what is the answer to this problem?

In linear equations, 64% of samples have nitrogen levels and phosphorus levels that are low.

What is linear equations?

P(low nitrogen) = 46% = 0.46

P(low phosphorus) = 28% = 0.28

P(low nitrogen and low phosphorus) = 10% = 0.10

P(low nitrogen or low phosphorus) = P(low nitrogen) + P(low phosphorus) - P(low nitrogen and low phosphorus)

= 0.46 + 0.28 - 0.10

= 0.64 = 64%

Hence , 64% of samples have nitrogen levels and phosphorus levels that are low.

Answer:

∠ TVW = 65°

Step-by-step explanation:

∠ UVW = ∠ TVW + ∠ UVT ( substitute values )

21x + 6 = 8x + 9 + 88

21x + 6 = 8x + 97 ( subtract 8x from both sides )

13x + 6 = 97 ( subtract 6 from both sides )

13x = 91 ( divide both sides by 13 )

x = 7

Then

∠ TVW = 8x + 9 = 8(7) + 9 = 56 + 9 = 65°

Step-by-step explanation:

Daniela : nice definition

Ori : part is right, but part is not

Kaori : incorrect

Daniela would not even have to say, that the lines are distinct. in any case, yes if you don't change anything about the appearance of the lines, but can move them on top of each other. and they completely blend in with each other, then yes they are parallel.

Ori is wrong about the part that they have to be close together. the second line could be in another galaxy, but if they are in the same plane and never intersect each other, then they are parallel.

Kaori is wrong by understanding that parallel means to opposite of perpendicular. perpendicular just means that the 2 lines are intersecting each other at a right angle (90°). but they can intersect at any other angle. that makes them not perpendicular, but they still intersect each other. so, they are not parallel.

Considering the definition of an inequality, the number of minutes she will run today will be more than 72 minutes.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being "t" the number of minutes Raina will run today, the inequality is

t÷ 8> 9

Solving:

t > 9×8

t > 72 minutes

Finally, the number of minutes she will run today will be more than 72 minutes.

Given in the picture that [tex]D=b^{2} -4ac[/tex]. and the value of Quadratic equation is  [tex]b=\sqrt{65}[/tex].

(a) Express b in terms of a, c and D.

[tex]b=\sqrt{D-4ac}[/tex]

(b) Find the values of b when a=2, c=-2 and D=81.

[tex]b=\sqrt{65}[/tex]

By seeing the question we can say that the [tex]b^{2} -4ac[/tex] is in the quadratic formula.

We know the general Quadratic Equation is [tex]ax^{2}+bx+c=0[/tex].

The solution to find the root of the Quadratic Equation is Quadratic Formula: [tex]\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}[/tex].

The whole solution is depend on [tex]b^{2} -4ac[/tex]. The team is called discriminant.

(a) Given that,

[tex]D=b^{2} -4ac[/tex]

[tex]b^{2}=D +4ac\\[/tex]

Taking square root on both sides.

[tex]\sqrt{b^{2} } =\sqrt{D+4ac}\\ b=\sqrt{D+4ac}\\[/tex]

Therefore, [tex]b=\sqrt{D-4ac}[/tex]

(b) Given that,

a=2,c=-2 and D=81

[tex]b=\sqrt{D+4ac}\\[/tex]

[tex]b=\sqrt{81+4(2)(-2)}\\[/tex]

[tex]b=\sqrt{81-16}[/tex]

[tex]b=\sqrt{65}[/tex]

Therefore, [tex]b=\sqrt{65}[/tex]

A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is a[tex]x^2[/tex] + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant factor. The first requirement for an equation to be a quadratic equation is that the coefficient of [tex]x^2[/tex] is not zero (a 0). When expressing a quadratic equation in standard form, the [tex]x^2[/tex]term comes first, then the x term, and finally the constant term.

If the distance,d, traveled by a particle is directly proportional to the square of the time,t, taken, when t = 40, d = 30, then the formula for d in terms of t will be d = 0.01875(t²).

Proportionality can be described as the property of being in a proper correlation in terms of size or quantity. In this problem, the distance is directly proportional to the square of the time which means that the distance increases as the square of the time is increased and vice versa.

Therefore,

d ∝ t²

d = kt² ( when t = 40 and d = 30 )

Here k is the constant

The value of k can be found by rearranging the equation,

d = kt²

30 = k(40²)

30 = k(1600)

k = 30 / 1600

k = 0.01875

As k = 0.01875, the formula for d in terms of t can be given as,

d = kt²

d = 0.01875(t²)

Answer:  a₁=6   a₉=-26

Step-by-step explanation:

a₂=2    a₆=-14    a₁=?     a₉=?

a₂=a₁+(2-1)d

a₆=a₁+(6-1)d

a₁+d=2    (1)

a₁+5d=-14  (2)

Subtract equation (1) from equation (2):

4d=-16

Divide both parts of the equation by 4:

d=-4

Hence,

a₁+(-4)=2

a₁-4+4=2+4

a₁=6

a₉=a₁+(9-1)d

a₉=6+8(-4)

a₉=6+(-32)

a₉=6-32

a₉=-26

The unknown angles on the straight line are as follows:

∠RQT is a straight angle.

Therefore,

∠RQT = 180 degrees(angle on a straight line)

Therefore, let's find m∠RQS and m∠TQS

∠RQT = m∠RQS + m∠TQS

where,

m∠RQS = 10x + 9

m∠TQS = 7x + 1

Therefore,

∠RQT = 10x + 9 + 7x + 1

∠RQT = 17x + 10

180 - 10 = 17x

170 = 17x

divide both sides by 17

x = 170 / 17

x = 10

Therefore,

m∠RQS = 10(10) + 9 = 109°

m∠TQS = 7(10) + 1 = 71°

Response bias results from the possibility that not all sophomore students provided accurate information about their drug use, which will immediately result in the response bias because of false data.

Response bias is a catch-all phrase for a variety of inclinations for participants to give misleading or inaccurate answers to queries. These biases are common in studies involving participant self-report, such as structured interviews or surveys. The validity of questionnaires or surveys can be significantly impacted by response biases.

The idea that human subjects do not passively respond to stimuli but rather actively integrate several sources of information to develop a response in a specific scenario is central to the concept that response bias can be induced or caused by a variety of causes. As a result, practically every element of an experimental condition has the ability to sway a respondent.

Explanation:

The remedy is to conduct a survey by licensed social workers since licensed social workers didn't explicitly ask sophomore students about drug use; instead, they interacted with the students as their friends before gathering the data.

2. To get the ratio for the mixtures, order the pairs (e.g. (6, 4), (15, 10), and check the proportion of each variable in the other variable, using the least common divisor.

A ratio is the proportion of each variable in the other.

Ratios are expressed using the ratio sign (:) or in fractions, decimals, or percentages.
