Answer:
1.B 2.H 3. A
Step-by-step explanation:
1. First, find out the percentage of people who voted for Mathematika in survey one.
The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.
To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.
2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.
3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.
7+9+11+13+15 = 55
5 numbers were added together so you divide 55 by 5
55/5 = 11. The mean is 11
9+10+11+12+13 = 55
There were 5 numbers added together
55/5 = 11. Both the means were the same
What is the value of x?
Answer:
135°
Step-by-step explanation:
here's your solution
=> we know that , sum of all angles is
equal to 180°
=> hence ,we have two angles
=> 1st angle = 45°
=> 2nd angle = 9x + 18
=>. adding both angle
=> 45° + 9x + 18° = 180°
=> 63° + 9x = 180°
=> 9x = 180° - 63
=> 9x = 117°
=>. x = 117/9
=> x = 13°
=>. hence, the required angle = (13*7) + 18°
=> angle = 135°

The distance in miles that some students live from school is show in the histogram which stamen about the data in the histogram is true
Answer:
D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.
Step-by-step explanation:
The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.

A school board voted whether to adopt a new math text book.Those that voted yes outvoted those that voted no by a ratio of 5:1 if 18 total school board members voted in the meeting how many voted yes for new math books?
Answer:
Members that voted yes = 15 Members
Step-by-step explanation:
Members that voted yes : members that voted no = 5 : 1
Total ratio = 5 + 1 = 6
total school board members that voted = 18
how many voted yes for new math books?
Members that voted yes = 5/6 × 18
= 0.8333333333333 × 18
= 15 members
Members that voted yes = 15 Members
members that voted no = 1/6 × 18
= 0.1666666666666 × 18
= 3
members that voted no = 3 members

A random representative survey of 100 seventh-graders in Washington Middle School shows that 20 students read 5 or more books over the summer. If there are 275 seventh-graders at Washington Middle School, based on the sample results how many seventh-graders read 5 or more books last summer?
20 out of 100 read 5 or more.
20/100 = 0.2
Now multiply the total students by 0..2:
275 x 0.2 = 55
55 people read 5 or more books.

A pile of earth removed from an excavation is a cone measuring 6ft high and 30ft across its base. How many trips will it take to haul away the earth using a dump truck with a capacity of 125 cubic feet?
Answer: 14
Step-by-step explanation:
Given
Excavation cone measures
height [tex]h=6\ ft[/tex]
Diameter [tex]d=30\ ft[/tex]
Truck can dump [tex]125\ ft^3[/tex] at a time
The volume of a cone is
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Putting values
[tex]\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3[/tex]
No of trips(N) required to accumulate this much volume is given by
[tex]\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14[/tex]
Therefore, 14 trips are necessary to accumulate a cone of volume [tex]1414\ ft^3[/tex]
