If  a deadly disease infected the hummingbird population, what would most likely happen to the plants option (b) They would become endangered

If a deadly disease infected the hummingbird population, it would most likely lead to a decrease in the pollination of plants that rely on hummingbirds for pollination. Without the hummingbirds to transfer pollen between flowers, these plants would have a reduced rate of successful pollination, which would result in a decrease in their ability to reproduce.

However, it is unlikely that the plants would die within hours or become endangered immediately, nor would they need to migrate. The effect of the loss of hummingbird pollinators on the plants would depend on the specific plant species, their pollination requirements, and the availability of alternative pollinators. Some plants may be more adaptable to using alternative pollinators, while others may suffer more severe consequences. It is also possible that the loss of hummingbirds could lead to a decline in the populations of other animals that depend on the plants, creating a ripple effect in the ecosystem.

Therefore, the correct option is (d) They would become endangered

The probability of a female employee driving to work is 0.192, or 19.2%.

To determine the probability of a female employee driving to work, we need to find the intersection of the categories "female" and "drive" in the given table.

From the table, we have the following probabilities:

P(female) = 0.4 (probability of being female)

P(drive) = 0.48 (probability of driving to work)

P(female and drive) = ? (probability of being female and driving to work)

We can calculate the probability of being female and driving to work by multiplying the individual probabilities:

P(female and drive) = P(female) * P(drive) = 0.4 * 0.48 = 0.192

Therefore, the probability of a female employee driving to work is 0.192, or 19.2%.

Step-by-step explanation:

To find the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2, we can use the following formulas:

New x-coordinate = -2 * old x-coordinate

New y-coordinate = -2 * old y-coordinate

Let's apply these formulas to each point in triangle ABC:

Point A: (-3, 4)

New x-coordinate of A = -2 * (-3) = 6

New y-coordinate of A = -2 * 4 = -8

New coordinates of A: (6, -8)

Point B: (1, 1)

New x-coordinate of B = -2 * 1 = -2

New y-coordinate of B = -2 * 1 = -2

New coordinates of B: (-2, -2)

Point C: (5, -2)

New x-coordinate of C = -2 * 5 = -10

New y-coordinate of C = -2 * (-2) = 4

New coordinates of C: (-10, 4)

Therefore, the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2 are:

A: (6, -8)

B: (-2, -2)

C: (-10, 4)

Explanation:

The angles SPT and TPU marked in red are congruent. They are congruent because of the similar arc markings.

Those angles add to the other angles to form a full 360 degree circle.

Let x be the measure of angle SPT and angle TPU.

86 + 154 + 60 + x + x = 360

300 + 2x = 360

2x = 360-300

2x = 60

x = 60/2

x = 30

Each red angle is 30 degrees.

Then,

angle SPQ = (angle SPT) + (angle TPU) + (angle UPQ)

angle SPQ = (30) + (30) + (86)

angle SPQ = 146 degrees

--------------

Another approach:

Notice that angles QPR and RPS add to 154+60 = 214 degrees, which is the piece just next to angle SPQ. Subtract from 360 to get:

360 - 214 = 146 degrees

Step-by-step explanation:

Coordinates of the centroid of a triangle with given vertices (x₁, y₁), (x₂, y₂) and (x₃, y₃) is given by,

X-coordinates = \(\frac{x_1+x_2+x_3}{3}\)

Y-coordinates = \(\frac{y_1+y_2+y_3}{3}\)

For the given triangle FGH,

Coordinates of the vertices are,

F(-3, 1), G(2, 6) and H(4, 1)

X-coordinate of the centroid = \(\frac{-3+2+4}{3}\) = 1

Y-coordinate of the centroid = \(\frac{1+6+1}{3}\) = \(\frac{8}{3}\)

Therefore, coordinates of the centroid will be (1, \(\frac{8}{3}\) )

The area of the rectangle is 0.4 square meters

To find the area of a rectangle, we multiply its length by its breadth.

Given:

Length = 20 m

Breadth = 2 cm

We need to ensure that the units for length and breadth are consistent. Since the breadth is given in centimeters (cm), we need to convert it to meters (m) before calculating the area.

1 cm = 0.01 m

Converting the breadth from centimeters to meters:

Breadth = 2 cm * 0.01 m/cm = 0.02 m

Now we can calculate the area of the rectangle:

Area = Length * Breadth = 20 m * 0.02 m

Area = 0.4 m^2

Therefore, the area of the rectangle is 0.4 square meters (m^2).

The volume of the cone is approximately 81.249 cm³, rounded to three significant figures. To calculate the volume of a cone, we need to know the slant height and the radius or height of the cone.

However, in this case, we are only given the slant height and the curved surface area of the cone.

Given:

Slant height (l) = 9 cm

Curved surface area (CSA) = 100 cm²

We can start by finding the radius (r) of the cone using the formula for curved surface area:

CSA = π * r * l

Plugging in the given values:

100 = π * r * 9

To solve for r, we can divide both sides of the equation by 9π:

r = 100 / (9π)

Now that we have the radius, we can calculate the volume (V) of the cone using the formula:

V = (1/3) * π * r² * h

Since we don't have the height (h) of the cone, we can express it in terms of the slant height and radius using the Pythagorean theorem:

h = sqrt(l² - r²)

Plugging in the values:

h = sqrt(9² - (100 / (9π))²)

Now we have all the necessary values to calculate the volume:

V = (1/3) * π * r² * h

V = (1/3) * π * (100 / (9π))² * sqrt(9² - (100 / (9π))²)

Calculating the value using a calculator or software, we find:

V ≈ 81.249 cm³

Therefore, the volume of the cone is approximately 81.249 cm³, rounded to three significant figures.

Answer:

x = 10°

Step-by-step explanation:

a). Since, opposite angles of a cyclic quadrilateral are supplementary angles"

   Therefore, in cyclic quadrilateral ABDE,

   m∠ABD + m∠AED = 180°

   110° + m∠AED = 180°

   m∠AED = 180° - 110°

                 = 70°

b). AD = ED [Given]

   m∠EAD = m∠AED [Since, opposite angles of equal sides are equal in measure]

   m∠EAD = m∠AED = 70°

   By triangle sum theorem in ΔABD,

   m∠BAD + m∠ABD + m∠ADB = 180°

   m∠BAD + 110° + 40° = 180°

   m∠BAD = 180 - 150

                 = 30°

    m∠AEB = m∠AED + m∠DAB [By angles addition postulate]

    m∠AEB = 70° + 30°          

                  = 100°

    By triangle sum theorem in the large triangle,

    x° + m∠AEB + m∠EAB = 180°

    x° + 100° + 70° = 180°

    x = 180 - 170

    x = 10°

LCL and UCL values of both scenarios are (158.61,161.39),(69.65,70.35) respectively.

To calculate the lower confidence limit (LCL) and upper confidence limit (UCL) for each given scenario, you'll need to use the following formula:

LCL = X - (z * (sigma / √n))
UCL = X+ (z * (sigma / √n))

where X is the sample mean, n is the sample size, sigma is the population standard deviation, and z is the z-score corresponding to the desired confidence level (1 - alpha).

First Scenario:
X = 160, n = 436, sigma = 30, alpha = 0.01

1. Find the z-score for the given alpha (0.01).
For a two-tailed test, look up the z-score for 1 - (alpha / 2) = 1 - 0.005 = 0.995.
The corresponding z-score is 2.576.

2. Calculate LCL and UCL.
LCL = 160 - (2.576 * (30 / √436)) ≈ 158.61
UCL = 160 + (2.576 * (30 / √436)) ≈ 161.39

First Scenario Result:
LCL = 158.61
UCL = 161.39

Second Scenario:
X= 70, n = 323, sigma = 4, alpha = 0.05

1. Find the z-score for the given alpha (0.05).
For a two-tailed test, look up the z-score for 1 - (alpha / 2) = 1 - 0.025 = 0.975.
The corresponding z-score is 1.96.

2. Calculate LCL and UCL.
LCL = 70 - (1.96 * (4 / √323)) ≈ 69.65
UCL = 70 + (1.96 * (4 / √323)) ≈ 70.35

Second Scenario Result:
LCL = 69.65
UCL = 70.35
