We got the mean value 4.167 and **standard **deviation 19.56.

In statistics, a mean value is the average value of all the available data. And it can be determined by adding all the data by dividing the amount of data.

A standard deviation is an **estimation **that implies how far each available data apart from the mean value.

we are given, 4% of the population has a genetic mutation

Total people in the group =600

Now, total number of people who have genetic mutation = (4/100) ×600

= 24

the number of randomly selected people =100= X

Mean = Number of selected people/ people who have mutation

Mean = X/n = 100/24 = 4.167

the standard deviation = √∑(X-mean) ²/n

= √∑(selected people - mean) ²/ mutation number

=√(100-4.167) ²/24

standard deviation = 19.56

How do I solve this?

9514 1404 393

**Answer:**

b=-9

intersection point (3, -3)

**Step-by-step explanation:**

There are a couple of ways to do this. The method that does not involve calculus is to set the two equations equal and find 'b' such that there is exactly one solution.

x^2 -4x = y = 2x +b

In standard form, this is ...

x^2 -6x -b = 0 . . . . . . . we call this the "combined quadratic"

This will have one solution when the discriminant is zero. You may recall that the discriminant of quadratic ax^2 +bx +c is d = (b^2-4ac). We want ...

d = (-6)^2 -4(1)(-b) = 0

36 +4b = 0 . . . . . simplify

b = -36/4 = -9 . . . solve for b

Then the linear equation is ...

** y = 2x -9**

__

If the discriminant is zero, the solution to the "combined quadratic" is ...

x = -b/(2a) . . . . . . . . with a, b, c from the quadratic form (not y-intercept)

x = -(-6)/(2(1)) = 3

And the point of intersection of the line and the parabola is ...

y = 2(3) -9 = -3 ⇒ **(x, y) = (3, -3)**

__

The graph is attached.

I need to know how to solve for this.

9514 1404 393

**Answer:**

use the rules of exponents

**Step-by-step explanation:**

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

(a^b)^c = a^(bc)

(ab)^c = (a^c)(b^c)

__

Applying these to the left-side expression, we can simplify it so it looks like the right side expression.

[tex]\dfrac{(12x^5)(2x^7)}{(2x^2)^3}=\dfrac{12\cdot2x^{5+7}}{2^3x^{2\cdot3}}=\dfrac{24x^{12}}{8x^6}\\\\=3x^{12-6}=\boxed{3x^6}[/tex]

Which key features of the graph of two parallel lines are the same and which as different?

The two lines in the graph below are parallel lines: they will never intersect. Notice that they have exactly the same steepness which means their slopes are identical. The only difference between the two lines is the y-intercept. If we shifted one line vertically toward the y-intercept of the other, they would become the same line.

Eli has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.

He buys a new bicycle for $356.89.

He buys 2 bicycle reflectors for $16.70 each and a pair of bike gloves for $27.47.

He plans to spend some or all of the money he has left to buy new biking outfits for $74.08 each.

Write and solve an inequality which can be used to determine oo, the number of outfits Eli can purchase while staying within his budget.

Answer:

He can buy 3 outfits

Step-by-step explanation:

Total: $640

New Bicycle: $356.89

Reflector(2)=$16.70(each)

Gloves:$27.47

First, we calculate the amount left.

Amount=total - (new bicycle + reflector * 2 + gloves)

Amount=$640 - ($356.89 + $16.70 * 2 + $27.47)

Amount=$640 - ($356.89 + $33.40 + $27.47)

Amount=$640 - $417.76

Amount=$222.24

An outfit costs $74.08 and he plans to buy x outfits.

The inequality is as follows:

$74.08x <_(less than or equal to) $222.24

The amount spent on outfits cannot exceed $222.24.

Divide both sides by $74.08.

$74.08x <_ $222.24

/$74.08 /$74.08

X <_ 3

To stay within budget, Eli can buy exactly 3 outfits on top of everything else.

Amber coaches soccer and volleyball. She coaches both sports for a total of 10 hours each day. The soccer practice lasts 1 hour more than twice as long as the volleyball practice. Part A: Write a system of equations to model the situation. Use v for the number of hours Amber coaches volleyball in a day and s for the number of hours she coaches soccer. ( Part B: How many hours each day does Amber spend coaching each sport? Show your work. ( Will Mark Brainliest. Only answer if your 100% sure. This is very important).

**Step-by-step explanation:**

part a: Total is 10 hours

soccer: 2v + 1

volleyball: v

part b: 10 = 2v + 1

-2v = -10 +1

-2v = -9

v = -9 ÷ -2

v = 4.5

volleyball is 4.5 hours

if soccer is one hour longer than volleyball then soccer is 5.5 hours

4.5 + 5.5 is a total of 10 hours :)

How to find the smallest integer k such that 60k is a perfect square

9514 1404 393

**Answer:**

k = 15

**Step-by-step explanation:**

Look for the missing factors that make all of the factors of 60k be squares.

60 = 2² × 3 × 5

The factors 3 and 5 each have an odd exponent (1), so those two factors must be part of k.

60k = 2² × 3 × 5 × k

is a perfect square when ...

3 × 5 = **k = 15**

For **k = 15**, 60k = 900 = 30²
