The sum of two odd consecutive integers is 88. Find the integers.
-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)
use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.
(2n + 1) + (2n + 3) = 88
add like terms.
4n + 4 = 88
4n = 84
n = 21
now plugin.
2(21) + 1
42 + 1
= 43 (the first odd integer)
this means the second one would be 45.
answer: 43 and 45
add them to check:
43 + 45 = 88

Erik added 23 new contacts to phone list He had to delete 18 old contacts before could add any more. He now has a total of 100 contacts. Let c represent how many contacts had on phone list before updated it. Write an equation and then solve for c.
Answer:
c-18+23=100
c=95
Step-by-step explanation:
to prove that the answer is 95 subtract the 18 that she deleted to get 77 then add the 23 that she added after deleting 18 and you get 100
Answer:
c+23−16=100
c=93

Recall that for use of a normal distribution as an approximation to the binomial distribution, the conditions np greater than or equal to 5 and nq greater than or equal to 5 must be met. For p= 0.9, compute the minimum sample size needed for use of the normal approximation. Round your answer to the next whole number.
The minimum sample size needed for use of the normal approximation is =
Answer:
The minimum sample size needed for use of the normal approximation is 50.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 5
n(1-p) >= 5
In this question, we have that:
p = 0.9
Since p > 0.5, it means that np > n(1-p). So we have that:
[tex]n(1-p) \geq 5[/tex]
[tex]n(1 - 0.9) \geq 5[/tex]
[tex]0.1n \geq 5[/tex]
[tex]n \geq \frac{5}{0.1}[/tex]
[tex]n \geq 50[/tex]
The minimum sample size needed for use of the normal approximation is 50.

The table shows the average bill totals for given numbers of diners at Simone's restaurant. If the rate is constant and you graph this relationship with the number of people along the x-axis and bill amounts along the y-axis, which points will lie on the line you get?
a. (12, 470)
b. (20, 800)
c. (24, 1,020)
d. (27, 1,080)
e. (28, 1,110)
Answer: B and D
Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080
The point (20 , 800) and ( 27 , 1080 )lies on the line.
Option (b) and (d) is correct.
It is given that average bill totals for given numbers of diners at Simone's restaurant.
To find which points will lie on the line you get.
What is co-ordinate?Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
The rate is constant.
Graph this relationship with the number of people along the x-axis and bill amounts along the y axis.
y = mx + c
=> 40 =m+ c
80 = 2m + c
=> m = 40
40 = 40 + c
=> c = 0
Hence
y = 40x
x = 12 => y = 480
x = 20 => y = 800
x =24 => y = 960
x = 27 => y = 1080
x = 28 => y = 1120
Hence (20 , 800) and ( 27 , 1080 ) point lies on the line

Which linear inequality is represented by the graph?
O y s 2x + 4
Oys2x+3
O y z 2 / 3x + 3
O y 22x + 3
Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the boundary line passes through two point (0,3) and (2,4). So, the equation of boundary line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{4-3}{2-0}(x-0)[/tex]
[tex]y-3=\dfrac{1}{2}(x)[/tex]
[tex]y=\dfrac{1}{2}x+3[/tex]
The shaded area lies below the boundary line and the boundary line is a solid line. So, the sign of inequality must be ≤.
The required inequality is
[tex]y\leq \dfrac{1}{2}x+3[/tex]
Therefore, the correct option is B.
What is m ZSRW?
- 18
- 54
- 126
- 108
Answer:
126
Step-by-step explanation:
Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.
Finding angles in function of X:
Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So
[tex]3x = 2x + 18[/tex]
[tex]x = 18[/tex]
So
[tex]3x = 3(18) = 54[/tex]
Angle SRW:
Supplementary with 54. So
54 + SRW = 180
SRW = 180 - 54 = 126
So 126 is the answer.
3x-5y=15 in slope intercept form
Answer:
I think the answer will be y=3/5x-3
Answer:
y = 3/5x - 3
Step-by-step explanation:
Slope-intercept form is y = mx + b.
For this question, all you need to do is move some stuff around!
In slope intercept form, the x is on the right side, so you would first subtract x from both sides.
3x - 5y = 15
Next, you would divide both sides of the equation by -5 to get y by itself.
-5y = 15 - 3x
Finally, rearrange the equation. y = mx + b
y = -3 + 3/5x
y = 3/5x - 3
A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign-in square inches?
Answer: The answer is 530.66
Step-by-step explanation:
I took the test and 81.64 is wrong, It's 530.66
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
What is the area of a circle?The area of the circle is pi times the square of the radius of a given circle.
The area of the circle = [tex]\pi r^2[/tex]
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\pi r^2[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

–59
–6
Answer:
–59
Step-by-step explanation:
f(x) = -2x - 7
f(x) = -2(-4x + 6) - 7
f(x) = 8x - 12- 7
f(x) = 8x - 19
f(x) = 8(-5) - 19

Michael and Bill are 238 miles apart, traveling towards each other. If Bill travels 20 mph and Michael travels 14 mph how long until they meet?
Answer:
They will meet in 7 hours.
Step-by-step explanation:
They are traveling toward each other, which means that their relative speed is the sum of their speeds.
Bill travels 20 mph and Michael travels 14 mph
This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.
Michael and Bill are 238 miles apart, how long until they meet?
Each hour, they will be 34 miles closer. How many hours for 238 miles?
1h - 34 miles
x h - 238 miles
By rule of three
[tex]34x = 238[/tex]
[tex]x = \frac{238}{34} = 7[/tex]
They will meet in 7 hours.
