Step-by-step explanation:

Answer:

the answer is c. constant interval

The graph for the first is line segment joining (x, y) = (−2,−4)and (2, 4), sans the end points. The second part is the line through (-2, -6) and (-3, -9), from (-2, -6), excepting (-2, -6). ..

Step-by-step explanation: you are using y for the piecewise function.

Answer:

so the question is going to be .B

Step-by-step explanation:

Answer: This is the graph for -x -2y=4

Answer:

$6.66 and $7.04

Step-by-step explanation:

I got it right

The $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]

σ is the standard deviation

xi is each value from the data set

X is the mean of the data set

n is the number of observations in the data set.

From the central limit theorem:

σ(x) = σ/√n

The standard deviation σ = $1.25

The sample n = 180

σ(x) = 1.25/√180

σ(x) = 1.25/√1801

σ(x) = 0.0931

The lower limit = 6.85 - 0.0931 = 6.756 = 6.76

The upper limit = 6.85 - 0.0931 = 6.943 = 6.94

Thus, the $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.

Answer:

option B is correct because

1 hectameter is equal to 10000cm

Answer:

1 7/8

Step-by-step explanation:

2 - 1/8 = 1 7 /8

1 7/8 + 1/8 = 2

Answer:

probably 145.15ft^2 but who really knows good luck

Step-by-step explanation:

we're gonna have to find the area of the square and circle and then subtract the square area to see the remaining shaded area's value. if the square has side of length 16 then we know it's area is 16ftx16ft=256ft^2. Now the area of the circle requires us to know its radius. we see the diagonal dashed line travels the diameter of the circle. you can use pythagoras theorem to find its length so sqrt(16^2+16^2)=22.63ft. but this is diameter and we want radius so 22.63/2=11.3ft. the formula for the area of a circle is pi*r^2 so pi*11.3^2=401.15ft^2. now we can say 401.15-256=145.15ft^2

Answer:

x=6.54

Step-by-step explanation:

Start off by cross multiplying what you are given ;)

6*109=654

Since you are solving for the missing variable x divide 654/100

The final answer will be 6.54

Hope this helps if not just reply so I can better explain

Answer:

99.75

Step-by-step explanation:

Answer:

10mins

Step-by-step explanation:

you can draw a rtd chart for this problem

             rate (m/min)|  time (mins)  | distance (m )

regular: (300/x)  | x  | 300m

fist 1/4 : (300/x) | 75: (300/x)  | 75m

last 3/4:  | (300/x)+15 | 225:(300/x + 15) | 225m

then, make an equation for the times:

x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x

// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop

solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer

Answer:

y = -2x + 28

Step-by-step explanation:

Slope intercept form is-

y = mx + b

y = y coordinate

m = slope, the rise/run

x = x coordinate

b = the y-intercept, the place the line crosses the y-axis.

Now, fill in the formula with the proper information.

y = -2x + b    You can use the point (10, 8) for the x and y coordinates to find b

  8 = -2(10) + b     Now solve for b

  8 = -20 + b

+20  +20

28 = b                    Now substitute 28 in for b

y = -2x + 28

Answer:

y-8=-2(x-10)

Step-by-step explanation:

y-y1=m(x-x1)

y-8=-2(x-10)

Answer:

4√13-6√13+10√13= 24

Step-by-step explanation:

Answer:

8√13

Step-by-step explanation:

Answer:

suppose: the age of the man now is x

the sum of the ages of his two sons now is y

(x, y > 0, x, y € N)

so the age of the man 10 years ago is x - 10

the sum of the ages of his 2 sons ten years ago is

y - 20

because now, The age of a man is twice the sum of the ages of his two sons => x = 2y

because Ten years ago, his age was five times

the sum of their ages

=> x - 10 = 5( y - 20)

<=> x - 10 = 5y - 100

<=> 2x - 20 = 10y - 200

<=> 2x = 2y.5 - 180

but x = 2y => 2x = 5x - 180

<=> 3x = 180

<=> x = 60

=> his present age is 60

Answer:

1.11g

Step-by-step explanation:

1 Table = 18.5 mg

60 Tablets = 60*18.5 = 1110 mg

1mg=0.001g

1110mg=1.11g

Step-by-step explanation:

Supplementary angles add up to 180 degrees

Complementary angles add up to 90 degrees

It is just a rule that is important to geometry

I hope that helps :)

Answer:

Add up to 180 degrees

Step-by-step explanation:

Supplementary angles can be two separate angles and the acute angles of a right triangle are complementary which make option 3 false. They are not always congruent and do not add up to 90 degree in total. Making option 1 and 4 false as well.

Answer:

I think the answer for the first one is 3 I am not sure about the second one

Answer:

1) are equal (congruent), are opposite from each other

2) (11y-36)= 63.

3) Add 36 to both sides.

11y = 99. Divide both sides by 11.

Y = 9

4) Next to each other, No numerical relationship
