Well you have to go by 24x3 and that equals 72 miles
Take 145-115 because for this your supposed to add all numbers inside to get exterior angle so you would do 145-115=30
R would be 30
R=30
Hope this helps
9-5=4. 4 is half the number so 4x2=8. Your number is 8.
Answer:
(a)23 (b)90 (c)3
Step-by-step explanation:
The equation for the line of best fit for this situation is given as
where x=average temperature in degrees
y=average number of hot dogs she sold,
(a) The expected number of hot dogs sold when the temperature is 50° would be___hot dogs.
When x=50°
When the temperature is 50°, the expected number of hot dogs sold would be 23.
(b)If the vendor sold 35 hot dogs, the temperature is expected to be ___degrees.
If y=35
Multiply both sides by 10/3
If the vendor sold 35 hot dogs, the temperature is expected to be 90 degrees.
(c) Based on the line of best fit, for every 10-degree increase in temperature, she should sell 3 more hot dogs.
Answer: C)
Step-by-step explanation:
The given formula :
To rearrange the formula to find the formula for r , first we multiply both sides with (a-r), we get
Divide both sides by S , we get
Subtract a on both sides , we get
Multiplying (-1) on both sides , we get
Hence, the correct answer is : C)
