Krutika was thinking of a number. Krutika doubles it, then adds 19 to get an answer of 65. What was the original number?
Step-by-step explanation:
2x+19=65
2x+19-65
2x-46
2x=46
x=46/2
x=23
so the number is 23

A state official wants to know which party the voters in his state feel is best qualified to lead the country over the next 10 years. He mails a questionnaire on this subject to a SRS of 1600 voters in his state. His staff reports that 325 questionnaires have been returned, of these 241 respondents feel the Democratic Party is best qualified to lead the country over the next 10 years.
1. The sample is:__________
A. the voters in his state
B. the 325 questionnaires returned
C. the 241 voters who feel the Democratic Party is best qulified
D. the 1600 voters receiving the questionnaire
2. This is an example of:___________
A. a survey containing nonresponse
B. a survey with little bias because a large SRS was used
C. a survey with little bias since the voters know what they want.
D. All of the above
Answer:
1. B
2. C
Step-by-step explanation:
1. B
The sample of any set would be smaller version of a larger group. It is often a subset that contains some or all the characteristics of the main set, or the larger general population. The usage of samples comes into play in statistics when the population sizes of interest are too large for the test to contain all the needed members for it to take place. So, from this question, the sample size is the 325 questionnaires that were returned in the first place.
2. C
I thin the answer is survey with little bias since the voters know what they want. This is because while answering the survey, the voters know who they want to vote for upfront, and didn't need to gave their mind change by anyone on the survey.

The area of a rectangle is 84cm² and its breadth is 12 cm. Find its length and perimeter.
Step-by-step explanation:
A=84
b=12
l=?(l)
A=l×b
84=l×12
84/12=l
7=l
perimeter=2(l×b)
=2(7×12)

5/6 = 10/ W+3 solve for W
Answer:
[tex]\huge\boxed{w=9}[/tex]
Step-by-step explanation:
In order to solve for w here, let's write the proportion.
[tex]\frac{5}{6} = \frac{10}{w+3}[/tex]
To solve for w, we need to get it isolated on one side of the equation. To do this, we can first multiply both sides by 6 and w+3 in order to get rid of the denominators.
[tex]\frac{5}{6} \cdot 6 \cdot w+3 = \frac{10}{w+3} \cdot (w+3) \cdot6[/tex] [tex]5(w+3) = 60[/tex] [tex]5w+15 = 60[/tex] [tex]5w = 45[/tex] [tex]w = 9[/tex]Therefore, w=9.

Step-by-step explanation:
Over the next 17 months you have to read at least 68 books. You have to read x books per month.
The inequality 17x2 68 represents this situation. Solve the inequality to find the number of books
you have to read per month.
Answer:
You have to read 4 or more books per month.
Step-by-step explanation:
Given that:
Number of months to read the books = 17 months
Number of books to read = 68 at least
Number of books per month = x
The inequality for the situation is;
[tex]17x\geq 68[/tex]
Dividing both sides by 17
[tex]\frac{17x}{17}\geq \frac{68}{17}[/tex]
x ≥ 4
Hence,
You have to read 4 or more books per month.

A ball is thrown with an initial speed of 17 mph in a direction that makes an angle of 22 degrees with the positive x-axis. Express the velocity vector v in terms of i and j.
Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;
[tex]V_x = Vcos\theta\\\\V_x = 17cos(22)\\\\V_x = 15.76 \ i[/tex]
The vertical component of the velocity is calculated as;
[tex]V_y = Vsin\theta\\\\V_y = 17sin(22)\\\\V_y = 6.37 \ j[/tex]
Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)

If a circle has a diameter of 24 inches, which expression gives its area in
square inches?
O A. 12.
O B. 242.17
O C. 24. 1
O D. 122.77
Answer:
D. 12²•π
Step-by-step explanation:
Area of a circle = πr²
Radius (r) = ½ of diameter = ½*24 = 12 inches
Plug in the value into the area
Area = π * (12)²
Area = π * 12²
Area = 12²•π

please help! stuck on this question
Answer:
Center (h,k) = (4,7) and radius r = 7
Step-by-step explanation:
Explanation
Given that the equation of the circle
( x-4)² + (y-7)² = 49
( x-4)² + (y-7)² = 7²
Comparing the standard circle equation
(x-h)²+(y-k)² = r²
Center (h,k) = (4,7) and radius r = 7
