The value of c for a standard normal distribution, P(z < c) = 0. 3387 is -0.41.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ)/σ

Where x is the raw score, μ is the mean and σ is the standard deviation.

Given that P(z < c) = 0. 3387; hence:

From the normal distribution table, c = -0.41

The value of c for a standard normal distribution, P(z < c) = 0. 3387 is -0.41.

Step-by-step explanation:

First of all the equation is subtracttion since they used to word *difference* which indicates subtract. To find the different between how much Anna at and how much she gave her brother we would subtract 5/8 by 3/8.

to solve this equation ( 5/8 - 3/8 ) the denominator of both fractions have yo be the same and that is true for this equation. Then you would subtract the numerators and keep the denominator the same. So the answer is 2/8

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

(x, y) ==> (2, 2)

Point-slope forms:

6x + 2y = 16

-6x          -6x

2y = -6x + 16

/2        /2

y = -3x + 8

2x - y = 2

-2x      -2x

-1y = -2x + 2

/-1       -1

y = 2x - 2

Answer:

3 people

$9.5 left over

Step-by-step explanation:

pp = 18 + 22.75

pp = 40.75

total people who can go = 131.75/pp

tp = 131.75/pp

tp = 3 remainder $9.5

(this is if they all arrive in individual cars)

The number of people that can go to the amusement park are 5 .

First, we need to find the amount left after deducting parking charges. Then the remaining amount can be divided by the price of one ticket to find out how many persons can buy the ticket from the same amount.

Thus, 5 number of persons can go to the amusement park.

Answer:

7.5

Step-by-step explanation:

Ok so this is how I got it:

Since we know the lengths of sides NO, MN, and JK, but we don't know the length of KL, we can use what we know.

To get from MN to JK, we multiply MN (2) by 1.5 to get 3. So you can go the same thing to get from NO to KL.

Just go ahead and multiply 5 by 1.5

5 × 1.5 = 7.5

Hope this helps!

Answer:

KL = 7.5

Step-by-step explanation:

MN : JK = NO : KL

⇒ 2 : 3 = 5 : KL

[tex]\implies \dfrac23=\dfrac{5}{KL}[/tex]

⇒ 2 · KL = 5 · 3

⇒ 2(KL) = 15

⇒ KL = 15 ÷ 2

⇒ KL = 7.5

The distance minute hand tracked from 2 to 6 is  5.23 inches.

A clock can be thought of as a circle having 12 steps and we know that circle is 360°,

So, the measure of each integer step of a clock is 30°or π/12 rad.

We know the circumference of a circle is 2πr.

From 2 to 6 the minute hand rotated (4×30°) = 120° = 2π/3 rad.

We know arc length(S) = r×Ф.

∴ The distance minute hand tracked is = (2.5)×(2π)/3 inches.

= 5.23 inches.

Given that the parent function, y = x², has a leading coefficient of 1, the

following are the comparisons of the equations with the parent functions;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The parent function is y = x²

The leading coefficient of the parent function = 1

The steepness of a quadratic equation is given by the value of the

leading coefficient.

When the leading coefficient is larger than 1, we have;

The function is steeper than y = x²

When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;

The function is less steep than y = x²

Which gives;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]
