Answer:

80.456 is a 9.6% decrease of 89.

Step-by-step explanation:

Answer:

Step-by-step explanation:

 89×(1-9.6%)

=89×(1-0.096)

=89×0.904

=80.456

≈80

the answer is 80 if you have to round it.

For the given scenario: the Probability of making both shots are A. 0.64 and B. 0.72

a) If a player makes 80% of his foul shots, the probability of making a single foul shot is 0.8. Since the two shots are considered independent events, the probability of making both shots is the product of the individual probabilities.

Therefore, the probability of making both shots is 0.8 * 0.8 = 0.64.

To calculate the probability of making exactly one shot, we need to consider two scenarios: making the first shot and missing the second, or missing the first shot and making the second. Each scenario has a probability of 0.8 * 0.2 = 0.16.

Therefore, the probability of making exactly one shot is 0.16 + 0.16 = 0.32.

Similarly, the probability of missing both shots is 0.2 * 0.2 = 0.04.

b) In this case, the outcome of the second shot depends on the outcome of the first shot. If the player makes the first shot (with a probability of 0.8), the probability of making the second shot is 0.9.

Therefore, the probability of making both shots is 0.8 * 0.9 = 0.72.

If the player misses the first shot (with a probability of 0.2), the probability of making the second shot is 0.7.

Therefore, the probability of making exactly one shot is 0.2 * 0.7 = 0.14.

Since there are only two possible outcomes (making both shots or making exactly one shot), the probability of neither shot being made is 1 - (0.72 + 0.14) = 0.14.

Therefore, for the given scenario:

a) Probability of making both shots: 0.64

  Probability of making exactly one shot: 0.32

  Probability of missing both shots: 0.04

b) Probability of making both shots: 0.72

  Probability of making exactly one shot: 0.14

  Probability of missing both shots: 0.14

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

8 + 7x - x² = 0 ( multiply through by - 1 and arrange into standard form )

x² - 7x - 8 = 0 ← in standard form

(x - 8)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 8 = 0 ⇒ x = 8

Answer:

x = -2

Step-by-step explanation:

-95= 14x - 7 + 30x (collect like terms)

-95 = 44x - 7 (add 7 on each side)

-88 = 44x (divide by 44 on each side)

-2 = x

Answer:

y = -2/5x + 9

Step-by-step explanation:

The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.

The value of the give expression is  \(\frac{313}{748845}\) OR 4.18 × 10⁻⁴

From the question, we are to determine the value of

2(5+34-67/45*43)^2

This can be written as

\(2 (\frac{5+34-67}{45 \times 43 })^{2}\)

First, we will simplify the bracket

\(2 (\frac{-28}{1935 })^{2}\)

Then, we get

\(2 \times \frac{-28}{1935 }\times \frac{-28}{1935 }\)

= \(\frac{1568}{3744225}\)

= \(\frac{313}{748845}\) OR 4.18 × 10⁻⁴

Hence, the value of the give expression is  \(\frac{313}{748845}\) OR 4.18 × 10⁻⁴

Option 3) Sometimes is the correct answer, Sometimes an equilateral triangle is similar to a scalene triangle.

If the respective sides are proportional and the corresponding angles are congruent, two triangles are comparable. An equilateral triangle has three congruent sides and three congruent angles, so any triangle that is similar to an equilateral triangle must also have three congruent angles. However, a scalene triangle has no congruent sides and no congruent angles, so it is possible for a scalene triangle to be similar to an equilateral triangle only if it has the same angle measurements as an equilateral triangle, but with different side lengths. Therefore, a scalene triangle can be similar to an equilateral triangle, but it is not always the case.

In general, if two triangles are similar, it means that they have the same shape but possibly different sizes. In the case of an equilateral triangle and a scalene triangle, if they are similar, then it means that the scalene triangle has the same angles as the equilateral triangle, but its sides are of different lengths. So it is possible for a scalene triangle to be similar to an equilateral triangle, but not in all cases.

The graph of the function f(x) = sin(1/2x) is attached accordingly. It is to be noted that it is erroneous to include an equal sign within the parenthesis, that is sin(1/2= x). Hence the correct function is f(x) = sin(1/2x).

A graphed function simply means drawing a graph that is representative of a mathematical function.

The task of the mathematician here is to first redefine the formula such that one can identify the:

The form to be used is:

a = 1

b= 1/2

c =0

d =0.

The absolute value of the amplitude |a| is given as
Amplitude = 1

As per the unitary method, the cost of the gift is 72 baht.

Let's begin by assigning a variable to represent the cost of the gift. Let's call it "x" baht.

According to the problem, Kitiya initially had 52 baht, and Nyaan had 32 baht. They shared the cost of the gift equally, which means each of them contributed an equal amount towards the gift.

Let's represent Kitiya's remaining money as "5r" baht, where "r" represents Nyaan's remaining money.

Based on this information, we can set up the following equation:

52 - (x/2) = 5(32 - (x/2))

Now, let's solve this equation step by step to find the value of "x."

Distribute the multiplication on the right side of the equation:

52 - (x/2) = 160 - 5(x/2)

Simplify both sides of the equation:

52 - x/2 = 160 - 5x/2

To eliminate fractions, we can multiply both sides of the equation by 2:

2(52 - x/2) = 2(160 - 5x/2)

104 - x = 320 - 5x

Combine like terms:

4x - x = 320 - 104

3x = 216

Solve for x by dividing both sides of the equation by 3:

x = 216/3

x = 72

The volume of the ring-shaped remaining solid is 1797 cm³.

The volume is the total space occupied by an object.

The volume of a sphere of radius r units is given as (4/3)πr³.

The volume of a cylinder with radius r units and height h units is given as πr²h.

In the question, we are asked to find the volume of the remaining solid when a sphere of radius 9cm is drilled by a cylindrical driller of radius 5cm.

The volume will be equal to the difference in the volumes of the sphere and cylinder, where the height of the cylinder will be taken as the diameter of the sphere (two times radius = 2*9 = 18) as it is drilled through the center.

Therefore, the volume of the ring-shaped remaining solid is given as,

= (4/3)π(9)³ - π(5)²(18) cm³,

= π{972 - 400} cm³,

= 572π cm³,

= 1796.99 cm³ ≈ 1797 cm³.

Therefore, the volume of the ring-shaped remaining solid is 1797 cm³.

The probability of an occurrence is a measure of how likely that event will occur.

The probability of an event varies between 0 and 1 or 0 and 100 percent.

The statement that "A weather forecasting website indicated that there was a 30% chance of rain in a certain region" implies that there is a probability of 0.3 or 30 percent that it will rain in the specified area.

This does not provide information about the duration of rain or the specific areas within the region that will experience rainfall.

Answer: 32w

Step-by-step explanation:

Solution 1 :
We calculate the third angle of the triangle (not x) : 180 - 80 = 100
(Note : the angle is supplementary to the 80 degree angle, so the sum of them is 180)

Now we calculate x, and since we know 3 angles in a triangle add up to 180 :

180 - 30 - 100 = 50.

Solution 2 :
If there is an angle that is outside the triangle but is supplementary to one of the angle in the triangle, it will be equal to the sum of the 2 angles which are NOT supplementary to it.

Using this, we can say 80 is equal to 30 + x (because those 2 angles are not supplementary)

So, we can find x by taking 80-30 = 50.

Answer:

La magnitud de la velocidad angular es 0.026 rad/s y la magnitud del desplazamiento angular es 4.71 rad.

Step-by-step explanation:

Podemos encontrar la magnitud de la velocidad angular (ω) del disco con la siguiente ecuación:

\( \omega = \frac{\theta}{t} \)

En donde:

θ: es el desplazamiento angular = 0.75 rev

t: es el tiempo = 180 s

Primero debemos cambiar las unidades del desplazamiento angular de revoluciones a radianes:

\( \theta = 0.75 rev*\frac{2\pi rad}{1 rev} = 4.71 rad \)

Entonces, la velocidad angular es:

\( \omega = \frac{4.71 rad}{180 s} = 0.026 rad/s \)

Por lo tanto, la magnitud de la velocidad angular es 0.026 rad/s y la magnitud del desplazamiento angular es 4.71 rad.
