Answer:
20 months approx
Step-by-step explanation:
Given data
Price=$2,350
Monthly savings= $115 per month
Hence the duration of time to save up $2,350 is given as
=2,350/115
=20.434
Hence the time is 20 months approx
Answer:
Check the explanation
Step-by-step explanation:
Let
and
be sample means of white and Jesse denotes are two random variables.
Given that both samples are having normally distributed.
Assume
having with mean
and
having mean 
Also we have given the variance is constant
A)
We can test hypothesis as

For this problem
Test statistic is

Where

We have given all information for samples
By calculations we get
s=2.41
T=2.52
Here test statistic is having t-distribution with df=(10+7-2)=15
So p-value is P(t15>2.52)=0.012
Here significance level is 0.05
Since p-value is <0.05 we are rejecting null hypothesis at 95% confidence.
We can conclude that White has significant higher mean than Jesse. This claim we can made at 95% confidence.
Answer:
<h2>p = (rt)/i</h2>
Step-by-step explanation:

Answer:
k=-1
Step-by-step explanation:
check is the equation goes through the point (-2,4)
4=-(-2)+2
4=2+2
4=4
this line goes through the point (-2,4)
