which is the missing number in the sequence below?
5,6,9,15,?,40
Answer:
25
Step-by-step explanation:
The pattern is + 1, + 3, + 6,... i.e. + 1, + (1 + 2), + (1 + 2 + 3),...
.'. Missing number = 15 + (1 + 2 + 3 + 4) = 25.
Answer: 25!
Step-by-step explanation:
5, 6, 9, 15, ?, 40
5 + 1 = 6
6 + 1 + 2 = 6 + 3 = 9
9 + 1 + 2 + 3 = 9 + 6 = 15
15 + 1 + 2 + 3 + 4 = 15 + 10 = 25
25 + 1 + 2 + 3 + 4 + 5 = 25 + 15 = 40

2. Priscilla is drawing a map of her school that uses a scale in which 1.5 cm 1 point
on the map represents 3 ft. If the first hallway has a length of 120 ft, what
should the length of the hallway be on the map?
O
a. 40 cm
b. 60 cm
C. 30 cm
d. 45 cm
Answer:
The answer is 60cm. (b)
Step-by-step explanation:
For every 1.5cm on the map, it represents 3 ft on real-size scale.
In other words, for every 1cm on the map, it represents 3/1.5 = 2ft on real size scale.
If you want to find 120ft of real-size scale, you can use 120ft/2ft * 1cm which gives 60cm

What is the equation of the line that has a slope of -2 and passes through the point (-1, 2)?
Answer:
[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]
Answer:
y = -2x
Step-by-step explanation:
The equation of a line in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point
2 = -2(-1)+b
2 = 2+b
Add -2 to each side
2-2 =b
0=b
y = -2x+0
y = -2x
-2(5x+8)=14+6x step by step
Answer:
x=-15/8
Step-by-step explanation:
Hi there!
We're given the equation -2(5x+8)=14+6x and we need to find the value of x
we do this by isolating the variable so that x is on one side, and everything else is on the other
First, we need to do the distributive property on the left, as the -2 is factored out of 5x+8 and it makes solving for x harder
-2(5x+8)=14+6x
multiply both 5x and 8 by -2
-10x-16=14+6x
add 16 to both sides to clear it from the left side (-16+16=0)
-10x-16=14+6x
+16 +16
_____________
-10x=30+6x
subtract 6x from both sides (6x-6x=0)
-10x=30+6x
-6x -6x
_____________
-16x=30
now, we do have x by itself, but we have -16 attached to it; we need the value of 1x, or x without any coefficient in the front of it
divide both sides by -16
x=30/-16
simplify (divide both sides by -2)
x=-15/8
we can leave it as an improper fraction
Hope this helps! :)
Answer:
x = 15 / 8
Step-by-step explanation:
−2(5x+8) = 14 + 6x
Simplify both sides of the equation.
−2(5x+8) = 14 +6x
(−2)(5x) + (−2)(8) = 14 +6x (Distribute)
−10x +−16 = 14 +6x
−10x −16 = 6x +14
Subtract 6x from both sides.
−10x −16 −6x = 6x + 14 −6x
−16x −16 = 14
Add 16 to both sides.
−16x −16 +16 = 14 + 16
−16x=30
Divide both sides by -16.
-16 x / - 16 = 30/-16
Simplify ( divide RHS side by - 2 )
x = 15 / 8

Suppose a normal distribution has a mean of 48 abd a standard deviation of 5. What is the probability that a data value is between 48 and 52?
Answer:
P(48<x<52) = 0.2881
Step-by-step explanation:
P(48<x<52) = normalcdf(lower,upper,µ,σ) = normalcdf(48,52,48,5) ≈ 0.2881
Therefore, the probability that a data value is between 48 and 52 is 0.2881, or about a 28.81% chance of occurrence.

The equation of line is shown in the graph.
What is slope or gradient of a line?The slope or gradient of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope or gradient = Rise/Run
From the given graph, the gradient of a line is
Slope = rise/run
= -4/1.2

l give brainiest
Answer:
N= -3
Step-by-step explanation:
4n+2 = 6(1/3n - 2/3)
4n+2 = 2n - 4
2n +2 = -4
2n = -6
n = -3
Answer:
- 3
Step-by-step explanation:
4n + 2 = 6 ( 1 / 3 n - 2 / 3 )
Divide 2 on both sides,
2n + 1 = 3 ( 1 / 3 n - 2 / 3 )
2n + 1 = 3n / 3 - 6 /3
2n + 1 = n - 2
2n - n = - 2 - 1
