The probability that the mean daily revenue for the next 30 days will exceed $7000 is 47.60%.

The formula for the z score is-

z = (x - μ)/σ

In which,

Put the value in formula

z = (7000 - 7200)/1200

z = - 0.16

Thus,

P(x > $7000) = P(z >  - 0.16)

See the p- value for obtained z from negative z score table.

P(x > $7000) = 0.4760

Thus, the probability that the mean daily revenue for the next 30 days will exceed $7000 is 47.60%.

The distance between two cyclists after 45 minutes as described in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.

It follows from the task content that the distance between the two cyclists after 45 minutes is to be determined from the given parameters.

Given; the speed of the first cyclist is; 12 miles per hour, while the speed of the second cyclist is b miles per hour greater than that of the first.

The speed of the second cyclist is therefore; (b + 12).

On this note, since the distance covered by each cyclist is given by;

Distance = Speed × Time where, Time = 45 minutes = 0.75 hours.

Therefore, the total distance between the two cyclists can be determined from the expression as follows;

7 + 0.75 (12) + 0.75 (b + 12).

Therefore, the distance between the two cyclists as required in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.

When one lists their ages and their heights as ordered pairs (age, height), the statement that is true is D. It is both a relation and a function.

A relation between two sets is a collection of ordered pairs that each contain one object from the other set. If the ordered pair (x,y) is in the relation and the object x is from the first set and the object y is from the second set, the objects are said to be related. A relation is a type of function.

A function is a relation that states that there should be only one output for each input (or) we can say that a function is a special type of relation (a set of ordered pairs) that follows a rule, i.e., every X-value should be associated with only one y-value.

It should be noted that based on the information, only one value can be attributed to each person. Therefore, the correct option is D.

The measurement of the distance from the tip of the slice of pizza to the crust is the radius.

The diameter of the pizza is 12 inches and the circumference is 37.7 inches

A slice of pizza is cut from the middle of the pizza to the crust. It is therefore cut from the middle of the pizza (circle) to the edge of the pizza (circle).

This is the radius because the radius is the straight - line distance from the edge of the middle of a circle to the edge.

If the radius is 6 inches, the diameter is:

= radius x 2

= 6 x 2

= 12 inches

The circumference is:

= π x diameter

= 22/7 x 12

The distance up the house the ladder will reach after pulling it 10 feet further from the base of the house is 43.9 ft.

The ladder is set against the side of the house so that it reaches up 48 feet.  Shaniece grabs the ladder at its base and pulls it 10 feet farther from the house.

The height of the ladder on the house can be computed as follows:

The situation form two right angle triangle.

The initial distance of the base of the ladder from the house can be calculated as follows;

using Pythagoras's theorem,

b² = 50² - 48²

b = √2500 - 2304

b = √196

b = 14 ft.

Therefore, the initial distance of the ladder from the base of the house is 14 feet.

Let's find the height of the ladder on the house after pulling it 10 ft further.

using Pythagoras's theorem,

b² = 50² - 24²

b = √2500 - 576

b = √1924

b = 43.8634243989

b = 43.9 ft

Answer:

Step-by-step explanation:

You want the value of p(x)=5x^3+6x^2+4x for x=-5 and x=15.

Writing a polynomial in Horner form can simplify evaluation.

  p(x) = ((5x +6)x +4)x

  p(-5) = ((5(-5) +6)(-5) +4)(-5) = (-19(-5) +4)(-5) = 99(-5) = -495

  p(15) = ((5(15) +6)(15) +4)(15) = (81(15) +4)(15) = 1219(15) = 18285

a) These ramp dimensions do not meet the ADA guidelines.

b) A measurement that would meet the guidelines is the ramp starting 39 feet away, with a height of 3 meters.

The slope of a situation is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

For the ramp in this problem, we have that the vertical change and the horizontal change are given as follows:

The ratio between the vertical change to the horizontal change is of:

3/15 = 1/5.

Which is greater than 1/12, hence the ramp does not meet the ADA guidelines.

If the horizontal change was 13 times the vertical change, it would meet the ratio, hence a possible measurement is of:

The function represented by the graph has an equation of f(x) = |x - 3| + 5

From the question, we have the following graph that can be used in our computation:

The graph is an absolute value graph

As a general rule, an absolute value is expressed as

y = |x - h| + k

In this case, the vertex is

Vertex = (h, k)

As a general rule, the vertex of a function is the minimum point on the graph

On the given graph, the minimum point is (3, 5)

This means that

(h, k) = (3, 5)

Substitute the values (h, k) = (3, 5) in the equation y = |x - h| + k

So, we have the following representation

y = |x - 3| + 5

Rewrite the equation as a function

f(x) = |x - 3| + 5

Hence, the equation of the graph represented by the figure is f(x) = |x - 3| + 5

Using mathematical operations, Betsie should buy the 250 envelopes from Letters2go Shop at a total cost of £319.

To determine the total cost, we first determine the unit cost of an envelope at each shop.

The unit cost is multiplied by the number of envelopes required less the cost of free envelopes at Value World.

The mathematical operations used include division and multiplication.

Answer:

If a house need 50 hours to paint, it will cost $3000

Step-by-step explanation:
--- According to the problem, $500 is the cost for supplies, which means that for every house, that cost will be there. In other words, this payment never changes no matter the house. So far you pay $500

--- Now, the problem says that you pay $50 for each hour of labor. Since the house need 50 hours, we will multiply 50 (the cost) by 50 (the hours) = 2500.

--- Now we put the payments together. 500 + 2500 = 3000. So it will cost $3000 to paint a house that need 50 hours.

Option A is the correct answer.

A Square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Old mirror.

Side = 9 cm

Area = 9 x 9 = 81 cm²

New mirror.

Side = 8 cm

Area = 64 cm²

Side = 7 cm

Area = 7 x 7 = 49 cm²

Side = 6 cm

Area = 6 x 6 = 36 cm²

64 cm² is closer to 81 cm².

r is the radius

and h is the height

From the given information,

Diameter = 8 cm

But,

Radius = Diameter / 2

Therefore,  

r = 8 / 2 = 4cm

h = 30 cm
