What is the product of two fractions?The product of two fractions is the product of the numerators and the product of the denominators.
Product of two fractions = Product of their denominators / Product of their numerators.
Twenty hundredths = 20/100
Sixty-five thousandths = 65/1000
Product = 20/100 × 65/1000
= 2/10 × 65/1000
= 130/10000
= 13/1000
= 0.013

please help fast, will give brainliest
Answers
Answer:
1.5sin4x
Step-by-step explanation:
I just answered this question and got it right.
The function is 1.5sin(4x).
What is sin function?The ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle is the sine function in trigonometry. A right triangle's sides or unknown angles can be found using the sine function.
Given the sine function from (0, 2π), and amplitude is 1.5, the period is π/2
sine function in general form
y = a sin (b (x – h)) + d
where a = amplitude, b= period
h is the phase shift, and
d is the vertical displacement.
according to question, This function currently has no phase shift, since
h = 0, and no vertical displacement, since d = 0
equation is y = a sin b x
and b is ratio of normal period to desired period
b = 2π/(π/2)
b = 4
substitute the value of a and b in equation we get,
y = 1.5 sin (4x)
Hence the sin function from 0 to 2pi is y = 1.5 sin (4x).

−3.02. The regression line underpredicts the temperature change.
Answers
Given:
The regression equation for change in temperature, y, to amount of rain, r, is given by
[tex]\hat{y}=0.2-1.4r[/tex]
The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
To find:
The residual and interpret it.
Solution:
According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
So, the actual value is 2.3 degrees.
Put r=0.4 in the given equation, to find the predicted value.
[tex]\hat{y}=0.2-1.4(0.4)[/tex]
[tex]\hat{y}=0.2-0.56[/tex]
[tex]\hat{y}=-0.36[/tex]
We know that,
Residual = Actual value - Predicted value
[tex]Residual=2.3-(-0.36)[/tex]
[tex]Residual=2.3+0.36[/tex]
[tex]Residual=2.66[/tex]
Residual is positive because predicated value is less than the actual value.
So, the regression line underpredicts the temperature change.
Therefore, the correct option is B.

Answers
Answer:
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
Please check the attached graph.
Step-by-step explanation:
We know that:
x-coordinate of any point P(x, y) gives its distance of that point from the y-axisy-coordinate of any point P(x, y) gives its distance of that point from the x-axisGiven the points
(0.7, 21)(0.77, 10)Let us say
A(0.7, 21)B(0.77, 10)FOR POINT A(0, 7)
As the y-coordinate of point A(0.7, 21) ⇒ y = 21We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point A(0.7, 21) from the y-axis is 21 units.
i.e.
[tex]d_A=21[/tex]
FOR POINT B(0.77, 10)
As the y-coordinate of point A(0.77, 10) ⇒ y = 10We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point B(0, 7) from the y-axis is 10 units.
i.e.
[tex]d_B=10[/tex]
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
