The probability that the essay contains a grammar mistake or a spelling mistake is 11/32

To find the probability that an essay contains a grammar mistake or a spelling mistake, we need to add the probabilities of the essay containing only a grammar mistake, only a spelling mistake, and both a grammar and spelling mistake.

Let's first find the probability of an essay containing only a grammar mistake. From the given information, we know that 1/5 of the mistakes on the essays are grammar mistakes. So, the probability of an essay containing only a grammar mistake is

1/5 - 1/12 = 7/60

The subtraction of 1/12 is necessary because we don't want to count the mistakes that are both grammar and spelling mistakes twice.

Similarly, the probability of an essay containing only a spelling mistake is:

1/8 - 1/12 = 5/96

Again, we subtract 1/12 because we don't want to count the mistakes that are both grammar and spelling mistakes twice.

Finally, the probability of an essay containing both a grammar and spelling mistake is

1/12

Now, we can add these probabilities to find the probability that an essay contains a grammar mistake or a spelling mistake

7/60 + 5/96 + 1/12 = 11/32

The total actual area of the given logo is:  16.283 ft²

The given composite figure can be divided into a semi circle and a rectangle.

Formula for area of rectangle = length * width

Formula for area of semi circle = ¹/₂πr²

We are told that 1 inch on the printed copy actually represents 8 ft.

Thus:

¹/₂ inch = ¹/₂ * 8 = 4 ft

5/16 in = 5/16 * 8 = 2.5 ft

Thus:

Area of rectangle = 2.5 * 4 = 10 ft²

Area of semi circle = ¹/₂π * 2² = 6.283 ft²

The equation for determining the probability of two independent events occurring at the same time is,                       P(A and B) = P(A) * P(B). The probability that at least one of the two independent events occurs is,                                  P(A or B) = 1 - (P(not A) * P(not B)).

The equation for determining the probability of two independent events occurring at the same time is the product of their individual probabilities. For independent events A and B, the equation is:
P(A and B) = P(A) * P(B)

To find the probability that at least one of the two independent events occurs, you can use the complement rule. First, calculate the probability that neither event occurs (i.e., both events don't occur), and then subtract that from 1:
P(A or B) = 1 - P(not A and not B)

Since A and B are independent, the equation for the probability of neither event occurring is:
P(not A and not B) = P(not A) * P(not B)

So the final equation for the probability that at least one of the two independent events occurs is:
P(A or B) = 1 - (P(not A) * P(not B))

The solution is , f(x) = tan (x) the function is defined at 0≤x<90 is the domain of the function.

Given the function f(x) = tan (x)

From trigonometry identity, tan (x) = sin(x)/cos(x)

f(x) = sin(x)/cos(x)

Using the quotient rule to find the derivative of the function, we will have;

f'(x) = cos (x)cos (x) - sin (x)[-sin (x)]/ cos²x

f'(x) = cos²x - sin²x/ cos²x

Divide through by cos²x

f'(x) = cos²x/cos²x + sin²x/cos²x / cos²x/cos²x

f'(x) = 1 + sin²x/cos²x / 1

f'(x) = 1 + (sin²x/cos²x)

f'(x) = 1 + tan²x

From trig identity,  1 + tan²x = sec²x

Hence, f'(x) = sec²x

Hence the expression  f'(x)  in terms of the secant function is sec²x

f'(x) = 1/cos²x

For the function to be defined, it means that cos²x ≠ 0

cos²x ≠ 0

cos x ≠ 0

x ≠ cos⁻¹0

x ≠ 90⁰

Hence the value of x must not be equal to 90 for the function to be defined. x can be defined at when x = 0 since cos 0 = 1, the equation will  becomes f'(0) = 1/cos²0 = 1/1 = 1.

Hence the function is defined at 0≤x<90

The function represented by the graph in intercept form is:

f(x) = -0.00038(x + 5.8)(x + 5)(x + 2)(x - 1)(x - 4)

We have,

To write the function represented by the graph in intercept form, we need to find the x and y intercepts and write the function as a product of linear factors.

From the graph and the given points, we can see that the function has

4 x-intercepts at -5, -2, 1, and 4.

We can also see that the function has 3 turning points at (-3.8, 95), (-1.4, 35), and (2.5, 40).

To find the y-intercept, we can use the point (-5.8, -160), which the curve emerges from.

This means that the function can be written in the form:

f(x) = a(x + 5.8)(x + 5)(x + 2)(x - 1)(x - 4)

where a is a constant to be determined.

To find the value of a, we can use any of the given points that lie on the curve. Let's use the point (-3.8, 95):

95 = a(-3.8 + 5.8)(-3.8 + 5)(-3.8 + 2)(-3.8 - 1)(-3.8 - 4)

Simplifying and solving for a, we get:

a = -95/((5.8)(3)(0.8)(4.8)(7.8)) ≈ -0.00038

Therefore,

The function represented by the graph in intercept form is:

The formula for the volume of a right circular cylinder is:

V = πr²h

where "r" is the radius of the base, "h" is the height, and π is the mathematical constant pi (approximately 3.14).

Substituting the given values, we get:

V = π(5)²(6)

V = 150π cubic inches

Since we are asked to give the volume in cubic inches and not in terms of pi, we can approximate π as 3.14 to get:

V ≈ 150(3.14) ≈ 471

Therefore, the volume of the cylinder is approximately 471 cubic inches, which is closest to option (d) 150.

Step-by-step explanation:

We can use the ratios of similar triangles to solve this problem. Let's call the height of the tree "h". Then, we have two similar right triangles:

Kaylee's triangle: the height is 1.45 meters, the length of the shadow is 34.2 meters, and the angle between the height and the shadow is theta.

Tree's triangle: the height is h meters, the length of the shadow is 39.55 meters, and the angle between the height and the shadow is also theta.

Using these two triangles, we can set up the following proportion:

h / 39.55 = 1.45 / 34.2

Cross-multiplying, we get:

h * 34.2 = 39.55 * 1.45

Simplifying:

h = (39.55 * 1.45) / 34.2

h = 1.68176

So the height of the tree is approximately 1.68 meters (to the nearest hundredth of a meter).

If we randomly select a student who works part-time, the probability of that student also driving themselves to school is 1 or 100%.

To find the probability of randomly selecting a student who drives and works part-time, we need to use the formula for conditional probability. This formula states that the probability of event A given event B is equal to the probability of both events A and B occurring together, divided by the probability of event B.

In this case, event A is selecting a student who drives to school, and event B is selecting a student who works part-time. To find the probability of both events occurring together, we need to find the intersection of sets A and B, which is the group of students who both drive and work part-time. According to the Venn diagram, this group has a size of 3.

Therefore, the probability of selecting a student who drives and works part-time is:

P(A|B) = P(A and B) / P(B)

We can start by using the standard normal distribution to find the z-scores for the two heights:

z1 = (176 - 180) / 4 = -1

z2 = (180 - 180) / 4 = 0

Then, we can use a standard normal distribution table or a calculator to find the area under the curve between these two z-scores. From a table, we find that the area to the left of -1 is 0.1587 and the area to the left of 0 is 0.5. Therefore, the area between -1 and 0 is:

0.5 - 0.1587 = 0.3413

To find the percentage of the population, we can convert this decimal to a percentage by multiplying by 100:
