which value is an irrational number? a. 4/19 b. the square root of 200 c. the square root of seven over the square root of seven d. -0.58 repeated

Answer:

irrational number

Step-by-step explanation:

because it has no repeating pattern

The number x = 90.790170  is rational number as it is a finite decimal and can be represented as a fraction.

Given data:

Let the number be represented as x.

Now, the value of x = 90.790170

Rational numbers can be positive, negative, or zero, and they can be written in the form a/b, where a is the numerator and b is the denominator, with b not equal to zero.

The number 90.790170 is a rational number. A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero.

Since 90.790170 is a finite decimal (it doesn't repeat or go on forever), it can be represented as a fraction of two integers.

Hence, 90.790170 is rational.

Left-handedness is _more_______ common than usual among mathematicians and ___more_____ common than usual among artist

The relationship between handedness and mathematical ability is still highly controversial.

While some researchers have claimed that left-handers are gifted in mathematics and strong right-handers perform the worst in mathematical tasks, others have more recently proposed that mixed-handers are the most disadvantaged group.

However, the studies in the field differ with regard to the ages and the gender of the participants, and the type of mathematical ability assessed.

To disentangle these discrepancies, we conducted five studies in several Italian schools (total participants: N = 2,314), involving students of different ages (six to seventeen) and a range of mathematical tasks.

The results show that (a) linear and quadratic functions are insufficient for capturing the link between handedness and mathematical ability; (b) the percentage of variance in mathematics scores explained by handedness was larger than in previous studies.

The last theory drawing a causal link from handedness to mathematical ability through cognition is the hemispheric indecision hypothesis.

Answer:

20

Step-by-step explanation:

The total fare, f, is:

f = 2.25x + 3

We want to solve for x. the number of miles. This is fairly simple if we know f.

48 = 2.25x + 3
48 - 3 = 2.25x + 3 - 3
45 = 2.25x
45/2.25 = 2.25x/2.25

False, Mathematically, an odds ratio equates to a risk ratio, therefore, odds ratios can be interpreted in an exactly same way as risk ratio.

What distinguishes risk from probability?

The fundamental distinction is that the relative risk is a ratio of two probabilities, but the odds ratio is a ratio of two odds (yes, it's that clear). (The risk ratio is another name for the relative risk.)

Used to approximate the relative risk in case-control studies, when the occurrence of diseases are KNOWN

odds of an event = the number of ways an event can occur to the numbers of ways an event cannot occur

odds ratio = P / (1-P)

The point at which Leila should stop to take break is (6.25 , 3.75)

Given P(10 , 3) and R (0 , 4)

The ratio is 3:5

Let the break point be point B.

The formula is : (n(x₁) ₊ m(x₂)/ m₊n , n(y₁) ₊ m(y₂)/ m₊n)

P(10,3) = (x₁ , y₁)

R(0,4) = (x₂ , y₂)

m:n = 3:5

B = (5(10) ₊ 3(0)/3₊5 , 5(3) ₊ 3(4)/3₊5)

By using the concept of dilation, we find that scale factor from A to B is equal to l' / 5, where l' is the length of the shortest side of the quadrilateral B.

Scale factor is a key variable used to dilate lengths and distances by rigid transformations. Then, the length of the shortest side of the quadrilateral B is equal to the product of the scale factor and the length of the shortest side of the quadrilateral A. Mathematically speaking, this kind of rigid transformation is represented by the following formula:

r = l' / l      

Where:

If we know that l = 5, then the length of the shortest side of the quadrilateral B is equal to the following linear equation:

Using translation concepts, the first graph is the correct one.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the function y = |x - 1| is a shift right of 1 unit of the function y = |x|. For the inequality, all the values above the line, including the line, are marked.

The graph of |x - 1| is triangular positive, with vertex at x = 1, hence the first graph is the correct one.

Based on the number of seals that were tagged near Avila Beach, the approximate number of seals near Avila Beach is 44 seals

The number of seals near Avila beach can be said to be x. If it is x, then the formula is:
12 = 27% x ×

27%x = 12

0.27x = 12

Solving for x then gives:

x = 12 / 0.27

x = 44.44

= 44 seals

The total costs are the same when a kayak is rented for 5 hours

How do we determine the hours that both have the same costs?

The hours that both shops have the same cost is determined by equating the total cost in shop A to the total  cost in shop B, in short, we need to first of all , model the total cost in each shop based on the straight-line equation formula shown below since the total cost is made of fixed charge and variable charge

y=a+bx

y=total cost

a=fixed charge for each shop

b=hourly fee

x=number of hours

Shop A:

total cost=8+3x

Shop B:

The hours when the cost of renting the kayaks would be the same is 5 hours.

The total cost of renting a kayak is $23.

The equation that can be used to represent the total cost of renting a kayak is a linear function. A linear equation is an equation whose graph is a straight line. A linear equation increases by a predetermined constant. An example of a linear equation is x + 2.

The form that the equation would be is:

Total cost = rental fee + (hourly fee x number of hours)

Total cost at Shop A = $8 + $3h

Total cost Shop B = $3 + $4h

Where h is the number of hours the kayak was rented.

When the total costs are equal, the two above equations would be equal.

$3 + $4h  =  $8 + $3h

Combine similar terms: $4h - $3h=  $8 - $3

Add similar terms together: h = 5 hours

Total cost = $3 + $4(5)

$3 + $20 = $23

Step-by-step explanation:

Since the angle is greater than 95, y must be greater than x

A linear pair , m∠7 = 58°, m∠6 = 122° are the measurement of each angle.

What is Linear Pair?

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.

Linear Pairs add up to equal 180°.

Step 1: Define

m∠6 + m∠7 = 180°

2m∠6 = 4m∠7 + 12

Step 2: Rewrite systems of equations

I will set m∠6 = x and m∠7 to y

x + y = 180°

2x = 4y + 12

Step 3: Rewrite 2nd equation

2x = 2(2y + 6)

x = 2y + 6

Step 4: Use Substitution

2y + 6 + y = 180

3y + 6 = 180

3y = 174

y = 58°

Step 5: Find x by plugging y back into an original equation

x + 58 = 180

x = 122°

Step 6: Rewrite

x = m∠6

y = m∠7

m∠6 = 122°

m∠7 = 58°
