25(15-15.39)^2 + 0.28(16-15.39)^2 + 0.15(17-15.39)^2 + 0.02(13-15.39)^2 = 1.5844[/tex]

Answers

The perimeter of the pentagon with apothem of 5cm is 28.87cm

How to calculate the perimeter of a pentagon

The sum of all the external sides of the pentagon is its perimeter.

First we need to calculate the half of one of its sides using the SOH CAH TOA

tan 30 = x/5

x = 5 tan 30

x = 2.89

One of the sides = 2(2.89) = 5.77 cm

Perimeter of th pentagon  = 5(5.77) = 28.87

Hence the perimeter of the pentagon with apothem of 5cm is 28.87cm
