Hope this helps! :)
Answer:
B. 4y - 2
Step-by-step explanation:
2( y + 1 ) + 2( y - 2 )
= 2y + 2 + 2y - 4
= 2y + 2y + 2 - 4
= 4y - 2
= 4y - 2
4,284 passengers traveling by the intercity bus every day, the intercity bus operates 6 hours every day, find the number of passengers every hour
Please do it as quick as possible
Answer:
714
Step-by-step explanation:
So lets go over what we know.
The bus only goes for 6 hours each day.
So lets just think of a full day as 6 hours.
Each day(6 hours), 4284 passangers ride the bus.
To find passangers per hour, we must divide the total passangers by the total hours.
This is 4284(total passangers) divided by 6(total hours):
4284/6
=
714
So each hour, there are 714 passangers.

If <3 measures 123, what is the measure of <7?
Madison
River
A bridge crosses over the Madison River.
The opposite banks of the river are parallel
and the bridge is a transversal.
A. 90°
B. 123
C. 180°
D. 57
Answer: B
Step-by-step explanation: I just took the quiz
The measurement of angle 7 is 123°.
What are corresponding angles?The corresponding angles are angles that have the same relative position or measurement in two similar figures. They are formed when two lines, parallel or not, are intersected by a transversal. They are located on the same side of the transversal. Corresponding angles formed by parallel lines and a transversal are congruent.
Given is scene of two parallel line intersected by a transversal,
∠3 = 123°, We need to find the value of ∠7,
We see that, the angles, ∠3 and ∠7 are corresponding angles,
Therefore,
∠3 = ∠7 by the definition of corresponding angles between parallel lines,
Therefore, ∠7 = 123°.
Hence, the measurement of angle 7 is 123°.

A А.
D
UJ
с
Answer:
AEB =43
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
AED + AEB = 180
137+AEB = 180
AEB = 180-137
AEB =43
Answer:
[tex]\text{B. }43^{\circ}[/tex]
Step-by-step explanation:
Angles [tex]\angle AED[/tex] and [tex]\angle AEB[/tex] are supplementary, meaning they add up to 180 degrees, because they form one side of a line.
Thus, we have:
[tex]\angle AED+\angle AEB=180,\\137+\angle AEB=180,\\\angle AEB=\boxed{43^{\circ}}[/tex]

Write the error interval for x , where x=4.7 , truncated to 1 decimal place.
Error interval for x is 4.65 ≤ x < 4.75.
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
The error is rounding the number is half of the unit of measure.
The number was rounded to the nearest 0.1 unit. so the error is half of 0.1 which is [tex]\frac{1}{2}[/tex] × [tex]0.1[/tex] = 0.05
∵ 4.7 + 0.05 = 4.75
and 4.7 - 0.05 = 4.65
Error interval for x is 4.65 ≤ x < 4.75.

0.2805
0.6141
0.47385
0.3336
None of the above.
Answer:
0.2805
Step-by-step explanation:
Given that p = 20% = 0.2, n = 300.
The mean (μ) = np = 0.2 * 300 = 60
The standard deviation (σ) = [tex]\sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93[/tex]
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma }[/tex]
For x = 57:
[tex]z=\frac{57-60}{6.93 } =-0.43[/tex]
For x = 62:
[tex]z=\frac{62-60}{6.93 } =0.29[/tex]
From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805

Step-by-step explanation:
Hi there!
1) Find the length of the other leg in the right triangle
There are two ways we can go about this. The first way is to use trigonomic ratios:
We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:
[tex]tan\theta=\frac{opp}{adj}[/tex]
Let x be equal to the length of the other leg. Plug in the known values:
[tex]tan45=\frac{x}{7}\\7*tan45=x\\x=7[/tex]
The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.
2) Determine the height of the hoop
Add 7 ft and 5 ft (the person's height):
7+5=12 ft

A research center project involved a survey of 846 internet users. It provided a variety of statistics on internet users. (a) The sample survey showed that 94% of respondents said the internet has been a good thing for them personally. Develop a 95% confidence interval for the proportion of respondents who say the internet has been a good thing for them personally. (Round your answers to four decimal places.) 0.9239 Incorrect: Your answer is incorrect. to 0.9561 Incorrect: Your answer is incorrect. (b) The sample survey showed that 67% of internet users said the internet has generally strengthened their relationship with family and friends. Develop a 95% confidence interval for the proportion of respondents who say the internet has strengthened their relationship with family and friends. (Round your answers to four decimal places.) 0.6385 Incorrect: Your answer is incorrect. to 0.7015 Incorrect: Your answer is incorrect.
Answer:
(a) (0.9240, 0.956)
(b) (0.6383, 0.7017)
Step-by-step explanation:
The number of internet users involved in the survey, n = 846
The percentage of the respondents that said the internet has been good thing for them personally, [tex]\hat p[/tex] = 94%
(a) The confidence interval of a percentage is given as follows;
[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]
The z-value for 95% confidence interval = 1.96
We get;
[tex]CI=0.94\pm 1.96\times \sqrt{\dfrac{0.94 \times (1-0.94)}{846}} \approx 0.94 \pm 1.6003 \times 10^{-2}[/tex]
CI = 0.9240 ≤ [tex]\hat p[/tex] ≤ 0.956 = (0.9240, 0.956)
(b) The percentage of the internet users that said the internet has directly strengthened their relationship with their families, [tex]\hat p[/tex] = 67% = 0.67
The 95% confidence interval is therefore;
[tex]CI=0.67\pm 1.96\times \sqrt{\dfrac{0.67 \times (1-0.67)}{846}} \approx 0.67 \pm 3.1686\times 10^{-2}[/tex]
From which we have;
CI = 0.6383 ≤ [tex]\hat p[/tex] ≤ 0.7017 = (0.6383, 0.7017)

Find the slope for the two functions
Function A:
(1 , 5) & (2 , 7)
Slope = Change in y ÷ change in x
[tex]= \frac{7-5}{2-1}\\\\= \frac{2}{1}\\\\= 2[/tex]

Helppppppppppppppppppp I’ll mark you brainlist don’t respond if you’re going to put something random I will report you :)
Answer:
slope = 1
Step-by-step explanation:
A standard linear function is
y = mx + b
where m = slope, b = initial value
Given y = x + 6
slope m = 1, b = 6
Slope of a line parallel to the given line should have the same slope, therefore slope required is m = 1.

Suppose a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60degrees. What is the length of the third side of the triangle?
Answer:
A) 2
Step-by-step explanation:
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(A)/a=sin(B)/b=sin(C)/c
Substitute the known values into the law of sines to find a.
sin(60)/a=sin(60)/2
