The probability that a student who has skipped many classes has a GPA less than 2.0 is 0.5.

To calculate this probability, we can use the data from the table given. If a student has skipped many classes, they are in the "Many Skips" category. From the table, we can see that there are 200 students in the "Many Skips" category and 100 of them have a GPA of less than 2.0. Therefore, the probability of a student with many skips having a GPA less than 2.0 is given by:

P(GPA < 2.0 | Many Skips) = 100/200 = 0.5

This means that if we randomly select a student who has skipped many classes, there is a 50% chance that their GPA will be less than 2.0. This calculation provides insight into the relationship between attendance and GPA, and it suggests that skipping many classes is associated with a lower GPA.

If you start with 150 bacteria micrograms, the colony would have 1,343.61756 bacteria after 8 days.

We solve this problem using our understanding of the rules of calculating percentages. We have been given the condition that bacteria colonies increase by 73% after every 2 days.

So, starting with 150 bacteria,

after 2 days we'll be having

150+ (73% of 150) bacteria

i.e. 150 + (0.73×150)

=150 + 109.5

=259.5 bacteria

and after 4 days the no. will be,

259.5 + (0.73×259.5)

=259.5 + (189.435)

=448.935 bacteria

similarly after 6 days,

448.935 + (0.73×448.935)

=448.935 + (327.722)

=776.65755 bacteria

and finally after 8 days,

=776.65755 + (0.73×776.65755)

=776.65755 + 566.960012

The lateral surface area of the cylinder would be 157.78π.

        LSA = 2πr(h + r)                               .... Eq { 1 }

       dV = πr² dh

       For complete cylinder -

       ∫dV = πr² ∫dh

       V - 0 =  πr² [h - 0]

       V = πr²h                                           .... Eq { 2 }

Given is a cylinder with a height of 11.2 cm and radius of 4.9 cm.

We can write the lateral surface area of a cylinder as -

LSA = 2πr(h + r)  

LSA = 2π x 4.9 x (11.2 + 4.9)

LSA = 2π x 78.89

LSA = 157.78π

The cost per mile that Bill Novato had last year was $0.40.

As per the data given:

Last year, Bill Novato drove 38,986 miles.

Also he had the expenses as follows:

Gas: $7787. 25

Maintenance and miscellaneous: $318.80

Parking and tolls: $325.00

Tires: $300.00

Wash and wax: $75.00

insurance: $614.80

License, $74.90

Loan interest: $412.20

Depreciation: $5780.0

To find the cost per mile we just need to divide all the expenses Bill had on the car by the amount of miles he drove.

The total amount of expenses can be found by adding all the expenses together.

= 7787.25 + 318.8 + 325 + 300 + 75 + 614.8 + 74.9 + 412.2 + 5780

= 15687.95

The total expense of the car was $15687.95.

Dividing this value by the total amount of miles driven, we have:

Answer:

1/ At 10km, they will cost the same.

2/ It costs $199.50

Step-by-step explanation:

We know

Rental Company A, a rental car costs $55.50, and every kilometer costs $14.40.

Let Y represent the total cost, and x is the number of kilometers. We have the equation

y = 14.40x + 55.50

Rental Company B, a rental car costs $91.50, and every kilometer costs $10.80.

y = 10.80x + 91.50

How many kilometers will they cost the same?

14.40x + 55.50 = 10.80x + 91.50

3.6x = 36

x = 10 km

How much will it cost?

y = 14.40(10) + 55.50

y = 144 + 55.50

y = $199.50

The depth of the submarine after 9 minutes will be -102 feet.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression -210+ 12m represents a submarine that began at a depth of 210 feet below sea level and ascended at a rate of 12 feet per minute.

The depth of the submarine after 9 minutes will be calculated as:-

D =  -210+ 12m

Correct answer to the given question about Courtney's affordable car loan within her budget is option D. $27,425. 75.

To determine the maximum car loan that Courtney can afford, you need to calculate the total amount she will pay over 6 years and make sure it's less than the total amount she can afford to pay each month ($400) multiplied by the number of months (6 years x 12 months per year = 72 months).

First, calculate the total amount of interest she will pay over 6 years at 7.5% annual interest: $400 x 7.5% = $30

Next, calculate the monthly payment by dividing the annual interest amount by 12 months:$30 / 12 = $2.50

So, the monthly payment (not including the car loan amount) is $400 + $2.50 = $402.50.

Finally, you can calculate the maximum car loan amount by subtracting the monthly payment from the total amount she can afford to pay each month, and then dividing by the number of months:

$400 x 72 months = $28,800

$28,800 / $402.50 = 71.37

So, Courtney can afford a maximum car loan of $71,370.

The left Riemann sum approximation is 14.892

From the question, we have the following parameters that can be used in our computation:

The left Riemann sum can be expressed as:

Such that:

h = (b - a)/n

In this case, a = 2, b = 3.5, n = 3, and f(x) = 3^x

So, the left Riemann sum approximation is:

Approximation = (3.5-2)/3 * (f(2 + 1/3 * (3.5-2)) + f(2 + 2/3 * (3.5-2)) + f(2 + 3/3 * (3.5-2)))

y'(9) = -7/3.

Step-by-step explanation:

We start by differentiating the given equation with respect to x:

d/dx(√x + √y) = d/dx(10)

1/(2√x) + (1/2)y'(x)/√y = 0

Simplifying, we get:

y'(x) = -√y/√x

To find y'(9), we plug in x = 9 and y = y(9) = 49:

y'(9) = -√49/√9 = -7/3

Therefore, y'(9) = -7/3.

The value of P in this triangle is equal to 14.

In Mathematics, the basic proportionality theorem states that when any of the two (2) sides of a triangle is intersected by a straight line which is parallel to the third (3rd) side of the triangle, then, the two (2) sides that are intersected would be divided proportionally and in the same ratio.

By applying the basic proportionality theorem to the given triangle, we have the following:

24/p = 12/(21 - p)

By cross-multiplying, we have the following:

12p = 24(21 - p)

12p = 504 - 24p

36p = 504

p = 504/36

Answer:

141°

Step-by-step explanation:

In order to find the missing angle, we must first find the total sum of all the interior angles. To find this we use the following equation:

(n – 2) × 180°

Where n is equal to the number of sides

There are 7 sides therefore:

(7 – 2) × 180°

5 × 180°

900°

The sum of the total angles in the heptagon is 900°

We then must subtract all of the known angles

900 - 148 = 752

752 - 90 = 662

662 - 142 = 520

520 - 130 = 390

390 - 129 = 261

261 - 120 = 141

The missing angle is 141°

The possible dimensions of the rectangle will be 12 and 12√5.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that the area of the rectangle is 144√5. The dimensions of the rectangle can be calculated by factorizing the given area as below:-
