Answer:The difference between the medians is 2.5
Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5
Answer:
h(-8) = -18
Step-by-step explanation:
It is given that,
h(t)=-2(t+5)^2 --------(1)
<u>To find h(-8)</u>
Substitute t = -8 in equation (1)
h(-8) = -2(-8 + 5)^2
h(-8) = -2(-3)^2
h(-8) = -2 x 9 = -18
therefore the value of h(-8) = -18
But there is no option with value h(-8) = -18
Ryan's data collection is true that Ryan did a survey he asked about qualitative data.
Given that Ryan called every school in the district to find out if they had a recycling program.
We know that there are two types of data:
Quantitative data deals with numbers and things that we can count or measure such as dimensions such as height, width, and length.
Qualitative data relating to characteristics and descriptions cannot be counted or measured, but are observable by their qualities such as smell, taste, and color.
If we ask for quantitative data, the survey will be quantitative. Data recycling means the quality of the data available.
They can ask for a yes or no answer, as in the Ryan investigation.
Hence, the correct statement about Ryan's data collection is: Ryan conducted a survey in which he asked about qualitative data.

Answer:
The mass of the second cube is about 1085.07 grams.
Step-by-step explanation:
I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.
First, find the density of this cube:
where d is density, m is mass, and v is volume.
We have one of those, but we also need volume. The volume of a cube is just:
where a is the length of a side.
The volume of this cube is 1.728cm³. Now, you can find the density;
The density of this material is about 8.68 grams per cubic centimeter.
Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:
The volume is 125cm³. Given the density and the volume, you can calculate the mass:
The mass of the second cube is about 1085.07 grams.
