The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
Answer:
z = 7/100
Step-by-step explanation:
Answer: interest = $ 3,629.34
Step-by-step explanation:
Complete question
(Marlie will be starting college next year, federal unsubsidized student loan in the amount of $18,800 at 4.29%. She knows that during this non-payment time, interest will accrue at 4.29%. Suppose Marlie only paid the interest during her four years in school and the six-month grace period. What will she now pay in interest over the term of the loan.)
This question relates to interest over a single period of time and since it's not compounded, we use formula for simple interest to calculate the interest accrued.
Data;
P = $18,800
R = 4.29% = 0.0429
T = 4.5 years
S.I = ?
S.I = PRT
S.I = 18,800 * 0.0429 * 4.5
S.I = $3,629.34
Therefore she'll need to pay $3,629.34 as interest accrued.
I would multiply 60 by 3, since its 300+%
60 x 3 = 180
From there I would then add at least half of 60, which is 30
180 + 30 = 210
Since it is 380, I would just add another 20 to the equation to get around :
210 + 20 = 230
This should be a good enough estimate that is close to 380% of 60 <span />
Answer:
b. sampling distribution of the mean.
Step-by-step explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
The probability distribution of the sample mean is called the sampling distribution of the mean and it's a graph of the sampled data (mean).
Mathematically, sampling distribution of the mean is given by the formula;
uX = u.
Where, uX is the mean of the sampling distribution of the mean.
A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called a two-tailed test. Thus, it is two sided and is typically used to test whether a sample is less than or greater than a set of values.
