The Acme Insurance company has two types of customers, careful and reckless. A careful customer has an accident during the year with a probability of 0.01. A reckless customer has an accident during the year with a probability of 0.04. 80% of the customers are careful and 20% of the customers are reckless. Suppose a randomly chosen customer has an accident this year. What is the probability that this customer is one of the careful customers
Answer:The total probability that a random person has an accident in the given year is
.8×.01+.2×.04=0.016
The portion of that which is explained by careful drivers is .8×.01=.08. Thus the answer is
.8×.01.8×.01+.2×.04=.5
Thus it is equally likely that your accident victim was careful or careless.
Speaking informally, that's because, while it's four times more likely that a randomly selected driver is careful, it is one fourth as likely that a careful driver will have an accident, and the two

what is the point-slope equation of a line with slope -5 that contains the point (6, 3)
Answer:
y - 3 = - 5(x - 6)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 5 and (a, b) = (6, 3) , then
y - 3 = - 5(x - 6)
Given :-
Slope = -5 Point = (6,3)To Find :-
The point slope form of the line .Solution :-
As we know that the point slope form of the line is ,
→ y - y1 = m ( x - x1 )
where (x1 , y1) is the point m is the slope .→ y - 3 = -5( x - 6)
Hence the required answer is y - 3 = -5( x - 6 ) .
Martha’s biweekly gross pay is $1,000. Her deductions make up 23% of her gross pay. How much is deducted from her pay for a full calendar year?

The principal of a school district money from the schools budget to three Sports Cricket track and field and Nepal in The Rage of 432 if the total is $1,800,00,how much money will go to netball?
Answer:
[tex]NetBall = \$40000[/tex]
Step-by-step explanation:
Given
Let:
[tex]C \to Cricket[/tex]
[tex]T \to Track\ n\ Field[/tex]
[tex]N \to Netball[/tex]
[tex]C:T:N = 4:3:2[/tex]
[tex]Amount = \$180000[/tex]
Required
Budget for Netball
First, calculate the total ratio
[tex]Ratio = 4 + 3 +2[/tex]
[tex]Ratio = 9[/tex]
The ratio of netball is:
[tex]N =2[/tex]
So, the budgeted amount is
[tex]NetBall = \frac{N}{Ratio} * Amount[/tex]
[tex]NetBall = \frac{2}{9} * \$180000[/tex]
[tex]NetBall = 2 * \$20000[/tex]
[tex]NetBall = \$40000[/tex]

Answer:
There are 1680 different ways four letters can be arranged.
Since you are using the permutation formula, plug in the values and solve.
P(n,r) = P(8,4)
= 8! / (8−4)!
= 1680
Spelling out LION is only one of the 1680 possible outcomes. Therefore the fraction 1/1680 would represent this probability.
P(LION) = 1/1680

How much does Juana have in liquid assets if her car is worth $5,500 and she has
$1,310 in a savings account and $683 in her checking account? (Hint: Is a car a liquid
asset?) help
Answer:
1993
Step-by-step explanation:
Something is liquid if you can easily convert it into cash
So something like a car is not liquid (because it takes time to sell the car)
but something like a checking account is liquid (because it's easy to widthdraw your money)
so we have
1310+683= 1993

Answer:
Area of his yard = 19680ft²
Fertilizer needed = 590.4 ounces
Step-by-step explanation:
Step 1 Find the area of his lawn
The question states that his lawn is a rectangle that measures 240 feet by 82 feet
To find the area of a rectangle we simply multiply the side lengths
Hence, area of his yard = 240 * 82 = 19680ft²
Step 2 find amount of fertilizer needed.
The question states that .03 ounces is used per square foot.
So to find the amount of fertilizer needed simply multiply total area by amount used per square foot.
19680 * .03 = 590.4
So we can conclude that John will need 590.4 ounces of fertilizer

63°
Step-by-step explanation:
Since CD is a diameter, this means that
arcBD = arcCD - arcCB
= 180° - 54° = 126°
We know that the inscribed angle is half the intercepted arc, therefore angle BCD is given by
angle BCD = (1/2)arcBD
= 63°

What are the center and the radius of the circle whose equation is (x-5)^2+(y+3)^2=16
CENTER : ( 5, -3)
RADIUS : 4
Answer:
Center (5,-3)
radius : 4
Step-by-step explanation:
Radius: is the square root of 16. The square root of 16 = +/- 4. Minus 4 has absolutely no meaning for a question like this so the radius is 4. Rule take the square root of the counting number on the right.
The center is the value when x - 5 =0 and y + 3 = 0
x - 5 = 0
x = 5
y + 3 = 0
y = -3

Which triangle is a translation of the gray triangle
Answer:
Triangle DEF
Step-by-step explanation:
Hi there!
A translation of a shape occurs when all the coordinates of the original image is shifted up, down, left or right by an equal value.
Triangle ABC is a reflection of the grey triangle across the y-axis. We know this because the y-axis acts like a line of symmetry between the two shapes.
Triangle DEF appears as if it's been shifted. Therefore, triangle DEF is a translation of the grey triangle.
