We can estimate that approximately 14.17% of students in the district are interested in playing hockey.

Total interested students = 0.1417 x 4,000 = 567.

An average proportion is the sum of a set of proportions divided by the number of proportions.

It represents the average or typical value of the proportions in the set, and can be used to estimate the overall proportion or percentage of a larger population

To estimate the total number of students in the district who are interested in playing hockey, we can first find the proportion of students in each sample who said yes, and then use the average proportion across all four samples to estimate the proportion of students in the district who are interested.

Finally, we can multiply this proportion by the total number of students in the district to estimate the total number of interested students.

The proportion of students in each sample who said yes is:

Sample 1: 4/30 = 0.1333

Sample 2: 5/30 = 0.1667

Sample 3: 5/30 = 0.1667

Sample 4: 3/30 = 0.1000

The average proportion across all four samples is:

(0.1333 + 0.1667 + 0.1667 + 0.1000) / 4 = 0.1417

To estimate the total number of interested students, we can multiply this proportion by the total number of students in the district: Total interested students = 0.1417 x 4,000 = 567.

Answer:

The angle measures from least to greatest are 30°, 30° and 120°.

Step-by-step explanation:

The interior angles of a triangle sum to 180°.

Given the ratio of the interior angles of a triangle is 1 : 1 : 4 then:

x + x + 4x = 180°

Solve the equation for x:

⇒ 6x = 180°

⇒ x = 30°

Therefore, the angle measures are:

So the angle measures from least to greatest are 30°, 30° and 120°.

Answer:

30 , 30 , 120 .

Step-by-step explanation:

Given :

To find :

Solution :

As we know that the angle sum property is 180° , that is the sum of all the interior angles is 180° .

Let us take the given ratio to be 1x:1x:4x .

Sum of these= 1x + 1x + 4x = 6x .

So we can create a equation as ,

==> 6x = 180°

==> x = 180°/6

==> x = 30°

Now we can find the angles as ,

Hence the angles of the triangle are 30° , 30° and 120° .

The probability that at least two of the six members of a family are not born in the fall is approximately 0.66.

Since there are four seasons and each season has an equal probability of containing a randomly selected person's birthday, the probability that a person's birthday is not in the fall is 3/4. Therefore, the probability that all six family members are born in a season other than fall is (3/4)⁶, which is approximately 0.18.

The probability that only one family member is born in the fall is 6*(1/4)*(3/4)⁵, which is approximately 0.41. To find the probability that at least two family members are not born in the fall, we can subtract the probability that all six are born in the fall or only one is born in the fall from 1: 1 - 0.18 - 0.41 = 0.41.

In conclusion, the chance of having at least two out of the six family members not born in the fall is roughly 66%.

sorry if it's wrong. Hope this helps!

Step-by-step explanation:

The circumference of the outer circle is 72 and circumference of the inner circle is 66.Therefore, the circumference of the outer circle is 6ft greater than the circumference of the inner circle.

We know that the circumference of a circle is given by the formula C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

Given that the circumference of the inner circle is 66ft, we can find its radius by dividing the circumference by 2π:

r = C/2π = 66/(2π) ≈ 10.52ft

The distance between the inner and outer circles is 3ft, so the radius of the outer circle is 3ft greater than the radius of the inner circle:

r_outer = r_inner + 3ft = 10.52ft + 3ft = 13.52ft

Now, we can find the circumference of the outer circle using the same formula as before:

C_outer = 2πr_outer ≈ 72ft

Finally, to find the difference between the circumference of the outer circle and the circumference of the inner circle, we subtract the circumference of the inner circle from the circumference of the outer circle:

C_difference = C_outer - C_inner ≈ 72ft - 66ft = 6ft

Therefore, the circumference of the outer circle is 6ft greater than the circumference of the inner circle.

Given the following data:

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.

From the graph of the data, we have the following linear equation:

[tex]y=\dfrac{1}{2}x+18[/tex]

Substituting the value of x, we have:

[tex]y=(\dfrac{1}{2}\times40)+18[/tex]

[tex]\bold{y = 38 \ inches.}[/tex]

the length of the hall is 35 m and the breadth of the hall is 160 m.

To find the length and breadth of the drawing, we need to use the scale given. We know that 1 cm represents 5 m, so we can use this proportion to find the actual dimensions of the school compound:

1 cm : 5 m = x cm : y m

To find the length of the drawing, we can use the given dimensions of the football field, which are 50 m by 30 m:

Length of the drawing = 50 m / 5 m per cm = 10 cm

Breadth of the drawing = 30 m / 5 m per cm = 6 cm

Therefore, the length of the drawing is 10 cm and the breadth of the drawing is 6 cm.

To find the actual length and breadth of the hall, we need to use the scale given. We know that 7 cm represents the length and 32 cm represents the breadth:

Length of the hall = 7 cm x 5 m per cm = 35 m

Breadth of the hall = 32 cm x 5 m per cm = 160 m

Therefore, the length of the hall is 35 m and the breadth of the hall is 160 m.

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

Therefore, the coordinates of the image point B' are (3, -4) when a triangle ABC has points A(2, -4) B(-3, 1) C(-2, -6).

To find the image of point B after performing the given transformations, we need to apply them in sequence.

Reflection over the y-axis:

This transformation will change the sign of the x-coordinate of point B, while leaving the y-coordinate unchanged. Therefore, the image of point B after reflection over the y-axis is (-(-3), 1), which simplifies to (3, 1).

Rotation 90° clockwise:

This transformation will swap the x and y-coordinates of the point and then change the sign of the new x-coordinate. Therefore, the image of point B after rotation 90° clockwise is (1, -3).

Translation (x + 2, y - 1):

This transformation will shift the image of point B two units to the right and one unit down. Therefore, the final image of point B after all three transformations is (1 + 2, -3 - 1), which simplifies to (3, -4).

Therefore, the coordinates of the image point B' are (3, -4).

Option B is best represents for the answer. A. 84.13%. B. 15.87%. 99.87%. D. 81.86%. To create the distribution curve, we can use the normal distribution formula:  [tex]f(x) = (1/σ√(2π)) * e^(-0.5((x-μ)/σ)^2)[/tex]

where:

f(x) = probability density function at value x

μ = mean = 16.2

σ = standard deviation = 0.3

Using this formula, we can calculate the probabilities for the given scenarios:

a. Probability of a coke having less than 16.5 ounces:

We need to find P(X < 16.5), where X is the volume of the coke in ounces.

Using the z-score formula, we can standardize the value of 16.5:

z = (16.5 - 16.2) / 0.3 = 1

P(Z < 1) = 0.8413

Therefore, the probability of a coke having less than 16.5 ounces is 84.13%.

b. Probability of a coke having less than 15.9 ounces:

We need to find P(X < 15.9), where X is the volume of the coke in ounces.

Using the z-score formula, we can standardize the value of 15.9:

z = (15.9 - 16.2) / 0.3 = -1

P(Z < -1) = 0.1587

Therefore, the probability of a coke having less than 15.9 ounces is 15.87%.

c. Probability of a coke having more than 15.3 ounces:

We need to find P(X > 15.3), where X is the volume of the coke in ounces.

Using the z-score formula, we can standardize the value of 15.3:

z = (15.3 - 16.2) / 0.3 = -3

P(Z > -3) = 0.9987

Therefore, the probability of a coke having more than 15.3 ounces is 99.87%.

d. Probability of a bag having between 15.9 and 16.8 ounces:

We need to find P(15.9 < X < 16.8), where X is the volume of the coke in ounces.

Using the z-score formula, we can standardize the values of 15.9 and 16.8:

z1 = (15.9 - 16.2) / 0.3 = -1

z2 = (16.8 - 16.2) / 0.3 = 2

P(-1 < Z < 2) = 0.8186

Therefore, the probability of a coke having a volume between 15.9 and 16.8 ounces is 81.86%.

According to the given information, We will use a right-tailed test. The critical [tex]$z$[/tex]-value is [tex]$z_\alpha = 1.645$[/tex] and the test value is 1.77.

What is right-tailed test?

A right-tailed test, also known as a one-tailed test, is a statistical hypothesis test where the alternative hypothesis is directional and is expressed as an inequality with the greater-than symbol (>), indicating that the parameter being tested is expected to be larger than a specified value.

(a) The null hypothesis [tex]($H_0$)[/tex] and alternative hypothesis [tex]($H_a$)[/tex] are:

[tex]$H_0: \mu = 25$[/tex] (the addition of the mineral does not increase the number of pages read per day)

[tex]$H_a: \mu > 25$[/tex] (the addition of the mineral increases the number of pages read per day)

We will use a right-tailed test because the alternative hypothesis is one-sided (i.e., [tex]$\mu$[/tex] is greater than the hypothesized value).

(b) The critical [tex]$z$[/tex]-value for a one-tailed test with a 5% significance level and 29 degrees of freedom ([tex]df=n-1$, where $n=30$[/tex]) is:

[tex]$z_\alpha = 1.645$[/tex] (from the standard normal distribution table or calculator)

(c) The test value ([tex]$z$[/tex]-value) can be calculated as:

[tex]$z = \frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}}}$$[/tex]

where [tex]$\bar{x}$[/tex] is the sample mean, [tex]$\mu$[/tex] is the hypothesized population mean, [tex]$\sigma$[/tex] is the population standard deviation, and [tex]$n$[/tex] is the sample size.

Plugging in the values, we get:

[tex]$z = \frac{25.5 - 25}{\frac{2.4}{\sqrt{30}}} \approx 1.77$$[/tex]

The test value (1.77) is greater than the critical [tex]$z$[/tex]-value (1.645), so we reject the null hypothesis and conclude that the addition of the mineral is effective in increasing the number of pages read per day.
