The probability of digits 0 to 9 represent the medicine being not effective.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

As the digit 9 is not effective

So the number of not effective is 2+1+2+2+1+3

=11

The probability=effective numbers/all numbers

=30-11/30

=19/30

Hence, the probability of digits 0 to 9 represent the medicine being not effective.

find mGHJ in degrees inscribed angles

Answers

If the measure of the intercepted arc GHJ is 180°, the measure of the inscribed angle GHJ will be mGHJ = 360° - 180° = 180°.

What is angle?

Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.

The measure of an inscribed angle in a circle is always equal to the measure of its intercepted arc. The measure of the arc intercepted by a central angle is determined by the formula, mGHJ = 360° - mJKH. Therefore, the measure of an inscribed angle in a circle with intercepted arc GHJ is equal to mGHJ = 360° - mJKH. This means that the measure of an inscribed angle in a circle can vary depending on the measure of its intercepted arc. For example, if the measure of the intercepted arc GHJ is 180°, the measure of the inscribed angle GHJ will be mGHJ = 360° - 180° = 180°.

Answers

The vertical asymptote of the function [tex]f(x) = \frac{x^2 + 6x + 9}{x^2 - 9}[/tex] is at x = 3.

What is an asymptote?

Asymptote is a line or curve that serves as the boundary of another line or curve in mathematics.

Given, A function [tex]f(x) = \frac{x^2 + 6x + 9}{x^2 - 9}[/tex].

Factoring the numerator and the denominator we have,

[tex]f(x) = \frac{(x+3)(x+3)}{(x+3)(x-3)}[/tex]

Now, The holes of the function are at [tex]f(x) = \frac{(x+3)}{(x-3)}[/tex], x + 3 = 0, x = - 3.

Two buckets, each with a different volume of water, start leaking water at the same time, but at different rates. Assume the volumes are changing linearly.

Answers

The difference between the starting volumes is 200 milliliters, the first bucket has the larger volume.

What is the difference between the starting volumes?

We know that the volumes can be modeled by linear equations, and remember that a general linear equation is:

y = a*x + b

Where a is the slope and b is the initial value.

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

For the first bucket we have the points (1, 2900), (10, 2000), then the slope is:

a = (2000 - 2900)/(10 - 1) = -900/9 = -100

So we can write:

y = -100*x + b

To find the value of b, we can replace the value of one of the points in the equation. I will use the first point (1, 2900)

2900 = -100*1 + b

2900 + 100 = b

3000 = b

Now for the other bucket, we have the points (1, 2725) and (10, 2050), so the slope is:

a = (2725 - 2050)/(10 - 1) = -75

So this line is:

y = -75*x + b

Again, replacing the values of one of the points we will get:

2725 = -75*1 + b

2725 + 75 = b

2800 = b

Then the difference in the starting volumes is:

3000  - 2800 = 200

The first bucket has 200 milliliters more.

Mr.Aba builds a circular patio with a diameter of 12 feet.He covers the patio with paving stones.The cost of the paving stones is $10.50 per square foot.To the nearest dollar,how much do the paving stones cost?

Answers

The total cost of the paving stones for building a circular patio with a diameter of 12 feet is C. $1,187.

How is the total cost determined?

The area of the circular patio using its diameter and pi (22/7) is determined with the formula below.

The unit cost per square foot is multiplied by the area to determine the total cost.

A = π (d/2)^2

The diameter of a circular patio = 12 feet

The area, A = π (d/2)^2

= 22/7(12/2)^2

= 113.14 ft²

The cost per square foot of paving stones = $10.50

The total cost = $1,187.97 ($10.50 x 113.14)

= $1,188

Thus, using the mathematical operation of multiplication, we can conclude that Mr. Aba's project will cost Option C.

The rock will be 9 meters from ground level at a time of:

x = 5.76 seconds.

How to model the situation?

The quadratic function that models a projectile's height is given as follows:

y = -4.9t² + v(0)t + h(0)

In which:

v(0) is the initial velocity.h(0) is the initial height.

The parameters for this problem are given as follows:

v(0) = 22, h(0) = 45.

Hence the height function is given as follows:

y = -4.9t² + 22t + 45.

The rock is 9 meters from ground level when:

9 = -4.9t² + 22t + 45.

-4.9t² + 22t + 36 = 0

4.9t² - 22t - 36 = 0.

Hence the discriminant is given as follows:

D = 22² - 4(4.9)(-36)

D = 1189.6.

If n is an integer and m + 5 is odd, then n must be even.

To prove this statement using contraposition, we need to show that if n is odd, then m + 5 must be even. Assume that n is odd, which means we can write n = 2k + 1 for some integer k.

Then, we can rewrite m + 5 as (2k + 1) + 5 = 2k + 6 = 2(k + 3), which is even.

Therefore, we have shown that if n is odd, then m + 5 is even.

By contraposition, we can conclude that if m + 5 is odd, then n must be even. Overall, the proof uses the fact that odd + odd = even and even + odd = odd, along with the definition of even and odd integers.

A total of 3 ft falls over 3 days. On the first day, 1/6 of the total rain falls. On the second day, 7/12 of the total rain falls. How much rain falls each day in inches? Show your work. Please help.

Answers

Answer:

Day 1: 6 inches

Day 2: 21 inches

Day 3: 9 inches

Step-by-step explanation:

First, we need to convert the total rainfall from feet to inches. Since 1 foot is equal to 12 inches, 3 feet is equal to 36 inches.

On the first day, 1/6 of the total rainfall falls, so:

(1/6) * 36 = 6 inches

On the second day, 7/12 of the total rainfall falls, so:

(7/12) * 36 = 21 inches

To find the rainfall on the third day, we can subtract the rainfall on the first and second days from the total rainfall:

36 - 6 - 21 = 9 inches

Therefore, the amount of rainfall on each day, in inches, is:

Day 1: 6 inches

Day 2: 21 inches

Choose 1 answer:
WILL GIVE ALL MY PONITS

Answers

Answer:

Veronica's attempt at ordering the hikes from least to greatest by the number of animals seen per kilometer is not correct.

To order the hikes by the number of animals seen per kilometer, we need to calculate the number of animals seen per kilometer for each hike. We can do this by dividing the number of animals seen by the length of the hike in kilometers.

Using this method, we can calculate the number of animals seen per kilometer for each hike as follows:

Rivers Edge: 8/3 = 2.67 animals/km

Wooded Marsh: 24/8 = 3 animals/km

Canyon Creek: 35/15 = 2.33 animals/km

Based on these calculations, the correct order of the hikes from least to greatest by the number of animals seen per kilometer is Rivers Edge, Canyon Creek, Wooded Marsh.

Veronica's mistake appears to be that she simply ordered the number of animals seen in each hike from least to greatest, rather than calculating the number of animals seen per kilometer.
