Answer:
The average of the list of numbers is 1189.5
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
In this question:
Sum:
1049.0+1180.0+1180.1+1348.7 = 4757.8
Mean:
4 values, so:
4757.8/4 = 1189.5
The average of the list of numbers is 1189.5

Look at these figures. Which two figures have the same number of faces?
A group of 10 students are all 54 to 56 inches tall. An adult who is 74
inches tall joins the group. Which statement is true for this situation?
A None of the measures of central tendency (mean, median, or mode)
will be affected by the adult's height.
B. The median height will be more affected by the adult's height than
the mode(s) or the mean.
C. The mode(s) will be more affected by the adult's height than the
median or the mean.
D. The mean height will be more affected by the adult's height than the
mode(s) or the median.
Answer:
D. The mean height will be more affected by the adult's height than the
mode(s) or the median
Step-by-step explanation:
If you include an outlier in a set of data, its mean WILL change and get higher in this case.
The correct answer is the mean height will be more affected by the adult's height than the mode(s) or the median which is option D.
ModeSince, the mode refers to the most common number of a data set, and if the adult who is 74 inches tall joins the group of that [tex]10[/tex] students will not affect the mode as the most common height will be between 54 to 56 inches.
MedianAlso, the median refers to the middle number of a data set in ascending to descending order and if the adult joins the group of 10 students then its height will be at last and not much affect the median of the group of 10 students.
MeanNow, the mean refers to the average of a data set which is calculated by the adding the numbers and dividing the sum by the number of numbers in the data set and if the adult joins the group of 10 students then it will affect the mean of the group of 10 students as there will be a huge difference in the average when the adult joins the group.
So, accordingly, the correct option is D. The mean height will be more affected by the adult's height than the mode(s) or the median.

“The difference of 2 and a number is equal to the sum of 5 and that same number”
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
2 - x = 5 + x
Rearranging the equation, we have;
x + x = 5 - 2
2x = 3

What is the volume of a triangular prism whose base has an area of 38.2mm and heigh of the prism meausers 14mm?
Answer:
534.8
Step-by-step explanation:
Volume= area × height
= 38.2×14
= 534.8
Hence the volumer is 534.8
Answer:
534.8 mm
Step-by-step explanation:
The volume of a triangular prism is given by the relation :
Volume = Base area * height
Base area = 38.2 mm
Height = 14 mm
Hence, the Volume of triangular prism is :
V = 38.2mm² * 14mm
Volume = 534.8 mm

Cally wants to coat her driveway with a winter sealer. Her driveway is 18 feet long and shaped like a trapezoid. At the garage door, the driveway is 12 feet wide, then it widens to 20 feet at the street. How many square feet of sealer should Cally buy if she wants to apply two coats?
Answer:
Amount of Winter sealer for 2 coats[in square feet] = 576 square feet
Step-by-step explanation:
Given:
Length of drive way at garage door = 12 feet
Length of drive way at street = 20 feet
Length of total driveway = 18 feet
Find:
Amount of Winter sealer for 2 coats[in square feet]
Computation:
Amount of Winter sealer for 2 coats[in square feet] = 2[Area of trapezoid]
Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(Sum of parallel side)(Height)]
Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(12 + 20)(18)]
Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(32)(18)]
Amount of Winter sealer for 2 coats[in square feet] = 32 x 18
Amount of Winter sealer for 2 coats[in square feet] = 576 square feet
What's the answer for each to get 30 points!
Answer: "greater than" for each of the 4 dropdown menus
======================================================
Explanation:
Divide each value in the table by 40
You should get:
Horse = 15/40 = 0.375Cow = 12/40 = 0.300Sheep = 14/40 = 0.350Pig = 19/40 = 0.475Those decimal results are the experimental (ie empirical) probabilities. Theoretically, we should get 1/4 = 0.250 for each sticker type assuming each sticker is likely to be chosen. As you can see, each decimal value shown above is larger than the theoretical target of 0.250, so each answer is "greater than"
-----------
Here's another way to see why this is:
If we had 40 stickers total, and each animal has the same number of stickers, then we should have 40/4 = 10 stickers per animal type. But the table shows each frequency is above 10. So that must directly mean the empirical probability of picking any animal is greater than the theoretical probability.

Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples’ ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.
Answer:
subject?
Step-by-step explanation:
The inferences given can be concluded as (a) Agree, (b) Disagree, (c) Agree, (d) Disagree and (e) Disagree
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given two equations made each by Keiko and Eric. They are,
Keiko : t = -1.63a + 92.14
Eric : t = -1.05a + 80.97
(a) As the value of a increases, the value of t decreases for both of the equations.
So the first statement is true.
(b) When a = 20 and 30, t = 59.54 and 43.24 in the equation of Keiko.
When a = 20 and 30, t = 59.97 and 49.47 in the equation of Eric.
On an average, Eric's equation gives more t.
So second statement is false.
(c) t = 92.14 and t = 80.97 when a = 0.
A person with 0 years old cannot end texts.
So y intercept does not have a relevant meaning.
So c is also true.
(d) -1.63 and -1.05 is the slope of the corresponding lines.
This means that for every 1 year increase in age, the number of text messages decreased by 1.63.
So this is false.
(e) Similarly, in case of Eric's equation, for very 1 year increase in age, the number of text messages decreased by 1.05.
This is also false.
Hence the inferences are either agreed or disagreed as explained.

a marrow plants 0.5 m long. every week it grows by 20%. a find the value of the common ratio. b calculate how long the plant is after 12 weeks. e comment on the predicted length of the marrow after one year.
Answer:
The common ratio is 1.2.
After 12 weeks the plant will be 4.46 meters long.
After one year the plant will be 6,552.32 meters long.
Step-by-step explanation:
Given that a marrow plants 0.5 m long and every week it grows by 20%, to find the value of the common ratio, calculate how long the plant is after 12 weeks and comment on the predicted length of the marrow after one year must be performed the following calculations:
0.50 x 1.2 ^ X = Y
Therefore, the common ratio is 1.2.
0.50 x 1.2 ^ 12 = Y
0.50 x 8.916 = Y
4.4580 = Y
Therefore, after 12 weeks the plant will be 4.46 meters long.
0.50 x 1.2 ^ 52 = Y
0.50 x 13,104.63 = Y
6,552.32 = Y
Therefore, after one year the plant will be 6,552.32 meters long.
