Step-by-step explanation:

The height of the hill is 520 ft

The height of the hill, h the length of the road, L and the ground form a right angled triangle with length of the road as the hypotenuse side and the height of the hill as the opposite side to the angle the road makes with the horizontal, Ф.

Now, from trigonometric ratios,

sinФ = h/L

Making h subject of the formula, we have

h = LsinФ

Since L = 2500 ft and Ф = 12°, thus

h = LsinФ

h = 2500 ft × sin12°

h = 2500 ft × 0.2079

h = 519.78 ft

h ≅ 520 ft to the nearest foot

So, the height of the hill is 520 ft

To determine the probability that the first 10 children tested are all okay, we need some additional information.

Specifically, we need the probability of a child being okay (referred to as "p" in this case) and whether the tests are independent or dependent. Assuming the tests are independent and the probability of a child being okay is denoted as "p", the probability of each child being okay is p. Since each child's test result is independent of the others, we can multiply the probabilities together.

Therefore, the probability that the first child is okay is p, the probability that the second child is okay is also p, and so on. Thus, the probability that the first 10 children tested are all okay is (p)(p)(p)...(p), ten times, which can be written as p^10. In summary, the probability that the first 10 children tested are all okay is p^10, assuming the tests are independent.

Answer:

3

Step-by-step explanation:

Hello!

It is asking for the answer is p is equal to 3 so we put 3 in for p

3 = 2n - 3

Add 3 to both sides

6 = 2n

Divide both sides by 2

3 = n

The answer is 3

Hope this helps!

Answer:

n = 3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

*3-(2*n-3)=0

Pull out like factors:

*6 - 2n  =   -2 • (n - 3)

Solve:

*-2   =  0 (This has no equation so we solve for the next side.)

*n-3 = 0 (Add 3 to both sides)

James has $37.67 now after all his expenses

James had $x, his brother had $y, and his sister had $z when the morning began.

By using algebra,

James's sibling had twice as much money as James.

Now, x =y/2..... (i)

James had $27 fewer dollars than his sister did.

So, x = z - 27 ........ (ii)

⇒  {From equation (1)}

⇒ y/2 = z -27

⇒ y = 2z - 54

⇒ 2z - y =54 ..........(3)

Now, James and his sister each received $12 from his brother.

James now has $(x + 12), his brother now has $(y -24), and his sister now has $(z + 12).

Given that James' sister has twice as much money as James' brother after payoff,

So, z+12/2 = y-24

⇒ z + 12 = 2y - 48

⇒ 2y - z = 50 ......... (4)

The result of resolving equations (3) and (4) is

3y = 54 + 100 = 154

⇒ y =  51.33.

The result of equation (3) is now z = 52.67.

And from equation (1), x = 51.3/2= 25.67

So, now, James has (25.67 + 12) = $37.67

Hence, James has $37.67 now after all his expenses

The z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

The z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

How to find the Z score

P(Z ≤ z) = 0.60

We can use a standard normal distribution table or a calculator to find that the z-score corresponding to a cumulative probability of 0.60 is approximately 0.25.

Therefore, the z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

For the second question:

We want to find the z-score such that the area under the standard normal distribution curve to the right of z is 0.30. In other words:

P(Z ≥ z) = 0.30

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52 (since we want the area to the right of z, we take the negative of the z-score).

Therefore, the z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

Answer:

Isosceles and Right

Step-by-step explanation:

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

Answer:

Isosceles and right

Step-by-step explanation:

We have a picture of triangle and are asked to name it, look at definitions below :

Isosceles - Geometrical figure with three sides and three angles

Right - Triangle where one angle is a right angle (90°)

Scalene - Triangle where all three sides have different lengths

Acute - Triangle where all three sides are less than 90°

If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.

Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.

To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.

Our answer left is Isosceles and Right.

The standard form of a linear equation is simply given Ax+By=C. In order to change an equation written in slope-intercept form (y=mx+b) to standard form, one should get the x and y on the same side of the equal sign and the constant on the other side.

One of the most popular ways to represent a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula can be used to determine the equation of a line.

Using a straight line's slope and the location of its y-axis intersection, the slope intercept equation can be used to determine the general equation of the line. Y = mx + b is the equation in slope intercept form.

Answer:

y = (x - 2)²

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, 0) , thus

y = a(x - 2)² + 0

To find a substitute the y- intercept (0, 4) into the equation

4 = a(- 2)² = 4a ( divide both sides by 4 )

a = 1

y = (x - 2)² ← equation of parabola in vertex form

Given

\(n= 60\) --- Number of rolls

\(p = \frac{2}{6}\) -- probability

Required

Determine the expected value

Expected value (E(x)) is calculated using:

\(E(x) = n * p\)

To find:

The size package of pasta which has the lowest unit price.

Solution:

We know that,

\(\text{Unit price}=\dfrac{\text{Total price}}{\text{Quantity}}\)

Now, the unit prices for all size package of pasta are

\(\text{Unit price}=\dfrac{0.99}{3}=0.33\)

\(\text{Unit price}=\dfrac{2.59}{8}=0.32375\)

\(\text{Unit price}=\dfrac{5.69}{16}=0.355625 \)

\(\text{Unit price}=\dfrac{11.89}{32}=0.3715625 \)

Here, the lowest unit price is 0.32375. So, 8oz size package of pasta has the lowest unit price.

Therefore, the correct option is B.

Solving a system of equations we can see that each pair of pants costs €82.94 and each coat costs €26.37

Let's define the variables:

x = cost of a pant

y = cost of a coat.

First, we know that:

3x + 2y = 245

And then there are discounts of 20% and 5%, and the cost of one of each is 100.75, then:

0.8x + 0.95y = 100.75

Then we have a system of equations:

3x + 2y = 245

0.8x + 0.95y = 100.75

We can isolate x on the second equation to get:

x = (100.75 - 0.96y)/0.8

x = 125.9 - 1.2y

Replace that in the other equation:

3*(125.9 - 1.2y) + 2y = 245

Solving for y:

3*125.9 - 3*1.2y + 2y = 245

y*(2 - 3*1.2) = 245 - 3*125.9

y = (245 - 3*125.9)/(2 - 3*1.2)

y = 82.94

Then the value of x is:

x = 125.9 - 1.2*82.94

x = 26.37

Using linear functions, it is found that option 2 will need the fewest amount of ticket sold.

A linear function is modeled by:

y = mx + b

In which:

For each option, we have that:

For option 1, the earnings with x ticket sales is given by:

y = 9500 + 0.05x.

With y = 13000, we find the amount of tickets that have to be sold to earn $13,000, hence:

13000 = 9500 + x

x = 3,500 tickets

For option 2, the earnings with x ticket sales is given by:

y = 8000 + 2x.

Hence:

13000 = 8000 + 2x

2x = 5000

x = 2,500

x = 2,500 tickets;

For option 3, the earnings with x ticket sales is given by:

y = 4500 + 3x.

13000 = 4500 + 3x

3x = 8500

x = 8500/3

x = 2,833 tickets.

Hence option 2 will need the fewest amount of ticket sold.

To compare the greater pay between a salary of $74,000 per year and an hourly rate of $40 for 80 hours every fortnight, we need to calculate the total earnings for each option.

Salary per year:

To calculate the total earnings for the salary option, we simply take the annual salary of $74,000.

Total earnings = $74,000 per year

Hourly rate:

To calculate the total earnings for the hourly rate option, we need to determine the total number of hours worked in a year. Since there are 26 fortnights in a year, and the lawyer works 80 hours per fortnight, the total number of hours worked in a year would be:

Total hours worked per year = 26 fortnights * 80 hours/fortnight = 2,080 hours

Now we can calculate the total earnings:

Total earnings = Hourly rate * Total hours worked per year

= $40/hour * 2,080 hours

= $83,200

Comparing the two options, we find that the greater pay is $83,200 from the hourly rate, which exceeds the $74,000 salary per year.
