Answer:

The two fractions are equivalent; another equivalent fraction is 3/6

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] x 4 = 4/8, therefore the fractions are equivalent.

1/2 x 3 = 3/6 which is equivalent to 1/2.

Bruh just open a calculator app lol

Answer:

(a) 0.90

(b) 0.9001

Step-by-step explanation:

[tex]X_{i}\sim N(50, 100);\ i=1,2,3...16[/tex]

(a)

[tex]P ( 796.2 < \sum\limits^{16}_{i=1}{(X_{i} - 50)^{2} < 2630)=P ( \frac{796.2}{100} < \sum\limits^{16}_{i=1}{(\frac{X_{i} - 50}{10})^{2} < \frac{2630}{100})[/tex]

                                                    [tex]=P ( 7.962 < \sum\limits^{16}_{i=1}{Z_{i}^{2} < 26.3)\\=P ( 7.962\leq \chichi^{2}_{16} \leq 26.3)\\\\=P(\chi^{2}_{16}\leq 26.3)-P(\chi^{2}_{16}\leq 7.962)\\\\=0.90[/tex]

*Use the chi-square table.

(b)

[tex]P ( 726.1< \sum\limits^{16}_{i=1}{E(X_{i}-\bar X)^{2} < 2500)=P ( \frac{726.1}{100} < \frac{(n-1)S^{2}}{\SIGMA^{2}}< \frac{2500}{100})[/tex]

                                                    [tex]=P ( 7.261\leq \chi^{2}_{16-1} \leq 25.0)\\\\=P(\chi^{2}_{15}\leq 25.0)-P(\chi^{2}_{15}\leq 7.261)\\\\=0.9001[/tex]

*Use the chi-square table.

Answer: B. Angle ABC is an obtuse angle

Step-by-step explanation:

ANSWER:

f(x) = x²-1

g(x) = x-1

f/g (x)=

x²-1÷x-1 = x-1

Answer:

First break up 72 into

36 x 2 x -1

Then take the square root of 36

6 square root 2 x -1

Finally make square root -1 = i

6i square root 2 is your answer

Step-by-step explanation:

Answer:

5.  -(6/5)

6. 1/5

7. I think 4/25 but i am not full sure

8. 2

9. -(5/8)

Step-by-step explanation:

Answer:

-324

Step-by-step explanation:

First, you need to just multiply the two numbers together.

36 * 9

This would give you the overall answer. Then you determine if when you multiply the numbers, if you'd need to add the integer, a.k.a, the negative sign.

Since when you multiply a negative and a positive, the answer will be negative.

So, 36 * (-9) = -324

Answer:

A) 72

Step-by-step explanation:

Okay well sice the lines AC and BD are parrallel that tells you that angles 4 is equal to 7 and angle 3 is equal to 8. Knowing this helps, now angle 3 and 4 have to equal 180 degrees cause it a strioght line. so do 180 - 108 (angle 3) equals angle 4. Once you find angle 4 degrees its the same as angle 7.

Answer:

89

Step-by-step explanation:

80+82+83+91+89 = 425

425/5 = 85

Answer:

2.42

Step-by-step explanation:

First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.

Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.

Y1-15.54=10.36x -15.54 get y1 by itself

Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42

Answer/Step-by-step explanation:

According to the centroid theorem, the X is ⅔ of the distance from each vertex to the midpoint of the opposite side.

Thus:

1. If CW = 15,

CX = ⅔*(15)

CX = 10

XW = ⅓*(15)

XW = 5

2. If BX = 8,

BX = ⅔*BY

3*BX = 2*BY

(3*BX)/2 = BY

(3*8)/2 = BY

24/2 = BY

12 = BY

BY = 12

XY = ⅓*BY

XY = ⅓*12

XY = 4

3. If XZ = 3, find AX and AZ.

XZ = ⅓*AZ

XZ*3 = AZ

3*3 = AZ

9 = AZ

AZ = 9

AX = ⅔*AZ

AX = ⅔*9

AX = 6

Answer:

Monica paid $171 while Rachel paid $207

Step-by-step explanation:

We are told that Monic and Rachel purchased a tv for $378.

Let the amount spent by Monica be X and the amount spent by Rachel be Y.

Thus;

x + y = 378 - - - - (eq 1)

We are told that Monica paid $36 less then Rachel. Thus;

y = x + 36

Or y - x = 36 - - - (eq 2)

Add eq 1 & eq 2 together to give;

2y = 378 + 36

2y = 414

y = 414/2

y = $207

Put 207 for x in eq 1 to get;

x + 207 = 378

x = 378 - 207

x = $171

Thus;

Monica paid $171 while Rachel paid $207
