fraction numerator negative 12 over denominator x end fraction
C.
negative 12 plus 2 x
D.
negative 12 x
Answer:
See explanation below
Step-by-step explanation:
We are going to transform the given phrase to an equivalent algebraic expression, let's x be a number:
a) The product of -12 and a number (we have to multiply)
(-12)x = -12x
b) The quotient of -12 and a number (quotient means division)
c) Twice the sum of -12 and a number (we're going to sum up -12 and a number and then multiply by 2)
2(-12 + x)
d) The sum of -12 and twice a number (we're going to sum up -12 and the double of the number)
-12 + 2x

Therefore the correct answer is for the alternative hypothesis is,
A null hypothesis is a theory that assumes there is no statistical importance between the two variables in the hypothesis.
Let be the proportion of the internet sales and be the proportion of the store sales.
The researchers claim is that ''the internet sales are more than 10% higher than store sales''.
The alternative hypothesis is,
The opposite of alternative hypothesis is,
It can be observed that the alternative hypothesis contains greater than a symbol.

Answer:
Step-by-step explanation:
We are given the following in the question:
Let be the proportion of the internet sales and be the proportion of the store sale.
Hypothesis:
We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.
Thus, we can design the null and alternative hypothesis as:
Alternate Hypothesis:
The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.

hi .................
Correct answer is: P(x<6) is 0.123 and it is usual.
Solution:-
Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90
Then probability of individual takes less than 6 minutes is
P(X<6) =
=
= 0.1230
Typically we say an event with a probability less than 5% is unusual.
But here P(X<6) = 0.123 is greater than 5% hence this is usual.
