Here it states that 62% of them go on vacations. If 2 people are selected, each one ( technically ) has a 62/100 chance of going on a vacation. So the chance that one goes on vacation and one doesn't is .62 * .38 or .2356. The chance that none of them go on vacation is 0.38 * 0.38 or 0.1444.

a/b - c + d if a = 7/8, b= -7/16, c= 0.8 and d= 1/4 write your answer as a mixed number in simplest form? help me please
Answers
a/b - c + d = (7/8) / (-7/16) - 0.8 + 1/4
We can simplify the first term by dividing the numerator by the denominator and multiplying by the reciprocal:
(7/8) / (-7/16) = (7/8) * (-16/7) = -2
Substituting this value, along with the values of c and d, we get:
a/b - c + d = -2 - 0.8 + 1/4
Combining the constant terms, we get:
a/b - c + d = -2.8 + 1/4
To express this as a mixed number in simplest form, we first convert the decimal to a fraction by multiplying both the numerator and denominator by 100:
-2.8 + 1/4 = -280/100 + 25/100
Combining these fractions, we get:
-280/100 + 25/100 = -255/100
To express this as a mixed number, we divide the numerator by the denominator to get the whole number part, and express the remainder as a fraction of the denominator:
-255/100 = -2 55/100 = -2 11/20
Therefore, the answer in mixed number form is -2 11/20.

There is concern that increased industrialization may be increasing the mineral content of river water. Ten years ago, the silicon content of the water in a certain river was 5 mg/L. Eighty-five water samples taken recently from the river have mean silicon content 5.4 mg/L and standard deviation 1.2 mg/L. a. Find the P-value. b. Do you believe it is plausible that the silicon content of the water is no greater than it was 10 years ago
Answers
Answer:
a) P value = 0.0013
b) No, it is not plausible that the silicon content of the water is no greater than it was 10 years ago
Step-by-step explanation:
The null hypothesis here is “Mean is equal to 5” while alternate hypothesis is that “Mean is greater than 5”
Given
Mean = 5, x’ = 5.4 and sigma = 1.2 and n = 85
Z = x-u’/sigma/sqrt n
Substituting the given values, we get –
Z = 3.02
A) P value = 0.0013 which is less than 0.05 and thus we will reject the null hypothesis
B) There is enough evidence to reject the null hypothesis

P=parenthesis. There isnt anything in a parenthesis, the parenthesis here are for multiplication.
E=exponents. no exponents.
M=multiplication. we have that so do that first.
5(9) and 70(6) that equals 45 and 420. now the equation is
45 + 420 - 79 + 31 + 1 - 210 - 208
D=Division. no division
A=Addition
S=subtraction. there is both. go left to right.
45 + 420 =465. now the equation is 465 - 79 + 31 + 1 - 210 - 208
465 - 79 = 386. now the equation is 386 + 31 + 1 - 210 - 208
386 + 31 = 417. now the equation is 417 + 1 - 210 - 208
417 + 1 = 418. now the equation is 418 - 210 - 208
418 - 210 = 208. now the equation is 208 - 208
208 - 208 = 0. Therefore 5(9) + 70(6) - 79 + 31 + 1 - 210 - 208 = 0

Assuming you want x to approach negative infinity, you have the correct answer. It is choice A.
=====================================================
Explanation:
The root x = -2 leads to the factor x+2. That means the answer is between A and B.
As x approaches negative infinity, i.e. as we move to the left, we're going down the red curve and y = f(x) is going to approach negative infinity as well.
In terms of symbols, we'd write \(x \to -\infty, \ f(x) \to -\infty\)
Informally, we could say "it falls to the left" as a way to describe this left end behavior.

Answers
The coefficient of the second term, 6x⁴, is 6.
The terms of the polynomial are:
-4y⁵, 6x⁴, 9w³, -4w, -1
The coefficient of the second term, which is 6x⁴, we look at the number in front of the variable term.
The coefficient is 6.
Therefore, the list of terms is:
-4y⁵, 6x⁴, 9w³, -4w, -1
Each term represents a separate component of the polynomial, where the variable is raised to a certain power and multiplied by its coefficient.
The coefficients indicate the scalar value by which each term is multiplied.
The polynomial's terms are -4y5, 6x4, 9w3, -4w, and -1.
Looking at the number in front of the variable term, we can determine the second term's coefficient, which is 6x4.
There is a 6 coefficient.
As a result, the terms are as follows: -4y5, 6x4, 9w3, -4w, and -1.
Each term represents a different part of the polynomial, where the variable is multiplied by its coefficient and raised to a given power.
The scalar value by which each phrase is multiplied is shown by the coefficients.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle.
2x + y2 = 48, x = y
Find the area of the region.
Answers
Answer: A = 58
Step-by-step explanation: The sketched region enclosed by the curves and the approximating rectangle are shown in the attachment.
From the sketches, the area will be integrated with respect to y.
To calculate the integral, first determine the limits, which will be the points where both curves meet.
In respect to y:
\(2x+y^{2} = 48\)
\(2x= 48- y^{2}\)
\(x= 24 - \frac{y^{2}}{2}\)
Finding limits:
\(y= 24 - \frac{y^{2}}{2}\)
\(24 - \frac{y^{2}}{2}-y=0\)
Multiply by 2 to facilitate calculations:
\(48 - y^{2}-2y=0\)
Resolving quadratic equation:
\(y=\frac{-2+\sqrt{2^{2}+192} }{2}\)
y = 6 and y = -8
Then, integral to calculate area will be with limits -8<y<6:
\(A = \int {24-\frac{y^{2}}{2}-y } \, dy\)
\(A = 24y - \frac{y^{3}}{6}-\frac{y^{2}}{2}\)
\(A = 24.6 - \frac{6^{3}}{6}-\frac{6^{2}}{2}-[24.(-8) - \frac{(-8)^{3}}{6}-\frac{(-8)^{2}}{2}]\)
A = 58

The volume of a cuboid is 540cm³. The length is 6cm and the width is 150mm. Work out the height of the cuboid in cm.
Answers
Step-by-step explanation:
To work out the height of the cuboid, we need to use the formula:
Volume = Length x Width x Height
We have been given the volume and the length, so we can substitute those values into the formula:
540 = 6 x Width x Height
Now we need to convert the width from millimeters to centimeters, so we divide it by 10:
150mm ÷ 10 = 15cm
Substituting this value into the formula:
540 = 6 x 15 x Height
Simplifying:
540 = 90 x Height
Dividing both sides by 90:
6 = Height
Therefore, the height of the cuboid is 6cm.

Which expression can be used to determine how much Nicole and her friend each paid for the apples?
Answers
6 pounds * $1.50 per pound = $9
Then, we can subtract the discount:
$9 - $2 = $7
Since Nicole and her friend split the cost evenly, we can divide $7 by 2:
$7 / 2 = $3.50
Therefore, each of them paid $3.50 for the apples.
The expression that can be used to determine this is:
($6 * $1.50 - $2) / 2 = $3.50
where $6 is the total cost of 6 pounds of apples at $1.50 per pound and $2 is the discount

The ship's cruising speed in calm water is 50 km/h. For the same route of 60 km, when the ship sails against the current it takes 0.5 hours more time than when sailing with the current. What was the speed of the current?
Answers
Step-by-step explanation:
Let the speed of the current be c km/h.
When the ship sails with the current, its effective speed is (50 + c) km/h.
When the ship sails against the current, its effective speed is (50 - c) km/h.
We know that the distance traveled is the same in both cases, which is 60 km.
Let's use the formula:
time = distance / speed
When sailing with the current, the time taken is:
60 / (50 + c)
When sailing against the current, the time taken is:
60 / (50 - c)
We know that when sailing against the current, it takes 0.5 hours more time than when sailing with the current:
60 / (50 - c) = 60 / (50 + c) + 0.5
Simplifying the equation, we get:
60(50 + c) = 60(50 - c) + 0.5(50^2 - c^2)
3000 + 60c = 3000 - 60c + 1250 - 0.5c^2
Simplifying further,
120c = 1250 - 0.5c^2
0.5c^2 + 120c - 1250 = 0
Solving the quadratic equation by factoring or using the quadratic formula, we get:
c = 10 km/h (ignoring the negative root)
Therefore, the speed of the current is 10 km/h.

millimeters. Determine the total number of color-wheel size combinations.
(This is probability and I’m having such a hell of a time figuring it out pls help)
Answers
There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.
To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.
Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:
Total combinations = Number of color options × Number of wheel size options
Total combinations = 4 colors × 2 wheel sizes
Total combinations = 8
