A researcher takes a random sample of 2,496 drivers and finds that 1,603 put their phone in "drive mode” to not be distracted while driving. A 90% confidence interval for the proportion of drivers who use "drive mode” on their phones is (0.626, 0.658). Which statement correctly interprets the interval? The researcher can be 90% confident that 64% of all drivers will use “drive mode” while driving. There is a 90% probability that the proportion of drivers who use “drive mode” lies between 0.626 and 0.658. The researcher can be 90% confident that the interval from 0.626 to 0.658 captures the true proportion of all drivers who use “drive mode.” If this procedure is repeated many, many times, the true proportion of drivers who use “drive mode” will be captured 90% of the time.
Answer:
The researcher can be 90% confident that the interval from 0.626 to 0.658 captures the true proportion of all drivers who use “drive mode.”

Solve for x if -10x + 67 = 17
A) x=4
B) x= -50
C) x=5
D) x=10
Answer:
x=5
Step-by-step explanation:
First off, you need to subtract 67 from 17 to get the variable alone.
That will leave you with -10x=-50
Then you need to divide -10 and -50,
Two negatives make a positive so
x=5
Answer is C

Answer:
B
Step-by-step explanation:
The only diagram representing a function is B.
All the others fail rhe vertical line test. Each of the x values should have one y value assigned.
Intercepts: independent practice Write the ordered pair describing the coordinates of each intercept. 1. X-intercept: -6 2. Y-intercept: -2.3 3. Y-intercept: 3/4
Answer:
[tex](-6, 0)[/tex]
[tex](0, -2.3)[/tex]
[tex](0,\frac{3}{4})[/tex]
Step-by-step explanation:
Solving (1). x-intercept: -6
At x intercept, [tex]y= 0[/tex]
So, the ordered pair is: [tex](-6, 0)[/tex]
Solving (2): y-intercept: -2.3
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0, -2.3)[/tex]
Solving (3): y-intercept: 3/4
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0,\frac{3}{4})[/tex]
Please answer question b math help ( please show work )
Answer:
a = 10.9
b = 10.4
Step-by-step explanation:
part a: use sine
⇒ sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 23 = [tex]\frac{y}{28}[/tex]
(sine 23 = 0.39)
⇒ 0.39 = [tex]\frac{y}{28}[/tex]
multiply each side by 28
⇒ 0.39 x 28 = [tex]\frac{y}{28}[/tex] x 28
⇒ 10.9
part b: use cosine
⇒ cos = [tex]\frac{adjacent}{hypotenuse}[/tex]
⇒ cos 29 = [tex]\frac{y}{12}[/tex]
(cos 29 = 0.87)
⇒ 0.87 = [tex]\frac{y}{12}[/tex]
multiply 12 on both sides
⇒ 0.87 x 12 = [tex]\frac{y}{12}[/tex] x 12
⇒ 10.4

Anyone know how to solve this? Im losing brain cells
Answer and Step-by-step explanation:
The answer is A.
y = x + 2 and y = -2x + 4
This is because:
- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).
- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

write an equation of the line that passes through the point (0,3) and whose slope is 2
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.
(CORRECT ANSWER GETS BRAINLIEST) What is the correct equation to find the missing value?
x + 2 + 153 = 90
x + 155 = 180
x + 155 = 90
x + 2 = 153
Answer:
x + 155 = 180
Step-by-step explanation:
Those angles are supplementary meaning that the sum of them equal 180
2+153=153
so x+155=180 is your answer

Answer:
1. x = 2
y = 1
2. x = 3 or 6 (Mistake or typo in problem)
3. y = 13
4. x = 7
y = 15
5. x = 4
Step-by-step explanation:
1. 6x - 3 = x + 7, 5x = 10, x = 2
3y + 2 = y + 4, 2y = 2, y = 1
2. There is most likely a typo. Either 8x = 24 and x = 3 or 2x + 10 = 3x + 4 and x = 6
3. 5y -3 = 2y + 36, 3y = 39, y = 13
4. 8y + 11 + 3y + 4 = 180, 11y + 15 = 180, 11y = 165, y = 15
7x = 3y + 4 = 49, x = 7
5. 7x - 10 = 4x + 2, 3x = 12, x = 4
Answer:
1.[opposite side of parallelogram are equal:]
6x-3=x+7
6x-x=7+3
x=10/5=2
x=2
again
y+4=3y+2
4-2=3y-y
y=2/2=1
y=1
2.
[diagonal of parallelogram bisect each other]
8x=24
x=24/8=3
x=3
again
2x+10=3x+4
10-4=3x-2x
x=6
3.
5y-3=2y+36 [alternate angle]
5y-2y=36+3
y=39/3=13
y=13°
4.
8y+11+3y+4=180°[co interior angle]
11y=180-15
y=165/11=15
y=15°
again
7x=3y+4=3×15+4=49° .[opposite angle of parallelogram are equal:]
5..[opposite side of parallelogram are equal:]
7x-10=4x+2
7x-4x=10+2
3x=12
x=12/3

Will's Pizza can make 12 pizzas in 45 minutes. How many pizzas can they make in 4 hours?
Answer:
64 pizzas
Step-by-step explanation:
4 hours is 240 minutes
12 x (240 / 45) = 64
Answer: 64
Step-by-step explanation:
Alright. We are trying to find out how many pizza's they can make in every 15 mins so we can find out each hour. 45 divided by 3 is 15, and 12 divided by 3 is 4, so they can make 4 pizzas in 15 mins and multiply that by 4 is 16 pizzas in 1 hour. We are looking for 4 hours though so we just multiply 16 by 4 and we get 64.

work out the circumference of a cirlce with a diameter of 1.8m
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )
Find the value of x in each triangle
