The probabilities that stock A will rise in price is 0.42 and that stock B will rise in price is 0.58. Further, if stock B rises in price, the probability that stock A will also rise in price is 0.14. a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)
Answer:
0.92
Step-by-step explanation:
a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)
P(A) = 0.42
P(B) = 0.58
P(A|B) = 0.14
Step 1
P(A|B) × P(B) = 0.14 × 0.58
= 0.0812
The probability that at least one of the stocks will rise in price
P(A) + P(B) - 0.0812
0.42 + 0.58 - 0.0812
= 1 - 0.0812
= 0.9188
Approximately to 2 decimal place = 0.92

Answer:
51
Step-by-step explanation:
68/4=17
68-17=51

How can you use the order of operation to explain why you cannot combine the variable terms before using the distributive property when solving the equation 7(x+5)-x=42
Answer:
Step-by-step explanation:
The Order of Operations is very important when simplifying expressions and equations. The Order of Operations is a standard that defines the order in which you should simplify different operations such as addition, subtraction, multiplication and division.
This standard is critical to simplifying and solving different algebra problems. Without it, two different people may interpret an equation or expression in different ways and come up with different answers. The Order of Operations is shown below.
Parentheses and Brackets -- Simplify the inside of parentheses and brackets before you deal with the exponent (if any) of the set of parentheses or remove the parentheses.
Exponents -- Simplify the exponent of a number or of a set of parentheses before you multiply, divide, add, or subtract it.
Multiplication and Division -- Simplify multiplication and division in the order that they appear from left to right.
Addition and Subtraction -- Simplify addition and subtraction in the order that they appear from left to right.
Before we begin simplifying problems using the Order of Operations, let's examine how failure to use the Order of Operations can result in a wrong answer to a problem.
Without the Order of Operations one might decide to simplify the problem working left to right. He or she would add two and five to get seven, then multiply seven by x to get a final answer of 7x. Another person might decide to make the problem a little easier by multiplying first. He or she would have first multiplied 5 by x to get 5x and then found that you can't add 2 and 5x so his or her final answer would be 2 + 5x. Without a standard like the Order of Operations, a problem can be interpreted many different ways
We cannot combine the variable terms before using the distributive property when solving the equation as it will results in wrong answer.
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
Here the expression given is :
7(x+5)-x=42

The circular opening of a vase has an inside diameter of 13.5 cm.
-13.5 c
What is the approximate area of this circular opening? (Use a = 3.14.)
Answer:
[tex]Area = 143cm^2[/tex]
Step-by-step explanation:
Given
Shape: Opening of a circular vase
[tex]Diameter =13.5cm[/tex]
[tex]\pi = 3.14[/tex]
Required
Determine the area
This opening implies a circle; hence the area will be calculated using area of a circle.
[tex]Area = \pi r^2[/tex]
Solve for radius (r)
[tex]r = \frac{d}{2}[/tex]
[tex]r = \frac{13.5\ cm}{2}[/tex]
[tex]r = 6.75\ cm[/tex]
Substitute 6.75 for r in [tex]Area = \pi r^2[/tex]
[tex]Area = 3.14 * 6.75^2[/tex]
[tex]Area = 143.06625[/tex]
[tex]Area = 143cm^2[/tex] --- Approximated

Use the number 45,897,310.
Rearrange the digits in the number so that the 9 is worth
10 times as much.
EXPLAIN your thinking on the line below your angin
Answer:
The rearrangement can be 45, 987 , 310
Step-by-step explanation:
Here, we want to rearrange the number such that 9 is worth 10 times as what it is worth presently
The value of 9 presently is 90,000
So 10 times as worth will be 10 * 90,000 = 900,000
So we can have the new arrangement as;

30 point question! WILL AWARD BRAINLIEST!
A ball is thrown across a playing field from a height of h = 5 ft above the ground at an angle of 45° to the horizontal at the speed of 20 ft/s. It can be deduced from physical principles that the path of the ball is modeled by the function
y = − (32/(20^2))x2 + x + 5
Find the horizontal distance the ball has traveled when it hits the ground. (Round your answer to one decimal place.)
Answer:
Answers are down below ;)
Step-by-step explanation:
y = − (32/(20^2))x2 + x + 5
Plug into the calculator: -32/20^2 = -.08x^2
Find the maximum height attained by the ball:
Rewrite the equation:
y= -.08x^2 + x +5
This parabola is a negative meaning that it will be maximum
to find the maximum we use the formula -b/2a
-(1)/ 2 (-.08) = -1/ -.16= 6.25
we plug 6.25 back into the equation y= -.08(6.25)^2+ (6.25) +5 = 8.125
The maximum height attained by the ball: 8.125 feet
Find the horizontal distance the ball has traveled when it hits the ground.
This can be found with the quadratic equation, x = [-b ± √(b2-4ac)]/2a
a= -.08 , -b= -1, c= 5 (When you are plugging in the numbers, make sure to break them down).
-(-1)± √(-1)^2-4(-.08)(5)] 2(-.08) -->
[-1 ± √(1 + 1.28)]/-.16 = [-1 ± √(2.6)]/-.16 = [-1 ± 1.61]/-.16 =
The horizontal distance of the ball is x = 16.31 feet

The table represents some points on the graph of a linear function. What is the slope of the line of this function?
Answer:
-3/11
Step-by-step explanation:
using slope intercept form, y=mx+b
we know from x=0 that b=5
so we just substitute one x value m(-11)+5=8
solve for m and you get the slope
g If a snowball melts so that its surface area decreases at a rate of 8 cm 2/min, find the rate at which the diameter decreases when the diameter is 9 cm.
Step-by-step explanation:
The snowball is spherical in nature
The total surface area of the ball = 4πr²
Or 4π(d/2)²
S = 4πd²/4
S = πd²
d is the diameter of the ball
The rate at which the area is decreasing is expressed as;
dS/dt = dS/dd • dd/dt
dd/dt is the rate at which the diameter is decreasing
dS/dd = 2πd
dS/dt = 2πd • dd/dt
dS/dt = 2π(9) • dd/dt
8 = 18π•dd/dt
dd/dt = 8/18π
dd/dt = 4/9(3.14)
dd/dt = 4/28.26
dd/dt = 0.1415cm/min
Hence the diameter is decreasing at the rate of 0.1415cm/min
A regression equation for this line is y = -0.42x + 19.26 a. What do the slope and y-intercept indicate? The slope indicates that the percent in 1985 should have been about 19%. The y-intercept indicates that the percent is falling at about 0.4% each year. b. The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%. The slope indicates tha the percent has remained the same for each year. The y-intercept indicates the percent in 1985 should have been 22%. d. There is not enough information to determine what the slope and y-intercept indicate.
Answer:
B.The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%.
Step-by-step explanation:
A regression equation is it this form:
Y' = b0 + b1X
I am going to identify the slope and intercept in this equation to help us go further in our solution.
b1X is the slope. The slope usually has an x value multiplied to it
b0 is the intercept.
Back to our question, the equation in this question is
Y = -0.42X + 19.26
The slope is -0.42X.
The y intercept is 19.26
The slope has a negative sign, this shows us that the percentage is falling by about 0.4% every year while an intercept of 19.26 tells us that percentage in 1985 should have been about 19%.
I hope you found my solution useful?
