0.98 is already rounded
it may also be asking for 0.980, which is equal but shows the thousandth place

jarptica [38.1K]

Answer:

47% of American adult population

Step-by-step explanation:

The reason why polls are carried out is to obtain information that can represent the opinions, status or habits of the population. The polls do not include the total population, then include a small number of participants, but the results are extrapolated to the general population. There are always small margins of error resulting from polls, that is why the confidence levels are usually +/- 3 or 4%.

Marc is looking at the plans for his new garage. the length of the garage is 8 metres. the scale on the drawing is 1:50. what wi

evablogger [386]

The answer is 16 cm (or 0.16 m).

The scale is the ratio of the model to the real thing.
So, in the scale 1:50, the model is 1, while the real thing is 50.
Now, just make a proportion:
the model : the real thing = the model dimension : the real thing dimension
1 : 50 = x : 8m

From here:
x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.

A stone is thrown horizontally with a speed of 15 m/s from the top of a vertical cliff at the edge of a lake. If the stone hits

pishuonlain [190]

Answer:

20 m

Step-by-step explanation:

We are given that

Initial horizontal speed , $u_x=15 m/s$

Time, t=2 s

Initial vertical velocity, $u_y=0$

We know that

$h=u_yt+\frac{1}{2}gt^2$

Where $g=-9.8m/s^2$

Using the formula

$h=0(2)+\frac{1}{2}(-9.8)(2)^2$

$h=-19.6 m\approx -20 m$

The negative sign indicates that the displacement of stone is in downward direction.

Hence, the height of the cliff is closest to 20 m

Which of these points are on a line that has a slope of -3?

Ira Lisetskai [31]

Simple....

using the formula $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$ to find slope....

1.) (9,2)(4,3)

$\frac{2-3}{9-4}= -\frac{1}{5}$ (No)

2.) (9,2)(3,4)

$\frac{2-4}{9-3} = -\frac{2}{6} =- \frac{1}{3}$ (No)

3.) (2,9)(3,4)

$\frac{9-4}{2-3} = \frac{5}{-1} =-5$ (No)

4.) (2,9)(4,3)

$\frac{9-3}{2-4} = \frac{6}{-2} =-3$ (YES!)

Thus, your answer.
