10(x+4)-3=14x+1
10(4x)-3=14x+1
40x-3=14x+1
37x=14x+1
37x=15x
X=2.5
Or your answer will be 37x=15x
Answer:
B
Step-by-step explanation:
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
consecutive positive integers...x, x + 1, x + 2
x (x + 2) - (x + 1) = 33(x + 2) + 1
x^2 + 2x - x - 1 = 33x + 66 + 1
x^2 + x - 1 = 33x + 67
x^2 -32x - 68 = 0
(x + 2)(x - 34) = 0
x + 2 = 0
x = -2 ...not this one because it is negative
x - 34 = 0
x = 34
x + 1 = 34 + 1 = 35
x + 2 = 34 + 2 = 36
ur numbers are 34,35,36
Answer:
6
Step-by-step explanation:
Given that :
The school children are going for a school field trip. There are total forty - six number of students for the field trip.
They are asked to form groups of seven students in a group.
Therefore they will form = 
= 6.5
Therefore there will 6 number of groups having 7 students. And the remaining 4 students will form another group.
So there will be 6 groups of seven in each group.
