A standard normal distribution's characteristics are its mean is equal to 0 and the standard deviation is 1. Thus, the variance is equal to 1.

A normal distribution that has a mean value of 0 and a standard deviation or a variance of 1 is said to be a standard normal distribution.

I.e., μ = 0 and σ² = 1

This is also called z-distribution.

A standard normal distribution has μ = 0 and σ² = 1.

So, the probability of a normal random variable is calculated by using a z-score.

The z-score value is calculated by the formula

z = (X - μ)/σ

Where mean (μ) and standard deviation (σ) for the variable X

By using the standard normal distribution tables with the z-score and probabilities, the required values are calculated.

So, we can conclude that the major characteristics of a standard normal distribution are mean = 0 and variance = 1.

The dot isn’t shaded so > or <

From -55, it’s showing small than

From -49, it’s showing greater than

x < -55 or x > -49

Answer:  x < -55 or x > -49

Step-by-step explanation:

x < -55 or x > -49

They both start with an opened circle, and also these two opened circle dots do not connect to each other. On the left side, the number is going from -55 to the smaller side, -57 or less, so we can say that x is smaller than -55. On the right side, the number goes from -49 to the bigger number, we can say that x is greater than -49.

It is given that you have invested $50 a month in an annuity that earns 48% APR compounded monthly. We can conclude that after 2 years you will have $1954.13 in your account.

To solve this we are going to use the formula for the future value of an ordinary annuity:

\(P[(\frac{(1+(r/n)^{nt}-1)}{(r/n)}]\)

where

FV is the future value

P is the periodic payment

r is the interest rate in decimal form

n is the number of times the interest is compounded per year

t is the number of years

It is given that you have invested $50 a month in an annuity that earns 48% APR compounded monthly. we need to find how much money you have in this account after 2 years.

Since the interest is compounded monthly, it is compounded 12 times per year; therefore,

r = 48% = 0.48

n = 12

Let's put the values in our formula:

\(P[(\frac{(1+(r/n)^{nt}-1)}{(r/n)}]\\\\50[(\frac{(1+(0.48/12)^{12\times 3}-1)}{(0.48/3)}]\\\\$1954.13\)

Thus, We can conclude that after 2 years you will have $1954.13 in your account.

The probability that the student got an 'A' given they are male is approximately 0.12 or 12%.

To find the probability that a student got an 'A' given they are male, we need to use Bayes' theorem:

P(A | Male) = P(Male | A) × P(A) / P(Male)

We can find the values of the terms in the formula using the information given in the table:

P(Male) = (25/54) = 0.46 (the proportion of all students who are male)

P(A) = (17/54) = 0.31 (the proportion of all students who got an 'A')

P(Male | A) = (3/17) = 0.18 (the proportion of all students who are male and got an 'A')

Therefore, plugging these values into the formula:

P(A | Male) = 0.18 × 0.31 / 0.46

P(A | Male) ≈ 0.12

So the probability that the student got an 'A' given they are male is approximately 0.12 or 12%.

Maria live 96 miles from the Sun Dome.

Let the distance between Orlando to Sun Dome = x

Distance she covered by driving = 16 miles

Distance she covered by bus = 3x/4

Distance she covered by cab = x/12

Therefore, 16 + 3x/4 + x/12 = x

                 (192 + 9x + x)/12 = x

                            192 + 10x = 12x

                             12x - 10x = 192

                                       2x = 192

                                         x = 192/2

                                         x = 96

Answer: (0,3)

x=0 ; y=3

Step-by-step explanation:

To solve the system of equations:

2x + 4y = 12

3x + y = 3

We can use the method of substitution or elimination. Here we will use the substitution method:

From Equation 2, we can isolate y:

y = 3 - 3x

We can substitute this expression for y into Equation 1:

2x + 4(3 - 3x) = 12

Simplifying and solving for x:

2x + 12 - 12x = 12

-10x = 0

x = 0

Now that we have found the value of x, we can substitute it back into either Equation 1 or Equation 2 to solve for y. Here we will use Equation 2:

3(0) + y = 3

y = 3

Therefore, the solution to the system of equations is (x, y) = (0, 3).

This means that the point (0, 3) is the intersection point of the two lines represented by the given equations. To verify this, we can substitute the values of x and y into both equations and see if they are true.

The ordered pair solutions for the system of equations are (-2, 5) and (1, 2).

To determine if an ordered pair is a solution to two systems of equations, substitute the values ​​of the variables into each equation. If an ordered pair makes both equations true, it is the solution of the system. 

To find the ordered pair solutions for the system of equations, we need to solve the two equations simultaneously.

f(x) = x² + 1 ...(1)

f(x) = -x + 3 ...(2)

Setting the two equations equal to each other, we get:

x² + 1 = -x + 3

Rearranging this equation, we get:

x² + x - 2 = 0

Factoring this quadratic equation, we get:

(x + 2)(x - 1) = 0

Therefore, the solutions for x are x = -2 and x = 1.

Substituting these values of x into either equation (1) or (2), we get:

For x = -2: f(-2) = (-2)² + 1 = 5, and f(-2) = -(-2) + 3 = 5.

For x = 1: f(1) = 1² + 1 = 2, and f(1) = -1 + 3 = 2.

Therefore, the ordered pair solutions for the system of equations are (-2, 5) and (1, 2).

Hi there!

To find the Trigonometric Equation, we have to isolate sin, cos, tan, etc. We are also given the interval [0,2π).

First Question

What we have to do is to isolate cos first.

\( \displaystyle \large{ cos \theta = - \frac{1}{2} }\)

Then find the reference angle. As we know cos(π/3) equals 1/2. Therefore π/3 is our reference angle.

Since we know that cos is negative in Q2 and Q3. We will be using π + (ref. angle) for Q3. and π - (ref. angle) for Q2.

Find Q2

\( \displaystyle \large{ \pi - \frac{ \pi}{3} = \frac{3 \pi}{3} - \frac{ \pi}{3} } \\ \displaystyle \large \boxed{ \frac{2 \pi}{3} }\)

Find Q3

\( \displaystyle \large{ \pi + \frac{ \pi}{3} = \frac{3 \pi}{3} + \frac{ \pi}{3} } \\ \displaystyle \large \boxed{ \frac{4 \pi}{3} }\)

Both values are apart of the interval. Hence,

\( \displaystyle \large \boxed{ \theta = \frac{2 \pi}{3} , \frac{4 \pi}{3} }\)

Second Question

Isolate sin(4 theta).

\( \displaystyle \large{sin 4 \theta = - \frac{1}{ \sqrt{2} } }\)

Rationalize the denominator.

\( \displaystyle \large{sin4 \theta = - \frac{ \sqrt{2} }{2} }\)

The problem here is 4 beside theta. What we are going to do is to expand the interval.

\( \displaystyle \large{0 \leqslant \theta < 2 \pi}\)

Multiply whole by 4.

\( \displaystyle \large{0 \times 4 \leqslant \theta \times 4 < 2 \pi \times 4} \\ \displaystyle \large \boxed{0 \leqslant 4 \theta < 8 \pi}\)

Then find the reference angle.

We know that sin(π/4) = √2/2. Hence π/4 is our reference angle.

sin is negative in Q3 and Q4. We use π + (ref. angle) for Q3 and 2π - (ref. angle for Q4.)

Find Q3

\( \displaystyle \large{ \pi + \frac{ \pi}{4} = \frac{ 4 \pi}{4} + \frac{ \pi}{4} } \\ \displaystyle \large \boxed{ \frac{5 \pi}{4} }\)

Find Q4

\( \displaystyle \large{2 \pi - \frac{ \pi}{4} = \frac{8 \pi}{4} - \frac{ \pi}{4} } \\ \displaystyle \large \boxed{ \frac{7 \pi}{4} }\)

Both values are in [0,2π). However, we exceed our interval to < 8π.

We will be using these following:-

\( \displaystyle \large{ \theta + 2 \pi k = \theta \: \: \: \: \: \sf{(k \: \: is \: \: integer)}}\)

Hence:-

For Q3

\( \displaystyle \large{ \frac{5 \pi}{4} + 2 \pi = \frac{13 \pi}{4} } \\ \displaystyle \large{ \frac{5 \pi}{4} + 4\pi = \frac{21 \pi}{4} } \\ \displaystyle \large{ \frac{5 \pi}{4} + 6\pi = \frac{29 \pi}{4} }\)

We cannot use any further k-values (or k cannot be 4 or higher) because it'd be +8π and not in the interval.

For Q4

\( \displaystyle \large{ \frac{ 7 \pi}{4} + 2 \pi = \frac{15 \pi}{4} } \\ \displaystyle \large{ \frac{ 7 \pi}{4} + 4 \pi = \frac{23\pi}{4} } \\ \displaystyle \large{ \frac{ 7 \pi}{4} + 6 \pi = \frac{31 \pi}{4} }\)

Therefore:-

\( \displaystyle \large{4 \theta = \frac{5 \pi}{4} , \frac{7 \pi}{4} , \frac{13\pi}{4} , \frac{21\pi}{4} , \frac{29\pi}{4}, \frac{15 \pi}{4} , \frac{23\pi}{4} , \frac{31\pi}{4} }\)

Then we divide all these values by 4.

\( \displaystyle \large \boxed{\theta = \frac{5 \pi}{16} , \frac{7 \pi}{16} , \frac{13\pi}{16} , \frac{21\pi}{16} , \frac{29\pi}{16}, \frac{15 \pi}{16} , \frac{23\pi}{16} , \frac{31\pi}{16} }\)
