Answer:
($0.5 x 2) + ($1.25 x 3) + ($0.75 x 3) = $7
Answer: ($0.5*2) + ($1.25*3) + ($0.75*3) = $7
Step-by-step explanation: Since Laurie orders 2 fruit, 3 drinks, and 3 popcorn, we multiply the cost of each item by the number of items purchased.
For example, one fruit costs $.50. Since Laurie orders 2 fruits, we multiply .50 by 2, to get $1.
For future reference, the equation representing this problem would be
.50f+.75p+1.25d=c(total cost).

Which of the following values are possible probabilities an event will happen?
a. -2
b. 3/2
c. 1/2
d. 3
Answer:
I think the answer would be 1/2
Answer:
1/2
Step-by-step explanation:
-2 and 3 are out of the equation because they do not represent chance, 3/2 is out of the equation because the question says it has to be a possibility and 3/2 means it WILL happen, but 1/2 is a possibility that it could and could not happen. Hope I helped!

Which of the following is equivalent to x/x^2-1 + 4/x^2-6x-7?
a. x(x-7)+4(x-1)/(x+1)^2(x-7)
b. x+4/(x+1)^2(x-7)
c. x(x-7)+4(x-1)/(x+1)(x-1)(x-7)
d. x+4/(x+1)(x-1)(x-7)
Answer:
x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
Step-by-step explanation:
Given the expression x/x²-1 + 4/x²-6x-7
Factorize x²-6x-7
x²-6x-7
= x²-7x+x-7
= x(x-7)+1(x-7)
= (x+1)(x-7)
Replace back into the expression given
x/x²-1 + 4/x²-6x-7
= x/x²-1 + 4/ (x+1)(x-7)
= x/(x+1)(x-1) + 4/(x+1)(x-7)
Find the LCM
= x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
This gives the required expression

What is the slope of the line?
Answer:
4
Step-by-step explanation:
slope, m = (y₂ - y₁)/(x₂ - x₁)
plug in the values, and we get m = (3 - (-1))/((3 - 2) = 4
As x increases by 1, y increases by 4.
-1
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
find the value of n so that the system below has no solution y=nx-3
y=-4x+3
Answer:
n = - 4Step-by-step explanation:
The system of linear equations has no solution when the lines are parallel. It means the lines have same slope but different y-intercepts.
The y-intercepts are different:
-3 and 3, and the slope of one line is -4.For the given system to have no solution we need n = -4.
You want to know the mean number of sick days taken by students in your county last year. At each of five schools you randomly survey ten students. Your results are shown. Use all five samples to make one estimate for the mean number sick days taken by students in your county last year.
A: 0, 1, 1, 3, 0, 3, 0, 2, 3, 4
B: 0, 0, 0, 5, 21, 6, 8, 1, 2, 4
C: 11, 8, 1, 1, 0, 0, 4, 4, 4, 6
D: 8, 0, 10, 8, 6, 7, 9, 2, 1, 1
E: 2, 4, 5, 0, 5, 0, 5, 4, 0, 20
___ Days?
Answer:
4
Step-by-step explanation:
Add each sample separately
A.17 B. 47 C. 39 D. 52 E. 45
Then you add them all together which totals 200 sick days
We know that they surveyed 5 schools and 10 students at random from each one. So we want to know the mean of sick days the students took not the schools in all.
So we divide 200/50
And get a mean of 4.
So each student took an average of 4 sick days each in the country.

Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27

Find the expected value of the winnings
from a game that has the following
payout probability distribution:
Payout ($)| 0
2
4
6
10
Probability 0.5 0.2 0.15 0.1 0.05
Expected Value = [?]
0*.5+2*.2+4*.15+6*.1+10*.05= 2.1
The expected value of the winnings from a game is 2.1.
What is expected value?Expected value is used when we want to calculate the mean of a probability distribution. The weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value.
For the given situation,
Payouts, x = 0, 2, 4, 6, 10
Probabilities, P(x) = 0.5, 0.2, 0.15, 0.1, 0.05
The formula of expected value is [tex]E ( X ) = \mu = \sum [xP( x )][/tex]
⇒ [tex]E(X)=(0)(0.5)+(2)(0.2)+(4)(0.15)+(6)(0.1)+(10)(0.05)[/tex]
⇒ [tex]E(X)=0+0.4+0.6+0.6+0.5[/tex]
⇒ [tex]E(X)=2.1[/tex]
Hence we can conclude that the expected value of the winnings from a game is 2.1.

Find the exact value of sin 0 if cos 0=-2/3 and 90º < 0 < 180°
Answer:
sin (theta) = [tex]\frac{\sqrt{5} }{3}[/tex]
Step-by-step explanation:
cos = adjacent side/hypotenuse
Then, in a right triangle the adjacent = 2 and the hypotenuse = 3
By the Pythagorean theorem, 3^2 = 2^2 + opposite side^2
9 - 4 = 5
opposite side = [tex]\sqrt{5}\\[/tex]
sin (theta) = [tex]\frac{\sqrt{5} }{3}[/tex]
An easier way is to find sin(arccos (-2/3) = [tex]\frac{\sqrt{5} }{3}[/tex]
Note: Remember that the sin is positive in the 2nd quadrant.
