A shop owner can buy two televisions and three DVD players for $1750 or four televisions and one DVD players for $1250. Find the cost of one of each

Answers

Answer 1

Answer:

Television = $200 and DVD player = $450

Step-by-step explanation:

→ Make 2 equations

Televisions = t and DVD players = d

2t + 3d = 1750

4t + d = 1250

→ Multiply the bottom equation by 3 to make the same variable of d

2t + 3d = 1750

12t + 3d = 3750

→ Minus the two equations to isolate the d variable

-10t = -2000

→ Divide both sides by -10 to find the cost of one television

t = 200

→ Substitute t = 200 back into 4t + d = 1250

800 + d = 1250

→ Minus 800 from both sides to isolate d

d = 450

What is Place Value?

In math, every digit in a number has a place value. Place value can be defined as the value represented by a digit in a number based on its position in the number. For example, the place value of 7 in 3,743 is 7 hundred or 700. However, the place value of 7 in 7,432 is 7 thousand or 7,000.

Given here: The number 56

To convert it to 506 we must add 506-56=450

∴ we must 45×10 to 56 to convert it to 506

Hence, 45 tens must be added to get 506

4 - 3|x + 1| < -17

Answers

Answer: x > 6, x < -8

Subtract 4 from both sides.

−3∣x+1∣<−17−4

Then simplify -17 - 4 to -21.

−3∣x+1∣<−21

Divide both sides by −3.

|x + 1| > -21/-3

Two negatives make a positive.

|x + 1| > 21/3

simplify 21/3 to 7

Break down the problem into these 2 equations.

x + 1 > 7

-(x + 1) > 7

Solve the 1st equation: x + 1 > 7

x > 6

Solve the 2nd equation: -(x + 1) > 7

x < -8

last collect all solutions

x > 6, x < -8

A random sample of 12 chemists from Washington stats shows an average salary of $39,420 with a standard deviation of $1659. A random sample of 26 chemists from New Mexico has an average salary of $30,215 with a standard deviation of $4116. Find the 98% confidence interval of the difference of means.

Answers

Answer:

Step-by-step explanation:

Given that :

μ1 = 39420 ; σ1 = 1659 ; s1 = 12

μ2 = 30215 ; σ2 = 4116 ; s2 = 26

df1 = 12 - 1 = 11

df2 = 26 - 1 = 25

98 % confidence interval of the difference in sample means :

Pooled Variance :

S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)

((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75

Standard Error :

√(S²p/n1) + (S²p/n2)

√(12605874.75/12) + (12605874.75/26)

= 1239.0847

Art: A rectangle is graphed on a coordinate plane. The horizontal x-axis and vertical y-axis are solid. The vertex labeled as A lies on begin ordered pair 0 comma 0 end ordered pair. The vertex labeled as B lies on begin ordered pair a comma 0 end ordered pair. The vertex labeled as D lies on begin ordered pair 0 comma b end ordered pair. The vertex C is unlabeled. Diagonals A C and B D are drawn by dotted lines.

The coordinates of rectangle ABCD are A(0, 0), B(a, 0), C( , ), and D(0, b). The length of AC⎯⎯⎯⎯⎯ is equal to . The length of BD⎯⎯⎯⎯⎯ is equal to . The diagonals of the rectangle have the same length. Therefore, AC⎯⎯⎯⎯⎯ is congruent to BD⎯⎯⎯⎯⎯.

Answers

Step-by-step explanation:

Given coordinates of the rectangle ABCD:

A(0, 0), B(a, 0), C(x, y), D(0, b)

Lets first find coordinates of C

We can see that A and B are on same line horizontally, so C and D will be on the parallel line

The distance AB and CD are equal also distance AD and BC are equal, therefore

AB = a - 0 = a, CD = aAD = b - 0 = b, BC = b

So the coordinates of C are:

x = a, y = b

Now the diagonals:

AC = √(a-0)² + (b-0)² = √a²+b²BD =√(0-a)² + (b -0)² = √a² + b²

Since AC = BD, we can state they are congruent

Using the given sets of points, identify slope (m), y-intercept (b), and write the equation. (0, 4) and (-1, -1)

Answers

Answer:

y = 5x + 4

Step-by-step explanation:

Its a given that the y intercept is 4 because on that point x = 0

B= 4

now you solve for your slope using y - y' / x - x'

when you plug in the numbers you get -1 - 4 / -1 - 0 which simplfies to -5 / -1 which simplifies just to 5, so we know the slope is = 5

now we just plug In and the base equation is y = mx + b.
