Answer:
x=-4
Step-by-step explanation:
3x plus 4 =-8
3x=-8 -4
3x÷ -12 and you get -4
A. If you were to graph the parabola using a table, you would get that its max height would be 16 feet, and it would get there in 3/4 of a second (t).
Answer:
80%/100%×$24
Step-by-step explanation:
I don't see any options here so let's work it out.
If all prices are reduced by 20%,it implies that 80% of the original value is charged to the buyer as sales price.
Since original value of the pants is $24-100%
then sales value(80%)=(80%/100%×$24)
Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
