The letters of the word COMPLEMENT are written on cards and shuffled. Find the probability that the card chosen does not have the letter M written on it.
Answer: the probability would be 1:5
Step-by-step explanation: since there are 2 m you would put that on top and divide it by all the others and there are 10 of them and then simplifie it and get the answer
Answer:
P ( not M)= 4/5
Step-by-step explanation:
We want to find the probability that if a card is chosen, it does not have the letter M on it.
The probability can be found by creating a fraction with the number of cards that do not have M over the total number of cards.
P (not M) = cards without M / total cards
The word complement has 10 letters, therefore there is a total of 10 cards.
P (not M) = cards without M/ 10
There are 2 cards with an M. That will leave 8 cards without an M. (10 total cards - 2 cards with M= 8 cards without M).
P (not M)= 8/10
This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 2.
P (not M)= (8/2) / (10/2)
P (not M)= 4/ (10/2)
P (not M) = 4/5
The probability of choosing a card without the letter M on it is 4/5

A researcher conducted a survey to 50 respondents about what they like among the three online games, namely the mobile legends, the clash of clans, and the player's unknown battlegrounds (PUBG) out of 50 respondents, 15 people chose PUBG, 30 chose mobile legends and 20 chose clash of clans, How many Respondents chose all 3 online games?
Answer:
15 Respondents
Step-by-step explanation:
Total number of respondents = n (PUBG ∪ M ∪ C) = 50
PUBG = n(PUBG ) = 15 people
Mobile legends = n(M) = 30 people
Clash of clans = n(C) = 20 people
n ( PUBG ∩ M) = Unknown
Step 1
The first step is to find the number of respondents that chose two or the games
a) Number of respondents that chose Mobile legends and PUBG =
n ( M ∩ PUBG)
30 - x = 15 - x + x
30 - 15 = x + x - x
15 = x
b) a) Number of respondents that chose Mobile legends and Clash of clans =
n ( M ∩ C)
n ( M ∩ C) = y
30 - y = 20 - y + y
30 - 20 = y + y - y
10 = y
c) Number of respondents that chose PUBG and Clash of clans =
n ( C ∩ PUBG) = z
20 - z = 15 - z + z
20 - 15 = z + z - z
5 = z
Step 2
How many Respondents chose all 3 online games
= n ( PUBG ∩ M)
n (PUBG ∪ M ∪ C) = n(PUB ) + n ( M ) + n (C) – n ( M ∩ PUBG) – n ( C ∩ PUBG) – n ( M ∩ C) + n (PUBG ∩ M ∩ C)
50 = 30 + 20 + 15 - 15 - 5 - 10 + n (PUBG ∩ M ∩ C)
50 = 65 - 30 + n (PUBG ∩ M ∩ C)
50 = 35 + n (PUBG ∩ M ∩ C)
50 - 35 = n (PUBG ∩ M ∩ C)
n (PUBG ∩ M ∩ C) = 15
Therefore, the number of Respondents chose all 3 online games = 15

The function g(x) is graphed. On a coordinate plane, a curved line enters the plane at point (negative 2.3, 5), crosses the x- and y-axis at (0, 0), and leaves the plane at point (2.3, 5). Which statements about the function are true? Choose three options. g of 1 = negative 1 g of 0 = 0 g of 4 = negative 2 g of 1 = 1 g of negative 1 = 1
Answer:
c=(0,-9)
Step-by-step explanation:
A function g is said to be even if [tex]g(x) = g(-x)[/tex].
The statements about the function that are true, are:
[tex]g(1) = 1[/tex]
[tex]g(-1) = 1[/tex]
[tex]g(0) = 0[/tex]
From the question, we have the following points:
[tex](x_1,y_1) = (-2.3,5)[/tex]
[tex](x_2,y_2) = (0,0)[/tex]
[tex](x_3,y_3) = (2.3,5)[/tex]
We can assume that the function is an even function because the function satisfies the condition of an even function at:
[tex]g(-2.3) = g(2.3) = 5[/tex]
[tex](x_2,y_2) = (0,0)[/tex] means that:
[tex]g(0) = 0[/tex]
From the list of options:
[tex]g(1)= -1[/tex]
[tex]g(0) = 0[/tex]
[tex]g(4) = -2[/tex]
[tex]g(1) = 1[/tex]
[tex]g(-1) = 1[/tex]
The true options are:
[tex]g(1) = 1[/tex]
[tex]g(-1) = 1[/tex]
[tex]g(0) = 0[/tex]
They are true because:
[tex]g(0) = 0[/tex] represents point [tex](x_2,y_2) = (0,0)[/tex]
[tex]g(1) = 1[/tex] and [tex]g(-1) = 1[/tex] satisfy the condition of an even function [tex]g(1) = g(-1) = 1[/tex]
See attachment for the graph of the function.

Points D and E are aligned with a ruler. Point D is at the mark for 4.5 cm, and the distance between points D and Eis 3.4 cm. At which two marks on the ruler could point E be located? 0 cm or 3.4 cm 0 -3.4 cm or 0 cm 1.1 cm or 7.9 cm 0 -7.9 cm or 1.1 cm
Answer:
1.1 cm or 7.9 cm
Step-by-step explanation:
Given:
Point D mark for 4.5 cm
Distance between points D and E =3.4 cm
Find:
Location of point E
Computation:
Assume;
Point o = 0 cm mark
Point E = Point D mark - Distance between points D and E
Point E = 4.5 cm - 3.4 cm
Point E = 1.1 cm
or
Point E = Point D mark + Distance between points D and E
Point E = 4.5 cm + 3.4 cm
Point E = 7.9 cm
What are the coordinates of the point 3/4 of the way from A to B. I need this ASAP pls
Answer:
The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)
Step-by-step explanation:
The coordinates of the point A is (-5, -4),
The coordinates of the point B is (-3, 3)
Let the point 3/4 from A to B = P
The coordinates of the point 3/4 from A to B is found as follows;
(-5 + (3/4×(-3 - (-5)), -4 + 3/4×(3 - (-4)) which gives;
The coordinates of the point 3/4 from A to B as P(-3.5, 1.25)
We verify the length from A to B and from A to P as follows;
The distance l between two points (x₁, y₁) and (x₂, y₂) is given by the formula;
[tex]\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
For AB, we have;
[tex]Length \ of \ segment \ \overline {AB} = \sqrt{\left (3-(-4) \right )^{2}+\left ((-3)-(-5) \right )^{2}}=\sqrt{53} \approx 7.28[/tex]
[tex]Length \ of \ segment \ \overline {AP} = \sqrt{\left (1.25-(-4) \right )^{2}+\left ((-3.5)-(-5) \right )^{2}}= \dfrac{3}{4} \cdot \sqrt{53}[/tex]
Therefore, the point P (-3.5, 1.25) is the point 3/4 distance of A to B from A.
Identifying the distance and applying the fraction, it is found that the coordinates are (-3.5, 1.25).
------------
Point A has horizontal coordinate -5 and vertical coordinate -4, thus, it's coordinates are A(x,y) = A(-5,-4).Point B has horizontal coordinate -3 and vertical coordinate 3, thus, it's coordinates are B(-3,3).------------
At the x-coordinate, the distance from B to A is of [tex]-3 - (-5) = -3 + 5 = 2[/tex] units.Starting at point A, 3/4 of the way will have a x-coordinate of:[tex]x = -5 + 2\frac{3}{4} = -5 + \frac{6}{4} = -\frac{20}{4} + \frac{6}{4} = -\frac{14}{4} = -\frac{7}{2} = -3.5[/tex]
At the y-coordinate, the distance from B to A is of [tex]3 - (-4) = 3 + 4 = 7[/tex] units.Starting at point A, 3/4 of the way will have a y-coordinate of:[tex]y = -4 + 7\frac{3}{4} = -4 + \frac{21}{4} = -\frac{16}{4} + \frac{21}{4} = \frac{5}{4} = 1.25[/tex]
The coordinates are (-3.5, 1.25).

For each student in a certain class, a teacher adjusted the student's test score using the formula y = 0.8x + 20, where x is the student's original test score and y is the student's adjusted test score. If the standard deviation of the original test scores of the students in the class was 20, what was the standard deviation of the adjusted test scores of the students in the class?
A. 12
B. 16
C. 28
D. 36
E. 40
Answer: B. 16
Step-by-step explanation: If you add a constant to each number at the data set, standard deviation doesn't change. However, multiplying each data in the data set by a constant, also multiplies the standard deviation by that constant.
That being said, the formulafor the adjusted test score is
y = 0.8x + 20
Adding 20 to each data doesn't change standard deviation but multiplying by 0.8 changes it.
So, the new standard deviation is
σ = 20*0.8 = 16
Standard Deviation for the adjusted test scores of the students is 16.

Answer:
G'(-3, -2), E'(1, 1), W'(-3, 0)
Step-by-step explanation:
A point has coordinates (x, y).
A translation of h units to the right means add h to x.
A translation of h units to the left means subtract h from x.
A translation of k units up means add k to y.
A translation of k units down means subtract k from y.
The translation you need to do is 1 unit right and 2 units down.
That means add add 1 to x of each point. Subtract 2 from y of each point.

Ahmed started 6 floors below ground level, then he went down 8 floors.
Save and Exit
Answer: Choice A
Ahmed started 6 floors above ground level, then he went down 8 floors
The +6 or simply 6, is positive, so he's on the 6th floor to start. Then adding on -8, which is the same as subtracting 8, moves him down 8 floors.
6 + (-8) = 6 - 8 = -2 indicates he's 2 floors below ground level, so he's in basement level 2 (perhaps some kind of parking garage).

Answer:
4√(xy³)
Step-by-step explanation:
8√(x²y⁶)
The above expression can be simplified as follow:
8√(x²y⁶)
Recall:
m√a = a^1/m
Therefore,
8√(x²y⁶) = (x²y⁶)^1/8
Recall:
(aⁿ)^1/m = a^(n/m)
Therefore,
(x²y⁶)^1/8 = x^(2/8)•y^(6/8)
= x^1/4•y^3/4
= (xy³)^1/4
Recall :
a^1/m = m√a
Therefore,
(xy³)^1/4 = 4√(xy³)
Therefore,
8√(x²y⁶) = 4√(xy³)
