Answer:

-18

Step-by-step explanation:

I just had this question and the answer is -18 because 3x+21-21=-31-21 to get - 18

Answer:

A). X = -18

Step-by-step explanation:

-18 times 3 + 21 is -33. When you have a hard time figuing out these sort of problems, I suggest you should get each choice that is given. Put one of these choices one at a time in the equation and see if it will equal -33. To do this, you put the number and substiture it for x. This is an easy way of solving this problem especially when it is multiple choice.

The relationship between Priscilla's and Mary's age illustrates algebraic expression

The correct representation of the statements is b - k = 15

From the question, we have:

Priscilla = k

Mary = b

Mary = 15 years older

The third highlight above means that:

Mary = 15 + k

Substitute b for Mary

b = 15 + k

Subtract k from both sides

b - k = 15

Hence, the correct representation of the statements is b - k = 15

The sample has a 5/1938 chance of having all four colors represented.

The probability is a measure of the possibility that an event will occur. It assesses the event's certainty. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the probability formula. The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

Here,

a box contains 7 white balls and 8 black balls. if 3 balls are drawn from the box at random,

=10/20*5/19*3/18*2/17

=5/1938

The probability that all four colors will be represented in the sample is 5/1938.

Basis for the set of all vectors in the given format is (0, 1, 5)

To find a basis for the set of all vectors in the given format, we need to simplify and organize the terms. Rearranging the terms, we get:
(-2b + 5b - 4b + b) + (2a + 3a) + (5c - 8c + 7c + c)
Simplifying further, we get:
0a - 0b + 5c = 5c
This means that any vector in this set can be represented as a linear combination of (0, 1, 5). Therefore, (0, 1, 5) is a basis for this set.
To verify that this is indeed a basis, we need to show that (0, 1, 5) is linearly independent and spans the set.
Linear independence means that there are no non-zero coefficients such that a(0, 1, 5) = (0, 0, 0). Clearly, a cannot be zero, as that would make the vector the zero vector. Solving for a, we get:
a(0, 1, 5) = (0, 0, 0)
a(0) + a(1) + a(5) = 0
a = 0
Therefore, (0, 1, 5) is linearly independent.
To show that it spans the set, we need to show that any vector in the set can be expressed as a linear combination of (0, 1, 5). We already showed that any vector can be written as 5c(0, 1, 5), so this is true.
(0, 1, 5) is a basis for the set of all vectors in the given format.

Answer:

Step-by-step explanation:

Let x be the random variable representing the height of the students. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 68.5

σ = 2.7

the probability that a student's height is between 67.5 and 71.0 inches exclusive is expressed as

P(67.5 < x < 71.0)

For x > 67.5,

z = (67.5 - 68.5)/2.7 = - 0.37

Looking at the normal distribution table, the probability corresponding to the z score is 0.36

For x < 71.0

z = (71.0 - 68.5)/2.7 = 0.93

Looking at the normal distribution table, the probability corresponding to the z score is 0.82

Therefore,

P(67.5 < x < 71.0) = 0.82 - 0.36 = 0.46

The number of students whose height is between 67.5 and 71.0 inches is

0.46 × 1000 = 460 students

The probability that a student's height is greater than or equal to 74.0 inches is expressed as P(x ≥ 74)

P(x ≥ 74) = 1 - P(x < 74)

For x < 74,

z = (74 - 68.5)/2.7 = 2.04

Looking at the normal distribution table, the probability corresponding to the z score is 0.98

P(x ≥ 74) = 1 - 0.98 = 0.02

The number of students whose height are greater than or equal to 74.0 inches is

0.02 × 1000 = 20 students

The value of x that makes 25x^2 + 70x + c a perfect square trinomial is c = 1225.

To make the quadratic expression 25x^2 + 70x + c a perfect square trinomial, we need to determine the value of c.

A perfect square trinomial can be written in the form (ax + b)^2, where a is the coefficient of the x^2 term and b is half the coefficient of the x term.

In this case, a = 25, so b = (1/2)(70) = 35.

Expanding (ax + b)^2, we have:

(25x + 35)^2 = 25x^2 + 2(25)(35)x + 35^2

= 25x^2 + 70x + 1225.

Comparing this with the given quadratic expression 25x^2 + 70x + c, we can see that c = 1225.

The above obtained relation can be used to find df(0) / dz as we now have df/dr (dr/dz) evaluated at z=0. Thus,df(0) / dz = 2 * 0 / (-dx - 2jdx) = 0. Hence, the required solution is df(0) / dz = 0.

Given complex function is f(z) = x2 + jy2. We are supposed to find df(0) / dz.Solution:To find df(0) / dz, we need to first find f(z) as a function of z. Since, f(z) = x2 + jy2, we have, f(z) = |z|2. Now, we have, |z|2 = (x+iy) (x-iy) = x2 + y2 = r2. Differentiating this with respect to z, we get,df / dz (|z|2) = df / dz (r2) = 2r dr/dz. Now, we need to find dz. This can be found using the following relation, dz = dx + jdy.

Thus, we have,dz = dx + jdy = 1/2 (dz + d\bar{z}) + j 1/2 (dz - d\bar{z}) = (dx - dy)/2 + j (dx + dy)/2. 

Therefore,

df/dz = df/dr (dr/dz)

= 2r / (dx - dy - 2jdx). T

he above obtained relation can be used to find df(0) / dz as we now have df/dr (dr/dz) evaluated at z=0.

Thus, df(0) / dz = 2 * 0 / (-dx - 2jdx) = 0. Hence, the required solution is df(0) / dz = 0.

To find df(0) / dz, we need to first find f(z) as a function of z.

Since, f(z) = x2 + jy2,

we have, f(z) = |z|2.

Now, we have, |z|2 = (x+iy) (x-iy) = x2 + y2 = r2.
