Answer:
No solutions .........
Step-by-step explanation:
3x-4y=7
-12x+16y=10
Multiply 1st equation by 4, you get:
12x-16y=28
Add the 1st and 3rd equations:
0x+0y=38
0(x+y)=38
(x+y)=38/0 which is undefined
The answer would be D) no, these triangles are not similar. I'm pretty sure they would be similar if one of the answer choices said ΔABC ~ ΔCED
Answer:
$4026.52
Step-by-step explanation:
Given data
rate= 5%
time= 3years
A=$4630.50
P=?
we know that
A=P(1+rt)
$4630.50=P(1+0.05*3)
$4630.50=P(1+0.15)
$4630.50=P(1.15)
P=4630.50/1.15
P=$4026.52
The intitial amount is $4026.52
Using the <u>normal distribution and the central limit theorem</u>, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.
Normal Probability Distribution
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, for n instances of a normal variable, the mean is
while the standard deviation is
.
In this problem:
- Mean of 4 candies, hence
. - Standard deviation of 1.5 candies, hence
. - She visited 35 houses, hence

The probability is the <u>p-value of Z when X = 122</u>, hence:

By the Central Limit Theorem



has a p-value of 0.
Approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.
