the average gas mileage of a certain model car is 30.0 miles per gallon. if the gas mileages are normally distributed with a standard deviation of 0.75 miles per gallon, find the probability that a car has a gas mileage of between 29.8 and 30.2 miles per gallon.
By using normal distribution, it is obtained that the probability that a car has a gas mileage of between 29.8 and 30.2 miles per gallon is 0.2128
What is normal distribution?
Normal distribution is a continuous type probability distribution whose probability density function is
[tex]\frac{1}{\sigma \sqrt{2\pi}}e^{-\frac{z^2}{2}[/tex]
where, z = [tex]\frac{x - \mu}{\sigma}[/tex]
[tex]\mu[/tex] is the mean and [tex]\sigma[/tex] is the standard deviation
For x = 29.8, z = [tex]\frac{29.8-30}{0.75}[/tex] = -0.27
For x = 30.2, z = [tex]\frac{30.2-30}{0.75}[/tex] = 0.27
so, P(29.8 < x < 30.2) = P(-0.27 < z < 0.27)
= 2 [tex]\times[/tex] P(z < 0.27)
= 2 [tex]\times[/tex] 0.1064
= 0.2128

A 100-unit-long line is split in half.
Half of the line is used to form one large circle.
The other half forms two identical smaller circles.
Which is larger?
The circle with radius=7.95 is larger when a 100-unit long line is split in half.
What is meant by circle?A circle is a shape produced by all points in a plane that are a certain distance from the center. It is the curve drawn by a point traveling in a plane so that its distance from a specified point remains constant. The radius is the distance between any two points on a circle and the center. Typically, the radius must be positive. A degenerate instance is a circle with radius r=0. Except when otherwise noted, this article is about circles in Euclidean geometry, specifically the Euclidean plane.
A circle, in instance, is a fundamental closed curve that divides the plane into two regions: interior and exterior.
The perimeter of larger circle is 50 units
Therefore, 2πr=50
Radius=7.95
The perimeter of smaller circle is 25 units
Therefore, 2πr=35

3. Calculer la mesure des angles ADC et ABC de la figure ci-dessous.
Answer:
∠ ADC = 113° , ∠ ABC = 85°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180° , then
∠ ADC + ∠ ACD + ∠ CAD = 180° , that is
∠ ADC + 39° + 28° = 180°
∠ ADC + 67° = 180° ( subtract 67° from both sides )
∠ ADC = 113°
---------------------------
DA is an angle bisector of ∠ BAC , then
∠ BAD = ∠ CAD = 28° , then ∠ BAC = 56° , then
∠ ABC + ∠ BAC + ∠ ACB = 180° , that is
∠ ABC + 56° + 39° = 180°
∠ ABC + 95° = 180° ( subtract 95° from both sides )
∠ ABC = 85°

Blake was a little concerned as he stood in the middle of the overcrowded elevator. The sign clearly stated that the total weight in the elevator had a maximum capacity of 2,500 pounds.
Write an inequality to show the weight limit for the elevator.
w ≤ 2,500
w ≥ 2,500
w < 2,500
w > 2,500
The inequality that shows the maximum weight capacity of the elevator is w≤ 2500
InequalityInequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign. The meaning of inequality is to say that two things are NOT equal. One of the things may be less than, greater than, less than or equal to, or greater than or equal to the other things.
To represent the weight limit for the elevator using inequality, we can write it out as
w = weightw ≤ 2500

a food marketing institute found that 32% of households spend more than $125 a week on groceries. assume the population proportion is 0.32 and a simple random sample of 145 households is selected from the population. what is the probability that the sample proportion of households spending more than $125 a week is less than 0.3?
Using the normal distribution, the probability that the sample proportion of households spending more than $125 a week is less than 0.3 is 30.29%.
Normal distribution refers to a continuous probability distribution wherein values lie in a symmetrical fashion mostly centered around the mean. In a normal distribution, the probability is calculated using the z-score of a measure X. A Z-score refers to a numerical measurement that defines a value's relationship to the mean (of a group of values).
In order to determine the probability of the sample proportion, the z-score of a measure X is determined.
z-score = (X - µ)/σ where µ is the mean and σ is the standard deviation.
The standard deviation σ = √(p(1-p)/n
From the given data:
n = no of random sample = 145
p = probability of success (household spending more than $125) = 0.32
Hence,
σ = √((0.32(1-0.32)/145) = 0.0387
Calculating the z-score when X = 0.3
z-score = (0.3 – 0.32)/0.0387 = -0.516
From the table, the probability of z = -0.516
P(X<z) = 0.30293 or 30.29%
The probability that the sample proportion of households spending more than $125 a week is less than 0.3 is 30.29%.
