There are 3 choices for the pants. Having selected a pair of pants there are 2 choices for a shirt. Therefore there are 3 * 2 possible choices for a pair of pants and a shirt. Each of these 6 possible choices can be combined with each of the 3 possible choices of a pair of shoes. So, the total number of choices of outfit is given by:
Blue beads: 100/130, which reduces to 10/13.
Red beads: 20/130, which reduces to 2/13.
You're just taking the fraction of the certain color of beads compared with the total number of beads, which is 130.
Answer:
$14400
Step-by-step explanation:
Given data
Principal= 6000
Time= 14 years
Rate= 10%
Let us use the simple interest expression to find the final amount
A=P(1+rt)
substitute
A=6000(1+0.1*14)
A=6000(1+1.4)
A=6000*2.4
A=$14400
Hence based on a simple interest model the final amount is $14400
Answer:
Step-by-step explanation:
- The Z-score allows you to decide if your sample is different from the population mean. In order to use z, you must know four things:
- The population mean.
- The population standard deviation.
- The sample mean.
- The sample size.
- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.
- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).
Answer:
y= 7
Step-by-step explanation:
Plug in values into y=mx+b
m= slope
b= y intercept
Since slope is 0, y will always be at 7.
y= 0(x) +7
y= 7
