Answer is below

Step-by-step explanation:

16ef³÷8e²f=[tex]\frac{2f^{2}}{e}[/tex]

[tex]\frac{24m^{2} n^{3} }{2mn} = 12m n^{2}[/tex]

[tex]\frac{2k^{3} +k}{4k} =\frac{1}{2} k^{2} +\frac{1}{4}[/tex]

Answer:

[tex]Mean = 0.36[/tex]

[tex]SD = 0.5817[/tex]

[tex]P(x=3) = 0.003588[/tex]

Step-by-step explanation:

Given

Let

A = Event of being a universal donor.

So:

[tex]P(A) = 0.06[/tex]

[tex]n = 6[/tex]

Solving (a): Mean and Standard deviation.

The mean is:

[tex]Mean = np[/tex]

[tex]Mean = 6 * 0.06[/tex]

[tex]Mean = 0.36[/tex]

The standard deviation is:

[tex]SD = \sqrt{np(1-p)}[/tex]

[tex]SD = \sqrt{6*0.06*(1-0.06)}[/tex]

[tex]SD = \sqrt{0.3384}[/tex]

[tex]SD = 0.5817[/tex]

Solving (b): P(x = 3)

The event is a binomial event an dthe probability is calculated as:

[tex]P(x) = ^nC_x * p^x * (1-p)^{n-x}[/tex]

So, we have:

[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}[/tex]

[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3[/tex]

[tex]P(x=3) = 20 * 0.06^3 * (1-0.06)^3[/tex]

[tex]P(x=3) = 0.003588[/tex]

Given:

[tex]x=-\dfrac{8}{9},\ y=-\dfrac{3}{5}[/tex]

To verify:

[tex]x+y=y+x[/tex]

Solution:

We need to verify,

[tex]x+y=y+x[/tex]

Taking left hand side, we get

[tex]LHS=x+y[/tex]

After substituting the values, we get

[tex]LHS=-\dfrac{8}{9}+\left(-\dfrac{3}{5}\right)[/tex]

[tex]LHS=-\dfrac{8}{9}-\dfrac{3}{5}[/tex]

[tex]LHS=\dfrac{-40-27}{45}[/tex]

[tex]LHS=\dfrac{-67}{45}[/tex]

Now,

Taking right hand side, we get

[tex]RHS=y+x[/tex]

After substituting the values, we get

[tex]RHS=-\dfrac{3}{5}+\left(-\dfrac{8}{9}\right)[/tex]

[tex]RHS=-\dfrac{3}{5}-\dfrac{8}{9}[/tex]

[tex]RHS=\dfrac{-27-40}{45}[/tex]

[tex]RHS=\dfrac{-67}{45}[/tex]

Clearly,

[tex]LHS=RHS[/tex]

Hence verified.

Answer:

y = 3x + 1

Step-by-step explanation:

the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y

m = -3/-1 = 3

two parallel lines have the same slope, so also the line that we are a searching has m=3

now we can use this formula

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point

y-(-2) = 3 (x-(-1)

y+2 = 3x + 3

y = 3x + 3-2

y = 3x + 1

Answer:

Song =$1.50 Album =$12.99

Step-by-step explanation:

Lets assume Individual songs = x

albums=y

6x + y = 21.99-------- y= 21.99- 6x

4x + 3y= 44.97

Replace y in the second equation

4x+ 3(21.99-6x) = 44.97

4x +65.97- 18x = 44.97

14x= 21

x = 1.50

y= 21.99- (6*1.50)

= 12.99

Answer:

Step-by-step explanation:

Raising her rate by 15% is equivalent to adding 15% of what she charged before to the original price.

Answer:

24 x 25/100 = 6

of means multiplication so you are multiplying the percent to the regular price. Always consider cent as a hundred and a percent out of 100 in fractions.

Answer:

18 dollars

Step-by-step explanation:

half of 24 is 12 and half of that is 6 so 24-6=18 :)

Answer: $300 per month (assumed)

Step-by-step explanation:

As figures are lacking in this question, I will use assumed figures and you can use it as a reference.

Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.

If she reduces this time to half, the amount of hours she begins to tutor is:

= 60 hours / 2

= 30 hours

At a rate of $10 an hour, her monthly income becomes:

= 10 * 30

= $300 per month

Answer:

No Problem

Step-by-step explanation:

Answer:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Step-by-step explanation:

Surface area means, basically the outside of the shape, faces is a fancy way schools use to say sides, for example a cuboid, these look like rectangles but 3D, It has 6 "faces" or sides. And it also has 12 edges. With my school, they usually fill the 3D shapes with cubes to have a way to estimate the size, or they might write it on the sides like 2D shapes. Prisim means a 3D shape that has 2 faces that are the exact same, like a 2D rectangle. Which is a look-alike to the cuboid. SA=2lw+2lh+2hw might look , difficult but it means SA=surface answer, 2LW means length with, 2LH means length hight, and 2HW means hight width.

Answer:

35%

Step-by-step explanation:

Given data

Initial price= $80

Final price= $52

% decrease= initial-final/initial*100

% decrease= 80-52/80*100

% decrease= 28/80*100

% decrease=0.35*100

= 35%

Hence the decrease is 35%

Answer:

Step-by-step explanation:

Answer:

The answer is 4 cm

Step-by-step explanation:

Volume of the triangular prism = 544 m³

height of the prism (h) = 17 m

Also

Volume of the prism = Area of base * height

544 = Area of base * 17

Area of base = 544 / 17

Area of base = 32 m²

Now

Base of the triangle (b) = 16 m

Area of the triangle = 32 m³

height (h) = ?

We know

Area of triangle = 1/2 * b * h

32 = 1/2 * 16 * height

32 * 2 / 16 = height

height of the triangle = 4 m

Given:

The function is:

[tex]y=-(2x-4)(x-2)[/tex]

To find:

The x-intercepts and zeros of the given function.

Solution:

We have,

[tex]y=-(2x-4)(x-2)[/tex]

For x-intercepts, [tex]y=0[/tex].

[tex]-(2x-4)(x-2)=0[/tex]

[tex](2x-4)(x-2)=0[/tex]

Using zero product property, we get

[tex](2x-4)=0[/tex] and [tex](x-2)=0[/tex]

[tex]2x=4[/tex] and [tex]x=2[/tex]

[tex]x=\dfrac{4}{2}[/tex] and [tex]x=2[/tex]

[tex]x=2[/tex] and [tex]x=2[/tex]

The given function has two equal zeroes or x-intercept, i.e., [tex]x=2[/tex].

Therefore, the zeroes are 2 and 2.

Note: All options are incorrect.

The sum of the parts 11/7 and 12/5 of pizza is 139/35.

It is given that the parts of pizza are:

[tex]1. 11/7\\2. 12/5\\[/tex]

It is required to find sum of the parts of pizza.

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called denominator.
