Answer: Then the sample space is 36.
Step-by-step explanation:
n is the number of possible combinations.
Now, as the die are of different colors, the case where:
white = 1 blue = 2, sum = 1+ 2 = 3
white = 2 blue = 1, sum = 2 + 1 = 3
are different.
So the number of possible combinations is:
6 options for the white dice and 6 options for the blue dice, so we have:
6*6 = 36 different combinations.
Then the sample space is 36.

Answers
Answer:
x = -2 ±sqrt( 10)
Step-by-step explanation:
x^2 + 4x = 6
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add this to each side
x^2 + 4x+4 = 6+4
Take the 4/2 term which is the factor inside the (x+ )^2
(x+2)^2 = 10
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 10)
x+2 = ±sqrt( 10)
Subtract 2 from each side
x+2-2 = -2±sqrt( 10)
x = -2 ±sqrt( 10)
Answer:
x= +/- \sqrt(10) - 2
Step-by-step explanation:
use the formula (b/2) in order to create a new term.

Answer:
The measure of angle 2 is 38 degrees
Step-by-step explanation:
38 degrees and angle 6 are vertical angles and are equivalent. Angle 6 and 2 are alternate interior angles meaning that they are also equivalent. So the angle of measure 2 must be 38 degrees.
Answer: 38 degrees
Step-by-step explanation: angle 8 is an exterior angle to angle 4. Angle 4 is vertical to angle 2 so the answer would be 38 degrees.

Step-by-step explanation:
The given question is incomplete. Let as consider we need to find [tex](g\circ h)(5)[/tex]
The given functions are
[tex]h(x)=x-7[/tex]
[tex]g(x)=x^2[/tex]

Find the volume of a pyramid with a square base, where the area of the base is
12.7 ft- and the height of the pyramid is 17.8 ft. Round your answer to the nearest
tenth of a cubic foot.
Answers
Answer:
Volume, [tex]V= 75.35\ \text{feet}^3[/tex]
Step-by-step explanation:
We have,
Area of the base of of a pyramid with a square base is 12.7 ft
Height of the pyramid is 17.8 ft
It is required to find the volume of of a pyramid with a square base.
The formula used to find the volume of a pyramid with a square base is given by :
[tex]V=\dfrac{1}{3}Ah[/tex]
Plugging all the values in above formula
[tex]V=\dfrac{1}{3}\times 12.7\times 17.8\\\\V=75.35\ \text{feet}^3[/tex]
So, the volume of a pyramid is [tex]75.35\ \text{feet}^3[/tex].
Answer: 75.4 ft^3 when rounded
Step-by-step explanation:
Volume of Pyramid V=1/3BH
Area of base= 12.7
h=17.8
V=1/3 (12.7)(17.8)
V=75.353333
V=75.4 ft^3
A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Everyone liked at least one sport except 7 kids, which doesn't like any of these three kind of sports. 12 children liked Chess and Football but not Swimming, 16 children liked Chess and Swimming but not Football, 8 children liked Swimming and Football but not Chess, 10 children liked Chess only, 40 children liked Swimming, 32 student liked Football.
a)Find the number of kids who liked Swimming and Football.
b)What is the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?
c)What is the probability that a randomly-chosen child from this group does not like active kinds of sport?
Answers
Answer:
see below
Step-by-step explanation:
Let C = chess
S = swimming
F = football
x = football only
y = all three sports
z = swimming only
x+y+ 8+12 = 32 those who like football
y+z+8+16 = 40 those who like swimming
7+x+8+y+12+10+16+z = 72 all children
Simplifying these equations
x+y = 32-20 = 12
y+z = 40-24 = 16
x+y +z = 72-53 = 19
Substituting x+y = 12 into the last equation
12 +z = 19
z = 7
y+z = 16
y = 9
x+y =12
x =5
Swimming only is 7
Football only is 5
Swimming and football y+8 = 9+8 = 17
P( chess or swimming but not football) = (10+16+z)/ total
=(10+16+7)/ total
=33/72
P( no active sport) = chess only or no sport/total
=(10+7)/72
The ratio of red marbles to blue marbles in a bag is 2 to 5. If there are 60
more blue marbles than red marbles in the bag, how many marbles are
there all together?
Answers
Answer:
140
Step-by-step explanation:
Let's call the red and blue marbles 2x and 5x. We know that 5x = 2x + 60, so x = 20. The sum of all marbles in the bag is 2x + 5x = 7x which is 7 * 20 = 140 marbles. Hope this helps!
Answer:
84 in all.
Step-by-step explanation:
if there are 2 red marbles to every 5 marble than 60 / 5 = 12, 12 x 2 = 24 + 60 = 84.
At a charity raffle event they are giving out tickets labeled 1 through 10 when people come through the doors. If you are given an even-numbered ticket, you are given a prize at the end of the evening. The table shows the results of 500 guests. What is the relative frequency for the guests who will receive a prize? Ticket Number 1 2 3 4 5 6 7 8 9 10 Frequency 48 42 41 56 67 43 39 41 55 68
Answers
Answer:
Relative frequency for guest who will win the prize:
Relative frequency = 50%
Step-by-step explanation:
Total No. of guest = 500
No. of Guests with even-numbered tickets:
Ticket NO. 2 = 42
Ticket NO. 4 = 56
Ticket NO. 6 = 43
Ticket NO. 8 = 41
Ticket NO. 10 = 68
Total No. of Guest with even-numbered ticket = 42+56+43+41+68
Total No. of Guest with even-numbered ticket = 250
So.
Relative frequency = (frequency of desirable event/ total frequency) · 100
Relative frequency = (250/500)· 100
Relative frequency = 50%

Solve h = - 16t2 + 36 for the time t in seconds it takes for the height h to reach 0. Apply the square root method.
Answers
Step-by-step explanation:
I'm not sure what the square root method is, but I'm assuming that you factor.
This is how I would solve it:
[tex]h = - 16 {t}^{2} + 36 \\ 0 = - 16 {t}^{2} + 36 \\ 0 = - 4(4 {t}^{2} - 9) \\ 0 = (2t - 3)(2t + 3) \\ t = \frac{3}{2} \\ t = - \frac{3}{2} [/tex]
Since time can't be negative, you rule out the -3/2.

The one-year survival rate for pancreatic cancer is 20%. Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year. What is the probability of that happening.
Answers
Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;
[tex]P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,......[/tex]
where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = Number of people survived one year
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) = [tex]\binom{12}{6} \times 0.20^{6} \times (1-0.20)^{12-6}[/tex]
= [tex]924 \times 0.20^{6} \times 0.80^{6}[/tex]
= 0.0155

Which parabola will have one real solution with the line y = x – 5? y = x2 + x – 4 y = x2 + 2x – 1 y = x2 + 6x + 9 y = x2 + 7x + 4
Answers
Answer:
y = x² + 7x + 4
Step-by-step explanation:
First option
System of equations:
y = x² + x – 4
y = x – 5
Replacing:
x - 5 = x² + x – 4
0 = x² + x – 4 - x + 5
0 = x² + 1
Discriminant:
b²-4*a*c
0²-4*1*1
-4 < 0 then the equation has no real roots
Second option
System of equations:
y = x² + 2x – 1
y = x – 5
Replacing:
x - 5 = x² + 2x – 1
0 = x² + 2x - 1 - x + 5
0 = x² + x + 4
Discriminant:
b²-4*a*c
1²-4*1*4
-15 < 0 then the equation has no real roots
Third option
System of equations:
y = x² + 6x + 9
y = x – 5
Replacing:
x - 5 = x² + 6x + 9
0 = x² + 6x + 9 - x + 5
0 = x² + 5x + 4
Discriminant:
b²-4*a*c
5²-4*1*4
9 > 0 then the equation has two different real roots
Fourth option
System of equations:
y = x² + 7x + 4
y = x – 5
Replacing:
x - 5 = x² + 7x + 4
0 = x² + 7x + 4 - x + 5
0 = x² + 6x + 9
Discriminant:
b²-4*a*c
6²-4*1*9
0 then the equation has one real root

Answers
Answer:

Step-by-step explanation:
The midsegment of a triangle theorem states that:
The midsegment is 1/2 of it's parallel side.
So,
6x + 5 = 1/2(4x + 26)
6x + 5 = 2x + 13
6x - 2x + 5 = 13
4x + 5 = 13
4x = 13 - 5
4x = 8
x = 8 ÷ 4
x = 2
Substitute x to the midsegment.
6x + 5
6(2) + 5
12 + 5
