A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the team. The rest of the team finished the job in 14 days. How many people left the team?

Let x be the number of people who left the team.
(Hint: Focus on the work left after several workers left. )

Answer:

a. 37.5

b. 75%

c. 64%

d. 43.75%

Step-by-step explanation:

a. [tex]\frac{3}{8}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

8x = 3(100)

8x = 300

x = 37.5

37.5%

b. [tex]\frac{9}{12}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

12x = 9(100)

12x = 900

x = 75

75%

c. [tex]\frac{16}{25}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

25x = 16(100)

25x = 1600

x = 64

64%

d. [tex]\frac{42}{96}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

96x = 42(100)

96x = 4200

x = 43.75

43.75%

Answer:

57.926%

Step-by-step explanation:

Calculation for the probability that it is less than

16.4 inches long

Using this formula

z = (X - μ) / σ

Where,

X represent Date=16.4

μ represent Mean=16.2

σ represent Standard deviation=0.9 inches

Let plug in the formula

z = (16.4 - 16.2) /0.9 inches

z=0.2/0.9 inches

z = 0.2

Using Z-score table to find the area of 0.2

z=0.57926*100

z=57.926%

Therefore the probability that it is less than

16.4 inches long is 57.926%

Answer:

Yes, y = 7x(4x) is linear.

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1. Therefore, this equation is linear.

Answer:

-8

Step-by-step explanation:

The formula for slope is [ y2-y1/x2-x1 ].

1-9/7-6

-8/1

-8

Best of Luck!

Answer: The slope is equal to -8

Step-by-step explanation:

Since we know all of the points we can put it into the equation y2-y1 divided by x2-x1

So we input the numbers into the equation

1-9= -8

7-6= 1

-8/1 comes out to  -8

Answer:

The new cost is $73.95

The discount was $13. 05

Step-by-step explanation:

Turn the % into a decimal so it would be 0.15.

Then multiply it to the total, 87 x 0.15 = 13. 05

so the discount subtracted $13.05 off of the original price.

87 - 13. 05 = 73.95

Answer: The proportion of all AAII subscribers who are bullish on the stock market is 0.4094

Step-by-step explanation:

 Given the data in the question;

The total number of American Association of Individual Investors in stock market are;

409 + 299 + 291 = 999

The proportion of all AAII subscribers who are bullish on the stock market will be:

Market = 409 / 999

= 0.4094

Therefore, The proportion of all AAII subscribers who are bullish on the stock market is 0.4094

Answer:

Step-by-step explanation:

To determine the length of silver colored ribbon that Pete will need to put around a circular logo, we need to calculate the circumference of the logo.

The circumference of a circle can be found using the formula C = πd, where C represents the circumference and d represents the diameter of the circle. However, we are not given the diameter of the logo, so we cannot determine the exact length of the ribbon needed.

Assuming Pete knows the diameter or radius of the logo, he can calculate the circumference using the formula mentioned above. Once the circumference is determined, Pete will know how many inches of silver colored ribbon he will need. It is important to ensure that Pete has a little extra ribbon in case of any measurement errors or mistakes during the ribbon placement.

Answer:

23°

Step-by-step explanation:

Let the missing angle be x

Reference angle = missing angle = x

Opposite side to x = 14

Hypotenuse = 36

Applying trigonometric ratio, we have:

[tex] sin(x) = \frac{14}{36} [/tex]

[tex] x = sin^{-1}(\frac{14}{36}) [/tex]

x = 23° (to the nearest degree)

Answer:

  see attached

Step-by-step explanation:

Polynomial long division is done using the same methods as for numerical long division. Each quotient term is multiplied by the divisor, and that product subtracted from the dividend to get the new dividend. You are done when the degree of the dividend is less than the degree of the divisor.

As with numbers, 0 is put where a placeholder is needed. Here, that is needed for the (missing) x^2 term in the dividend.

As with numbers, the remainder is expressed as a fraction using the divisor as the denominator.

The full quotient is 4x^2 +2x +11/4 +37/(8x-4).

Welp,  I think this is it?

The proportion y = kx for k = 0 will be y = 0 and construct a horizontal line passing through the origin that is the x-axis.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given the direct proportion

y = kx

Now for k = 0

y = 0 so y = 0 is a horizontal line passing through the origin that is the x-axis.

In the graph below I have attached

Black line y = 4x ( k = 4)

Red line y = x ( k = 1)

Since k is decreasing the lines are becoming horizontal.

Hence "The proportion y = kx for k = 0 will be y = 0 and construct a horizontal line passing through the origin that is the x-axis".
