D. The probability that a randomly selected giraffe will be shorter than 18.5 feet tall is given as follows: 0.7340 = 73.40%.

E. The probability that a randomly selected giraffe will be between 19 and 19.9 ft tall is given as follows: 0.0968 = 9.68%.

F. The 75th percentile for the height of giraffes is given as follows: 18.54 ft.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 18, \sigma = 0.8[/tex]

The probability that a randomly selected giraffe will be shorter than 18.5 feet tall is the p-value of Z when X = 18.5, hence:

Z = (18.5 - 18)/0.8

Z = 0.625

Z = 0.625 has a p-value of 0.7340.

The probability that a randomly selected giraffe will be between 19 and 19.9 ft tall is the p-value of Z when X = 19.9 subtracted by the p-value of Z when X = 19, hence:

Z = (19.9 - 18)/0.8

Z = 2.375

Z = 2.375 has a p-value of 0.9912.

Z = (19 - 18)/0.8

Z = 1.25

Z = 1.25 has a p-value of 0.8944.

Hence:

0.9912 - 0.8944 = 0.0968 = 9.68%.

The 75th percentile is X when Z = 0.675, hence:

0.675 = (X - 18)/0.8

X - 18 = 0.8 x 0.675

X = 18.54 ft.

By solving equations we get to know that your cousin bought 356 shares of BP and 1448 shares of Exxon.

Initial investment:

x shares of BP at $90.75 per share + y shares of Exxon at $87.25 per share = $97,918.25

Sale of shares:

x shares of BP at $82.75 per share + y shares of Exxon at $61.25 per share = $74,090.25

We now have two equations with two variables, which we can solve using either substitution or elimination

0.875x($90.75) + 0.875y($87.25) = $85,648.23

x($82.75) + y($61.25) = $74,090.25

0.875x($90.75) - x($82.75) = $11,558.98 - 0.875y($87.25) + y($61.25)

0.875x($8) = $11,558.98 - 0.875y($26)

7x = $11,558.98 - $22.75y

We can then substitute this expression for "x" into either of the original equations to solve for "y".

(7($11,558.98 - $22.75y))/$8 + y($87.25) = $97,918.25

$81,763.03 - $19.9375y + $87.25y = $97,918.25

$7.0125y = $10,155.22

y = 1448

Step-by-step explanation:

We have the system of equations:

1/x + 2/y = 1 -----(1)

-1/x + 8/y = -6 -----(2)

We can use the substitutions u = 1/x and v = 1/y to rewrite the equations in terms of u and v. Substituting, we get:

u + 2v = 1 -----(3)

-u + 8v = -6 -----(4)

Now we can solve the system in terms of u and v. Adding equations (3) and (4) gives:

2v = -5

Dividing both sides by 2, we get:

v = -5/2

Substituting this value of v into equation (3) gives:

u + 2(-5/2) = 1

Simplifying:

u - 5 = 1

u = 6

Therefore, we have u = 6 and v = -5/2.

To find the solution set in terms of x and y, we substitute back:

u = 1/x, so 6 = 1/x, and x = 1/6

v = 1/y, so -5/2 = 1/y, and y = -2/5

Therefore, the solution set to the original system is x = 1/6 and y = -2/5.

The factorized form of the equation is 3((3x + 10)(9x - 10) ) = 0.

The given quadratic equation is simplified as follows;

81x² + 180x - 200 = 100

Collect similar terms together;

81x² + 180x = 100 + 200

81x² + 180x = 300

81x² + 180x - 300 = 0

Factorize the equation by using a common factor;

3(27x² + 60x - 100) = 0

Factorize further as follows;

3(27x² + 90x - 30x - 100) = 0

3( 9x (3x + 10) - 10(3x  + 10) )= 0

The cost of shelving Nathaniel’s DVD collection is 15.75×27=$425.25.

We are given that;

Dimensions =7.5in, 5.3in, 0.6in

To find the cost of shelving Nathaniel’s DVD collection, we need to find how many shelves he needs and multiply that by the price of each shelf. To find how many shelves he needs, we need to find how many DVDs can fit on one shelf and divide that by the total number of DVDs.

Since the shelves are 31.5 inches wide and the DVDs are 5.3 inches wide, we can fit 5.331.5​≈5.94 DVDs on one shelf. We round this down to 5 DVDs per shelf because we cannot fit a partial DVD on a shelf.

Since Nathaniel has 132 DVDs in his collection, he needs 5132​=26.4 shelves. We round this up to 27 shelves because we cannot use a partial shelf.

Therefore, by algebra the answer will be 15.75×27=$425.25.

The Cost of the blue paint that would cover the shaded area = $0.495

The Cost of the white paint that would cover the triangular shapes = $0.6678

Recall the following formulas:

Area of a circle = πr²

Area of a triangle = 1/2 * base * height.

Area the blue paint will cover = 2(1/2 * base * height) = 2(1/2 * 1.5 * 1)

Cost of the blue paint = 1.5 * 0.33 = $0.495

Area the blue paint will cover = πr² - area of the two triangles

The total cost of the art supplies without the coupon is:

2 paint brushes x $10.50 per brush = $21.00

1 dozen colored pencils x $7.88 per dozen = $7.88

1 sketch book x $16.12 per book = $16.12

Total cost without coupon = $21.00 + $7.88 + $16.12 = $45.00

With the $15.00 off coupon, the total cost becomes:

$45.00 - $15.00 = $30.00

The amount saved by using the coupon is:

$45.00 - $30.00 = $15.00

The percentage saved can be calculated as:

Percentage saved = (Amount saved / Total cost without coupon) x 100%

Percentage saved = ($15.00 / $45.00) x 100%

Percentage saved = 33.33%

We can solve this problem using the conservation of momentum and the law of conservation of energy. Here's how:

Let v be the velocity of the 105 kg player just before the tackle. Then the velocity of the 156 kg player just before the tackle is -6 m/s, since he is running south. After the tackle, the two players move at a velocity of 3 m/s north, so we have:

Total momentum before = Total momentum after

(105 kg)(v) + (156 kg)(-6 m/s) = (105 kg + 156 kg)(3 m/s)

Simplifying and solving for v, we get:

v = (105 kg + 156 kg)(3 m/s) + (156 kg)(6 m/s) / 105 kg

v = 2.85 m/s

Therefore, the velocity of the 105 kg player just before the tackle was 2.85 m/s north.

After 0.50 hours, the cyclist's new elevation is h = 1.8 km.

Since the cyclist is riding downhill, we can use the formula h = h0 - Vt sin θ to calculate her new elevation. In this formula, h0 represents her initial elevation, V her speed, t her time, and θ her angle of descent. We are given h0 = 1.9 km, V = 25 km/hr, t = 0.50 hours, and θ = 2°.

h = 1.9 km - (25 km/hr)(0.50 hours)(sin 2°)

h = 1.9 km - (25 km/hr)(0.50 hours)(0.03492)

h = 1.8282 km

Answer:

Let x be the length of one side of the first carpet in feet. Then, the area of the first carpet is x^2 square feet.

Let y be the length of one side of the second carpet in feet. Then, the area of the second carpet is y^2 square feet.

From the problem, we know that the sum of the areas of the two carpets is 720 square feet:

x^2 + y^2 = 720

We also know that the difference of the areas of the two carpets is 432 square feet:

x^2 - y^2 = 432

We can solve this system of equations by using the method of substitution. Solving for x^2 in the second equation, we get:

x^2 = y^2 + 432

Substituting this expression for x^2 into the first equation, we get:

y^2 + 432 + y^2 = 720

Simplifying and solving for y, we get:

2y^2 = 288

y^2 = 144

y = 12

Substituting this value of y into the equation x^2 + y^2 = 720 and solving for x, we get:

x^2 + 144 = 720

x^2 = 576

x = 24

Therefore, the dimensions of the first carpet are 24 feet by 24 feet, and the dimensions of the second carpet are 12 feet by 12 feet.
