Answer:
b. 0.055
Step-by-step explanation:
The point estimate of the proportion of people who wear hearing aids is
The number of people in the sample who wear hearing aids divided by the total number of people in the sample.
In this problem, we have that:
Sample of 855.
47 people in the sample had hearing aids.
47/855 = 0.0549
Rounding up
0.055
So the correct answer is:
b. 0.055
There are 90 4-digit palindromes
<h3>What are palindromes?</h3>
Palindromes are numbers whose reverse is the same as the original number
<h3>How to determine the count of 4-digit palindromes</h3>
Since the digit is 4, then
- The first digit of the palindrome can be any of 1 to 9 (i.e. 9 digits)
- The second digit can be any of 0 - 9 (i.e. 10 digits)
- The third digit must be the second digit (i.e. 1 digit)
- The last digit must be the first digit (i.e. 1 digit)
So, the total number of digits is:

Evaluate the product

Hence, there are 90 4-digit palindromes.

This has to be given by your values...in simple words the graph is an hyperbola and is given in the form F(x)=ax (to the power 2) -6
Step-by-step explanation:
THE REASON AS TO WHY -6 IS IN THE EQUATION IS BECAUSE ITS A Y INTERCEPT AND BASED ON MATH ANY NEMERICAL VARIABLE IN A FUNCTION IS THE Y-INT
THE "A" AND "X" VALUES YOU YOURSELF HAVE TO DETEREMINE,BASED ON HOW YOUR GRAPH IS.

Answer:
9) Vincent will not get the correct answer because the + 484 is unneccesary, as he already subtracted it.
10a) 310,000 + x = 465,000; so x = 155,000
10b) 930,000/310,000 = 3 times more
Step-by-step explanation:
The answer to this question is A as it is the only one with the correct slope
