what is the answer for
3x÷2=6​

Answer:

Step-by-step explanation:

it would be "c" because the question asks for the number that makes the inequality true

4x≤ x+3

the graph in c is saying that every number that is 1 or less than 1 makes the inequality true. so lets take -7 as an example

4 x -7=-28

-28+3=-25

-25 is greater than -28 so the inequality is true. the reason why graph d doesnt work is because if we plug in 2 into the equation, then 4x =8 and x+3=5

5 is not greater than 8 so it doesnt work

Given:

The highest age of the lottery winner is 83 years.

The smallest age of the lottery winner is 23 years.

Required:

We need to find the range of the data.

Explanation:

Consider the formula to find the rage of the data.

Substitute maximum value = 83 and minimum value = 23 in the equation.

Final answer:

The answer is D: conjecture

The key words in the description are "look for a pattern and then form an educated guess." This suggests making a hypothesis or assumption based on the observed pattern, which is the definition of a conjecture.

The other answer choices are defined as follows:

A. conjugation - the act of changing a verb to agree with its subject

B. conjunction - a connecting word

C. congruence - the state of agreeing, matching, or coinciding

D. conjecture - an opinion or conclusion formed on the basis of incomplete information

So option D, conjecture, is the best match for forming an educated guess based on an observed pattern in induction.

Answer: 192.. just took the test :)

Step-by-step explanation:

The number of  boxes contains more than 340 nails will be 190. Option B is correct.

The number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured is known as the Z score.

Z score for the 340 nails is found as;

\(\rm Z-score= \frac{340-325}{15} \\\\ Z-score=1\)

If the probability of the z score is grater than 1 is;

P(Z≥1)=1-P(Z≤1)

P(Z≥1)=1-0.8413

P(Z≥1)=0.1587

For the 1200 boxes with more than the 340 nails is 192.

Hence,option B is correct.

The maximum value of the function f (x) = -1.8x² + 7x - 11 to the nearest hundredth is,  - 4.19.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

The function is,

⇒ f (x) = -1.8x² + 7x - 11

Now, We can differentiate with respect to x as;

⇒ f ' (x) = - 1.8 × 2x + 7 × 1 - 0

⇒ f ' (x) = - 3.6x + 7

Put f ' (x) = 0

⇒ - 3.6x + 7 = 0

⇒ 3.6x = 7

⇒ x = 1.94

Now, Again differentiate with respect to x as;

⇒ f ' (x) = - 3.6x + 7

⇒ f '' (x) = - 3.6 × 1 + 0

⇒ f '' (x) = - 3.6 < 0

Hence, Substitute x = 1.94 in function to get maximum value,

⇒ f (x) = -1.8x² + 7x - 11

⇒ f (x) = -1.8 (1.94)² + 7 × 1.94 - 11

⇒f (x) = - 6.77 + 13.58 - 11

⇒ f (x) = - 4.19

Thus, The maximum value = - 4.19

The addition of the given fraction expression is 7/8.

In mathematics, an expression is a combination of numbers, symbols, and/or operators that represents a mathematical quantity or relationship. It can be a simple combination of numbers or a more complex combination involving variables, functions, or other mathematical constructs.

When adding fractions with the same denominator, you simply add the numerators and keep the denominator the same.

In this case, both fractions have a denominator of 8, so we can add their numerators:

5/8 + 2/8 = (5 + 2)/8 = 7/8

Thus, the sum of 5/8 and 2/8 is 7/8.

Answer:

x+100

Step-by-step explanation:

x^2-10,000/x-100

x^2-10000 is a difference in squares and can be factored.

x^2-10000 = (x+100)(×-100).

(x+100)(x-100)/(x-100)

(x-100) cancel each other.

x+100 remains.

The value of the angle U from the calculation is 88 degrees.

The sine rule can be applied in a variety of situations, such as determining a triangle's unknown side lengths or angles. The sine rule can be used to locate the missing side or angle if you know the lengths of two sides and the measure of an angle (not necessarily the included angle).

By the use of the sine rule;

u/Sin U = w/Sin W

Thus;

76/Sin U = 71/Sin 69

Sin U = 76Sin 69/71

U = Sin-1 (76Sin 69/71)

Answer:

a) 10

b) 10000

c) 100

d) 1000

Step-by-step explanation:

With 0.80 × 10, we move the decimal up one place, so it equals 8.0 or 8

10000 × 0.002, we move the decimal up four places, so it equals 0020.0 or 20

0.04 × 100, we move the decimal up two places, so it equals 04.0 or 4

Lastly, 1000 × 0.5, we move the decimal up three places, so it equals 500.0 or 500

Using the powers of ten, we either move the decimal up or down according to the number of zeros.

Hello your question is incomplete below is the missing part of the  question

Metropolitan Research, Inc., a consumer research organization, conducts surveys designed to evaluate a wide variety of products and services available to consumers. In one particular study, Metropolitan looked at consumer satisfaction with the performance of automobiles produced by a major Detroit manufacturer. A questionnaire sent to owners of one of the manufacturer's full-sized cars reviewed several complaints about early transmission problems. To learn more about the transmission failures, Metropolitan used a sample of actual transmission repairs provided by a transmission repair firm in the Detroit area. The following data show the actual number of miles driven for 50 vehicles at the time of transmission failure:

 4.) How many repair records should be sampled if the research firm wants the population mean number of miles driven until transmission failure to be estimated with a margin of error of 5000 miles? Use 95% confidence.

answer : 1) Min value = 25070  1st quarter = 60420,Median = 72700,Mean = 73340,3rd quarter = 86580,Max value = 138100

2)  ( 66438.73, 80241.87 )

3) The statistical results shows that some owners of the automobiles experienced early transmission failures

4) 95

Step-by-step explanation:

1) The transmission failure ( using descriptive statistics )

Min = 25070

1st quarter = 60420

Median = 72700

Mean = 73340

3rd quarter = 86580

Max = 138100

2) managerial interpretation of interval estimate

given 95% confidence interval

a = 0.05

z(0.025) = 1.96

Hence the 95% confidence interval for the mean number of miles driven until transmission failure

= xbar +/- Z*s/vn

⇒ 73340.3 +/- 1.96*24898.72 * \(\sqrt{50}\)

= ( 66438.73, 80241.87 )

3) The findings shows that some owners of the automobiles experienced early transmission failures

4 ) number of repair records

n = ( Z * S/E) ^2   ------- 1

Where : Z = 1.96, S = 24898.72, E = 5000

 = 1.96 * 24898.72 / 5000 ) ^2

 = 95

Answer:

116°

Step-by-step explanation:

(Angle sum property of a triangle = 180°)

angle A + angle C + angle ABC = 180°

66° + 50° + angle BAC = 180°

116° + angle ABC = 180°

angle ABC = 180° - 116°

angle ABC = 64°

angle ABD + angle ABC = 180°

angle ABD + 64° = 180°

angle ABD = 180° - 64°

angle ABD = 116°

So, the measure of the unknown angle is 116°

The mean score to the nearest whole number is equal to 5.0

In Mathematics and Geometry, the mean for this set of data can be calculated by using the following formula:

Mean = [F(x)]/n

For the total number of data based on the frequency, we have;

Total score, F(x) = 1(3) + 2(1) + 3(4) + 4(10) + 5(15) + 6(9) + 7(3) + 8(5)

Total score, F(x) = 3 + 2 + 12 + 40 + 75 + 54 + 21 + 40

Total score, F(x) = 247

we can make this into an  equation

-155+117=-38!

the location of the sub is 38 meters below sea level.

if it only has one root and is a 2nd degree polynomial, that means that the only one root has multiplicity of 2, or namely is repeated twice.

The median would be 22:

Step-by-step explanation: The median is the number that is in the middle

Simply defined, the median is the number right in the middle of a set.

But before I get down to finding the median, I will order the numbers from least to greatest:

15, 17, 19, 20, 21, 22, 23

Now, the middle number is 20. So that's the median.

As for the range, it's the difference between the largest number and the smallest one:

Range = Greatest number - Smallest number

           = 23 - 15

           = 6

In summary, the median, the number in the middle, is 20, and the range, the difference between the largest number and the smallest one, is 6.
