[tex]-5x+4 = 29 \iff -5x =29-4 \iff -5x = 25\\[/tex]

[tex]x = 25:(-5) \implies \bf x = -5[/tex]

Answer: X = 5

Step-by-step explanation: f(x) is 29, plus it in to f(x)=-5x+4

29=-5x+4

Subtract the 4 with itself and 29

-5x=25

Divide both numbers by -5, you dont want x to be a negative

X = 5

The equation of ellipse with foci (2, 4) and (2, -8) and co-vertices (10, -2) and (-6, -2) is ((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

To find the equation of the ellipse, we first need to determine the center of the ellipse. Since the foci are on the same vertical line, the center of the ellipse is at the midpoint of the segment connecting the foci.

The midpoint of the segment connecting the foci is:

((2+2)/2, (4-8)/2) = (2, -2)

So the center of the ellipse is (2, -2).

Next, we need to determine the lengths of the semi-major and semi-minor axes. The semi-major axis is half the distance between the co-vertices, which is:

a = (10 - (-6))/2 = 8

The semi-minor axis is half the distance between the foci, which is:

c = (4 - (-8))/2 = 6

Now we can use the standard form of the equation of an ellipse centered at (h,k):

((x - h)^2 / a^2) + ((y - k)^2 / b^2) = 1

where a is the length of the semi-major axis and b is the length of the semi-minor axis.

Plugging in the values we have:

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

Simplifying and rearranging:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

So the equation of the ellipse is:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

Step-by-step explanation:

1. In the calculation, only one pound of fish food is shared equally among one aquarium.

2. Each of the aquarium gets one pound of fish food

To solve the first part of the problem, we need to find the value of P when 1/2 ÷ 8 = P. By doing the calculation by hand, we get:

1/2 ÷ 8 = 0.0625. So, the  P = 0.0625.

In the second part of the problem, we know that 1 pound of fish is shared equally among a certain number of aquariums, and we need to find that number.

Since each aquarium gets 1 pound of fish food, and the total amount of fish food is 1 pound, we can set up an equation to solve for the number of aquariums:

1 pound of fish food / X number of aquariums = 1 pound of fish food per aquarium

Simplifying the equation, we get:

X = 1 pound of fish food / 1 pound of fish food per aquarium

X = 1 aquarium

Therefore, the pound of fish food is shared equally among 1 aquarium, and each aquarium gets 1 pound of fish food.

Answer:

Step-by-step explanation:

The two given points are (8, 0) and (8, -8).

Using the distance formula, the distance between the two points can be calculated as:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where x1 = 8, y1 = 0, x2 = 8, and y2 = -8

d = sqrt((8 - 8)^2 + (-8 - 0)^2)

d = sqrt(0 + 64)

d = sqrt(64)

d = 8

Therefore, the distance between the two points is 8 units.

Answer: (a) The probability of being male or being a nursing major is the sum of the probabilities of being male and being a nursing major, minus the probability of being both male and a nursing major (since this intersection is counted twice):

P(being male or being nursing major) = P(male) + P(nursing major) - P(male and nursing major)

From the table, we have:

P(male) = 1110/3538 ≈ 0.314

P(nursing major) = 1016/3538 ≈ 0.287

P(male and nursing major) = 94/3538 ≈ 0.027

Therefore:

P(being male or being nursing major) ≈ 0.314 + 0.287 - 0.027 ≈ 0.574

Rounded to the nearest thousandth as needed, the probability of being male or being a nursing major is approximately 0.574.

(b) The probability of being female or not a nursing major is the sum of the probabilities of being female and not a nursing major:

P(being female or not being a nursing major) = P(female) + P(not nursing major)

From the table, we have:

P(female) = 2428/3538 ≈ 0.686

P(not nursing major) = 1728/3538 ≈ 0.489

Therefore:

P(being female or not being a nursing major) ≈ 0.686 + 0.489 ≈ 1.175

This probability is greater than 1, which is not possible. Therefore, we need to subtract the probability of being both female and a nursing major (which was counted twice):

P(being female or not being a nursing major) = P(female) + P(not nursing major) - P(female and nursing major)

From the table, we have:

P(female and nursing major) = 700/3538 ≈ 0.198

Therefore:

P(being female or not being a nursing major) ≈ 0.686 + 0.489 - 0.198 ≈ 0.977

Rounded to the nearest thousandth as needed, the probability of being female or not a nursing major is approximately 0.977.

(c) The probability of not being female or a nursing major is the complement of the probability of being female or a nursing major:

P(not being female or being a nursing major) = 1 - P(being female or being nursing major)

From part (a), we have:

P(being male or being nursing major) ≈ 0.574

Therefore:

P(not being female or being a nursing major) ≈ 1 - 0.574 ≈ 0.426

Rounded to the nearest thousandth as needed, the probability of not being female or a nursing major is approximately 0.426.

(d) The events "being male" and "being a nursing major" are not mutually exclusive, because there are 94 males majoring in nursing (as shown in the table). Mutually exclusive events cannot occur at the same time, but being male and a nursing major is a possible combination. Therefore, the correct answer is OB. Yes, because there are 94 males majoring in nursing.

Answer:

Step-by-step explanation:

We can use the two given data points to find the slope of the line that represents the population growth over time.

The population at time t=3 is 1285, which means that the population has increased by P1 = 1285 - P0, where P0 is the initial population at time t=0 (which is not given). Similarly, the population at time t=8 is 2460, which means that the population has increased by P2 = 2460 - P0.

The time elapsed between t=3 and t=8 is 8-3 = 5 years.

The slope of the line that represents the population growth over time is given by:

slope = (P2 - P1) / (t2 - t1)

where t1 and t2 are the corresponding times.

Substituting the given values, we get:

slope = (2460 - 1285) / (8 - 3)

slope = 235

This means that the population is increasing by 235 people per year.

To find the initial population at time t=0, we can use either of the two given data points. Let's use the population at time t=3:

P1 = 1285 - P0

235 * 3 = 705

1285 - 705 = 580

Therefore, the initial population at time t=0 (i.e., in the year 1990) was 580 people.

We can now use the slope to find the population at any given time t after 1990.

Let P(t) be the population at time t after 1990.

Then, P(t) = P0 + slope * (t - 0)

P(t) = 580 + 235t

For example, the population in the year 2000 (i.e., when t=10) would be:

P(10) = 580 + 235(10) = 3330

Therefore, the population in the year 2000 would be 3330 people.

The simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

Recall that the secant function is defined as the reciprocal of the cosine function. In other words, sec(t) = 1/cos(t). Therefore, we can rewrite cos(t)/sec(t) as cos(t)/(1/cos(t)).

To simplify this expression, we can multiply both the numerator and the denominator by cos(t), which gives:

cos(t)/(1/cos(t)) = cos(t) * (cos(t)/1) = cos²(t)

Now, we have simplified cos(t)/sec(t) to cos²(t). Alternatively, we could have used the identity cos²(t) = 1 - sin²(t) to simplify the expression. This identity follows directly from the Pythagorean identity cos²(t) + sin²(t) = 1.

Starting with cos(t)/sec(t), we can substitute sec(t) = 1/cos(t) to get:

cos(t)/sec(t) = cos(t)/(1/cos(t)) = cos²(t)/1

Then, we can use the identity cos²(t) = 1 - sin²(t) to substitute cos²(t) in terms of sin(t):

cos(t)/sec(t) = cos²(t)/1 = (1 - sin²(t))/1 = 1 - sin²(t)

So, we have simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

What is histogram?

The histogram shows that the distribution of the data is asymmetrical, with a longer tail towards the right. This means that there are more schools that made a higher number of photocopies than those that made a lower number of photocopies. Therefore, the mean and median are likely to be higher than the midpoint of the "1,000-1,099 photocopies" category, which has the highest frequency.

In a skewed distribution, the mean is typically affected by the outliers, while the median is a better measure of central tendency. Therefore, the median is more likely to be within the "1,000-1,099 photocopies" category, while the mean is likely to be higher.

IJ is the median of the trapezoid. I is the midpoint of EH, and J is the midpoint of GF.

Also, the median of a trapezoid is also parallel to the parallel sides. IJ║ HG║ EF.

(The proof of this is extensive and requires drawing additional lines such as HJ and extending EF further until HJ and EF intersect at another point, Y. It is given as the other diagram. You also need prior knowledge of the midsegment of a triangle.)

The measure of the midsegment of a trapezoid, by definition, is also equal to the average of the measure of the parallel segments.
