Yes I just know I am in highshool
Y = 7x-2
Y = 7(4) -2
Y = 28-2
Y= 26
If that's what u mean!
If I helped mark as the Brainliest! I will really apppreciate that! Thankyou !
Answer:
Given:
Mean, u = 2100
A golf magazine reports the mean gain to be $2100, while the teaching professional believes the average gain is not $2100.
Here the null and alternative hypotheses would be:
Null hypothesis:
H0: u = 2100
Alternative hypothesis:
Ha: u ≠ 2100
b) Here, given the level of significance,
as 0.10. This means that:
The probability that the null hypothesis H0 is rejected when average gain is $2100 is 0.10
Answer:
A
Step-by-step explanation:
To write the equation of the line. first calculate the slope using the slope formula.

Since the slope of this line is 0, it is horizontal and has the form y=b where b is the y-coordinate. So y = 2 is the equation. In general form, it would be y-2 = 0
X^2 + 3x = ??...I cant really understand the equation...but u would take half of the x term...and then square it
3/2 = 1.5
1.5^2 = 2.25.....so u would add 2.25 to both sides
