Answer:

Step-by-step explanation:

No. The sample size for drug Y is large enough, but the sample size for drug X is not.

The sample size would be greater than 100 to get a significant result, so, option C is correct.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

A random sample of 75 people using drug X and a random sample of 150 people using drug Y is selected,

The majority of statisticians concur that a sample size of 100 is necessary to obtain any form of significant results. If your population is less than 100, you should definitely survey every single person.

Thus, the sample size for drug X is not enough.

The solution for x, y, and z is x = 2, y = 2, and z = 2.

To solve the equation (35)"4(23)"5(25)"7 = 2"x3"y*5"z, let's break it down step by step:

Simplify the expressions within the parentheses using the power of operator ("^").

\((35)"4 = 15^4\\(23)"5 = 6^5\\(2\times5)"7 = 10^7\)

Apply the power rule of exponents, which states that \((a^b)^c = a^{(b\times c).\)

\(15^4 \times 6^5 \times 10^7 = (15610)^{(4+5+7)\)

Simplify the expression within the parentheses.

\((15610)^{16 }= 900^{16\)

Express both sides of the equation in terms of prime factors.

\(900 = 2^2 \times 3^2 \times 5^2\)

quate the powers of the prime factors on both sides of the equation.

\(2^2 \times 3^2 \times 5^2 = 2"x \times 3"y \times 5"z\)

From this, we can conclude that x = 2, y = 2, and z = 2.

Therefore, the solution for x, y, and z is x = 2, y = 2, and z = 2.

True, While "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.

The statement "-1000 2/3 is not a real fraction" is true. A real fraction is a mathematical expression that represents a ratio of two real numbers. In a fraction, the numerator and denominator are both real numbers, and they can be positive, negative, or zero.

In the given statement, "-1000 2/3" is not a valid representation of a fraction. The presence of a space between "-1000" and "2/3" suggests that they are separate entities rather than being part of a single fraction.

To represent a mixed number (a whole number combined with a fraction), a space or a plus sign is typically used between the whole number and the fraction. For example, a valid representation of a mixed number would be "-1000 2/3" or "-1000 + 2/3". However, without the proper formatting, "-1000 2/3" is not considered a real fraction.

It's important to note that "-1000 2/3" can still be expressed as an improper fraction. To convert it into an improper fraction, we multiply the whole number (-1000) by the denominator of the fraction (3) and add the numerator (2). The result would be (-1000 * 3 + 2) / 3 = (-3000 + 2) / 3 = -2998/3.

In conclusion, while "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

Answer:

36.5 cm

Step-by-step explanation:

The Adjacent leg is 36.5 cm

"The trigonometric functions (also called circular functions, angle functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths."

"In a right angled triangle, the hypotenuse is the longest side, an opposite side is the one across from a given angle, and an adjacent side is next to a given angle."

We have

Hypotenuse (AB) = 58 cm

Angle θ = 51 degree

From the figure, by using trigonometric functions

Cos θ = \(\frac{BC}{AB}\)

we have to find BC

Cos \(51^{0}\) = \(\frac{BC}{AB}\)

We have, AB = 58 cm

BC = AB cos \(51^{0}\)

⇒BC = 58 . cos \(51^{0}\)

⇒BC = 36.50 cm

⇒BC = 36.5 cm

According to the provided statement, the parallelogram's other three angles' measurements are 40°,140°,40°

It is impossible for a trapezoid to be a parallelogram. Whereas a parallelogram has two sets of parallel sides, a trapezoid only has one pair. An object with two pairs of two edges is referred to as a parallelogram. All rhombuses are parallelograms because their opposite sides are all the same length.

A parallelogram's sum of neighboring angles is 180°.

So,

140+ x° = 180°

The length of side b of the given right angle triangle using law of sines is; b = 12.044 m

The law of sines states that when we divide side "a" by the sine of angle A, it is equal to side "b" divided by the sine of angle B, and also equal to side "c" divided by the sine of angle C

Thus;

a/sin A = b/sin B = c/sinC

The parameters are;

B = 42°

c = 18m

Since c is the hypotenuse, it is the side that will be opposite the right angle and so;

C = 90°

Thus, using sine rule;

c/sinC = b/sin B

18/sin 90 = b/sin 42

b = (18 * sin 42)/1

b = 12.044 m

If \(k\in\mathbb{Z}\) than \(k+1\in\mathbb{Z}\) however any \(\mathbb{Z}\) divided by 2 is in \(\mathbb{Q}\).

But it is not so simple.

If \(k\) is odd then \(k+1\) is even but when even number is divided by 2, you get an odd number which is in \(\mathbb{Z}\).

However if \(k\) is even then \(k+1\) is odd and when we divide that by 2, you get a number like for example \(\frac{5}{2}\) which is not in \(\mathbb{Z}\) but rather inside \(\mathbb{Q}\). There are fortunately no irrational numbers.

There is also a problem with zero, zero is neither odd nor even but still an integer. If your \(k\) happens to be -1, \(k+1=0\), and zero divided by 2 is still just 0 which is in \(\mathbb{Z}\).

So to sum up,

If \(k\) is odd and not -1, then \(\frac{k+1}{2}\in\mathbb{Z}\).

Or to put it in math \(\forall k\in\mathrm{odd}-\{-1\}\cup\{0\}\implies\frac{k+1}{2}\in\mathbb{Z}\).

If \(k\) is even or -1, then \(\frac{k+1}{2}\in\mathbb{Q}\).

Or to put it in math \(\forall k\in\mathrm{even}\cup \{-1\}\implies\frac{k+1}{2}\in\mathbb{Q}\).

Notes:

\(\mathbb{Z}\) is a set of integers.

\(\mathbb{Q}\) is a set of rational numbers.

\(\mathbb{Z}\subset\mathbb{Q}\) means integers are a subset of rational numbers, that is, every integer is a also a fraction, however not every fraction is an integer.

In a direct variation, y=9 when x=3. A direct variation equation that shows the relationship between x and y is y=3x

What do you mean by direct variation?

Direct variation is a type of proportionality when one quantity changes right away in reaction to a change in another variable. This implies that if one number rises, the other will follow suit in a comparable manner. Similar to the last illustration, if one quantity decreases, the other quantity also decreases. Direct variation will have a linear relationship with the graph, resulting in a straight line.

Given,

In a direct variation, y=9 when x=3.

Formulate an equation based on the conditions stated: y=kx

We put the value of the y and x in this equation

9=k*3

Subtract the coefficient of the variable from both sides of the equation

k= 3

We can write the equation of the function by putting the value of k:  y=3x

Hence the correct answer is y=3x
