welll...you have there written just one relationship...it is berween 280 and 4 hours...you have to figure out speed:
it is speed per hour
then you just connect time and speed:
- 140 - 2
- 280 - 4
- 350 - 5
- 420 - 6
- 560 - 8
- 700 - 10
First, we establish
our hypothesis:
<span>Null hypothesis H0: μ = $1.00 </span>
Alternative hypothesis
Ha: μ ≠ $1.00
<span>Let’s say X = the sample average cost of a daily newspaper
= 0.96</span>
u = population mean
cost = 1.00
S = sample standard
deviation = 0.18
Calculating for z
value:
z = (X – u) / S
z = (0.96 – 1) / 0.18
z = – 0.222
From the standard
distribution table at this z value, p-value = 0.4129
Since alpha = 0.01,
the decision therefore is:
<span>Do not reject the null
hypothesis because the p-value is greater than 0.01. There is enough evidence
to support the claim that the mean cost of newspapers is $1. </span>
13 inches = 5 feet
----------------------------
Find 1 inch:
----------------------------
1 inch = 5/13 feet
----------------------------
Find 104 inches:
----------------------------
104 inches = 5/13 x 104 feet
104 inches = 40 feet
--------------------------------------------------------
Answer: 40 feet
--------------------------------------------------------
Answer: it's -1
Step-by-step explanation: Hope this helps

Shifting 4 units left (decreasing in x-axis by 4 units)
Shifting 5 units down (decreasing in y-axis by 5 units)
Apply to every vertices coordinates(x - 4, y - 5)
New coordinates
