A randomly chosen beagle has a 0.86508 probability of weighing more than 21.8 pounds.
How can probability be explained?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be represented as percentage with values between 0 and 1.
What does the term "z-score" mean?The relationship between a value and the mean of a group of values is quantified by a Z-score.
Adult male beagle weight is normally distributed, with a mean of 25.0 pounds and a standard deviation of 2.9 pounds.
Given values are:
Mean(μ) = 25 pounds
Standard deviation(σ) = 2.9 pounds
Sample mean(x') = 21.8
We need to calculate z-score:
z = (x' - μ)/σ
z = (21.8 - 25)/2.9
z = 1.25
P-value from Z-Table:
P(x>21.8) = 1 - P(x<21.8) = 0.86508
As a result, the probability of a randomly selected beagle weighing more than 21.8 pounds is 0.86508.

(0.75 -3.25) on a coordinate plane.
An ordered pair of point in Quadrant II is 8 units away from this point, the resulting point will be (-7.25, 4.25)
In this question, we need to find an ordered pair for the point in Quadrant II, that is 8 units away from the point Q(0.75 -3.25) on a coordinate plane.
If we have a coordinate point (x, y) in Quadrant ||, if the coordinate is 8 units away, the resulting coordinate will be expressed as (x - 8, y + 8)
Given the point Q(0.75, -3.25) on the coordinate the plane, if a point in Quadrant II is 8 units away from this point, the resulting point will be (0.75 - 8, -3.25 + 8) which is (-7.25, 4.25)

Someone pls help
hmmm first of all, let's keep in mind that any expression multiplied by 1 is always the same expression
[tex]12\cdot 1=12\qquad 13567\cdot 1=13567\qquad spaghetti\cdot 1=spaghetti[/tex]
and so on.
now, hmm 1 can be expressed as a rational, 1/1 = 1, but but but, we can really express it as
[tex]\cfrac{9999}{9999}\implies \cfrac{7857}{7357}\implies \cfrac{\sqrt[11]{1375}}{\sqrt[11]{1375}}\implies \cfrac{spaghetti}{spaghetti}\implies \cfrac{lettuce}{lettuce}\implies \text{\Huge 1}[/tex]
so let's do the so-called rationalizing of the denominator, we can also do it with the numerator btw, but we only need it for the denominator right now, by multiplying for 1 :), 1 is Da Bomb baby!!
[tex]\cfrac{5}{2\sqrt{5}}\cdot \text{\LARGE 1}\implies \cfrac{5}{2\sqrt{5}}\cdot \cfrac{\sqrt{5}}{\sqrt{5}}\implies \cfrac{5\sqrt{5}}{2\sqrt{5^2}}\implies \cfrac{5\sqrt{5}}{2(5)}\implies \cfrac{5\sqrt{5}}{10}\implies {\Large \begin{array}{llll} \cfrac{\sqrt{5}}{2} \end{array}}[/tex]
Find the x intercepts of the graph of the function.
g(x)=1/4(x-6)(x-3). Hint x intercepts happen when g(x)=0.
The x intercepts of the function given in the question will be equal to x = 6 and x = 3.
A function may be defined as an entity in which for one value of input there is only one value of output. The input value is the value of x variable, or the independent variable and the output value is the value of y variable or the dependent variable. For example, f(x) = y = x + 2, in this function for the value of input x = 1 the value of output is y = 3. The x intercept of a function may be defined as the point on the graph at which the line of function crosses the x axis. For finding the x intercept the y value or the value becomes zero. We are given the function g(x) = (1/4) (x - 6) (x - 3)
Now, g(x) = 0
(1/4) (x - 6) (x - 3) = 0
=> (x - 6) (x - 3) = 0
=> x = 6 and x = 3
Therefore, x intercepts are x = 6 and x = 3.

Describe how the change affects the volume of the prism or pyramid. Multiplying the height by 3/2.
Answer:
1512 cm²
Volume is also multiplied by [tex]\dfrac{3}{2}[/tex]
Step-by-step explanation:
The volume of a pyramid is given by the expression
[tex]V = \dfrac{1}{3} l\cdot w\cdot h[/tex]
where l = base length, w = base width and h = height
The volume of this pyramid
[tex]= \dfrac{18\cdot 12\cdot 14}{3} = 1008\; cm^3[/tex]
If we multiply the height by [tex]\dfrac{3}{2}[/tex] then new height
= [tex]14 \cdot \dfrac{3}{2} = 21 cm[/tex]
New Volume [tex]= \dfrac{18\cdot 12\cdot 21}{3} = 1512\; cm^3[/tex]
[tex]\dfrac{\text{NewVolume}}{\text{Old Volume}} = \dfrac{1512}{1008} = \dfrac{3}{2}[/tex]
So volume is also multiplied by 3/2
- 2(m - 2) = - 3(m = 5)
m = -19 is the solution to the equation -2(m - 2) = -3(m + 5).
What is the numerical value of m in the given equation?Given the data in the question;
-2(m - 2) = -3(m + 5)m = ?To determine the numerical value of m, remove the parenthesis and simplify.
-2(m - 2) = -3(m + 5)
Apply distributive property
-2(m - 2) = -3(m + 5)
m(-2) - 2(-2) = m(-3) + 5(-3)
-2m + 4 = -3m - 15
Now, collect like terms by bring all values containing variable m to the left and all constant to the right side of the equation.
-2m + 3m = -15 - 4
m = -15 - 4

R: {f(x) ∈ ℝ | f(x) ≥ –3}
R: {f(x) ∈ ℝ | f(x) ≤ –3}
Reason:
The smallest |x-5| can get is 0 since the result of an absolute value is never negative (because it represents distance).

John has $10,000 in debt with Discover, $4,000 in debt with Chase, $9,000 in debt with Citi Bank, and $3,000 in debt with Wells Fargo, giving him a total debt of $26,000. What percentage of John's total debt is with Discover?*
John holds 26 percent of the debt from discover bank in its total debt obligation.
What is a total debt?The Total debt represents the obligations being taken by a company in the form of debt and yet to be repaid by them to the lender.
Given that the Debt hold in discover bank is $10,000
Total debt: $26,000
Computation of ratio of debt in discover bank:
Debt proportion = Debt hold in discover bank / Total debt
Debt proportion = 10,000/ 26,000
Debt proportion = 26%
Therefore, John holds 26 percent of the debt from discover bank in its total debt obligation.

An agency charges $100 per person for a trip to a concert if 50 people travel in a group. But for each person above the 50, the amount charged for each traveler will be reduced by $3. If x represents the number of people above the 50, write the agency's revenue R as a function of x. (Assume that x is greater than zero.)
R(x)
The revenue of the the agency is given by the function
R(x) = 5000 - 50 x - 3x² .
A function is a relationship between an independent variable and a dependent variable which defines all points on a cartesian plane which satisfies the given condition.
The set of the independent variables is called a domain and the set of the dependent variable of the function is called a range.Each data in range is related to a particular data in the domain by the function.Now in the given Agency it is given that the charge of each tourist is $100 . Now for every tourist above 50 the charge is reduced by 3 dollars.
So for x people above 50 charge will be ( 100-3 x ) for all members.
The total revenue can be measured by the function
R(x) = ( 50 + x ) ( 100 - 3x )
or , R(x) = 5000 - 150 x + 100 x - 3x²
or, R(x) = 5000 - 50 x - 3x²
Hence the revenue function is given as : R(x) = 5000 - 50 x - 3x²

A transversal that crosses two parallel lines results in alternate exterior angles.
They form two pairs of alternate outside angles since they are situated "outside" the two parallel lines but on different sides of the transversal (four total angles).When a third line, a transversal, separates two lines, the expression "alternating exterior angles" is frequently used. The alternate exterior angles theorem states that pairs of alternate exterior angles are congruent if k and l are parallel.

We can formulate;
4x + y = 18 .... (i)
And, For second condition;
'3 compact disks and 4 thumb drives have a total capacity of 22 gigabytes.'
We can formulate;
4x + 3y = 22 .... (ii)
Solve the equation (i) and (ii) we get;
Subtract (ii) by equation (i) we get;
2y = 4
y = 2

You have a rectangular prism whose cross section is a square with side length
3 cm. You need to know its length, but you do not have a ruler. Luckily, you have a calibrated container of water nearby. The container has marks that measure cubic centimeters of liquid. It appears to have 70 cubic centimeters of water in it, but when you submerge the prism into the water, the water level rises to the 115-cubic-centimeter mark. Determine how long your prism is.
Answer:
side length = 5cm
Step-by-step explanation:
The volume of the prism is:
V = l × w × h
But we only know the width and height which are both 3cm. See image.
We put it in the calibrated container (container with markings on it) We find out the volume is 45. Because 115 - 70 is 45.
Divide to find the missing length. See image.
Vol
= 3 × 3 × sidelength
V = 9s
45 = 9s
5 = s

a=3 and b=6 and c=5 what is ab+bc?
Answer:
you have the values of a, b and c
all you gotta do is just plug them in so
ab+bc is (3)(6)+(6)(5)
which equals 48.
Answer:
48
Step-by-step explanation:
since a=3, b=6 and c=5, you would replace the letters in ab+bc with their numbers, making it (3)(6)+(6)(5). then you would multiply 3 x 6 which would be 18, and 6 x 5, which would be 30, making your expression 18+30. finally you would add them together, making it 48.
