The probability is 0.6 that if randomly choosen none of them are senior.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half .acc to our question-

What is one possible y coordinate
Answer:
Step-by-step explanation:
Answer x = 4 or x = -4.
Explanation: you can make what is called a 3-4-5 triangle. The base in this case is 3(from -2 to -5 there is 3 units), the hypotenuse is 5(length given in the question) therefore the height (also known as the y coordinate) is 4 or -4 if you flip the triangle.
A 50 foot ladder is set against the side of a house so that it reaches up 48 feet. If Shaniece grabs the ladder at its base and pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 38 ft.) Round to the nearest tenth of a foot.
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.
How to find the height of the ladder ?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
Therefore,
height of the ladder up the house = 43.9 ft

A Pringles chip can has a diameter of 8 cm and a height of 30 cm. Determine the volume of the cylindrical can.
The area of a circle is shown below.
A = πr²
The volume of the cylindrical Pringles chip can is 1508 cm³
Calculating the volume of a cylinderFrom the question, we are to determine the volume of cylindrical can
The volume of a cylinder is given by the formula
V = πr²h
Where V is the volume of the cylinder
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
Thus,
Volume of the cylindrical can = π× 4² × 30
Volume of the cylindrical can = π× 16 × 30
Volume of the cylindrical can = 480π cm³

The probability that the mean daily revenue for the next 30 days will exceed $7000 is 47.60%.
Define the term z score?The Z-score indicates the discrepancy between a given value and the standard deviation. The Z-score, also referred to as the median score, indicates how often standard deviations an actual data point deviates from the mean.The formula for the z score is-
z = (x - μ)/σ
In which,
z = standard scorex = observed value (= $7000)μ = mean ( = $7200)σ = standard deviation (=$1200)Put the value in formula
z = (7000 - 7200)/1200
z = - 0.16

P(x > $7000) = P(z > - 0.16)
See the p- value for obtained z from negative z score table.

A handicapped ramp is being constructed for the front entrance of First National Bank in Springfield. ADA guidelines requires a rise angle from the foot of the ramp (point furthest from the entrance) not to exceed 4.8 degrees. This means the vertical to horizontal ratio cannot exceed 1:12. If the handicapped ramp must start 15 feet away from the front entrance, contractors estimate the rise to be about 3 feet.
Part A: Explain thoroughly whether or not these ramp dimensions meet the ADA guidelines.
Part B: If the rise estimate does not meet ADA requirements, provide a measurement that would meet the guidelines.
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.
What is a slope?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 vertical change is of: 3 feet.The horizontal change is of: 15 feet.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:
3 feet vertical.39 feet horizontal.As the ratio would be of:
3/39 = 1/13 < 1/12.

How to find the equation of the graph line?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

2. To paint a house, a painting company charges a flat rate of $500 for supplies, plus
$50 for each hour of labor.
a. How much would the painting company charge to paint a house that needs
hours of labor? A house that needs 50 hours?
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.

PLEASE HELPPPPPP!!!!!!!!!!!
The distance between two cyclists after 45 minutes as described in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.
Speed, distance and time.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;
