All checked baggage on a particular airline company must not exceed 64 inches or an additional fee is charged.

The size of the baggage is determined by adding length + width + height.

If a bag has a height of 22 inches and a width
that is 16 inches less than the length, what lengths are acceptable for the bag to be checked free of charge?

If the bag is to be checked free of charge. its length must be __ inches or less.

Answers

With the equation 22+x-16+x=64 you get x=29, therefor the length must be 29 inches or less.

officials begin to release water from a man made lake at a rate that would empty the lake in 16 weeks, but a river that can fill the lake in 30 weeks is replenishing the lake at the same time. how many weeks does it take to empty the lake? express you answer as a fraction reduced to the lowest terms, if needed.​

Answers

Answer:

34²/7

Step-by-step explanation:

Take the dam to be a take and the exit of the dam to be a tap at the bottom which is used to empty the tank and the river to be a pipe at the top of the tank that is used to fill the tank

The tap takes 16 week to empty the tank how much will it empty in 1 week =¹/16

The pipe takes 30 week to fill the tank how much will it fill in 1 week =¹/30

¹/16-¹/30= ?

Get the LCM of the denominator which is 240

The fractions are now

15/240-⁸/240=⁷/240

1week=⁷/240 empty

? = 240/240 empty

Cross multiple

240/240×1÷7/240

240/240×1÷240/7=240/7

7÷240=34²/7 weeks

-3x + 5y = 8
-2x + 7 y = -2​

Answers

Answer:

x = - 6

y = - 2

Step-by-step explanation:

-3x + 5y = 8  | ×(-2)

-2x + 7 y = -2​ | ×3

6x - 10y = - 16

- 6x + 21y = - 6

add

6x - 6x - 10y + 21y = - 16 - 6

11y = - 22

y = - 22 : 11

y = - 2

replace y

- 2x + 7(-2) = - 2

- 2x - 14 = - 2

- 14 + 2 = 2x

2x = - 12

x = - 12 : 2

x = - 6

What is the value of x? Enter your answer in the box. x = cm A bow tie shape polygon made of two bow ties that share a vertex. The shape is created by two segments intersecting forming two triangles with vertical angles. An alternate interior angle of the triangles are marked congruent to each other. The larger triangle is on the left and the smaller triangle is on the right. In the larger triangle, the left side of the triangle is 32 centimeters. The south side of the triangle is 40 centimeters. On the smaller triangle, the right side of the triangle is 4 centimeters. The north side of the triangle is labeled x.

Answers

Answer:

side x is 5 cm long

Step-by-step explanation:

Use proportions, given that the two triangles are similar because they contain three equal angles:

One angle due to connected by the vertex (oppose by the vertex), another angle as marked with the tick, and the third one has to be the same due to the fact that the addition of the three internal angles of a triangle must equal 180 degrees.

Then our proportion becomes:

[tex]\frac{4}{32} =\frac{x}{40}[/tex]

And then we solve for x by multiplying both sides by 40 (to eliminate the denominator on the right):

[tex]\frac{4}{32} =\frac{x}{40} \\\frac{4*40}{32} =x\\ x=5\,\,cm[/tex]

Which rule defines the function in the graph? Two line segments on a coordinate plane that do not meet.

The second segment begins at 2 comma 3, inclusive, and ends at 4 comma negative 3, inclusive. Group of answer choices f(x)={ x−1, if −3 ≤ x < 1 f(x)={ −3x+9, if 2 ≤ x ≤ 4 f(x)= { x−1 , if −3 < x ≤ 1 f(x)= {−3x+9 , if 2 < x < 4 f(x)={ x−1, if −3 ≤ x < 1 f(x)={ x−3, if 2 ≤ x≤ 4 f(x)={x−1, if −3 < x ≤ 1 f(x)={x−3, if 2 < x < 4

Answers

Answer:

The correct option is;

f(x) = {x - 1 if -3 ≤ x < 1 f(x) = {-3·x + 9, if 2 ≤ x ≤ 4

Step-by-step explanation:

The given coordinates of the points are;

For the first segment

Beginning point [-3, -4] (inclusive)

Endpoint (1, 0), (noninclusive)

For the second segment

Beginning point [2, 3] (inclusive)

Endpoint [4, -3] (inclusive)

The equation of the first segment is therefore;

y - 0 = (0 + 4)/(1 + 3)×(x - 1) = 1 × (x - 1)

y = x - 1

The equation of the second segment is found as follows;

y + 3 = (-3 - 3)/(4 - 2)×(x - 4) = -3 × (x - 4)

y + 3 = -3 × (x - 4) = -3·x + 12

y = -3·x + 12 - 3 = -3·x + 9

Therefore, we have;

f(x) = {x - 1 if -3 ≤ x < 1 and f(x) = {-3·x + 9, if 2 ≤ x ≤ 4

The American Auto Association reports that the mean price per gallon of regular gasoline is $3.10, with a population standard deviation of $0.20. Assume a random sample of 16 gasoline stations is selected and their mean cost for regular gasoline is computed. What is the likelihood the sample mean is greater than $3.08

Answers

Answer:

0.65542

Step-by-step explanation:

The formula for calculating a z-score when a random sample is selected is is z = (x-μ)/standard error

where

x is the raw score

μ is the population mean

Standard error = σ/√n

σ is the population standard deviation.

n = randomly selected sample

z = (x-μ)/standard error

z = (3.08 - 3.10) / 0.20/ √16

= -0.02/0.2/4

= -0.02/0.05

= - 0.4

Determining the Probability value from Z-Table:

P(x≤ 3.08) = P(<3.08)

P (z = -0.4)

= 0.34458

P(x>3.08) = 1 - P(x<3.08)

1 - 0.34458

= 0.65542

Therefore, the likelihood the sample mean is greater than $3.08 is 0.65542

Suppose a student just found out that she scored a 75 on her first statistics​ exam, with a​ z-score of 0.5. Her​ friend, who is in a different section with the same​ professor, also scored a 75 but had a​ z-score of −0.5. What can you conclude about the mean exam scores in the two​ classes?

Answers

Answer:

The mean exam scores in the second section is greater than the mean exam scores in the first section

Step-by-step explanation:

Here, we are interested in making a conclusion.

Mathematically;

z-score = (score - mean)/SD

so basically, what determines the sign of the z-score is dependent entirely on the mean.

If the mean is larger than the score, we will have a negative z-score. If the mean is smaller than the score, then will have a positive z-score

So basically what drives the sign is the mean value since the scores are the same for both students in this case, irrespective of the standard deviation in both classes.

So, for the first girl with a positive z-score, we can conclude that her score is larger than the mean; while for the second girl with a negative z-score, her score is smaller to the mean.

Thus, what we conclude here is that the mean score of the second section with the professor is greater than the mean score of the first section with the professor.

ANSWER = MY ETERNAL LOVE determine an equation of the line which is the perpendicular bisector of the segment whose endpoints are (-5,3) and (7,2). make sure to show all work.

Answers

Answer:

Perpendicular Bisector Equation: y = 12x - 9.500

Step-by-step explanation:

Let find out the midpoint for given coordinates as follows:

[(-5+7)/2, (3 +2)/2]

= (2/2, 5/2)

= (1,5/2)

The midpoint coordinates are (1,5/2) means (x1 , y2)

2. Find the slop of line for given coordinates as follows:

(2-3)/(7-(-5)

= -1/12

3. Find the negative reciprocal as follows

-1/12

= 12 (m)

4. Now find the perpendicular bisector equation as follows:

y – y1 = m ( x – x1)

y – 3 = 12 (x – (-5)

y = 12x - 9.5

The required equation of the line is x + 12y = 41 which is the perpendicular bisector of the segment whose endpoints are (-5,3) and (7,2).

What is a perpendicular bisector?

A perpendicular bisector is defined as a line that divides an angle into two equal angles.

The perpendicular bisector of the segment whose endpoints are (-5,3) and (7,2).

We have to determine the equation of the line

Let x₁ = -5, y₁ = 3 and x₂ = 7, y₂ = 2

The required of equation line is:

y - y₁ = (y₂ - y₁ )/( x₂ - x₁ )( x - x₁ )

Substitute the values in the formula to get the line,

y - 3 = (2 - 3)/(7 - (-5))(x - (-5))

y - 3 = (-1/12)(x+5)

12y - 36 = -x -5

x + 12y = 41

Thus, the required equation of the line is x + 12y = 41.

Write the expression as the sine cosine or tangent of an angle calculator.

Answers

Answer:

hello your question is incomplete here is the complete question

write the expression as the sine, cosine,  or tangent of an angle.

[tex]sin 60 cos 15 + cos 60 sin 15[/tex]

answer : [tex]sin 60 cos 15 + cos 60 sin 15 = sin 75[/tex]

Step-by-step explanation:

To write the expression as the sine,cosine or tangent of an angle we will employ the trigonometry identity

[tex]sin 60 cos 15 + cos 60 sin 15[/tex]  can be represented in the form of ;

sin( u + v ) = sin u cos v + cos u sin v --------- (1)

comparing equation 1 with the given expression

u = 60 and v = 15

therefore writing the expression in the form of the sine of an angle would be the answer

= sin( 60 + 15 )  = sin 60 cos 15 + cos 60 sin 15

hence sin ( 75 ) = sin 60 cos 15 + cos 60 sin 15

A random sample of 10 subjects have weights with a standard deviation of 9 8753 kg What is the variance of their weights? Be sure to include the appropriate units with the result.​

Answers

Answer: The variance of their weights = 9,752,155,009 kg.

Step-by-step explanation:

The variance is the square of the standard deviation . it measures the spread between data values in a data set.

So if standard deviation of 10 subjects = 98753 kg

Then, variance = [tex](9 8753 )^2\ kg=9,752,155,009\ kg[/tex]

Hence, the variance of their weights = 9,752,155,009 kg.

It was always cold in Mrs. Jaffreys class. It was always freezing in there. And every day I wore my coat to her class she told me not to. Why not? I asked her. Its cold in here. Im cold. Because youre not supposed to wear your coat to class, she kept saying. Seemed pretty stupid to me, so I kept wearing my coat to class, I was cold. After a few days, Mrs. Jaffrey told me to hang my coat in the principals office. Told me to stay there for the rest of the afternoon. Told me to write her a five hundred-word essay on why I shouldnt wear my coat to class. Why? I asked her. I cant do that. howm I supposed to do that? She looked at me over her horned-rims. Her lips were white. She had her arms folded. The north wind coming up off the practice fields outside glazed the windowpanes along the wall with ice. Be creative, she said. I sat in the principals warm office and wrote a hundred sentences, like the ones Id written on the detention hall chalkboard for Mrs. Jaffrey after school: I will not wear my coat to class because someone might mistake me for a bear and shoot me. I will not wear my coat to class because I might sweat so much the class will flood, and somebody might drown. I will not wear my coat to class because I might get so hot, Ill catch fire and burn the whole Junior High down. That kind of thing. It was more than five hundred words. I thought it was pretty creative. Mrs. Jaffrey didnt think so, though. Neither did my old man. Next day, he showed up outside Mrs. Jaffreys class with my essay in his hand. Checked me out of school. Told me to put on my coat. Its in the principals office, I told him Leave it then, he said. It was cold outside. Ice coated the trees, the rooftops of houses, the windshields of cars parked along the curbs, the sidewalks, the streets. The old man drove too fast, dodging fallen tree limbs in the road, his pickup truck sliding all over, down to Pecan Park. He told me to get out. Told me to open the tailgate. Told me to bend over and read each sentence, one at a time. There was a new two-by-four in the bed of the truck. The wood was white. He picked it up, stood behind me. I read a sentence, and then he hit me one. Then I read another sentence. He hit me again, there were a hundred sentences. He kept hitting me. The wind blew up hard and it started to sleet, and all around the park tree limbs groaned and cracked and snapped off. I didnt have my coat on. I was cold. Ice fell all around me.
