Two six-sided dice (number cubes) are rolled. Find the probability P(sum of 8 or doubles).
1/3 third
11/36
7/18
5/18
Answer:
5/18
Step-by-step explanation:
The attached chart shows all 36 outcomes, equally likely.
There are 6 outcomes that are doubles (along a diagonal), 5 outcomes that have a sum of 8, but the (4, 4) outcome should only be counted once!
You're interested in 6 + 5 - 1 = 10 outcomes out of the 36 possible outcomes.
Probability of double or sum = 8: 10/36 = 5/18

Write the equation of a circle whose center is (-2, 0) and has the point (-5,-6) on its circumference.
Answer:
(x+2)^2 + y = √45 ^2
Step-by-step explanation:
this should be right
Answer:
[tex](x + 2)^{2} + y^{2} = 45[/tex]
Step-by-step explanation:
The radius (r) of the circle is the distance between (-2, 0) and (-5, -6)
r = [tex]\sqrt{(-2 + 5)^{2} + (0 + 6)^{2} } = \sqrt{3^{2} + 6^{2} } = \sqrt{9 + 36} = \sqrt{45}[/tex]
[tex]r^{2}[/tex] = 45
[tex](x + 2)^{2} + y^{2} = 45[/tex] is the equation of the circle

Mark for review (Will be highlighted on the review page)
Alaviation
Answer:
D.(3, 3)
Step-by-step explanation:
The equation of a straight line is given as:
y = mx + c;
where x, y are variables, m is the slope of the line, c is the y intercept.
From the graph, we can see that line 1 passes through (6,0) and (0,6).
The equation of line 1 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{6-0}{0-6} (x-6)\\\\y=-x + 6\ \ \ (1)[/tex]
Line 2 passes through (6, 5) and (0, 1)
The equation of line 2 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-5=\frac{1-5}{0-6} (x-6)\\\\y=\frac{2}{3}x + 1\ \ \ (2)[/tex]
To get the coordinates of the intersection of the two lines, we solve equation 1 and 2 simultaneously using a calculator. This gives:
x = 3, y = 3
Therefore the two lines meet at (3, 3)

Answer:
310.86
Step-by-step explanation:
so V=Bh
and B=pi *r^2
so that means 3.14*9 (since 3^2 is 9)
3.14*9=28.26
then 28.26*11= 310.86

A popular internet subscription service for movies, TV series, and documentaries conducts a survey in which it randomly samples 1,000 of its customers. The survey asks the customers which way they use their streaming service the most: (1) watching movies, (2) watching TV series, or (3) watching documentaries. They also ask the level of satisfaction with the service they most often use (on a scale of 0 to 10 with 0 very poor and 10 excellent). Is there statistical evidence for this internet subscription service that the mean satisfaction differs between customers who watch movies, TV series, or documentaries the most?

According to a study in a medical journal, 202 of a sample of 5,990 middle-aged men had developed diabetes. It also found that men who were very active (burning about 3,500 calories daily) were a fourth as likely to develop diabetes compared with men who were sedentary. Assume that one-fifth of all middle-aged men are very active, and the rest are classified as sedentary. What is the probability that a middle-aged man with diabetes is very active
Answer:
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has diabetes.
Event B: Is very active.
Probability of having diabetes:
To find this probability, we take in consideration that:
It also found that men who were very active (burning about 3,500 calories daily) were a fourth as likely to develop diabetes compared with men who were sedentary. Assume that one-fifth of all middle-aged men are very active, and the rest are classified as sedentary.
So the probability of developing diabetes is:
x of 4/5 = x of 0.8(not active)
x/4 = 0.25x of 1/5 = 0.2(very active). So
[tex]P(A) = 0.8x + 0.25*0.2x = 0.85x[/tex]
Probability of developing diabetes while being very active:
0.25x of 0.2. So
[tex]P(A \cap B) = 0.25x*0.2 = 0.05x[/tex]
What is the probability that a middle-aged man with diabetes is very active?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05x}{0.85x} = \frac{0.05}{0.85} = 0.0588[/tex]
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active

Solve the equation x^2 - 16x+ 54 = 0 by completing the square.
Fill in the values of a and b to complete the solutions.
Answer:
[tex]x = 8\±\sqrt{10[/tex]
[tex]a =8[/tex] [tex]b = 10[/tex]
Step-by-step explanation:
Given
[tex]x^2 - 16x + 54 = 0[/tex]
Required
Complete the square
[tex]x^2 - 16x + 54 = 0[/tex]
Subtract 54 from both sides
[tex]x^2 - 16x + 54 -54= 0-54[/tex]
[tex]x^2 - 16x = -54[/tex]
--------------------------------------------------
Take half of - 16
[tex](-16/2) = -8[/tex]
Square the result
[tex](-8)^2 = 64[/tex]
Add the squared result to both sides of the equation
--------------------------------------------------
So, we have:
[tex]x^2 - 16x +64= -54+64[/tex]
[tex]x^2 - 16x +64= 10[/tex]
Expand
[tex]x^2 - 8x - 8x + 64 = 10[/tex]
Factorize
[tex]x(x - 8) - 8(x - 8) = 10[/tex]
Factor out x - 8
[tex](x - 8)(x - 8) = 10[/tex]
[tex](x - 8)^2 = 10[/tex]
Take square roots
[tex]x - 8 = \±\sqrt{10[/tex]
Solve for x
[tex]x = 8\±\sqrt{10[/tex]
We have:
[tex]x = a - \sqrt{b}[/tex]
[tex]x = a + \sqrt{b}[/tex]
By comparing the above with: [tex]x = 8\±\sqrt{10[/tex]
