Yes, the point near 10 is an outlier because it is a variable far away from the others, it may effect your answer (if needed).

Emily needs enough Fabric for 3 1/2 hats. Since she has half a hat done. If each bag requires 1 2/7 ft of Fabric, how much fabri

kow [346]

first off let's convert the mixed fractions to improper fractions.

$\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1\frac{2}{7}}\implies \cfrac{1\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{9}{7}}$

she already did half a hat, so we can say $\cfrac{7}{2}-\cfrac{1}{2}\implies \cfrac{7-1}{2}\implies 3$

so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so

$3\cdot \cfrac{9}{7}\implies \cfrac{27}{7}\implies 3\frac{6}{7}$

As your costumer increases, your list goes as follows, 12, 14, 16, 18,....

aleksandr82 [10.1K]

Answer:

1. 24

2. $10+2n$ where n denotes number of days.

3. 70

Step-by-step explanation:

1.

Consider the sequence: $12,14,16,18,...$

Here,

$14-12=2\\16-14=2\\18-16=2$

Take the common difference as d = 2 and the first term as a = 12

Use the formula: $a_n=a+(n-1)d$

To find expected gain at the end of the week, find $a_7$

$a_7=12+(7-1)2\\=12+6(2)\\=12+12\\=24$

2.

Yes, the gain shows the pattern.

Put $a=12,d=2$ in $a_n=a+(n-1)d$

$a_n=12+(n-1)2\\=12+2n-2\\=10+2n$

Here, n denotes number of days.

3.

To find expected gain at the end of 30 days, put $n=30$ in $a_n=10+2n$

$a_{30}=10+2(30)\\ =10+60\\=70$
