Find the equation of this line.

The probability that x is greater than 75 from a normal distribution with a mean of 100 and a standard deviation of 10 is 0.9151.

The formula for calculating the probability that x is greater than 75 from a normal distribution with a mean of 100 and a standard deviation of 10 is P(x>75)=1-P(x<75). The probability can be calculated using the cumulative distribution function of the normal distribution. The cumulative distribution function of the normal distribution is given by

F(x)=1/2[1+erf((x-mean)/(standard deviation*sqrt(2))]

Where erf is the error function defined by erf(x)=2/sqrt(pi)*∫x^0 e^-t^2 dt

Therefore, the probability that x is greater than 75 is

P(x>75)=1-1/2[1+erf((75-100)/(10*sqrt(2))]

=1-1/2[1+erf(-1.25)]

=1-1/2[1-0.1151]

=0.9151

The probability that x is greater than 75 from a normal distribution with a mean of 100 and a standard deviation of 10 is 0.9151.

a) The probability that all three family members are assigned to the same station is  1/27.

b) The probability that at most two family members are assigned to the same station is 11/27.

c) The probability that every family member is assigned to a different station is 2/9.

For (a), there is only one way for all three family members to be assigned to the same station, and there are 3 stations, so the probability is 1/3^3 = 1/27.

For (b), there are three ways for two family members to be assigned to the same station, either A and B, B and C, or A and C. The probability of two family members being assigned to the same station is (1/3)^2 (2/3). There are three ways for this to occur, so the probability is (3) (1/9) (2/3) = 2/3. There is also one way for all three family members to be assigned to the same station, so the probability is (1/3)^3 = 1/27. Adding these two probabilities gives 11/27.

For (c), there are 3! = 6 permutations for the family members to be assigned to different stations. Each family member can be assigned to any of the 3 stations, so the probability is (3!) (1/3)^3 = (6) (1/27) = 2/9.

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school can be calculated using the binomial probability formula. The binomial probability formula is [tex]P(x) = nCx * p^x * q^(n-x)[/tex]. For this problem, n = 6 (the number of calculators sent to the local high school), x = 1 (the number of defective calculators selected), p = 4/12 (the probability of selecting a defective calculator from the shipment of 12 calculators), and q = 8/12 (the probability of selecting a non-defective calculator from the shipment of 12 calculators). Plugging these values into the formula gives [tex]P(x) = 6C1 * 4/12^1 * 8/12^5[/tex], which simplifies to 0.29166. This means that the probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

Answer:

Kendall must have 5 dimes in her pocket.

Step-by-step explanation:

First, let's write down all the information that is given to us:

q = number of quarters   ["q, the number quarters"]

d = number of dimes     ["d, the number of dimes"]

q = 4     ["Kendall has 4 quarters in her pocket"]

25q + 10d = 150

Since the value of q is given to us, our equation now has one unknown variable, d, and we can solve for it.

25q + 10d =      150 [Plug in q]

25(4) + 10d =      150 [Simplify]

100 + 10d =      150 [Subtract 100 from both sides]

10d = 50     [Divide both sides by 10]

d = 5

So, since d=5, Kendall must have 5 dimes in her pocket.

If  the length of AB is the same as the length of DC, AC = 9, and

DE = 4, the length of DC is 6 units.

Since DE is parallel to AB and AC = 9, then we can use alternate interior angles to find the length of DC.

Using alternate interior angles, we have:

∠DAC = ∠EAB (Since they are alternate interior angles of two parallel lines)

And from the diagram, we have:

∠DAC = 90° (Since AC is perpendicular to DC)

∠EAB = 90° (Since AB and DE are parallel)

So, we have two right angles, ∠DAC = ∠EAB.

Let find the length of DC:

DC^2 = AC × DE

DC^2 = 9× 4

DC^2 = 36

DC = √36

DC = 6

Answer:

The list that has the angles of AABC in order from smallest to largest is: ZC, ZA, ZB

The measure of the angles of the triangle in order from smallest to largest is ∠C , ∠A , ∠B

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

And , In AABC, AB= 7, BC= 8, and AC=9

We can use the Law of Cosines to determine the size of each angle in AABC:

cos A = (b^2 + c^2 - a^2) / (2bc)

cos B = (a^2 + c^2 - b^2) / (2ac)

cos C = (a^2 + b^2 - c^2) / (2ab)

Plugging in the values of a = 9, b = 7, and c = 8, we get:

cos A = (7² + 8² - 9²) / (2 x 7 x 8) = 39/112

cos B = (9² + 8² - 7²) / (2 x 9 x 8) = 17/18

cos C = (9² + 7² - 8²) / (2 x 9 x 7) = 5/14

Taking the inverse cosine of each value gives:

A = cos^-1(39/112) ≈ 62.02°

B = cos^-1(17/18) ≈ 26.56°

C = cos^-1(5/14) ≈ 91.42°

And , the longest side in a triangle is always opposite the largest angle, and the shortest side is opposite the smallest angle and ∠C , ∠A , ∠B

Based on the provided lines and angles;

Let's discuss each problem we have:

Problem 2: Parallel lines m and n are cut by transversal l

Statement A: ∠1 = ∠5 is correct because both are corresponding angles and congruent.

Statement B: ∠2 = ∠4 is correct because both are vertical angles and congruent

Statement C: ∠2 = ∠7 is incorrect because ∠7 is the corresponding angle of ∠3 which is the supplementary angle of ∠2

Statement D: ∠3 and ∠6 form a linear pair is correct because both are consecutive interior angles and supplementary

Statement E: ∠4 and ∠5 are supplementary is correct because both are consecutive interior angles.

Problem 3: Parallel lines a and b are cut by transversal c and d

∠1 = 115°

∠8 = 105°

∠5 is adjacent and the supplementary angle of ∠8, then:

∠5 + ∠8 = 180°

∠5 + 105° = 180°

∠5 = 75°

∠11 is the alternate exterior angle of ∠5 and both are congruent, then:

∠11 = ∠5 = 75°

∠16 is the corresponding angle of ∠4 and congruent. ∠4 is the adjacent and supplementary of ∠1, then:

∠16 = ∠4

∠4 + ∠1 = 180°

∠16 + ∠1 = 180°

∠16 + 115° = 180°

∠16 = 65°

Timmy has been working at Monster Burger longer than Susie, which explains why he earns more money. Monster Burger employees are given a 50 cent raise each year, so Susie's salary will likely increase over time as she continues to work there.

Step-by-step explanation:

It is possible to determine how long Susie has been working at Monster Burger by using the information given. Since Timmy makes 720 dollars working 40 hours and Susie makes 600 dollars working the same hours, we can calculate their hourly wages:

Timmy's hourly wage: 720 / 40 = 18 dollars

Susie's hourly wage: 600 / 40 = 15 dollars

Since Monster Burger employees are given a 50 cent raise a year, this means that Susie's hourly wage has increased by 50 cents * x years, where x is the number of years Susie has been working there. Thus, we have:

15 + (0.50 * x) = 18

Solving for x, we get:

x = (18 - 15) / 0.50 = 6 years

Therefore, Susie has been working at Monster Burger for 6 years.
