Solve: 4|x-1|+2=0:{{{{{{{{{

Answers

Answer 1
Answer: no solution
Explanation: 4|x-1| = -2 (subtract 2 from both sides)
|x-1| =-2/4 (divide by 4 on both sides)
|x-1| =-1/2 (simplify)
|x-1| =-1/2
Anything that comes out of an absolute value sign must be positive. But because this is not, this is no solution.

Given that k-5, k+7, k+55 are three consecutive terms in a geometric sequence, solve for k​

Answers

Answer:

[tex]k = 9[/tex]

Step-by-step explanation:

Given:

Consecutive Terms:  k-5, k+7, k+55

Required:

Determine the value of k

To do this, we make use of the concept of common ratio.

The common ratio (r) of a geometric sequence is:

[tex]r = \frac{T_{n}}{T_{n-1}}[/tex]

In other words:

[tex]r = \frac{T_3}{T_2} = \frac{T_2}{T_1}[/tex]

Where 1, 2 and 3 represents the terms of the progression/sequence

So:

[tex]r = \frac{T_3}{T_2} = \frac{T_2}{T_1}[/tex] becomes

[tex]\frac{k+55}{k+7} = \frac{k+7}{k-5}[/tex]

Cross Multiply:

[tex](k+55)(k-5) = (k+7)(k+7)[/tex]

Open Brackets

[tex]k^2 + 55k - 5k - 275 = k^2 + 7k + 7k + 49[/tex]

[tex]k^2 + 50k- 275 = k^2 + 14k + 49[/tex]

Collect Like Terms

[tex]k^2 - k^2 + 50k-14k = 275 + 49[/tex]

[tex]36k = 324[/tex]

Solve for k

[tex]k = 324/36[/tex]

[tex]k = 9[/tex]

Complete the blank with either ∈ or ∉ so that the resulting statement is true. −2​__{−6,−3,−5,−1}

Answers

Answer:

−2​ ∉ {−6,−3,−5,−1}

Step-by-step explanation:

Given

Set = {−6,−3,−5,−1}

Element = -2

Required

The interpretation of the question is to state if -2 is an element of the given set or not

The first thing to do is to check through the set to count the number of occurrence of -2

Looking through Set = {−6,−3,−5,−1}, we have that the occurrence of -2 is 0

This implies that -2 is not an element of the given set and this is represented by the symbol ∉

Hence:

−2​ ∉ {−6,−3,−5,−1}

Question 2 options: A consumer advocate group selects a random sample of 205 snack foods and finds that 174 of them contain more fat grams than what is indicated in the snack's nutritional information. Create a 90% confidence interval for the population proportion for snack foods that contain more fat grams that what is indicated in the snack's nutritional information.

Answers

Answer:

156 snack foods.

Step-by-step explanation:

205 - 174 = 31

To find 90% of 174, multiply 174 by 0.90.

174 x 0.90 = 156

The answer is 156 snack foods.

Seats in commercial airplanes are designed so most passengers are comfortably seated. To design an airplane, an engineer at Bombardier Aerospace uses the normally distributed height of Québec adults, which has a mean of 170 cm and a standard deviation of 12 cm
a. The designer will design the seating so 98% of passengers are comfortable. What is the height of someone who is taller than 98% of all other Québec adults?
b. The airplane can hold up to 110 passengers. What is the probability that the average height of passengers is smaller than 100 or larger than 190 cm?
c. If we market this airplane to the American market for which the mean height of adult Americans is 185 cm with a standard deviations of 16 cm, what proportion of American adults would be taller than the height found in (a)? Would this be a problem for Bombardier when it tries to sell the plane to American airline companies?

What fraction is equal to 75% of 1/2?​

Answers

Answer:

4/8

Step-by-step explanation:

To do this, multiply the whole fraction by 4/4 (which is like multiplying by 1/1). So 1/2 x 4/4 becomes 4/8 :)

Answer:

3/8 i think

Step-by-step explanation:

 Try changing the top of the fraction to something divisible by 4, like 4 for example.

To do this, multiply the whole fraction by 4/4 (which is like multiplying by 1/1).

So 1/2 x 4/4 becomes 4/8.

if you consider each 1/8 to be 25% and 75÷3 equals 25+25+25:

So, 75% of 4/8 is 3/8.

Another quick way is to just multiply 1/2 by 3/4 (since you know 3/4 equals 75% {think 75/100 reduced is 3/4}) and you get 3/8 as well

Answer:

I don't know the answer but I know it is not AB II DC because I did this assignment and got this wrong. This is just to narrow your answer choices down, sorry if this isn't helpful.

Step-by-step explanation:

The line AD is parallel to the line BC. Therefore, option B is the correct answer.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

Given that,  m∠3 = m∠B

The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Here, m∠3 and m∠B are corresponding angles and they are equal in measure.

So, AD || BC

Therefore, option B is the correct answer.
