Don't drink and drive: A highway safety council reported that there were 3972 fatalities among drivers in auto accidents in a particular year. Following is a frequency distribution of their ages. Approximate the mean age. Round your answer to one decimal place. Age Number of Fatalities 11-20 340 21-30 1527 31-40 866 41-50 693 51-60 423 61-70 123 Send data to Excel The mean is approximately .
Answer:
[tex]\bar x = 34.7[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{cc}{Age} & {Fatalities} & {11 - 20} & {340} & {21-30} & {1527} & {31-40} & {866} & {41-50} & {693} & {51-60} & {423} & {61-70} & {123} \ \end{array}[/tex]
Required
Calculate the mean
The given data is a grouped data. So, we need to calculate the class mid -point first.
This is done by calculating the average of the class intervals.
So, we have:
[tex]\begin{array}{ccc}{Age} & {Fatalities} & {x} & {11 - 20} & {340} & {15.5} & {21-30} & {1527} &{25.5}& {31-40} & {866} & {35.5} & {41-50} & {693} & {45.5} & {51-60} & {423} & {55.5} & {61-70} & {123} & {65.5}\ \end{array}[/tex]
For 11 - 20, the midpoint is: [tex]x =\frac{1}{2}(11+20) = \frac{1}{2}*31=15.5[/tex]
For 21 - 30, the midpoint is: [tex]x =\frac{1}{2}(21+30) = \frac{1}{2}*51=25.5[/tex]
.....
For 61 - 70, the midpoint is: [tex]x =\frac{1}{2}(61+70) = \frac{1}{2}*131=65.5[/tex]
The mean is then calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
[tex]\bar x = \frac{(15.5 * 340) + (25.5 * 1527) + (35.5 * 866) + (45.5 * 693) + (55.5 * 423) + (65.5 * 123)}{340 + 1527 + 866 + 693 + 423 + 123}[/tex]
[tex]\bar x = \frac{138016}{3972}[/tex]
[tex]\bar x = 34.7472306143[/tex]
[tex]\bar x = 34.7[/tex] --- approximated
The mean is approximately 34.7

Strands of copper wire from a manufacturer are analyzed for strength and conductivity. The results from 100 strands are as follows: Strength High Low High conductivity 74 8 Low conductivity 15 3 a. If a strand is randomly selected, what is the probability that its conductivity is high and its strength is high
Answer:
0.74
Step-by-step explanation:
Given :
__________________ STRENGTH __
__________________High _ Low
High conductivity _____ 74 __ 8
Low conductivity _____ 15 ___ 3
Probability that conductivity is high and strength is high :
This the probability of High conductivity n High strength = P(High conductivity n High strength)
Probability = required outcome / Total possible outcomes
Required outcome = P(High conductivity n High strength) = 74 (from table)
Total possible outcomes = total sample size = 100
Hence,
P(High conductivity n High strength) = 74 / 100 = 0.74
Patty buys a new car and gets it appraised every few years. After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
If Patty gets her car appraised after owning it for 6 years, what will the car's value be in this indirect variation situation?
A. $7,500
B. $2,500
C. $6,000
D. $4,000
Answer:
c) 6000
Step-by-step explanation:
the car's value would be $6000 because in two years the car decrased by $6000. Divide that by 2, and get $3000. That's how much it decreases in one year. $9000-$3000=$6000
btw I can't help it the car's original value was $24,000

Use the linear combination method to solve the system of equations. Explain each step of your solution.
2x-3y=13
2x+4y=-8
Step-by-step explanation:
Equation 1: 2x - 3y = 13
Equation 2: 2x + 4y = -8
Subtract Equation 1 from Equation 2:
2x + 4y = -8
- (2x - 3y = 13)
=> 7y = -21, y = -3.
Then 2x - 3(-3) = 13, 2x + 9 = 13, x = 2.
The solutions are x = 2 and y = -3.

The triangles are similar. Solve for x. Hint - draw the triangles separately.
Answer:
The answer is 18
Step-by-step explanation:
All you have to do is look at the length the left side of the triangle and see what you have to divide the larger number by to get the smaller number.
Then you have to divide the number on the bottom by the number that you had to divide the larger number by the side by.

Write a rule for g described by the transformation of the graph of f...
Answer:
[tex]g(x) = 4-4\sqrt{x}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4\sqrt{x}+1[/tex]
1. 5 units down translation
2. Reflection in the x-axis
Required
Determine the resulting function g
1. 5 units down translation
This is defined by the rule:
A down translation is:
[tex]f'(x) = f(x) - b[/tex]
Where b is the number of units.
So, we have:
[tex]f'(x) = 4\sqrt{x} + 1 - 5[/tex]
[tex]f'(x) = 4\sqrt{x} -4[/tex]
2. Reflection in the x-axis
For a function f(x),
When reflected over the x-axis, it becomes -f(x)
So:
[tex]g(x) = -f(x)[/tex]
[tex]g(x) = -(4\sqrt{x} - 4)[/tex]
[tex]g(x) = -4\sqrt{x} +4[/tex]
[tex]g(x) = 4-4\sqrt{x}[/tex]
What is 8/12 + A/12=2/b
Answer:
A = -4
B = 12

Solve the equations by using elimination Adding.
Answer:
The answer will be the following :
Step-by-step explanation:
Let's solve for x.
3x−2y=46x
Step 1: Add -46x to both sides.
3x−2y+−46x=46x+−46x
−43x−2y=0
Step 2: Add 2y to both sides.
−43x−2y+2y=0+2y
−43x=2y
Step 3: Divide both sides by -43.
−43x
−43
=
2y
−43
A bakery sold a total of 500 cupcakes in a day, and 83% of them were vanilla flavored. How many of the cupcakes sold that day were vanilla flavored?
Total number of vanila flavored cupcakes sold in a day by the bakery is 415.
Calculations to find the actual number from its percentage:Expression to be used,
Number of flavored cupcakes = percentage of vanila flavored
cupcakes × Total number of cupcakes sold in a day
Total number of cupcakes sold by the bakery = 500
Percentage of the cupcakes having vanilla flavor = 83%
Number of vanila flavored cupcakes = 83% of 500
= [tex]\frac{83}{100}\times 500[/tex]
= 415
Therefore, number of vanila flavored cupcakes sold by the bakery will be 415.
