Answer: 0.0328
Step-by-step explanation:
Standard error is the standard deviation of the sampling distribution.
The formula to find the standard error is given by :-
,where n= sample size.
= Sample proportion.
Given : Of the 2266 high school students surveyed, 952 admitted to smoking marijuana at least once.
A study done 10 years earlier estimated that 45% of the students had tried marijuana.
i.e. Population proportion : p= 0.45
Sample size : n= 226
Sample proportion :
Then , the standard error for this test will be :-
Hence, the standard error for this test= 0.0328
Answer:
The total finance charge you will pay on this cash advance for the month is $60.50.
Step-by-step explanation:
Your bankcard has an APR of 9%.
So, monthly rate = = 0.75%
p = 2200
Simple interest = dollars
There is a 2% fee for cash advances.
So, cash fee for $2200 is = dollars
The total finance charge will be = dollars
Therefore, the total finance charge you will pay on this cash advance for the month is $60.50.
Answer:
Step-by-step explanation:
Start by writing these five numbers in just one format (improper fractions with denominator 10):
9/5 = 18/10, and
-2.5 = -25/10, and
-1.1 = -11/10, and
-4/5 = -8/10, and, finally
0.8 = 8/10
The smallest of these (the least) is -25/10, and
the largest is 18/10.
Arranged in ascending order, we have:
-25/10, -11/10, -8/10, 8/10, 18/10, or
-2.5, -1.1, -4/5, 0.8, 9/5
The points of intersection are at (3, 6) and (-1, -2).
Since both of these equations have y isolated, we can set them equal to each other:
2x=x²-3
We want all of the variables on one side, so subtract 2x:
2x-2x = x²-3-2x
0=x²-3-2x
Write the quadratic in standard form:
0=x²-2x-3
This is easily factorable, as there are factors of -3 that will sum to -2. -3(1)=-3 and -3+1=-2:
0=(x-3)(x+1)
Using the zero product property we know that either x-3=0 or x+1=0; therefore x=3 or x=-1.
Substituting this into the first equation (it is simpler):
y=2(3) = 6
y=2(-1)=-2
Therefore the coordinates are (3, 6) and (-1, -2).
1. 38 = thirty eight = treinta y ocho
2. 116 = one hundred sixteen = ciento
dieciséis
3. 573 = quinientos setenta y tres
4. 1,821 = one thousand eight hundred twenty one = mil
ochocientos veintiuno
5. 754,322 = seven hundred fifty four thousand three
hundred twenty two = setecientos cincuenta y cuatro mil trescientos veintidós
6. 6,615,010 = six million six hundred fifteen thousand
