Step-by-step explanation:

If 21 people study French and everyone studies some language, then the other 4 people must be Spanish only students. 25 - 21 =4

Since 13 people study Spanish,

13-4=9

9 people must study both Fr and Sp.

If 9 people study BOTH, then

21-9=12,

12 people must be the Fr only people.

The arch-looking, upsidedownU is intersect.

Fr intersect Sp are the StudyBOTH people.

P(Both) = Both/Total

= 9/25

If you need %, divide 9÷25 and times by 100. That's 36%

F' means Not French people, which is Spanish only people (thankfully there are no No-Language-studiers bc they would count too)

P(F')

= P (not Fr)

= P (Sp Only)

= 4/25 = 16%

Answer:

2n + 11

Step-by-step explanation:

You have twice an unknown number n, and you're going to want to have 11 more than that. So you will have 2 x n + 11 or 2n + 11.

The value of x is 4.8.

This theorem allows us to write:

AB/AC = BD/CD

AB = 8, AC = 10, and BD = x are known values. We may use the fact that the length of the opposing side is equal to the total of the lengths of the two segments that the angle bisector divides it into to determine CD. This is,

CD + AD = 12

Also known is that AD = 6. Therefore,

CD + 6 = 12 \sCD = 6

We can now enter the values necessary to solve for x:

x/6 = 8/10 10x = 48 x = 4.8 BD/CD = AB/AC

Hence, x has a value of 4.8.

The monthly payment for this difference would be $1,361.21. An Adjustable Rate Mortgage (ARM) is a type of mortgage in which the interest rate on the loan changes over time.

An Adjustable Rate Mortgage (ARM) payment is based on various factors such as the loan amount, interest rate, and the terms of the ARM. The interest rate is usually tied to a specific financial index, such as the U.S.

Here is the calculation format for the difference in payments between year 2 and year 3 for Bart and April's mortgage:

Total amount to be paid for the mortgage: $315,000

Rate of interest: 5.85% (Depreciating rate)

Time = 2 years:

a. Remaining amount to be paid after 2 years:

Principal × (1 - Rate/100)^time

= $315,000 × (1 - 5.85/100)²

= $315,000 × (1 - 0.0585)²

= $279,223.01

Time = 3 years:

a. Remaining amount to be paid after 3 years:

Principal × (1 - Rate/100)^time

= $315,000 × (1 - 5.85/100)³

= $315,000 × (1 - 0.0585)³

= $262,888.46

Difference in payments from year 2 to year 3:

= Remaining amount after 2 years - Remaining amount after 3 years

= $279,223.01 - $262,888.46

= $16,334.55

The monthly payment for this difference would be $1,361.21, which is calculated by dividing the difference in payments by 12:

$16334.546/12 = $1361.21

Based on these observations, option (d) 30 seems to be the most reasonable choice for a longer distance down the fairway.

To determine how far down the fairway the ball hits the ground, we need to consider the horizontal range of the golf ball. The range is the horizontal distance traveled by the ball before it hits the ground.

The range can be calculated using the formula:

Range = (Initial Velocity)² * sin(2 * Launch Angle) / g

Where:

Initial Velocity is the initial velocity of the golf ball (180 ft/sec).

Launch Angle is the angle at which the ball is hit off the tee.

g is the acceleration due to gravity (approximately 32.2 ft/sec²).

Since you haven't provided the launch angle for each club, we cannot determine the exact range for each one. However, we can make some general observations based on the given answer choices:

(a) 15: This option implies a lower launch angle, which would likely result in a shorter range.

(b) 20: Similar to option (a), a lower launch angle would generally result in a shorter range.

(c) 25: This option suggests a moderate launch angle, which could correspond to a reasonable range.

(d) 30: A higher launch angle typically leads to a longer range, so this option may result in a greater distance.

Based on these observations, option (d) 30 seems to be the most reasonable choice for a longer distance down the fairway.

However, without specific launch angles for each club, we cannot determine the exact answer.

Put the value in formula

z = (7000 - 7200)/1200

z = - 0.16

Thus,

P(x > $7000) = P(z >  - 0.16)

See the p- value for obtained z from negative z score table.

We want to find the slope of the line that connects points C' and D'. We will find that the slope is -3/7.

First, we start with the points:

Now we create points C' and D' by translating points C and D to the left by 6 units, this means that we need to subtract 6 in the x-value of each point, so we will have:

And we know that if a line passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:

\(a = \frac{y_2 - y_1}{x_2 - x_1}\)

Then the slope that connects points C' and D' is:

\(a = \frac{5 - 8}{2 - (-5)} = \frac{-3}{7}\)

Assuming that the stars cοme in οnly three cοlοrs (yellοw, red, and blue), and each cοlοr has an equal chance οf being selected, then the prοbability οf picking a star that is nοt yellοw is 2/3, and the prοbability οf picking a yellοw star is 1/3.

If we dο this experiment 16 times, we can use the binοmial prοbability fοrmula tο find the prοbability οf picking a nοn-yellοw star a certain number οf times:

\(\mathrm{P(x) = (n \ choose \ x) \times ^x \times (1-p)^{(n-x)}}\)

where n is the number οf trials, x is the number οf times we want tο pick a nοn-yellοw star, p is the prοbability οf picking a nοn-yellοw star (2/3), and (1-p) is the prοbability οf picking a yellοw star (1/3).

Using this fοrmula, we can calculate the prοbability οf picking a nοn-yellοw star exactly 1 time, exactly 2 times, and sο οn, up tο 16 times. We can then add up these prοbabilities tο get the οverall prοbability οf picking a nοn-yellοw star at least οnce in 16 trials.

To find the length of LJ in triangle JKL, we can use the trigonometric function cosine (cos) since we have the measures of two angles and one side length.

In triangle JKL, we have ∠L = 90°, ∠J = 25°, and KL = 26 feet. We want to find LJ. Using the cosine function:

cos(∠J) = LJ / KL

cos(25°) = LJ / 26

To solve for LJ, we can rearrange the equation:

LJ = KL * cos(∠J)

LJ = 26 * cos(25°)

Using a calculator to find the value of cos(25°) and multiplying it by 26, we get LJ ≈ 23.4 feet. Therefore, the length of LJ, to the nearest tenth of a foot, is approximately 23.4 feet.

Answer:

286.42

Step-by-step explanation:

So you have $400 at the start. You subtract $85.00 tax from your $400. You are left with $315. Then you subtract your social security tax of $15.20. You are left with $299.80. Lastly, subtract your Medicare tax of $13.38. You are left with $286.42.

Henry's net income is $186.42

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Henry's weekly paycheck shows a gross pay of $400.

There is a federal income tax deduction of $85.00

a social security tax deduction of $15.20,

and a Medicare deduction of $13.38.

So, Henry's Net income is

= 400 - (85+ 15.20+ 13.38)

A reflection about the x-axis followed by a reflection about the y-axis is equivalent to a rotation of 180 degrees about the point of intersection of the x-axis and the y-axis.

In order to find the measure of the acute or right angle formed by intersecting lines so that C can be mapped to C′ using two reflections, we need to apply the concept of rotations and reflections.

As given, a rotation (x,y) → (-x,-y) maps C to C′.

Now, if we reflect C′ across the x-axis, we get (-x,y) which is nothing but C reflected about the x-axis.

Again if we reflect C′ across the y-axis, we get (x,-y) which is nothing but C reflected about the y-axis.

Thus, to map C to C′ using two reflections, we reflect C about the x-axis and then about the y-axis.

Hence, the angle of rotation required to map C to C' is 180 degrees as one reflection is equivalent to a 180-degree rotation and hence, two reflections would be equivalent to a 360-degree rotation which is the same as no rotation at all (or a 0-degree rotation).

Therefore, the measure of the acute or right angle formed by intersecting lines so that C can be mapped to C′ using two reflections is 180 degrees.

Note: This can also be proven by the fact that reflections are equivalent to rotations about a line through the point of intersection of the two lines being reflected across.

If the demand for bananas at $2 per pound is 10 pounds, then the suppliers will supply 10 pounds of bananas.

The question is about determining the number of pounds of bananas suppliers will supply at a given price of $2 a pound.

To determine the number of pounds of bananas suppliers will supply, we need more information than just the price of bananas.

Supply is affected by many factors like cost of production, demand, and the price of substitutes.

Suppliers will supply bananas to the market until the price they get equals the cost of production plus a margin.

If the price is higher than the cost of production plus a margin, then they will continue to supply to maximize their profits.

In the given question, we don't have enough information about the cost of production, demand, and substitutes. Therefore, we cannot accurately predict the amount of pounds of bananas that will be supplied.

However, if we assume that the cost of production is constant and there are no substitutes, then the suppliers will supply bananas at a price of $2 per pound until the market reaches equilibrium.

At equilibrium, the quantity supplied equals the quantity demanded.
