Three more than twice a number is less than negative thirteen. Solve the inequality for the unknown number.
Answer:
Step-by-step explanation:
The number = x
Three more than the number = x + 3
twice the number = 2x
which means:
2x + 3 < -13
2x + 3 -3 < -13 -3 (subtract 3 from both sides)
2x < -16
2x/2 < -16/2 (divide 2 from both sides)
x < -8
A triangle has angles measuring 45°, 55°, and 80°. It is dilated by a scale factor of 2. What are the angle measures, in order from least to greatest, of the dilated image?
The angle measures, in order from least to greatest, of the dilated image 45°,55° and 80°.
A dilation is a function f from a metric space M into itself that satisfies the identity d=rd for all points x, y \in M, where d is the distance from x to y and r is some positive real number. In Euclidean space, such a dilation is a similarity of the space.
Euclidean space, In geometry, a two- or three-dimensional space in which the axioms and postulates of Euclidean geometry apply; also, a space in any finite number of dimensions, in which points are designated by coordinates (one for each dimension) and the distance between two points is given by a distance formula.
Dilations preserve angle measures, regardless of the scale factor. Therefore, the angle measures of the image will be the same of that of the pre-image, so our answer is still 45 °, 55 °, and 80 °.

There is a lower limit but no upper limit for a random variable that follows the _____ probability distribution.
There is a lower limit but no upper limit for a random variable that follows the exponential probability distribution.
We know that, an exponential distribution is a type of continuous distributions.
This probability distribution times the occurrence of events.
In exponential probability distribution, events happen continuously and independently at a constant average rate.
The continuous random variable, say X is said to have an exponential distribution, if it has the following probability density function:
[tex]f_X(x)=\left \{ {{\lambda e^{-\lambda x~~~x > 0}} \atop {0~~~~~~~x\leq 0}} \right.[/tex]
The exponential distribution is memoryless.
We know that, for exponential the lower limit is 0, but the upper limit is infinity, meaning there is no upper limit.
Therefore, There is a lower limit but no upper limit for a random variable that follows the exponential probability distribution.

What is Linear equation in one variable?A linear equation is a one-variable equation of a straight line. The variable's only power is 1. Linear equations in one variable with the form an x + b = 0 are solved utilizing basic algebraic operations.
Let x equal the number of letters obtained,
(x - 3) equal the number of bills obtained,
(x + 5) equal the number of advertisements received, and also
the number of magazines did receive is also given (x - 3).
The following equation can be derived:
x + (x - 3) + (x + 5) + (x - 3) = 3131
4x - 1 = 3131
4x = 3132
x = 784
Thus, number of bills received are-
(x - 3) = 784 - 3
number of bills received = 781.
Therefore, the number of bills obtained by brady family are 781.

If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:
-9 + 6 = -3
How to add using a number line?
When we have two values A and B and we want to add them using the number line, the first thing we need to do is select one of these two, and locate it on the number line.
Once we did that, the other number will tell us how many units we need to move to the left (if B is negative) or to the right (if B is positive).
In this case the two numbers are -9 and 6.
If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:
-9 + 6 = -3
We will get the exact same thing if we first step on the number 6 on the number line, and then move 9 units to the left, we will got -3.

Summarize the three conditions that must be checked before carrying out significance tests.
We introduced three conditions that should be met before we construct a confidence interval for an unknown population proportion: Random, Normal, and Independent.
What is random, normal and independent conditions?There are three crucial requirements that must be met in order to establish a confidence interval. These are Independent, Random, and Normal.
Any survey is carried out objectively.
It is required to assure randomness. An independent choice is equally likely to be made in a random sample. Similar to how the confidence interval is built, normal is used to confirm which phenomena are being employed or to correct the approach if necessary. In a similar vein, independent is crucial because it contains the facts to be analyzed. For the purpose of calculating the standard deviation, independent is used.
Therefore, it's crucial to consider the Random, Normal, and Independent criteria while building a confidence interval.

Step-by-step explanation:
Given - Dimensions of triangle and angles
of triangle
Find - Value of x
Solution - The value of x in the given triangle is 55°.
As per the given dimensions of the triangle, the triangle is isosceles. This states that the neighbouring angle will be x° as well.
Thus, the mathematical expression of all the angles of a given triangle will be -
x + x + 80 = 190
2x + 80 = 190
2x = 190 - 80

A tank truck fills the gas stations reservoir at the rate of 10 1/4 gallons per minute.if the reservoir was empty and it is now 41 gallons full how long has the tanker been filling the reservoir
The tanker has been filling the reservoir for 4 minutes given that it fills at a rate of 10 1/4 gallons per minute.
Rate refers to the relationship of two quantities of different units. Usually, it is a measure or quantity of something per unit time.
rate = amount / time
If a tank truck fills the gas station's reservoir at the rate of 10 1/4 gallons per minute, and if the reservoir is empty at the start and become 41 gallons full, we can determine how long the tanker has been filling the reservoir by dividing the final amount by the rate.
time = amount / rate
where amount = 41 gallons
rate = 10 1/4 gallons per minute
time = 41 gallons / 10 1/4 gallons per minute
time = 4 minutes

No. of matches they won,
→ y = 17 matches
Now the win percentage will be,
→ (y/x) × 100
→ (17/20) × 100

Ralph's grandmother was born in 1925. ralph was born in 1990. if both ralph and his grandmother took the intelligence quotient (iq) test, who would most likely get more items correct?
Ralph would most likely get more items correct than his Grandmother.
If both Ralph and his Grandmother took the Intelligence Quotient i.e., IQ test, then Ralph would most likely get more items correct than his Grandmother. This is due to Flynn Effect.
Flynn Effect refers to secular increase in population intelligence quotient observed throughout the 20th century. It demonstrates that the average of the IQ scores will change as varying generations have different thresholds for what intelligence is necessary.
Flynn Effect is documented by Flynn in a study on intelligence quotient. As Ralph's grandmother was born on 1925 and Ralph was born in 1990, so they have a generation gap of almost six decades. That is why Ralph will have a higher IQ than his grandmother.

Write the rational number 36/5 as a decimal
Answer:
36/5 as a decimal is 7.2
Step-by-step explanation:
In the fraction 36/5, 36 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 36/5 is same as "36 divided by 5" or "36 ÷ 5".
When we calculated 36 divided by 5, we found that 36/5 in decimal form is:
36 ÷ 5 = 7.2
Therefore, the decimal form of 36/5 is 7.2

Answer: u = 80° v = 25°
Step-by-step explanation:
(a) angles on a straight line = 180° - 130° = 50°
In isosceles triangle, both angles on each side is equal, so
180° - 50° - 50° = 80°
u = 80°
(b) u = (2v + 30°) because opposite angles of a parallelogram are equal.
u = 80°
80° = 2v + 30°
80 - 30 = 50
50° = 2v
25° = v
