Usha thinks that the area of the development will be greater than the total area of 50 football pitches.
Usha knows
• a football pitch is rectangular 100m by 50m
• 1 mile = 1600m.
Answer:
Usha is correct
Step-by-step explanation:
See attachment
Given
Dimension of the development
[tex]Height = \frac{1}{2}\ mile[/tex]
[tex]Base = \frac{1}{2}\ mile[/tex]
Dimension of a football field
[tex]Length = 100m[/tex]
[tex]Width = 50m[/tex]
First, we calculate the area of the development.
Because it is triangular in shape, the area is:
[tex]Area = \frac{1}{2} * Height * Base[/tex]
[tex]Area = \frac{1}{2} * \frac{1}{2}mile * \frac{1}{2}mile[/tex]
Convert mile to meter
[tex]Area = \frac{1}{2} * \frac{1}{2}* 1600m * \frac{1}{2} * 1600m[/tex]
[tex]Area = \frac{1}{2} * 800m * 800m[/tex]
[tex]Area = 400m * 800m[/tex]
[tex]Area = 320000m^2[/tex]
The area of 50 football pitch is then calculated as:
[tex]Area = 50 * Length * Width[/tex]
[tex]Area = 50 * 100m * 50m[/tex]
[tex]Area = 250000m^2[/tex]
By comparison:
[tex]320000 > 250000[/tex]
Hence, Usha's thought is correct

solve each inequality below using the Addition principle. Draw a graph of each solution set.
X-7 greater than O
Answer:
x > 7
Step-by-step explanation:
Given
x - 7 greater than 0
Required
Solve as inequality and represent as a graph
greater than is represented with >
So, the equation is:
x - 7 > 0
Add 7 to both sides
x - 7 + 7 > 0 + 7
x > 0 + 7
x > 7
Next, the inequality is represented on a graph.
See attachment for graph
The shaded part of the graph represents the solution to the graph.

Answer:
y = -1/3x + 3 2/3
Step-by-step explanation:
step 1. find the slope of the given line
y2-y1/x2-x1 2 - 4/ 3 + 3 = - 1 / 3
take the opposite of that and there is your slope
step 2. plug in the values to the following equation using the given point:
y - y1 = m ( x - x1 ) y - 4 = - 1/3 ( x + 1 )
step 3. solve for y
y-4 = -1/3(x+1)
-1/3(x) and -1/3(1) ----> y-4 = -1/3x-1/3
y-4+4 = -1/3x-1/3+4 ----> y = -1/3x + 3 2/3

Answer:
232/15 [as an improper fraction] or 15 7/15 [as a mixed fraction]
Explanation:
16 - 8 / 15 =
(16) - (8 / 15) =
((16 × 15) / 15) - ((8) / 15) =
((240) / 15) - ((8) / 15) =
(240 - 8) / 15 =
232 / 15 =

Six ninth-grade students and six 12th-grade students were asked: How many movies have you seen this month? Here are their responses.
Ninth-grade students: 5,1, 2, 5, 3,8
12th-grade students: 4,2,0, 2, 3, 1
a. By hand, calculate the mean, variance, and standard deviation of each of these data sets. Which is more spread out, the ninth-grade or 12th-grade data set?
b. Make a graph of both data sets. Which of these data sets appears more spread out? Does your answer agree with your conclusion in part (a)?
Answer:
Following are the solution to the given point:
Step-by-step explanation:
Grade of students:
Grade of student:
In point a:
Grade of [tex]9^{th}[/tex] students:
[tex]\to n= 6\\\\\to Mean = \frac{ \sum x_i}{n} \\\\[/tex]
[tex]= \frac{ 5+1+2+5+2+8}{6}\\\\ = \frac{24}{6}\\\\ = 4[/tex]
[tex]\to Variance\\\\\sigma^2 = \frac{\sum(x_i -\bar{x})^2}{n-1}[/tex]
[tex]=\frac{1}{5}(10)\\\\=2[/tex]
[tex]\to Standard \ deviation ( \sigma) :\\\\= \sqrt{\sigma^2}\\\\= \sqrt{2}\\\\= 1.141[/tex]
Since the Grade of [tex]9^{th}[/tex] student's variance is higher than [tex]12^{th}[/tex]grade,
In point b:

The plot above shows that the student of the ninth grade is spread more widely, as the student from 0-8 to 12 is from 0-4.
5. Viruses spread at an exponential rate. Write a model for a virus that starts with 1 person and increases by 400% every week. Write an exponential model in the form y=ab^x to represent this situation.
Answer:
y = 4^xStep-by-step explanation:
Initial number is 1 so a = 1
Weekly growth rate is 400% which is 4 times increase, therefore b = 4
So the function becomes:

Assume that when adults with smartphones are randomly​ selected, 63​% use them in meetings or classes. If adult smartphone users are randomly​ selected, find the probability that exactly of them use their smartphones in meetings or classes.
Answer:
Solved using binomial, probability = 5.7%
Step-by-step explanation:
Number of people (N) = 7
Probability of success (using phone) = 63% = 0.63
So, probability of failure (not using phone) = 1 - 0.63 = 37
Number of success (r) = 2
N c r . P^r . Q^n-r
7 c 2 (0.63)^2 (0.37)^5
= 21 (0.3969) (0.0069)
= 0.057
