Answer:
<h2>
cos 30°= 0.866</h2>
Step-by-step explanation:
Step one:
Applying the SOH CAH TOA principle
assuming all dimensions are in cm
Step two:
Given data
opposite= 1 cm
hypotenuse= 2 cm
<h3>we can now solve for θ</h3>
Sin(θ)= opp/hyp
Sin(θ)= 1/2
Sin(θ)= 0.5
θ= sin-1 0.5
θ= 30°
hence from tables cos 30°= 0.866
Answer:
6
Step-by-step explanation:
-6(2+a) = -48
-6 × 2 + -6 × a = -48
-12 - 6a = -48
-6a = -48 + 12
-6a = -36
a = -36/-6
a = 6
hope you understood!
Answer:
To answer you question, we need the confidence internals formula, μ±Zc*(σ/); N is the 20 psychology students, 0.5 the desviation standar and 4.3 is the medium based on national data, every fact in years.
Step-by-step explanation:
You need to consult the Zc value, you can find this table attached in this question; for 95%, we have a Zc value of 1.96.
Next step replace values: 4.3±1.96*(0.5/) = 4.3±0.22 (rounding the result)
So, the confidence interval are:
4.08cm≤X≤4.52cm
Answer:
<h2>
N=11</h2>
<h2>
Step-by-step explanation:</h2><h2>So you do 396 divided by 12=33</h2><h2>she sold 3 more wallets so then u would do 33 divided by 3 which would equal = <u>
11</u></h2>
