Step 1: Turn the mixed numbers into improper fractions.

2 4/5 = 14/5

2 1/5 = 11/5

Step 2: Turn the improper fractions into decimals.

14/5 = 2.8

11/5 = 2.2

Step 3: Divide the fractions.

2.8 ÷ 2.2 = 1.27 when rounded to the nearest hundred.

A large bakery produces cakes in an assembly line. Sergio noticed a potential defect that seems to be showing in
every other cake. He decides that in the next production run, he'll take a random sample of cakes to get a better
idea of how many cakes might have this defect.
Why might Sergio choose a simple random sample instead of a systematic random sample?

Answers

The system random sampling involves the introduction of a sampling interval during the sampling process. Hence, the use of a fixed interval is more likely to miss the potential defect noticed based on the sampling interval selected.

The systematic random sampling simply involves choosing a fixed sampling interval during the sampling process.

A simple random sampling however selects a truly random sample from a population and this techniques provides the best sample which is representative of the population.

Since a sampling interval is required for a systematic random sample, the sample obtained for different values of k, which is the sampling interval will differ leading to a potential risk of missing the target .

Therefore, with simple random sampling, Sergio stands a better chance of capturing the defect better than using systematic random sampling

Answer:

If the defect is in every other cake, a systematic random sample could miss it completely depending on what Sergio chooses for kkk.

(a - b)² = a² + b² - 2ab , thus

a² + b² - 2ab = (a - b)² ( add 2ab to both sides )

a² + b² = (a - b)² + 2ab = 4² + 2(2) = 16 + 4 = 20

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?

Answers

Answer:

We get value of the value of b = 5

Step-by-step explanation:

We have slope m: [tex]m=-\frac{1}{6}[/tex]

We need to find value of b (y-intercept)

Using the point A(-6,6) and slope [tex]m=-\frac{1}{6}[/tex] we can find b.

Using slope-intercept form, putting values of m and x and y we get the value of b:

[tex]y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5[/tex]

So, we get value of the value of b = 5

Jane is thirteen years younger than twice Ruby’s age. Nora is 5 years older than Ruby. If their ages sum to 52, find each girl’s age.

Answers

Answer:

J=17 N=20 R=15

Step-by-step explanation:

J=Jane

R=Ruby

N=Nora

J=2R-13

N=5+R

J+N+R=52

(2R-13)+(5+R)+R=52

Slove for R and plug into each equation

Answer:

Ruby is 15, Jane is 17 and Nora is 20.

Step-by-step explanation:

Let x represent the age of Ruby.

Jane: 2x - 13

Ruby: x

Nora: x + 5

52 = (x) + (2x - 13) + (x + 5)

52 = x + 2x - 13 + x + 5

52 + 13 - 5 = x + 2x + x

60 = 4x

x = 15

Jane:

2(15) -13

= 17

Nora:

(15) + 5

= 20
