Step-by-step explanation:

Answer:

1. $82,500

2. 169 : 110

Step-by-step explanation:

The computation is shown below:

Given that

1. Ratio between two computers is 3:2

And the first computer cost is $55,000

Let us assume the price of the second computer be x.

As we know that

Product of extremes = Product of mean.

2 : 3 :: 55000 : x .

Now cross mutiplication is to be done

2x = $55,000 × 3

x = $1,650,000 ÷ 2

= $82,500

2. Now if the price of the 2nd computer rised by $2,000

So the new cost would be

= $82,500 + $2,000

= $84,500

Now the ratio would be

= $55,000 :  $84,500

= 169: 110

Answer:

[tex]y = 7(3^x)[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (0,7)[/tex]

[tex](x_2,y_2) = (4,567)[/tex]

Required

Determine the formula

An exponential function is of the form:

[tex]y = ab^x[/tex]

For point [tex](x_1,y_1) = (0,7)[/tex]

[tex]7 = ab^0[/tex]

[tex]7 = a*1[/tex]

[tex]7 = a[/tex]

[tex]a = 7[/tex]

For point [tex](x_2,y_2) = (4,567)[/tex]

[tex]567 = ab^4[/tex]

Substitute 7 for a

[tex]567 = 7*b^4[/tex]

Divide both sides by 7

[tex]81 = b^4[/tex]

Take 4th root of both sides

[tex]\sqrt[4]{81} =\sqrt[4]{b^4}[/tex]

[tex]\sqrt[4]{81} =b[/tex]

[tex]b = \sqrt[4]{81}[/tex]

[tex]b = 3[/tex]

Substitute 7 for a and 3 for b in [tex]y = ab^x[/tex]

[tex]y = 7 * 3^x[/tex]

[tex]y = 7(3^x)[/tex]

Answer:

Option (D)

Step-by-step explanation:

By applying sine rule in the triangle shown,

Since, [tex]\text{sin}\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

By this rule,

[tex]\text{sinx}=\frac{\text{5000}}{8000}[/tex]

x = [tex]\text{sin}^{-1}(\frac{5}{8})[/tex]

x = [tex]\text{sin}^{-1}(0.625)[/tex]

x = 38.682°

  ≈ 38.7°

Therefore, Option (D) is the correct option.

Answer:

12

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle

3x + 4 + 2x + 1 = 6x - 7 add like terms

5x + 5 = 6x - 7

5 + 7 = 6x - 5x

12 = x

Answer:

y=x+0.625

Step-by-step explanation:

Since, x represents the number of hour kiran read,

According to the question,

The number of hours Andre read = 5/8 more than the number of hour kiran read

= 5/8 more than x

= x + 5/8 of x

Answer:

125

Answer:

1. Three things influence the margin of error in a confidence interval estimate of a population mean: sample size, variability in the population, and confidence level. For each of these quantities separately, explain briefly what happens to the margin of error as that quantity increases.

Answer: As sample size increases, the margin of error decreases. As the variability in the population increases, the margin of error increases. As the confidence level increases, the margin of error increases. Incidentally, population variability is not something we can usually control, but more meticulous collection of data can reduce the variability in our measurements. The third of these—the relationship between confidence level and margin of error seems contradictory to many students because they are confusing accuracy (confidence level) and precision (margin of error). If you want to be surer of hitting a target with a spotlight, then you make your spotlight bigger.

Answer:

the three things influence the margin of error in a confidence interval estimate of a population mean - sample size variability in the population and confident level as the variability in the population increases the margin of error increases. as the cofidence level increases, the margin of error increases.

Answer:

Step-by-step explanation:

-1.5(4-R)=12 divide both sides by -1.5

4-R=12/-1.5 calculate

4-R= -8 subtract 4 from both sides

-R=-8-4 calculate

-R=-12 multiply by -1

R=12

Answer:

The equation of a line that passes through the points (-2, 8) and (1,−1) in the fully reduced form will be:

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:8\right),\:\left(x_2,\:y_2\right)=\left(1,\:-1\right)[/tex]

[tex]m=\frac{-1-8}{1-\left(-2\right)}[/tex]

[tex]m=-3[/tex]

As the equation of a line in point-slope form is given by:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -3 and the point (-2, 8)

[tex]y-8=-3\left(x-\left(-2\right)\right)[/tex]

[tex]y-8=-3\left(x+2\right)[/tex]

[tex]y-8+8=-3\left(x+2\right)+8[/tex]

[tex]y=-3x+2[/tex]

Therefore, the equation of a line that passes through the points (-2, 8) and (1,−1) in the fully reduced form will be:

Answer:

Slope is 8 here

Y= mx +c

And c= 8

Y = - 2x + 8

Answer: 42

Step-by-step explanation: 3 x 14

Explanation:

Each time x goes up by 1, y goes up by 18

slope = rise/run

slope = (change in y)/(change in x)

slope = 18/1

slope = 18

You can also use the slope formula to get the same answer. Let's say we picked the points (2,36) and (3,54). We then would get

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

m = (54-36)/(3-2)

m = 18/1

m = 18

We get the same result as before.

Since x represents the number of years and y is the number of inches, the slope of 18/1 indicates an increase of 18 inches per 1 year, or just 18 inches per year.

Answer:

The required value of x is 12 units.

Step-by-step explanation:  Given that the figure A is a scale image of figure B.

We are to find the value of x.

Since figure A is the scale image of figure B, so both the figures are similar to each other.

Also, the corresponding sides of the similar figures are proportional, so we get

Thus, the required value of x is 12 units.
