Answer:
Lower limit = 0.76
Upper limit = 0.84
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 350
Number of drivers that buckle = 280
Formula:


The standard deviation for sp =

95% Confidence Interval:


Putting the values, we get,

Lower limit = 0.76
Upper limit = 0.84
Answer:
Maximum number of children among whom 32 red marbles, 144 blue marbles and 176 green marbles can be divided equally is 16.
Step-by-step explanation:
Finding HCF of 32, 144, 176
32 = 2 * 2 * 2 * 2 * 2
144 = 2 * 2 * 3 * 2 * 2 * 3
176 = 2 * 2 * 2 * 11 * 2
HCF = 2 * 2 * 2 * 2 = 16
Answer: -0.4
-(4/5) ÷2=-0.4
Explanation: The quotient is the answer to a division problem.
R is between S and T, so this implies that R is on line ST and we can say
SR+RT = ST
plug in the given expressions to get
(-2x+24)+(4x+10) = 4x+12
Now solve for x
(-2x+24)+(4x+10) = 4x+12
-2x+24+4x+10 = 4x+12
2x+34 = 4x+12
2x+34-2x = 4x+12-2x
34 = 2x+12
34-12 = 2x+12-12
22 = 2x
2x = 22
2x/2 = 22/2
x = 11
If x = 11, then RS is,
RS = -2*x+24
RS = -2*11+24
RS = -22+24
RS = 2

Answers:
x = 11 and RS = 2
Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.
Hope this helps!
