Answer: No.

Step-by-step explanation:

3 x 5 = 15,

but 10 x 5 = 50.

In order for the ratios to be equivalent, they would have to be written like this:

3/10 = 15/50

Therefore, it is not equivalent.

The proportion of slots who meet these specifications is 15.86%.

We are given that the width in inches of slots cut by a milling machine follows approximately the N(0.97,0.001) distribution.

Also, the specifications allow slot widths between 0.9698 and 0.9702

Let X = width in inches of slots cut by a milling machine

The z-score probability distribution for normal distribution is given by;

Z =  (X - μ) /σ  ~ N(0,1)

where, μ = population mean width = 0.97

           σ  = standard deviation = 0.001

The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

Now, Probability that the specifications allow slot widths between 0.9698 and 0.9702 is given by = P(0.9698 < X < 0.9702)

=  P(0.9698 < X < 0.9702)  = P(X < 0.9702) - P(X  0.9698)

P(X < 0.9702) = P  [(X - μ) /σ < [tex]\frac{0.9702 - 0.97}{0.001}[/tex]] = P (Z < 0.2) =

P(X ≤0.9698) = P [(X - μ) /σ ≤  [tex]\frac{0.9698 - 0.97}{0.001}[/tex] ] = P (Z ≤ -0.2) = 1-  P(Z < 0.2)

                                                                                  = 1 - 5793 = 0.4207

So, in the z table the P(Z  x) or P(Z < x) is given. So, the above probability is calculated by looking at the value of x = 0.2 in the z table which has an area of 0.5793.

Therefore,  P(0.9698 < X < 0.9702) = 0.5793 - 0.4207 = 0.1586

Hence, the proportion of slots who meet these specifications is 15.86%.

x = -14/9 is the solution to the equation ( 7x + 6 )/4 = ( 2x − 3 )/5 in a simplified improper fraction form.

Given the data in the question;

To solve for x, first we cross multiply

( 7x + 6 )/4 = ( 2x − 3 )/5

5( 7x + 6 ) = 4( 2x − 3 )

Remove the parenthesis using distributive property

7x×5 + 6×5 = 2x×4 − 3×4

35x + 30 = 8x - 12

Collect like terms by moving all terms containing x to the left and all constant terms to the right side of the equation.

35x - 8x = -12 - 30

27x = -12 - 30

27x = -42

Divide both sides by 27

27x/27 = -42/27

x = -42/27

x = -14/9

Therefore, the value of x in the given equation ( 7x + 6 )/4 = ( 2x − 3 )/5 is -14/9.

5N² is expressed as a product of prime factors in index form as  [tex]5^{5} * 3^{2} * x^{10}[/tex] .

In the expression of a number as the product of its prime factors, known as prime factor index form, each prime factor is only mentioned once, either as itself or, if necessary, to a required power.

Given:

N is a number that is expressed as a product of its prime factors in index form.

N = [tex]3x * 5x^{2} * x^{3}[/tex]

We have to express 5N² as a product of prime factors in index form.

5N² = 5([tex]3x * 5x^{2} * x^{3}[/tex])²

       = [tex]5 * 9x^{2} *5^{4} x^{2} *x^{6}[/tex]

If Stacy works alone, it will take her 11 hours 40 minutes to paint the doghouse.

If Diego works alone, it will take him 5 hours 40 minutes to paint the doghouse.

given data

Diego and Stacy can paint a doghouse in 5 hours

Diego works twice as fast as Stacy

Let x be the number of hours it would take Diego to paint the doghouse and y be the number

Putting the given information mathematically

Diego and Stacy can paint a doghouse in 5 hours

Diego works twice as fast as Stacy

x + y = 5hours

Since x = 2y

2y + y = 5

3y = 5

y = 5/3

y = 1 1/3

from x = 2y

x = 2 * 5/3

x = 10/3

x = 3 1/3

1/3 hours is a fraction of hours. we convert it to minutes by multiplying by 60

= 1/3 * 60

= 20 minutes

Therefore it will take Diego 3 hours 20 minutes and Stacy 1 hour 20 minutes for them to complete a 5 hours work

If Diego works alone

Diego alone = 5 hours + Stacy's hours * 1/2

since Diego is twice faster than Stacy then Stacy's time will be halved

Diego alone = 5 hours + 80 minutes * 1/2

Diego alone = 5 hours + 40 minutes

Diego alone = 5 hours 40 minutes

if Stacy works alone

Stacy alone =  5 hours + Diego's hours * 2

Stacy alone =  5 hours + 3 hours 20 minutes * 2

Stacy alone =  5 hours + 6 hours 40 minutes

Stacy alone = 11 hours 40 minutes

Answer:

D) 116

Step-by-step explanation:

Supplementary angles add up to 180°

 ∠CDE + ∠FDE = 180

3x + 10 + 6x + 8 = 180

3x + 6x + 10 + 8 = 180

Combine like terms,

              9x + 18 = 180

Subtract 18 from both sides,

                    9x  = 180 - 18

                    9x = 162

Divide both sides by 9

An equation that relates the total cost, y, and the number of lemons, x, is

y = 1.80x

where,

y =Total cost

x = number of lemon

When x = 4

y = 1.80x

y = 1.80(4)

y = 7.2

y = $7.2

When y = $4.20

y = 1.80x

4.20 = 1.80x

x = 4.20 / 1.80

x = 2 1/3

x = 2 1/3

When y = $9.00

y = 1.80x

9.00 = 1.80x

x = 9.00 / 1.80

x = 5

x = 5

When x = 18

y = 1.80x

y = 1.80 × 18

the angle C is the opposite angle to that of 85 degrees, therefore congruent, we subtract 85 x 2 ° from the sum of the angles (360 °, is a round angle) and find the sum of the other two angles, always opposite and increasing, divide by two and we have the value of the angle B

C = 85°

B = [360 - (85 * 2)] : 2

B = (360 - 170) : 2

B = 190 : 2

B = 95°

The value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

A straight line of the form  y = MX + c has its slope as 'm'

It is constant for a line. The more the slope is, the steeper the line is.

Sign convention takes bottom left to top right going line as positive sloped. And that line which goes from bottom right to top left is taken to have a negative slope. The horizontal line has 0 slopes and the vertical line has an infinite slope, as it is now at maximum steepness.

We have been given the equation cx+4y=12 which has a slope of  8.

Also cx+4y=12

4y = 12 - cx

y = 12/4 - cx/4

y = 3 - cx/4

Then we know that straight line of the form  y = mx + c

By comparing the formula;

y = 3 - cx/4

Slope = c/4 = 8

c/4 = 8

c = 8(4)

c = 32

Therefore, the value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

In this question, a triangle is dilated by a factor of 2 and then rotated clockwise.

We need to select the correct statement about the triangle's image and pre-image.

We know that rotation is a rigid transformation but dilation is not a rigid transformation.

Dilation does not preserve the size of the image.

Also, the image and pre-image are not congruent as the corresponding sides of triangle's image and pre-image are not equal.

Therefore, the correct statement about the triangle's image and pre-image is 'the image and pre-image are not congruent because one of the transformation is rigid transformation and the other is not.'

An irrational number that lies between the two given ones, 0.6333.... and 0.64 is:

√7 - 2.01 =0.63575...

Remember that an irrational number is a number that can't be written as the quotient between two integers.

Here we want to find two numbers between 0.6333 (where the 3 repeats infinitely) and 0.64

So we cold try to find a number like:

6.3349412490184...

Such that there is no pattern (because if there were a pattern, it would not be an irrational number).

An example of this can be, for example:

√7 = 2.64575...

This is an irrational number.

Now, if we subtract 2.01 from that we will get:

√7 - 2.01 = 2.64575... - 2.01 = 0.63575...

This is an irrational number and lies between the two given ones, then we conclude that √7 - 2.01 =0.63575... is a correct option.

For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.

First, solve for the z-score using the formula below.

z-score = (x – μ) / σ

where x = individual data value = 5 million

μ = mean = 4.56 million

σ = standard deviation = 720,000

z-score = (5 million - 4.56 million) / 720,000
