Al considerar 52 m como la distancia entre dos puntos situados realmente 53.06 m

Answer:

0.0478

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 135 mm

μ is the population mean = 130 mm

σ is the population standard deviation.

We are given variance = 9

Standard deviation = √variance = √9 = 3

Hence

z = 135 - 130/3

z = 1.66667

Probability value from Z-Table:

P(x<135) = 0.95221

P(x>135) = 1 - P(x<135) = 0.04779

Approximately to 4decimal places = 0.0478

Answer:

-70 so A

Step-by-step explanation:

Answer:

D) 70

Step-by-step explanation:

Here is the correct mathematical way of find a distance between two points on the number line.

Take the absolute value of the difference of their coordinates.

If the points on a number line correspond to coordinates a and b, the distance between the points is

|a - b|

Your problem:

|a - b| = |-57 - 13| = |-70| = 70

The distance is 70.

Answer: D) 70

I asked some friends and they told me the above

Answer:

14.3

Step-by-step explanation:

Remark

Make a rough sketch of the triangle.

Make F the right angle

Make <D = 66

E is the other angle.

Givens

EF = 32

<F = 90

<D = 66

Equation

Tan(D) = EF/FD

Solution

Tan(66) = 32/FD                  Multiply both sides by FD

FD*Tan(66) = 32            

Tan(66) = 2.246

2.246 * FD = 32                  Divide by 2.2246

FD = 32/2.246

FD = 14.25

FD = 14.3

Answer:

The correct expression for this would be:

4g + 2c = 300

Step-by-step explanation:

Since the console costs 300 for buying 4 games and 2 controllers, let's represent 4 games with 4g and 2 controllers with 2c.

This means 4g and 2c gives 300. Mathematical, this is written as

4g + 2c = 300

Answer:

29

Step-by-step explanation:

I subtracted 65 from 36 since the question only gave me 2 numbers and a variable to use.

Step-by-step explanation:

c = 65 - 36

c = 29

C is 29 that is the answer

Answer:

I think the answer is 12 = 100

Step-by-step explanation:

since 9 = 80 and that is the same for 11, if you do 180 - 80 = 100 which would be the answer for 10 and 12. Thus 12 = 100 based on the info given.

Answer:

To calculate the perimeter of a circle we have this formula:

[tex]P = 2\pi r[/tex]

And, if we're going to calculate for a semicircle, we should divide it by 2

We should also take into account the diameter, as, if it's a semicircle, we also have to add the base of it, which will have the diameter length

Knowing this, we can see the formula to calculate this specific perimeter

[tex]\frac{2\pi r}{2} + 2r[/tex]

Now, we can replace r by 22:

[tex]\frac{2\pi *22}{2} + 2*22 \approx 113.12[/tex]

So the perimeter is approximately 113.12 cm

Given :

Gary Sanchez struck out 112 times in 350 at bats.

To Find :

Percentage of his at-bats were strike outs.

Solution :

We know, percentage hits is given by :

[tex]Percentage = \dfrac{\text{Number of time bats were strike out}}{\text{Total number of bats}}\times 100 \ \%[/tex]

Putting all given values in above equation, we get :

[tex]Percentage = \dfrac{112}{350}\times 100\ \%\\\\Percentage = 32\ \%[/tex]

Hence, this is the required solution.

Step 2: Find Radius r

Answer:

0.9

Step-by-step explanation:

4(pi)r²= 10.1

4 × (pi) × r² = 10.1

r² = 10.1 / (4×(pi) )

r² = 0.8037

Therefore, r= 0.8965

Answer:

3.5 cm

Step-by-step explanation:

The computation of the approximate length of minor arc JH is as follows

As in the attached picture we can see that circle M is shown also the minor arc measures 25 degrees

Now the circle length is

= π × 16

= 50.26 cm.

Now this length would be proportional to 360 degrees

Let us assume the minor length arc JH be x

So, the equation would be

50.26 cm ÷  x cm = 360° ÷ 25°

x = 50.26 × 25 ÷ 360

x = 3.5 cm

Answer:

A. 3.5 cm

Step-by-step explanation:

In the picture attached, circle M is shown.

From the picture, minor arc JH measures 25°.

The length of the circle is π*Diameter = π*16 = 50.26 cm. This length is proportional to 360°. To find the length of minor arc JH, we have to use the next proportion:

50.26 cm / x cm = 360° / 25°

x = 50.26*25/360

x = 3.5 cm

Answer:

[tex]\mathbf{a}\cdot \mathbf{b}=-3[/tex]

Step-by-step explanation:

The dot product of vectors.

Given two vectors a and b in their rectangular form:

[tex]\mathbf{a}= a_x\mathbf{i}+a_y\mathbf{j}[/tex]

[tex]\mathbf{b}= b_x\mathbf{i}+b_y\mathbf{j}[/tex]

The dot product of the vectors is a scalar with value:

[tex]\mathbf{a}\cdot \mathbf{b}=a_x.a_y+b_x.b_y[/tex]

The given vectors are:

[tex]\mathbf{u}= -5\mathbf{i}+3\mathbf{j}[/tex]

[tex]\mathbf{v}= 3\mathbf{i}+4\mathbf{j}[/tex]

Calculating the dot product:

[tex]\mathbf{a}\cdot \mathbf{b}=(-5)(3)+(3)(4)=-15+12=-3[/tex]

[tex]\mathbf{a}\cdot \mathbf{b}=-3[/tex]

Answer:

r=√(3v)/(xh)

Step-by-step explanation:

the volume of a cone is given as

v= 1/3 xr^2 h. Then we need the radius, r, of the cone

v= 1/3 xr^2 h

Let us cross multiply we have

3v= xr^2h

Make r^2 subject of the formula we have

r^2= 3v/xh

Find the square root of bother sides we have

r=√(3v)/(xh)

the radius, r, of the cone can be expressed as r=√(3v)/(xh)

Answer:

Answer:

C

Step-by-step explanation:

The general form of a polynomial expression is

[tex]a_{n}[/tex][tex]x^{n}[/tex] + [tex]a_{n-1}[/tex][tex]x^{n-1}[/tex] + [tex]a_{n-2}[/tex][tex]x^{n-2}[/tex] + ............ + a₁[tex]x^{1}[/tex] + a₀

For the given polynomial the [tex]x^{n}[/tex] term is - [tex]x^{13}[/tex] , that is n = 13 , thus

n - 7 = 6 , that is the [tex]x^{6}[/tex] term

with [tex]a_{n-7}[/tex] being its coefficient

Since there is no [tex]x^{6}[/tex] term, then its coefficient is zero, that is

[tex]a_{n-7}[/tex] = 0 → C

Answer:

$109.96

Step-by-step explanation:

Using the data from the table we need to add all of the transaction amounts together in order to calculate the final balance amount at the end of the first month since all of the transactions listed in the table are from the same month. (negative values cancel out the addition and instead subtract from the total)

100 + (-12.25) + 25.82 + 14.95 + (-18.56) = 109.96

Assuming that the initial account balance at the beginning of the month was $0 then the account balance at the end of the month would be $109.96

Answer:

x = 2

Step-by-step explanation:

It is given that,

U is the midpoint of TV.

TU = x² + 2x – 2

UV = -x+8

We need to find a positive value of x.

For midpoint,

TU  = UV

Putting values,

x² + 2x – 2 = -x+8

or

x² + 2x – 2+ x - 8= 0

x² +3x-10 = 0

x² +5x - 2x -10 = 0

x(x+5) -2(x+5) = 0

(x-2) (x+5) = 0

x = +2 and x = -5

Hence, the positive value of x is 2.
