What is negative 1/3 plus positive 16/20?
(I need this answer ASAP!!!!!!)

Answer:

A

Step-by-step explanation:

x≥1

∠A and ∠B are vertical angles having m∠A = x and m∠B = 4x - 30 the result of ∠A = 10.

When two lines intersect at a location, vertical angles are generated. They are always on equal footing. In other words, four angles are generated anytime two lines cross or intersect. We can see that two opposed angles are equal, and these are referred to as vertical angles.

∠B= 4x - 30.

∠A = x

∠A and ∠B are vertical angles

so,

∠A =∠B

  x = 4x - 30

4x - x = 30

3x = 30

 x = 10

m ∠A= x = 10

m ∠A = 10

∠A and ∠B are vertical angles having m∠A = x and m∠B = 4x - 30 the result of ∠A = 10.

The probability of drawing a mean with a sample mean between $100 and $115 is 0.99705.

Fee per student = $110

Standard deviation = $18

Random sample size =- 49

Sample mean difference =  $100 and $115.

This problem is calculated by using the central limit theorem, which defines that the distribution of sample average from a large sample size will be normal, however, the distribution of the population will be drawn.

For a sample size of 49, the standard error of the mean will be:

SE  = σ / sqrt(n)  

SE  = 18 / sqrt(49)

SE = 18 / 7

SE = 2.57

The standardized sample mean range of $100 to $115 using the formula for the z-score:

z = (x - μ) / SE

For a lower limit of $100:

z1 = ($100 - $110) / 2.57 = -3.89

For an upper limit of $115:

z2 = ($115 - $110) / 2.57 = 1.95

Probability = P(-3.89 < z < 1.95)

Probability = 0.9971 - 0.00005

Probability = 0.99705

Therefore, we can conclude that the probability of drawing a mean with a sample mean between $100 and $115 is 0.99705.

Step-by-step explanation:

The graph has a closed circle at x = 1 meaning x can equal - 1

Thus it must be an inequality involving ≤ or ≥

Since the arrow points to the left then it must be ≤

Step-by-step explanation:

So if they have the same slope but different y-intercepts, it would be parallel because the slope stays the same so the line doesnt change, just the starting point

For example use the following equations

y = x + 3  

In the graph, these equations are parallel

If we denote the probability of hitting a bullseye on a dartboard with radius 12 inches as a function of the size of the bullseye, we can refer to this function as PS.

The function PS represents the probability of hitting the bullseye and is dependent on the size of the bullseye. The larger the bullseye, the higher the probability of hitting it, and vice versa. By adjusting the size of the bullseye, we can determine the corresponding probability of hitting it using the function PS.

It's important to note that without specific information about the relationship between the bullseye size and the probability, it's not possible to provide a specific mathematical expression or further details about the PS function. The function would need to be defined or provided to calculate the probability accurately.

The 2 given lines with the given coordinates when analyzed are seen to be; Parallel

The formula to find the slope of a line passing through two coordinates is;

m = (y2 - y1)/(x2 - x1)

Slope of Line 1 which has coordinates of (-1, 9) and (-6, -6) is;

m1 = (-6 - 9)/(-6 - (-1))

m1 = -15/-5

m1 = 3

Slope of Line 2 which has coordinates of (-7, -23) and (0, -2) is;

m2 = (-2 - (-23))/(0 - (-7))

m2 = 21/7

m2 = 3

Lisa's percentile rank will be 89%.

What is percentile?

The k-th percentile is the score at or below which a given percentage falls, or the score below which a particular percentage of the scores in the frequency distribution falls.

The percentile rank is utilized to compare a score to the rest of the scores in a set of scores. It tells us the percentage of scores equal or below a particular scores.

\(P = \frac{R}{N+1} (100)\)

where, R is the rank and N is the score.

Here,

Lisa's rank = 250 - 26 = 224, N = 250

So, her percentile rank will be,

\(P = \frac{224}{250+1}(100) = 89.24\\ P = 89%\)

P = 89%

210=

that makes the answer 205

Answer:

205 meters

Step-by-step explanation:

The cliff is 350m, and the rescue helicopter is 65m above the top of the cliff.

This means that the helicopter is 415 meters above the bottom of the cliff.

The boy is 210m above the bottom of the cliff.

So, you have to subtract 210 from 415 to get 205.

Therefore, you have to lower the rescue 205m to reach the boy.

The derivative of the function f(x) = 3 ln(x) is f'(x) = 3/x. The domain of f(x) consists of positive real numbers, excluding zero, as the natural logarithm is only defined for positive values. Thus, the domain of f(x) is (0, +∞) in interval notation.

To differentiate f(x) = 3 ln(x), we can use the derivative rules. The derivative of ln(x) is 1/x, and when multiplied by the constant 3, we get f'(x) = 3/x. This derivative represents the instantaneous rate of change of f(x) with respect to x at any given point.

The domain of f(x) is the set of values for x that produce meaningful output for the function.

In this case, the natural logarithm function ln(x) is only defined for positive values of x.

Therefore, the domain of f(x) consists of positive real numbers. However, it is important to note that the value x = 0 is not included in the domain, as the natural logarithm is undefined at x = 0.

Therefore, the domain of f(x) can be expressed as (0, +∞) in interval notation, indicating that it includes all positive real numbers except zero.

By complex and real number properties, the resulting electric resistance is equal to R' = 47 / 270 + i 4 / 45 ohms.

Complex numbers are numbers of the form z = a + i b, where a, b are real numbers. The first component is the real component and the second one is the complex one. In this problem we find the case of a combination of two electric resistances described by two complex numbers. This expression must be simplified by means of real number and complex number properties:

R' = 1 / R₁ + 1 / R₂

If we know that R₁ = 4 + i 6 and R₂ = 2 - i 4, then the resulting electric resistance is:

1 / (4 + i 6) + 1 / (2 - i 4)

(4 - i 6) / [(4 + i 6) · (4 - i 6)] + (2 + i 4) / [(2 - i 4) · (2 + i 4)]

(4 - i 6) / (16 - i² 36) + (2 + i 4) / (4 - i² 16)

(4 - i 6) / (16 + 36) + (2 + i 4) / (4 + 16)

Answer:

The equation of the line is;

3y = 2x-8

Step-by-step explanation:

Firstly, we need the to get the slope of the given line

To do this, we will write the equation of the line in the standard form

the standard form

is;

y = mx + b

where m is the slope and b is the y-intercept

y -4 = 2/3(x-3)

y -4 = 2x/3 - 2

y = 2x/3 -2 + 4

y = 2x/3 + 2

with respect to the given equation, the slope of the line is 2/3

Mathematically, when two lines are parallel, the slopes of the line are equal

So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)

so;

y = 2x/3 + b

So substitute the values of (1,-2)

1 for x and -2 for y

-2 = 2/3(1) + b

-2 = 2/3 + b

b = -2 - 2/3

b = (-6-2)/3 = -8/3

So the equation of that line is;

y = 2/3x - 8/3

Multiply through by 3

3y = 2x - 8
