Jet001 [13]

To determine the ratio of the lengths of the red and blue ribbon, we just have to divide the lengths of the corresponding colored ribbon.
red / blue = 3/4 / 2/3 = 9/8
(2) The ratio of the lengths expressed as a unit rate is 9/8:1
(3) The ratio of the lengths of the blue to red ribbon is the reciprocal of the calculated value above giving us the answer of 8/9.

17.5% of 120 can be worked out using the following method find 10% of 120=12 then 5% of 120=6 then 2.5% of 120=3. Adding 17.5% o

Answer:

17.5% of 360 = 63

Step-by-step explanation:

We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find 10% of 360 , we get,

$\frac{10}{100} \times 360=36$

STEP 2 : find 5% of 360, we get,

$\frac{5}{100} \times 360=18$

STEP 3: find 2.5% of 360 , we get,

$\frac{2.5}{100} \times 360=9$

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360

⇒ 17.5% of 360 = 36 + 18 + 9

⇒ 17.5% of 360 = 63

Answer:

.13%

68.26%

2.28%

47.72%

49.87%

34.13%

Step-by-step explanation:

1.) standardize by subtracting the mean and dividng by the standard deviation

(625-1000)/125= -3

go to a ztable to get .0013 or (1-.9987)

this is equal to .13%

2.)

875<x<1125

standardize both seperately and subtract them

(875-1000)/125= -1 whose probability is .1587 (or 1-.8413)

(1125-1000)/125= 1 whose probability is .8413

.8413-.1587= 68.26%

3.)

Find the probability that someone paid less than 1250 and take its compliment

(1250-1000)/125= 2 which has a probability of .9772

take its compliment (1-.9772)= .0228= 2.28%

4.)

Same process as question 2

(750-1000)/125= -2 which has a probability of (1-.9772) = .0228

(1000-1000)/125= 0 which has a probability of .5

.5-.0228= .4772= 47.72%

5.) same deal as the previous question

(625-1000)/125= -3 which has a probability of (1-.9987)= .0013

(1000-1000)/125= 0 which has a probability of .5

.5-.0013= .4987= 49.87%

6.)same deal the previous question

(875-1000)/125= -1 which has a probability of (1-.8413)=.1587

(1000-1000)/125= 0 which has a probability of .5

.5-.1587= .3413= 34.13%

How do I do this im having trouble and its my exam day?

Gnom [1K]

Answer:

Step-by-step explanation:

So basically set (10x-13) equal to (3x+22) and then solve for x

x=5

Plug 5 into the equations

(10(5)-13)=37

(3(5)+22)=37

These two angles are congruent due to the triangle being isosceles

37+37=74

All angles in a triangle are equal to 180 degrees

Therefore 180-74=106

Angle JKL= 106 degrees

Hope this helps :)

C because K is 1,-8 so if you go up 1, -7, and right 4,5. So you get k(5,-7)
