Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to t

Harman [31]

Answer:

The ratio of the number of Lisa’s stickers to the number of John’s stickers is 3/2

Step-by-step explanation:

Step 1

Let

x ----> the number of stickers that Lisa has

y ----> the number of stickers that John has

we know that

$x+y=60$ ------> equation A

$x=y+12$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$(y+12)+y=60\\ 2y=60-12\\ 2y=48\\ y=24$

Find the value of x

$x=y+12$ -----> $x=24+12=36$

therefore

Lisa has 36 stickers and John has 24 stickers

Step 2

Find the ratio of the number of Lisa’s stickers to the number of John’s stickers

x/y

substitute

$\frac{36}{24}=\frac{3}{2}$

8. You recorded the time in seconds it took for 8 participants to solve a puzzle. The times were: 15.2, 18.8, 19.3, 19.7, 20.2,

Ivanshal [37]

Answer:

Xbar = 20.813

Median = 19.95

5 - number summary :

Minimum = 15.2

Q1 = 19.05; Q2 = 19.95 ; Q3 = 21.95 ; maximum = 29.4

Standard deviation, s = 4.068

Step-by-step explanation:

Given the data:

X : 15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4

Ordered data:

15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4

The mean (xbar) :

Xbar = Σx / n ; n = sample size = 8

Xbar = 166.8 / 8 = 20.8125

Xbar = 20.813

The median :

1/2 *(n+1)th term

1/2(9) = 4.5

(4 + 5)th term / 2

(19.7 + 20.2) / 2 = 19.95

The five number summary :

Minimum = 15.2

Lower quartile (Q1) = 1/4(9) = 2.25 ; (2nd + 3rd) term / 2

(18.8 + 19.3) / 2 = 19.05

Median (Q2) = 19.95

Upper quartile (Q3) :

3/4(9) = 6.75 = (6th + 7th) / 2

(21.8 + 22.1) / 2 = 21.95

Maximum = 29.4

The standard deviation, s = sqrt[(x - xbar)²/ (n-1)]

Using calculator ;

s = 4.068

5/2 (7x-15)+x>13/2-3/2

Evgen [1.6K]

5(7x - 15) + 2x ≥ 13x - 3 multiplied both sides by 2 to clear the denominator

35x - 75 + 2x ≥ 13 x - 3 distributed 5 into 7x-15

37x - 75 ≥ 13x - 3 added like terms (35x and 2x)

24x - 75 ≥ -3 subtracted 13x from both sides

24x ≥ 72 added 75 to both sides

x ≥ 3 divided both sides by 24

Answer: x ≥ 3 Notation: [3, ∞)
