Using the normal distribution, it is found that 60.06% of the salespersons earn between $32,000 and $42,000.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 40000, \sigma = 5000[/tex]

The proportion of salespersons that earn between $32,000 and $42,000 is the p-value of Z when X = 42000 subtracted by the p-value of Z when X = 32000, hence:

X = 42000:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42000 - 40000}{5000}[/tex]

Z = 0.4

Z = 0.4 has a p-value of 0.6554.

X = 32000:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{32000 - 40000}{5000}[/tex]

Z = -1.6

Z = -1.6 has a p-value of 0.0548.

0.6554 - 0.0548 = 0.6006 = 60.06%.

60.06% of the salespersons earn between $32,000 and $42,000.

The patterns shown by the erosion data measurements is that Western Beach is losing sand while Dunes beach is gaining sand.

It should be noted that erosion simply means the washing away of the top soil.

In this case, the patterns shown by the erosion data measurements is that Western Beach is losing sand while Dunes beach is gaining sand.

The years when the beaches have approximately the same width will be between 11 and 12 years.

Assuming these rates remain constant, to get a better approximation of when the two beaches will have the same width, one can plot the data against time and draw a curve that goes through the data.

Answer:

102° is the value of x

Step-by-step explanation:

A = 78°

B = x

C = 78°

D = x

All angles of parallelogram = 360°

→ A + B + C + D = 360°

→ 78° + x + 78° + x = 360°

→ 156 °+ 2x = 360°

→ 2x = 360° - 156°

→ x = 204/2

→ [ x = 102° ]

Hence, the value of x is 102°.

Step-by-step explanation:

Don't make life difficult with decimals. First multiply both sides with 10 to get rid of decimals.

10 (3x^2 + 2.5x) = 10 (12.5)

30x^2+ 25x = 125 (now rearrange to write in quadratic form)

30x^2 + 25 x - 125 = 0 (now we know a = 30, b= 25, c = -125)

Inequalities with one variable are plotted on a number line, with the output representing the solution to the inequality. A number line is used to graph a linear inequality with only one variable. Two-dimensional graphs plot linear inequalities with two variables because the output gives the solution to both variables.

Answer:

x>3

Step-by-step explanation:

on a number line, an open circle indicates that the given value (3) isnt included and you would use < or >. a closed (filled in) means that the given value is included and u would use ≤ or ≥. the direction of the arrow (left of right) indicates if the values will be greater than or less than the value indicated by the circle (3). Here, the arrow is pointing right meaning that the values are getting larger until infinity starting at 3 (3 isnt included because of the open circle)

For a graph, put the bottom(x) with the teachers and the side(y) with the number of students. Maybe that kind of helps?  You can choose how you want to space out the numbers on the side

Step-by-step explanation:

a pie chart is a circle with differently sized pizza slices designating how many or how much in every category in relation to the whole (the full circle).

a full circle = 360°.

the listed teachers together have obviously 200 students.

that means 200 is the whole, and correlates to 360° (everything takes the whole circle).

20 students for Michelle means then 20 of 200 :

20/200 = 1/10 = 360/10 = 36°

38 students for Rose Grace.

38/200 = 19/100 = 19×360/100 = 0.19 × 360 = 68.4°

28 students for Melanie.

28/200 = 7/50 = 7×360/50 = 7×36/5 = 50.4°

36 students for Joy.

36/200 = 9/50 = 9×360/50 = 9×36/5 = 64.8°

42 students for Josephine.

42/200 = 21/100 = 21×360/100 = 21×36/10 = 75.6°

36 students for Daisy.

36/200 = 9/50 = 9×360/50 = 9×36/5 = 64.8°

you need to draw a circle with the sectors having the listed degrees. of course, you round to the nearest full degree.

if done right, these sectors fill the whole circle.

A function assigns the values. The list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).

A function assigns the value of each element of one set to the other specific element of another set.

The rate at which the candle burns down is 0.5 inches per hour. Now, if we substitute the value of the point (0,9) in the function of a line, and the rate as well, we will get,

y = mx +c

9 = -0.5(0) + c

c = 9

Now, the equation that can represent the height of the candle at any hour after it is lit will be,

y= -0.5x+9

substitute the value of x as 1, 2, 3, 4, 5, and 6 to get the value of y and form ordered pairs.

Hence, the list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).

The region r is enclosed by the curves y₁ = 4 - 4x² and y₂ = 0 is 16/3 or 5.333 square units.

When the two curves intersect then they bound the region is known as the area bounded by the curve.

The region r is enclosed by the curves y₁ = 4 - 4x² and y₂ = 0

The intersection points will be

The probability that the hens lay more than two eggs is 0.80

The probability that the hens lay more than two eggs is calculated using:

P(x > 2) = P(3) + P(4) + P(5) + P(6)

Using the data on the table, we have:

P(x > 2) = 0.12 +  0.30 + 0.2 +, 0.18.

Evaluate the sum

P(x > 2) = 0.80

3 ) 948 cubic meters = 948000 liters

Step-by-step explanation:

1 )

Conversion

1 centimeter = 0.01 meters

1 cubic centimeter

= 0.01 x 0.01 x 0.01

Answer:

3/4 shall be our slope.

Step-by-step explanation:

You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.

Your coordinates:

(-4,0) and (0,3)

You have to set up your formula:

3 is the y2 and 0 is the y1

3-0 for y so far.

Now, set up the x's

0 is our x2 more known as our second x

Then our x1 is -4

0 - (-4).

Our Formula:

3-0 / 0+4

**Notice the negatives canceled to a positive due to the rule.**

3/4 shall be our slope.

You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
