Answer:
Incorrect
Step-by-step explanation:
This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.
or 98% of the laptop have screen size between 19.2 and 21.4 inches
However, the interpretation would have been correct if it would have stated as - Value of the population mean i.e mean size of the laptop screen lies within the confidence interval.
To find out is 3/20 is larger than 2 we will convert 3/20 to a decimal. Lets do it:-
3/20
3 ÷ 20 = 0.15
Is 0.15 larger than 2?
No, 0.15 is not larger than 2.
So, 3/20 isn't larger than 2.
Hope I helped ya!! xD
The first bubble is the answer
Answer:
1.
Step-by-step explanation:
1. sin 241 = sin(61 + π) = -sin61 = -t^(1/2)
2. sin^2 + cos^2 =1, cos 61= (1-t)^(1/2)
3. [2sin^2 (x)sin(x) +2cos^2 (x)sin(x)]/2cos(x) = 2sin(x) / 2cos(x) = tan(x)
4. tan (x), x do not equal to （π/2 +or- kπ）
x do not equal to 90，270。
1. I would call quadrants i, ii, iii, iv as a, b, c, d
<span>2.Which type of variables are usually on the y-axis and represent output?
</span>they usually are the dependent variables, that is, they depend on the x value, such as velocity, price, income.
3.Which type of variables are usually on the x-axis and represent input?
those are the independent variables such as time, distance, price.
<span>4.Which type of slope is represented on a graph as a horizontal line? </span>
the slope of an horizontal line is zero.
<span>5.Find the slope of 2x + 4y = 12
</span>the general form of the line is:
4y = - 2x + 12
y = -(1/2)x + 3
hence the slope is -1/2
