Answer:
a. p = 0.5
b. SE = 0.0525
Step-by-step explanation:
a. The sample proportion (p) of households that own a Company A product is given by the number of people who answered "yes"(34) divided by the sample size (n=68)
The sample proportion is 0.5.
b. If the population proportion is P = 0.75, the standard error is given by:
The standard error is 0.0525.
Answer:
3x and 5x
Step-by-step explanation:
im not sure how to explan this but the both jave the same variable so yea
Answer:
6x - 4 = 32. The variable (times a number) is equal to 6.
Step-by-step explanation:
So this equation is basically asking you to formulate an equation using only the words given. For this equation, let's use a variable in place of the part where it says "times a number." When a question says that phrase, that means that they are telling you to use a variable in place of a mystery number. A variable is a letter in place of a mystery number. Knowing this, let's now solve the equation. We will use the variable x in place of our mystery number.
Four less than 6 times a number: 6x - 4 _ __.
Now we can add the equal sign and the 32: 6x - 4 = 32.
We can now solve. Add 4 to both sides of the equation to cancel out the -4:
6x - 4 = 32
<u>+4 + 4</u>
6x = 36
Now we divide 6 into both sides of the equation to single out the x.
<u>6x = 36</u>
6 6
36/6 = 6, so:
x = 6
I hope that this helps.
The nth term of the equation would be:
Tn=an+b
a=constant difference
b= term 0 (term before first term)
Tn=3n-30
A) 126=3n-30
n=52 (valid because it is positive)
B) 461=3n-30
n=163.67 (invalid because it is not a whole number and a position needs to be a whole number)
C) 657=3n-30
n= 229 (valid)
D) 501=3n-30
n= 177 (valid)
Your answer is B
