Answer:

x + 10y

Step-by-step explanation:

To simplify this question, we need to collect like terms. For terms to be considered like terms, they have to have identical variables with identical exponents. Coefficients may be different. So 4x and 3x are like terms. 8y and 2y are also like terms.

4x + 8y - 3x + 2y = x + 10y

Answer: $H_0:\mu=40$

$H_0:\neq40$

An alternative hypothesis says that there is a statistical significance between two variables.

Claim 1. : Mean age of online dating service users is 40 years.

i.e. $\mu=40$ , since it has equals sign so we take this as null hypothesis.

Claim 2. : Mean age of online dating service users is not 40 years.

$\mu\neq40$

⇒ Null Hypothesis : $H_0:\mu=40$

Alternative hypothesis : $H_0:\neq40$

Angle Sum Theorem. y = ?

salantis [7]

Answer:

90°

Step-by-step explanation:

Interior angles of ALL triangles sum to 180°

The whole large triangle has angles 60 60 60 ( they sum to 180)

that means x = 30

then the small triangle on the right has 60 + 30 + y = 180

meaning y = 90 °
