Answer:
-2
Step-by-step explanation:
-2 is two less than 0. if you add 2 to this, you get 0. if you take away 0 from 0, it is still 0. if you take away two from 0, you get -2. so the answer is -2

12. A drawer contains 2 red socks, 6 white socks,
and 4 blue socks. Without looking, you draw out a
sock, return it, and draw out a second sock. What
is the probability that the first sock is blue and the
second sock is red?
Answer:
Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Step-by-step explanation:
Number of red socks = 2
Number of white socks = 6
Number of blue socks = 4
Total socks in drawer = 2+6+4 = 12
The formula used to calculate probability is: [tex]Probability=\frac{Number \ of \ favourable \ outcomes}{Total \ number \ of \ outcomes}[/tex]
We are given you draw out a sock, return it, and draw out a second sock.
We need to find the probability that the first sock is blue and the second sock is red?
Using formula:
Probability that first sock is blue = 4/12 = 1/3 = 0.33
Probability that second sock is red = 2/12 = 1/6 = 0.16
So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16

Assume that emergency medical personnel in California are planning for future resources and it has been observed that the average number of traffic accidents requiring ambulance assistance on the Hollywood Freeway between 7 and 8 AM on Wednesday mornings is 1.1. What, then, is the probability that there need for exactly 2 ambulances on the Freeway during that time slot on any given Wednesday morning?
Answer:
Answer is 0.5
Step-by-step explanation:
The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.
The time slot and time of day remain same in both the text and the question.
The average or mean number of accidents is 1.1
QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?
In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?
Since the mean number of accidents is 1.1, 2 is above the mean.
Probability of 1.1 accidents is 1, since that's the mean (expected value).
Probability of 2 accidents is 1/2 which is = 0.5

mark is shopping during a computers store 20% sale. He wants to buy computers in the range of $500 to $1000. how much are the computers after 20%
It's £2000 ( don't have the us money sign sorry )
The cost of computer($1000) after sale is $800.
Given that, a computers store 20% sale. He wants to buy computers in the range of $500 to $1000.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
If cost of computer is $500
Then, 20% of 500 = 0.2×500
= $100
So, after sale the cost of computer is 500-100=$400
Similarly, for other cost as well
If cost of computer is $1000
Then, 20% of 1000 = 0.2×1000
= $200
So, after sale the cost of computer is 1000-200=$800
Therefore, the cost of computer($1000) after sale is $800.

Latoya finished her English assignment in 1/2 hours. Then she completed her history assignment in 2/3 hours. How much more time did Latoya spend on her history assignment?
1/6 more hours. Because 1/2 and 2/3 are equal to 3/6 and 4/6. Then you subtract and get 1/6
The time Latoya spend on completing her history assignment is given by the equation A = 1/6 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The time for Latoya to complete her English assignment = 1/2 hours
The time for Latoya to complete her History assignment = 2/3 hours
So , the difference in time = extra time for Latoya to complete history assignment
Substituting the values in the equation , we get
The difference in time A = ( 2/3 ) - ( 1/2 )
The difference in time A = ( 4 - 3 ) / 6
The difference in time A = 1/6 hours
Hence , the equation is A = 1/6 hours

The values in the table represent the graph of a continuous function. Which interval must contain an x-intercept? x y –3.1 –1.85 –2.7 –0.84 –2.3 –0.09 –1.9 0.44 –1.5 0.79 –1.1 1.00 –0.7 1.10 –0.3 1.13 0.1 1.13 –3.1 < x < –2.7 –2.3 < x < –1.9 –1.5 < x < –1.1 –0.3 < x < 0.1
Given:
The values in the table represent the graph of a continuous function.
To find:
The interval that must contain an x-intercept.
Solution:
From the given table it is clear that, initially y-values are negative but after negative values we get y=0.44 at x=-1.9.
This signs of y-value are different, it means the graph of continuous function must contain an x-intercept in the interval -2.3 < x < -1.9.
Therefore, the correct option is B.
Answer:
Its , -2.3 < x < -1.9

The cost of a pound of nails increased from $2.17 to $2.52. What is the percent of increase to the nearest whole-number percent?
Answer:
16% is the percent of increase to the nearest whole-number percent.
Step-by-step explanation:
As the cost of a pound of nails increased from $2.17 to $2.52.
$2.52 - $2.17 = $0.35so dividing the 0.35 by 2.17 would give us the percetange of increase
0.35/2.17 = 0.16 which is 16%.Therefore, 16% is the percent of increase to the nearest whole-number percent.
