castortr0y [4]

Answer:

The claimed proportion (population) is

p=0.11

The sample proportion (p-hat) is

\hat{p}=0.10

Step-by-step explanation:

In the population, we have the parameter p that is 11%.

p=0.11

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

\hat{p}=0.10

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.

What is the component form of the vector represented by 2a when a⃗ =〈−2,3〉?
Paladinen [302]

Answer:

\vec v = 2\cdot \vec a = \langle -4,6 \rangle

Step-by-step explanation:

Let \vec a = \langle -2, 3 \rangle, we need to determine \vec v = 2\cdot \vec a, which can be found by applying the following property:

\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle, \forall \,\alpha,x,y\in \mathbb{R} (1)

Then,

\vec v = 2\cdot \langle -2,3 \rangle

\vec v = \langle -4,6 \rangle

Solve for q<br> (Please show all work thank you:))
Masja [62]

Answer:

q = ±  \frac{5}{4\sqrt{p} }

Step-by-step explanation:

We are to solve for q in:

16pq² = 25

q² = \frac{25}{16p}

\sqrt{q^2} = ±\sqrt{\frac{25}{16p} } = ± \frac{5}{4\sqrt{p} }
