Step-by-step explanation:
cost price = $640
sell price = $940
percentage = ?
Rate * Base = Amount
Percent * Sell Price = Cost Price
P * 940 = 640
P940 = 640
P940/940 = 640/ 940
P = 0.66666667
Percent = (0.66666667 × 100)/100 = 66.666667
Correct Answer is 66 2/3%
Consider the function f(x) = √ x+2 and g(x) = ax+b. Find a and b, if fog (1) = 2 and g (-1)=2.
The value of a and b in the function f(x) = √ x+2 and g(x) = ax + b , is a = 0 and b = 2 .
In the question ,
it is given that ,
the function f(x) = √(x+2) and the function g(x) = ax + b
also given that
fog(1) = 2
f(g(1)) = 2
f(a + b) = 2 .... because g(1) = a + b
√(a + b +2) = 2
Squaring both the sides
a + b + 2 = 4
a + b = 2 .......(1)
also given that
g(-1) = 2
a(-1) + b = 2
-a + b = 2 .....(2)
Adding equation (1) and (2) , we get
2b = 4
b = 2
Substituting b = 2 in the a + b = 2 , we get
a + 2 = 2
a = 2 - 2
a = 0
Therefore , The value of a and b in the function f(x) = √ x+2 and g(x) = ax + b , is a = 0 and b = 2 .

A nursing administrator went through a sample of hospital records and found that, out of 500 randomly selected records, 217 of the patients had been admitted for heart issues. What is the sample statistic?
The sample statistic when the nursing administrator went through a sample of hospital records is 217.
What is statistic?A statistic is a metric used to describe a sample. Estimation or hypothesis testing can be used to determine how likely it is that a sample statistic differs from the population parameter.
A sample is an analytic subset of a larger population in statistics. The use of samples enables researchers to conduct studies with more manageable data and more quickly. Randomly drawn samples have little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.
A sample statistic is a piece of statistical data derived from a small number of items. A sample is merely a subset of a population. Therefore, the 217 of the patients had been admitted for heart issues is the sample.

What is the image point of (-6, -4) after the transformation T4.-1 ° ry=-x?
(16, 36) is the image point .
What is image point?
The provided point P is "reflected" in the mirror, appearing on the other side of the line at a distance equal to that from it. To see this, move the point P. Conventionally known as P' (pronounced "P prime"), the point P's reflection over the line is also referred to as the point P's "image."Reflecting (-6, -4) in the line y= - x yields the point (4, 6).
Dilating (4, 6) by a factor of 4 gives the point (16, 36).

One year consumers spent an average of $23 on a meal at a restaurant. Assume that the amount spent on a restaurant meal is normally distributed and that the standard deviation is $5.
A) What is the probability that a randomly selected person spent more than $25?
B) What is the probability that a randomly selected person spent between $12 and $21?
C) Between what two values, symmetrically distributed around the mean, will the middle 95% of the amounts of cash spent fall?
Using the normal distribution, it is found that:
a) The probability that a randomly selected person spent more than $25 is of 0.3446 = 34.46%.
b) The probability that a randomly selected person spent between $12 and $21 is of 0.3307 = 33.07%.
c) The middle 95% of the amounts are between $13.2 and $32.8.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for the costs of the meal are given as follows:
[tex]\mu = 23, \sigma = 5[/tex]
The probability that a randomly selected person spent more than $25 is one subtracted by the p-value of Z when X = 25, hence:
Z = (25 - 23)/5
Z = 0.4
Z = 0.4 has a p-value of 0.6554.
1 - 0.6554 = 0.3446 = 34.46%.
The probability that a randomly selected person spent between $12 and $21 is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 12, hence:
X = 21:
Z = (21 - 23)/5
Z = -0.4
Z = -0.4 has a p-value of 0.3446.
X = 12:
Z = (12 - 23)/5
Z = -2.2
Z = -2.2 has a p-value of 0.0139.
0.3446 - 0.0139 = 0.3307 = 33.07%.
The normal distribution is symmetric, meaning that the bounds of the middle 95% of values are given as follows:
2.5th percentile: X when Z = -1.96.97.5th percentile: X when Z = 1.96.-1.96 = (X - 23)/5
X - 23 = -1.96 x 5
X = $13.2
1.96 = (X - 23)/5
X - 23 = 1.96 x 5
X = $32.8

What are similar triangles?
If two triangles' corresponding angles and sides are identical and their corresponding sides are proportional, or if the ratios between the lengths of the corresponding sides are comparable, then two triangles are said to be similar.
Similar triangles are triangles with the same shape but different sizes. Examples of related objects are all equilateral triangles and squares with any side length.
The triangles ONP and LNM are similar triangles.
So, the following is true.
(ON/LN)=(NP)/(NM)
(3.6/6)=(6)/(NM) ( LN=LO+ON=2.4+3.6=6 )
3.6 NM=6*6 =36
NM=36/3.6 = 10

What is the solution to the system of equations
The solution of the given system of equations is (-1, -2).
Explain the method of substitution?Three steps make up the substitution technique: For each of the variables, solve one equation. Put this expression (or plug it in) into the other equation, then solve it. To identify the corresponding variable, rewrite the value's original equation.We are aware that a linear system of equations can be solved using a substitution method.
The intersection of the two lines represents the system's solution.
The given equations are-
y = 3x+1 ...eq 1
y = -2x-4 ...eq 2
Put the value of eq 1 in eq2 .
3x+1 = -2x-4
3x + 2x = -4 - 1
5x = -5
x = -5/5
x = -1
Put the x in eq 1.

A line intersects the points
(8, -4) and (-6, 10).
m = -1
Write an equation in point-slope form
using the point (8, -4).
-
y + 4 = [?] (x −
Enter
Answer:
y + 4 = -(x - 8)
Step-by-step explanation:
The point-slope form equation is y - y1 = m(x - x1)
Since we're given m and since they use the 4 from (8, -4) as y - (-4) = y+4, we simply need to plug in 8 into the RHS of the equation and you can check the math.
If you substitute 8 and -4 for y and x, you have:
-4 + 4 = -1(8 - 8)
0 = -1 * 0
0 = 0
You'd get -2 on both sides if you used -6 and 10, but having an equal equation means our math is true/accurate.

The option that is the graph of (g – f)(x) is; On a coordinate plane, a straight line with a positive slope goes through points (negative 2, negative 6), (0, 0), and (2, 6).
