Plot A shows the number of hours ten girls watched television over a one-week period. Plot B shows the number of hours ten boys

watched television over the same period of time. Television Viewing Hours for a One-Week Period 2 dot plots with a number line going from 0 to 10. Plot A has 0 dots above 0, 1, and 2, 1 dot above 3, 2 above 4, 2 above 5, 2 above 6, 2 above 7, 0 above 8 and 9, and 1 above 10. Plot B has 0 dots above 0, 1, and 2, 1 dot above 3, 2 above 4, 3 above 5, 3 above 6, 1 above 7, and 0 above 8, 9, and 10. Which statement compares the shape of the dot plots? There is a gap in both plots. There is a gap in Plot A, but not in Plot B. The data is spread widely across both plots. The data is spread widely across Plot B, but not across Plot A.

Answer:

There is a gap in Plot A, but not in Plot B

Step-by-step explanation:

There is a gap in Plot A because there are 2 dots above 7 hours, 0 dots above 8 and 9 hours and 1 dot above 10 hours.

There is no gap in Plot B.

The data is spread widely across Plot A, but not across Plot B.

What is the value of h in the figure below? In this diagram, BAD ~ CBD<br> (Help ASAP)
masha68 [24]
To get the value of h we use proportionality:
ΔABC is similar to ΔADB and is similar to ΔBDC this is because they are right triangles. This implies that there corresponding sides are equal. Hence:
AD=25-16=9
using Pythagorean theorem:
c^2=a^2+b^2
then:
AB^2=(h^2+9^2)
Also:
(BC)^2=(AB)^2+(AC)^2

=25^2-(h^2+9^2)

Also:
(BC)^2=(BD)^2+(DC)^2
thus
(BC)^2=h^2+16^2
hence combing the values for (BC)^2 we get:
25^2-(h^2+9^2)=h^2+16^2
simplifying we obtain:
625-h^2-81=h^2+256
putting like terms together
625-81-256=h^2+h^2
288=2h^2
thus
h^2=144
hence
h=√144
h=12 units

True or False; In spherical geometry, there is only one equilateral triangle.
Elodia [21]

It's true. It must equal 180 degrees and the only way to accomplish that while it being an equilateral triangle is by having only one triangle! :)

The time it takes to transmit a file always depends on the file size. Suppose you transmitted 30 files, with the average size of
Ostrovityanka [42]

Answer:

Y = 0.009042 + 0.0002457X

Y = 0.1073 seconds

Step-by-step explanation:

In the given problem we have two variables: the transmission time and average size of file.

Y = transmission time

X = average file size

The linear regression model is given by

Y = a + bX

The slope b is given by

b = correlation coefficient*(SDy/SDx)

Where SDy is the standard deviation of average transmittance time and SDx is the standard deviation of average file size.

b = 0.86(0.01/35)

b = 0.0002457

The y-intercept a is given by

a = y - bx

a =  0.04 - (0.0002457)126

a = 0.04 - 0.030958

a = 0.009042

Therefore, the linear regression model is

Y = 0.009042 + 0.0002457X

Predict the time it will take to transmit a 400 Kbyte file.

Substitute X = 400 in the regression model

Y = 0.009042 + 0.0002457(400)

Y = 0.009042 + 0.09828

Y = 0.1073 seconds

Therefore, the predicted time to transmit a 400 Kbyte file is 0.1073 seconds.
