Bianca is making scarves to sell. She has 33 peices of blue fabric, 37 peices of green fabric, and 41 peices of red fabric. Supp
Masja [62]

Answer:

I did my work, and I got 37 scarves. I feel really bad bc I am not 100% sure, and I hate when I am not 100% sure.

Step-by-step explanation:

For if you need to show your work:

33 pieces of blue fabric --> it can make 11 scarves exactly

37 pieces of green fabric --> it can make 12 scarves, with 1 piece of fabric left over

41 pieces of red fabric --> it can make 13 scarves, with 2 pieces of fabric left over

Left over fabric --> there are 3 pieces of fabric left over; 1 green and 2 red. This results in 1 more scarf

So lets add up our scarves: 11 scarves + 12 scarves + 13 scarves + 1 more scarf

That equals 37 scarves!

I hope this helps. Please <em><u>mark brainliest</u></em><em>, </em>I would really appreciate it if you did

Alex is a member of the school track and field team. His times for running various distances are shown. Create a scatter plot fo
frozen [14]

Answer:

(1) Please find attached the graph of the data

(2) 160.396 m

(3) The correlation that exist is a straight line correlation

Step-by-step explanation:

The given data are;

Distance,         Time

(m),                    (s)  

50,                    6.1

100,                   12

150,                   18.3

200,                  25.2

250,                   31.7

(2)

Based on the linear regression formula, we have;

b = \dfrac{N\sum XY - \left (\sum X  \right )\left (\sum Y  \right )}{N\sum X^{2} - \left (\sum X  \right )^{2}}

b = \dfrac{5 \times 17215 - 93.3 \times 750}{5 \times 2156.03 -8704.89} = 7.758

a = \dfrac{\sum Y - b\sum X}{N}

a = \dfrac{750 - 7.7581 \times 93.3}{5}= 5.234

The line is

y = 7.7581×x+5.234

When t = 20 s, we have

y = 7.7581*20+5.234 = 160.396 m

(3) The correlation that exist is a straight line correlation
