Dividing this by the 35 m traveled, we get the bike turned [tex]\frac{35}{0.942} \approx 37.2[/tex]

Answer:

y = - 2x + 12

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (6, 0 ) and (x₂, y₂ ) = (- 1, 14 )

m = [tex]\frac{14-0}{-1-6}[/tex] = [tex]\frac{14}{-7}[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 0 )

0 = - 12 + c ⇒ c = 0 + 12 = 12

y = - 2x + 12 ← equation of line

The standard deviation for the number of people with the genetic mutation in such groups is 3.1305.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Let X be the number of people with genetic mutation is a group of 500,

The formula of standard deviation is given as

[tex]SD=\sqrt{n*p(1-p)} \\SD=\sqrt{500*0.02*0.98} \\SD=3.1305[/tex]

The required probability would be 0.146 that it takes 3 shots for the marksman to hit the long-range target.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A marksman has a probability of 0.322 for hitting a certain long-range target which is given in the question.

It takes the marksman 3 shots to hit the long-range target = P(E)

Required probability = P(E)

Here no long-range hits in the 1st two shots = (E₁)

And a long-range hit on the 3rd shot = (E₂)

P(E) = P( (E₁) and (E₂))

P(E) = (1 - 0.288) (1-0.288)(0.288)

P(E) = 0.146

Therefore, the required probability would be 0.146 that it takes 3 shots for the marksman to hit the long-range target.

Answer C
This statement is  not true

Step-by-step explanation:

Logarithms result in real values only for positive values of the argument i.e. log(x) results in a real value only for x > 0 So A is correct

Range is set of all real numbers -∞ < x < ∞ So B is correct

D is also correct. At x = 0, log is not defined

Only C is incorrect. If 0 < a < 1 the graph actually shows a downward trend ie logarithmic decline instead of growth

Based on the compound interest rate on the bank account and the number of months that Cameron invested the amount for, the money in his account will be £4,777.81

The amount that will be in the account after 2 years and 7 months can be found by the formula:

= Amount invested x ( 1 + periodic rate) ^ number of periods

The number of months (periods) is:

= 2 years + 7 months

= 31 months

The periodic rate is:

= 5% / 12 months a year

= 5/12%

The amount that Cameron will have in his bank account after 2 years and 7 months will be:

= 4,200 x (1 + 5/12%)³¹

Answer: You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values. If those ratios are, all the same, the table shows a proportional relationship.

     A vector space, also known as a linear space, is a set whose elements, frequently termed vectors, can be added to and multiplied ("scaled") by figures known as scalars. Real numbers make up scalars most of the time, but they can also be complex numbers or, more broadly, components of any field.

        Every vector space has a scalar field F at its foundation (to be specified shortly).

Real and complex numbers are two examples of scalar fields.

Real numbers R:

C: Complex numbers.

We only utilize these fields in this context.

Definition : A group of objects in a vector space V have a (vector)

scalar multiplication defined as closed under both addition and multiplication

also satisfying the following axioms:

I For any x V and, F, ( + )x = x + x

(ii) α(βx)=(αβ)x

(iii) For all x, y V, x + y = y + x

(iv) For any x, y, and z > V, x + (y + z)=(x + y) + z.

(v) α(x + y) = αx + αy

(vi) O V z 0 + x = x, where 0 is commonly referred to as the origin

    Since V cannot be left using vector addition or scalar multiplication, the "closed" criterion described above states that for any, F and x, y V x + y V. Additionally, the "+" is in the field when we write for, F and x V ( + )x, but it is in the vector space when we write for x + y for x, y V. This symbol has a variety of uses.

(1) R2 is equal to the two-dimensional space (a1, a2) | a1, a2 R.

(2) In an n-dimensional space, Rn = (a1, a2,..., an) | a1, a2,..., an.

An "n-tuple" is (a1, a2,...,an).

(3) C, the field of complex numbers, to C2 and Cn, respectively, to R2 and Rn.

Pn = l n j = 0 ajxj | a0,

The polynomial space of all polynomials of degree n is denoted as Pn = l n j=0 ajxj | a0, a1,...,an R M. Be aware that this covers polynomials of all degrees, not only those with n degrees exactly.

(5) fp = (ai,...) | ai p, |ai| R. Vectors in the form of infinite-tuples of numbers make up this space. To properly designate the field, we would write fp(R) or fp(C).

Trigonometric polynomials TN = F N n=1 a sin nx | a1,...,an R k are included in the list.

Typical vecs in Rn e1 = (1, 0,... , 0)

e2 = (0, 1, 0,... , 0) (0, 1, 0,... , 0)

a) 620° is an angle coterminal to 360°. The reference angle associated with 260° is 260°.

b) The measure of 260° in radian system equals to 13π / 9 radians.

Two angles are coterminal when they share the same initial and terminal sides. Two consecutive coterminal angles have a difference of 360° (2π radians). Then, we can find any angle of a family of coterminal angles by using this formula:

θ' = θ + i · 360°

Where:

a) If we know that θ = 260° and i = 1, then the measure of an example of coterminal angle is:

θ' = 260° + 1 · 360°

θ' = 620°

620° is an angle coterminal to 360°.

The reference angle is the angle whose measure is equal to or greater than 0° and equal to or less than 360°. Thus, the reference angle associated with 260° is 260°.

b) According to radian system, 2π radians are equal to 360°. Thus, the measure of 260° is found by the following simple rule of three:

x = 260° × 2π / 360°

x = 13π / 9 rad

The measure of 260° in radian system equals to 13π / 9 radians.

Step-by-step explanation:  Confirmed correct.

An additional 36 gallons of water will be pumped into the pool past 13 minutes

Constant rate of flow: The definition of a constant rate of flow rate shows how fluid of a certain volume moves through a segment in a specified amount of time. Instead of measuring how quickly a fluid moves from point A to point B, the motion of fluids is examined by figuring out its flow rate. Specifically, how much fluid volume moves from point A to point B in a given amount of time.

Time for which water has been pumped into the pool = 13 minutes

Rate of flow of water = 24 gal/min

So, water pumped in 1.5 minutes = 24*1.5 = 36 gallons

Total water pumped in the pool in 14.5 minutes = 24*14.5 = 348 gallons
