The correct answer is option C which is 230p – 1010 = 650p – 400 – p this expression is same as of 2.3p – 10.1 = 6.5p – 4 – 0.01p.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given expression:-
2.3p – 10.1 = 6.5p – 4 – 0.01p
The same expression will be calculated as:-
Multiply the given expression by 100 we will get our answer.
E = 100 (s 2.3p – 10.1 = 6.5p – 4 – 0.01p )
E = 230p – 1010 = 650p – 400 – p
Therefore the correct answer is option C which is 230p – 1010 = 650p – 400 – p this expression is same as of 2.3p – 10.1 = 6.5p – 4 – 0.01p.

A school is watching students as they enter the football game for students who are dressed
inappropriately. they estimate that 7% of all students are dressed inappropriately. out of a group
of 40 students, what is the probability that exactly 2 are dressed inappropriately? round to 3 decimal places.
Using the binomial distribution, it is found that there is a 0.242 = 24.2% probability that exactly 2 are dressed inappropriately.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.The values of the parameters are given as follows:
n = 40, p = 0.07.
The probability that exactly 2 are dressed inappropriately is given by P(X = 2), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{40,2}.(0.07)^{2}.(0.93)^{38} = 0.242[/tex]
0.242 = 24.2% probability that exactly 2 are dressed inappropriately.

OC) (4,8)
OD) (-2,-1)
Answer:
C : (4,8)
Step-by-step explanation:
The equation y = (1/2) x
Or, 2y = x ==> x = 2y
means that, for any value of x, the y value must be one-half that value or, in other words, for any value of y, x must be twice the value of y
A, B and D will satisfy the above equation if you plug in values of x and y given
In C we have x = 4 and y =8 so x = y/2 NOT 2y

b = -3
c = -2
Step-by-step explanation:
The standard form of a quadratic equation:
ax² + bx + c = 0
…………………………
in order to determine the equation
in standard form ,we have to expand the given expression :
(2x + 1)(x - 2) = 2x² - 4x + x - 2
= 2x² - (4x - x) - 2
= 2x² - 3x - 2

PLEASE HELP ME WITH THIS MATH PROBLEM!!
Step-by-step explanation:
in general we would need a probabilty table or a probability calculator service on the internet.
but in this case we know.
the man value is 64. and the standard deviation is 6.
so, one standard deviation +/- interval from the mean value is 70 and 58.
and the interval of 2 standard deviations from the mean value is 76 and 52.
and 64 and 76 are exactly the limits we are asked for.
so, remember the normal distribution rule :
68% are within 1 standard deviation.
95% are within 2 standard deviations.
99.7% are within 3 standard deviations.
and 50% are below (and also above) the mean value.
so, we know, 50% of the 350 (= 175) students scored below 64.
95% of the students scored between 76 and 52. as there are 5% left, half of these 5% (= 2.5%) scored even below 52).
so, 95% + 2.5% = 97.5% of the 350 (= 341.25) students scored below 76.
therefore, the number of students that scored between 64 and 76 is
341.25 - 175 = 166.25 ≈ 166

Two friends, Vani and Shaquana, took summer jobs. The equation y=28.8xy=28.8x represents Vani's earnings in dollars and cents, yy, for working xx hours. Shaquana earned $653.40 in 33 hours.
How much less per hour does Shaquana earn than Vani?
An equation is formed of two equal expressions. Shaquana earns $10 less per hour than Vani.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation y=28.8x represents Vani's earnings in dollars and cents, y, for working x hours.
y = 28.8x
y/x = 28.8
Hence, Vani is paid $28.8 per hour.
The amount that Shaquana earned was $653.40 in 33 hours. Therefore, per hour she was paid
Amount per hour = $653.40/33 = $19.8 per hour
The difference between the two is,
Difference = $28.8 - $19.8 = $10
Hence, Shaquana earns $10 less per hour than Vani.

In the diagram below, Θ is measured in radians. Which equation represents the relationship between the radius, r, and arc length, s?
Circle O is shown. Line segments A O and B O are radii with length r. Angle A O B has a measure of theta. Arc A B has a measure of s.
s = Θ · r
r = Θ · s
s = Θ + r
r = Θ + s
The equation that represents the relationship between the radius, r, and arc length, s is s = Θ * r
How to determine the arc length?The attached image completes the question
The given parameters are:
Angle = ΘRadius = rSince, the angle is in radians.
The arc length is calculated as:
Arc length = Angle * Radius
So, we have:
s = Θ * r
