Answer:
Y = - 12.55X1 + 276.52
Step-by-step explanation:
Given the data:
Age of child :(X) : 4, 6, 10, 13, 14, 17
Time (seconds) (Y) : 230, 205, 132, 119, 108, 62
Using technology, the linear regression equation obtained using the data Given is :
Y = - 12.55X1 + 276.52
Where :
Slope = - 12.55
Intercept = 276.52
This also indicates that a negative slope is present and hence a negative relationship between age of Child and time in seconds.
Answer:
3.3 gallons
Step-by-step explanation:
(2 3/4)/x = (3 1/3)/4
(11/4)/x = (10/3)/4 (cross multiplication)
(11/4)*(4/1)=44/4=11
11/(10/3) = ( 11/1 ) * (3/10) = 33/10 = 3.3 gallons
Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
Answer:
1/4
Step-by-step explanation:
Simplify the following:
(1/6)/(2/3)
Multiply the numerator by the reciprocal of the denominator, (1/6)/(2/3) = 1/6×3/2:
3/(6×2)
3/6 = 3/(3×2) = 1/2:
1/(2×2)
2×2 = 4:

Answer:
$1.25.
Step-by-step explanation:
We have been given that at a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill.
First of all let us find how much Jasmine spent on soft pretzel and water bottle by adding the cost of both items.
To find the amount that Jasmine will get as a change we will subtract the amount spent on both items from 5.
Therefore, Jasmine will get $1.25 back as change.
