Answer:
y = 4x + 7
Step-by-step explanation:
the equation for a line is y = mx+b
the y intercept is (0,7)
so in the equation x= 0 and y= 7 and the slope is m, thus m= 4
7= (4)(0)+b
now solve for b
7 = 0 +b
7= b
so the equation of the line would be without the x and y points
y = 4x + 7
If you're talking about #3, then the equation would be 10+12.50h=5+15h.
h will equal 2, and the cost for that number of hours would then be $35.
Answer:
just subtract the area of the rectangle from the area of the carpet
fine I'll do it
Area of a rectangle= lb
Area of a square= a^2
Area of the remaining area= lb - a^2
= (12*4) - (2*2)
= 48-4
= 44 ft^2
3/5 of 1/6 is written as
3/5 x 1/6
Multiply both the numerator and denominators together:
3x1 / 5*6 = 3/30, reduces to 1/10.
The answer is 1/10.
The survey was intended for Bill's middle school during the summer. The
survey was administered to students of other schools on a Saturday.
- The type of error is the <u>selection bias error</u>.
Reasons:
The type of error made is a non sampling error, given that the target of the
study is the number of times in a week students at his middle school
attend the beach during the summer.
The errors are; Selection bias error.
- The given that the students survey are not from his middle school.
- The survey was carried out once on a Saturday, where the target was during the summer.
The selection bias error is a type error that is due to the researcher
chooses what to study, such that the participant have common
characteristics rather than being random.
