Answer:
0.2047
0.2377
Step-by-step explanation:
1.
What we have here is a binomial distribution
Probability p = 0.12
N = number of students in the class = 30
Probability of finding 4 left handers
P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶
= 27405 x 0.00020736 x 0.03602047835
= 0.2047
2.
This is also a binomial distribution
N = 10 p = 0.65
P(of 6 knowledgeable fans)
= 10C6 x (0.65)⁶ x (0.35)⁴
= 210 x 0.0754189 x 0.01500625
= 0.2377

What is the equation of the line –3x–2y=30 in slope-intercept form?
Enter your answer in the box.
Answers
Answer:
y = - 1.5x - 15
Step-by-step explanation:
Step 1:
- 3x - 2y = 30 Equation
Step 2:
- 2y = 3x + 30 Add 3x on both sides
Step 3:
y = - 1.5x - 15 Divide 2 on both sides
Answer:
y = - 1.5x - 15
Hope This Helps :)
Answer: y = - 1.5x - 15
Step-by-step explanation:
First, we will add 3x to both sides of the equation.
-2y = 3x + 30
Next, we will divide 2 on both sides of the equation.
y = -1.5x - 15
Answer - y = -1.5x - 15

the ratio of the measures of the angles of a triangle is 1:2:3 find the measures of each angle
Answers
Given:
The ratio of the measures of the angles of a triangle is 1:2:3.
To find:
The measures of each angle.
Solution:
Let the measure of angles be x, 2x and 3x respectively.
We know that, sum of all the interior angles of a triangle is 180 degrees by the angle sum property.
Using angle sum property, we get
[tex]x+2x+3x=180^\circ[/tex]
[tex]6x=180^\circ[/tex]
Divide both sides by 6.
[tex]x=\dfrac{180^\circ}{6}[/tex]
[tex]x=30^\circ[/tex]
Now,
First angle: [tex]30^\circ[/tex]
Second angle: [tex]2(30^\circ)=60^\circ[/tex]
Third angle: [tex]3(30^\circ)=90^\circ[/tex]
Therefore, the measure of all the angles are 30°, 60° and 90° respectively.

Write an equation of the line that passes through (1, -8) and is parallel to the line y = -3x - 7
Answers
Answer:
the desired new equation is y = -3x - 5
Step-by-step explanation:
The desired equation of this new (parallel) line has exactly the same form as the given line y = -3x - 7. Only the y-intercept will be different.
Starting with y = -3x - 7, replace x with the x-coordinate of the given point (1, -8) and y with the y-coordinate. We get:
-8 = -3(1) + C, where C is the new y-intercept and is to be determined.
Then C = -5, and the desired new equation is y = -3x - 5.

Answer:

Step-by-step explanation:
When it's talking about going to the infinity, negative or positive, it just means when the line is going down with no end on the graph (in regards to y because that would be a vertical amount aka up and down). When it's in regards to x, it's the same concept except if it's negative infinity for x, it's on the left side. And if it's positive infinity for x, it's on the right side.

Last week, Charlie put 15 gallons of gas in his car and paid $50.25. Yesterday, Charlie put 12 gallons of gas in his car and paid $40.20. If the price of gas remains the same, how much will it cost Charlie to put gas in his car next week? Select ALL that apply.
A
Charlie can put 8 gallons of gas in his car for $26.80.
B
Charlie can put 11 gallons of gas in his car for $38.65.
C
Charlie can put 14 gallons of gas in his car for $47.90.
D
Charlie can put 17 gallons of gas in his car for $56.95.
Answers
Answer:
A and D
Step-by-step explanation:
So I divided $50.25 by 15 and I got 3.35. Then I divided $40.20 by 12 and got 3.35 again. So I multiplied 8, 11, 14, and 17 by 3.35. I got the right answer for 8 (A) and 17 (D).

Solve for h.

Answers
Answer:
[tex]\frac{1}{1.6} = \frac{h}{7.2}[/tex] ( since they're similar, they are proportional to each other)
1 (7.2) = h (1.6) (set the two up as a proportion and then cross multiply)
7.2 = 1.6h (divide both sides by 1.6)
h = 4.5 m (this is the answer)

Answer: 29
Step-by-step explanation: 180-146= 34-5 29.
Answer:
[A] 29
Explanation:
Equation: 180 = 146 + (x + 5)
The line adds up to 180, so we need to find what x is180 = 146 + (x + 5)
Switch Sides
146 + (x + 5) = 180
Remove Parenthesis
146 + x + 5 = 180
Group Like Terms
x + 146 + 5 = 180
Add: 146 + 5 = 151
x + 151 = 180
Subtract 151 From Each Side Of Equation
x + 151 - 151 = 180 - 151
x = 29
