For easy estimation, option A = nearest hundred,B = nearest ten, C = nearest hundred and D= nearest thousand.

3529 and 3689

3529 to the nearest hundred = 3500 and,

3689 to the nearest hundred = 3700

∴ Required sum = (3500+3700) = 7200

33 and 99

33 to the nearest ten = 30 and,

99 to the nearest ten = 90

∴ Required sum = (30+90) = 120

120777 × 523

Answer:

4.35

Step-by-step explanation:

The expected value can be defined as: [tex]\sum{x_i*p_i}[/tex] where x_i = the payout, and p_i = the probability of it occurring.

This gives us the expression: [tex](1 * 0.35) + (2 * 0.2) + (5 * 0.1) + (8 * 0.2) + (10 * 0.15) = 0.35 + 0.4 + 0.5 + 1.6 + 1.5 = 4.35[/tex]

So the expected payout is 4.35

In unitary method we will learn how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.

When we go to the market to buy any article, we ask the shopkeeper to tell the price of the article. This is called unit price. We calculate the price of number of articles, we want to buy, with the help of this unit price. Sometimes, we calculate unit price when the price of a multiple is given.

The solutions of the equations x - 5y = 0 and 15x + 10y = 17 at x and y is 1 and 1/5 respectively.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Given that:

The linear equations are:

x - 5y = 0

15x + 10y = 17

Solve the equations using elimination method:

Multiply equation 1 by 2

2(x - 5y) = 0

15x + 10y = 17

This can be solved as:

2x-10y = 0.....(1)

15x + 10y = 17....(2)

On subtracting equation 1 from 2

17x = 17

x = 1

The value of x is 1.

Substitute the value of x in equation (1)

2(1)-10y = 0

2=10y

y = 1/5

Thus, the value of x and y is 1 and 1/5 respectively.

Step-by-step explanation:

y = -6x^2 + 24x-100

solve for 'x'

y + 100 =   -6x^2 + 24x   = -6(x^2-4x)    complete the square for x

(y+100) /(-6 ) =    (x-2)^2 -4                     add 4 to both sides

(y+100)/(-6) +4   = (x-2)^2                       sqrt both sides

sqrt [  ( y+100)/(-6) + 4  ]  + 2 = x           change  x and y

Step-by-step explanation:

x_avg = (-2 + -1 + 1 + 2 + 3 + 4)/6 = 1.166666...

y-avg = (21 + 8.6 + 1 + 1 + 5 + 14.3) = 8.48333...

x      y       x-x_avg       y-y_avg          (x-x+avg)²           (x-x_avg)(y-y_avg)

sum of (x-x_avg)(y-y_avg) = -34.858

sum of (x+x_avg)² = 26.8333

slope = [(x-x_avg)(y-y_avg)/[(x+x_avg)²]

slope = -34.858/26.8333

slope = -1.29907

y = mx + b

y_avg = m(x_avg) + b

Answer:

Step-by-step explanation:

We can find the slope of the line by using the slope formula

m = ( y2-y1)/(x2-x1)  where ( x1,y1) and (x2,y1) are points on the line

Using the points  (0,-4) and  (2,0)

m = ( 0 - -4)/ ( 2 - 0)

   = ( 0+4)/( 2-0)

   = 4/2

Answer:

D

Step-by-step explanation:

A' represents everything outside of the circle A

B represents the space within circle B

A' intersection B is everything not in A that is in B.

The equation of the line is 3x + y = 1

The points are given as:

(5, −2) and (3, 4)

Start by calculating the slope (m)

m =(y2 - y1)/(x2 - x1)

This gives

m = (4 + 2)/(3 - 5)

Evaluate

m = -3

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -3(x + 2) +5

So, we have:

y = -3x - 6 + 5

Evaluate the like terms

y = -3x - 1

Rewrite as:

3x + y = 1

Hence, the equation of the line is 3x + y = 1

Step-by-step explanation:

Answer:

b = 21

Step-by-step explanation:

In general for these trig problems look for the angle whose measure you are given or need to find and for the sides you are given lengths or whose sides you need to find.

Given:

side AB = 10 cm

m<C = 25°

Find:

side AC

The angle of interest here is <C whose measure is 25°.

Now look at the given side and the side you are looking for with respect to angle C, the given angle.

For angle C, AC is the adjacent leg.

For angle C, AB is the opposite leg.

Which trig function relates the opposite leg to the adjacent leg?

It is the tangent, since, in general, tan X = opp/adj.

tan C = opp/adj

tan 25° = AB/AB

tan 25° = 10 cm/b

Solve for b.

b × tan 25° = 10 cm

b = 10 cm / tan 25°

Using your calculator, divide 10 by the tangent of 25°.

b = 21.44506...

Answer: b = 21

Answer:

[tex]b = \bf 21 \space\ cm[/tex]

Step-by-step explanation:

• To solve for a side using SOH CAH TOA, first check the angle whose measure is given.

In this case, we know ∠ C is 25°.

• Next we have to figure out the relationships between the given angle and two sides: one side whose length we know, and the other whose length we have to find.

In this case, the side opposite to ∠ C is known to be 10 cm, and the side adjacent to ∠ C is AC, whose length, b, we have to find.

• The trigonometric ratio that relates the adjacent and opposite sides of an angle is tan, where:

[tex]\boxed{tan \theta = \frac{opposite}{adjacent} }[/tex] .

We can use this relationship to calculate the value of b:

⇒ [tex]tan (25 \textdegree) = \frac{10}{b}[/tex]

Solving for b:

⇒ [tex]b \cdot tan (25 \textdegree) = 10[/tex]

⇒ [tex]b = \frac{10}{tan (25 \textdegree)}[/tex]

⇒ [tex]b = 21.45[/tex]

⇒ [tex]b \approx \bf 21 \space\ cm[/tex]  (rounded to the nearest whole number)

The first step in the construction of a line perpendicular to line AB and passing through an external point m is:

a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB

To construct a perpendicular line, a compass and a scale are used.

Consider a line AB and an external point M.

Step 1:

Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.

Step 2:

Name the two intersecting points on line AB as X and Y.

Draw the arcs from these two points to the opposite side of point M with the same compass width.

Step 3:

Name the intersecting point of two arcs as N.

Draw a line connecting the two points M and N using scale.

Step 4:

Using a protractor, measure the angle of the line MN with the line AB.

The angle must show 90°.

Thus, the line MN perpendicular to line AB and passing through an external point M is constructed.
