Answer:
5x = 11.
Step-by-step explanation:
-4x - 2y = -2
x - 2y = 9
Subtracting:
-4x - x - 2y - (-2y) = -2 - 9
-5x - 2y + 2y = -11
-5x = -11
5x = 11.

consider a population consisting of values 2, 3, 5, 7. what is the population standard deviation?
Answer:
The population standard deviation is 1.92.
Step-by-step explanation:
Population mean:
Sum of all values divided by the number of values. Thus:
[tex]M = \frac{2 + 3 + 5 + 7}{4} = 4.25[/tex]
Population standard deviation:
Square root of the division between the sum of the difference squared of each value and the mean, and the number of values. Thus.
[tex]S = \sqrt{\frac{(2-4.25)^2 + (3-4.25)^2 + (5-4.25)^2 + (7-4.25)^2}{4}} = 1.92[/tex]
The population standard deviation is 1.92.

An airplane travels 240 miles in 3 hours with the wind. The return trip against the wind takes 4 hours. What is the wind speed and the speed of the airplane in still air?
Answer:
Let p = the speed of the plane
and w = the speed of the wind
It takes the plane 3 hours to go 600 miles when against the headwind and 2 hours to go 600 miles with the headwind. So we set up a system of equations.
600mi3hr=p−w600mi2hr=p+w
Solving for the left sides we get:
200mph = p - w
300mph = p + w
Now solve for one variable in either equation. I'll solve for x in the first equation:
200mph = p - w
Add w to both sides:
p = 200mph + w
Now we can substitute the x that we found in the first equation into the second equation so we can solve for w:
300mph = (200mph + w) + w
Combine like terms:
300mph = 200mph + 2w
Subtract 200mph on both sides:
100mph = 2w
Divide by 2:
50mph = w
So the speed of the wind is 50mph.
Now plug the value we just found back in to either equation to find the speed of the plane, I'll plug it into the first equation:
200mph = p - 50mph
Add 50mph on both sides:
250mph = p
So the speed of the plane in still air is 250mph.
Answer:
140miles/hour
Step-by-step explanation:
Speed of airplane + speed of wind
=240miles/3 hours + 240miles/4 hours
=80miles/hour +60miles/hour
= 140miles/hour

Isabel Briggs Myers was a pioneer in the study of personality types. The personality types are broadly defined according to four main preferences. Do married couples choose similar or different personality types in their mates? The following data give an indication.
Similarities and Differences in a Random Sample of 375 Married Couples
Number of Similar Preferences Number of Married Couples
 All four                     29
Three                     124
Two                     120
One                     66
None                     36  Â
Suppose that a married couple is selected at random.
Required:
Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common.
Answer:
P ( All four) = 29/375=0.07733
P ( Three A^) = 124/375= 0.33067
P ( Two A^) = 120/375= 0.32
P (One A^) = 66/375= 0.176
P (None A^) = 36/375= 0.096
Step-by-step explanation:
Number of Similar Preferences  Number of Married Couples
All four 29
Three 124
Two 120
One 66
None 36
Total 375
We want to determine the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common.
P ( All four) = 29/375=0.07733
P ( Three A^) = 124/375= 0.33067
P ( Two A^) = 120/375= 0.32
P (One A^) = 66/375= 0.176
P (None A^) = 36/375= 0.096
Probability is calculated by favorable outcome divided by the total outcome.
Similarly we obtained the probabilities of the couples that they will have 0, 1, 2, 3, or 4 personality preferences in common.

Answer:
x = 46.8
Step-by-step explanation:
I assume you are trying to find the value of x.
[tex]5x=234.[/tex]
To find x, divide the answer by the coefficient. The quotient is the value of 'x.'
[tex]234/5=46.8[/tex]
Therefore, 46.8 is the value of x.
Remember: Whenever you see a coefficient and a variable together—5x, 7y, 3t—this means to multiply them.
Cora's dad has asked Cora and her little brothers to rake the leaves in their yard. They rake all afternoon and fill a number of bags with leaves. Then, when Cora isn't looking, her brothers empty 6 of the bags to make a giant leaf pile! Cora is frustrated that only 5 bags of leaves remain. What equation can you use to find the total number of bags b that Cora and her brothers fill with leaves?
Answer:
11
Step-by-step explanation:
because they empty 6 bags and there are 5 bags left to that is 11 all together
The total number of bags of leaves b is given by the equation b = 11 bags
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
Let the total number of bags be = b
The number of bags emptied by Cora's brother = 6 bags
The number of bags left with Cora = 5 bags
So , the equation will be
The total number of bags b = number of bags emptied by Cora's brother + number of bags left with Cora
Substituting the values in the equation , we get
The total number of bags b = 6 + 5
The total number of bags b = 11 bags
Therefore , the value of A is 11 bags
Hence , the number of bags of leaves is 11 bags

A brand new car was purchased for $28,000 in year 2000. The car value has dropped to
$20,000 in year 2003. What could be considered as the rate of depreciation?
(Round your answers to the nearest 10th.)
Answer:
The rate of depreciation is 11.87% per year.
Step-by-step explanation:
Given that a brand new car was purchased for $ 28,000 in year 2000, and the car value has dropped to $ 20,000 in year 2003, to determine what could be considered as the rate of depreciation, the following calculation must be performed:
20,000 x (1 + X / 1) ^ 3 = 28,000
20,000 x X ^ 3 = 28,000
20,000X ^ 3 = 28,000
X = 1.1187
Therefore, the rate of depreciation is 11.87% per year.

It can be convenient to convert these to base 8 for comparison. (Bases 2, 4, and 8 are easily interconverted by regrouping the base-2 bits of the number.) Using periods to mark groups of bits, we have ...
1000100₂ ⇒ 1.000.100₂ ⇒ 104₈
10100₄ ⇒ 01.00.01.00.00₂ ⇒ 0.100.010.000₂ ⇒ 0420₈

When the sum of digits in a column equals or exceeds the base, then 1 is carried to the next column to the left, and the excess is written as the sum of the column. In base 2, this means 1+1 = 10. In base 4, this means 3+1=10, or 1+2+2=11.
Subtraction of a larger digit from a smaller one can be done by "borrowing" 1 (the amount of the base) from the next column to the left. In base 8, for example, this means 32-7 = 23.
These rules are identical to the rules that apply in base ten arithmetic.

Perhaps you're stuck because it is too simple. If any value in the x-column is repeated, the relation is not a function.
Of the two relations shown, the first is not a function (x=3 is repeated), and the second one is a function (all the x-values are different).
