Find the value of x for the given equation : 2 (x-1) - 6 =24
Answer:
x = 16
Step-by-step explanation:
2(x - 1) - 6 = 24 ( add 6 to both sides )
2(x - 1) = 30 ( divide both sides by 2 )
x - 1 = 15 ( add 1 to both sides )
x = 16

The grades of a science test are normally distributed. Thanh finds that his grade on the test has a z-score of –2.5. Which of the following statements must be true?
PLEASE SHOW WORK!
A. Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
explanation
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
with very low p values are at the ends of the normal distribution.

Check the picture below, on the left side atop
AC is a diametrical line, and thus the angle that it makes is 180°, so the arcAB is obvious. Now, the angle ADB, well is an inscribed angle touching the arcAB.
Check the picture below, on the left side below
well, that triangle is a triangle made using the diametrical AC, and thus the angle ABC is an inscribed angle in a semicircle, now check the picture on the right side
when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one.
[tex]\cfrac{x}{6}~~ = ~~\cfrac{6}{13-x}\implies 13x-x^2=36\implies 13x=x^2+36 \\\\\\ 0=x^2-13x+36\implies 0=(x-9)(x-4)\implies x=AE= \begin{cases} 9~~\checkmark\\ 4 \end{cases}[/tex]
now, let's notice something, 4 is also a valid value, why we can't use 4?
well, let's notice, the segment AE is passed the half of AC, namely passed the center, since AC is 13, half that must be 6.5, so whatever AE is, it must be greater than 6.5, so the value 4 is no dice.
3. A bag of Jelly beans contains 12 red, 17 white and 14 black jelly beans.
a) if 5 jelly beans are chosen at random, determine the probability that all 5 will be red.
Answer:
steps below
Step-by-step explanation:
Total = 12+17+14 = 43
Without replacement:
C(12,5) / C(43,5) = (12!/5!*7!) / (43!/5!*38!) = (12*11*10*9*8) / (43*42*41*40*39)
= 95040 / 115511760
= 0.00082
≈ 0.082%
with replacement: 12/43*12/43*12/43*12/43*12/43 = 12⁵ / 43⁵

If m varies directly with t, and m = 4 when t = 12, what is the value of t when m = 12?
O4
O20
O24
O36
Answer:
t = 36
Step-by-step explanation:
given that m varies directly with t then the equation relating them is
m = kt ← k is the constant of variation
to find k use the condition m = 4 when t = 12 , then
4 = 12k ( divide both sides by 12 )
[tex]\frac{4}{12}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
m = [tex]\frac{1}{3}[/tex] t ← equation of variation
when m = 12 , then
12 = [tex]\frac{1}{3}[/tex] t ( multiply both sides by 3 to clear the fraction )
36 = t

Which coordinates identify a location north of a city that has a latitude of 38. 0°n and a longitude of 25. 0°w?.
Using translation concepts, y-coordinates greater than 38 identify a location north of the city.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Considering latitude and longitude, the coordinates of a city are given as follows:
(LON, LAT).
Hence, the given city has coordinates given by:
(25, 38)
As we move north, the latitude increases, hence, y-coordinates greater than 38 identify a location north of the city.
