Find the value of BC. HELP PLEASE!!
Masteriza [31]

It's an equilateral triangle, therefore

AB = BC = BA

We have the equation:

\dfrac{3}{2}x-12=\dfrac{1}{2}x-2\qquad\text{multiply both sides by 2}\\\\3x-24=1x-4\qquad\text{add 24 to both sides}\\\\3x=x+20\qquad\text{subtract x from both sides}\\\\2x=20\qquad\text{divide both sides by 2}\\\\x=10

BC=BA\to BC=\dfrac{1}{2}(10)-2=5-2=3

<h3>Answer: BC = 3</h3>

e mean IQ for 100 residents of the local apartment complex is 110. What is the best point estimate for the mean IQ for all resid
KengaRu [80]

Answer:

110 IQ too!

Step-by-step explanation:

For statistical problems, especially for ones with large enough sample sizes like this one (n = sample size = 100), the means for various samples is usually equal to the population mean.

It is the standard deviation of sample that differs from the standard deviation of the population through

σₓ = σ/√n

But, The mean of the sample = The population mean

μₓ = μ = 110 IQ

(b) Use the right-hand rule to decide whether the components of a × b are positive, negative, or 0.
Gekata [30.6K]

(a)

Given:  

\vec{a} is in xy plane and \vec{b} is in the direction of k.

|a|=6 units, |b|=3 and θ = 90°

|a × b| = |a| × |b| sinθ  

          = |a| × |b| sin90°  

          = 6 × 3 × 1  

|a × b| = 18  

(b)

Let \vec{c}=\vec{a} \times \vec{b}

\vec{c} is perpendicular to both \vec{a} \text { and } \vec{b}.

In this case,

x-component of \vec{a} \times \vec{b} is positive.

y-component of \vec{a} \times \vec{b} is negative.

z-component of \vec{a} \times \vec{b} is zero.
