The missing side length in the given right triangle is d) 23.6cm if the other two sides lengths are 14cm and 19cm respectively. So, correct option is d.
We know very well that if a triangle is a right angled it means that Pythagorean Theorem is applicable on it.
Pythagorean Theorem states that if a triangle is right angled then the sum of square of two sides which are originating from that angle which is 90 degree is equal to square of third side.
In other words,a²+b²=c² where a and b are two sides originating from 90 degree angle and c is the third side which is opposite of the 90 degree angle.
Now, we have a=14 and b=19cm,we need to find value of c.
So, putting the values, we get
=>14² + 19² =c²
=>c²=361+196
=>c² = 557
=>c=√557
=>c=23.6cm
Hence, missing side length is d)23.6cm

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.
Area to the right of 125 is 0.0475 and area to the left of 125 is 0.9525 .
What is area and area of shape ?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The area of a shape is the space enclosed within the perimeter or the boundary of the given shape.
Here, μ = 100, σ = 15 and x = 125. We need to compute P(X >= 125). The corresponding z-value is calculated using Central Limit Theorem.
z = (x - μ)/σ
z = (125 - 100)/15 = 1.67
z = 1.67
Therefore,
P(X >= 125) = P(z <= (125 - 100)/15)
= P(z >= 1.67)
= 1 - 0.9525
= 0.0475

describe the solution set for the system of equations that consists of the equation of the line shown and .y=1/2x-3
The correct statement according to the given equation is statement (D)"They have a single solution since they have various y-intercepts but the same slopes."
What is the equation?
The relationship between two terms on either side of an equal sign is easily demonstrated using a simple equation.
Additionally, one or more of the four arithmetic operations that simple equations do include addition, fundamental arithmetic, multiplication, and division.
The three possible forms of the equation system are point-slope form, standard form, and slope-intercept form.
So, given equations:
y = 1/2 * x - 3
y = - 1/2 * x - 3
As we are aware, a line's slope-intercept form is:
y = m x + c
Therefore, it is clear from equations 1 and 2 that:
m1 = 1/2 and c1 = -3
m2 = -1/2 and c2 = -3
Therefore, the correct statement according to the given equation is statement (D)"They have a single solution since they have various y-intercepts but the same slopes."

which functions have a zero at x equals 4? check all that apply. and (x )equals negative 2 x squared minus 18 x minus 40 b. c (x )equals 2 x squared minus 11 x plus 12 c. e (x )equals 3 x cubed plus x squared minus 48 x minus 16 d. a (x )equals x squared minus 3 x minus 28 e. b (x )equals x cubed minus 4 x squared minus x plus 4
The function that have a zero at x = 4 are
f(x) = 2x^2 - 11x + 12 f(x) = 3x^3 + x^2 - 48x - 16 f(x) = x^3 - 4x^2 - x + 4The first function is
f(x) = -2x^2 - 18x - 40
Substitute the value of x = 4
f(4) = -2(4)^2 - 18(4) - 40
= -2(16) - 72 - 40
= -32 - 72 - 40
= -144
The result is not zero
The second function is
f(x) = 2x^2 - 11x + 12
f(4) = 2(4)^2 - 11(4) +12
= 32 - 44 + 12
= 0
The result is zero
The third function is
f(x) = 3x^3 + x^2 - 48x - 16
f(4) = 3(4)^3 + 4^2 - 48(4) - 16
= 192 + 16 - 192 - 16
= 0
The result is zero
The fourth function is
f(x) = x^2 - 3x - 28
f(4) = 4^2 - 3(4) - 28
= 16 - 12 - 28
= -24
The fifth function is
f(x) = x^3 - 4x^2 - x + 4
f(4) = 4^3 - 4(4)^2 - 4 + 4
= 64 - 64 - 4 + 4
= 0
Therefore, the function f(x) = 2x^2 - 11x + 12, f(x) = 3x^3 + x^2 - 48x - 16 and f(x) = x^3 - 4x^2 - x + 4 have zero at x equals 4

Insurance Premium:
A premium is the amount an individual or business pays for an insurance policy. Premiums are paid for policies that cover health insurance, auto insurance, home insurance, and life insurance. When the premium is paid, it becomes income for the insurance company. It also constitutes liability, as the insurer must pay for claims arising from the policy. Failure to pay individual or corporate premiums may result in the cancellation of the policy.
The insurance company actuary is responsible for determining premium payments using statistics and calculations. Determine the likelihood of encountering an event or accident requiring insurance coverage. We will also be charged for any costs associated with the coverage.
Using the above factors to determine the premium, the actuary determines the price charged by the insurance company so that the amount the actuary receives is greater than the amount the company has to pay for the claim. increase.
Information gathered by actuaries is entered into tables called actuarial tables and passed on to insurance companies who set premium prices.

Step-by-step explanation:
x + y = 0 → (1)
5x + y = 4 ( subtract 5x from both sides )
y = 4 - 5x → (2)
substitute y = 4 - 5x into (1)
x + 4 - 5x = 0
4 - 4x = 0 ( subtract 4 from both sides )
- 4x = - 4 ( divide both sides by - 4 )
x = 1
substitute x = 1 into (1) and solve for y
1 + y = 0 ( subtract 1 from both sides )
y = - 1

A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6. Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°
Answer:
m∠5 + m∠6 =180°
m∠2 + m∠3 = m∠6
m∠2 + m∠3 + m∠5 = 180°
Step-by-step explanation:
m∠5 + m∠6 are linear pairs, so their sum has to be 180°.
m∠2 + m∠3 = m∠6 because of the exterior angle theorem, which states that the measure of an exterior angle is equal to the sum of the two opposite interior angles. (using this logic, m∠1 equals the sum of m∠5 and m∠3, and m∠4 equals the sum of m∠2 and m∠2).
m∠2 + m∠3 + m∠5 = 180° because the triangle sum property says that the sum of a triangle's interior angles will equal 180°.
Solve the following compound inequality.
9x + 6 > 132 and -7x + 19 < -128
The solution of the inequality 9x + 6 ≥ 132 and -7x + 19 < -128 is x ≥ 14 and x > 21.
How to solve compound inequality?Compound inequalities are a type of inequality that has two or more parts.
In other words, a compound inequality is an inequality that combines two simple inequalities.
Therefore, let's solve the compound inequality as follows:
9x + 6 ≥ 132 and -7x + 19 < -128
Let's solve them independently.
9x + 6 ≥ 132
subtract 6 from both sides of the inequality
9x + 6 ≥ 132
9x + 6 - 6 ≥ 132 - 6
9x ≥ 126
divide both sides by 9
x ≥ 126 / 9
x ≥ 14
-7x + 19 < -128
subtract 19 from both sides of the inequality
-7x + 19 - 19 < - 128 - 19
-7x < - 147
divide both sides by - 7
x > - 147 / -7
x > 21
Therefore, the solution is x > 21 and x ≥ 14

If the short on a clock is in 9 and the long hand is on 10 what time is it?
Answer: 9:50 AM/PM
Step-by-step explanation: Since the shorthand (hour) is on the 9, the hour is 9:00. The long hand (minutes) is on the 10, so it is 50. So, therefore we have 9:50. We don't know if it's am or pm, so we don't know if it's in the morning or the afternoon.
