Answer: 0.0129
Step-by-step explanation:
Given : Sample size : n=32
The average amount of time spent texting over a one-month period is :
Standard deviation :
We assume that the time spent texting over a one-month period is normally distributed.
z-score :
For x= 199
Now by using standard normal table, the probability that the average amount of time spent using text messages is more than 199 minutes will be :-
Hence, the required probability = 0.0129

Answer:
y = 4x-13
Step-by-step explanation:
The standard equation of the line is y = mx+c
m is the slope
c is the intercept
Given the equation y = 4x+2
The slope m = 4
Substitute m = 4 and the given point into the formula y = mx+c
1 = 4(4)+c
1 = 14+c
c = -13
Get the equation
Recall that y = mx+c
y = 4x + (-13)
y = 4x-13
Hence the required equation is y = 4x-13

Step-by-step explanation:
Answer:
9120
Step-by-step explanation:
I'm assuming you mean LCM (Least Common Multiple).
Factor each number into powers of primes.
76 = 2²×19
96 = 2⁵×3
120 = 2³×3×5
Take the highest power of each prime used: 2⁵, 3, 5, 1
The LCM is their product: 2⁵×3×5×19 - 9120
