Workout the probability that spinner A lands on 2 and spinner b does not land on b
Spinner diagram isn't attached. A related spinner diagram has been attached below to provide an hypothetical solution to the problem
Answer:
4 / 15
Step-by-step explanation:
For the numbered spinner :
P(landing on 2) = required outcome / Total possible outcomes
Total possible outcomes = (1, 2, 3) = 3
Required outcome = (1) = 1
P(landing on 2) = 1 /3
Lettered spinner :
P(does not land on b)
Total possible outcomes = (A, B, C, D, E)
Required outcome = (a, c, d, e)
P(does not land on b) = 4 / 5
Hence,
P(lands on 2, does not land on b) in this scenario is :
1/3 * 4/5 = 4 / 15

Step-by-step explanation:
In 1980 more than 35% of cars purchased had a manual transmission (i.e. stick shift). By 2007 the proportion had decreased to 7.7%. A random sample of college students who owned cars revealed the following: out of 133 cars, 31 had stick shifts. Estimate the proportion of college students who drive sticks with 90% confidence. Use a graphing calculator and round the answers to at least three decimal places. <
Answer:
The 90% confidence interval for the proportion of college students who drive sticks is (0.173, 0.293).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A random sample of college students who owned cars revealed the following: out of 133 cars, 31 had stick shifts.
This means that [tex]n = 133, \pi = \frac{31}{133} = 0.233[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.233 - 1.645\sqrt{\frac{0.233*0.767}{133}} = 0.173[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.233 + 1.645\sqrt{\frac{0.233*0.767}{133}} = 0.293[/tex]
The 90% confidence interval for the proportion of college students who drive sticks is (0.173, 0.293).

Solve the inequality for x.
- 3x + 6 < 15
Ox>-3
Ox<-3
0x<-7
Ox>-7
Answer:
x > -3
Step-by-step explanation:
-3x + 6 < 15
-3x < 15 - 6
-3x < 9
-x < 3
x > -3
A. x > -3
Step-by-step explanation:
Step 1: Subtract 6 from both sides.
−3x + 6 − 6 < 15 − 6
−3x < 9
Step 2: Divide both sides by -3.
−3x/−3 < 9/−3
x > −3

-6(2p + 1) = -7p - 31
Answer:
P=5
Step-by-step explanation:
-6(2p + 1) = -7p - 31
Expand -6(2p+1)
Apply distributive law;
a=-6, b=2p, c=1
=-6*2p+(-6)*1
=-6*2p-6*1
Simplify; -6*2p-6*1
=-12p-6
-12p-6=-7p-31
Add 6 to both sides;
-12p-6+6=-7p-31+6
simplify;
-12p=-7p-25
Add 7p to both sides;
-12p+7p=-7p-25+7p
Simplify;
-5p=-25
Divide both sides by -5
-5p/-5=-25/-5
Simplify:
p=5
Answered by the One and Only #DrippQueenMo
Answer:
p=5
Step-by-step explanation:
first you want to get rid of the parentheses in -6(2p+1) so take -6 and times it by 2p and 1 to get -12p-6. You can do this because of the distributive property. Now you have the equation -12p - 6 = -7p - 31. So now you want to get the p values on one side. Adding 7p to both sides of the equations get rid of the -7p. -12p + 7p equals -5p so now you have the equation -5p - 6 = -31. so now you need to get the whole numbers on one side. So add 6 to both sides so you can get rid of the -6. this leaves you with the equation -5p= -25. Now to find the value of p you divide both sides by -5. This gives you p = 5.

Question:
Identify the sets that contain 2 as an element. (Check all that apply.)
[tex]A.\ \{2, 3, 4, 5, ...\}[/tex]
[tex]B.\ \{0, 1, 4, 9, ...\}[/tex]
[tex]C.\ \{2, \{2\} \}[/tex]
[tex]D.\ \{\{2\}, \{\{2\}\}\}[/tex]
[tex]E.\ \{\{2\}, \{2, \{2\}\}\}[/tex]
[tex]F.\ \{\{\{2\}\}\}[/tex]
Answer:
[tex]A.\ \{2, 3, 4, 5, ...\}[/tex]
[tex]C.\ \{2, \{2\} \}[/tex]
Step-by-step explanation:
Required
For which of the options is 2 an element
[tex]A.\ \{2, 3, 4, 5, ...\}[/tex]
The elements of this set starts from 2, then 3 and continues as thus.
Hence: 2 is an element
[tex]B.\ \{0, 1, 4, 9, ...\}[/tex]
From the given elements in the above set, 2 is not listed.
Hence: 2 is not an element of this set
[tex]C.\ \{2, \{2\} \}[/tex]
Here, 2 is listed as an element, 2 is also listed as a subset.
Since 2 is listed as an element, then 2 is an element of the set.
[tex]D.\ \{\{2\}, \{\{2\}\}\}[/tex]
Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.
Since 2 is not listed as an element itself, then 2 is not an element of the set.
[tex]E.\ \{\{2\}, \{2, \{2\}\}\}[/tex]
Here, 2 is listed as a subset of {2} and also as a subset of subset of {2,{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.
Hence: 2 is not an element of the set
[tex]F.\ \{\{\{2\}\}\}[/tex]
Here, 2 is listed as a subset of subset of {{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.
Hence: 2 is not an element of the set
Answer:

Step-by-step explanation:
find equation of the line that contains the point (4,-2) and is perpendicular to the line y= _2x+8
Answer:
y = 1/2x - 4
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = -2x + 8. Its slope is -2. A line perpendicular to this one will have a slope of 1/2.
Plug this value (1/2) into your standard point-slope equation of y = mx + b.
y = 1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -2). Plug in the x and y values into the x and y of the standard equation.
-2 = 1/2(4) + b
To find b, multiply the slope and the input of x (4)
-2 = 2 + b
Now, subtract 2 from both sides to isolate b.
-4 = b
Plug this into your standard equation.
y = 1/2x - 4
This equation is perpendicular to your given equation (y = -2x + 8) and contains point (4, -2)
Hope this helps!

Answer:
y = 1/2x -4
Step-by-step explanation:
We presume the given line is ...
y = -2x +8
This is in slope-intercept form, which allows us to determine easily that the slope of this line is -2.
A perpendicular line will have a slope that is the opposite reciprocal of -2:
m = -1/(-2) = 1/2
The y-intercept of the desired line can be found from the point (x, y) = (4, -2) using the equation ...
b = y - mx
b = -2 -(1/2)(4) = -4
Now, we know the slope and y-intercept of the desired perpendicular line through (4, -2), so we can write its equation as ...
y = 1/2x -4
__
Additional comment
"Slope-intercept form" is ...
y = mx + b . . . . . . where m is the slope and b is the y-intercept

Tinley is training to run a half-marathon. She sets a pace so that every mile takes
7 minutes.
Write an equation for the amount of time,
t, it takes Tinley to run
m miles.
Answer:
t=7m
Step-by-step explanation:
In this equation, "t" represents time, and "m" represents miles. Each mile is 7 minutes. To find how much time this run will take her, multiple the amount of miles she will run by 7.
For example:
If Tinley runs 13 miles you should do-
7(13)= 91
13 miles would take Tinley 91 minutes

A rock with a mass of 25 g is added to a graduated cylinder containing 45 mL of water. The water level rises to the 50mL mark. Based on this information, what is the density of the rock?
Answer:
We know the density of water is 1 gm/ml
Mass of rock = 25 g
Volume of rock = 5 ml
So the density of the rock is 25 g / 5 ml = 5 gm / ml

used 3 triangles to make a straight angle. The measures of the angles
are (9x - 72). (73x + ) and 11) What is the measure of the
obtuse angle? 7.3.5
ext
Tota
Answer:
x = 2.93
Step-by-step explanation:
The sum of angles of the triangle is 180degrees, hence;
9x - 72 + 73x + 11 = 180
82x - 61 = 180
82x = 180 + 61
82x = 241
Divide both sides by 82
82x/82 = 241/82
x = 2.93

The value of y varies directly as the cube of u and y = 54 when I = 3. Find the equation that represents this relationship.
Answer:
2x^3
Step-by-step explanation:
The equation that represents this relationship will be y = 2u³.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The value of y varies directly as the cube of u. y = 54 when u = 3.
y ∝ u³
Removed the proportionality constant and place the equal sign with constant k.
y = ku³
Put y = 54 when u = 3, then the value of k will be
54 = k (3)³
54 = 27k
k = 2
Then the equation that represents this relationship will be
y = 2u³
The equation that represents this relationship will be y = 2u³.
