Answer:
28
Step-by-step explanation:
Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.
SIN(?) = 10/21
? = ARCSIN(10/21)
? = 28.437
3.2(10)+m(10)=85 this is the correct equation to find how much he walks every morning
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
True mean(μ) = 77.9
True standard = 20
Sample size (n) = 50
Sample mean (m) = 82.1
Sample standard deviation (s) = 18.6
The standard error (SE) :
SE = sample standard deviation / √sample size
SE = 18.6 / √50
SE = 2.6304372
SE = 2.63
Find common denominators ...12 then subtract
If you have to change each to a decimal or fraction then
32% = 0.32 or 32/100, 6% = 0.06 or 6/100, 93% = 0.93 or 93/100, 150%= 1.50 or 150/100,
