Y=-1x+11.
I used an online graph for this and it would be tricky on paper.
Answer:
x=-21
Step-by-step explanation:
The equation would be as follows:
x/7=-3
We work backwards by multiplying 7 by -3.
7*-3=-21
x=-21

Answer:
1. The corresponding sides of the two triangles must be proportional.
Step-by-step explanation:
Option 1, is the only statement that makes GHI = JKL true. If the triangles are congruent, it means that the sides have to be proportional.
Answer:
$12600
Step-by-step explanation:
If x represents the total investment, then the total interest is ...
(x/3)(0.02) +(x/3)(0.07) +(x/3)(0.08) = 714
x(.17) = 2142 . . . . multiply by 3; collect terms
x = 2142/0.17 = 12600
The total investment was $12,600.
Answer:
0.2207
Step-by-step explanation:
Here, we want to find the probability that the sample mean is greater than 25.
What we use here is the z-scores statistic
Mathematically;
z-score = (x-mean)/SD/√n
From the question;
x = 65, mean = 63, SD = 13 and n = 25
Plugging these values in the z-score equation, we have
Z-score = (65-63)/13/√25 = 2/13/5 = 0.77
So the probability we want to calculate is ;
P(z > 0.77)
This can be obtained from the standard normal distribution table
Thus;
P(z > 0.77) = 0.22065 which is 0.2207 to 4 d.p
